The delineation of urban growth boundary (UGB) can reasonably guide the direction of urban development and effectively restrain urban sprawl. From the perspective of coordinated development, this paper combined the multi-objective land use suitability evaluation method and the PLUS model to define the rigid UGB of the great Nanchang metropolitan area and the elastic UGB under three scenarios of natural growth, policy constraints and coordinated development. It is found as follows. ➀ The spatial distribution of multi-objective land use suitability presents the characteristics of differences, overlaps and crosses. The overlapping area of the most suitable areas for coordinated development with the most suitable areas of agriculture and the most critical areas of ecological protection has decreased compared with the most suitable areas of urban construction. ➁ The area within rigid UGB is 35 391. 03 km², accounting for 76. 11% of the total area of the study area, which can effectively control the urban expansion of the great Nanchang metropolitan area without breaking through the red line of ecological protection and the bottom line of food security. ➂ The simulation results based on the PLUS model showed that arable land, forest land, grassland and unused land decreased, while water area and construction land increased. The expansion of construction land was the most significant, and urban expansion was effectively constrained under the coordinated development scenario, the elastic UGB under the coordinated development scenario can effectively slow down the occupation of the areas with the highest agricultural or ecological value by urban expansion, and can better optimize the urban landscape pattern. The results are helpful to guide and realize the sustainable development of the great Nanchang metropolitan area, and can also provide reference for the coordinated development of production-living-ecology space in other types of cities.

AGRICULTURAL landscape management ,URBANIZATION ,AGRICULTURAL development ,SUSTAINABLE development ,FOOD security - Abstract
This article generalizes the urbanization process and its impact on agricultural land use in Vietnam. The high rate of urbanization has led to a great demand for purchasing agricultural products, especially high-quality ones, and as a result, this affects agricultural development. On one hand, it offers new chances to expand the domestic market and to encourage exports. On the other hand, the conversion of agricultural land into non-agricultural land under accelerated urbanization leads to a large area of arable land being abandoned or polluted, consequently affecting food security and sustainable development. Therefore, to meet the people's food needs in the context of urbanization, it is necessary to have proper solutions to improve the efficiency of agricultural land use, such as: implementing land laws aimed at developing agricultural production in the direction of large-scale, concentrated commodities; executing land-use planning, performing agricultural production planning towards specialized cultivation with a stable term to ensure profitable investment; boosting the restructuring of the agricultural sector; developing collective and cooperative economics in agriculture; having policies to support, forecast, and search for markets for consumption and the processing of agricultural products; creating a transparent land-use rights market.

The increasing pollution of lotic ecosystems in sub-Saharan Africa, particularly in Nigeria, poses a threat to water quality, public health and biodiversity. It is therefore essential to develop appropriate tools and methods for monitoring these rivers, particularly in heavily affected areas, where these water resources are vital to the surrounding communities that are heavily dependent on them. To fill this gap, we propose to develop a multimetric index based on macroinvertebrates for the assessment of ecological quality of rivers in Niger State (NSRBI). Eighty-eight metrics were evaluated through a step-by-step statistical process (namely, range test and stability, redundancy test and relationship with abiotic variables), in which metrics that did not meet the conditions were excluded. At the end of this process, only four metrics (%Hemiptera, Diptera richness, Pielou equitability and % of very large individuals (size > 40 mm)) fulfilling all criteria were included in the index. These metrics were then scored on a continuous scale and divided into four water quality classes: "very poor", "poor", "fair" and "good". Evaluation of the performance of the index on test sites showed a correspondence of 90% between index result and environmental-based classification. Therefore, the NSRBI could be a valuable tool for monitoring and assessing the ecological conditions of rivers in Niger State and the North Central Nigeria ecoregion predominantly in urban and agricultural landscapes.

The aim of this study was to use landscape grass from species-rich orchards for biogas production, thus preserving these very valuable areas for future generations. Since these grass clippings have high lignocellulose content, the substrate has to be pretreated before being fed into the biogas digester. In this study, three different mechanical treatment processes (cross-flow grinder, ball mill and a mounted mower) were investigated and compared with untreated grass clippings. Chemical composition, specific methane yield, degradation kinetics and microscopic images were analyzed. In order to derive recommendations, the harvesting and pretreatment processes were examined in terms of energy demand, additional methane yield, and suitability of the substrate for use in biogas plants, taking into account conservation aspects. Within the pretreatment process, ball milling leads to the highest significant increase in specific methane yield of up to 5.8% and the fastest gas formation kinetics (lag time λBM: 0.01 ± 0.0 d; duration to reach half of total gas production ½M(x)BM: 5.4 ± 0.2 d) compared to the untreated variant (λUT: 1.02 ± 0.2 d; ½M(x)UT: 6.5 ± 0.2 d). A comparison of the energy required for the mechanical disintegration of the substrates with the increased yield of methane during the digestion process shows that the mechanical processing of these substrates appears to be useful. A positive energy balance was achieved for the cross-flow grinder (12.3 kWh tVS−1) and the ball mill (21.4 kWh tVS−1), while the Amazone Grasshopper left a negative balance (−18.3 kWh tVS−1), requiring more energy for substrate pretreatment than was generated as methane surplus. In summary, the pretreatment of landscape management grass is a suitable approach for utilizing agricultural residues efficiently in a biogas plant and thus contributing to sustainable energy production.

Land cover classification is one of the most common applications of remote sensing and is used for developing and modifying land management policies on agricultural landscapes to achieve conservation and economic goals, such as reducing grassland degradation and improving livestock and crop production. In this study, the grassland classification of the crown lands (public grasslands in Canada) from a newly developed remotely sensed dataset in the Prairie Province of Manitoba (i.e., the Manitoba Grassland Inventory, MGI) was assessed in terms of accuracy by comparison to non‐spatial government records. The analysis consisted of (i) converting non‐spatial records from the provincial crown land database to spatially‐defined parcels by performing parcel delineations using geographic information system (GIS) and R programming tools, (ii) summarising the MGI classification at the same spatial scale, and (iii) comparing the agreement between MGI and the crown land database. The most common land cover types identified were: forest (30%) and shrubland (25%), followed by native (10%) and tame (9%) grasslands. However, the class agreements between woody (i.e., forests and shrublands) and grassy (i.e., native and tame grasslands) vegetation classes were low between these datasets because of their spectral similarities. Based on these results, we suggest additional refinements on both sensor and ground data to improve the classification agreement between these datasets. This study is one of the first attempts to compare ground‐collected government records against a remotely sensed product in Manitoba. [ABSTRACT FROM AUTHOR]

