Abstract:

Malaria is a major health problem in most of sub-Saharan Africa, including Ethiopia. In Ethiopia 68% of the population are at risk of malaria. Anopheles arabiensis is the major vector for malaria transmission in the region. The aim of this study is to develop a model of potential vector breeding sites based on ecological and climatic factors using satellite observations. Remote sensing data from Landsat TM were used to generate vegetation indices (NDVI and EVI) and normalized difference water index (NDWI) at 30m spatial resolution. Multi-temporal Landsat TM scenes were used to identify aquatic habitat sites using supervised classification techniques. A 30 meter SRTM data was used to generate elevation, slope, flow accumulation, and topographic wetness indices. These ecological and physiographic factors were included as input parameters in our model. We used overlay techniques in a GIS platform to develop a final model of Anopheles arabiensis breeding habitat potential. Results highlight specific areas of the region that are classified as potential breeding habitat for the malaria transmitting vector. These vector habitat suitability maps will help decision makers to plan follow-up studies and implement cost effective vector control strategies in the Amhara region of Ethiopia.
