Sustainable Asset Valuation of the Nature-Based Infrastructure Transformation Program for Kisumu, Kenya

A Sustainable Asset Valuation (SAVi) assessment of the nature-based infrastructure (NBI) program in Kisumu, Kenya, indicates that an integrated approach combining agroforestry, sanitation, and fisheries could yield USD 940 million in net benefits over 26 years. Key drivers include USD 480 million in avoided health costs from improved sanitation and USD 62.85 million in carbon valuation, which exceeds the program's capital costs.

• The integrated nature-based infrastructure (NBI) transformation program in Kisumu is projected to generate nearly USD 940 million in net benefits over a 26-year period, representing a return of approximately USD 3 in value for every dollar invested.
• Specific components of the NBI program provide distinct economic and health advantages: sanitation measures are estimated to prevent nearly USD 480 million in health costs by reducing waterborne diseases, while fisheries interventions are noted for delivering the highest return per dollar invested.
• Carbon storage from agroforestry and reforestation is valued at USD 62.85 million, an amount that exceeds capital expenditures and suggests that carbon credits could serve as a viable financing tool.
