Rangeland or natural arid pastures of Morocco are defined as ecosystems where
there is a natural or semi-natural vegetation composed of steppes, shrubs and
grassland used mainly for livestock production as climate and soil are unsuitable to
agriculture. The arid rangelands of Morocco occupy an area of over 33 million
hectares between the isohyets of 100 and 400 mm. These areas represent
livelihoods for thousands of people and protect the country from desertification. The
main objective of this study is to provide scientific community and decision-makers
methodological tools for assessing arid rangelands, based on geomatics and
biophysics data.