Agriculture is the main driver of the rapid collapse of biodiversity, upon which all life on Earth, including agricultural production, depends. As we face the challenge of feeding a growing human population under a changing climate regime, the pressure on biodiversity is expected to further intensify. While the potential to expand and improve natural habitats for biodiversity conservation has been widely explored in large-scale scenarios of agricultural systems, the critical role of agricultural landscapes’ management on halting the loss of biodiversity remains unexplored at this scale. We argue that, to achieve an effective conservation of biodiversity (both natural and agricultural), the combined multivariate effects of agriculture on biodiversity must be accounted for, including its surface area as well as its management. Based on a literature review, we identified the main biodiversity pressures stemming from agriculture: land-use change, contribution to climate change, water withdrawal, pesticide pollution, nutrient (nitrogen and phosphorus) pollution, and landscape and farmscale simplification (of croplands and pastures). For each one, we proposed a critical boundary, based on reviews of studies covering a range of taxa, biodiversity metrics, and biomes, below or above which negative impacts on biodiversity are minimized or positive effects arise. Implemented simultaneously, the identified boundaries would integrate biodiversity conservation within and across farmlands and minimize agriculture’s far-reaching impacts on biodiversity. We present a framework called “agricultural boundaries for biodiversity” that will allow to explore the potential of developing agricultural systems that effectively reconcile food production and biodiversity conservation at large scales.

Tropical deforestation and forest degradation have resulted in substantial losses of goods and services and a decline in the quality of life. Agroforestry is a viable land-use option to counteract such declines in ecosystem services, including biodiversity and supporting local livelihoods. However, it is unclear how socioecological factors mediate these roles, which hinders the implementation of initiatives to conserve biodiversity. This study aimed to investigate perennial plant species composition and diversity in relation to socioecological variables and agroforestry practices in central Ethiopia. The vegetation data were collected from 243 sample farms that belonged to 81 randomly chosen households from nine kebeles. Across all practices, 92 plant species from 75 genera and 46 families were identified. Of these, 77% were native plant species, and the remaining were exotic ones. Margalef species richness and the Shannon diversity index were both significantly higher (p < 0.05) in homegardens and middle elevations. Furthermore, species richness and the Shannon diversity index were positively and significantly related to slope, farm size, farm age, and wealth status. Parklands, lowland altitude, and younger farms had the highest Simpson's evenness, whereas wealth status, farm size, and slope had no significant association with Simpson's evenness. Overall, this study showed that agroforestry serves as a refuge for native species and helps reverse species loss in natural forests. However, native species are gradually being replaced with exotic species, compromising the integrity of agricultural landscapes. Our study also emphasizes the urgent need to consider socioecological factors when examining biodiversity and planning agricultural landscape management strategies. [ABSTRACT FROM AUTHOR]

Mountainous agriculture supports 15% of the global population, but its sustainability is facing challenges with the social transition. Honghe Hani Rice Terrace System (HHRTS), China, a double world‐level heritage, performs strong resilience to challenges. Available studies on HHRTS examines its sustainability from some perspectives but lack a systemic elaboration on its sustainable mechanism. This study extensively examines the literature on HHRTS and offers a comprehensive analysis of its sustainability. The findings suggest that mountainous agricultural sustainability depends on the support from relatively enough water and land resources and diverse employment based on these resources (economic sustainability), the environmental stability based on reasonable landscape structure, rich biodiversity and ecological farming methods (environmental sustainability), and social stability based on the well‐developing social structure, efficient management system, and relevant cultural restraint and guidance (social sustainability) as well as the dynamic interaction among the three dimensions. Among them, traditional knowledge and cultures play a positive role in maintaining the stability of terraced landscapes, but their role is weakening with industrialization and urbanization. This study provides a systemic explanation of a dynamic evolution mechanism that the economic and social factors drive local people to maintain a mountainous agricultural system from the agricultural society to the industrial society based on the theory of planned behavior. This study also provides abundant local knowledge, experiences, and an analytical framework for reconstructing a sustainable mountainous agricultural system in the socio‐economic transformation stage.

Background: One common renewable energy source for substituting fossil sources is photovoltaic (PV) systems. However, installing PV systems in agricultural areas can lead to competition with other land uses. These projects, therefore, often encounter problems with social acceptance in affected communities. Especially from the perspective of nature conservation targets, conflicts can arise. These potential differences are still under-researched but represent important knowledge for the societally broadly accepted design of such facilities and their contribution to energy transformation. In this paper, we investigate the perspectives of nature conservationists on PV in the region of Brandenburg, Germany. We comparatively analyse attitudes towards ground-mounted photovoltaics (GM-PV) and agrophotovoltaics (APV). APV combines energy supply and agricultural production on the same land and could thus be a possible solution for mitigating land-use conflicts. Results: We investigated the degree of local acceptability and positive and negative influencing factors through a qualitative text analysis of ten interviews with local representatives and position papers by Nature Conservation Associations. Our findings show a growing consensus around basic assumptions of the need for renewable energies, the prioritised support for PV systems on rooftops over the installation on agricultural land (GM-PV and APV), and the necessity for PV systems to be compatible with nature conservation objectives. Regarding specific site decisions on agricultural land, we find diverging attitudes when comparing the content of position papers and the responses of interviewees. The interviewees advocate taking into account local interests and specific regional conditions, the effects of PV systems on the local environment, and the need for distributional justice. Large-scale plants are locally less accepted than smaller ones and there is a more open attitude towards the expansion of APV than of GM-PV on agricultural land. However, a range of concerns regarding consequences for landscape and biodiversity persists, and further research and clarification is required to address these issues. Conclusions: We conclude that basic ecological standards and the demands of local stakeholders and interest groups should be taken into account when planning, implementing and reviewing PV projects in the future.

Agricultural practices have a significant impact on stream water quality in rural landscapes; however, there is still little empirical evidence of how different types of cultivation alter the hydrochemistry of running water. Thus, the current study explored the spatial dynamics of selected ion concentrations and their land cover dependence in lowland agricultural catchments. From November 2021 to October 2022, water samples were collected from 30 sites located across small tributaries of the rivers Bzura, Pilica, and Radomka for chemical analysis of their NO
3 , NO2 , NH4 , Ca, Mg, K, Na, As, Ba, Sr, and V concentrations. The results indicated a clear spatial heterogeneity of water quality, related to lithology and dominant land cover evaluated with the CORINE Land Cover 2018 dataset. Overall, sites representing agricultural land promoted increased concentrations of major and trace elements, while those with pepper cultivation were additionally contaminated with NO3 and NO2 . The correlation performance for nitrogen compounds was the highest for narrower buffer zones, which was not documented for major and trace elements, which were linked more strongly with land cover at larger scales. Such new insights into the water quality dynamics of lowland agricultural catchments, being a simultaneous reflection of lithology, agricultural practices, and several municipal impacts, have significant implications for appropriate water management in rural landscapes.

