Improved water management can increase food self-sufficiency in urban foodsheds of Sub-Saharan Africa

Rising urban food demand in Sub-Saharan Africa will put pressure on local resource boundaries, such as the available land area and water resources. In assessing the extent to which urban centres can source from nearby areas in future, earlier analysis has concentrated on agronomic measures, aiming at yield gap closure. Here, we address the potential of local water conservation measures to help achieve food self-sufficiency in Sub-Saharan Africa by 2061–2070, along the concept of urban ‘foodsheds’, matching crop-based food supply and demand in the surroundings of large cities for all major food groups. We find that ambitious but plausible levels of water conservation, primarily raising productivity on rainfed lands, have the potential to increase overall food production by 12% and food self-sufficiency levels in all major foodsheds to over 75%, with the region as a whole becoming self-sufficient. The increase in production could limit the projected required expansion of agricultural land use by more than 25%, which has important implications for biodiversity, land use-related conflicts and carbon sequestration.

Seasonal movements of small-island birds along habitat and elevation gradients highlights the conservation value of small-scale agroforests

Knowledge on species distributions and seasonal movement patterns within landscapes is important for understanding their ecology and roles in agroecosystems, and is critical for enabling their effective conservation and monitoring, particularly in small-island states where conservation resources are limited. We undertook bird surveys to examine species distributions across a range of agricultural land-use intensities and elevations on the Caribbean island of Grenada by collecting data over 6 repeated monthly surveys (3 wet season, 3 dry season) at sites located in a variety of habitats spread over 6–300 m elevation. We observed a gradual upslope increase in bird species diversity and abundance from the mid-wet season to the late-dry season, as well as a movement from reduced-canopy habitats to closed-canopy habitats in the dry season. The mid-elevation hillsides of Grenada consist of a diverse mosaic of closed canopy secondary forest patches, interspersed among more open agroforests and small-scale cropping and grazed areas. These agroecosystems appear to provide important habitats to birds throughout the year, especially open canopy agroforests in the wet season. We also found that open mixed agroforests contained a greater diversity of fruit, flower, and seed resources than closed canopy habitats such as secondary forest, cacao agroforests, young secondary forests, or dry forest scrub; and that plant food diversity was highest in the wet season. However, bird abundance significantly increased in closed canopy forest habitats during the dry season, suggesting that intact canopy forests provide important dry season habitat for many Grenadian birds, which may be particularly important for species in drier lowland areas experiencing more intensive agricultural land use and urban and resort development. Overall, this research demonstrates the importance of maintaining the functional connectivity of treed habitats at local and landscape scales for species conservation, as well as the contribution of diverse, small-scale agriculture to maintaining small-island bird communities.

Sustainable (balanced) land use development is the basic foundation for the formation of Ukraine’s land system

The article examines the key aspects of sustainable land use as a foundation for the effective development of rural areas and communities. Balanced land use should be viewed through the lens of land management development and the implementation of integrated land resource management. The excessive intensification of agriculture and the rapid expansion of cities lead to the loss of beneficial land functions, causing land degradation. The study assessed the ecological stability of territories and revealed an unsatisfactory state of ecological stability in Ukraine, associated with the high level of land plowing (68.4%). It is noted that preserving and restoring land as a unique natural resource requires active intervention by government bodies to stimulate measures for the protection and restoration of land resources through the implementation of effective environmental initiatives. Due to progressing erosion, approximately 40–50 billion hryvnias are lost annually. It is proposed to develop a conceptual strategy for enhancing the ecological sustainability of land management at the legislative level, as well as during the reform of land relations, with a focus on the ecological reorganization of the land management system in the country, regions, and newly established territorial communities. Ecologically sustainable land use is possible only with the implementation of scientific and technological advancements and the orientation of the economy towards ecological principles at the national, regional, and local levels. Sustainable land use development means not only the effective utilization of land resources but also the creation of an appropriate land institutional structure and a favorable environment for land resource management, as well as the formation of social relations that promote the rational use of ecosystems while maintaining a balance between environmental, economic, and social components. In recent years, the practice of farming under market conditions has confirmed that the productivity and efficiency of agricultural activities primarily depend on the effective use of agricultural land. Modern research presents various approaches to identifying factors that influence the efficiency of agricultural land use. It should be noted that effective land use in agricultural enterprises must be combined with economic efficiency in land management. One of the important ways to achieve this is by enhancing the operation of agricultural producers, as well as improving the mechanism based on the integration of ecological and economic components, which ensure the quality use of agricultural land.

