Based on the results of the analysis of changes in agricultural land use for mendong crops in Blayu Village in 2010-2024, an increase in changes in the area of ​​mendong crops was obtained by 26.45 ha or 91.4 %. Meanwhile, the factors causing changes in the use of agricultural land for mendong plants in Blayu Village are economic factors, labor, mendong craftsmen, and the availability of mendong plant drying equipment.

Agricultural Runoff Effects on Leaf Litter Decomposition: A Comparative Study in Natural and Constructed Deltaic Mediterranean Wetlands

Wetlands, widely distributed and hotspots of biodiversity, play a crucial role in global biogeochemical cycles and human well-being. However, despite their ecological importance, wetlands worldwide are under threat due to widespread conversion into agricultural fields, leading to changes in hydrology, increased salinity, and more frequent eutrophication. In response to these challenges, constructed wetlands are created to treat agricultural wastewater and mitigate eutrophication. This study aims to assess the effect of natural vs. constructed wetlands on ecosystem functioning (organic matter decomposition of the dominant vegetation: Phragmites australis and Typha angustifolia). We conducted this study in the Ebro River Delta (NE Spain), which represents a deltaic wetland affected by agricultural land-use changes, examining two constructed and two natural wetlands. Our findings indicate that the influence of agricultural runoff on the decomposition process was similar in both types of wetlands, suggesting that freshwater agricultural runoff has a consistent effect on ecosystem functioning, regardless of its origin, natural vs. constructed. Differences in macroinvertebrate communities associated with leaf litter were likely due to specific conductivity but did not impact decomposition rates. The estimated time required to decompose 95% of the T. angustifolia litter produced annually in the studied wetlands ranged from 288 to 856 days. In constructed wetland, this decomposition time exceeded one year, contributing to soil formation and carbon sequestration in wetland ecosystems. Our study suggests that the utilization of constructed wetlands for treating agricultural runoff can aid in mitigating the impacts of agricultural land use in these areas.

The centennial legacy of land-use change on organic carbon stocks of German agricultural soils.

Converting natural vegetation for agriculture has resulted in the loss of approximately 5% of the current global terrestrial soil organic carbon (SOC) stock to the atmosphere. Increasing the agricultural area under grassland may reverse some of these losses, but the effectiveness of such a strategy is limited by how quickly SOC recovers after conversion from cropland. Using soil data and extensive land-use histories gathered during the national German agricultural soil inventory, this study aims to answer three questions regarding agricultural land-use change (LUC): (i) how do SOC stocks change with depth following LUC; (ii) how long does it take to reach SOC equilibrium after LUC; and (iii) what is the legacy effect of historic LUC on present day SOC dynamics? By using a novel approach that substitutes space for time and accounts for differences in site properties using propensity score balancing, we determined that sites that were converted from cropland to grassland reached a SOC equilibrium level 47.3% (95% confidence interval (CI): 43.4% to 49.5%) above permanent cropland levels 83 years (95% CI: 79 to 90 years) after conversion. Meanwhile, sites converted from grassland to cropland reached a SOC equilibrium level -33.6% (95% CI: -34.1% to -33.5%) below permanent grassland levels after 180 years (95% CI: 151 to 223 years). We estimate that, over the past century, today's German agricultural soils (16.6 million ha) have gained about 40 million Mg C. Furthermore, croplands with historic LUC from grassland are losing SOC by -0.26 Mg ha-1 year-1 (10% of agricultural land) while grasslands historically converted from cropland are gaining SOC by 0.27 Mg ha-1 year-1 (18% of agricultural land). This study shows that even long-standing temperate agricultural sites likely have ongoing SOC change as a result of historical LUC.

Spatial examination of social and environmental drivers of Middle East respiratory syndrome coronavirus (MERS-CoV) across Kenya.

