The article discusses how Geographic Information Systems (GIS) and remote sensing techniques were used to study the impact of human activities on wetlands in Simuyu basin, Tanzania. By analyzing satellite images from 1973 to 2005, the researchers identified changes in land use patterns that have led to wetland degradation. The study focused on mapping vegetation, land cover changes, and assessing the physical characteristics of the wetland resources. The findings highlight the importance of implementing wise use and conservation strategies to sustain the productivity of wetlands in the area.
