Understanding long-term changes in topography and topsoil grain composition is crucial for the management of agricultural landscapes, especially in areas prone to wind erosion. This study investigates long-term changes in topography and topsoil grain composition within an agricultural landscape in south-western Slovakia. To analyse topographic changes over time, we used high-precision positioning measurements and airborne laser scanning to create digital terrain models (DTM) for the years 2011, 2017 and 2020. To assess changes in soil grain composition, we performed grain size analyses on soil samples collected during three different periods: M1 (1961-1970), M2 (2009-2015) and M3 (2015-2016). Changes in soil texture were evaluated to understand the impact of wind erosion on soil composition. The influence of windbreaks was also analysed by comparing the accumulation and deflation processes. The results showed significant changes in both topography and soil texture over the study period. The DTMs showed marked differences in the accumulation and deflation processes, highlighting areas affected by wind erosion. Comparisons of soil samples showed a shift in dominant soil types from loam and clay loam to silty loam, highlighting the effects of wind erosion. Analysis revealed a decrease in clay and silt content and an increase in sand content, indicating wind-induced soil degradation. The presence of windbreaks played a crucial role in reducing soil erosion by reducing wind speed, promoting soil accumulation and stabilising the landscape up to 80 m windward and 20 m leeward. The study highlights the complex interplay of climate and wind factors in shaping topography and soil properties and emphasises the protective role of windbreaks in agricultural landscapes over time. Our results show that wind erosion significantly alters soil texture, which can affect agricultural productivity. However, windbreaks have proven to be an effective measure in reducing soil erosion and maintaining soil quality. [ABSTRACT FROM AUTHOR]

The management of landscapes and agricultural activities significantly impacts phosphorus (P) and nitrogen (N) losses, directly influencing eutrophication risk. This study quantifies the eutrophication potential of different land covers through in-situ measurements and analysis of runoff and inorganic substances. The research was conducted in two sub-catchments in the Bedřichovský stream basin, Novohradské hory, Czech Republic: a forest-dominated upper sub-catchment (UFS) and an agricultural lower sub-catchment (LAS). Water flows and surface water samples were measured over a hydrological year (November 2017 to October 2018) to determine runoff and concentrations of nitrate (N-NO3−) and phosphate (P-PO43−). The ReCiPe 2016 method, as a tool for LCIA, was used to quantify the eutrophication potential, converting N and P concentrations into nitrogen equivalents (N eq ha−1 sub-catchment) for marine eutrophication and phosphorus equivalents (P eq ha−1 sub-catchment) for freshwater eutrophication. The potential loss of species (species·yr ha−1 sub-catchment) was assessed as follows. Results indicate UFS has about 60% lower freshwater and 80% lower marine eutrophication potential compared to LAS, along with about 60% lower potential for biodiversity loss. This highlights the role of forest and grassland covers in mitigating eutrophication and protecting water sources. These findings can guide landscape management practices to reduce eutrophication potential, enhancing environmental quality and biodiversity conservation. [ABSTRACT FROM AUTHOR]

In response to escalating water scarcity exacerbated by climate change and urbanization, this study introduces a sustainable solution for groundwater recharge in Pakistan's urban landscape. The implemented low-cost artificial recharge system, designed and established in June 2022, involves a 1.83 × 3.05 × 3.05 m (6 × 10 × 10 ft) pit filled with stones, coarse and fine crush, and sand layers, receiving rooftop runoff from a 39.63 × 10.99 m (130 × 36 ft) rooftop area of an office building. A borehole with perforated casing pipe of 15.24 cm (6 in) diameter and 15.24 m (50 ft) deep was installed in the pit for enhancing water recharge and filtration to the aquifer. Analyzing data from June 2022 to December 2023 reveals a positive correlation between rainfall and runoff, leading to a notable rise in the water table along with fulfilling the domestic water needs of more than 40 persons. The system demonstrates adaptability to urban settings, empowering communities themselves to manage water resources effectively. Its success highlights its potential for national scalability, offering a sustainable approach to groundwater replenishment amid growing water scarcity challenges. This groundwater recharge system may contribute to resilient water management in urban and agricultural landscapes, crucial for sustainable development and addressing emerging climate-change-induced water crises at the developing world, in general, and at the country level, in particular.

