Reforco da Adaptacao Baseada em Ecossistemas em Ambientes Marinhos e Costeiros na Africa Austral

The document advocates for the adoption of ecosystem-based adaptation (EbA) to protect coastal communities in Southern Africa from climate risks such as cyclones and sea-level rise. It identifies key barriers to implementation, including policy silos, insufficient funding, and lack of community inclusion, and proposes the creation of a regional community of practice to share best practices among SADC member states.

• Coastal and island nations in the SADC region are highly vulnerable to climate risks, including cyclones, flooding, and sea-level rise, a vulnerability worsened by poverty, inequality, and political instability. Between 2021 and 2022, six cyclones hit the SADC region, affecting more than 2.5 million people.
• Ecosystem-based adaptation (EbA) is presented as a cost-effective alternative or supplement to 'grey' engineering solutions, such as seawalls. In Tanzania, a hybrid approach was used, combining a 2,400m concrete seawall with the restoration of 1,000 hectares of mangroves and 2,000 square meters of coral reefs.
• Marine ecosystems provide critical protection and carbon storage; mangroves can store up to five times more organic carbon than upland tropical forests, while coral reefs mitigate wave energy to protect coastal communities from storms and cyclones.
• While funding for adaptation in Africa is insufficient, some SADC countries have used innovative financial models, such as the Seychelles Blue Bond, Debt-for-Nature Swaps, payments for ecosystem services, and the sale of blue carbon credits from mangrove restoration in Madagascar.
• To improve regional coordination, the SAIIA has established a SADC regional community of practice for marine and coastal EbA, involving policymakers, universities, NGOs, the private sector, and representatives of women and youth.
