Study prepared by FAO Regional Office for Africa, October 2012
Environmental migration has been the subject of lively debate in recent years. Recent International Food Policy Research Institute (IFPRI) research lets us put this debate into perspective. Microlevel evidence has improved our understanding of how climate affects individual and household decisions to migrate over time in African and Asian countries. Macrolevel analyses help us assess whether such country-specific evidence may be systematic enough to constitute a global phenomenon.
This brief reviews recent evidence, examines main research challenges in identifying migration–climate links and discusses the policy options for formalizing migration as an adaptation mechanism to climate change.
Agnes R. Quisumbing and Scott McNiven, FAO/ESA This paper investigates the impact of migration and remittances on asset holdings, consumption expenditures, and credit constraint status of households in origin communities, using a unique longitudinal data set from the Philippines. The paper examines the impact of remittances from outside the original survey villages on parent households, taking into account the endogeneity of the number of migrants and remittances received to characteristics of the origin households and communities, completed schooling of sons and daughters, and shocks to both the origin households and migrants.
Juna Miluka, Gero Carletto, Benjamin Davis and Alberto Zezza This paper investigates the impact of international migration on technical efficiency, resource allocation and income from agricultural production of family farming in Albania. The results suggest that migration is used by rural households as a pathway out agriculture: migration is negatively associated with both labor and non-labor input allocation in agriculture, while no significant differences can be detected in terms of farm technical efficiency or agricultural income. Whether the rapid demographic changes in rural areas triggered by massive migration, possibly combined with propitious land and rural development policies, will ultimately produce the conditions for a more viable, high-return agriculture attracting larger investments remains to be seen.
