AbstractThe debate on the land–poverty nexus is inconclusive, with past research unable to identify the causal dynamics. We use a unique global panel dataset that links survey and census derived poverty data with measures of land ecosystems at the subnational level. Rainfall is used to overcome the endogeneity in the land–poverty relationship in an instrumental variable approach. This is the first global study using quasi-experimental methods to uncover the degree to which land improvements matter for poverty reduction. We draw three main conclusions. First, land improvements are important for poverty reduction in rural areas and particularly so for Sub-Saharan Africa. Second, land improvements are pro-poor: poorer areas see larger poverty alleviation effects due to improvements in land. Finally, irrigation plays a major role in breaking the link between bad weather and negative impacts on the poor through reduced vegetation growth and soil fertility.

Abstract The UN Population Division currently projects the population of Sub-Saharan Africa will reach 4 billion by the end of this century, unless we see a sharp decline in the region’s fertility rates. Although the region has embarked on its demographic transition, this process is occurring at a slower rate than in the rest of the developing world and seems to be stalling in several countries. The economic benefits that would follow from an acceleration of the fertility decline are now widely recognized but the SSA leadership is only slowly changing its attitude towards population issues. This paper’s discussion of SSA population growth focuses on fertility, and the identification of factors that may lead to fertility decline, with particular attention to the direct influence of public institutions. These are the public institutions dealing with family planning programs or those designed to prepare and implement population policies and/or monitor the demographic dividend. Reviewing the experience of these institutions in the SSA context allows us to suggest ways to strengthen them with the view of accelerating the fertility transition in the region, opening a demographic window of opportunity, and capturing a first demographic dividend.
