Abstract
The São Paulo Macro Metropolis (SPMM) is one of the richest and most inequitable regions of the Global South and is already experiencing the impacts of severe climate events. This study analyzes climate risk assessments and policy responses for this territory as well as its vulnerabilities. The Index of Vulnerability to Natural Disasters related to Droughts in the Context of Climate Change (IVDNS—acronym in Portuguese) was used to identify and select the most vulnerable municipalities in the SPMM. Following vulnerability analysis, the municipalities were subjected to risk analysis in the context of existing Brazilian legislation. The results indicate that, despite having positive capacities to respond to climate change, the analyzed municipalities are far from advancing from the status quo or taking the actions that are necessary to face future challenges in a climate emergency scenario. The results indicate that, despite being the most vulnerable to droughts and natural disasters, the cities analyzed are not the most vulnerable in the São Paulo Macro Metropolis from a socio-economic point of view. On the contrary, these are regions that could have a strong institutional capacity to respond to present and future challenges.
Highlights
Analysis of the climatic risk assessments and policy responses for the São Paulo MacroMetropolis (SPMM) is necessary and urgent
The first and second procedures seek to identify those municipalities of the São Paulo Macro Metropolis (SPMM) that are considered most vulnerable, through the application of the Index of Vulnerability to Natural Disasters related to Droughts in the Context of Climate Change (IVDNS—acronym in Portuguese)
From the indicators extracted from IVDNS, 19 of the most vulnerable municipalities within the SPMM were selected for analysis (Figure 3)
Summary
Analysis of the climatic risk assessments and policy responses for the São Paulo Macro. 2015) indicate the need for a regional policy response to climate issues, their interdependencies, and vulnerabilities [1]. This regional approach complements current perspectives that are focused on either the national or city level. One apparent reason for this lack of regional focus is the non-availability of regional or local climate change scenarios. There is an absence of scenarios and technological innovations on the SPMM scale. There is an urgent need to conduct climate change risk and a policy response assessment for the region