In this research, we introduce a groundbreaking method for the classification of Historical Architectural Heritage (HAH) resources, with a particular focus on their integration within agricultural landscapes. Employing a sophisticated blend of Geographic Information System (GIS) technologies and advanced feature fusion techniques, our approach uniquely emphasizes the interaction between architectural heritage and agricultural land use. The methodology commences with the extraction of historical and agricultural attributes from HAH sites, leveraging sensor fusion technology to capture the nuances of their relationship with surrounding farmlands. We categorize these resources into three distinct classifications: 'agriculturally integrated', 'agriculturally independent', and 'absent agricultural linkage'. This innovative classification is sensitive to the architectural merits of the HAH resources and their agricultural context, shedding light on the symbiotic interplay between heritage sites and rural agrarian practices. A pivotal component of our approach is integrating agricultural spatial features in the classification process. This involves analyzing HAH sites' proximity, dependency, and interaction with adjacent agricultural lands, thereby enriching the heritage classification with an agro-centric perspective. The effectiveness of this methodology has been rigorously tested in the agricultural regions of Hubei Province, China, demonstrating enhanced precision and depth in the classification of HAH resources within an agricultural framework. The proposed method stands out for its cost-effectiveness and practicality, offering a novel tool for the management and preservation of HAH resources in agricultural settings. It bridges the often-overlooked gap between architectural heritage conservation and agricultural land management, thus paving the way for sustainable development in rural landscapes. This research contributes significantly to both theoretical and applied aspects of heritage conservation, promoting an integrated approach that respects and upholds the intrinsic value of agricultural landscapes in historical heritage management.

The series Strawberries in Winter provides a visual representation of the evolving agricultural landscape, highlighting the impact of modern agricultural practices within the context of capitalism. In the current state of agriculture, where the demands of supermarkets and consumers for year-round availability, consistent quality and low prices have led to significant changes in farming practices. The pressure to produce more on the same land, utilizing advanced technology and scientific advancements, has led to the expansion of farms, increased mechanization, and a shift away from the traditional rhythms of nature. The imagery of Strawberries in Winter symbolizes this dissociation from natural cycles and the disconnection from traditional modes of agriculture. In essence, it depicts a changed agricultural landscape that is shaped by profit-driven practices, consumer demands, a growing population and technological advancements, which collectively contribute to the reimagining of nature and reality to fit within the constraints of a capitalist framework.

Context: Maintaining a balance between semi-natural habitats and arable land is not always feasible for farmers. The promotion of biological control agents can be addressed through management at farm or field level, and/or by deploying lower intensity, biodiversity-friendly practices which can act either directly or indirectly through their effect of the plant community. Objectives: We studied the effects on cereal aphids and their parasitoids of agricultural management at field and landscape levels. We tested the effect of organic and conventional farming, and of the within field characteristics, on the cereal aphid-parasitoid community, across a gradient of organic farming aggregation and of percentage of arable land. Methods: In spring 2015, we sampled aphid populations in 30 cereal fields in five agricultural areas in Catalonia (Spain) with contrasting levels of organic farming aggregation. In each field, we also assessed weed and crop cover. As landscape variables, we calculated the Percentage of Agricultural Land (PAL) and the Percentage of Organically Managed Land (POML) in a 500-m buffer around each field. We sampled cereal tillers 3 m from the field edges and collected all aphids detected. In addition, we reared mummies (parasitized aphids) until they hatched. Results: Our results show that management at landscape level has significant effects on parasitism rates: a higher proportion of surrounding fields under organic management increased the amount of parasitism, as did less agricultural land cover. On the other hand, aphid populations were mainly affected by two in-field factors, namely, crop density and crop variety. Differences in weed communities did not seem to have any effects on either aphids or parasitoids. Conclusions: Rather than concentrating on the individual management of fields, a coordinated implementation of organic farming at landscape level would seem to be a much better strategy for improving the biological control of aphids.

Context: Agricultural activities constitute the most significant source of nitrate pollution, posing a threat to water quality and ecosystem services. The Nitrates Directive is an integral feature of the Water Framework Directive, which seeks to reduce nitrate pollution from agricultural sources. Directive compliance has proven to be problematic for every Member State in fulfilling their respective implementation duties. Objectives: The research focuses on the nitrate management discourse within agricultural landscapes of Poland and provides a governance capacity framework to understand how social factors shape local implementation performance. The case study examines how the social factors of social capital and street-level bureaucrats constrain or enable stakeholder agency within agricultural landscapes. Methods: The empirical investigation utilizes a multi-method assessment, including a survey categorizing social capital levels among 31 Polish farmers, interviews with nine stakeholders, and a literature review. Results: The findings demonstrate how differentiated social capital levels are a result of complex social dynamics within the nitrate management discourse. Achieving policy objectives rests on stakeholder interactions in their capacity to navigate myriad changes and translate policy messages into practical actions. Due to low social capital levels exhibited by farmers and limited agency of street-level bureaucrats, overall capacity for effective nitrogen management in Polish agricultural landscapes is constrained. Conclusions: Overall, the study contributes new insights in identifying how social factors affect the ability of Member States to fulfill implementation obligations. Further, the study discusses the influence of social factor interplay upon actor agency and subsequent policy relevance amidst changing agri-environmental landscapes. [ABSTRACT FROM AUTHOR]

Since the Green Revolution, the management of agrochemicals has become a cornerstone of agriculture, allowing it to expand over terrestrial ecosystems previously deemed unsuitable for cultivation. Such expansion altered the connectedness of aquatic habitats to organisms with complex life cycles by increasing the number of temporary ponds in interfluves. Here, we investigate how spatial isolation and intensification in the use of agrochemicals can interact to increase or decrease the permeability of agricultural fields to these organisms by affecting community structure in temporary ponds.We carried out a field experiment that simulates realistic scenarios of agrochemical contamination at different levels of spatial isolation. We constructed 45 1200‐L artificial ponds in a Savanna landscape in Brazil at three distances from a source wetland (30, 120, and 480 m). The ponds were spontaneously colonized by aquatic insects and amphibians and treated with no agrochemicals (control), fertilizers (as in managed pastures) or fertilizers and a single pulse of the insecticide fipronil and the herbicide 2,4‐D (as in sugarcane fields) following realistic dosages and application schedules.Communities treated only with fertilizers generally exhibited a higher abundance of aquatic insects at the peak of the rainy season, suggesting that fertilization caused bottom‐up effects. However, because low spatial isolation and fertilization favoured different predatory taxa, their insect prey eventually became less abundant in less isolated fertilized ponds. Communities treated with fertilizers and pesticides diverged strongly from other treatments after the application of the insecticide, when a decrease in insect abundance indirectly benefitted amphibian populations. In this case, spatial isolation delayed the recovery of the abundance of several herbivore and detritivore insects in isolated ponds.Synthesis and applications. These results have direct consequences for the emergence of insects and amphibians, possibly affecting important ecosystem services. Such consequences can be controlled by avoiding agrochemical contamination at the peak of most taxa reproductive season or through changes in spatial isolation by deliberately constructing wetlands in interfluves. In all cases, the effects of agrochemicals and isolation must be addressed jointly for a successful management of biodiversity in agricultural landscapes. [ABSTRACT FROM AUTHOR]

