About 70% of the population of Latin American and Caribbean live in urban areas and that percentage is expected to rise. As urban centers grow, demand increases for social infrastructure such as health care, education and housing. Urban development should be guided by sustainable planning and management that promotes effective social infrastructure to meet demand, a multi-modal transportation system, and mixed-use development. Various approaches have been developed to construct or rehabilitate buildings in a sustainable manner, thus reducing costs, energy and water use, as well as the overall environmental footprint. Public and private partnerships can create sustainable and livable communities that protect historic, cultural, and environmental resources. Sustainable urban planning and project construction techniques can help reduce pollution and create a balance between natural and manmade systems.