Assessing the Alteration of Soil Quality under Long-Term Fertilization Management in Farmland Soil: Integrating a Minimum Data Set and Developing New Biological Indicators

The key role of soil quality improvement in achieving sustainable agricultural development based on highly intensive use of farmland is increasingly being recognized, as is the ponderance of suitable evaluation of the soil quality. The overarching goal of this study was to determine an accurate assessment framework by the comparison of the scoring function (linear and non-linear) and integration method (area and weighted additive), which integrally evaluates the soil quality of an eleven-year field fertilization experiment (including CK, no fertilizer; CF, conventional fertilization; SF, formulated fertilization; SFO, SF with organic fertilizer). Thirty-three properties, including eighteen physiochemical-related and fifteen biological-related properties, associated with soil functions were measured as potential soil quality indicators, and the soil multifunctionality (SMF) was applied to validate the soil quality indices (SQIs). Principal component analysis and relationship analysis were used with indicators sensitive to management to determine a minimum data set (MDS). The results showed that the electrical conductivity, large macroaggregate-associated total nitrogen, small macroaggregate-associated organic carbon, carbon fixation, and enzyme activities of phenol oxidase and cellulase were chosen as the MDS. All the SQIs were significantly correlated with the SMF (p < 0.05). The fertilization strategies affected most indicators in different ways, and the index developed using the non-linear function and weighted additive integration method (SQI-NL) had the best sensibility and discriminability. The SQI value with the SQI-NL-MDS method was higher following the fertilization treatments than that of no fertilizer (p < 0.05), and the treatment of the organic fertilizer had the highest SQI value (0.66). Soil quality evaluation in long-term fertilized farmland suggested that the soil quality constraints between treatments of synthetic and organic fertilizer are related to the soil functions of nutrient cycling and sustain biological activity due to their higher contribution rates to the SQI in the organic fertilizer treatment, which provides insights into ways to reduce the gap in soil quality. The framework method can provide an accurate quantitative tool for the evaluation of soil quality from the target indicators by bridging management objectives and field-level actions.

Earthworm influence on soil aggregate distribution and protected carbon at managed forest sites in Vermont, USA

The long-term effect of non-native earthworm species on forest soil carbon storage is not clear. While initial invasion into earthworm-free soils stimulates carbon losses, there is evidence that carbon stabilization in soil aggregates is enhanced. Fourteen managed forest sites throughout Vermont were sampled to identify and enumerate earthworms, and determine soil aggregate distribution and physically protected carbon. Most of these sites were northern hardwoods reforested in the mid-20th century after agricultural land use. Soil at six 50 × 50 cm subplots at each site was sampled to a depth of 20 cm below the Oe horizon and the mineral soil fractionated into free microaggregates (<250 μm), small macroaggregates (250–2000 μm), and large macroaggregates (>2000 μm). Microaggregates were then isolated from the macroaggregates and organic carbon determined. Mean earthworm numbers below the Oe horizon at each site ranged from 0 to 313 individuals m−2 and ten different species were identified, representing all earthworm ecotypes. Four sites had no earthworms in the soil layer sampled, three sites had earthworms in every subplot with up to six different species, and seven sites had subplots both with and without earthworms. When subplots were grouped by number of species present, there was a trend towards a greater fraction of the mineral soil in macroaggregates containing greater protected carbon, and a lower fraction of free microaggregates. A paired t-test of subplots from the seven sites with variable earthworm presence showed significant differences in the same trends and there was significantly greater mineral soil total carbon and protected carbon in the subplots with earthworms. These results are consistent with recent research into earthworm effects on soil carbon stabilization. While initial invasion likely resulted in a negative carbon balance, our findings suggest that earthworms can enhance transfer of carbon into physically protected pools in these forest soils.