Cities serve as both political and economic hubs. Sustainable development has long been acknowledged as crucial to the well-being of the environment, people, and society. In order to improve the current state of spatial affairs and attain long-term resilience, humanity is looking for reliable and sustainable urban planning approaches. Urban agriculture has received a lot of attention in recent years as an enduring and pervasive kind of landscape. Although the contribution of urban agriculture has been well documented in many studies on economic, social and ecological aspects, there has been little discussion of its practical value as a tool for spatial development. Additionally, the potential of urban agriculture as a landscape approach remains underdeveloped. In summary, current research and practice lacks a scientific framework for considering urban agriculture as a landscape approach to intervene in urban spaces. To this end, this paper explores the potential of urban agriculture as a landscape approach in sustainable urban planning and design through qualitative case study. Taking Songzhuang in Beijing as an example, we discuss and summarise the operational value and potential of urban agriculture from a design perspective. The findings suggest that landscape-based urbanism that includes urban agriculture can harmonise social, economic, environmental and ecological elements. Finally, in order to provide a generalised approach, this paper proposes a scientific framework for articulating a landscape approach to urban agriculture to guide future research and practice.

Closed depressions are common landscape features across glaciated landscapes. Erosion and runoff from depression hillslopes may result in phosphorus (P) accumulation near the bottom of the depression, with this "legacy P" potentially at risk of loss to surface waters when drained via tile drainage. We assessed spatial patterns of soil P within a tile‐drained watershed in northeastern Indiana as a function of landscape position and agricultural management practices. Paired soil samples (depression bottom vs. hillslope contributing area) were collected from agricultural (n = 14) depressions at four depths (0–60 cm). Water‐extractable phosphorus (WEP), Mehlich‐3 extracted phosphorus (M3‐P), total phosphorus (TP), Hedley P fractions, and other physical and chemical characteristics were determined. To assess the risk of P loss, P desorption from surface soils (0–5 cm) was quantified using flow‐through experiments. Results showed that WEP, M3‐P, and TP were 2–10 times greater in the depression bottom compared to hillslopes across all depths. Long‐term management practices such as P application history and tillage influenced the magnitude of soil P concentration, degree of P saturation, and vertical stratification of soil P. Flow‐through experiments highlighted that the risk of P loss was highly dependent on M3‐P concentration for both hillslope and depression soils. Findings therefore indicate that closed depressions may act as hotspots for P cycling and loss in tile‐drained watersheds. Including low‐lying depressional areas as part of a routine soil sampling strategy combined with variable rate P application could lessen P accumulation in depressions and reduce P loading to surface waters. Core Ideas: Phosphorus accumulation in closed depressions of a tile‐drained watershed was assessed.WEP, Mehlich‐3 extracted phosphorus (M3‐P), and total P were significantly greater near the depression bottom compared to hillslopes.Topography and agricultural management influenced P accumulation within depressions.Phosphorus desorption during flow‐through experiments showed that P loss was dependent on M3‐P concentration.Soil sampling in depressions combined with variable rate P application could reduce the risk of P loss.

Honey bees are vital to human well-being and are under multiple stresses. We need to be able to assess the viability and productivity of honey bee colonies in different landscapes and under different management and climate-change scenarios. We have developed a prototype digital twin, HONEYBEE-pDT, based on the BEEHAVE model, which simulates foraging, population dynamics and Varroa mite infestation of a single honey bee colony. The main input data are land-cover maps and daily weather data. We have developed the pDT for simulating large areas and have tested it for the whole of Germany. We have also developed a web-based GUI that users can use to run the pDT for specific sites. Hive weight data from hundreds of hives will be used for calibration and validation.

