Towards Implementing Nature-Based Solutions in Mauritius

Mauritius faces significant urban climate challenges, particularly pluvial flooding, flash floods, and heat stress, with Port Louis being highly vulnerable due to its geographic location and runoff from surrounding mountains. These issues are expected to worsen as temperatures rise. Nature-based Solutions (NbS)—such as permeable pavements, bioretention systems, rainwater harvesting, green roofs, and reforestation—offer sustainable alternatives to conventional grey infrastructure by reducing flood risks, mitigating heat stress, and providing environmental and social co-benefits, including potential green jobs.

Currently, there is limited implementation of NbS in Mauritius. To advance adoption, the report recommends creating enabling environments, presenting proof of concept, and developing investment cases to attract resources. The National Climate Change Adaptation Policy Framework 2021 can serve as a key leverage point. While NbS show cost-beneficial outcomes, barriers such as social acceptance and limitations under extreme climate scenarios must be addressed. Capacity building and integration into national development strategies are essential for meeting international climate commitments.

This policy brief was developed in the context of the project “Implementation of Urban Nature-based Solutions for Mitigation and Adaptation” funded by the Ministry of Foreign Affairs of Denmark (Danida).
