There is a myth that cooling technology is just for those who live in hot and humid climates. Let me break this illusion. How else do you think we would keep the food fresh and safe to eat? Or create and preserve medicines for people to shield their lives? Even the Internet relies on cooling technology to keep servers in massive data centers from overheating.
When our team started working in Freetown one year ago, we found very limited data on how people move or what are the public transport options to access jobs and services from different neighborhoods. How do you plan your public transport system when you do not have data? And what if you are also constrained by a highly vulnerable environment to natural disasters and poverty? Keep reading: Disruptive thinking has the answer.
Freetown, Sierra Leone’s capital city, is a vibrant city with an increasing population and a growing economy—and probably the best beaches in the region. It is a densely populated, congested city situated on a hilly peninsula surrounded by the Atlantic Ocean, the estuary of the Sierra Leone River and mountains, with very little flat space. The city creates 30% of the country’s GDP, which evidences the importance for the national economy. Although Freetown is the main employment center in Sierra Leone, the access to jobs and services in the city is heavily impaired by inadequate transport services and infrastructure and a chronic congestion.

Groundwater is fast disappearing in the Middle East and North Africa region. Under a business-as-usual approach to the use of these scarce resources, it is estimated that they will be gone in about 30 years. This will have a devasting impact on the communities and livelihoods that rely on this water. Agricultural production would drop by as much as 60% in some countries.
Machine learning algorithms are excellent at answering “yes” or “no” questions. For example, they can scan huge datasets and correctly tell us: Does this credit card transaction look fraudulent? Is there a cat in this photo?
But it’s not only the simple questions – they can also tackle nuanced and complex questions.
Today, machine learning algorithms can detect over 100 types of cancerous tumors more reliably than a trained human eye. Given this impressive accuracy, we started to wonder: what could machine learning tell us about where people live? In cities that are expanding at breathtaking rates and are at risk from natural disasters, could it warn us that a family’s wall might collapse during an earthquake or rooftop blow away during a hurricane?
Achieving sustainable development depends on incremental investments in six priority transformations: building human capacities (health, education, new job skills); decarbonising energy; promoting sustainable agriculture and biodiversity; building smarter cities; implementing the circular economy; and harnessing the digital revolution. As such, sustainable development and the 17 Sustainable Development Goals (SDGs) in particular pose a financing challenge. There are three distinct financing conundrums to solve: financing complex infrastructure, financing public services and amenities, and shifting investments from unsustainable to sustainable technologies. I discuss these in turn.
Child stunting, measured as low height for age, is associated with numerous health, cognition and productivity risks with potential intergenerational impacts.
and the pace of decline remains slow and uneven.
In Sindh, for example, things have worsened over time, with one in two children now stunted!
The policy response to this enormous health crisis has been almost entirely centered on interventions at the household level—reducing open defecation (OD), improving household behaviors like child feeding and care practices and food intake.
A recent World Bank report, which I co-authored, suggests that a major shift is this policy focus is required for significant progress on child stunting.
The report begins by showing that .
This has improved dietary diversity, even among the poorest, and increased household investment in a range of assets, including toilets within the home.
This has, in turn, led to a major drop in OD, from 29 percent to just 13 percent. Curative care has also expanded, with the mainstreaming of basic health units and the lady health worker program.
The World Bank’s recently completed Systematic Country Diagnostic highlights Romania’s vulnerability to natural disasters. Over the years, floods, droughts and earthquakes have cost the country thousands of casualties and billions of euros in damages to physical infrastructure. They have hurt the economy’s productive capacity and disproportionately affected the poor.
A vulnerable country
Countries around the world are already seeing evidence of the damaging impact of climate change, which is making past growth patterns unsustainable and reversing progress made on poverty reduction and shared prosperity.
Progress is being made in closing energy access gaps in Africa and Asia. A big reason is falling renewable energy costs, which have made home solar systems, mini-grids and other distributed renewable energy (DRE) solutions a viable option for providing first-ever electricity in remote, rural areas far removed from electric grids.
For the first time ever, the number of people gaining access to electricity in Sub-Saharan Africa is outstripping population growth. More than 700,000 home solar systems have been installed in Kenya alone and another 240,000 poor, rural households are expected to be connected soon under a new $150 million off-grid project backed by the World Bank. In South Asia, progress has been ever faster.
Such reluctance of many local financial institutions (FIs) to invest has been a major impediment to the Nigerian solar off-grid market which lags compared to other African countries such as Kenya.
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.
