Most cities in the state of São Paulo have poor adaptability to climate change

Publicado em 09 junho 2021

Most cities in the state of São Paulo (Brazil) are less able to adapt to climate change, for example, in their ability to develop public policies that promote reforms in housing and transportation systems to explain the effects of climate change. There is a possibility.

This is the main conclusion of a study conducted by researchers at the University of Sao Paulo (USP) in collaboration with the University of Campinas (UNICAMP), the Federal University of Itajuba (UNIFEI) in Brazil, and colleagues at the University of Michigan. USA.

Researchers related to FAPESP-sponsored projects participated in the study.Results will be published in magazines Climate change..

The key findings were presented at the 9th Brazil-Germany Dialogue on Science, Research and Innovation on May 19th, entitled “Urban and Climate, Multi-Level Governance Challenges”.

Organized by FAPESP in collaboration with the German Center for Scientific Innovation (DWIH) in São Paulo, the event took place online May 17-20.

“It turns out that most cities in the state of São Paulo still have a lot of difficulty in coordinating. Public policy Can lead to adaptation Climate change“The last author of this study, Gabriela Marques Di Giulio, a professor at the University of São Paulo School of Public Health (FSP-USP), said.

To help cities assess their ability to cope with a crisis Impact of climate change Researchers have found that public policy and legislation or regulation in supporting climate change-related urban intervention in several areas, such as housing, by implementing policies that combine sustainability and adaptation in the short and long term. We have developed the Urban Adaptation Index (UAI), which measures effectiveness. , Mobility, agriculture, environment.

“UAI indicators can be based on public data such as the census conducted by IBGE. [Brazil’s national statistics bureau]The index is easily accessible and can be dynamically updated to reflect the changes that occur in the city, “said Dijurio.

Researchers used this index to evaluate 645 municipalities in the state of São Paulo. The results showed that more than half of the evaluated 5 dimensions had a low score.

Cities in metropolitan areas, where more than 50% of the state’s population lives, received the highest scores. “UAI helps cities strengthen their ability to adapt and spark more knowledgeable debates about how best to prepare for climate change,” said Di Julio.

The role of the city

Cities need to establish strategies to reduce. Greenhouse gas emissions, Professor Sabine Schlacke of the University of Münster (WWU), Germany, said, contributing to global efforts to achieve climate neutrality and mitigate the effects of climate change.

Since cities are part of the nation-state, they do not have the foreign policy authority or ability to act on the basis of international policy. climate Changes to the mitigation agenda are limited, but networks like the C40 allow you to organize collaboration with other cities. “For example, cities are not dealt with directly by the Paris Agreement. Nevertheless, cities can be involved in the contribution of national decisions that member states must submit, namely the development of the NDC,” Schracke said. Mr. says.

According to Cathrin Zengerling, a professor at the University of Freiburg, we are approaching the greenhouse gas emission targets needed to keep global average temperature rise below 2 ° C and 1.5 ° C higher than before the Industrial Revolution. There are few cities in the world, and the level set by the Paris Agreement.

One is Sao Paulo. “One of the reasons São Paulo is doing so well in this regard is that most of its electricity comes from hydropower,” Zengerling said.

She added that the cities that emit the most greenhouse gases are Denver in the United States, Chicago, Los Angeles, and Shanghai and Beijing in China.
