Land conversion in Sub-Saharan Africa has profound biophysical, ecological, political and social consequences for human wellbeing and ecosystems services. Understanding the process of land cover changes and transitions is essential for good ecosystem management policy that would lead to improved ...

Rehabilitation of large valley bottom gullies in developing countries is hampered by high cost. Stopping head cuts at the time of initiation will prevent large gullies from forming and is affordable. However, research on practices to control shallow gully heads with local materials is limited. Th...

Monitoring the changes in forest-cover and understanding the dynamics of the forest is becoming increasingly important for the sustainable management of forest ecosystems. This paper uses temporal MODIS Vegetation Continuous Field (MODIS-VCF) to monitor the tree cover change in the Indian region ...

Evaluates relationship between NDVI (nomalized difference vegetation index) and above-ground biomass, between maximum NDVI and end-of-growing season biomass; and between the integral of the NDVI curve or NDVI increments overtime and actual biomass. Describes atmospheric interference and technical...