Sand mining activities on agricultural land and rivers in Bambang Village, Wajak District, Malang Regency, have been ongoing for a long time. The sand mining activities on private agricultural lands, besides being illegal, also damage the land and the environment. In addition, these sand mining activities are also unsustainable. This study aimed to analyze and formulate sustainable alternative livelihoods of sand miners on agricultural lands in Bambang Village, Wajak District, Malang Regency, based on local resources. The study method was carried out using a combination of case studies and survey methods, accompanied by indepth interviews and field observation. The in-depth interviews were conducted by interviewing 60 respondents for key informants from miners, farmers, many stakeholders, and experts that were selected purposively. The data obtained were analyzed using a multi-criteria analysis (MCA), namely PROMETHEE (Preference Ranking Organization Methods for Enrichment Evaluation) program to formulate sustainable alternative livelihoods. The results showed that the best alternative sustainable livelihood at this location is agriculture. The second best alternative sustainable livelihood is ecotourism, the third is animal husbandry, and the fourth is informal sectors based on local resources. The government should support the development of agriculture, ecotourism, animal husbandry, and the informal sectors in the village. [ABSTRACT FROM AUTHOR]

An increase in the built-up area occurred in Batu City by 554.4 ha or 2.78%, and a decrease in agricultural land by 341.1 ha occurred in 2008-2018. If the Batu City government does not pay attention to the availability of environmental services or consider the geomorphological conditions of Batu City for developing settlements. In that case, it will have an environmental impact. The environmental problem in Batu City during the 2009-2019 period was an increase in greenhouse gases by 0.75% per year. Batu City is located in a hilly area. It is necessary to explore land capability in Batu City so that land use planning follows its environmental services and is sustainable. This study aimed to determine the land capability for settlements in Batu City based on the Regulation of the State Minister for the Environment Number 17 of 2009 concerning Guidelines for Determining Environmental Supporting Capacity in Regional Spatial Planning. This study used a geographic information system (GIS) and ArcGIS 10.8 software. The method used was overlapping soil texture, slope, drainage, effective soil depth, erosion, and flood potential maps. Batu City has a slope of 30-45% and a total area of 6,581.03 ha, or 33% of the area of Batu City. The largest erosion rate reached 10,326.33 ha or 52% of the total area of Batu City. Erosion occurs on land used for agriculture or moorland. Soil protection and erosion control measures are strongly recommended. The area around Batu City, 1,174.28 ha, experienced considerable erosion, and 2,631.62 ha of land in Batu City is used for settlements. Land capability analysis can determine the starting point or basis for settlement land management in Batu City, which has a slope of more than 15%. There are only 461.9 ha of land management for settlement which follows the regional spatial planning and land capability in Batu City, spread over three different districts. [ABSTRACT FROM AUTHOR]

Grassland is grouped into temporary, permanent, and rough grazing types in the United Kingdom (UK), making up more than 60% of the national agricultural land area. It provides avenues for grazed fodder or ensiled forage contributing a large proportion of the diets consumed by cattle and sheep. The official agricultural census data in 2011 to 2020 showed that, on average, UK cattle and sheep farming can produce meat to satisfy 83.3 and 100.8% of domestic cattle beef and sheep meat consumption levels, respectively. Out of the large agricultural census datasets, we used the populations of cattle and sheep, as well as the UK definition of a standard livestock unit (SLU), to normalise the respective herd populations into a total standard livestock unit (TSLU). We then used the annual domestic meat production in dressed carcass weight to calculate cattle and sheep meat productivity per SLU. Using the potential herbal dry matter yields per year and areas of the different grassland types across the UK, the potential total available pasture feed was calculated. This potential production of herbal biomass was translated into the potential carrying capacity expressed in a TSLU. This total potential carrying capacity was partitioned into cattle and sheep sectors so that the routes of pasture-based-only options with which to produce ruminant meat to meet the current UK domestic consumption demands were assessed. The estimated mean potential annual pasture forage feed in 2011–2020 was approximately 82.0 million (M) metric tonnes (t), which can be translated into a potential carrying capacity of 17.9 M SLUs compared with the current mean 9.36 M SLUs in the survey data of the UK. With the ratio of sheep to cattle at 8.2:25 in the national TSLU, the UK national demands at present consumption levels of cattle and sheep meat can be arithmetically met with pasture grass utilisation rates at or above 65% and 50% by cattle and sheep farming systems, respectively.

The methods of developing photovoltaics on agricultural land in France are still very poorly documented and this article offers a contribution to understanding their implications. The authors explain how this development is taking place at the intersection of national public regulation, strategies of public and private actors, and emerging territorial dynamics. They show that the rules governing the use of land and the production of renewable energy constrain, but do not prohibit, photovoltaics on agricultural land. They identify a rule of priority for installation on artificialized spaces, but also four exceptions to the rule, all subject to interpretation processes. They then describe the strategies carried out in this context by agricultural stakeholders, public authorities and energy companies. At local levels, energy companies are looking for agricultural land taking into account the doctrines affirmed by public and agricultural stakeholders in the territories concerned. On a national scale, these companies are pleading for changes to the rules of the game, on the one hand to restrict regulatory obstacles to the installation of photovoltaics on agricultural land, and on the other hand to gain recognition for the approaches they present as demanding in the combination between agriculture and energy production.

Green development is an inevitable trend in the modernization of agriculture and rural areas, and promoting the green development of agriculture has always been an important measure for China's sustainable growth. However, due to the influence of diverse regional environments and the wide range of landscapes in China, a largely agricultural country, China is facing ongoing challenges in improving the overall level of agricultural green development and narrowing regional differences, which has recently garnered worldwide attention. This study aims to measure and analyze the agricultural green development level of 30 provinces in China (Tibet, Hong Kong, Macao, and Taiwan are not included in the target areas of this research due to a lack of data). Here, we applied GIS technology, an entropy-TOPSIS (technique for order of preference by similarity to ideal solution) model, quantitative analysis methods such as global spatial autocorrelation analysis, coldspot and hotspot analysis, and a spatial Durbin model to construct measurement models and index systems, after which we performed a comprehensive spatiotemporal analysis of China's agricultural green development level. Furthermore, the present study also analyzed the factors that influence agricultural green development in China. The present study demonstrated that: (i) between 2005 and 2020, China's overall level of agricultural green development exhibited a fluctuating upward trend, with significant improvement and enhancement in most provinces. However, the overall level of China's agricultural green development remains low, and differences at the provincial level are particularly prominent, with the main regions displaying the following descending development pattern: Eastern > Central > Western regions. (ii) The level of China's agricultural green development shows clear signs of spatial aggregation, characterized by spatial dependence and heterogeneity. Although this phenomenon is gradually weakening over time, the high levels of agricultural green development in the eastern regions and low levels in the western regions are likely to persist in the near future. (iii) Green agricultural structure, technology supply, agricultural mechanization level, and arable land area are the key factors influencing China's level of agricultural green development. Among these factors, technology supply, agricultural mechanization level, and arable land area have the largest direct impact, whereas green agricultural structure has a positive spatial spillover effect on the level of agricultural green development. Technology supply has both a positive direct impact and a negative indirect impact on the level of agricultural green development. Therefore, further improving technology supply and agricultural mechanization level can directly promote China's agricultural green development. [ABSTRACT FROM AUTHOR]

