​Chongqing, the largest municipality in China, is investing in sustainable urban growth.

As China transitions from pursuing high-speed growth at any cost to a growth model that focuses on sustainability, inclusivity, and efficiency, cities like Chongqing are a critical part of this new urbanization strategy.

Cyclone Idai: Building climate and disaster resilience in Mozambique and beyond

Cyclone Idai is one of the most devastating storms to ever hit Africa, causing catastrophic damage in Mozambique, Malawi, and Zimbabwe.
 
Starting off in early March 2019 as a tropical depression, the storm rapidly evolved into a cyclone, affecting over 2 million people and killing close to 1,000 in the three countries affected. The port city of Beira, Mozambique – the hardest hit – is struggling to reemerge from the rubble.

#BuildBetterBefore to save lives and strengthen economies

For those of us who have family and friends living in earthquake and hurricane prone areas, the 1.3 million people that have died in disasters in the last 25 years are more than a staggering statistic. It’s personal.

In this video, Luis Triveno (@luis_triveno), Urban Specialist, sits down with Ede Ijjasz-Vasquez (@Ede_WBG), Senior Director, to discuss what the World Bank is doing to make homes safer – before it’s too late.

How can we use analytical approaches to generate urban climate investments in Africa?

As the world rushes to reduce the negative impacts of climate change, ambitious sub-national actors are rising to the fore. The recent One Planet Summit exemplifies this trend. Earlier this month, urban leaders joined CEOs, financial institutions, researchers, Heads of State, and more in the adoption of the Africa Pledge, calling for immediate voluntary actions and a specific commitment to invest in sustainable infrastructure across the continent. After all, the infrastructure investments we make today set the agenda for how cities will grow in the future.

For example, Sub-Saharan Africa is largely rural, but is also the region with the fastest urbanization rates. Currently, almost 40 percent of the people live in cities in Sub-Saharan Africa, but this is expected to grow to 60 percent or more by 2050. So while urbanization provides economic and social opportunity, it can overburden traditional municipal resource and service delivery approaches.

Changing impact of weather and climate services in response to changing climate

Have you ever wondered what your national meteorological agency actually does? I suppose it wouldn’t be inaccurate to say that they can help you decide how to dress, whether or not to carry an umbrella, or water the garden. But their purpose is so much bigger than that.

National meteorological and hydrological services (NMHSs) are responsible for helping people understand, predict and warn of weather- and water-related hazards such as storms, floods, and hurricanes.

India: How to help communities break the vicious "disaster-poverty" cycle

Ede Ijjasz-Vasquez's picture
 

Natural disasters push the near poor to below the poverty line & contribute to more persistent and severe poverty, creating poverty traps. Impacts on their livelihood pushes them further down the poverty line and as they own few assets it is very difficult for them to break this cycle.
Poor are caught up in and disaster-poverty vicious circle- are more likely to reside in hazardous locations and in substandard housing exposing them more to disasters. Poor households in disasters use harmful coping strategies, such as reducing expenditures on food, health, & education or increasing incomes by sending children to work.

What if we could use nature to prevent disasters?

Heavy rain and severe flooding brought the city of Colombo, Sri Lanka, to its knees. In China’s Yangtze River Basin, rivers spilled their banks, inundating towns and villages. In Mobile Bay, Alabama, strong ocean waves carried away valuable coastline.

In each of these locations, disasters caused by natural hazards seemed beyond human control. But instead of focusing only on building more drains, seawalls and dams, these governments turned to nature for protection from the disasters. Several years later, the urban wetlands, oyster reefs and flood plains they helped establish are now keeping their citizens safe while nourishing the local economies.

What a Waste 2.0: sharing lessons on solid waste management

By 2050, waste generation is projected to increase by 70 percent and drastically outpace population growth by more than double. Managing all that waste is becoming an important agenda for many developing countries.

The solid waste management sector offers opportunities for private entrepreneurship, resource conservation, and inclusiveness for marginalized populations; however, it also presents significant challenges in terms of technical, financial, and institutional capacities.

When sector-enabling conditions are not in place, waste is mismanaged, contaminating water bodies, clogging drains, causing flooding, and increasing diseases, all of which have significant environmental and economic cost for governments and societies.

What is “Plan V”?

Imagine a place where you've lived for decades. Not just you, but your parents’ parents, too. When they lived there, the place wasn't that big. There were just a few dozen families. Today the place is home to hundreds of – or maybe even a thousand – families.
 
This is a highly fertile, verdant place… You're at the foot of a volcano. 

The rise of local mapping communities

There is a unique space where you can encounter everyone from developers of self-driving cars in Silicon Valley to city planners in Niamey to humanitarian workers in Kathmandu Valley: the global OpenStreetMap (OSM) community. It comprises a geographically and experientially diverse network of people who contribute to OSM, a free and editable map of the world that is often called the “Wikipedia of maps.”  

What is perhaps most special about this community is its level playing field. Anyone passionate about collaborative mapping can have a voice from anywhere in the world. In the past few years, there has been a meteoric rise of locally organized mapping communities in developing countries working to improve the map in service of sustainable development activities.

The next opportunity to see the OSM community in action will be the November 14th mapathon hosted by the Global Facility for Disaster Reduction and Recovery (GFDRR)’s Open Data for Resilience Initiative (OpenDRI). Mapathons bring together volunteers to improve the maps of some of the world’s most vulnerable areas, not only easing the way for emergency responders when disaster strikes, but also helping cities and communities plan and build more resiliently for the future.
