. According to United Nations (UN) estimates, four billion people – more than half of the world’s population – live in urban areas today.
In addition, rising global temperatures increase the risks of rising water levels, landslides, droughts, hurricanes, and other disasters. Without urgent action, these climate impacts could push an additional 100 million people into poverty by 2030, according to the World Bank.
The good news is that, armed with knowledge and creativity, urban centers are finding ways to tackle new and old problems alike, with fewer losses and greater recovery capacity – in other words, creating "resilience".
The Catalyzing Sustainable Urban Futures global conference held recently in São Paulo, Brazil, which was co-hosted by the São Paulo City Hall, the Sustainable Cities Program, and the World Bank’s Global Platform for Sustainable Cities (GPSC), with the support of the Global Environment Facility (GEF), looked closely at this topic of “resilience”.
Representatives from four continents examined three global issues, with sustainability and resilience as an ever-present backdrop. The first was climate change, a concern that mayors can no longer afford to sidestep.
The second issue was the need for more green spaces – think about public parks with trees, birds, bees, and other species. Today, around one million animal and plant species are threatened with extinction, eroding the foundation of our shared livelihood, society’s ability for adaptation, and nature’s capacity to store carbon.
Third, there was a constant discussion about solid waste management. Without it, rivers will overflow and the air will be polluted by harmful substances, among other problems. With it, millions of people, including those in the recycling industry, will be presented with new opportunities.
Mitigating and adapting to climate change
and much of it occurs near natural hazards, rivers, and coastal regions, in the form of informal and unplanned settlements. A lack of infrastructure and proper land use plans exacerbates the risks facing residents, especially in view of climate change. Thus, several cities are now devising their own mitigation and adaptation plans. São Paulo, for example, is set to launch its plan in June 2020.
Another Brazilian city, Recife, already has a plan in place, in preparation for the city's 500th anniversary celebration in 2037. One-third of the local population lives in hill areas susceptible to disasters; another third of the population resides at sea level, which means that flooding is a threat.
“With the participation of civil society and the general population, we have compiled a strategic plan based on a set of urban and environmental plans containing a series of initiatives to mitigate [disaster risks], increase resilience, and adapt to the consequences of the climate crisis," stated Mayor Geraldo Júlio at the conference.
Plans in developed countries are even more ambitious. Paris, France, has pledged to become a carbon-neutral city by 2050, enacting 500 measures in various industries, such as construction, transport, energy, and food. These measures include goals such as using only green energy (biomass, wind, and solar), banning diesel cars by 2024, and eliminating all cars running on petrol fuels by 2030.
