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.

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.

How to manage urban expansion in mega-metropolitan areas?

Philip E. Karp's picture

As the world becomes increasingly urbanized, the number of megacities is growing rapidly.

Today there are 37 cities worldwide with populations of greater than 10 million, and 84 with populations greater than five million. More than three quarters of these cities are in developing countries. Together with their surrounding metropolitan areas, these cities produce a sizable portion of the world’s wealth and attract a large share of global talent.

These megacities face a series of common challenges associated with managing urban expansion, density, and livability—in a manner that takes advantage of the benefits of productive agglomerations, while mitigating the disadvantages of such high degrees of congestion and urban density.

Moreover, like other metropolitan areas, megacities face challenges of effectively coordinated planning, infrastructure development, and service delivery across multiple jurisdictions. Indeed, the New Urban Agenda issued at the Habitat III conference in 2016 identified metropolitan planning and management as one of the most critical needs to ensure sustainable urbanization.
