The project aims towards permanent solutions for monitoring of drought, which is one of the most frequent natural disasters. During several phases we will:

  1. determine and analyse the most suitable and stable drought-related indices based on optical satellite data
  2. develop a method for merging satellite data with ground measurements for an accurate (overall producer’s accuracy of more than 90%), high-resolution detection of drought;
  3. design a prototype system for a comprehensive characterization of drought in agricultural areas at a national level.

We will achieve this by examining, evaluating, and enhancing the satellite data processing techniques; data fusion of high and medium-resolution imagery (downscaling); data fusion of imagery and in-situ data; applying time series analyses and machine (deep) learning to find statistically relevant variables and models to indicate the impacted areas. We shall test the universality, comparability, and practicability of satellite-derived indices for operational use, and propose the most suited ones that can serve as proxies for environmental indicators.

Project steps

The work is divided into five work packages:

•          WP 1: Data collection and synchronization (complete),

•          WP 2: Long-term high-resolution satellite records (90% complete),

•          WP 3: Analysis of agricultural drought indicator time series (90% complete),

•          WP 4: Development of a drought detection model and its verification (20% complete),

•          WP 5: Evaluation of results for practical use (20% complete).
