Extension services are a keystone of information diffusion in agriculture. This paper exploits a large randomized controlled trial to track diffusion of a new technique in the classic Training and Visit (T&V) extension model, relative to a more direct training model. In both control and treatment communities, contact farmers (CFs) serve as points-of-contacts between agents and other farmers. The intervention (Treatment) aims to address two pitfalls of the T&V model: i) infrequent extension agent visits, and ii) poor quality information.

In less than fifty years, Brazil evolved from a predominantly rural society and economy to a highly urbanized country in which 85 percent of its people now live in urban areas and more than 90 percent of the country’s GDP is generated in the cities. This rapid urbanization process was characterized by a lack of planning and an enduring framework of inequality, resulting in high degrees of concentrated poverty in the urban areas. Much of this urbanization has taken place in metropolitan regions (MRs).

Ulaanbaatar's (UB) population has swollen from half a million in 2001 to approximately 1.2 million in 2011, accounting for over 40 percent of the country's population. This trend is likely to continue as economic growth is increasingly concentrated in UB. With its growing population and concerns in rising inequality, the city is facing increasing pressure to maintain and expand service provision (especially infrastructure). The local tax on wages is expected to continue to provide substantial revenues to the UB government, which will assist the growing demand for services.

As part of a national experiment in 2008, Chengdu prefecture implemented ambitious property rights reforms, including complete registration of all land together with measures to ease transferability and eliminate migration restrictions. A triple difference approach using the Statistics Bureau’s regular household panel suggests that the reforms increased consumption and income, especially for less wealthy and less educated households, with estimated benefits well above the cost of implementation.

Cities emerge from the spatial concentration of people and economic activities. But spatial concentration is not enough; the economic viability of cities depends on people, ideas, and goods to move rapidly across the urban area. This constant movement within dense cities creates wealth but also various degrees of unpleasantness and misery that economists call negative externalities, such as congestion, pollution, and environmental degradation.

Cambodia emerged in the early 1990s from 30 years of conflict, the brutal Khmer Rouge era, and a decade of Vietnamese occupation, with one of the world’s lowest per-capita incomes, and with social indicators far behind those of neighboring Southeast Asian countries. Physical infrastructure had been largely destroyed. United Nations intervention led to a peace agreement in 1991, a new constitution, elections, and formation of a coalition government, although a reduced level of conflict and political instability continued until the late 1990s.

In the past 50 years, Indian agriculture has undergone a major transformation, from dependence on food aid to becoming a consistent net food exporter. The gradual reforms in the agricultural sector (following the broader macro-reforms of the early 1990s) spurred some unprecedented innovations and changes in the food sector driven by private investment. These impressive achievements must now be viewed in light of the policy and investment imperatives that lie ahead.

Cities exist, grow, and prosper because they take advantage of scale economies and specialization wrought by agglomeration. But output growth inevitably stresses transport infrastructure because production requires space and mobility. To prevent congestion from crowding out agglomeration benefits and to expand the supply of urban land, cities must invest in transport infrastructure. Yet balancing the growing demand for infrastructure with its supply is often difficult. In particular, many cities lack the funding to maintain and expand streets and urban highways.

This report responds to a request from the Government of Timor-Leste (GoTL) and Dr. Mari Alkatiri. The request was for World Bank assistance to collaborate on a range of studies relating to opportunities in the special economic zone, including community development, trade and competitiveness, and regional integration. The analysis builds on a situation analysis prepared by the Zona Especial de Economia Social de Mercado (ZEESM) authority in March 2014.

The purpose of this paper is to contribute to theunderstanding and discussion of how the costs andbenefits of natural resource development are sharedacross society. This paper presents how IFC, as both aninvestor and a development organization, determineswhether benefits and costs are shared reasonably, and how this assessment influences IFC’s decision to invest ina particular natural resource project. the goal of the paper is to promotea broad, constructive dialogue across stakeholders—governments, investors, civil society, and others—around benefit sharing.

This South African Agricultural Public Expenditure Review (AgPer) is one of a series of similar studies undertaken in several countries in Sub-Saharan Africa under the Comprehensive Africa Agriculture Development Program (CAADP) of the African Union’s (AU) New Partnership for Africa’s Development (NEPAD) which encourages governments and development partners (DPs) to target public expenditure on the agriculture sector as the most effective way of stimulating growth.

World Bank Group President, James Wolfensohn addressed the Board of Governors. In the past year the Bank launched a new initiative—the Comprehensive Development Framework (CDF). The aim was to bring the social and the structural aspects of development together with the macroeconomic and the financial so as to establish a much more balanced and effective approach. The Bank will work with the broad development community—the United Nations, the European Union, bilaterals, regional development banks, civil society, and the private sector—to build genuine partnerships.
