Book excerpt: The Regional Network on AIDS, Livelihoods, and Food Security (RENEWAL) was officially launched in 2001 as a joint project of the International Food Policy Research Institute (IFPRI) and the International Service for National Agricultural Research (ISNAR), and was operational in Malawi, Uganda, Kenya, Zambia, and South Africa through most of 2011. RENEWAL is a “network of networks” comprised of national networks of food and nutrition-relevant organizations, along with partners in AIDS and public health practitioners. Its overarching goal is to provide evidence-based research on the linkages between HIV, food security, and nutrition in Sub-Saharan Africa that would inform responses to prevent or mitigate the impact and consequences of AIDS. RENEWAL’s three main objectives are: (1) to reduce critical gaps in understanding how livelihoods, particularly those deriving from agriculture, both contribute to the spread of HIV and are affected by HIV and AIDS; (2) to generate new policy-relevant knowledge on how households and communities may strengthen both their resistance to HIV transmission and their resilience to the impacts of AIDS; and (3) to enable relevant institutions (particularly governments) to generate and act upon realistic priorities for responding to the interaction of the AIDS epidemic with food and nutrition insecurity. RENEWAL’s strategic approach to achieving these goals involved the three core pillars of capacity strengthening, policy communications, and action research, and the synergies resulting from their interactions. This report assesses the impact of RENEWAL activities from 2000 to 2010 and is based on a review of products resulting from RENEWAL activities (such as books, policy briefs, workshop summaries, reports, and discussion papers), stakeholder perceptions of RENEWAL products and activities, and national policy or programming changes resulting from RENEWAL-supported action research, capacity strengthening efforts, and policy communications.