Over the course of the postglacial period has managed to add degrade a substantial portion of the world's potential agricultural land. The soil loss and degradation that has repeatedly impacted regional societies around the world resulted from agricultural practices that increased the physical loss of soil (erosion), reduced soil organic matter, changed pH (acidification) or salinity, and disrupted or altered communities of soil life. In the coming century, as continued soil degradation threatens global food security while the global population keeps rising it is imperative that farmers develop and adopt soilhealth building (regenerative) practices to solve a problem that has plagued societies throughout history. Growing evidence suggests that agricultural systems that combine cover crops, reduced tillage, and diverse crop rotations can reduce erosion, enhance soil health and rebuild soil organic matter to cultivate beneficial soil life and harvest both economic and environmental benefits. In the coming post-oil world, global food security would benefit from a global effort to promote soil restoration to help addresses the challenge of sustainably feeding the world, increase soil-based carbon sequestration, protect on-farm biodiversity and reduce off-farm water pollution. Because soil security sets a solid foundation for global food security, agricultural policies and subsidies should be reformed to encourage farmers to adopt regenerative, soil-building practices.

In the contemporary agricultural landscape, agriculture faces four pressing demands: competitiveness, ensuring food security for a growing population, environmental sustainability, and providing farmers with acceptable living conditions. To meet this global challenge, digital technologies represent a major avenue for innovation and development towards modernized digital agriculture. In this context, irrigation advisory platforms have proven to be transformational tools for both farmers and policymakers, offering insights into the appropriate crop water requirements. This article presents a benchmarking analysis of around 20 professional irrigation advisory platforms. The methodology involves selecting 20 platforms based on accessibility ensuring geographical characteristic diversity. Our findings highlight key criteria shaping the ecosystem of such platforms, including the services offered and their objectives, the types of covered crops, the target users, the form, as well as the source, the availability of the platform, and the variety of data utilized. Lastly, we discuss the main conclusions drawn from our analysis and provide insights into the challenges and future perspectives of irrigation advisory platforms in enhancing agricultural practices and sustainability.

Amidst the agricultural landscape of Ghana lies a complex interplay of practices governing the use of approved pesticides and adherence to safety standards among farmers. By analysing data gleaned from 400 farmers through the multistage sampling technique, our aim is reveal the multifaceted influences that shape farmers' decisions in the use of approved pesticides and safety compliance. Age, education, marital status, farm ownership, experience, farm size, access to equipment and services, cooperative membership, secondary occupations, and income, significantly influence farmers' choices in the use of approved pesticides. Furthermore, compliance with safety protocols is found to be influenced by factors such as farm size, access to extension services, and the perceived relative advantage of pesticides. We advocate for policies that promote the use of approved pesticides and prioritise safety standards in agricultural practices. This may include strengthening regulatory frameworks, incentivising sustainable farming practices, and enforcing penalties for noncompliance with safety regulations. [ABSTRACT FROM AUTHOR]

Context and background This study aims to study, through a socio-systemic approach, the cohabitation between agricultural land and gold panning, if not the occupation of agricultural land by gold panning. To this end, we decided to focus on the case of the rural commune of Bancoumana, Kati circle, Koulikoro region, an agricultural area par excellence, but faced with the invasion of gold panning. This commune, located on the outskirts of Bamako, is experiencing a desire for its land suitable for agriculture (cereals, citrus fruits, fruits and vegetables). Through this study, we ask the question of how agriculture coexists with gold panning? What are the effects and impacts of one on the other? What measures or arrangements have been taken by the politicaladministrative authorities to protect agricultural land from gold panning? How are these measures perceived by the populations, particularly farmers? Goal and Objectives: Study the cohabitation between agricultural land and gold panning. This involves studying the effects, if not the impacts, of one on the other. Methodology: To carry out the study, our approach is based on empirical research methods. First, we carry out a documentary analysis in order to pose the problem of the study. Secondly, we carry out field surveys using individual and collective interview guides with the stakeholders concerned, in particular farmers, gold miners, local and regional authorities, and managers of farmers' defense NGOs. For the analysis of the data collected in the field, we favored the analysis of thematic content according to our centers of interest. The data collected in the local "Bambara" language were transcribed into French for this purpose. Results: The results of the study reveal that the idleness of rural and urban young people explains their rush to gold panning areas. It also shows that gold panning seriously impacts agriculture, particularly family farming. The impacts are of several orders. Encroachment or invasion on agricultural areas, flight of agricultural labor, decline in agricultural productivity, decline in agricultural income and land conflicts between farmers and gold miners.