Climate and agricultural land-use change has increased the likelihood of infectious disease emergence and transmissions, but these drivers are often examined separately as combined effects are ignored. Further, seldom are the influence of climate and agricultural land use on emerging infectious diseases examined in a spatially explicit way at regional scales. Our objective in this study was to spatially examine the climate, agriculture, and socio-demographic factors related to agro-pastoralism, and especially the combined effects of these variables that can influence the prevalence of Middle East respiratory syndrome coronavirus (MERS-CoV) in dromedary camels across northern Kenya. Our research questions focused on: (1) How MERS-CoV in dromedary camels has varied across geographic regions of northern Kenya, and (2) what climate, agriculture, and socio-demographic factors of agro-pastoralism were spatially related to the geographic variation of MERS-CoV cases in dromedary camels. To answer our questions, we analyzed the spatial distribution of historical cases based on serological evidence of MERS-CoV at the county level and applied spatial statistical analysis to examine the spatial relationships of the MERS-CoV cases between 2016 and 2018 to climate, agriculture, and socio-demographic factors of agro-pastoralism. Regional differences in MERS-CoV cases were spatially correlated with both social and environmental factors, and particularly ethno-religious camel practices, which highlight the complexity in the distribution of MERS-CoV in dromedary camels across Kenya.

Detection of Urban Growth in Taiz City, Yemen, Between 1981 and 2022 by Using Google Earth™ and Geographical Information System Data

Rapid urbanization brought serious socio-economic and environmental problems in many cities around the world, particularly in developing countries like Yemen. Urban "sprawl", a synonym of rapid and unplanned urban growth, is considered an obstacle for sustainable development, which causes serious long- and short-term problems, such as extreme infrastructure expenses, economic inefficiency, environmental destruction, and social instability. This is the case of Taiz City, the third largest city in Yemen, which is facing a huge challenge to manage the spatial extension of its built-up area at the expense of the reduction of natural resources and environment. This study aims to investigate urban growth process in Taiz City, focusing on urban sprawl and agricultural land-use change during 1981–2022. The data used are high resolution geospatial data, which are the topographic map for 1981 and Google Earth (GE) images for 2003, 2012, and 2022. The methodology adopted was manual digitizing using Geographic Information System (GIS) software to extract urban land use features from the images of the different dates. Four land-use maps were produced and used for calculation the urban sprawl and land-use changes. The urban expansion rate and patterns were also identified in three phases: 1981–2003, 2003–2012, and 2012–2022. The results show that the built-up area increased six times from 6.2 km2 in 1981 to 34 km2 in 2022, while the agriculture area decreased by 77% from 18 km2 in 1981 to 4.2 km2 in 2022. The urban sprawl in Taiz covered about 75% of its municipal area and extended to the agricultural and rural areas. The sprawl index (USI) is measured to be 5.4%, indicating a high degree of sprawl in Taiz. There is no open space left for future development, and the water resources are at risk of population and depletion. The study demonstrated that informal and haphazard expansion must be controlled, a development strategy should be prepared, so that sustainable urban growth can be achieved. The results of this study could be used as a decision support tool for urban management activities. The vector layers produced by this study could provide the required input data for the future urban modeling of the city.

Assessing the trends and drivers of agricultural land use change in the Ramsar County, northern Iran

Agricultural land use change (ALUC) is a primary driver of global environmental change, with implications for food security and the environment. Ramsar County in the north of Iran has continuously undergone many changes due to the tourism characteristics of the region. The present study demonstrates the ALUC trends from 1992 to 2022 and the main drivers affecting ALUC in Ramsar County, northern Iran, using household surveys and Landsat data. Six land use classifications have been made for the region by image processing. Images have been categorized using the maximum likelihood classifier. Likewise, utilizing a questionnaire from 200 randomly selected farmers, in-person interviews were conducted. The kappa coefficient and overall accuracy for 1992, and 2022 were 85.91%, 88.86%, and 88.38%, 90.83%, respectively. It was observed that from 1992 to 2022, orchard (12%), open land (4.8%), and built-up areas (160.5%), increased respectively. In contrast, forest (−12.1%), water (−82.6%), and agri-land (−14.8%), declined respectively. Additionally, the analysis of the household survey indicates the high cost of production, the lack of a suitable market and price fluctuations of products, the aging of farmers, the increase in the population of non-native residents, weak policies to support farmers, lack of coordination between relevant institutions, the beautiful nature and tourism of the region, and climate changes and drought in other parts of the country were the most important drivers affecting ALUC in the region. Overall, this study can provide significant insights to decision-makers at the beginning of strategic planning to control the ALUC in the region.

