Abstract Many agricultural landscapes offer few resources for maintaining natural enemy populations and floral plantings have frequently been adopted to enhance biological pest control in crops. However, restored margins may harbour both pests and natural enemies. The aim was to compare the abundance of pests and natural enemies in three types of margins (unmanaged, sown herbaceous floral strips and shrubby hedgerows) as well as in adjacent melon fields. Besides, yield was compared among melon fields as way of testing the effect of the type of margin on biocontrol. The research was carried out during 2 years in twelve melon fields from four different locations in southern Spain. Arthropods were sampled periodically in margins and melon fields by visual inspections and Berlese extraction. Hedgerow and floral strips hosted higher numbers of both pests and predators than unmanaged margins. Besides, hedgerows had a similar or higher number of natural enemies than floral strips but lower number of pests. In just a few occasions, the type of margin had a significant effect on the abundance of pests and natural enemies in melon fields, but rarely there was consistency between the two growing seasons. No differences were found in yield. We hypothesised that the lack of association in the abundances of pests and natural enemies between margins and melon fields could be attributed to the overriding effects of the landscape and/or the internal population dynamics of arthropods in melon fields. Overall, shrubby hedgerows are more recommended than herbaceous floral strips.

Abstract The time it takes for an ecosystem to recover from a disturbance is a key to environmental management. Conventionally, recovery is defined as a return to the pre‐disturbance state, assuming ecosystem stationarity. However, this view does not account for the impact of external forces like climate change, imposing non‐stationarity and trends. Alternatively, the counterfactual approach views recovery as the state the ecosystem would have achieved if the disturbance had not occurred, accounting for external forces. Here, we present a simple method to estimate the counterfactual recovery time. By implementing our method to the greening of the Arctic region, we showed that counterfactual greening recovery is twice as long as conventional recovery over the region. We argue that the well‐documented greening of the region acts as an external force, leading to such a large difference. We advocate for embracing the counterfactual definition of recovery, as it aligns with realistic decision‐making processes.

EU countries, in particular the Czech Republic, are developing structural mechanisms to influence the development of their economic model in the environmental sphere. The study of the Czech Republic’s experience in implementing environmental reforms is relevant for understanding their impact on the country’s economic sustainability and fulfilment of international obligations. The purpose of the study was to analyse the regulatory framework and results of the reforms implemented in the environmental policy of the Czech Republic and their impact on the country’s further development. The results were obtained using special legal methods, such as terminological, formal legal and special legal methods. Identification of the main environmental problems, reformed economic sectors and the intensity of human activity’s impact on nature, determination of stakeholders in the changes and identification of the problems solved allowed us to conclude that the measures taken were rational and varied in their effectiveness. The analysis of the environmental and regulatory framework of environmental policy in the Czech Republic and the adopted environmental legislation, such as CO2 emission quotas, rational use of natural raw materials, waste management, green taxes, benefits and subsidies for the functioning of markets for environmental goods and services, showed the undeniable advantages of an environmentally oriented economic model over the one focused on profit. The study found that the application of such measures helps to reduce the negative impact on the environment, improve the quality of life of the population and ensure sustainable economic development. Incentives for companies that implement environmentally friendly technologies stimulate innovation and reduce production costs. Legislation plays a significant role in this, in particular, the Law of the Czech Republic No. 165/2012 Sb. The results of the study can be used by researchers from around the world who study the implementation of new methods of environmental policy

Although the implementation of area-wide inoculum reduction and Asian citrus psyllid control are decisive in controlling Huanglongbing (HLB) epidemics, growers continue looking for enhanced nutritional and/or resistance inducer (ENRI) treatments to mitigate yield damage in HLB-affected trees. Therefore, an experiment was set up in an 8-year-old sweet orange orchard to evaluate the effects of the foliar application of nutrients, phosphite, and salicylate sprayed four to five times per year during flushing periods. The trial had eight treatments in four randomized blocks. HLB incidence and yield were assessed from December 2010 to January 2017. HLB-symptomatic trees with less than 5% HLB severity were selected from each plot in the first (Group 1), second (Group 2), and third years (Group 3) after the beginning of treatments to assess the frequency of trees with different HLB symptoms and micronutrient deficiencies, HLB severity, and fruit yield until January 2017. Twenty asymptomatic trees from each plot were also harvested for comparison each year. ENRI treatments did not reduce the progress of HLB incidence in the plots or the HLB severity progress or frequency of HLB symptoms in the selected trees. ENRI treatments did not improve the yield of symptomatic trees compared with asymptomatic trees. Hence, in a scenario without HLB-symptomatic tree removal in mature orchards, disease severity progress and yield reduction in HLB-affected trees remained regardless of ENRI treatment.

The article summarizes scientific approaches to the development of the theory of changes in the greening of business. The scientific and methodological approaches to understanding the basics of the theory of change have been developed. The features of the application of the theory of change in the greening of business are presented. The specifics of the development of the theory of changes in the greening of business on the example of Ukraine are revealed. It is determined that for the Ukrainian realities, the greening of business is implemented mainly in the formal plane in the context of compliance with the norms and standards of environmental development, ensuring environmental taxation, control of environmental pollution standards, which slows down the development of the component of the Ukrainian environmental business and hinders the innovative introduction of elements of the ecological paradigm in our country. The theory of change is a rigorous but necessary process by which groups and stakeholders in planning activities formulate their long-term goals and define the conditions that they believe should precede the achievement of these goals. These conditions are modeled as desired outcomes, organized graphically in a causal structure. Change theory describes the types of interventions (a single program or a coordinated initiative) that lead to the outcomes depicted in the outcome map. Each intervention is linked to an outcome in a causal system, revealing the often complex web of actions required to bring about change. Several factors have been found to make it difficult for multinational companies to take action against climate change, such as a lack of certainty about climate policy, a lack of green technologies, and a lack of return on investment. The use of green practices also remains limited in the International Health Standards (IHR) in both developed and developing countries, due to limited access to finance and skills, lack of information and knowledge about innovation, and, in some cases, poor enforcement of rules. It is determined that for a better and more effective application of the norms and provisions of the theory of changes in the greening of business, it is relevant to introduce professional courses for managers and environmental managers of companies, which will direct the professional training of management staff to the implementation of effective environmental changes in business. It is also relevant to introduce the State-based programs to stimulate the development of greening business in terms of indirect (tax incentives for businesses that implement environmental innovations) and direct incentives for the implementation of environmental changes (preferential lending for greening business).

Introduction. Environmental certification in accordance with ISO 14001 and EMAS makes it possible to understand and assess the impact of economic activities on ecosystems, as well as to set environmental goals and objectives for improving the activities of enterprises and organizations. The effects of the EMS (environmental management and audit scheme) depend on how companies decide to use them after certification. In this regard, the authors investigate the organizational climate issues associated with the use of ISO 14000 and EMAS series standards to improve the environmental efficiency of companies.Materials and methods. The methodology is presented in the form of an environmental safety model related to the enterprises and organizations, including environmental audit, environmental standardization and environmental assessment of compliance with various environmental requirements at different levels of organization of enterprises’ activities. The object of research is the international environmental standards of the ISO 14000 and EMAS series. The subject of the study is the environmental safety of negative factors in the activities of enterprises and organizations. The concept of the necessity of greening personnel training and a positively environmentally oriented organizational climate in enterprises and organizations is proposed.Results. The implementation of EMS does not always lead to an improvement in the environmental performance of companies. Some companies focus on formal criteria without taking into account real environmental problems. In addition, environmental indicators can take the form of coefficients and can be improved with unchanged or even worsened environmental impact. The organizational climate is important for the realization of EMS goals, especially the attitude of employees to the environment and environmental values. Despite limitations, EMS, environmental audit and ISO 14000 principles can help companies reduce their negative impact on the environment and increase their competitiveness, as well as make more informed choices when planning their activities.Conclusions. The importance of creating an organizational climate for the successful greening of negative factors in the activities of enterprises and organizations is emphasized. There is also a need for a more accurate assessment of the effectiveness of environmental measures when formulating environmental standards and assessing compliance with their implementation.

