Climate Change and Extreme Weather Events in Latin America: An Exposure Index

AUTHOR(s): Garlati, Adrian
PUBLISHED: January 2013
RELATED TOPICS: Microeconomics


Climate change is changing the frequency and intensity of Extreme Weather Events (EWEs), particularly in poor developing countries, and the international community is increasingly suggesting the design of adaptation funds to resolve this situation. Measures of vulnerability and exposure to EWEs are a critical instrument in guaranteeing a transparent, efficient and equitable allocation process in these funds. Latin American countries, which contribute little to climate change but are hard-hit by EWEs, urgently need new indicators to back up their claims for financial and technical assistance. Using DesInventar data, the paper develops an innovative Disaster Exposure Index (DEI) that encompasses many disasters’ impacts. DEI calculations indicate an unexpected scenario where some regions usually considered resilient are found to be exposed. The results call for further development of regional indicators to facilitate the international, national and sub- national allocation of adaptation funds.

    This paper presents a recursive, dynamic CGBM to evaluate the impact of climate change on six six Latin American and Caribbean economies (Argentina, Brazil, Chile, El Salvador, Jamaica and Peru). The medium-sized model considers the relative prices mechanism and structural economic changes, as well as the impact of climate change on revenue levels and policies. Policies and conditional regulations ... (View publication)

    This paper surveys climate change funds related to Latin American and Caribbean countries and attempts to derive some implications through performance analyses of these funds. These analyses show that the following matters should be addressed: increases in the IDB’s participation as an agent in the projects for the region, enlargement of the scale of co-financing in the IDB-brokered cases as well ...

    The general objective of this study is to review the international literature and best practices to develop a methodological framework capable of quantifying the increase in investments necessary for a traditional standard of living in a world subject to climate change. This methodology is then applied to two case studies: Bolivia and Chile. In particular, the document addresses the economics of a ... (View publication)