Persisting in a transformed landscape: occupancy and habitat association of the range-restricted Agulhas Long-billed Lark Certhilauda brevirostris

ABSTRACT We investigated how the presence of the highly range-restricted Agulhas Long-billed Lark Certhilauda brevirostris (ALBL) varies with vegetation type and landscape features. The lark’s distribution is nearly completely outside formally protected areas and overlaps with a region where agriculture has transformed the landscape, with very little of the original vegetation type remaining. Establishing important habitat requirements is needed to better manage conservation efforts for the species. We conducted 10-minute point counts at 51 sites along small rural roads quarterly between October 2020 and January 2022, and recorded ALBL in 58% of the counts. A subset of 45 sites was used to model occupancy. According to a null constant parameter model, occupancy at sample sites was high (0.91) with a detection probability of 0.67 for each site where the species was present. Modelling of habitat features and vegetation type found that ALBL occupancy was best explained by the presence of renosterveld, the shrubby indigenous vegetation type. Occupancy increased at a site up to 25% renosterveld cover, after which there was no effect. Occupancy was also positively associated with renosterveld vegetation presence along fence lines and a combination of renosterveld and decreasing riverine vegetation cover. Presence was little modified by seasonal changes in agricultural land use. Overall, our results suggest that although the ALBL is locally abundant, certain habitat features need to be preserved to ensure the species’ continued presence in this agricultural region.

ASSESSING THE IMPACT OF LAND COVER AND LAND USE CHANGE ON URBAN INFRASTRUCTURE RESILIENCE IN ABUJA, NIGERIA: A CASE STUDY FROM 2017 TO 2022

The remarkable feature of rapid urbanisation, which has fundamentally altered the distribution of land cover and land use (LULC), is what sets the contemporary era apart. The impact of these modifications on the resilience of Abuja’s metropolitan infrastructure from 2017 to 2022 is examined in this study. Our study examined the dynamic changes in LULC using information from remote sensing, geospatial analysis software, and land cover categorization techniques. The findings indicate major changes in Abuja’s topography, including a decrease in the number of water bodies, a decrease in the number of trees, the expansion of urban areas, changes in agricultural land use, and fluctuations in the amount of grazing land. The previously mentioned changes have significant consequences for urban infrastructure resilience, affecting various sectors such as water supply, transportation, housing, utilities, and food distribution systems. The infrastructure supporting water supply and sanitation may be severely stretched as the number of water bodies decreases, affecting the quantity and quality of accessible water supplies. As metropolitan areas expand, greater strain is placed on transportation infrastructure, exacerbating traffic congestion and complicating road maintenance ifficulties. Changes in agricultural land use can have an impact on food production and distribution, hence affecting food security. Deforestation can cause ecological deterioration, affecting a variety of aspects such as temperature regulation, biological diversity, and atmospheric purity. Adaptive approaches, green infrastructure, and adopting sustainable urban design can all strengthen the resilience of urban infrastructure, according to this study. The significance of renewable energy adoption, community participation, green building laws, the establishment of public-private partnerships, integrated water resource management, and data-driven decision-making is emphasised. Improving legal frameworks that prioritise resilience and sustainability is critical. It is critical to have a complete grasp of the complicated links between changes in LULC, and the resilience of urban infrastructure in order to enable educated urban design and decision-making processes. Policymakers and urban planners may address and minimise the negative consequences of climate change while improving the overall quality of life in cities by using sustainable development practises. The findings of this study have the potential to dramatically improve Abuja’s people’s well-being and sustainability, especially given the variety of urban difficulties they encounter.

