Dynamics and drivers of land use land cover changes in Bangladesh
Land is scarce in Bangladesh: Bangladesh occupies ~0.03 % of world’s land area, but supports over ~2% of human population. This high population to land ratio, combined with socioeconomic development has placed tremendous pressure on Bangladesh’s land resources for food, feed, and fuel. This study …

Understanding the relationship between land use/land cover and malaria in Nepal
Malaria is one of the leading causes of mortality and morbidity globally. Land use/land cover (LULC) change have been found to affect the transmission and distribution of malaria in other regions, but no study has attempted to examine such relationships in Nepal. Therefore, this study was conducted …

Seasonal hydrologic dynamics under changing climate, land use-land cover and human influence
Climatic changes along with the land use-land cover changes (LULCC) and human impacts significantly modify the hydrologic flow regime of the river basins, affecting water resources and environment from regional to global scale. Aided by satellite data, modeling and understanding of the interactions …

Changing land use / land cover around an urban estuary : implications for ecosystem functioning
The changing spatial and temporal patterns in land use/land cover surrounding Zandvlei estuary were investigated over the period 1944 to 2005. Changes in the extent of four terrestrial and two aquatic land use/land cover categories were mapped from high quality aerial photographs using ArcView GIS. …

Impacts of land use land cover changes in mountainous catchments – a case study of Klaserie Catchment, Mariepskop Mountain
Land use and land cover (LULC) change remains a central driver of ecological transformation, particularly in semi-arid mountainous catchments where terrain complexity, limited data availability, and climate variability intersect with increasing human population and activity. This study examines the …
