Assessing NDVI, Precipitation and Land Surface Temperature for Drought Monitoring in the Amathole District Municipality, Eastern Cape Province
Abstract: 

Reliable drought information is of utmost importance for efficient drought management. South Africa suffers from high rainfall variability in both amount and distribution and thus drought monitoring is a priority in the country. Monitoring of vegetation using time series of satellite data can assist in understanding the variation both intra- and inter-annually. This paper will focus on drought monitoring drought in Amathole District Municipality using remote satellite (Moderate Resolution Imaging Spectroradiometer and Tropical Rainfall Measuring Mission/Global Precipitation Measurement (MODIS and TRMM/GPM) data. The Eastern Cape Province, particularly, the Amathole District Municipality (ADM) has in recent years been frequently declared as disaster area due to persisting drought conditions. Monthly MODIS NDVI images will be used to monitor vegetation condition/stress which is indicative of agricultural drought. To monitor meteorological drought, monthly precipitation data obtained from the National Aeronautics and Space Administration website (https://mirador.gsfc.nasa.gov/) will used to characterize rainfall fluctuation patterns. Lastly, the relationship between the vegetation condition and land surface temperature will be explored. It is envisaged that the results from the study can be used to assist in drought management and enhance capacity building.
