The objective of this research study is to investigate the capabilities of time -series of MODIS imagery to provide information on soil erosion at the Kenyan coast.
Soil erosion has been a major environmental threat to sustainability and productive capability
of agriculture over the past few decades: The Kenyan government has been forced to increase
her revenue allocation in agriculture so as to meet the demand of her ever increasing
population. In fact the current trend shows the per capita food productivity is beginning to decline.
In this project we describe the approach based on time-series MODIS imagery to assess the soil
erosion along the Kenyan coast. Using NDVI values computed from MODIS images taken from
2001 to 2013, at an interval of 4 years. The images shall help us assess the spatial and temporal
dynamics of soil and vegetation both along the Kenyan coast and within Indian Ocean.
The result does not only show decrease in vegetation along the coast but also the presence of
both floating and submerged vegetation in the ocean; an indication of deposit of top fertile
alluvial soil due to soil erosion