Saltwater Intrusion and Agricultural Land Use Change in Nga Nam, Soc Trang, Vietnam

Under the effects of saltwater intrusion from rising sea water levels, climate change, and socioeconomic issues, the Nga Nam district in Vietnam has suffered damage to its agriculture and changes in agricultural land use. This study aimed to investigate the factors that influenced land use changes and to propose approaches to limit the changes in agricultural land use. The damage caused by saltwater intrusion on agricultural production was evaluated via the use of secondary data collected from the Department of Infrastructure Economics of the Nga Nam district in the period of 2010–2021. The results show that during the 2010–2015 period, agricultural production areas were affected in 2010, 2012, and 2015. In the period of 2015–2021, the trend of saltwater intrusion along the damaged area remarkably decreased due to the work of saltwater-preventing structures. In this period, the area of annual plants increased, while that of fruit trees decreased. In the area comprising annual plants, the area using the triple rice land use type converted into an area using the double rice and double rice–fish ones. Lands for fruit trees transitioned from mixed farming to specialized farming to raise the economic efficiency for farmers. These changes were affected by four main factors: the physical factor, the economy, society, and the environment. The environmental and economic factors were seen to play the most important role as drivers of changes in land use. The factors of saltwater intrusion and acid-sulfate-contaminated soil, consumer markets, floods, drought, profit, and investments were noted to be significant drivers in agricultural land use change. Thus, both structural and non-structural approaches are suggested to inhibit the safeguard changes in the future.

Past anthropogenic land use change caused a regime shift of the fluvial response to Holocene climate change in the Chinese Loess Plateau

Abstract. The Wei River catchment in the southern part of the Chinese Loess Plateau (CLP) is one of the centers of the agricultural revolution in China. The area has experienced intense land use changes since ∼6000 BCE, which makes it an ideal place to study the response of fluvial systems to past anthropogenic land cover change (ALCC). We apply a numerical landscape evolution model that combines the Landlab landscape evolution model with an evapotranspiration model to investigate the direct and indirect effects of ALCC on hydrological and morphological processes in the Wei River catchment since the mid-Holocene. The results show that ALCC has not only led to changes in discharge and sediment load in the catchment but also affected their sensitivity to climate change. When the proportion of agricultural land area exceeded 50 % (around 1000 BCE), the sensitivity of discharge and sediment yield to climate change increased abruptly indicating a regime change in the fluvial catchment. This was associated with a large sediment pulse in the lower reaches. The model simulation results also show a link between human settlement, ALCC and floodplain development: changes in agricultural land use led to downstream sediment accumulation and floodplain development, which in turn resulted in further spatial expansion of agriculture and human settlement.

Does Rhizobial Inoculation Change the Microbial Community in Field Soils? A‍ ‍Comparison with Agricultural Land-use Changes.

Although microbial inoculation may be effective for sustainable crop production, detrimental aspects have been argued because of the potential of inoculated microorganisms to behave as invaders and negatively affect the microbial ecosystem. We herein compared the impact of rhizobial inoculation on the soil bacterial community with that of agricultural land-use changes using a 16S rRNA amplicon ana-lysis. Soybean plants were cultivated with and without five types of bradyrhizobial inoculants (Bradyrhizobium diazoefficiens or Bradyrhizobium ottawaense) in experimental fields of Andosol, and the high nodule occupancy (35-72%) of bradyrhizobial inoculants was confirmed by nosZ PCR. However, bradyrhizobial inoculants did not significantly affect Shannon's diversity index (α-diversity) or shifts (β-diversity) in the bacterial community in the soils. Moreover, the soil bacterial community was significantly affected by land-use types (conventional cropping, organic cropping, and original forest), where β-diversity correlated with soil chemical properties (pH, carbon, and nitrogen contents). Therefore, the effects of bradyrhizobial inoculation on bacterial communities in bulk soil were minor, regardless of high nodule occupancy. We also observed a correlation between the relative abundance of bacterial classes (Alphaproteobacteria, Gammaproteobacteria, and Gemmatimonadetes) and land-use types or soil chemical properties. The impact of microbial inoculation on soil microbial ecosystems has been exami-ned to a limited extent, such as rhizosphere communities and viability. In the present study, we found that bacterial community shifts in soil were more strongly affected by land usage than by rhizobial inoculation. Therefore, the results obtained herein highlight the importance of assessing microbial inoculants in consideration of the entire land management system.

