How Do Climate Adaptation Policies Affect Deforestation? Evidence from a Large-Scale Water Policy

Brasil - Publicado el 2025-12-12

This paper examines the effects of a climate adaptation policy on production and environmental outcomes in the context of Brazil’s semiarid region, the country’s poorest and most drought prone region. The large-scale, low-cost water policy builds rainwater reservoirs designed to boost production and strengthen rural producers’ resilience. Using a difference-in-differences approach and linking property-level administrative data to high resolution satellite data, we find that cistern construction real locates land toward higher-productivity uses. Results indicate an increase in cropland area by 7.6% and higher-quality pasture area by 14.5%, while lower-quality pasture area decreases by 3.2%. Forest cover increases by 1.1%, consistent with a land saving effect driven by a reduction of lower-quality pasture. Effects hold across property sizes and are slightly larger in magnitude for small-sized properties. Our cost-benefit analysis reveals a positive aggregate return with each invested monetary unit generating 1.76 units of benefits, indicating that adaptation policies can also advance mitigation goals via forest preservation.

Water Security in Barbados and 11 countries of the Eastern Caribbean

Barbados, Caribe - Publicado el 2025-10-30

Caribbean countries are highly vulnerable to natural disasters. Extreme weather events are common, the region experienced three Category 5 hurricanes between 2017 and 2019. When a hurricane hits, it can wipe out the entire annual GDP of a small island and it is often the poorest who suffer the most. Major hurricanes, including Irma and Maria, in 2017, and Dorian in 2019 were stark reminders of this reality. This vulnerability includes challenges to water security, including water scarcity, water stress and drought, pollution, watershed degradation, saline intrusion, and flooding. Climate change is worsening the severity of these challenges, and response capacities are often curtailed by a lack of financial resources, poor coordination between institutions and less than optimal governance structures and procedures.

Economía azul para la salud de los océanos y el desarrollo sostenible

América Latina - Publicado el 2025-09-12

"Economía azul para la salud de los océanos y el desarrollo sostenible", es un informe de ImpactoCAF que describe la importancia del territorio marítimo y costero de América Latina y el Caribe para el desempeño de actividades clave en la economía regional, a la vez que describe los esfuerzos de CAF para protegerlo y asegurar la conservación de sus recursos en el largo plazo.

En específico se detalla la acción impulsada por CAF en diversas áreas de intervención, como la creación y gestión de áreas marinas protegidas, la prevención y erradicación de especies invasoras, el apoyo a sistemas de vigilancia para el monitoreo, detección y control de la pesca INDNR, la rehabilitación de corales, la gestión integral de sargazo, entre otras.

Estas acciones impactan potencialmente en la conservación de la biodiversidad, la resiliencia frente al cambio climático y el bienestar económico de las comunidades costeras.
