Country Summary

This page presents high-level information for Mauritania's climate zones and its seasonal cycle for mean temperature and precipitation for the latest climatology, 1991-2020. Climate zone classifications are derived from the Köppen-Geiger climate classification system, which divides climates into five main climate groups divided based on seasonal precipitation and temperature patterns. The five main groups are A (tropical), B (dry), C (temperate), D (continental), and E (polar). All climates except for those in the E group are assigned a seasonal precipitation sub-group (second letter).  Climate classifications are identified by hovering your mouse over the legend. A narrative overview of Mauritania's country context and climate is provided following the visualizations.

Mauritania is located on the coast of the West African Sahel and has a total land mass of 1.03 million km2. The Mauritanian economy is largely dependent on mining, fisheries, livestock and to a lesser degree, agriculture.  Mauritania remains one of the Least Developed Countries in the world, with 46.3% of the population living on less than one US dollar a day.  In 2017, the country has a Gross Domestic Product (GDP) of $2.16 billion; it has a population of 4.4 million people with a  population growth rate at of 2.7%. The country has experienced highly volatile, yet positive growth rates since 2010. The country’s GDP is led by agriculture, fishing and forestry, which accounts for 22.9% of GDP and the industry sector (including mining, construction, electricity, water and gas), which contributes 28.7% of GDP. 

Mauritania is divided into two major climatic zones: the Sahara and the Sahel, each with a coastal shade and a continental shade. The coastline for each climatic zone is characterized by relatively high humidity and low diurnal and annual diurnal ties, while the inland areas have larger temperature differences and extreme air aridity, with very low rainfall and high evaporation. Mauritania’s Nationally Determined Contribution was submitted to UNFCCC in 2017.  Its NDC is focused on increasing the country’s resilience to climate change through the promotion of low carbon growth, while also increasing adaptation for low lying coastal areas, upgrading infrastructure and strengthening the country’s food security position.