Honey bees exhibit age polyethism and thus have a predictable sequence of behaviors they express through developmental time. Numerous laboratory studies show exposure to pesticides may impair critical honey bee behaviors (brood care, foraging, egg-laying, etc.) that adversely affect colony productivity and survival. There are fewer studies that examine the impacts of pesticides in natural field settings, especially given the challenges of implementing treatment groups and controlling variables. This study helps address the need for impact studies on pollinators under field conditions to assess the consequences of chemical overuse and dependency in agricultural and urban landscapes. To assess the impact of systemic pesticides in a natural field setting on worker bee behavioral development, observation hives were established to monitor changes in behaviors of similarly aged workers and sister queens within 2 experimental groups: (i) colonies located near point-source systemic pesticide pollution (pesticide contaminated treatment), and (ii) colonies embedded within a typical Midwestern US agricultural environment (control). In this study, worker bees in the contaminated environment exhibited important and biologically significant behavioral differences and accelerated onset of hive tasks (i.e. precocious behavioral development) compared to similarly aged bees at the control site. Queen locomotion was largely unaffected; however, the egg-laying rate was reduced in queens at the contaminated (treated) site. These results show that environmental pesticide exposure can disrupt colony function and adversely affect worker bee behavioral maturation, leading to reduced worker longevity and decreased colony efficiency.

In pursuing advancing solar energy systems, this research uniquely occupies a position at the intersection of photovoltaic (PV) efficiency, innovative design and aesthetic integration into urban landscapes. This study explores the potential of thin solar cells applied to spherical and hemispherical surfaces and the influence of temperature variations throughout the day. By conducting a comprehensive analysis of voltage–current diagrams, the study deciphers the intricate interconnections of spherical geometries and their response to external thermal impacts, elucidating their subsequent effects on energy conversion efficiency. Moreover, it delved into the dynamics of connecting multiple spherical modules, unveiling their potential to form artistic and utilitarian constructs such as solar trees and architectural embellishments. The findings indicate that while spherical configurations provide superior aesthetics and a power generation profile comparable to solar tracking systems, hemispherical configurations offer a 32% increase in efficiency compared with the spherical configuration and a notable reduction in land footprint. This research underscores the importance of striking a balance between aesthetic appeal, efficiency and land utilization, providing valuable insights for the future of PV technology integration into urban and agricultural landscapes.

Wasteland governmentality has long shaped colonial and postcolonial landscape governance across the planet. While historically wasteland classification was deployed for agrarian land settlement and silviculture, with extended urbanisation it is increasingly used to consolidate landscapes of extended urban nature. These landscapes are in turn subjected to state-led land enclosures for urban and infrastructure development and for greenwashing. This paper investigates the political construction of one such landscape of extended urban nature, the Aravalli region, a geological feature which runs parallel to the extended corridor urbanisation in the Delhi National Capital Region (NCR). Particularly, I examine how in the name of regulating mining, urban development, and pollution in the Delhi NCR, the revenue wastes including sacred groves, hills, and other village commons falling in the Aravallis have been consolidated as a state space. I examine how the patchwork of communities assembled in the extended urban fabric of the region deploys the sacred to counter land enclosure and the emptying out of meaning. I discuss three such modalities of the sacred in the region, namely, its use by agrarian villages to assert land rights over sacred forests, the misuse of the sacred by temple committees to produce faux nature, and its use by emergent urban environmental movements in the region to frame an anti-wasteland politics. Focusing my attention on the state, I discuss the need for a nuanced understanding of emergent urban environmentalism in the region as restorative commoning beyond the binary framings of bourgeois versus the poor.

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 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.

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.

