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

The Nature-Based Infrastructure (NBI) transformation program in Kisumu, Kenya, integrates agroforestry, sanitation, and fisheries to restore the Lake Victoria basin. A Sustainable Asset Valuation (SAVi) assessment indicates that an integrated approach could generate USD 940 million in net benefits over 26 years, yielding approximately USD 3 for every dollar invested. Key economic drivers include USD 480 million in avoided health costs through improved sanitation and USD 62.85 million in carbon valuation, which exceeds the program's capital expenditures.

• The integrated 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.
• Improved sanitation and WASH interventions within the program could prevent nearly USD 480 million in health costs by reducing the prevalence of waterborne diseases.
• Carbon storage from reforestation and ecosystem restoration is valued at USD 62.85 million, an amount that surpasses capital expenditures and suggests the viability of carbon credits for financing.
