Geospatial land cover change analysis using the CA-Markov chain model in Chikwawa District, Malawi

Chikwawa District has experienced significant urban development, agricultural expansion, and population growth over the years. The study analyzed Landsat Satellite images from 1979, 1995, 2009, and 2023 to assess land use and land cover changes. The CA-Markov chain model, a spatially explicit model that integrates cellular automata and Markov chains, was applied to predict future land use and land cover (LULC) scenarios...

Geospatial assessment of agricultural land expansion and its impact on biodiversity: A systematic review

Agricultural land expansion remains one of the most significant drivers of biodiversity loss globally. Geospatial approaches among other tools can support researchers in understanding the complex impacts of this loss. This systematic review critically analyzes recent scientific advancements in remote sensing, land-use transitions, climate-smart agriculture, and policy frameworks to assess the relationship between...

Comparative analysis of wood fuel energy use in tea processing factories in Rwanda

Tea processing in key producing countries such as Kenya, Sri Lanka, and Rwanda remains heavily reliant on wood fuel, particularly for withering and drying stages. Wood fuel poses significant sustainability challenges despite its widespread use, including deforestation, low energy efficiency, and rising production costs. In Rwanda, where tea is a major export commodity, the inefficient use of wood fuel in processing...