Restructuring agricultural land use in Ukraine. Directions for development

The intensity of agricultural land use in Ukraine was analyzed based on soil quality and the values of the land-use intensity (LUI) index and the land-use capacity (LUC) index. In the administrative districts of Cherkasy region, the LUI index ranged from 0.07 to 1.0, and the LUC index ranged from 0.01 ha per 1000 UAH of gross output to 0.19 ha per 1000 UAH, which points to considerable difference in land-use intensity and agricultural land-use capacity. New approaches should be sought to improve the management and use of agricultural land. Functional land use areas should be restructured, in particular, by implementing non-traditional methods of agricultural land use. The results of the study indicate that land-use functions should be modified over an area of 5,343,900 ha, where 2,049,900 ha should be converted to crop rotations for soil protection, 208,000 ha – to protective forest margins; and 2,878,000 ha – to non-traditional forms of agricultural land use. Motives: The purpose of the article was to propose a methodological approach for assessing the intensity of agricultural land use and to suggest directions for land-use restructuring to improve its ecological status. Aim: In the proposed methodical approach, the intensity of agricultural land use was assessed with the land-use intensity (LUI) index and the land-use capacity (LUC) index. To reduce plowing and increase land-use intensity, the functions of degraded arable land should be modified over an area of 5,343,900 ha, where 2,049,900 ha should be converted to crop rotations for soil protection, 208,000 ha – to protective forest margins; and 2,878,000 ha – to non-traditional forms of agricultural land use. Results: The article substantiates the need to modify the functions of arable land over an area of 5,343,900 ha, where 2,049,900 ha should be converted to crop rotations for soil protection, 208,000 ha – to protective forest margins; and 2,878,000 ha – to non-traditional forms of agricultural land use.

Impact of Land Use Changes on Soil Erodibility in the Outer Himalayas

Land use change hurts soil characteristics such as permeability, soil texture and aggregate stability, soil erodibility etc. which make soils susceptible to erosion and degradation. The outer Himalayan region is prone to large-scale soil erosion by water owing to the vast disparity in the slope gradient, undulating relief, largely mountainous joined with high-intensity rainfall and lithological characteristics of these rocks. Soil erodibility, one of the key factors affecting the rate of erosion can be estimated by using various soil erodibility indices. In examining erodibility indices across various land use changes, it was evident that both the clay ratio (CR) and modified clay ratio (MCR) escalated as land use shifts from forest to more disturbed environments. As we transit from forest to agriculture, these ratios increased and were even more marked in the transition from forest to wasteland. The erosional behaviour as per CR and MCR in agriculture land use transitions could be arranged in the order that forest &lt; agriculture &lt;builtup&lt; wastelands. Among wasteland use transitions, the high CR and MCR indicated potential challenges in soil management, while the lower CR and MCR in transitions to agriculture and forest suggested more favourable soil conditions for these specific uses. The CR and MCR ratios indicated that the lower the ratio, the more would be the clay accumulation and lesser the erosion. This information is crucial for understanding the implications of land use changes on soil erosion and health and for guiding effective land management practices in diverse ecological settings.

Assessment of land use change in the dryland agricultural region of Córdoba, Argentina, between 2000 and 2020 based on NDVI data

The dryland region of Córdoba province experienced a strong increase in agricultural land-use in the 21st century. Between years 2000 and 2020 the temporal variation of land-use measures derived from the seasonal variation curve of the Normalized Difference Vegetation Index (NDVI) was analyzed. In eleven departments of the region, the following NDVI measurements wereobtained for each crop cycle from September to April: minimum value (NDVIn), maximum value (NDVIx), amplitude (NDVIa=NDVIx-NDVIn) and mean value (NDVIm). The sowing percentage per department was analyzed spatially and temporally, as well as the land use indicators. Both NDVIn and NDVIx are related to the sowing area per department, determining a negative correlation (-0.36) for NDVIn and a positive one (0.596) for NDVIx. The positive correlation with NDVIa (0.569) is considered directly linked to the agricultural land use. The seasonal variation of the NDVI showed changes over time, which werecompatible with the increase in agricultural activity in the region. Although the increase in agricultural land use was noticeable through both the decrease in NDVIn and the increase in NDVIx, along with a general trend towards rising NDVIa values, the variation was more apparent in those departments where agricultural activity increased to a greater proportion.