Potential Changes in Land Use and Plant Production in Poland in the Context of Implementing the European Green Deal

The purpose of this paper is to identify the potential changes in agricultural land use in Poland as a consequence of implementing the European Green Deal, including its potential economic effects. The study covered crops of key importance to Polish agriculture, cultivated in a total area of 8.2 million ha, which accounts for more than 60% of land in good agricultural condition. The analyses were based on average values for 2016–2020 and used three scenarios for EGD implementation by 2030 (no EGD; partial implementation of the EGD; full implementation of the EGD). Each analysis took account of changes in the area of land under conventional, organic and precision farming systems. The study found that EGD requirements can be met by implementing the precision farming system, especially for intensive farming schemes like rape and sugar beet. Organic farming should be used either for extensively farmed cereals like oat or for fruits which are sold at higher prices when farmed organically. Another finding is that the full implementation of the EGD could decrease the production volume of key Polish crops by 13%, which can have important social impacts, such as increased prices of food products or a deterioration of food security.

Forest fires social and climate change in Cyprus

Forest fires and wildfires are increasing in many regions of the world and give the big impact on the environment, local economies, livelihoods, and societies. Cyprus is an island member of the European Union in the south-eastern Mediterranean and it is severely affected by wild fires. The aim of this paper is to review the pertinent, recent literature (which although not exhaustive, identifies the main contributing factors) mostly in the Mediterranean region and to identify the variables that affect the rise in the number and intensity of forest fires, wildfires and how these variables are affecting Cyprus. This research was conducted by using statistical data made by the Cyprus Statistical Service. By compiling the data of climatology, demography, agricultural production, and forest fire incidents, some results were found. The increased forest fires were caused by the rise of the average annual mean temperature in the period of 1990-2021, the change in social conditions and agricultural land use with the urbanization of people living around the forest areas, and the conservative policies adopted by successive administrations with reference to forest management and conservation.

ANALYSIS OF RICE CROP PRODUCTION CHANGES DUE TO LAND USE CHANGES IN BAGIK POLAK VILLAGE, LABUAPI SUBDISTRICT WEST LOMBOK REGENCY

Bagik Polak Village is located in Labuapi District, West Lombok Regency. Its area is 2.50 km2 with 7 sub-villages and a population of 4,232 people and a population density of 1,693 people/km2. Geographically, Bagik Polak is located at coordinates 8037'39" S 116007'57" E. Agricultural activities such as planting rice, corn, horticulture, and livestock, are mostly carried out by the community to meet the needs of life. However, in the last 10 years, there has been a change in the function of agricultural land to non-agricultural land. An increase in population causes this, the dynamics of development and industrial development, which require space, so it has implications for changes in land use. The purpose of this study is to analyze changes in rice crop production based on land use changes in Bagik Polak Village from 2012 to 2022. The method used in this study is the evaluative descriptive method. Data processing and analysis is carried out using ArcGis 10.8, while the stages include geometric correction, image interpretation, calculating the digitized area and field observation. The data used are Google Earth Pro satellite imagery data from 2012-2022 and rice crop production data from 2012-2022. The analysis results show that changes in the use of agricultural land into settlements and housing are the most significant changes. In 2012 the area of agricultural land was 189.51 Ha with rice production of 11.867813 quintals. However, in 2022, the area of agricultural land decreased to 168.32 Ha with rice production of 11.571725 quintals. The average rate of shrinkage of rice crop production is -0.854782108. The land conversion is the main factor causing the decline in rice crop production in Bagik Polak Village. A correlation was found between changes in agricultural land use and a decrease in rice production in Bagik Polak Village, where changes in land use were directly proportional to a decrease in rice production

