Life in the Slow Lane - The Nairobi Grind

Apurva Sanghi's picture

I’ve lived in cities famed for their gridlock: 1990s Bangkok (gridlock was as bad as it could be); Los Angeles (gridlock + pollution); New Delhi (gridlock + pollution + honking galore); Nairobi’s gridlock is surely up there.

But is traffic “bad”? What sort of question is that you ask? Surely, the answer is 'yes', you say: time wasted stuck in traffic, the frustration, the needless idling of vehicles which creates both local (and global) pollution and so on. But let me suggest this: traffic congestion is also a sign of development. In fact, the more vibrant and dynamic the city as Nairobi surely is, the more traffic congestion you might paraphrase Gordon Gekko from the movie Wall Street, “Traffic is…good”!

Why should Governments Spend on Sanitation?

A puzzle:  Sanitation is one of the most productive investments a government can make.  There is now rigorous empirical evidence that improved sanitation systems reduce the incidence of diarrhea among children.  Diarrhea, in turn, harms children’s nutritional status  (by affecting their ability to retain nutrients).  And inadequate nutrition (stunting, etc.) affects children’s cognitive skills, lifetime health and earnings.  In short, the benefits of sanitation investment are huge.  Cost-benefit analyses show rates of return of 17-55 percent, or benefit/cost ratios between 2 and 8.

But if the benefits are so high (relative to costs), why aren’t we seeing massive investments in sanitation?  Why are there 470 million people in East Asia, 600 million in Africa and a billion people in South Asia lacking access to sanitation?  Why are there more cellphones than toilets in Africa?