Climate change has resulted in a widespread increase in primary productivity in northern regions. This “greening” can alter terrestrial ecosystems dynamics and trigger positive climate feedbacks but often exhibits spatial heterogeneity. Few studies have focused on the differential responses of plant functional groups to warming as a potential driver of heterogeneity in greening rates. Our objective was to determine whether climate–growth relationships are species-specific, and whether they can explain the heterogeneity of the subarctic greening rates. We compared climate–growth relationships and associations to normalized difference vegetation index (NDVI) of the dominant tree (Picea mariana) and shrub (Betula glandulosa) species at two locations in the forest–tundra ecotone in Nunavik (Québec, Canada). Correlation coefficients of the climate–growth relationship varied between species and locations, being higher for P. mariana and at the northernmost location. The lower association between NDVI and P. mariana radial growth at the northernmost location appeared to be compensated by a stronger association between NDVI and B. glandulosa radial growth. Our results show that response to climate varies spatially and between species, both of which could potentially be used to explain the heterogeneity of subarctic greening rates. This improved understanding of the species-specific response to climate change will help predict forthcoming changes in primary productivity and their potential positive feedback on climate change.

Vegetation greening not only offers climate benefits but also enhances residents' well-being in urban areas. China and India lead the world in terms of global greening. However, systematic studies summarizing the green development levels of both countries are still lacking. Here, we explore the regional significant greening levels and spatial distribution characteristics of China and India across multiple spatial scales using the significant greening level as an indicator. Additionally, we analyze the diverse relationships between significant greening in China and India and factors such as land use, economy, and population. The results indicate that areas with significant greening in China are primarily located in some mountainous regions in the central and eastern parts, while in India, areas with significant greening are mainly distributed in plain and plateau regions. Within significantly greening areas, 55.57% in China are forests, and 95.67% in India are croplands. The greening level in built-up areas in China is mostly positively correlated with economic factors, but in economically disadvantaged areas, the greening level is not necessarily the lowest. In Indian built-up areas, the greening level is negatively correlated with the economy. Regarding the relationship with urbanization, the greening level in the surrounding areas of built-up areas in both China and India generally decreases with the increasing degree of urbanization's influence, but the damage caused by urban development to the greening level in India is much higher than in China. 83% of cities in China have medium-range per capita greening levels, while 60% of cities in India have per capita greening levels in the lower range. A systematic analysis and summary of China and India's greening development can provide strategic references for other developing countries to enhance greening initiatives and improve their level of sustainable development.

State of the problem. During the occupation by Armenia of the Karabakh economic district of the Republic of Azerbaijan, the military degradation of agricultural lands and their use in agriculture and animal husbandry without observing agroecological rules led to the deterioration of soil fertility and the reduction of the optimality of agrarian landscapes. Object learning. The article presents modern ideas for re-doing the agroecological assessment of the lands and solving the actual agroecological problems of their use in agriculture for greening the development of the agricultural area in the Karabakh economic region. In the economic region, the main approach is given to methodological issues of agro-ecological assessment of soil quality, greening of efficient use of agricultural land, agro-ecological analysis of anthropogenic dynamics of soils, regional integration of assessment of agro-ecological quality of soils. In the design of agroecosystems in the Karabakh economic region, the agroecological approach of the differentiation of the area according to the soil-climate factors, the evaluation of the soil taking into account the geomorphological and climatic factors is given. At the same time, the importance of cadastral assessment and accounting of the modern ecological condition of the region's land resources, as well as the issues of their effective use and protection are explained. In the article, in order to ensure the development of the agrarian sector in the region, the importance of the complex agro-ecological re-evaluation of land resources, ways to eliminate the main indicators of land degradation and ecological requirements for the cultivation of plants, determination of territorial units characterized by variability of natural and climatic conditions, agro-production grouping of elementary areas of agro-landscapes and according to the agro-ecological assessment of the area, the ways of organizing the efficient use of land were investigated. Methodology. Generalization, historical, statistical, systematic analysis, and comparison methods were used to prepare the article. Research results. Environmental and economic stability may become more challenging in the future due to increasing anthropogenic pressure on agroecosystems in the economic region and poor infrastructure. Due to intensive land use, frequent erosion, river floods, and environmental pollution in the region can lead to a decline in the quality of agricultural land. Also, anthropogenic activities in the region can have a negative impact on the state and development of agroecosystems and the sustainable development of agriculture in the region, to optimize which it is considered necessary to improve and update the methods and technologies used in agriculture. The scientific novelty of the research. It is necessary to apply agroecological concepts and principles in the redesign, development, and management of sustainable agricultural systems in the economic region. The development of agroecosystems in the region should be ensured by alternative agricultural methodologies and approaches that combine the socio-economic and historical context of agriculture. The production of organic agricultural products, which do not harm human health and the natural environment, should be carried out, and the ecological condition of the soil should also be monitored regularly.

In light of recently accelerating global warming, the changes in vegetation trends are vital for the monitoring of the dynamics of both whole ecosystems and individual species. Detecting changes within the time series of specific forest ecosystems or species is very important in the context of assessing their vulnerability to climate change and other negative phenomena. Hence, the aim of this paper was to identify the trend change points and periods of greening and browning in multi-annual time series of the normalised difference vegetation index (NDVI) and enhanced vegetation index (EVI) of four main forest-forming tree species in the temperate zone: pine, spruce, oak and beech. The research was conducted over the last two decades (2002–2022), and was based on vegetation indices data derived from the Moderate Resolution Imaging Spectroradiometer (MODIS). To this end, several research approaches, including calculating the linear trends in the moving periods and BEAST algorithm, were adapted. A pattern of browning then greening then constant was detected for coniferous species, mostly pine. In turn, for broadleaved species, namely oak and beech, a pattern of greening then constant was identified, without the initial phase of browning. The main trend change points seem to be ca. 2006 and ca. 2015 for coniferous species and solely around 2015 for deciduous ones.

Postharvest fibrosis and greening of Toona sinensis buds significantly affect their quality during storage. This study aimed to clarify the effects of low-temperature storage on postharvest red TSB quality harvested in different seasons. Red TSB samples were collected from Guizhou province, China, 21 days after the beginning of spring (Lichun), summer (Lixia), and autumn (Liqiu), and stored at 4 °C in dark conditions. We compared and analyzed the appearance, microstructure, chlorophyll and cellulose content, and expression levels of related genes across different seasons. The results indicated that TSB harvested in spring had a bright, purple-red color, whereas those harvested in summer and autumn were green. All samples lost water and darkened after 1 day of storage. Severe greening occurred in spring-harvested TSB within 3 days, a phenomenon not observed in summer and autumn samples. Microstructural analysis revealed that the cells in the palisade and spongy tissues of spring and autumn TSB settled closely during storage, while summer TSB cells remained loosely aligned. Xylem cells were smallest in spring-harvested TSB and largest in autumn. Prolonged storage led to thickening of the secondary cell walls and pith cell autolysis in the petioles, enlarging the cavity area. Chlorophyll content was higher in leaves than in petioles, while cellulose content was lower in petioles across all seasons. Both chlorophyll and cellulose content increased with storage time. Gene expression analysis showed season-dependent variations and significant increases in the expression of over half of the chlorophyll-related and cellulose-related genes during refrigeration, correlating with the observed changes in chlorophyll and cellulose content. This research provides valuable insights for improving postharvest storage and freshness preservation strategies for red TSB across different seasons.