The evolving customer demands have significantly influenced the operational landscape of agricultural companies, including the transformation of their supply chains. As a response, many organizations are increasingly adopting green supply chain practices. This paper focuses on the initial step of selecting a green supplier, using the case study of the Semberka Company. The objective is to align the company with customer requirements and market trends. Expert decision making, grounded in linguistic values, was employed to facilitate the transformation of these values into fuzzy numbers and subsequently derive rough number boundaries. Ten economic-environmental criteria were identified, and six suppliers were evaluated against these criteria. The fuzzy rough LMAW (Logarithm Methodology of Additive Weights) method was employed to determine the criteria weights, with emphasis placed on the quality criterion. The fuzzy rough MABAC (Multi-Attributive Border Approximation Area Comparison) method was then utilized to rank the suppliers and identify the top performer. The validity of the results was established through validation techniques and sensitivity analysis. This research contributes a novel approach to green supplier selection, employing the powerful tool of fuzzy rough sets. The flexible nature of this approach suggests its potential application in future investigations. The limitation of this study is more complicated calculations for the decision maker. However, this approach is adapted to human thinking and minimizes ambiguity and uncertainty in decision making, and in future research, it is necessary to combine this approach with other methods of multi-criteria analysis.

The Mountain Law, No. 197 of July 20, 2018, regulates the methods of protection and sustainable and inclusive development of the mountainous area through the valorization of natural and human resources, improvement of living standards, population stabilization, preservation of cultural identity, and increase in economic power at the local and national levels, all while maintaining ecological balance and protecting the natural environment. The mountainous area of Romania is considered a special, strategic, economic, social, and environmental territory of national interest. Due to limitations in the use of agricultural land caused by altitude, climate conditions, slopes, geological substrate, high costs of works, living conditions, infrastructure, business environment, access to education, and medical services, it is considered disadvantaged. Through the Mountain Law, the approval of the Program for Encouraging Activities in the mountainous area is granted, with an allocation of 1 billion euros over a period of 10 years from its entry into force, from the state budget, through the budget of the Ministry of Agriculture and Rural Development. This Program serves as a source of support for performance in the agricultural and non-agricultural sectors. There are funding programs for investments in three areas aimed at the residents of the mountainous area: Investments for the establishment of milk collection and/or processing centers; Investments for the establishment of mountain pastures; Investments for the establishment of primary collection and processing centers for forest fruits, mushrooms, and/or medicinal and aromatic plants. Beneficiaries of the investment programs can be individual authorized persons, individual enterprises, family enterprises, producer groups, agricultural cooperatives, legal entities, and legal entities engaged in agriculture and/or the food industry. Eligible beneficiaries, regardless of the type of investment they choose, must cumulatively meet the following conditions: operate in the mountainous area, access only one type of investment once throughout the entire Program period, and not have received similar support under the National Rural Development Program (PNDR) 2014-2020, including during the transition period.

Avian communities maintain ecological balance by eliminating pests, providing ecosystem services, and acting as biological indicators, thereby playing a pivotal role in conserving agricultural landscapes’ integrity and stability; thus from an environmental monitoring standpoint, assessment of bird aggregations in various landscapes is necessary. A three-year (2021, 2022 and 2023) bird survey was conducted to document the checklist, density, and diversity of bird species assemblage of agricultural landscapes in the Karnal district of Haryana, India, to obtain the richness of birds in different agricultural habitats. A total of 79 bird species from 36 families and 14 orders were recorded; two bird species (Alexandrine Parakeet and BlackHeaded Ibis) are listed as Near Threatened in the ‘IUCN’ (2010) category. Seventeen avian species with global declining population trends are present in the study area. The Passeriformes order, with 44 species, is the most diverse in the study area. In all habitats, analysis of food and feeding guilds, as well as perching activity, revealed that the insectivorous guild (29) is dominant, followed by Omnivore (25), Carnivore (11), Granivore (7), Frugivore (5), and Nectarivore (2). The results of this study indicate that, in order to enhance the quality of bird habitat in agricultural landscapes, biodiversityfriendly farming practices should be adopted. [ABSTRACT FROM AUTHOR]

GROUND penetrating radar , *ELECTROMAGNETIC induction , *AGRICULTURAL landscape management , *SOIL moisture , *WATER table , *SOIL salinity - Abstract
Information on the spatiotemporal variability of soil properties and states within the agricultural landscape is vital to identify management zones supporting precision agriculture (PA). Ground-penetrating radar (GPR) and electromagnetic induction (EMI) techniques have been applied to assess soil properties, states, processes, and their spatiotemporal variability. This paper reviews the fundamental operating principles of GPR and EMI, their applications in soil studies, advantages and disadvantages, and knowledge gaps leading to the identification of the difficulties in integrating these two techniques to complement each other in soil data studies. Compared to the traditional methods, GPR and EMI have advantages, such as the ability to take non-destructive repeated measurements, high resolution, being labor-saving, and having more extensive spatial coverage with geo-referenced data within agricultural landscapes. GPR has been widely used to estimate soil water content (SWC) and water dynamics, while EMI has broader applications such as estimating SWC, soil salinity, bulk density, etc. Additionally, GPR can map soil horizons, the groundwater table, and other anomalies. The prospects of GPR and EMI applications in soil studies need to focus on the potential integration of GPR and EMI to overcome the intrinsic limitations of each technique and enhance their applications to support PA. Future advancements in PA can be strengthened by estimating many soil properties, states, and hydrological processes simultaneously to delineate management zones and calculate optimal inputs in the agricultural landscape.

