This paper is a report on one of three related case studies in Latin America and shows the progress in the city of Chetumal, and the larger state of which it is the capital (Quintana Roo), in disaster response, especially with regard to cyclones. It also shows the progress in land use and ecological planning through the development of certain tools, which have changed the approach from one of prohibiting action to suggesting alternatives. Rather than stopping development, the focus has been on taking full account of its impacts and trying to make development compatible with environmental protection. There has also been progress in ecosystem conservation and water management, coordinated between different levels of government and different stakeholders. While much of this has taken place within the formal framework set by government, participatory processes have increased civil society awareness and commitment to environmental issues, and its capacity to participate and take a position, especially during the planning stages.