Integrated landscape management is a timely answer to China's missions of achieving ' harmony between humanity and nature ' and ' synergistic high-quality development of social-economic-natural complex ecosystems.' It is also a theoretical and practical framework for achieving the goals of ecological restoration, farmer livelihood improvement, and the synergistic improvement of the quality of the natural landscape and the well-being of residents. Following the concept of ecological and livelihood inclusive development and based on the theoretical and practical achievements of integrated landscape management overseas, this study provides a new perspective for the modernization of China's ecological governance system and governance capacity through the analysis of semantic structure, value logic, the theoretical paradigm, the action framework, and the practice of integrated landscape management. The main findings include: First, integrated landscape management is a strategic framework for synergistically achieving the multiple goals of agricultural production, ecosystem conservation, sustainable natural resource management, and human health and well-being. Second, integrated landscape management is a direct manifestation of the concept that ' lucid waters and lush mountains are invaluable assets,' a concrete practice of ' production space-living space-ecological space' coordination, the best way to enhance ' ecological security-production security-livelihood security,' and a governance system that achieves ' top-down' and 'bottom-up' integration and adaptation. Third, integrated landscape management is a composite logic of ecological governance with multi-objective synergy, multi-objective dialogue, multi-scale interaction, multi-action connectivity, and multi-link adaptation. Fourth, integrated landscape management is an ecological governance system action consisting of identifying the list of problems and related subjects, clarifying action goals and governance measures, designing management programs and support mechanisms, and implementing integrated actions and assessments. Based on the above conclusions, this study embeds the theoretical paradigm and action framework of integrated landscape management in the context of the operational practice of the Grain to Green Program in China, reflects scientifically on the possible improvement directions of the Grain to Green Program, and provides practical examples for integrated landscape management.

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 NO3, 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.

The escalating carbon dioxide emissions leading to global climate change are acknowledged as a paramount environmental challenge in the twenty-first century. The significance of land use systems in stabilising carbon dioxide levels and enhancing carbon sink potential has gained noteworthy attention from both the scientific and political communities. The Intergovernmental Panel on Climate Change emphas ises that agroforestry systems present vital prospects for synergising climate change adaptation and mitigation efforts, offering substantial technical mitigation potential. Windbreaks are well-known agroforestry systems in Hungary and form an important part of agricultural landscapes. The improved agroforestry subsidy system in our country makes it relevant to model the carbon sequestration potential of windbreaks. In the framework of the ForestLab project we plan to develop a carbon sequestration model specific for Hungarian agroforestry systems. In this study, as a preparatory step of the model development, we assessed the yield class distribution of Hungarian windbreaks by tree species group and identified variables that had significant effect on yield class based on the data of the National Forestry Database. Our results show that among the examined effects the most important predictor of the yield class of windbreaks was the tree species group, followed by the thickness of the productive soil layer and the hydrology of the site.

We investigated the impact of the effluent from four constructed wetlands on the structure of the macroinvertebrate and macrophyte communities in the receiving watercourses including the river Pesnica and the Sejanci Stream and Pavlovci Stream in NE Slovenia. Macroinvertebrates and macrophytes were sampled on the sites upstream and downstream of the inflows. Selected environmental parameters were also analyzed on each site. Among the measured chemical and physical parameters, the concentration of NH 4 –N in the water was the only one that was changed significantly by the inflow from constructed wetlands (CWs). The metrics obtained on the base of the macroinvertebrate community, including the values of diversity indices, the proportion of sensitive taxa and the saprobic index, revealed no significant statistical differences between the upstream and downstream values. Inflows of effluent also have no detectable impact on macrophytes. The removal of degradable organic matter, nitrogen, phosphorus, and suspended solids from the wastewater in studied CWs was sufficient to support this situation, and this has been encouraging to construct new CWs. • The concentration of NH 4 -N was significantly higher downstream the CWs. • Inflows had no detectable influence on macrophyte and macroinvertebrate communities. • Wider usage of similar CWs is recommended.

