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).

"Estache reviews the recent economic research on emerging issues for infrastructure policies affecting poor people in developing countries. His main purpose is to identify some of the challenges the international community, and donors in particular, are likely to have to address over the next few years. He addresses six main issues: (1) the necessity of infrastructure in achieving the Millennium Development Goals; (2) the various dimensions of financing challenges for infrastructure; (3) the debate on the relative importance of urban and rural infrastructure needs; (4) the debate on the effectiveness of infrastructure decentralization; (5) what works and what does not when trying to target the needs of the poor, with an emphasis on affordability and regulation challenges; and (6) the importance of governance and corruption in the sector. The author concludes by showing how the challenges identified define a relatively well integrated agenda for both researchers and the international infrastructure community. This paper,a product of the Office of the Vice President, Infrastructure Network,is part of a larger effort in the network to stimulate more analytical assessments of emerging issues in the sector"--World Bank web site.

Our understandings of the landscapes around us are constantly changing. How we interact with, manage and value these spaces is important, as it helps us to ensure we live in attractive, functional and sustainable places. Green Infrastructure planning is the current ‘go-to’ approach in landscape planning that incorporates human-environmental interactions, understandings of ecology and how socio-cultural factors influence our use of parks, gardens and waterways. This book explores several interpretations of Green Infrastructure bringing together case studies of policy, practice, ecological change and community understandings of landscape. Focusing on how planning policy shapes our interactions with the landscape, as individuals and communities, the book discusses what works and what needs to be improved. It examines how environmental management can promote more sustainable approaches to landscape protection ensuring that water resources and ecological communities are not harmed by development. It also asks what the economic and community values of Green Infrastructure are to illustrate how different social, ecological and political factors influence how our landscapes are managed. The central message of the book focusses on the promotion of multi-functional nature within urban landscapes that helps people, the economy and the environment to meet the challenges of population, infrastructure and economic change. The chapters in this book were origianally published as a special issue in Landscape Research.

In this comparison of infrastructure across countries and sectors, leading international academics and practitioners consider the latest approaches to infrastructure policy, implementation, and finance. The book presents evidence-based solutions and policy considerations, essential concepts and economic theories, and a current overview.

Electricity, natural gas, telecommunications, railways, and water supply, are often vertically and horizontally integrated state monopolies. This results in weak services, especially in developing and transition economies, and for poor people. Common problems include low productivity, high costs, bad quality, insufficient revenue, and investment shortfalls. Many countries over the past two decades have restructured, privatized and regulated their infrastructure. This report identifies the challenges involved in this massive policy redirection. It also assesses the outcomes of these changes, as well as their distributional consequences for poor households and other disadvantaged groups. It recommends directions for future reforms and research to improve infrastructure performance, identifying pricing policies that strike a balance between economic efficiency and social equity, suggesting rules governing access to bottleneck infrastructure facilities, and proposing ways to increase poor people's access to these crucial services.

This paper investigates the emerging global landscape for public-private co-investments in infrastructure. The creation of the Asian Infrastructure Investment Bank and other so-called “infrastructure investment platforms” are an attempt to tap into the pool of both public and private long-term savings in order to channel the latter into much needed infrastructure projects. This paper puts these new initiatives into perspective by critically reviewing the literature and experience with public private partnerships in infrastructure. It concludes by identifying the main challenges policy makers and other actors will need to confront going forward and to turn infrastructure into an asset class of its own.
