This study investigates the spatiotemporal dynamics of land use and cover (LULC) change in Saudi cities between 2013 2023. Using Landsat satellite imagery a Maximum Likelihood Classifier, LULC changes are analyzed nine to understand impact Arabia's rapid urbanization following oil crisis. The objectives are: (1) evaluate 2023; (2) explore patterns this period; (3) interpret urban expansion that occurs Arabia light kingdom sustainable development plan. results identifiy four primary models: Urbanization, Vegetation Recovery, Land Degradation, Ecological Transition Models.

This study employed Remote Sensing and Geographical Information Systems to explore the influence of environmental factors human-induced land use/land cover changes on chemistry soda-saline lakes in Northern Tanzania. Satellite-based rainfall data were sourced from Climate Hazards Group Infrared Precipitation with Station (CHIRPS) datasets, temperature obtained MERRA-2. Monthly precipitation, temperature, drought conditions lake watersheds analyzed 1981 2022, while use assessed for 2000, 2014, 2023. Soil types acquired FAO Digital Map World, geological characteristics US Geological Survey database. The findings revealed that region's climate is ideal enhancing evapotranspiration, leading mineral altering lakes. Standardized Evapotranspiration Index increased events basins since 1987, prolonged occurrence between 2000 2017. results also showed region characterized by a variety soil types, including ferric acrisols, chromic cambisols, calcic entisols, inceptisols, eutric fluvisols, distric nitisols, humic mollic andosols, ochric pellic vertisols. Furthermore, distinguished diverse processes, Precambrian-Cambrian tertiary intrusive, triggered volcanic tectonic activity. Land indicated dynamics various classes an overall decrease areas under water bodies (-39.80 %), forests (-22.57 %) bareland (-36.18) agricultural (111.01 built-up (434.72 shrubs grasses (72.77 area coverage over 23 years period (2000-2023). underscores complex interplay variables human activities shaping

Land use conflicts represent an increasing challenge to sustainable development, particularly in regions undergoing rapid urbanization. This study investigated the spatiotemporal dynamics of land and their ecological implications Tianshui City from 1980 2020. The main objectives were identify patterns spatial heterogeneity, explore driving factors behind these conflicts, analyze relationship with risks. results indicate following findings. In terms early changes primarily driven by structural factors, such as topography climate, a Nugget/Still ratio <0.30 observed 2000. After 2000, however, stochastic including average annual urbanization rate increase 5.2% GDP growth 9.1%, emerged dominant drivers, reflected > 0.36. Regarding conflict intensity, high-conflict areas expanded approximately 1110 square kilometers between 2020, predominantly concentrated fertile agricultural Weihe River Basin urban core areas. Conversely, non-conflict zones decreased 38.7%. risk correlation, bivariate LISA cluster analysis revealed significant autocorrelation severe risks (Moran’s I = 0.62, p < 0.01). High-risk clusters transitioning arable built-up increased 23% after Predictions based on future land-use simulation (FLUS) model suggest that 2030, high-intensity will expand additional 16%, leading intensified competition for resources. Therefore, incorporating safety thresholds into planning policies is essential reconciling development conservation, thereby promoting transitions.

The Darfur conflict, which emerged in the early 21st century, represents a multifaceted crisis driven by socio-political and environmental factors, with resource scarcity, exacerbated climate change, playing pivotal role intensifying tensions between agricultural pastoral communities. While change is typically associated adverse outcomes, an analysis of data spanning four decades (1980–2023) reveals contrasting trend increased precipitation, enhanced vegetation, decreased drought frequency recent years. This research explores potential these positive changes to mitigate resource-based conflicts foster political stability as improved conditions are posited create foundation for conflict resolution sustainable peacebuilding. present study integrates trends Enhanced Vegetation Index (EVI) Standardized Precipitation Evapotranspiration (SPEI) examine shifts. EVI data, derived from Moderate Resolution Imaging Spectroradiometer (MODIS) at 250 m resolution, was used assess large-scale vegetation patterns arid semi-arid landscapes. Autoregressive Integrated Moving Average (ARIMA) model employed forecast future precipitation scenarios up year 2034, enhancing understanding long-term climatic trends. Data processing utilized advanced tools, including Google Earth Engine (GEE), ArcGIS Pro (version 3.4), R software 4.3.2). findings reveal significant (33.19%) improvement natural cover 2000 2023, degraded unchanged areas accounting 1.95% 64.86%, respectively. finding aligns marked increase annual reduction intensity over period. Historical SPEI showed persistent events 1980 2012, followed notable decline severity 2013 2024. projections suggest stable trend, potentially supporting further recovery region. These improvements preliminarily linked climate-change-induced increases reductions severity. study’s contribute nuanced interplay dynamics Darfur, offering actionable insights policy interventions aimed fostering peace resilience