The development of fishery-photovoltaic complementary industry and the studies on its environmental, ecological and economic effects in China: A review

The fishery-photovoltaic complementary industry is an emerging industrial model in China that integrates aquaculture with the solar industry. This innovative model involves conducting aquaculture activities while installing photovoltaic modules on the water surface to harness solar energy for electricity generation. However, despite its rapid growth in China, this model lacks substantial scientific data support across various domains. Therefore, based on an analysis of relevant research literature, this study reviews the current development status, environmental and economic effects, as well as challenges faced by the fishery-photovoltaic complementary industry in China. The aim is to provide scientific references for promoting sustainable development within this sector. The findings reveal that existing fishery-photovoltaic complementary industry projects are primarily concentrated in the middle and lower reaches of the Yangtze River and Pearl River Basin. The geographical distribution of these projects is predominantly influenced by local aquaculture areas and available solar energy resources, with a greater impact observed from the former rather than the latter. During summer months when water is shaded by photovoltaic panels, a slight decrease in the average water quality parameters across cases was observed, such as a decrease of 0.2 units in pH, a decrease of 1.06 °C in water temperature, a decrease in dissolved oxygen levels of 0.8 mg/L, inorganic nitrogen content and total phosphorus concentration dropped by 0.08 mg/L and 0.02 mg/L respectively. Conversely, there is a moderate increase noted in total nitrogen and ammonia nitrogen levels. The conclusion of the effect on phytoplankton biomass is not uniform, but it will certainly reduce zooplankton biomass. The impact on the species diversity of the zooplankton community was minimal, and its direction, whether positive or negative, varied depending on the specific aquatic ecosystem. A certain degree of shade is advantageous for the cultivation of shade-loving fish. Through the strategic deployment of photovoltaic panels and the implementation of scientific stocking practices, it is possible to achieve sustained levels of fisheries production. This model also can reduce an average of 978.6 tons of CO2 emissions per megawatt per year through energy production, thus achieving the combined goals of energy conservation and emissions reduction, and ensuring the profitability of power generation. Additionally, compared with the land utilization area of 3.66 hm2 per megawatt of traditional ground-mounted photovoltaics, fishery-photovoltaic complementary only requires 1.64 hm2, which can significantly save land resources by utilizing water surfaces, which mitigates the conflict between land use for agriculture and renewable energy installations. At the same time, research also pointed out that the existence of fishery-photovoltaic complementary will inevitably have some negative impacts on bird communities. Economic analyses indicate that while initial infrastructure costs and long payback periods pose challenges, the overall economic feasibility is promising, especially with governmental support and technological advancements. However, several challenges need to be addressed for further development: these include difficulties associated with infrastructure construction and initial costs, long payback periods; insufficient experience and technical support; as well as a lack of research on ecological and environmental impacts - particularly an urgent need for comprehensive life cycle assessments encompassing both environmental and economic aspects. Future research should focus on life cycle assessments, improved PV technology integration, and optimized aquaculture practices.

ANALISIS DAYA DUKUNG LAHAN PERTANIAN SEBAGAI UPAYA MENDUKUNG KETERSEDIAAN PANGAN DI KAWASAN SLEMAN TENGAH

The Central Sleman area is a peri-urban area directly adjacent to Yogyakarta, making land conversion increasingly prevalent and unavoidable. In comparison, the Central Sleman area has a role as one of the food barns due to fertile land conditions and is suitable for agriculture. Intensive conversion of agricultural land to non-agricultural land will result in the loss of productive agricultural land, resulting in decreased rice production. This will result in high rice imports and reduced employment in the agricultural sector. This research aims to analyze the development of agricultural land use, its projection, and the carrying capacity of agricultural land in the Central Sleman Region. The calculation of the agricultural land carrying capacity is based on Odum, Howard, and Issard. The results showed that the Central Sleman Area has a decreasing rate of change in the agricultural land area every year in Kapanewon. The calculation results of agricultural land's carrying capacity show that in 2020, land's carrying capacity exceeded 0.83. The results of the projection calculation in 2024 found that 4 out of 5 Kapanewon in the Central Sleman Region cannot achieve food self-sufficiency. Therefore, efforts are needed to increase the carrying capacity of agricultural land, mainly through increasing the productivity of food crops and protecting agricultural land from land conversion.