The European Green Deal and the European Climate Law highlight the EU’s commitment to strive for carbon neutrality. Considering the magnitude of the global challenge, it is evident that a green transition will not succeed without the efforts of every sector, including financial institutions. Concerns have been raised that central banks may, in fact, contribute to the increase of greenhouse gas emissions and, in consequence, aggravate global warming. This all has currently resulted in a rapid expansion of the debate on the potential role of central banks, and in particular the ECB, to consider climate objectives. In the European context, however, it is often argued that environmental sustainability lies outside the ECB’s traditional core mandate to focus on price stability. This article aims to introduce the environmental integration principle, laid down in Article 11 TFEU, in the ECB’s legal framework, and provide an analysis of the possibilities for and limitations to the greening of the ECB's monetary policy based on this provision. Although Article 11 TFEU has great potential with regards to the greening of sectoral policies, in legal literature, the provision has not gained enough academic attention in terms of the financial sector.

Seedling greening upon irradiance is essential for the survival of plant after germination. Here, we studied the role of nitric oxide (NO) in regulating the accumulation of chlorophyll during greening of Arabidopsis seedlings, and we also investigated the changes of ATP in the chloroplast and cytoplasm during greening by using a fluorescent protein sensor (Ateam 1.03-nD/nA) based on fluorescence resonance energy transfer (FRET) and the effects of NO on the changes of ATP content. The results showed that the content of NO, chlorophyll, and ATP in the chloroplast and cytoplasm increased with the increase of greening time. L-NAME, an inhibitor of NO, not only decreased the accumulation of chlorophyll content but also reduced the ATP content in the chloroplast and cytoplasm during the greening of Arabidopsis seedlings. Therefore, these experiments indicate that the accumulation of chlorophyll and changes of ATP during greening of etiolated Arabidopsis seedlings are mediated by nitric oxide.

Abstract Earth's vegetation has been increasing over the past decades, altering water and energy cycles by changing evapotranspiration (ET). Greening, caused by climatic and anthropogenic factors, has high rates in High Mountain Asia (HMA). Here we focus on two HMA basins (the Yangtze and the Ganges‐Brahmaputra) to contrast the impacts of climate‐ and human‐induced greening on ET. Though the rate of greening is similar in both basins, anthropogenic influences lead to dissimilar responses in ET. In the Yangtze, climate‐induced greening increases ET, with the increase in moisture being high enough to meet the ET demand. In the Ganges‐Brahmaputra, irrigation‐induced greening does not alter annual ET, only pre‐monsoon ET increases. The dry season declines in water storage due to pumping decrease ET, while laboriously meeting the demand. This study provides a representative example of the contrasting influences of climate induced and anthropogenic driven processes on the seasonality of ET.

Wetting and drying climate sequences and anthropogenic vegetation changes can have profound effects on the hydrological cycle and sustainability of terrestrial ecosystems. China contains many different climates, from humid to extremely arid and it contributes to the global mitigation strategies of climate change. China is also an important contributor to global greening and carbon sequestration. In view of this, we estimated the spatial and temporal variation of leaf area index (LAI), dryness/wetness index (DWI), and soil moisture (SM) in arid (A), semi-arid (SA), semi-humid (SH), and humid (H) climate zones during 1981–2018 in China and analyzed the patterns of DWI and LAI effects on SM under different vegetation greenness. The results showed a significantly increasing trend of LAI in all climatic zones, and the contribution was from highest to lowest: SH (8.17 × 10-3 m2 m−2 year−1), SA (7 × 10-3 m2 m−2 year−1), H (4.71 × 10-3 m2 m−2 year−1), and A (3.98 × 10-3 m2 m−2 year−1). The SA and A zones are becoming wetter, while the soil of SH and H zones are drying. The dry/wet climate variation plays a decisive role in soil moisture, while the role of vegetation is limited. Additionally, the LAI3 (mean LAI from 2016 to 2018) thresholds were 0.25–0.41 and 0.84–0.86 for A and SA as a whole, respectively, as well as 0.47–0.54 and 0.93–1.18 for grassland, respectively. When vegetation exceeded this threshold, the effect of vegetation on soil moisture showed a shift from increasing to decreasing change. Overall, the results of the study provide improved understanding of the atmosphere-soil-vegetation interactions under climate change, as well as effects of vegetation restoration and water conservation efforts.

Agriculture is the main land use and one of the main drivers of biodiversity loss. In particular, intensive farming practices have contributed to biodiversity loss, which is why many governments have implemented agri-environmental schemes (AES). Farmer collaboration at landscape level is important to achieve effective AES. The Dutch government opted for such an approach and decided that only farmer collectives were entitled to take part in AES. In this paper, we evaluate 36 Dutch farmer collectives. Through the lens of professionalisation, we investigated which characteristics of professionalisation enable farmer collectives to work towards an effective AES in terms of collaboration at landscape level. We used spatial concentration of conservation measures as a measurement of an effective AES and, based on expert judgement, selected five characteristics of professionalisation that directly impact AES effectiveness. We applied a fuzzy-set Qualitative Comparative Analysis (fsQCA) in order to explore which of these characteristics singly or in combination contribute most to spatial concentration. We found that different combinations of characteristics of professionalisation enable farmer collectives to work towards spatial concentration. First, we found that working on the maintenance and development of qualifications of participants is for most farmer collectives important to work on more spatial concentration. Second, the combination of having a strategy for agrobiodiversity in combination with working on the qualifications of the field workers is important. And when the network capability or the presence and use of enabling systems are missing, the qualifications of the field workers is important. Based on our findings, we conclude that the qualifications of participants and fieldworkers (i.e., regional coordinator, ecologist and field officer) are the most important characteristics of professionalisation to contribute to spatial concentration at the moment.

Urban green plantings have been recognized as an important component of the urban ecosystem. Inspecting the health of trees in settlements, in territories, near footpaths and highways is required regularly. In the city of Apatity, Murmansk Oblast, the state of the Siberian stone pine (Pinus sibirica Du Tour) trees was studied, the presence of risk factors in the environment of the tree and damage that characterize the accident rate of the tree were determined. Visual inspection aims to identify symptoms of structural defects that may compromise the stability of the tree. Root zones, tree stems, crown base, skeletal branches, crown were assessed. The presence of hollows, cracks, signs of decomposition, fruiting bodies of fungi, damage and wounds, weak forks, dead branches were indicated. Among the examined trees, Siberian stone pine trees with a high risk of falling were not found. In trees in street row planting, a sparse crown is more often noted, damage to the butt zone, including mechanical damage. The root system of all examined trees functions in conditions of limited space. Trees in a linear planting along the road and pedestrian zones have more pronounced restrictions on the development of the root system. Stem damage occurs in all examined Siberian stone pine trees. Recommendations have been developed for regular monitoring, tree health pruning and other agrotechnical measures. The study carried out is of great practical importance. The results of the study can be used in the development of recommendations for the formation of a favorable ecological environment in the urbanized territories of the Arctic zone of Russia.

In a context of ecological transition, the city of Casablanca has set itself the goal of building an eco-metropolis. Its development plan provides to convert industrial wasteland into business parks with consideration of sustainability in development operations. Sustainable management approaches have been initiated, such as the CasaNearshore Technopole greening project. The paper proposes an analysis of the perceptions of actors on the themes of actions to be implemented within the framework of this project. The evaluation by the actors of the relevance of these themes reveals that actions in favor of the preservation of the environment, although known as approaches of general interest, can nevertheless lead to situations of location conflicts.

