The El Nino Southern Oscillation (ENSO) weather event of 2015/16 caused severe drought conditions in northern and central Ethiopia affecting the welfare of millions of farmers in late 2015 and early 2016. Using nationally representative panel data collected in 2012 and 2016 and recent advances in the difference-indifferences literature, this paper explores the effects of the 2015/16 drought and the potential role of irrigation in reducing the adverse effects of the drought. We find that the drought caused, on average, a 37 percent reduction in net annual crop income, an 8 percent decline in area cultivated, a 3 percent decline in household dietary diversity score, and a 10 percent decline in the share of harvest sold for rainfed farmers. On the other hand, irrigating farmers affected by the drought managed to increase their daily expenditures by 72 percent of their average daily food expenditure in the pre-drought period, and maintained their net crop income, size of cultivated land, household dietary diversity, and share of harvest sold to the market. Overall, while rainfed agricultural producers suffered sharp declines in welfare, those farmers with access to irrigation maintained their economic status. The results suggest that irrigation protected farmers from the adverse effects of the 2015/16 ENSO event and given increasing climate variability in Ethiopia, the government should intensify its investment and support to irrigation development in the country.

This book provides an accessible, undergraduate-level introduction to computable general equilibrium (CGE) models, a class of model that has come to play an important role in government policy decisions. The book uses a graphical approach to explain the economic theory that underlies a CGE model, and provides results from simple, small-scale CGE models to illustrate the links between theory and model outcomes. The book includes eleven guided, hands-on exercises that introduce modeling techniques that are applied to real-world economic problems. Students will learn how to integrate their separate fields of economic study into a comprehensive, general equilibrium perspective as they develop their skills as producers or consumers of CGE-based analysis.

In recent years, a greater level of integration of the world economy and an opening of national markets to trade has impacted virtually all areas of society. The process of globalization has the potential to generate long-term benefits for developing countries, including enhanced technology and knowledge transfers and new fina- ing options supporting agricultural and economic development. However, risks of political and economic instability, increased inequality, and losses in agricultural income and production for countries that subsidize their agricultural and other e- nomic sectors threaten to offset potential benefits. Globalization can also have a profound impact on the water sector – in terms of allocation and use of water – and thus on food security as well. Other global change processes, particularly climate change, are also likely to have far-reaching impacts on water and food security, and societies around the world. To discuss these issues in-depth, the International Food Policy Research Institute, the Third World Centre for Water Management, Mexico, and the Tropical Agricultural Research and Higher Education Center (CATIE), Costa Rica, held a three-day International Conference on “Globalization and Trade: Implications for Water and Food Security,” at CATIE’s Turrialba, Costa Rica, headquarters under the auspices of the CGIAR Challenge Program on Water and Food in 2005. The workshop set out to identify the major risks and emerging issues facing developing countries related to global economic and environmental change impacts on water and food security.

Ending poverty and stabilizing climate change will be two unprecedented global achievements and two major steps toward sustainable development. But the two objectives cannot be considered in isolation: they need to be jointly tackled through an integrated strategy. This report brings together those two objectives and explores how they can more easily be achieved if considered together. It examines the potential impact of climate change and climate policies on poverty reduction. It also provides guidance on how to create a “win-win†? situation so that climate change policies contribute to poverty reduction and poverty-reduction policies contribute to climate change mitigation and resilience building. The key finding of the report is that climate change represents a significant obstacle to the sustained eradication of poverty, but future impacts on poverty are determined by policy choices: rapid, inclusive, and climate-informed development can prevent most short-term impacts whereas immediate pro-poor, emissions-reduction policies can drastically limit long-term ones.

The performance of the International Food Policy Research Institute’s (IFPRI’s) research program that focuses on water resource issues is reviewed for the period 1994–2010 around the three themes that constitute the program: global modeling, river basin modeling, and institutions. The IFPRI water team has been involved in leading-edge research in a number of dimensions: it has focused on analysis at varying geographic scales; the work has been truly interdisciplinary by engaging economics with biophysical science and other social sciences; and research outputs have been innovative in advancing institutional analysis and water pricing and in policy measures addressing the complexities of water supply management. In the research tasks, IFPRI’s water team actively collaborated with a wide range of researchers from within the CGIAR network, national research institutes, and universities. Within the team, a largely stable group of leaders has been responsible for the professional development of a substantial cohort of junior staff who have moved onto successful careers elsewhere. The output of the program has been prolific and prominent in academic, policy, and development communities. The approach taken is to review selected publications from the themes; assess the quality of the journals in which papers have been published; and evaluate the performance, on average, of researchers in the program. In addition, surveys of stakeholders were carried out, and three specific projects were subjected to detailed review. The assessment demonstrated the high regard in which the program research outputs and researchers are held. The IFPRI water team has been remarkably productive throughout the 16 years considered, working on issues that are of high relevance to policy and producing work that has largely been cutting edge. However, impacts generated by individual projects were not consistently or readily identifiable. To maximize the benefits of this performance and to overcome challenges associated with securing more outcomes, this report recommends that a more coordinated approach be taken to develop the research project portfolio. This would involve better targeting of projects to policy objectives through a more systematic review of research demand forces and improved integration of research work with policy development processes. The latter in particular requires the development of a sense of research project “ownership” within the policy circles the research is designed to influence. More effort in the development of in-country research partnerships can aid this process as local researchers can act as “champions” within local policy circles. Where government agencies have a research function, their integration into the partnerships is recommended. Avoidance of completing research projects in a “policy vacuum” is critical but requires both advanced planning of each research project as well as constant adaptation of the work plan to (often rapidly) evolving policy contexts. To achieve project impacts beyond the immediacy of the specific case study context, a more targeted and coordinated publication strategy should be developed in light of changing publication technology. Project webpages within the IFPRI website, with readily downloadable reports, are useful during the implementation of each project and more formal papers should be targeted for publication in high-impact factor technical journals with parallel papers prepared for more policy-oriented journals that have high circulations.

This book presents a comprehensive overview of climate variability and change in Africa, and includes impact assessments and case studies from integration frameworks, with a particular focus on climate, agriculture and water resources. Richly illustrated, the book highlights case studies from western, eastern and southern African region, and explores related development policies. Climate change adaptation research, prediction, and reanalysis are also addressed