The Driving Forces that Influence Land Use Land Cover Changes in Khwisero Sub County, Kakamega County, Kenya

Land use land cover changes have to a great extent changed the world's landscapes, rebuilding environments and what they provide to humans during the time spent supporting the rising population across the globe. The drivers of these changes vary from location to location causing varying effects that challenge the essential design and the functioning capacity of the land quality with flowing consequences to land quality. A cross sectional descriptive design together with a longitudinal design were used. A random sampling was used to obtain a sample size of 384 from a study population of 113,476. Based on agriculture, forest land, bare land and built up land categories, the study classified Landsat images through supervised classification algorithm then applied post - classification comparison change detection to measure land use land cover percentage area change over time. Primary data was collected through interviews and discussions with key informants, field observations, and questionnaires administered to individual households in Khwisero Sub County. Secondary data involved downloading Landsat images (Landsat 7, 8 and 9; 30-meter multispectral), summaries and citation of other works carried in journals articles, original documents, annual reports, development plans and internet. Quantitative data analysis involved measures of central tendency and measures of dispersion (SPSS) and analysis of variance (ANOVA). Qualitative data was analysed by organizing and grouping the arising issues into various categories relevant to the study. Land use land cover classification of the study area realized four land use land cover classes of agriculture 81.34 km2, forest 52.75 km2, built up 8.86 km2 and bare land 2.65 km2 for the study area as at 2023. Change detection noted that agricultural land use has been reducing from 2002 to 2023, built up has been increasing from 2002 to 2023, bare land increased between 2002 to 2012 but decreased between 2012 and 2023 while forests reduced between 2002 to 2012 but increased between 2012 to 2023 Accuracy assessment for the land use land cover classes for 2002 was 85.45% with a Kappa coefficient of 0.756, 2012 was 83.64% with a Kappa coefficient of 0.5454 while 2023 was 81.82% with a Kappa coefficient of 0.6034 for the land use land cover classes revealing that the classification is accurate. The study revealed that LULCCs are driven by settlement, poverty and climate change mostly thus affecting cropland vegetation and soil fertility majorly. The study concluded that LULCC drivers varied from location to location even within the sub county. The study recommends creation of awareness of understanding the various drivers of LULCCs and impact of each on land quality.

Comparison of two isotopic hydrograph separation methods in the Hydrological Open Air Laboratory, Austria

AbstractExploring the contributions of new and old water to runoff during precipitation events in agricultural catchments is essential for understanding runoff generation, solute transport, and soil erosion. The aim of this study was to investigate the variability in the isotopic composition of precipitation and runoff in the 66 ha agricultural catchment in Austria, in the Hydrological Open Air Laboratory (HOAL), in order to compare two isotope hydrograph separation methods. The classical two‐component (IHS) and the ensemble hydrograph separation (EHS) were applied to multiple large events in May–October of 2013–2018 using δ18O and δ2H. The peak flow new water contributions obtained by IHS were compared with the average new water fraction from EHS. The average new water fraction calculated with EHS based on regular weekly sampling was close to zero, which can be explained by the large diffuse groundwater discharge into the stream between the events. When only investigating events with high temporal resolution sampling, the results suggest that EHS provided average new water fractions during peak flows (0.46 ± 0.04 for δ18O, 0.47 ± 0.03 for δ2H) that were close to the averages obtained by IHS (0.47 for δ18O, 0.50 for δ2H). New water fractions tended to be higher for larger rainfall intensities. High peak flow new water fractions could be explained by the agricultural land use and soils with low permeability promoting overland flow generation and by some of the tile drainage systems contributing to the delivery of water. In conclusion, a weekly sampling frequency was not sufficient in the HOAL but instead high‐resolution sampling during events was necessary to estimate the average new water contributions during events. While EHS may be a more robust approach compared to IHS, as it relaxes some of the assumptions of IHS, IHS can provide information on the variability of new water contributions of individual events.

Assessment of Heavy Metals Using the Enrichment Factor and Geoaccumulation Index in Menjer Lake, a Tropical Volcanic Lake

