Green infrastructure is being recognized as one of the main strategies for climate emergency mitigation and adaptation in urban contexts. However, there are still very few initiatives in Latin America. This paper explores the Chilean case, in particular the "Stgo+ Green Infrastructure" project, to understand how the climate emergency has been included in green infrastructure planning and the level of priority it has among various types of stakeholders. The research was conducted through a review of planning documents and a participatory methodology, involving institutional, academic, and civil society stakeholders. Chilean urban regulations and territorial planning instruments do not offer much opportunity for the development of green infrastructure systems to face the climate emergency, but there are several indicative instruments that contribute in that sense. On the other hand, there is growing recognition by stakeholders of the importance of green infrastructure, but the climate emergency is an aspect that is still given low priority. The low priority that actors attribute to the climate emergency represents a significant barrier for the incorporation of these issues in public plans and policies. [ABSTRACT FROM AUTHOR]

Climate change, one of the main global risks humankind is currently facing, became a relevant issue on the international agenda in the last few decades. The United Nations Framework Convention on Climate Change (UNFCCC), adopted in 1992, includes both mitigation and adaptation strategies; however, though both are considered equally important, adaptation has been historically relegated to a secondary role within the Convention. The paper first presents an overview of the trajectory of adaptation as a UNFCCC guideline, discusses its institutional evolution and the Convention’s financing mechanisms, and, finally, explores the relations between adaptation and development. The conclusions point to the insufficiency of the Convention with respect to the implementation of measures for adaptation to climate change, but highlight its relevant role as a scenario for debate, as a source of funding, and as a promoter of both national and subnational actions, especially in developing countries.

The existence of contrasting definitions of vulnerability to climate change poses a crucial challenge for the relationship between science and public policy in the context of adaptation to climate change. After reviewing the mainstream conceptualization of vulnerability to climate change, the article criticizes the use of the risk-hazard approach as a conceptual basis for measuring that vulnerability. Using concrete examples, the article illustrates how the resulting concept of vulnerability varies profoundly with respect to the type of knowledge generated and the epistemological approach depending on whether the concept of inherent vulnerability or that of outcome vulnerability is used. The paper concludes that the use of one or the other leads to public policies that are radically different in scope. [ABSTRACT FROM AUTHOR]