• Pan-European agricultural typology of farming-driven freshwater impacts. • Mapping of Pesticide, Nitrogen, hydromorphology and water abstraction pressures. • Agricultural freshwater pressure hotspots in the Mediterranean and Western Europe. • Incorporating agricultural intensity increases correlation with the ecological status. Agriculture impacts the ecological status of freshwaters through multiple pressures such as diffuse pollution, water abstraction, and hydromorphological alteration, strongly impairing riverine biodiversity. The agricultural effects, however, likely differ between agricultural types and practices. In Europe, agricultural types show distinct spatial patterns related to intensity, biophysical conditions, and socioeconomic history, which have been operationalised by various landscape typologies. Our study aimed at analysing whether incorporating agricultural intensity enhances the correlation between agricultural land use and the ecological status. For this, we aggregated the continent's agricultural activities into 20 Areas of Farming-induced Freshwater Pressures (AFFP), specifying individual pressure profiles regarding nutrient enrichment, pesticides, water abstraction, and agricultural land use in the riparian zone to establish an agricultural intensity index and related this intensity index to the river ecological status. Using the agricultural intensity index, nearly doubled the correlative strength between agriculture and the ecological status of rivers as compared to the share of agriculture in the sub-catchment (based on the analysis of more than 50,000 sub-catchment units). Strongest agricultural pressures were found for high intensity cropland in the Mediterranean and Temperate regions, while extensive grassland, fallow farmland and livestock farming in the Northern and Highland regions, as well as low intensity mosaic farming, featured lowest pressures. The results provide advice for pan-European management of freshwater ecosystems and highlight the urgent need for more sustainable agriculture. Consequently, they can also be used as a basis for European Union-wide and global policies to halt biodiversity decline, such as the post-2027 renewal of the Common Agricultural Policy.

Water quality standards are instrumental in evaluating the status of water bodies, and in providing protective and restorative endpoints. To date, much of the infrastructure used to implement water quality standards has been directed towards remediating and managing pollution from point source discharges. However, pollution from diffuse sources is the leading cause of water quality impairment, especially by nutrients. Although the effects of nutrient enrichment on streams is well studied, and ecological thresholds identified, those thresholds have not been widely adopted as standards primarily because they are not attainable by point sources. Clearly, a framework for adopting and applying standards to manage pollution from diffuse sources needs to be decoupled from those intended for point sources. This paper argues for a relatively unstructured distributional approach to predict how ecological responses might shift in response to management of diffuse sources. The approach calls for first developing a deterministic model of stressor and response variables, followed by a reformulation as a Bayesian model. In the case here, a structural equation model was developed that linked nutrient enrichment, habitat quality, and chloride and manganese concentrations to an index of macroinvertebrate quality. Results from the Bayesian representation suggest that in landscapes where the drainage network has been highly modified for agricultural production, reduction in total phosphorus alone is expected to have a modest (but non-trivial) effect on macroinvertebrate condition, shifting the distribution of scores up by 1 point. The addition of habitat restoration is likely to shift the distribution upwards by 4 points, an effect size observed in Ohio, USA from other large-scale restoration efforts. [Display omitted] • Pollution from diffuse sources is now the leading cause of water quality impairment across the USA. • Water quality targets intended to manage diffuse pollution are likely to be more stringent than what is feasible for wastewater treatment plants. • This paper describes how Bayesian models can be used to assess water quality targets used in managing pollution from diffuse sources.

Agricultural landscape transformation has profound impacts on regional sustainable development. Understanding the relationship between agricultural landscape transformation and socio-ecological system is fundamental to both social prosperity and ecological environment. Rice-crayfish field (RCF) as a unique agricultural model is widely practiced in traditional farming areas and causes significant landscape transformation. However, the RCF remains less understood and its impacts on socio-ecological systems need to be comprehensively investigated. China has a developed crayfish industry with over 90% of the world's crayfish production, which provides an interesting lens to examine the RCF-led agricultural landscape transformation. This research proposes a novel research framework to analyse the spatial dynamic of RCF and its complex impact on socio-ecological system. Using remote sensing and geospatial data analysis, this study explores the spatiotemporal heterogeneity of RCF-led landscape transformation and socio-ecological system. In addition, the impacts of RCF on socio-ecological system are examined by the Pearson correlation analysis, root mean square error and regression model. The results reveal that RCF has dramatically expanded and transformed from paddy fields. The socio-ecological system presents obvious spatial agglomeration characteristics. RCF has the potential to increase farmers' income and alleviate rural poverty, but it is not conducive to grain production and water consumption. The RCF-led agricultural landscape transformation could be a double-edged sword to socio-ecological system. To balance social and ecological systems, it is necessary to manage and design the rational development of RCF to support sustainable agricultural landscape transformation. [Display omitted] • Spatial dynamic of rice-crayfish field (RCF) is measured by remote sensing data. • The socio-ecological system consists of water, food and economic subsystems. • RCF could be a double-edged sword to socio-ecological system. • RCF promotes economic benefits but threatens grain production and water yields. • This research provides references for sustainable agricultural transformation.