The application of biotechnological methods in the metallurgical industry has the potential to provide an environmentally friendly and cost-effective direction of development. Thiobacillus ferrooxidans, a thionic bacterium, and the microalga Chlamydomonas reinhardtii TN-72 CH were used as complex reagents for extracting gold from sulfide mineral raw materials. The sorption properties of modal and productive multicomponent gold-bearing solutions were studied. The sorption characteristics of the biosorbents were compared with those of sorbents currently used in gold production — the synthetic resin AM2B and GoldCarb activated carbon. The conducted research studying the sorption properties and survival ability of the microalga C. reinhardtii TN-72 CH will make it possible to develop an industrial technology for extracting metal in the hydrometallurgical cycle of gold production. The use of microorganisms in gold hydrometallurgy as an alternative to cyanide methods will reduce the load on the environment while reducing the cost of the technology. In the process of leaching gold-bearing raw materials by microorganisms, even submicroparticles of gold are released, which makes the processing of poor and refractory ores promising. Preliminary biooxidation increases the effectiveness of thiosulfates in terms of both time and gold recovery.

People modify 56% of the Earth’s land. The world trend is changing from rapacious to considered influence such as green construction/production. Nevertheless, the terroristic war of the Russian federation against Ukraine causes the chaotic destruction and snowballing emissions from shell bursts and fires. Reclamation of land should attempt to repair the hugely dangerous influence of this, especially in the temporarily annexed lands of Ukraine. Donbas was one of the most stressed regions due to active mining and other industries, and contained more than 38% of Ukrainian damaged lands. The war deepens the situation. The most natural reconstructive measure is greening. The authors analysed the requirements for greening to gain the maximum benefits. Enduring and effective plant assortments were proposed for the region. For sanitizing the environment, experiments were performed with phytoncide activity using a photographic paper method. It was found and recommend that new phytoncide plants – Japanese quince (Chaenoméles japónica) and barberry (Bérberis) – were most effective.

Successive reforms of the Common Agricultural Policy (CAP) have led to increasingly shifting of agriculture towards the market, while integrating environmental protection requirements and strengthening support for rural development in all the Member States of the European Union. This article aims to present the results of our research on a) dynamic of the "greening" process in the rural area of the European Union to combat climate change; b) the funding mechanisms for the programs implementation and greening payments to farmers, revealing some critical considerations on how greening and agro -environmental measures were applied into the EU rural area in 2014-2020 and c) the perspectives of the greening process by 2021-2027, as well as the financial allocations in the new Multiannual Financial Framework. The results confirm the European Commission's ambitions regarding the Community's rural area in the context of the European Green Deal and the measures initiated under the European Recovery and Resilience Plan, in order to promptly overcome the health crisis caused by the COVID-19 pandemic.

Abstract Background Healthcare waste contributes substantially to the world’s carbon footprint. Our aims are to review the current knowledge of Interventional Radiology (IR) waste generation and ways of reducing waste in practice, to quantify the environmental and financial impact of waste generated and address green initiatives to improve IR waste management. Methods A systematic literature search was conducted in July 2022 using the Medline and Embase literature databases. The scope of the search included the field of IR as well as operating theatre literature, where relevant to IR practice. Results One-hundred articles were reviewed and 68 studies met the inclusion criteria. Greening initiatives include reducing, reusing and recycling waste, as well as strict waste segregation. Interventional radiologists can engage with suppliers to reformulate procedure packs to minimize unnecessary items and packaging. Opened but unused equipment can be prevented if there is better communication within the team and increased staff awareness of wasted equipment cost. Incentives to use soon-to-expire equipment can be offered. Power consumption can be reduced by powering down operating room lights and workstations when not in use, changing to Light Emitting Diode (LED) and motion sensor lightings. Surgical hand wash can be replaced with alcohol-based hand rubs to reduce water usage. Common barriers to improving waste management include the lack of leadership, misconceptions regarding infectious risk, lack of data, concerns about increased workload, negative staff attitudes and resistance to change. Education remains a top priority to engage all staff in sustainable healthcare practices. Conclusion Interventional radiologists have a crucial role to play in improving healthcare sustainability. By implementing small, iterative changes to our practice, financial savings, greater efficiency and improved environmental sustainability can be achieved.

The research relevance is due to the tasks set in the Concept of Sustainable Development of the United Nations. One of the state mechanisms through which the state can influence both producers and buyers to develop socially responsible behavior, which would contribute to the greening of industrial products, could be the organisational and economic mechanism of regulated procurement. The aim of the study was to reveal the specifics and assess this mechanism in relation to industrial products in terms of ensuring its environmental safety. The study was methodologically based on general scientific research methods. A set of activities that make up the specifics of organising regulated procurement are considered and technical recommendations are developed. Particular attention is paid to life cycle contracts. An original system of indicators, characterizing the current performance of the mechanism under consideration, has been formed within the framework of the generally accepted characteristics. The system of indicators developed makes it possible to comprehensively assess the industrial products’ regulated purchases, focused on ensuring their environmental safety, and analyse the effectiveness of each element of regulated procurement organisation.

Landscaping is making visual improvements to academic institutions, urban and other private organizations with plants and attractive materials. People all over the world are attracted to green and beautiful landscapes which initiate them to be happy and creative. Especially students in higher educational institutions who spend much of their time focused on their studies need of clean, green and attractively well-designed landscapes in their campuses. So far data on plant species composition and perception of university towards landscape work is lacking. With this understanding, the study was conducted to investigate plant species composition and community perception towards landscaping work executed at HawassaUniversity’s main campus using questionnaires, interviews, observation, and group discussion methods. In addition, vegetation data were collected using a systematic sampling method. In the study, 221 respondents were drawn from academic staff, administrative workers and students using random sampling method. Key informants were selected using purposive sampling method. In order to identify the plants species, systematic sampling along the transect line was employed. Twelve (12), 40m X40m(i.e.1600 m2)area quadrat plots were laid and all the plants species in the quadrats were collected and identified. The distance between each transect and quadrat was 200 mand 100m, respectively. 52 plant species with 44 genera and 29 families were recorded. The study showed that, the most dominant family wasFabaceaewith 9 species followed by Cupressaceae as well as Moraceae with 4 species each respectively. They results revealed that, campus landscaping work was the most significantly important and made the campus more attractive by plantation (61.1%), landscaping (27.1%) and walkways (5.7%). Plantation could also modify the micro-climate of the campus environment(94.3%) due to the plants photosynthesis process which produces O2and takesin Co fromthe atmosphere. In general educational institutions' landscaping need to be encouraged to enhance the teaching-learning process, and to make the working environment attractive. A great educational environment is guided by the most powerful teacher of all, nature itself.

Brewer's spent grain is a brewing industry waste product that contains various valuable biologically active substances. However, polymers can complicate their extraction. This article focuses on innovative extraction methods, including sustainable deep processing that destroys the internal structures of plant matrix. The research objective was to review publications on the sustainable brewer's spent grain processing as a source of secondary raw materials and plant matrix organic compounds. The study featured the last 5–10 years of foreign and domestic analytical and technical publications on grain structure and extraction methods. Unlike the traditional acidic, alkaline, and enzymatic methods of grain processing, physical and mechanical methods aim at extracting biogenic peptides, phenolic compounds, and fatty acids. The nature of the processing depends on the type of the extracted compound. Thus, for the extraction of reducing compounds intended for sorption, exposure to high temperatures (≥ 150°C) is the most effective method. A combined treatment with acids or alkalis of the cellulose-lignin complex makes it possible to achieve a 76.2% yield of hemicelluloses. Acid hydrolysis of arabinoxylans is effective at 120–160°C. Alkaline hydrolysis combined with physical treatment makes it possible to reach 60% of arabinoxylans in a mix with phenolic compounds. When extracting nitrogen-containing, phenolic, and lipid compounds, the degree of grinding of the biomaterial and the organic solvent is of great importance. The optimal degree makes it possible to preserve the spatial structure while maintaining a high yield (86%) of organic compounds. Ultrafiltration concentrates the isolated biogenic compound and preserves its activity with a high yield of up to 95%. The analysis proved that the brewer's spent grain processing can be both feasible and environmentally friendly. It produces a high yield of pure organic compounds, e.g., peptides, phenolic compounds, fatty acids, etc.

