Using geographical information system to generate a drought risk map for rice cultivation: Case study in Babahoyo canton (Ecuador)

Based on Normalized difference vegetation index (NDVI) temporal series and drought claims insurance data, the obtained DRM and DRcM were validated. Both maps show a significant relationship between zone classification and NDVI values. However, the DRM adjusted better to insurance data than the DRcM, which does not consider soil variables. The DRM is an effective tool for agricultural risk management decision-making and it serves as an important source of information that could be used for index-based insurance implementation.
