Procedures for providing grants to community groups for wetland conservation using ecosystems-based adaptations

This framework outlines a process developed in Madagascar for managing finance with local communities to support Nature-based Solutions.

It includes sections on context, the steps to follow before the grant is awarded; target and eligible groups; the amount of budget to be allocated, and the method of payment of funds. It also describes safeguarding and monitoring including the complaints system and annual evaluation.

Plan de rempoissonnement du lac Sofia : Conditions, protocole, conception et mise en oeuvre

In French. This document outlines a protocol for developing a fish restocking plan for Lake Sofia, a freshwater lake in Madagascar.

The aim of restocking is to enhance the ecological dynamics of this freshwater ecosystem and, in turn, strengthen the local livelihoods that depend on it—both directly (such as fishing and papyrus-based crafts) and indirectly (including agricultural irrigation). The document outlines the key steps required for a successful restocking plan, from community consultation and plan development to implementation and long‑term monitoring.

Évaluation préliminaire des impacts écologiques de l’ouverture de la retenue naturelle du lac Sofia en février 2024

(In French) A rapid preliminary assessment of the ecological impacts of dam opening at the outlet of Lake Sofia, Madagascar. This opening resulted in loss of more than 70% of the lake’s freshwater.

Assessments were carried out of avain biodiversity, of sedimentation increases in rice paddies, of changes in lake depth and on the impacts on freshwater vegetation upstream and downstream of Lake Sofia. Recommendations are made on further biological research, on ecological restoration and on logistical and infrastructure considerations

Initial GIS Analysis of Degradation in Lake Sofia and Lake Tseny, Madagascar

Research report on the sources of suspended sediment in Lake Sofia and Lake Tseny, Madagascar. The high amount of suspended sediment, in these freshwater systems is a problem as it limits the growth of healthy populations of macrophytes, invertebrates and fish.

The analysis suggests that the biggest source of this pollution is from erosion and transportation by water. Given the diffuse nature of the sediment sources across catchments, it may be necessary to adapt agricultural practices to reduce sediment influx and protect wetlands.

Rapid Assessment of Wetland Management Issues and Nature-based Solutions in the Crater Lakes around Lake Itasy

A report on diagnostic field visit to assist framing of research questions in the freshwater crater lakes around Lake Itasy, Madagascar. It describes the main land use types (lowland and hillside agriculture, terracing, grazing and agroforestry); it identifies the principal threats to sustainable management of the wetland and gives preliminary recommendations for future research.