Sustainability of Informal Artisanal Mining in the Peruvian Andean Region

The purpose of this article is to reflect on the sustainability of informal artisanal mining in the Peruvian Andean area until the year 2022. The research is basic and non-experimental in design and ex post facto in scope. The sample consisted of crime prevention statistics on socio-environmental conflict from guardianship institutions and a television program on mining. Our research procedure focused on gathering secondary information for a documentary review analysis based on past proven and disseminated facts. Informal artisanal mining is strengthened in the Peruvian Andean area due to the following influencing factors: support represented as the social license granted by communal assemblies; the flexibility of governmental management in relaxing compliance related to formalization and preventive laws regarding environmental protection; the resistance to formalization and the 50% increase in socio-environmental conflict; and the 25% increase in production costs related agricultural activities, which promotes the displacement towards mining activities. The environmental sustainability consequences are as follows: limited reconversion of agricultural land-use change in one-third of the communal territories at the headwaters of the basin, which generates the displacement of environmentally friendly economic activity, and a parallel positive action is the impossibility of modification or intervention affecting water surfaces and wetlands due to communal agreements that mining companies must respect during operation.

MAIN CHANGES IN AGRICULTURAL LAND USE IN BULGARIA

The present study examines the changes in the use of different types of agricultural land in Bulgaria during the period from 2007 to 2021. The analysis of their dynamics makes it possible to reveal some factors that influence the course of development of Bulgarian agriculture. From the beginning of the considered period until 2014, there is a clear tendency to decrease the area with agricultural purpose in the country. This reduction is mainly due to a reduction in uncultivated land. These lands represent abandoned perennials and unused arable land for more than five years. The decline of these lands is usually related to factors such as urbanization and non-agricultural land use. Unlike uncultivated land, the size of the country's utilized agricultural area hardly changed over the period.The agricultural area in use covers arable land, perennial crops, nurseries, permanent grass areas and family gardens. There is a significant dynamic in the occupation of the listed types of land during the period, which is more pronounced until 2014. The greatest decrease as an absolute value within the framework of the used agricultural land is in permanently grassed areas. They decreased by almost 480,000 ha from 2007 to 2014. As a relative value, the largest decrease was for vineyards. They are halved over the covered period. Weaker downward changes are reported for family gardens and mixed permanent crops (mainly berry crops). There is an increase in the areas with orchards - by about 20% for the period. The largest increase is recorded for arable land - 430 thousand ha. This increase is mainly due to the reduction of permanently grassed areas and vine plantations. The main part of the arable land is occupied by cereals and technical crops, and the share of these plantations increases during the period. Among cereals, wheat has the largest share, while among technical crops - sunflower. Vegetables have an insignificant share in cultivated land.It can be summarized that changes in agricultural land use in Bulgaria from 2007 to 2021 show a complex interplay of factors, including urbanization, land use changes and changes in crop preferences. These trends imply the need to continue the analysis and adaptation of Bulgarian agriculture to ensure sustainable development and economic viability.

Reconstructed Global Invasion and Spatio-Temporal Distribution Pattern Dynamics of Sorghum halepense under Climate and Land-Use Change.

Sorghum halepense competes with crops and grass species in cropland, grassland, and urban environments, increasing invasion risk. However, the invasive historical dynamics and distribution patterns of S. halepense associated with current and future climate change and land-use change (LUC) remain unknown. We first analyzed the invasive historical dynamics of S. halepense to explore its invasion status and expansion trends. We then used a species distribution model to examine how future climate change and LUC will facilitate the invasion of S. halepense. We reconstructed the countries that have historically been invaded by S. halepense based on databases with detailed records of countries and occurrences. We ran biomod2 based on climate data and land-use data at 5' resolution, assessing the significance of environmental variables and LUC. Sorghum halepense was widely distributed worldwide through grain trade and forage introduction, except in Africa. Europe and North America provided most potential global suitable habitats (PGSHs) for S. halepense in cropland, grassland, and urban environments, representing 48.69%, 20.79%, and 84.82%, respectively. The future PGSHs of S. halepense increased continuously in the Northern Hemisphere, transferring to higher latitudes. Environmental variables were more significant than LUC in predicting the PGSHs of S. halepense. Future PGSHs of S. halepense are expected to increase, exacerbating the invasion risk through agricultural LUC. These results provide a basis for the early warning and prevention of S. halepense worldwide.
