Abstract: Although it is commonly believed that aggregate economic growth must be associated with public infrastructure stocks, the possible infrastructure needs and effects are different from industry to industry. The agriculture sector is typical. Various infrastructures would affect agriculture growth differently depending on the type of commodity. This paper finds that a general transport network is essential to promote coffee and cocoa production, perhaps along with irrigation facilities, depending on local rainfall. Conversely, along with the transport network, the dairy industry necessitates rural water supply services as well. In some African countries, a 1 percent improvement in these key aspects of infrastructure could raise GDP by about 0.1-0.4 percent, and by possibly by several percent in some cases.

Infrastructure and Poverty in Sub-Saharan Africa analyzes the extent to which, how, and how fast the infrastructure needs of the poor have been met in Sub-Saharan Africa. Estache and Wodon explore the extent to which some key policies have hurt or helped progress in trying to speed the expansions of coverage so clearly needed in the region. They focus on electricity, water, sanitation, and other services at the core of the day-to-day needs of the population, examining the extent to which reforms of the last 15-20 years have managed to reduce the infrastructure gap. They anchor their analysis on the evidence available about the macroeconomic importance of infrastructure for the region, the policies that have been adopted to accelerate coverage, and a detailed assessment of the poverty dimensions of infrastructure.

This book addresses the prospects and challenges concerning both soft and hard infrastructure development in Asia and provides a framework for achieving Asian connectivity through regional infrastructure cooperation towards a seamless Asia. Key topics included are: ' demand estimates of national and regional infrastructure in transport, electricity, information and communication technology, and water and sanitation; ' empirical results on the costs and benefits of regional infrastructure for economies and households; ' the impact of infrastructure development on the environment and climate; ' sources and instruments of infrastructure financing; ' best practices and lessons learned from the experiences of the Asian region and other regions; and ' experiences of public_private partnership projects. This insightful book will serve as a definitive knowledge product for policymakers, academics, private sector experts and infrastructure practitioners interested in the regional and national infrastructure demand, investment and benefits in the region. Concerned officials from private and public sectors, and other experts involved in environmental and natural resources studies will also find this compendium invaluable.

This paper provides an overview of the major current debates on infrastructure policy. It reviews the evidence on the macroeconomic significance of the sector in terms of growth and poverty alleviation. It also discusses the major institutional debates, including the relative comparative advantage of the public and the private sector in the various stages of infrastructure service delivery as well as the main options for changes in the role of government (i.e. regulation and decentralization).

This pocket-sized reference on key environmental data for over 200 countries includes key indicators on agriculture, forestry, biodiversity, energy, emission and pollution, and water and sanitation. The volume helps establish a sound base of information to help set priorities and measure progress toward environmental sustainability goals.

This study examines major challenges and issues associated with developing regional infrastructure through the fostering of regional cooperation in Asia, and provides a framework for pan-Asian infrastructure cooperation. The study's long-term vision is the creation of a seamless Asia (an integrated region connected by world-class, environmentally friendly infrastructure) in terms of both "hard" (physical) and "soft" (facilitating) infrastructure. The soft part supports the development and operation of the hard component. Findings indicate that the benefits of upgrading and extending Asia's infrastructure networks are substantial, and that all countries in the region would benefit. A logistics network is only as good as its weakest link; each country in a regional supply chain gains from infrastructure improvements made in others. Improving connectivity in the region would bring Asia large welfare gains through increased market access, reduced trade costs, and more efficient energy production and use. According to the study, to achieve this Asia needs to invest approximately $8 trillion in overall national infrastructure between 2010 and 2020. In addition, Asia needs to spend approximately $290 billion on specific regional infrastructure projects in transport and energy that are already in the pipeline
