Sustainable Asset Valuation (SAVi) of Aquaculture in Madagascar

The report analyzes the impact of the Projet d'Aquaculture Durable à Madagascar (PADM) across six regions, comparing extensive rice-fish farming with intensive aquaculture systems. It finds that extensive systems outperform intensive ones by 36% when negative externalities are included in the valuation.

• The Projet d'Aquaculture Durable à Madagascar (PADM), funded by the BMZ and implemented by GIZ, supported 15,815 fish farms across 590 hectares in six target regions: Analamanga, Vakinankaratra, Itasy, Amoron’I Mania, Haute Matsiatra, and Atsinanana.
• Sustainable Asset Valuation analysis indicates that extensive aquaculture systems are on average 36% more effective than intensive systems when accounting for the avoidance of negative externalities.
• Rice-fish systems, which allow carp and tilapia to be farmed in rice paddies, provide symbiotic benefits where rice offers habitat and feed for fish, and fish waste fertilizes the rice; however, only 20% of suitable fields are currently utilized for this practice.
