| Résumé: | Drought is one of the most serious climatic and natural disasters inflicting serious impacts
on the socio-economy of Morocco, which is characterized both by low-average annual rainfall and
high irregularity in the spatial distribution and timing of precipitation across the country. This work
aims to develop a comprehensive and integrated method for drought monitoring based on remote
sensing techniques. The main input parameters are derived monthly from satellite data at the national
scale and are then combined to generate a composite drought index presenting different severity
classes of drought. The input parameters are: Standardized Precipitation Index calculated from
satellite-based precipitation data since 1981 (CHIRPS), anomalies in the day-night difference of Land
Surface Temperature as a proxy for soil moisture, Normalized Difference Vegetation Index anomalies
from Moderate Resolution Imaging Spectroradiometer (MODIS) data and Evapotranspiration
anomalies from surface energy balance modeling. All of these satellite-based indices are being used
to monitor vegetation condition, rainfall and land surface temperature. The weighted combination
of these input parameters into one composite indicator takes into account the importance of the
rainfall-based parameter (SPI). The composite drought index maps were generated during the
growing seasons going back to 2003. These maps have been compared to both the historical, in situ
precipitation data across Morocco and with the historical yield data across different provinces
with information being available since 2000. The maps are disseminated monthly to several main
stakeholders’ groups including the Ministry of Agriculture and Department of Water in Morocco. |
