I love the TV show “The Big Bang Theory.” It gives a sympathetic view of geeks, where the nerdy guy gets the beautiful girl—I just wish it had been made when I was in high school. I was the geek, without the chic. At the mercy of the big, macho kids, who seemed to have gone through puberty years before I even knew what the word meant.
I thought I had left all of that in high school, but there is a tendency in PPP to perpetuate the macho stuff. Let’s take toll roads as an example. A few frustratingly macho myths about toll roads that only a geek can bust:
The World Region
How large is the share of public procurement to GDP in middle-income and low-income countries and how it is evolving? If sizable, can public procurement be used as a policy tool to make markets more competitive, and thus improve the quality of government services? Can it be used to induce innovation in firms? Can it also be a significant way to reduce corruption?
In Sub-Saharan Africa and South Asia, there are more than twice as many students per teacher than in Europe and North America. The pupil-teacher ratio is different but related to class size, and is often used to compare the quality of schooling across countries.
A few years ago, when Craigslist was just “The List,” a friend circulated an ad posted on Craigslist Vancouver. It went like this:
We are a small & casual restaurant in downtown Vancouver. We are looking for solo musicians to play in our restaurant to promote their work and sell their CD. This is not a daily job, but only for special events, which will eventually turn into a nightly event if we get positive response. More jazz, rock, & smooth-type music around the world and mixed cultural music. Are you interested in promoting your work? Please reply back ASAP.
And one of the responses received was:
I am a musician with a big house looking for a restauranteur to promote their restaurant and come to my house to make dinner for my friends and me. This is not a daily job, but only for special events, which will eventually turn into a nightly event if we get positive response. More fine dining & exotic meals and mixed ethnic fusion cuisine. Are you interested in promoting your restaurant? Please reply back ASAP.
It’s perhaps unfair to conclude that the restauranteur didn’t mean well. But what does this exchange suggest? How are the arts normally valued, consciously or unconsciously, in our social order?
I recently took part in #skipthegrid, a social media forum about renewables, which has led me to ask: “Is off-grid the way of the future for energy Public-Private Partnerships (PPPs) in lower-income countries?”
At the Private Infrastructure Development Group (PIDG) we are supporting smaller, off-grid projects in the lowest income countries in Sub-Saharan Africa and South and Southeast Asia by mobilizing private investment for the provision of power to commercial off-grid properties and the construction of mini-grids.
Presently, the average annual loss from natural disasters in cities is estimated by the UN at over $250 billion. If cities fail to build their resilience to disasters, shocks, and ongoing stresses, this figure will rise to $314 billion by 2030, and 77 million more city dwellers will fall into poverty, according to a new World Bank/GFDRR report presented at COP22.
The good news is that we have a window of opportunity to make cities and the urban poor more resilient. Over 60% of the land projected to become urban by 2030 is yet to be developed. Additionally, cities will need to build nearly one billion new housing units by 2060 to house a growing urban population. Building climate-smart, disaster-resilient cities and housing is thus an immediate priority, especially in the developing world.
To seize that opportunity, countries will need significant financing for infrastructure—over $4 trillion annually—and making this infrastructure low carbon and climate resilient will cost an additional $0.4 to $1.1 trillion, according to a CCFLA report.
Mobilizing private capital is the best bet for helping to close this financing gap.
Population density is one of the most important statistics for development efforts across many sectors, and since early 2016 we’ve been collaborating with Facebook on evaluating a new source of high-resolution population data that sheds light on previously unmapped populations.
As mentioned in the Living Standards Measurement Study (LSMS) team’s blog post, Facebook Connectivity Lab announced last week the public release of high-resolution population maps for Ghana, Haiti, Malawi, South Africa, and Sri Lanka, jointly produced with the Center for International Earth Science Information Network (CIESIN).
With the building footprints detected by artificial intelligence (AI) over high-resolution commercial satellite imagery, the data sets provide estimates of population at 30m spatial resolution, making these maps the highest-resolution population maps ever produced. This is only possible through recent breakthroughs in computer vision due to deep learning algorithms and technological development of computer processors, as well as the increasing availability of high-resolution commercial satellite imagery.

Facebook recently announced the public release of unprecedentedly high-resolution population maps for Ghana, Haiti, Malawi, South Africa, and Sri Lanka. These maps have been produced jointly by the Facebook Connectivity Lab and the Center for International Earth Science Information Network (CIESIN), and provide data on the distribution of human populations at 30-meter spatial resolution. Facebook conducted this research to inform the development of wireless communication technologies and platforms to bring Internet to the globally unconnected as part of the internet.org initiative.
Figure 1 conveys the spatial resolution of the Facebook dataset, unmatched in its ability to identify settlements. We are looking at approximately a 1 km2 area covering a rural village in Malawi. Previous efforts to map population would have represented this area with only a single grid cell (LandScan), or 100 cells (WorldPop), but Facebook has achieved the highest level of spatial refinement yet, with 900 cells. The blue areas identify the populated pixels in Facebook’s impressive map of the Warm Heart of Africa.
Facebook’s computer vision approach is a very fast method to produce spatially-explicit country-wide population estimates. Using their method, Facebook successfully generated at-scale, high-resolution insights on the distribution of buildings, unmatched by any other remote sensing effort to date. These maps demonstrate the value of artificial intelligence for filling data gaps and creating new datasets, and they could provide a promising complement to household surveys and censuses.
Beginning in March 2016, we started collaborating with Facebook to assess the precision of the maps and explore their potential uses in development efforts. Here, we describe the analyses undertaken to date by the Living Standards Measurement Study (LSMS) team at the World Bank to compare the high-resolution population projections against the ground truth data. Among the countries that were part of the initial release, Malawi was of particular interest for the validation exercise given the range of data at our disposal.
The UN estimates that 2.4 billion people still lack access to improved sanitation facilities, nearly 1 billion of which practice open defecation. Good sanitation is a foundation for development - conditions such as diarrhea are associated with poor sanitation, and left untreated, can lead to malnutrition and stunting in children.

In our last post, we highlighted a few examples of the innovative organizational structures that institutional investors have created to more efficiently invest in public infrastructure assets, but that is just one side of the equation. We also study programs and policies put in place by governments to more efficiently facilitate investment in the right projects and on the right terms for their constituents. That research encompasses several different topics, including enabling legislation, project risk allocation, stakeholder engagement and management, assessment frameworks for determining whether a Public-Private Partnership (P3) makes sense for a given project and others.
