The papers significant biodiversity and valuable crops, and seek to bring to a broader public – decision makers, also harbors the world’s greatest carbon sink in development practitioners, academics and other the Amazon. At the same time, however, the region partners - lessons learned from World Bank- registers the highest rates of urbanization in the financed projects, technical assistance and other developing world with pollution, overuse of its water knowledge activities jointly undertaken with our and natural resources and detrimental impacts on partners. The series addresses issues relevant to the the health of people, especially the poor, and the region’s environmental sustainability agenda from environment. water resources management to environmental health, natural resource management, biodiversity Over the past twenty years, the LAC region has conservation, environmental policy, pollution made impressive gains in tackling these issues. management, environmental institutions and It leads the developing world in biodiversity governance, ecosystem services, environmental conservation and natural resource management financing, irrigation and climate change and their and is at the forefront in reducing urban pollution. linkages to development and growth. The World Bank has often been the partner of choice for those countries in the region that have In this particular case, we present to you the case had the initiative to pioneer innovative policies for of climate change adaptation in Campeche, one environmental protection and natural resource of Mexico’s coastal states, with high vulnerability management, strengthen institutions responsible to current and future climate impacts. The paper for environmental management, enhance highlights the concrete results for adaptation environmental sustainability, and introduce new planning that can be achieved by using a approaches to water resources management. Such combination of approaches, notably strategic initiatives include fuel and air quality standards environmental assessment, associated with the in Peru, carbon emission reduction in Mexico, cutting-edge real options theory approach, and payment for ecosystem services in Costa Rica, most importantly, a highly participatory process for participatory and integrated water resources developing and digesting the information. management in Brazil, and new approaches to We hope that this paper, just as the entire series, irrigation management in Mexico. will make a contribution to knowledge sharing In this context, it is our pleasure to introduce the within the LAC Region and globally.