IntroductionWith social and economic development and the associated large-scale exploitation of natural resources, the number of slopes has significantly increased. As slope instability can lead to serious geological disasters, the ecological protection and reconstruction of slopes has become a hot topic of common global concern.MethodsIn order to achieve scientific slope management and overcome the difficulty of maintaining slope greening in the long term, this study explored eight strategies (A, B, C, AB, AC, BC, ABC, CK), involving different patented mineral solubilizing microorganisms (MSMs), and analyzed the field application of active permanent greening (APG) based on MSMs.ResultsThe results revealed that MSMs significantly increased the content of effective metal ions and available nutrients in soil and enhanced soil enzyme activity. Among all strategies, strategy A showed significant superiority, with soil effective calcium, magnesium, potassium, nitrogen, phosphorus and organic matter contents increasing by 51.62%, 55.41%, 30.42%, 39.77%, 181.69% and 76.92%, respectively, while urease, sucrase and peroxidase activities increased by 89.59%, 74.68% and 85.30%. MSMs strongly promoted the growth of Amorpha. Strategy A showed the best performance, with plant seedling height, ground diameter, leaf area, root length, and root volume increasing by 95.75%, 47.78%, 124.14%, 108.83%, and 139. 86%, respectively. According to a comprehensive evaluation using the entropy-analysis hierarchy process, strategy A has great potential for application. The field test results verified that APG has significantly better greening performance than the traditional greening method, with high vegetation cover and stable soil layer.DiscussionThe results of this study provide a reliable practical basis and technical reference for the development, promotion, and application of APG.

Knowledge of the dynamics of vegetation phenology is essential for the understanding of vegetation-climate interactions. Although the interest in phenology study is growing, vegetation phenology in Africa received far less attention compared to the Northern Hemisphere. Africa straddles the northern and southern hemispheres, and the climate has a clear latitudinal gradient, which facilitates the study of the interaction between phenology and climate. In this study, the latitudinal and longitudinal gradients and temporal trends of start of growing season (SOS), peak of growing season (POS), and end of growing season (EOS) were examined using long-term satellite dataset during 1982–2015. The latitudinal variations in these phenology metrics were larger in the northern than those in the southern Africa, especially from 6°N northwards to 16°N. The latitudinal variations in southern Africa had no clear patterns due to the more complex climate systems. For the longitudinal variation, the temporal trends in POS and EOS exhibited a gradient-decreasing rate in northern Africa. Over the period from 1982 to 2015, the overall trends of the phenology in Africa were ‘later SOS’, ‘later POS’, and ‘later EOS’. The faster rate of delay in EOS than in SOS resulted in a prolonged length of growing season (LOS) with 0.50 days/year on average in northern Africa, while a slower rate of delay in EOS than in SOS resulted in a shorter LOS with −0.12 days/year in southern Africa. The prolonged LOS in northern Africa contributes to the increase in the yearly-averaged Normalized Difference Vegetation Index (NDVI) from 1982 to 2000. Nevertheless, the NDVI appeared to have reached saturation around the 2000s, although the LOS was still extending after 2000s. Overall, the findings of this study provide an overall view of the spatial and temporal patterns of land surface phenology in the African continent, and a necessary component for future studies on the response of phenology to climate.

In the context of global warming, the frequent occurrence of drought has become one of the main reasons affecting the loss of gross primary productivity (GPP) of terrestrial ecosystems. Under the influence of human activities, the vegetation greening trend of the Loess Plateau increased significantly. Therefore, it is of great significance to study the response of GPP to drought in the Loess Plateau under the greening trend. Here, we comprehensively assessed the ability of vegetation indices (VIs) and solar-induced chlorophyll fluorescence (SIF) to capture GPP changes at different seasonal scales and during drought. Specifically, we utilized three vegetation indices: normalized difference vegetation index (NDVI), near-infrared reflectance of vegetation (NIRV), and kernel NDVI index (kNDVI), and determined the drought period of the Loess Plateau in 2001 based on the standardized precipitation evapotranspiration index (SPEI) and the standardized soil moisture index (SSMI). Moreover, the anomalies of VIs and SIF during the drought period and the relationship with GPP anomalies were compared. The results showed that both SIF and VIs were able to capture changes during the drought period as well as in normal years. Overall, SIF captured drought changes better due to water and heat stress as well as GPP changes compared to VIs. Across different time scales, SIF showed the strongest relationship with GPP (meanR2 = 0.85), followed by NIRV (meanR2 = 0.84), NDVI (meanR2 = 0.76), and kNDVI (meanR2 = 0.74), suggesting that SIF is more sensitive to physiological changes in vegetation. Notably, kNDVI performed best in sparse vegetation (meanR2 = 0.85). In capture during drought, NIRV and kNDVI performed better in less productive land classes; SIF showed superior capture as land use class productivity increased. In addition, GPP anomalies correlated better with kNDVI anomalies (meanR2 = 0.50) than with other index anomalies. In the future, efforts to integrate the respective strengths of SIF, NIRV, and kNDVI will improve our understanding of GPP changes.

There is an increasing disconnect between people and nature as we become more urbanised. Intensification in cities often results in a reduction of natural areas, more homogenised and manicured green spaces, and loss of biota. Compared to people in rural areas, urban dwellers are less likely visit natural areas and recognise and value biota. Reconnecting people with nature in the city not only benefits human mental and physical wellbeing but can also have positive effects on how people value biodiversity and act on conservation issues. However, in some contexts, the push to reconnect people with nature may have unintended negative outcomes on biodiversity, particularly if place-specific nature is not used in urban greening. In the current biodiversity crisis, using vegetation and green space design that is not reflective of the environmental context of a city can further disconnect residents, particularly Indigenous people, from their local environment and species, and further entrench extinction of experience and loss of environmental values. This disconnect can result in residents applying wildlife gardening practices, such as bird feeding, that are not specific to place, and benefit introduced species over indigenous species. Furthermore, cities are gateways for invasive species, and using species in greening projects that are not locally sourced has already left cities and their surrounding regions with a large weed legacy. Using place-specific nature and green space in cities can be less resource intensive, highly beneficial for biodiversity and give residents a unique sense of place. Rather than simply adding ‘more nature’ in cities, the messaging should be more complex, emphasising the need for urban greening to be context specific to avoid negative impacts on biodiversity and ecological and cultural services.

Modern environmental problems are the result of human-environment interaction in the process of industrialization. The relationship between economic development and environmental quality is an important aspect of understanding human-environment interaction and has been widely concerned by multidisciplinary researchers. Economic geography (EG) is a discipline that mainly focuses on the location and connections of economic activities. EG has developed to environmental economic geography (EEG) by incorporating environmental factors into its research framework, considering the operational mechanism of the co-evolution of economy and environment, and the dynamic process of green transition of techno-economic paradigms. Studying the resource and environmental effects of R&D, production, trade, and other aspects of the economic cycle is beneficial to realizing the “greening” economy. This paper traces the background and theoretical development path of EEG and elaborates on the interaction between EEG and other research paradigms on environmental problems. In recent years, the focuses of EEG are as follows: (1) the “location-environment” relationship of production from the perspective of local actors; (2) the “GVC/GPN-environment” relationship of multinational enterprises and space of flows from the perspective of the global network; (3) the “trade/circulation-environment” relationship from the perspective of national linkages; and (4) the co-evolution of the economic system and environment from the perspective of synergistic evolution, with a focus on innovation and institutional forces. The future development trend of EEG is combined with the endogenous growth theory and the sustainable development theory, mainly from the aspects of endogenous, system integration and multi-scale, to explain the differences in environmental issues of different regional economic activities, and to promote the development of EEG theory and interdisciplinary research, strengthening the construction of global and regional sustainable development system.

