to establish impact, attributing observed changes in welfare to the intervention, while identifying key factors of success. Impact evaluations are aimed at providing feedback to help improve the design of programs and policies. They also provide greater accountability and a tool for dynamic learning, allowing policymakers to improve ongoing programs and ultimately better allocate funds across programs. Such a causal analysis is essential for understanding the relative role of alternative interventions in reducing poverty. The papers in this section again adopt a variety of techniques. The rst two impact evaluation studies employ propensity score matching to establish, ex-post, a valid control group to assess the impact on child schooling outcomes among b- e ciaries of various interventions in Kenya and Ethiopia. The third chapter c- ries out an ex-ante evaluation of alternative cash transfer programs on child school attendance in Uruguay. The nal paper further carries out in-depth macro-modeling and micro-regression analysis to simulate the impacts of the food crisis and various policy responses, including food subsidies and cash transfers, on various dimensions of child poverty in Mali. Though using different approaches, the studies are gen- ally in agreement concerning the positive impact of the cash transfer program on child schooling and labor market outcomes. The studies from Kenya and Uruguay both nd that the schooling interventions are progressive.

This book examines the link between environmental conservation practices and agricultural productivity in a fragile ecological environment in Kajiado district, Kenya. The work was carried out against the background of growing concern that declining agricultural productivity and increasing poverty are a cause as well as a consequence of environmental degradation. The work sought to explore mechanisms for escaping from a poverty trap where poverty leads to increased resource degradation, which in turn leads to low productivity and to more poverty. Panel data is used to examine the nexus between environmental capital, farm productivity and profitability for the period. The book illustrates that environmental conservation practices reduce poverty through increased agricultural production. Provision of incentives for environmental conservation is the first step towards poverty reduction in the district. Other important policy implications include making labour markets more competitive, educating producers on the benefits of environmental conservation and about the need to conserve biomass.