Ecuador has committed to climate change mitigation by reducing greenhouse gas emissions from anthropogenic activities, including livestock production. This sector can also contribute to mitigation by increasing carbon sequestration and storage capacity through increasing tree coverage. Although feasible, tree cover expansion would require agricultural land, creating a conflict with food production, thus appropriate areas need to be selected, and the impacts on livestock production quantified. Following water protection legislation and soil protection guidelines, we use a combination of measurements on 100 farms with land cover datasets to identify suitable areas for increasing tree coverage in livestock landscapes. Land cover classification was performed in 2 km areas around 100 livestock farms in the coastal and Amazon regions in Ecuador. Riparian zones were identified following legislation and steepland pastures identified from a slope map. Pasture in riparian areas or steeplands (slope > 15%) were considered suitable for increasing tree coverage by restoration or silvopastoral systems (SPS). The impact of forest/silvopastoral on biomass production was quantified. Overall, 855 km of rivers were studied, between 1–18% of riparian areas were classified as pastures, whilst from the 85992 ha included in the land cover classification, 41668 ha were identified as steepland, 1–28% of steepland was covered by pastures. We estimate that steepland pasture conversion into forest could offset 1.8–10% of Ecuador's annual GHG emissions from the agricultural sector, but its impacts could represent a decrease > 50% of pasture biomass production at landscape level. Transformation of riparian and steepland pastures into SPS, could deliver important carbon sequestration, with a reduction in pasture biomass production of less than 20%. [ABSTRACT FROM AUTHOR]

Rivers networks represent hierarchical dendritic habitats within terrestrial landscapes and differences in connectivity and land use influence dispersal, and consequently biodiversity patterns. We, therefore, measured variation in water chemistry and fish abundance and related these to a number of landscape characteristics (e.g., wetland, urban, wooded, and agricultural) in the River Klarälven and its 30 permanently flowing tributaries. We hypothesized that these environmental attributes would differ between tributary and main stem habitat and that these differences would be driven by landscape attributes including land use. We found considerable intertributary variation in temperature and nutrient levels, and between the tributaries and the main stem. Generally, water temperature was lower in the tributaries, whereas nutrient levels were higher in the tributaries. The lower water temperature has implications for coldwater fishes, and we found two fishes, burbot and lamprey, associated with coldwater tributaries. We also found an inverse relationship between water quality and anthropogenic land use. Protecting tributaries with low anthropogenic impact will likely become increasingly important with ongoing global warming as they can function as thermal refugia for coldwater fishes. Hence, this study underscores the need to evaluate water courses at regional scales to identify spatial refuges and ensure connectivity. [ABSTRACT FROM AUTHOR]

AGRICULTURAL landscape management ,ENVIRONMENTAL quality ,POPULATION dynamics ,HARES ,AGRICULTURAL ecology ,ANIMAL populations - Abstract
Th e European hare (Lepus europaeus) is one of the farmland specialists inhabiting agroecosystems. It is particularly sensitive to negative changes in agricultural management and landscape homogenization. Th e quality of the environment affects not only the hare population dynamics but also the behaviour of individuals, which is reflected in the variation in home range sizes. Preliminary results of the GPS telemetry monitoring in the Czech Republic revealed signifi cant differences in the home range size of hares in high-diversified farmland (18.62 ± 4.14 ha) and conventionally managed agroecosystems (129.96 ± 55.64 ha) during the spring. Th ese results demonstrate that the hare can thrive in a relatively small area, provided there are sufficient food sources and suitable shelter opportunities. However, increasing the biodiversity of the landscape can benefit not only the European hare but also other wildlife including protected birds and animals, which can respond to positive changes in the agroecosystem.

Detection of the exchange and distribution of agricultural lands allows many projects and plans to be made and interpreted correctly, such as food safety, planning, and environmental risk analysis. From this point of study in the spatial changes and distribution of agricultural land in time across Turkey were examined. CORINE Land Cover (CLC) data was used to identify agricultural land and examine changes over time. As a result of the study, it was observed that agricultural lands increased slightly from 1990 to 2018, but this increase has not always been in the form of preserving existing agricultural lands and adding existing agricultural lands. While some areas have lost their agricultural land characteristics, some areas have become agricultural land. New agricultural areas are usually realized by the transformation of forests and semi-natural areas while the agricultural areas that disappear are provided from heterogeneous agricultural areas. The Central Anatolia region stands out in the distribution of agricultural areas by region. The region with the highest concentration of agricultural land in terms of both proportion and area is the Central Anatolia region. Also, the Central Anatolia region is the region with the most intensive Non-irrigated agriculture. The area where irrigated agriculture is proportionally most made is the southeast Anatolia region. According to province-based, the provinces with more than 40% of the provincial surface area are Kırıkkale, Kırşehir, Nevşehir, Aksaray in the Central Anatolia region, Gaziantep and Şanlıurfa in the Southeastern Anatolia region, Edirne and Tekirdağ in the Marmara region. The provinces of Artvin, Tunceli, Bingöl, and Hakkari are the provinces where the percentage of agricultural land is below 10%. [ABSTRACT FROM AUTHOR]

In agricultural landscape management, the conventional top-down approaches that primarily focus on market-led responses struggle to preserve the landscape elements essential for environmental sustainability. To address this deficiency, land use and land cover change (LUCC) scenarios promote an integrated understanding of landscape dynamics and highlight the inconsistency between the compartmentalisation of the public sector ("siloisation") and the necessity for management that reflects the interdependencies of socio-ecological systems. This study investigates the extent to which the creation and dissemination of LUCC scenarios lead to modifications in the values, attitudes, and behaviours of local actors engaged in land management, giving particular emphasis to the role of these scenarios in encouraging integrated management. To accomplish this objective, we interviewed local actors who actively participated in the co-construction of the scenario narratives or learned about the scenarios during dissemination workshops. We then analysed the data via a thematic and lexicometric analysis. The findings highlighted the dual function of these scenarios as a catalyst for pre-existing political will to promote integrated management and as a tool for raising awareness about major environmental challenges. At the group level, the outcomes encompassed aspects such as basing political decisions on the results of scenarios and fostering collaboration between institutions. These outcomes were observed among the actors involved in co-constructing scenarios or those with pre-existing motivations to pursue integrated management initiatives. Additional personal outcomes included an increased awareness of environmental challenges and the consolidation of non-formalised knowledge. We argue that combining co-construction and dissemination enhances the outcomes of scenarios considerably. [ABSTRACT FROM AUTHOR]

Context: Landscape fragmentation carries the risk of habitat loss for many animal species. This may include wild boars, which are one of the main culprits of conflicts with humans, while isolated patches of forest (forest islands) scattered in the agricultural landscape may affect its ecology and the pressure on the crops. Objectives: This study aimed to understand the importance of small forest islands located in a human-dominated agricultural landscape in the ecology of wild boar. It explores what features, both of the interior and exterior of the islands, influence their use. Methods: The study area covered approximately 220,000 ha of northern Poland, where wild boar use of 200 islands distributed across the agricultural landscape was investigated. For this purpose, the method of counting pellet groups was applied on transects of a total length of 51.6 km. In order to compare the use of islands with compact forest complexes, 84 km of transects were made in the latter, divided into developmental stages and forest type. Results: Among the features of the interior of the islands, increasing cover conditions and the main species of trees (pine, spruce and alder) had a positive influence on the wild boar use. The utilization also depended on the presence of human settlements, other islands, and the type of agricultural crop around the island. When comparing island use to compact forest complexes, islands were used more often than forest regeneration sites and mature stands, but less often than pre-thickets. For the 25% most frequently used by wild boar, islands were more attractive than virtually all stand development stages in compact forest complexes. Conclusions: Due to the cover conditions provided, the occurrence of islands in the agricultural space enables wild boars to use areas more distant from compact forest complexes. This may cause the spread of damage caused by wild boars in the fields, but on the other hand it may reduce the pressure on agricultural areas in the immediate vicinity of compact forest complexes. Intensification of hunting pressure in the vicinity of islands with specific characteristics e.g. good cover conditions, considerable distance from human settlements) will increase the effectiveness of wild boar population control in the agricultural landscape and will have a limiting effect on the damage caused by this species in the fields.

