Impacts Agriculture

The agricultural sector plays a critical role in Mauritania’s food security situation and economic prosperity. The country remains highly food insecure and reliant on external food aid. Agriculture in Mauritania, as in much of the Sahel, is poorly mechanized and almost entirely reliant on the limited and variable summer rainfall, making it highly vulnerable to climate variability and change. In dry years, the region faces serious challenges related to food security and must rely on grain purchases and food aid to meet food requirements. Delayed rains and rain deficits have been particularly pronounced for the country’s agricultural zones in recent years. Mauritanian soils are generally nutrient-limited and at risk of further degradation from deforestation, overgrazing and continuous cropping. Reduced precipitation and higher temperatures is expected to increase desertification and sand intrusion. Land cover changes, primarily deforestation for firewood, also effect the moisture content of the soil and increased water stress is expected to compound reduced crop productivity. 

This section allows you to gain insights into climate change impacts on agricultural productivity indicators. These indicators give a comprehensive view on a country's dependence on agriculture, on three fronts: economically, in terms of dependent population and land resources availability.


Data presented under Historical Climate Conditions are reanalysis products derived from ERA5-Land data. ERA5-Land is a global land-surface dataset at 9 km resolution, consistent with atmospheric data from the ERA5 reanalysis from 1950 onward. Climate reanalyses combine past observations with models to generate consistent time series of multiple climate variables. They provide a comprehensive description of the observed climate as it has evolved during recent decades, on 3D grids at sub-daily intervals. 

This data has been collected, aggregated and processed by the Climate Resilience Cluster of the European Space Agency’s (ESA) Earth Observation for Sustainable Development (EO4SD) initiative.