Lakes are recognized as vulnerable to pollution, including Menjer Lake, whose catchment area is dominated by agricultural lands and features floating net cages in the water body. The heightened contamination risk within the lake primarily stems from the accumulation of heavy metals, compounds known for their profound toxicity. The high-level concentration of heavy metal in sediment aligns with the level of water toxicity, underscoring the urgent need for thorough assessment and monitoring. The research focused on assessing heavy metal concentration and distribution through spatial analysis. Toxicity levels were evaluated using the enrichment factor (EF) and Geoaccumulation Index (Igeo). This study collected eight samples each during the rainy season of 2022 and 2023. The heavy metals were tested using an Atomic Absorption Spectrophotometer (AAS), including Pb, Cd, Cr, Fe, Al, and Cu. Comparatively, the mean concentration of heavy metals in 2023 was slightly higher for Fe and Al than in 2022. Moreover, Cd was not detected in either 2022 or 2023. The variety of land use and land cover has consequences on the spatial distribution of toxicity levels, showing an influential correlation between Al, Pb, and Fe metals with locations associated with cropland and floating net cages. Additionally, highly steep slopes significantly affected erosions that induced sediment from agricultural land use, further underscoring the multifaceted nature of environmental risk factors.

Ландшафтно-экологическое территориальное зонирование (на материалах Акмолинской области)

Introduction. Modern human activities in nature are subject to increasing regulation and restrictions, which should be reflected in systems for the use of natural resources, primarily in agricultural production. The problem under consideration is of particular relevance for the regions of Northern Kazakhstan, since the natural landscapes of the region have been radically changed and transformed into natural and agricultural complexes with a disturbed landscape-ecological balance.From the point of view of modern natural science, the organization of the rational use of rural areas should be solved by applying a concept based on the landscape-ecological approach. The purpose of the study. Territorial zoning of the agricultural landscape to optimize the use of agricultural land based on the landscape-ecological approach. Research methods. Cartographic materials used as the basis for the creation of diagrams and design developments, obtained on the basis of data from the virtual information system of the land cadastre of the Republic of Kazakhstan and processed using the ArcGIS program. Research results. Based on materials from the steppe zone of the Akmola region of the Republic of Kazakhstan, an analysis of landscape conditions and ecological stability of agricultural landscape systems was carried out. Analysis of territorial landscape zoning allowed us to conclude that the predominant part of the field landscapes of the steppe eons of this region is occupied by natural-territorial complexes of watershed spaces and watershed slopes, and the most common form of relief is slope surfaces. Ecological zoning of agricultural landscapes in the Akmola region revealed that the most common agricultural landscapes are characterized by weak stability and unstable agricultural landscapes. The article proposes a methodology for territorial zoning of agricultural lands on a landscape-ecological basis in the conditions of the Akmola region. It includes the following procedure: drawing up a landscape map. identification of homogeneous ecological zones; agrolandscape microzoning. As a result of research at the research object, a scheme of territorial landscape-ecological zoning for land use of agricultural formations was compiled, which is based on taking into account the paradynamic landscape structure of steppe landscapes and the degree of their anthropogenic transformation. At the same time, relatively homogeneous landscape-ecological microzones were identified, within which the elementary landscapes of the steppe catena were differentiated according to measures that stabilize the stability of the agricultural landscape. Conclusions. 1. On the territory of the Akmola region, natural landscapes have been transformed into agricultural production modifications. with a low degree of sustainability, requiring measures to maintain landscape-ecological balance. 2. The methodology for territorial zoning of steppe agricultural landscapes should be based on taking into account the paradynamic landscape structure of steppe landscapes, i.e. its catenary device. 3. Application of the results of territorial landscape-ecological zoning in design developments for the use and protection of land will allow the selection of optimal directions that ensure the sustainability of agricultural landscapes.

농지제도의 개선을 통한 농업경쟁력 강화 방안

1. CONTENTS (1) RESEARCH OBJECTIVES In order to strengthen agricultural competitiveness, the average production cost of agricultural products should be lowered by expanding the arable area per farm, and for this, the farmland ownership system needs to be reorganized. (2) RESEARCH METHOD This study has been mainly studied in the literature study. It analyzes using various statistics and articles related to farmland ownership system. (3) RESEARCH FINDINGS It seems reasonable to regularize the survey on farmland use, and the Korea Rural Community Corporation should have an organization of farmland bank managers along with the farmland bank system to oversee the survey. 2. RESULTS It is necessary to revitalize the farmland banking system that manages farmland transactions, leases, and farmland information as improvement measures and policy tasks for farmland acquisition qualifications and farmland ownership limits. In addition, farmland in agricultural promotion areas and agricultural protection areas should be suppressed for other purposes as much as possible, and the principle of cultivation should be maintained in a declarative sense, but more prospective farmland ownership and lease policies are required to expand the size of farming.