This study assesses the dispersal and use of corridors by wildlife in wooded patches of an agricultural landscape in New Bussa. The study was undertaken to derive information on the species of wildlife associated with different habitat corridors in both wet and dry seasons in the area, as well as to determine their relative abundance and diversity in the area. The direct/indirect method of census was used. The data collected were analyzed using descriptive statistics (tables), and Analysis of Variance [ANOVA] was used to test if species distribution differed between habitats. The results showed that compared to the dry season, the rainy season had the greatest diversity of mammal species. In both the wet and dry seasons, there are more animal species in fencerows and hedgerows. During the two seasons, it was discovered that Agama agama, Rattus rattus of the Muridae family and Rousettus acguptiacus of the Pteropodidae family, Sciurus spermophilus, Sciurus carolinensis, and Epomophorus ganbianus were quite common in all habitat categories.. The Estrildidae family, followed by the Ardedae family, has the largest relative abundance among the various bird species. While avian species diversity in the three habitat types in the wet and dry seasons indicates substantial species diversity in all habitats, mammal species diversity between habitats was considerably low (P>0.05) in both the wet and dry seasons. Therefore, in the agricultural environment of New Bussa, all habitat corridors with representative samples of animals are valuable for wildlife conservation. [ABSTRACT FROM AUTHOR]

The spatial distribution of soil phosphorus (P) is important to both biogeochemical processes and the management of agricultural landscapes, where it is critical for both crop production and conservation planning. Recent advances in the availability of large environmental datasets together with big data analytical tools like machine learning have created opportunities for evaluating and predicting spatial patterns in complex environmental variables like soil P. Here, we apply a random forest machine learning model to publicly available soil P datasets together with nearly 300 geospatial attributes summarizing aspects of soil type, land cover, land use, topography, nutrient inputs, and climate to predict total soil P at a 100 m grid scale for the Upper Mississippi River Basin (UMRB), USA. The UMRB is one of the most intensively farmed regions in the world and is characterized by widespread water quality degradation arising from P-associated eutrophication. Although potentially complex interacting drivers determine total soil P, the predictive accuracy of our random forest model was relatively high (R2 = 0.58 and RMSE = 129.3 for an independent validation dataset). At the regional scale represented by our model, the variables with the greatest comparative importance for predicting soil P included a combination of soil sample depth, land use/land cover, underlying soil physical and geochemical properties, landscape features (such as slope, elevation and proximity to the stream network), nutrient inputs, and climate-related factors. An important product of this research is a fine-scale (100 m) raster data layer of predicted total soil P values for the UMRB for public use. This dataset can be used to improve conservation planning and modeling efforts to improve water quality in the region. [ABSTRACT FROM AUTHOR]

Large-scale farming by agricultural land transfers has been increasingly promoted in recent years, but the possible impacts on crop production, especially cash crops, and soil acidification remain unclear. This study obtained data for 110 banana plantations in Long'an County, China, and categorized them into small (< 0.67 ha), medium (0.67-6.7 ha), and large (> 6.7 ha) to determine banana cultivation, nutrient management, and soil acidification rates on farms of the three sizes. Banana yield per unit area significantly increased with increased farm size, and large farms had the highest average yield (48.9 t·ha-1) with the least variation. Despite a significant increase in organic fertilizer and base cation inputs, nitrogen (N) surplus did not differ significantly with increasing farm size. With large farms, actual soil acidification rate was significantly lower by 19.1 to 24.0 keq·ha-1·yr-1; however, potential soil acidification rate increased with increased overuse of phosphorus. Overall, larger banana plantations used fewer mineral N fertilizers reducing the rate of soil acidification and increasing the H+ buffering provided by organic fertilizers. It is concluded that larger farms deliver the dual benefits of higher, less variable banana yield and mitigation of soil acidification by substituting organic N for mineral N fertilizers, supporting sustainable soil management and food production.

Context: Understanding what characteristics influence retreat-site selection by fauna is critical for both habitat management and species conservation. Despite the documented ecological values of surface rocks, there is limited knowledge of the attributes of surface rock that contribute to their use in agricultural landscapes or during winter months when reptiles are brumating, activity patterns are reduced, and sheltering individuals are most vulnerable to disturbance. Objectives: We surveyed reptiles sheltering beneath surface rocks in grazing farms in south-eastern Australia to address two questions: (i) What landscape factors influence the occurrence of reptiles over austral winter? (ii) What physical and thermal factors influence retreat-site selection? Methods: We surveyed 14 sites, with three plots per site, stratified across a gradient of canopy cover. We measured landscape attributes of surveyed sites and thermal and physical characteristics of individual surface rocks to quantify relationships between the occurrence of reptiles in the landscape and the properties of retreats selected. Results: We found that relatively small patches of surface rock can support high reptile numbers, with density estimates up to of 208 individuals per hectare. Reptile abundance was positively associated with increased elevation and limited canopy cover. Reptiles selected smaller rocks with high surface area to volume ratio, were minimally embedded in the soil, and rocks supporting few invertebrates. Conclusions: Conserving cryptozoic reptiles in agricultural landscapes can be enhanced through the appropriate management and retention of surface rock. We discuss implications for reptile conservation and surface rock management in agricultural landscapes. [ABSTRACT FROM AUTHOR]

The use of neighborhood search techniques to address a practical issue faced by agricultural investors is examined in this study. The problem is named as agricultural land investment problem with precedence constraints and it has an essential impact on agriculture issues. The tackled problem can be viewed as a variant of the well-known classical 0-1 knapsack problem where precedence constraints are imposed on pairs of items. Precedence constraints take into account a precedence relation between items. This paper first simulates the considered problem as precedence constraints knapsack problem and presents a mathematical representation model. Then, an iterative three-stage neighborhood search method is proposed for optimizing the problem. The proposed method consists of three stages. First stage applies a greedy procedure in order to construct a feasible solution. Second stage applies local search procedures in order to enhance the quality of the solutions at hand. Third and last, in order to broaden the search space, a random neighborhood destruction approach is introduced. Finally, the effectiveness of the suggested approach is assessed and contrasted with the outcomes obtained by greedy and local search techniques. The presented method is competitive and efficient since it produces excellent solutions in a reasonable amount of time. [ABSTRACT FROM AUTHOR]