[Display omitted] • Flow and sediment connectivity was mapped in the agricultural terraced catchment. • Incorporation of natural-artificial linear landscapes alters spatial patterns of connectivity. • Connectivity gradually increased with the closing of the distance to the linear landscapes. • Artificial ditches enhance both lateral and longitudinal connectivity than road networks. • Introduced weight factor to calculate the index generated more reliable connectivity map. Linear landscape elements, such as man-made ditches and road networks, play a pivotal role in the transport of water and eroded sediments. Yet very few studies have focused on the variations in drainage flow paths disturbed by artificial linear landscapes and their contribution to flow and sediment connectivity (FSC). This study utilized the index of connectivity (IC) to examine and distinguish the impact of natural and artificial linear landscape elements (i.e., natural streams, man-made ditches, and road networks) on the spatial distribution of FSC. The method was employed in a typical agricultural terraced catchment of the Honghe Hani Rice Terraces World Heritage Site of China, based on two weight factors - roughness index (RI) and Rndvic factor. The results indicate that the incorporation of the linear landscape elements for the IC calculation remarkably affected the spatial distribution of FSC. Specifically, FSC values notably increased by closing the distance to linear landscape elements within a specific threshold. Moreover, in the confluence between natural and artificial linear landscape elements, the mean value of FSC was higher compared to scenarios without any or only one linear landscape element. In comparison, the presence of road networks only improved lateral connectivity by modifying the surface flow along east-west directions, while man-made ditches significantly influenced both longitudinal and lateral connectivity to a larger degree, especially in the terraced area. This finding underscores the effectiveness of ditch constructions as management practices for the regulation of water resources and facilitating the downstream transfer of sediment. Field observations and validation confirmed that Rndvic, which incorporates vegetation variable as a weight factor in the calculation of IC, yields more accurate and reliable maps of FSC than that of RI. This study holds far-reaching significance for water resources management and landscape sustainability within terrace-protected areas, providing invaluable insights for decision-makers.

Agriculture provides food, fibre and other resources for people throughout the world, but clearing of native vegetation for agriculture has led to profound losses of biodiversity and changes to ecosystem function. There is growing recognition of the need to retain and restore (semi)natural vegetation in farmland for biodiversity conservation. However, managing such vegetation is complicated by trade-offs between different objectives, and knowledge to guide management is dispersed across multiple fields. We integrate knowledge on the benefits and disbenefits of (semi)natural vegetation on farms for achieving six objectives, including biodiversity, farm production, carbon stocks, soil health, local water cycle, and amenity/human wellbeing. Drawing on scientific literature from temperate southern Australia as a case study region, we develop a conceptual model of the relationships between these objectives and seven common types of native and restored vegetation on farms. From 224 peer-reviewed empirical studies, we identified 19 'causal pathways' by which (semi)natural vegetation provides benefits or disbenefits for the identified objectives. More pathways result in benefits than disbenefits , and generally there is greater support for the benefits provided by native than restored vegetation. Nonetheless, farm-level restoration (revegetation) contributes towards reversing the negative consequences of vegetation loss but this process takes time. Various 'moderating factors' serve to alter the outcome of most pathways. For example, restoration age affects the benefits that revegetation provides for biodiversity, carbon stores, soil health and water cycling. Many moderating factors are related to management practices (e.g. stock grazing, use of fertilisers), highlighting opportunities to enhance the benefits of (semi)natural vegetation in farmland. Relatively little is known about the value of (semi)natural vegetation for amenity/human wellbeing, or the outcomes resulting from natural regeneration. The conceptual model and causal pathways identified here contribute towards a more comprehensive understanding of the diverse benefits of (semi)natural vegetation on farms, which is essential for effective management and the sustainability of agricultural landscapes worldwide.
