Abstract

The paper deals with the evaluation of agricultural drought in Slovakia by remote sensing data. For this purpose, monthly normalized difference vegetation index (NDVI) values were derived from MODIS spectroradiometer at district level during the time period of 2000 to 2014. Verification was based on correlations with the Palmer drought severity index (PDSI) for twelve sites selected according to limited climatic parameters. Correlations showed a strong relationship (α ≤ 0.1) between NDVI and PDSI values, mainly in the middle of the growing season (June to September). The aim of the paper is testing NDVI as a suitable tool for drought assessment in an agricultural land in Slovakia.