The purpose of the article is to substantiate the necessity of introducing ecological innovations into the activities of enterprises, to study the problems and prospects associated with the introduction of ecological innovations, and to make recommendations on increasing the ecologicalization of the activities of enterprises. Methodology. The work uses general and special scientific methods and techniques of cognition: methods of theoretical generalization, analysis, synthesis and grouping, logical-historical method, deduction and induction. It is pointed out that one of the means to ensure the balanced development of society is the introduction of ecological innovations in enterprises. This will contribute to the growth of economic well-being of business entities, ensure the competitiveness of their products, give an opportunity to enter the world market of goods and services, increase the level of environmental safety of the territory and the health of people living there. The results of the work show that the direct implementation of ecological innovations will ensure environmental responsibility of business, increase the efficiency of enterprises, increase consumer loyalty to products and, as a final result, high indicators of competitiveness of manufacturers while preserving the environment. Practical implications. Eco-innovations provide a gradual impact on sustainable development. Achieving the principles of sustainable development, refusing to achieve high rates of economic growth at the expense of future generations, stopping the processes of depletion of natural resources are possible only through the implementation of effective innovative policies based on greening. Value/originality. Environmental innovations should be aimed at solving tasks related to reducing the consumption of resources, controlling harmful effects on the environment, increasing the production of ecological products, reducing the costs of eliminating destructive effects of production activities. Such innovations will lead to a significant reduction in the negative impact of the economic activities of enterprises on the environment and will increase the efficiency of the use of resources, energy and materials. In addition, the ability to ensure the implementation of the waste management process will increase, which will contribute to the sustainable development of the enterprise in the long term.

Vegetation dynamics in Qinghai-Tibet Plateau (QTP) have been debated in recent decades. Most studies suggest that wetter and warmer climatic conditions would release low temperature constraints and stimulate alpine vegetation growth. Other studies suggest that climate warming might inhibit vegetation growth by increasing soil moisture depletion in the southern QTP. Most of previous studies have relied on vegetation indices derived from satellite observations to retrieve large-scale vegetation changes, and the uncertainty of vegetation indices makes it difficult to accurately characterize the vegetation trends on the QTP. Here, we developed a deep learning algorithm in the Google Earth Engine (GEE) platform to accurately map the land use/cover change (LUCC) on the QTP, and then infer vegetation gain and loss and their drivers during the period 1988–2018. The vegetation on the QTP experienced rapid greening, which was dominated by transitions from bareland to alpine grassland (27.45 × 104 km2) and from alpine grassland to alpine meadow (17.43 × 104 km2) during 1988–2018. Furthermore, although human activities influence vegetation succession at the local scale, the dominant influencing factors affecting vegetation greening on the QTP are precipitation (q-statistic = 23.87 %) and temperature (q-statistic = 11.01 %). A 30-year time series analysis clarified the specific dynamics of vegetation on the QTP, thus contributing to the understanding of the response mechanisms of alpine vegetation under climate change and providing a reference for the formulating of reasonable ecological protection policies and human development strategies.

The article analyzes the ecological condition of the soil and identifies the main problems of the environmentalization of land use in Ukraine in the case of the Kharkiv region. Deterioration of the ecological condition of agricultural land, weakening of their erosion resistance, violation of the optimal structure of land, reduction of the content of humus and basic nutrients lead to a decrease in land productivity. In general, the current state of environmental safety of land is quite unsatisfactory, so it significantly reduces the quality and volume of agricultural production. The analysis of the situation and the forecast of the efficiency of soil fertility show that due to the sharp decrease in the application of organic and mineral fertilizers, insufficient implementation of forest reclamation, and anti-erosion measures, degradation processes have intensified in all areas. The problem with the balance of nutrients has become more acute, the acidity of the soil solution is increasing, the humus content is reducing, and the intensity of erosion processes has significantly increased. The main tasks of the environmentalization of agricultural land use involve measures for increasing soil fertility by limiting the use of intensive chemicalization of agriculture; measures for the application of the organic fertilizer to ensure a deficit-free balance of humus in the soil; measures for mechanization, chemicalization, land reclamation using the latest methods; anti-erosion measures and the use of new methods of tillage, liming, soil, and minimization of tillage. Thus, to ensure the formation of environmentally friendly agricultural land use, an important condition is the creation of a scientifically sound structure and optimization of the ratio of productive (arable land) and environmentally friendly (hayfields, pastures, wooded areas) land use. The main environmentally friendly elements of this structure include agro-ameliorative and forest-ameliorative measures that form the ecological framework of agro-landscapes and are the basis for providing favorable agro-environmental parameters for agricultural land.

Global greening and its relationship with climate change remain the hot topics in recent years, and are of critical importance for understanding the interactions between the terrestrial ecosystem carbon cycle and the climate system. China, especially north China, has contributed a lot to global greening during the past few decades. As a water-limited ecosystem, human activities, not precipitation amount, were thought as the main contributor to the greening of north China. Considering the importance of precipitation event characteristics (PEC) in the altered precipitation regimes, we integrated long-term normalized difference vegetation index (NDVI) and meteorological datasets to reveal the role of precipitation regimes, especially PECs, on vegetation growth across temperate grasslands in north China. Accompanied with a significantly decreased growing season precipitation (GSP), NDVI increased significantly in the largest area of the temperate grasslands during 1982–2015, i.e., greening. We found that 28.44% of the area was explained by PECs, including more heavy or extreme precipitation events, alleviated extreme drought, and fewer light events, while only 0.92% of the area was associated with GSP. NDVI did not always increase over the 30 years and there was a decrease during 1996–2005. Taking afforestation projects in desertified lands into account, we found that precipitation, mainly PECs, explained more the increase and decline of NDVI during 1982–1995 and 1996–2005, respectively, while an equivalent explanatory power of precipitation and afforestation projects to the increase in NDVI after 2005. Our study indicates a possible higher productivity under future precipitation regime scenario (e.g., fewer but larger precipitation events) or intensive afforestation activity, implying more carbon sequestration or livestock production of temperate steppe in the future.

Introduction: The dynamics of terrestrial vegetation are shifting globally due to environmental changes, with potential repercussions for the proper functioning of the Earth system. However, the response of global vegetation, and the variability of the responses to their changing environment, is highly variable. In addition, the study of such changes and the methods used to monitor them, have in of themselves, been found to significantly impact the findings.Methods: This research builds on a recently developed vegetation persistence metric, which is simple to use, is user‐controlled to assess levels of statistical significance, and is readily reproducible, all designed to avoid these potential pitfalls. This study uses this vegetation persistence metric to present a global exploration of vegetation responses to climatic, latitudinal, and land‐use changes at a biomes level across three decades (1982–2010) of seasonal vegetation activity via the Normalized Difference Vegetation Index (NDVI).Results: Results demonstrated that positive vegetation persistence was found to be greater in June, July, August (JJA), and September, October, November (SON), with an increasing vegetation persistence found in the Northern Hemisphere (NH) over the Southern Hemisphere (SH). While vegetation showed positive persistence overall, this was not constant across all studied biomes. Overall forested biomes along with mangroves showed positive responses towards enhanced vegetation persistence in both the northern hemisphere and southern hemisphere. Contrastingly, desert, xeric shrubs, and savannas exhibited no significant persistence patterns, but the grassland biomes showed more negative persistence patterns and much higher variability over seasons, compared to the other biomes. The main drivers of changes appear to relate to climate, with tropical biomes linking to the availability of seasonal moisture, whereas the northern hemisphere forested biomes are driven more by temperature. Grasslands respond to moisture also, with high precipitation seasonality driving the persistence patterns. Land-use change also affected biomes and their responses, with many biomes having been significantly impacted by humans such that the vegetation response matched land use and not biome type.Discussion: The use here of a novel statistical time series analysis of NDVI at a pixel level, and looking historically back in time, highlights the utility and power of such techniques within global change studies. Overall, the findings match greening trends of other research but within a finer scale both temporally and spatially which is a critical new development in understanding global vegetation shifts.

