Central/South America

The guide serves as a primer for decision and policy makers, technical specialists, central, regional and local government officials, and concerned stakeholders in the community sector, civil society and non-governmental organizations, and the private sector. The Guide embodies the state-of-the art on integrated urban flood risk management. The Guide starts with a summary for policy makers which outlines and describes the key areas which policy makers need to be knowledgeable about to create policy directions and an integrated strategic approach for urban flood risk management.

In the Andes, runoff from glacierized basins is an important element of water budgets, assuring year-round flows for agriculture, potable water, power generation, and ecosystem integrity. Thus, changes induced by tropical glacier retreat constitute an early case of the need for adaptation and the type and size of associated economic and social impacts caused by climate change.

Global climate models predict a rise in extreme weather in the next century. To better understand future interactions among adaptation costs, socioeconomic development, and climate change in developing countries, observed losses of life from floods and droughts during 1960–2003 are modeled using three determinants: weather events, income per capita, and female education. The analysis reveals countries with high female education weathered extreme weather events better than countries with equivalent income and weather conditions.

The risk of losing income and productive means due to adverse weather can differ significantly among farmers sharing a productive landscape and is, of course, hard to estimate or even “guesstimate” empirically. Moreover, the costs associated with investments in adaptation to climate are likely to exhibit economies of scope. We explore the implications of these characteristics on Costa Rican coffee farmers’ decisions to adapt to climate change, using a framed field experiment.

This paper discusses the interplay between international trade, regional adaptation to climate change and financial transfers for funding adaptation. It combines insights from a theoretical model of North-to-South transfers with the findings of a calibrated dynamic multi-region multi-sector computable general equilibrium model that takes into account the impacts of climate change and the adaptation to it. Assessing the effects of adaptation funding indicates that funding of adaptation in developing regions can be Pareto-improving.

There is concern that climate change may greatly increase the costs of providing water infrastructure in rich countries, but the estimates available cannot be compared across countries. This paper develops and applies a top-down approach to estimate the costs of adapting to climate change on a consistent basis for different climate scenarios. The analysis separates (a) the costs of maintaining service standards for a baseline projection of demand, and (b) the costs of changes in water use and infrastructure as a consequence of changes in climate patterns.

This paper reviews the literature on the relationship between climate and the energy sector. In particular,we primarily discuss empirical papers published in peer-reviewed economics journals focusing on how climate affects energy expenditures and consumption. Climate will affect energy consumption by changing how consumers respond to short run weather shocks (the intensive margin) as well as how people will adapt in the long run (the extensivemargin).

The risk of losses of income and productive means due to adverse weather can differ significantly among farmers sharing a productive landscape, and is of course hard to estimate, or even “guesstimate” empirically. Moreover, the costs associated with investments in reduced vulnerability to climatic events are likely to exhibit economies of scope. We explore the implications of these characteristics on farmer's decisions to adapt to climate change using a framed field experiment applied to coffee farmers in Costa Rica.

Neither the costs nor the benefits of adaptation to climate change have been systematically studied so far. This paper discusses the extent to which the vast body of literature on climate change impacts can provide insights into the scope and likely cost of adaptation. The ways in which the impacts literature deals with adaptation can be grouped into four categories: no adaptation, arbitrary adaptation, observed adaptation (analogues), and modeled adaptation (optimization). All four cases are characterized by the simple assumptions made about the mechanisms of adaptation.

This paper reviews the empirical and theoretical literature on economic growth to examine how the four components of the climate change bill, namely mitigation, proactive (ex ante) adaptation, reactive (ex post) adaptation, and ultimate damages of climate change affect growth, especially in developing countries. The authors consider successively the Cass-Koopmans growth model and three major strands of the subsequent literature on growth: with multiple sectors, with rigidities, and with increasing returns.
