The earth might be getting greener

This is from NASA:

greening.png… the greening of the planet over the last two decades represents an increase in leaf area on plants and trees equivalent to the area covered by all the Amazon rainforests. There are now more than two million square miles of extra green leaf area per year, compared to the early 2000s – a 5% increase.

“China and India account for one-third of the greening, but contain only 9% of the planet’s land area covered in vegetation – a surprising finding, considering the general notion of land degradation in populous countries from overexploitation,” said Chi Chen of the Department of Earth and Environment at Boston University, in Massachusetts, and lead author of the study.

China’s outsized contribution to the global greening trend comes in large part (42%) from programs to conserve and expand forests. These were developed in an effort to reduce the effects of soil erosion, air pollution and climate change. Another 32% there – and 82% of the greening seen in India – comes from intensive cultivation of food crops.

If I were the president of the DRC, I would be seriously researching how Charlemagne did it (the medieval King ruled over a land mass the size of the DRC), how Brazil did it (their green revolution was a success) and how Vietnam is doing it (some people call it little China). I can bet my grad school stipend for next quarter that the younger Kabila has no local brain trust (who needs one if the Brussels boys can jet in and out of Kinshasa with copious amounts of “advice” on development??). The lets-just-stay-afloat-with-foreign-aid paradigm that informs governance in Africa is a guarantee that 50 years from now Africa will still be the poster child for bad governance and socio-economic underdevelopment.

Also, I just discovered a blog by The Bank’s chief economist for Africa region. Check it out (via Blattman).

Lastly, Wronging Rights has a post on the series of post by Texas in Africa on how social science works.

africa’s population – the economist’s view

The Economist has two interesting pieces on the demographic trends in Africa. The first article notes that the fertility rates on the continent are finally beginning to come down. The second one discusses the chances that Africa will take advantage of the democratic dividend and execute its own green revolution.

As I have argued before, there is a great deal of economic sense in bringing population growth on the Continent under control – at least until people’s life options have been increased enough so that they can make well informed choices on the number of offspring to have. The usual critics of family planning measures – the Church and conspiracy theorists – should take some time to visit slums or rural homes in which overburdened, dis-empowered daughters of the Continent with little or no economic wherewithal run
