Evaluation des Actifs durables (SAVi) du Delta du Saloum au Sénégal

The report uses the Sustainable Asset Valuation (SAVi) methodology to quantify the economic contribution of the Saloum Delta's wetlands and mangroves. It compares a 'business-as-usual' (BAU) scenario with interventions such as organic farming, mangrove reforestation, solar cookers, road construction, and oil extraction. The analysis highlights a tension between long-term natural capital gains and short-term industrial revenues, specifically noting that while oil extraction generates high direct income, it severely degrades ecosystem services. The document proposes blended finance mechanisms, including carbon offsets and impact bonds, to incentivize conservation.

• The Saloum Delta provides significant ecosystem services, with a cumulative value of 964 billion CFA francs between 2019 and 2029.
• Mangrove reforestation is highly beneficial for ecosystem performance, with an estimated increase in value of over 257,000 million CFA francs (approximately 391 million euros).
• Oil extraction generates substantial direct revenue but causes high negative impacts on the ecosystem services of the delta's wetlands and mangroves.
• Solar cookers are highly effective at reducing greenhouse gas emissions, reducing the social cost of carbon by more than 33,000 million CFA francs (50 million euros).
• Organic farming improves the performance of wetland ecosystem services by approximately 128,530 million CFA francs while increasing production and employment.
• Road construction increases labor income across economic sectors but accelerates deforestation near the roads, increasing pressure on natural capital.
• In a business-as-usual (BAU) scenario, the cost of constructing infrastructure to replace the nutrient removal service provided by the delta would be 1,503 billion CFA francs over 10 years and 3,648 billion CFA francs over 40 years.
• The report identifies several potential blended finance strategies to support conservation, including carbon offsets, biodiversity credits (Wetland Banks), performance-based payments, and pay-as-you-go initiatives for solar appliances.
