The note frames Tunisia’s severe water stress and declining reservoir capacity, linking sedimentation and land degradation to reduced rainfall and rising evapotranspiration. It emphasizes NbS as decision-support options to mitigate water scarcity and ecosystem service degradation, highlighting the need for cost-benefit analysis to compare immediate implementation costs with mid- and long-term benefits.","Pub lic Disclosure Authorized Pub lic Disclosure Authorized Pub lic Disclosure Authorized Pub lic Disclosure Authorized  \nMIDDLE EAST AND NORTH AFRICA  \nNature-Based Solutions to the Looming Crisis of Climate Change-Induced Water Scarcity in Tunisia  \nTechnical Note  \nNovember 2024  \nDisclaimer  \nThis work is a product of the staff of the World Bank with external contributions.

This note assesses the impact of climate change on water-related ecosystem services and highlights the cost of inaction. It provides critical insights to support decision-making when implementing nature-based solutions (NbS) to mitigate the severe impacts of water scarcity and the degradation of ecosystem services in Tunisia.  \nThe report was prepared by Sana Bouguerra (Ecosystem Services Modelling Specialist), Mariem Khalfaoui (Agroeconomist), Amos Abu (Senior Natural Resources Management Specialist), SandrineJauffret (Senior Natural Resources Management Specialist) and Phoebe Girouard Spencer (Environmental Economist) . It builds on a series of background papers prepared with other specialists, including Khaoula Khemiri (Hydrologist), Nessrine Zemni (Agronomist), and Hamza Jerbi (Hydrogeologist), as well as the invaluable contributions and guidance from Tijen Arin (Senior Environment Economist), Massimiliano Cali (Senior Economist), and Marcelo Acerbi (Senior Environmental Specialist) .  \nWe would like to thank Marouen Dabbaouni, Aymen Nefzi, Fatin El Euch, Jamel Kailene, Kamel Aloui, and Samir Bel Haj Salah (all Ministry of Agriculture, Water Resources and Maritime Fisheries) as well as Walid Riahi (Ministry of Environment) for their invaluable support and guidance in producing this note.  \nThe World Bank also owes thanks to Carole Megevand (Sector Leader – Planet Department (Agriculture & Food, Climate Change, Environment, Social Development, Water) for The Maghreb and Malta) and Maria Sarraf (Manager, Environment department for the Middle East, and North Africa) for providing substantive orientation for the technical work.  \nThis technical assistance was funded by the Global Program on Sustainability (GPS), an umbrella trust fund that aims to integrate sustainability considerations into policies and decision-making through the provis","cbCaia3GS8dWsM5J","https://ap.wps.com/l/cbCaia3GS8dWsM5J","pdf",4097120,5,1,56,"English","en",105,"# Executive Summary\n## Ecosystem services and water stress context\n## Role of forests and reservoirs\n## Need for cost-benefit analysis and NbS","[{\"question\":\"Why is Tunisia facing increasing water scarcity risks?\",\"answer\":\"Tunisia experiences extremely high water stress, projected to worsen by mid-century.
