The Paris pledges and the energy-water-land nexus in Latin America: Exploring implications of greenhouse gas emission reductions.

In the 2015 Paris Agreement, nations worldwide pledged emissions reductions (Nationally Determined Contributions-NDCs) to avert the threat of climate change, and agreed to periodically review these pledges to strengthen their level of ambition. Previous studies have analyzed NDCs largely in terms of their implied contribution to limit global warming, their implications on the energy sector or on mitigation costs. Nevertheless, a gap in the literature exists regarding the understanding of implications of the NDCs on countries' Energy-Water-Land nexus resource systems. The present paper explores this angle within the regional context of Latin America by employing the Global Change Assessment Model, a state-of-the-art integrated assessment model capable of representing key system-wide interactions among nexus sectors and mitigation policies. By focusing on Brazil, Mexico, Argentina and Colombia, we stress potential implications on national-level water demands depending on countries' strategies to enforce energy-related emissions reductions and their interplays with the land sector. Despite the differential implications of the Paris pledges on each country, increased water demands for crop and biomass irrigation and for electricity generation stand out as potential trade-offs that may emerge under the NDC policy. Hence, this study underscores the need of considering a nexus resource planning framework (known as "Nexus Approach") in the forthcoming NDCs updating cycles as a mean to contribute toward sustainable development.

Estudio de caso de adaptación al cambio climático: impactos del cambio climático durante las sequías en la ciudad de Trujillo, Perú / Climate Change Adaptation Case Study: Climate Change Impacts during Droughts on the City of Trujillo, Peru

Los casos de estudios se basan en actividades en desarrollo del BID en la región de América Latina y que tienen por finalidad ofrecer información local y análisis que ayuden a los administradores de recursos hídricos locales en hacerle frente a los desafíos del cambio climático, así como también preparar directrices sobre la forma de integrar la adaptación al cambio climático en la implementación de proyectos financiados por el Banco y para identificar explícitamente el impacto de las medidas de adaptación.
