Social protection programs: Building the evidence and defining priorities

Social protection programs to reduce poverty, food insecurity, and vulnerability in low- and middle-income countries have become increasingly prominent over the last 50 years. This chapter examines trends in the development of social protection programs and discusses the contribution of research to changing program approaches and social protection policies, highlighting IFPRI’s role in providing evidence and research.

How aid cuts could make vulnerable communities even less resilient to climate change

How aid cuts could make vulnerable communities even less resilient to climate change

As global temperatures rise and climate-related disasters become more frequent, the need to adapt is rapidly increasing. That need for adaptation – from adjusting farming practices to diversifying livelihoods and strengthening infrastructure – is most acute in vulnerable low- and middle-income countries such as Bangladesh, Ethiopia, Haiti and Vietnam.

Building pathways out of poverty in Baidoa: Evidence from a randomized controlled trial at endline

Building pathways out of poverty in Baidoa: Evidence from a randomized controlled trial at endline

Somalia is one of the poorest countries in the world, and severe poverty, ongoing armed conflict, and recurring droughts and floods have created a humanitarian crisis characterized by a high level of inter nal displacement. Baidoa city—the site of this evaluation—hosts 517 sites for internally displaced per sons (IDP), with almost 600,000 households, and 64 percent of the individuals living in these sites are women and girls. According to the second Somali High Frequency Survey (Pape and Karamba 2019), IDP settlements (along with rural areas) face a particularly high level of poverty, exacerbated by high unemployment rates and the absence of income-generating opportunities. This brief reports on endline findings from a randomized controlled trial (RCT) evaluating the project Building Pathways Out of Poverty for Ultra-poor IDPs and Vulnerable Host Communities in Baidoa, an ultra-poor graduation (UPG) intervention implemented by World Vision and funded by the United States Agency for International Development’s Bureau for Humanitarian Assistance (BHA). The project seeks to enable ultra-poor internally displaced households to graduate from extreme poverty and begin the upward trajectory to self-reliance for displacement-affected communities by enabling gender-sensitive, context-appropriate, and sustainable livelihoods in an urban setting. IFPRI is collaborating with World Vision to conduct the trial.
