Drought Impacts III: Agricultural Systems

Description & Learning objectives

Drought is the most important abiotic stressor, influencing cropping systems and consequently, food security. In this webinar, we explain the characteristics and importance of agricultural drought compared to other droughts (e.g. meteorological, hydrological, etc.).

We introduce the capability of global crop water models and remote sensing approaches in the detection of drought signal on specific crops at global and regional scales. After a short overview of available drought indicators, and highlighting the difference between drought and aridity, we present the outcomes of two case studies at different scales. The first case study focuses on spatial pattern, frequency and magnitude of drought across different crops and regions at a global scale. The second case study demonstrates the relationships between simulated (model-based) and remote sensing-based drought indicators at a regional scale. We wrap up the webinar by shortlisting some of limitations and challenges we face in drought monitoring studies.
