Regional Vulnerability Assessment and Analysis (RVAA) The project supports Southern African Development Community (SADC) and its member states in establishing and updating systems for vulnerability assessments and analysis (VAA) providing reliable information on food security situation and related conditions to determine appropriate short-term interventions and long-term policy and projects planning. The project will establish VAA systems in countries without such analyses, update existing systems to integrate climate change with food security and develop capacities for VAA.