Digital Twin is conceived as a tool designed to monitor the effects of climate change and human activity on a global scale by integrating Earth Observation with local information. When applied to Cultural Heritage and built environment, this concept requires a detailed analysis to decode the richness of sites and context, highlighting specific local features. This paper aims to contribute to the preservation of the complexity of natural, agricultural, and designed landscapes, including the architectural scale. The case study is the Villa Arconati site in Castellazzo of Bollate, in the metropolitan-peri-urban area of Milan, which is a monumental 16th Century complex, with a significant historical and cultural value and an exceptional green biomass resource in a densely built area. The analysis is carried out at two scales, which complement each other: (i) an environmental-scale study that uses historical maps and the Normalized Difference Vegetation Index (NDVI) analysis from the last two decades to monitor biodiversity transformations and highlight the level of conservation; (ii) a local-scale multi-sensor survey, which uses experimental equipment, such as a spherical camera, to extract 3D vegetation models - referred to historical views - to set conservation criteria of the landscape layout. The multi-temporal-scale analysis helps to define sustainable future management practices (such as FAR and PAS) and raises awareness among the community and the visitors about the importance of preserving both the historical and architectural value and the site's biodiversity.

A new comprehensive water, energy, food, greenhouse gas (WEFG) nexus index was developed to capture the interrelationships between them. A total of 11 indicators were applied to consider the interplay of resources consumption, productivity, economic issues, and carbon emission as one of the most critical issues regarding sustainable agricultural development. The proposed WEFG index was evaluated for crop pattern optimization. The results showed that the WEFG ranged from 0.162 to 0.658, which were calculated respectively for almonds and rice due to their energy consumption and carbon emission levels. The optimal cultivation pattern based on WEFG leads to 11% and 15.8% reductions in water and energy consumption, even with a 2.3% increase in cultivation area. The estimated profit for optimal pattern based on WEFG decreased by 13.67% due to lower cultivation levels of high‐yield crops such as onion and potatoes. However, the optimal cultivation pattern based on the WEFG index has decreased greenhouse gas emissions by 2%, leading to sustainable agricultural management. Therefore, the presented WEFG nexus index can be a practical metric for sustainable planning and management in the agriculture sector. [ABSTRACT FROM AUTHOR]

This paper aims to address father absence as a key contributory factor to child neglect and abuse and a cause of disrupted and unstable families by means of an explorative literature review. The study follows a biblical and multidisciplinary approach and collaboration between scholars from the fields of social work and theology in an effort to transform broken families. The Children's Act, 38 of 2005, stipulates that children in need of care and protection refer to children who face social issues such as abuse, absent parents, and children who abuse alcohol and drugs, among other things. These children require adequate care, love, and security. A stable family or home environment can provide stability, security, and a caring environment where children can develop to become emotionally healthy and pro-social. God can transform families, especially the families of children who receive the ministry of his Word. The Scripture in Jeremiah 31 verse 29 proclaims: "The fathers have eaten a sour grape and the children's teeth are set on edge". This quote refers to the involvement of the father as the primary leading figure in the family. It illustrates that proper fathering has a much broader significance than just the biological production of children. South Africa has experienced rapid changes, including shifts in family composition. There are many broken relationships, and father absence is a salient issue. Countless numbers of children in the South African landscape are being raised without their biological fathers. Many experiences no fatherly presence at all as they lack an alternative figure. Children are often humiliated for being fatherless and many families are challenged by father absence, and this creates in children a sense of loss and confusion. Hence, the aim of this article to reciprocate to father absence as social ill from a biblical point of view and to suggest a transformative ecclesial praxis. [ABSTRACT FROM AUTHOR]

Recent studies reporting widespread declines in arthropod biomass, abundance and species diversity raised wide concerns in research and conservation. However, repeated arthropod surveys over long periods are rare, even though they are key for assessing the causes of the decline and for developing measures to halt the losses. We repeatedly sampled arthropod fauna in a representative Swiss agricultural landscape over 32 years (1987, 1997, 2019). Sampling included eight study sites in four different semi-natural and agricultural habitat types and different trap types (pitfall, window, yellow bucket) over an annual period of 10 weeks to capture flying and ground dwelling arthropod taxa. In total, we analyzed 58,448 individuals from 1343 different species. Mean arthropod biomass, abundance and species richness per trap was significantly higher in 2019 than in the prior years. Also, species diversity of the study area was highest in 2019. Three main factors likely have contributed to the observed positive or at least stable development. First, the implementation of agri-environmental schemes has improved habitat quality since 1993, 6 years after the first sampling. Second, landscape composition remained stable, and pesticide and fertilizer was constant over the study period. Third, climate warming might have favored the immigration and increase of warm adapted species. Our results support the idea that changes in arthropod communities over time is highly context-dependent and complex. Implications for insect conservation: We conclude that the integration and long-term management of ecological compensation patches into a heterogenous agricultural landscape supports insect conservation and can contribute to stable or even increased arthropod abundance, biomass and diversity. Future studies are needed to clarify interdepending effects between agricultural management and climate change on insect communities. [ABSTRACT FROM AUTHOR]

Non-point sources of water pollution caused by agricultural crop production are a serious problem in Czechia, at present. This paper describes a new approach for the mutual delineation and assessment of different pollution sources where the critical points method is used to identify the origin of contamination and the source areas. The critical points, i.e., sites presenting the entry of quick surface and drainage runoff into waters, are classified into three (for surface pollution sources using a WaTEM/SEDEM model) or four (subsurface = drainage sources via the catchment-measures need index) categories, respectively. This enabled us to prioritize the most endangered areas at different scales, ranging from the third-order catchments to very small subcatchments, and to design the appropriate combination of control measures to mitigate surface and drainage water runoff, with these being the main drivers of associated pollution. This methodology was applied to a study conducted in the Czech Republic within the entire Vltava River basin, with a total area of 27,578 km
2 , and utilized in depth to assess a 543 km2 catchment of the Vlašimská Blanice River. When the effect of the designed surface runoff control measures system had been assessed for sediment transport through outlet profiles of the fourth-order catchments, the average reduction reached 43%. The total reduction in the subsurface transport of nitrogen within the fourth-order catchments was 24%. The approach and results are planned to be projected into river basin management plans for the Vltava River basin. Nevertheless, a thorough reassessment of current legislations and strategies is needed to enable the broader adoption of mitigation measures and sustainable management patterns within agricultural landscapes.
