Mauritania, a Sahelian nation, faces severe environmental challenges from recurring droughts, desertification, and climate change impacts on water, agriculture, and food security. With limited data on air quality (stable trend) and sustainability metrics (all N/A), the country has updated its NDC to cut emissions by 11% by 2030 and focuses on adaptation in ecosystems, water, and agriculture. Climate disasters like droughts significantly affect growth, mitigated somewhat by efforts in electricity access and health.
