Abstract

The occurrence of drought is mainly a climatic phenomenon which cannot be eliminated. However, its effects can be reduced if actual spatio-temporal information related to crop status is available to the decision makers. In this study, it is tried to evaluate the effectiveness of remote sensing and geographic information system techniques in order to monitor the spatial-temporal dimension of drought. This study covers the period from July 27 to August 11, 2014-2019. This study was carried out considering the vegetation changes of the Seyhan Basin between July and August. VCI (Vegetation Condition Index) drought monitoring was performed using 16-day NDVI time series and land cover maps. In this study, NDVI (Normalized Difference Vegetation Index) based equations developed by Kogan were used in drought monitoring. In the result 27 July-11 August 2014 was observed drought than other periods.