Acceleration of economic processes in the world necessitates a rapid response to change, which when considering the transition to greening the economy should be reflected in the country’s energy policy. The object of research in this article is the fuel and energy sector of the world, and the subject of research - energy policy. The purpose of the scientific article is to assess the development trends of the fuel and energy complex of Ukraine in modern conditions and identify key trends in its development; determination of the main directions of energy policy and diplomacy of the country in the conditions of world economy’s greening. Research methods used: method of analysis, synthesis, systematization, comparison, abstract-logical method, statistical methods of research of economic processes. The main results were: determination of fuel reserves of Ukraine and its natural resource potential; analysis of final energy consumption and identification of trends in the level of energy intensity of GDP; assessment of the electricity generation structure in Ukraine and changes in the share of renewable energy sources; establishing ways to encourage greening of industry and prospects for implementing an environmental approach; determining the directions of energy policy and diplomacy of Ukraine in the context of the world economy’s greening. Thus, in modern business conditions, an important condition for the effective functioning of any economic system has become flexibility and the ability to quickly adapt to market conditions. Therefore, the development of an extensive system of tasks of the state’s energy strategy with those developed in accordance with the realities of a particular management system is the key to successful energy policy. And establishing cooperation in the energy sector will allow us to adopt the experience of developed countries and integrate into the European and global energy community. The ecological vector of energy systems development has been an integral trend for many years and will soon become a constant for the effective development of the country. Therefore, the implementation of preventive measures to green economy is an urgent issue of Ukraine's energy policy.

Elaboration of steps for the strategic management of environmentally sound business solutions is essential for achieving sustainable development goals in Ukraine. Although strategic directions for decarbonization of the transport sector have already been developed at the national level, effectiveness of sustainable decision-making is closely related to the greening initiative on the local level. The purpose of the paper is to form a framework of greening strategy and sustainable decision-making for transport companies that is based on the necessity to reduce emissions. The research findings are obtained using the systems analysis, SWOT analysis, and cost-benefit method. The paper proves that choosing biogas (methane) as a main transport fuel is a viable and cost-effective initiative and can be used as a financial ground for the company’s strategic formation process that involves both tactical and organizational dimensions. The analysis results also showed threats and opportunities for greening based on switching transport companies to biogas and requiring steps of governmental support in developing biogas station networks. According to the green course, this study also reveals the possibility of establishing strategic management due to an authority delegation map between services and top management of a transport company. The study has made it possible to improve strategic management of a transport company by developing an optimal scheme of interaction between stakeholders and departments in strategic leadership for greening. AcknowledgmentThis study is a part of the Scientific Project “Modeling the Transfer of Eco-Innovations in the Enterprise-Region-State System: Impact on Ukraine’s Economic Growth and Security” (№ 0119U100364), which is financed by the state budget of Ukraine.On behalf of Zuzana Juhaszova’s contribution, this paper was supported by the Slovak Research and Development Agency under the contract No. APVV-16-0602 Enhancement of the relevance of the accounting data in the SR – from expenses to value.

Abstract Evergreen dwarf shrubs respond swiftly to warming in the cool and dry High Arctic, but their response in the warmer Low Arctic, where they are expected to be outcompeted by taller species under future warming, remains to be clarified. Here, 12,528 annual growth increments, covering 122 years (1893–2014), were measured of 764 branches from 25 individuals of the evergreen dwarf shrub Cassiope tetragona from a Low‐Arctic erect dwarf‐shrub tundra site in western Greenland. In addition, branch initiation and mortality frequency time series were developed. The influence of seasonal climate and correspondence with fluctuations in regional normalized difference vegetation index (NDVI), a satellite‐proxy for vegetation productivity, were studied. Summer temperatures were the main driver of growth, while winter temperatures were the main non‐summer‐climate driver. During past and recent warm episodes, shrub growth diverged from summer temperatures. In recent decades, early summer precipitation has become the main growth‐limiting factor for some individuals, likely through micro‐topography‐determined soil moisture availability, and more than half of the shrubs studied became irresponsive to summer temperatures. There was correspondence between climatic drivers, C. tetragona growth and branch initiation frequency, and satellite‐observed vegetation productivity, suggesting the area's shrub‐dominated tundra vegetation is limited by similar climatic factors. Winter warming events were likely the predominant cause of branch mortality, while branching increased after years with poor growth and cooler‐than‐average summers. These findings show that the erect dwarf‐shrub tundra in the Low Arctic has already and will likely become decreasingly temperature‐ and increasingly moisture‐limited and that winter warming supports shrub growth, but increased extreme winter warming event frequency may increase branch mortality and vegetation damage. Such counter‐acting mechanisms could offer an explanation for the vegetation stability observed over large parts of the Arctic.

Landscaping is making visual improvements to academic institutions, urban and other private organizations with plants and attractive materials. People all over the world are attracted to green and beautiful landscapes which initiate them to be happy and creative. Especially students in higher educational institutions who spend much of their time focused on their studies need of clean, green and attractively well-designed landscape in their campus. So far data on plant species composition and perception of university towards landscape work is lacking. With this understanding, the study was conducted to investigate plant species composition and community perception towards landscaping work executed at Hawassa University’s main campus using questionnaires, interviews, observation and group discussion methods. In addition, vegetation data were collected using systematic sampling method. In the study, 221 respondents were drawn from academic staff, administrative workers and students using random sampling method. Key informants were selected using purposive sampling method. In order to identify the plant species, systematic sampling along the transect line was employed. Twelve (12), 40m X 40 m (i.e. 1600 m2) area quadrat plots were laid and all the plants species in the quadrats were collected and identified. The distance between each transects and quadrat was 200 m and 100m, respectively. 52 plant species with 44 genera and 29 families were recorded. The study showed that, the most dominant family was Fabaceae with 9 species followed by Cupressaceae as well as Moraceae with 4 species each respectively. The results revealed that, campus landscaping work was the most significantly important and made the campus more attractive by plantation (61.1%), landscaping (27.1%) and walkways (5.7%). Plantation could also modify the micro-climate of the campus environment (94.3%) due to the plants photosynthesis process which produces O2 and takes in Co2 from the atmosphere. In general educational institutions landscaping need to be encouraged to enhance the teaching-learning process, and to make the working environment attractive. A great educational environment is guided by the most powerful teacher of all, nature itself

Vegetation greenness is one of the main indicators to characterize changes in terrestrial ecosystems. China has implemented a few large-scale ecological restoration programs on the Qinghai-Tibetan Plateau (QTP) to reverse the trend of ecosystem degradation. Although the effectiveness of these programs is beginning to show, the mechanisms of vegetation degradation under climate change and human activities are still controversial. Existing studies have mostly focused on changes in overall vegetation change, with less attention on the drivers of change in different vegetation types. In this study, earth satellite observation records were used to robustly map changes in vegetation greenness on the QTP from 2000 to 2021. The random forest (RF) algorithm was further used to detect the drivers of greenness browning on the QTP as a whole and in seven different vegetation types. The results show that an overall trend of greening in all seven vegetation types on the QTP over a 21-year period. The area of greening was 46.54×104 km2, and browning was 5.32×104 km2, representing a quarter and 2.86% of the natural vegetation area, respectively. The results of the browning driver analysis show that areas with high altitude, reduced annual precipitation, high intensity of human activity, average annual maximum and average annual minimum precipitation of approximately 500 mm are most susceptible to browning on the QTP. For the seven different vegetation types, their top 6 most important browning drivers and the ranking of drivers differed. DEM and precipitation changes are important drivers of browning for seven vegetation types. These results reflect the latest spatial and temporal dynamics of vegetation on the QTP and highlight the common and characteristic browning drivers of vegetation ecosystems. They provide support for understanding the response of different vegetation to natural and human impacts and for further implementation of site-specific restoration measures.

