This report seizes the opportunity to learn from existing evidence by analyzing lessons derived from impact evaluations produced between 2000 and January 2009 to begin to discern what has been effective in agriculture. It is part of a broader effort being undertaken by the Independent Evaluation Group (IEG) of the World Bank to understand how impact evaluations can help improve performance and broadly disseminate those lessons.

The point of departure of this paper is that in the absence of effectively functioning asset markets the distribution of wealth matters for efficiency. Inefficient asset markets depress total factor productivity (TFP) in two ways: first, by not allowing efficient firms to grow to the size that they should achieve (this could include many great firms that are never started); and second, by allowing inefficient firms to survive by depressing the demand for factors (good firms are too small) and hence factor prices.

This paper evaluates the effect of the Rural Capacity Building Project, which aimed at promoting growth by strengthening the agricultural service systems in Ethiopia and by making them more responsive to smallholders' needs. The project intended to increase the outreach of agricultural extension services to help farmers become aware of and adopt economically viable and environmentally sustainable technologies and practices. The paper examines the impact of the Rural Capacity Building Project using panel data on 1,485 geographically dispersed households in project and control kebeles.

In the last two decades, across a range of countries high growth rates have reduced poverty but have been accompanied by rising inequality. This paper is motivated by this stylized fact, and by the strong distributional concerns that persist among populations and policy makers alike, despite the poverty reduction observed in official statistics where growth has been sufficiently high. This seeming disconnects frames the questions posed in this paper. Why the disconnect, and what to do about it?

Earnings from farming in many developing countries have been depressed by a pro-urban bias in own-country policies as well as by governments of richer countries favoring their farmers with import barriers and subsidies. Both sets of policies, which reduce national and global economic welfare and contribute to global inequality and poverty, have been undergoing reform since the 1980s.

This social assessment (SA) was conducted under the Fergana Valley Water Resources Management Project (FVWRMP), which is providing assistance to the Government of Tajikistan to address irrigation and drainage deficiencies in Eastern Sughd. The main SA objectives were to understand how prevailing structures of water provision, land reforms, and gender relations impact rural livelihoods; to analyze experiences in establishing inclusive Water Users Associations (WUAs); and to provide recommendations to FVWRMP with the aim of enhancing its programs.

In 1990, Australia and New Zealand were ranked around 25th and 37th in terms of Gross National Product (GNP) per capita, having been the highest-income countries in the world one hundred years earlier. Those countries relatively poor economic growth performance over that long period contrasts markedly with that of the past 15 years, when these two economies out-performed most other high-income countries. This difference in growth performance is due to major economic policy reforms during the past two to three decades, both at and behind the border.

This paper uses new data on agricultural policy interventions to examine the political economy of agricultural trade policies in Sub-Saharan Africa. Historically, African governments have discriminated against agricultural producers in general (relative to producers in non-agricultural sectors), and against producers of export agriculture in particular. While more moderate in recent years, these patterns of discrimination persist. They do so even though farmers comprise a political majority.

Bangladesh has made good progress in reducing poverty over the past decade despite the series of external shocks which have routinely affected the country. Poverty fell from 49 percent in 2000 to 40 percent in 2005, propelled by respectable economic growth and relatively stable inequality. These statistics are reflected in tangible improvements in poor people's lives, such as a sharp reduction in those living under flimsy straw roofs in rural areas.

Reforms in recent decades have sharply reduced the distortions affecting agriculture in developing countries, particularly by cuts to agricultural export taxes and by some reductions in government assistance to agriculture in high-income countries, but international trade in farm products continues to be far more distorted than trade in nonfarm goods. This paper summarizes a series of empirical studies that focus on the effects of the remaining distortions to world merchandise trade for poverty and inequality, especially in developing countries.

There is much in common between the agricultural sectors of the United States and Canada. This chapter begins with a brief background on the two sectors, then reviews their histories of farm policy developments before reporting new estimates of rates of assistance to their farmers and their consequences for taxpayers and consumers. This is followed by an explanation of the politics behind the evolution and gyrations in farm policies in the two countries, and some speculation on the prospect for reform.

This chapter begins with a brief summary of the long history of national distortions to agricultural markets. It then outlines the methodology used to generate annual indicators of the extent of government interventions in markets, details of which are provided in Anderson and appendix A.
