Irrigation projects have been the subject of much bad press coverage because of the sometimes very damaging environmental and social impacts associated with large-scale projects such as dams, declining aid to agriculture and falling rates of economic returns to irrigation since the heyday of the 1970s. Yet irrigation remains one of the most crucial inputs into farming and therefore a potentially important poverty reduction tool for the 21st century. We review some of the evidence surrounding trends in investments in irrigation and the reasons behind the decline. We also provide a framework for analysing the positive and negative impacts of irrigation on poverty, how these might differ by the type of irrigation technology and review some of the evidence of these impacts. We reach a number of conclusions about the conditions under which irrigation is most likely to have a positive impact on the poor, but we also report that the evidence is patchy, and usually not gathered in such a way as to allow easy conclusions to be drawn.

Measured by the Gini coefficient, income inequality in Brazil rose from 0.57 in 1981 to 0.63 in 1989, before falling back to 0.56 in 2004. This latest figure would lower Brazil's world inequality rank from 2nd (in 1989) to 10th (in 2004). Poverty incidence also followed an inverted U-curve over the last quarter century, rising from 0.30 in 1981 to 0.33 in 1993, before falling to 0.22 in 2004. Using standard decomposition techniques, this paper presents a preliminary investigation of the determinants of Brazil's distributional reversal over this period. The rise in inequality in the 1980s appears to have been driven by increases in the educational attainment of the population in a context of convex returns, and by high and accelerating inflation. While the secular decline in inequality, which began in 1993, is associated with declining inflation, it also appears to have been driven by four structural and policy changes which have so far not attracted sufficient attention in the literature, namely: sharp declines in the returns to education; pronounced rural-urban convergence; increases in social assistance transfers targeted to the poor; and a possible decline in racial inequality. Although poverty dynamics since the Real Plan of 1994 have been driven primarily by economic growth, the decline in inequality has also made a substantial contribution to poverty reduction.

This paper evaluates the impact of migrant remittances on human capital accumulation among youth. An augmented human capital model with two outcomes, education attendance and education attainment, is estimated using a large nationally representative household survey from Jordan. Empirical results show that migrant remittance receipt has a positive effect on education attendance. This finding is obtained while controlling for other socio‐economic determinants of schooling behavior and is robust to censorship and endogeneity bias. The results also indicate that the magnitude of the remittance impact on both education outcomes is larger for men compared with that of women.

This paper implements and adapts the conceptual framework developed by Winters (2002) that identifies the transmission mechanisms between trade policy reform and household welfare outcomes. We make use of household panel data from Vietnam collected in two years, 1992-93 and 1997-98 that span the very earliest years of the reform period and its immediate after effects. Poverty dynamics are modeled using changes in consumption expenditure and poverty transition models. The trade effect is captured by a set of variables that are most likely to have an impact on rural poverty, namely prices of staples and employment in the export sector. We show that trade liberalization has a material and positive effect on rural household welfare and this trade effect is largely transmitted to the poor through the labor market channel.