Huanglongbing (HLB), the most destructive citrus disease, is associated with unculturable, phloem-limited Candidatus Liberibacter species, mainly Ca. L. asiaticus (Las). Las is transmitted naturally by the insect Diaphorina citri. In a previous study, we determined that the Oceanian citrus relatives Eremocitrus glauca, Microcitrus warburgiana, Microcitrus papuana, and Microcitrus australis and three hybrids among them and Citrus were full-resistant to Las. After 2 years of evaluations, leaves of those seven genotypes remained Las-free even with their susceptible rootstock being infected. However, Las was detected in their stem bark above the scion-rootstock graft union. Aiming to gain an understanding of the full-resistance phenotype, new experiments were carried out with the challenge-inoculated Oceanian citrus genotypes through which we evaluated: (1) Las acquisition by D. citri fed onto them; (2) Las infection in sweet orange plants grafted with bark or budwood from them; (3) Las infection in sweet orange plants top-grafted onto them; (4) Las infection in new shoots from rooted plants of them; and (5) Las infection in new shoots of them after drastic back-pruning. Overall, results showed that insects that fed on plants from the Oceanian citrus genotypes, their canopies, new flushes, and leaves from rooted cuttings evaluated remained quantitative real-time polymerase chain reaction (qPCR)-negative. Moreover, their budwood pieces were unable to infect sweet orange through grafting. Furthermore, sweet orange control leaves resulted infected when insects fed onto them and graft-receptor susceptible plants. Genomic and morphological analysis of the Oceanian genotypes corroborated that E. glauca and M. warburgiana are pure species while our M. australis accession is an M. australis × M. inodora hybrid and M. papuana is probably a M. papuana × M. warburgiana hybrid. E. glauca × C. sinensis hybrid was found coming from a cross between E. glauca and mandarin or tangor. Eremocitrus × Microcitrus hybrid is a complex admixture of M. australasica, M. australis, and E. glauca while the last hybrid is an M. australasica × M. australis admixture. Confirmation of consistent full resistance in these genotypes with proper validation of their genomic parentages is essential to map properly genomic regions for breeding programs aimed to generate new Citrus-like cultivars yielding immunity to HLB.

The geospatial model here presented estimates the permafrost active layer thickness (ALT) over the entire Arctic in the last 20 years, and it is based on the spatial and temporal oscillations measured by satellite-based essential variables associated with the thermal state of permafrost. The model integrates the climate and soil components, such as the land surface temperature, the snow depth water equivalent, and the mid-summer albedo, with the structural and functional descriptors of Arctic tundra biome such as the fraction of absorbed photosynthetically active radiation. The distribution of estimated ALT varies according to the vegetation classes (mosses and lichens or grasses and shrubs), but a general increase has been estimated across the whole Arctic tundra region, with rates of up to 2 cm/year.

Climate change is a major driver of cyclical and seasonal changes in alpine phenology. This study investigated how climate change affects vegetation phenology’s spatial and temporal responses on the Qinghai–Tibet plateau (QTP) from 1981 to 2020. We used the daily two-band enhanced vegetation index (EVI2) at a 0.05° spatial resolution for 1981–2014, 16-day moderate resolution imaging spectroradiometer (MODIS) enhanced vegetation index data for 2000–2020 at 250 m spatial resolution, and climate records from 106 meteorological stations from 1981 to 2020 to construct linear regression models and Mann–Kendall point test to understand the changes on QTP vegetation in response to climate change. We found that the temperature in April, July, and September controls vegetation growth, and spring precipitation (p < 0.05) influences the length of the growing period, with a partial correlation coefficient of −0.69. Over the past 40 years, temperature and precipitation changes on the QTP have not shown abrupt shifts despite the increasingly warm and dry spring climate. We observed a meridional distribution trend in the correlation between precipitation and alpine vegetation greening, browning and the length of the growing period. In regions experiencing strong warming, vegetation growth was hindered by a lack of precipitation. We conclude that climatic factors alone cannot fully explain the changing trends in vegetation phenology across the QTP.

The Common Agricultural Policy (CAP) was the last policy field to be placed under the Ordinary Legislative Procedure and its 2013 reform was the first to be decided under this rule. This article analyses how rule changes following the Lisbon Treaty have shaped policy outcomes related to ‘greening,’ i.e., making agricultural policy more environmentally friendly. Measuring the policy ambitions of amendments during the different phases of the legislative process (the processing phase within the Parliament and the negotiating phase during trilogues), we find that the European Parliament weakened the Commission’s greening proposals—but did so to support an alternative greening agenda built on different policy instruments. This means that rule change has altered the power balance between the institutions, making the Commission more dependent on the European Parliament. In the 2013 reform, this new balance of power came at the cost of greening the CAP.

Abstract Background This review updates a systematic review published in 2010 ( http://www.environmentalevidence.org/completed-reviews/how-effective-is-greening-of-urban-areas-in-reducing-human-exposure-to-ground-level-ozone-concentrations-uv-exposure-and-the-urban-heat-island-effect ) which addressed the question: How effective is ‘greening’ of urban areas in reducing human exposure to ground-level ozone concentrations, UV exposure and the ‘urban heat island effect’? Methods Searches of multiple databases and journals for relevant published articles and grey literature were conducted. Organisational websites were searched for unpublished articles. Eligibility criteria were applied at title, abstract and full text and included studies were critically appraised. Consistency checks of these processes were undertaken. Pre-defined data items were extracted from included studies. Quantitative synthesis was performed through meta-analysis and narrative synthesis was undertaken. Review findings 308 studies were included in this review. Studies were spread across all continents and climate zones except polar but were mainly concentrated in Europe and temperate regions. Most studies reported on the impact of urban greening on temperature with fewer studies reporting data on ground-level UV radiation, ozone concentrations (or precursors) or public health indicators. The findings of the original review were confirmed; urban green areas tended to be cooler than urban non-green areas. Air temperature under trees was on average 0.8 °C cooler but treed areas could be warmer at night. Cooling effect showed tree species variation. Tree canopy shading was a significant effect modifier associated with attenuation of solar radiation during the day. Urban forests were on average 1.6 °C cooler than comparator areas. Treed areas and parks and gardens were associated with improved human thermal comfort. Park or garden cooling effect was on average 0.8 °C and trees were a significant influence on this during the day. Park or garden cooling effect extended up to 1.25 kms beyond their boundaries. Grassy areas were cooler than non-green comparators, both during daytime and at night, by on average 0.6 °C. Green roofs and walls showed surface temperature cooling effect (2 and 1.8 °C on average respectively) which was influenced by substrate water content, plant density and cover. Ground-level concentrations of nitrogen oxides were on average lower by 1.0 standard deviation units in green areas, with tree species variation in removal of these pollutants and emission of biogenic volatile organic compounds (precursors of ozone). No clear impact of green areas on ground level ozone concentrations was identified. Conclusions Design of urban green areas may need to strike a balance between maximising tree canopy shading for day-time thermal comfort and enabling night-time cooling from open grassy areas. Choice of tree species needs to be guided by evapotranspiration potential, removal of nitrogen oxides and emission of biogenic volatile organic compounds. Choice of plant species and substrate composition for green roofs and walls needs to be tailored to local thermal comfort needs for optimal effect. Future research should, using robust study design, address identified evidence gaps and evaluate optimal design of urban green areas for specific circumstances, such as mitigating day or night-time urban heat island effect, availability of sustainable irrigation or optimal density and distribution of green areas. Future evidence synthesis should focus on optimal design of urban green areas for public health benefit.
