While attending the CITES (Convention on Trade in Endangered Species) biodiversity summit in Nagoya, Japan, late last year, World Bank President Robert Zoellick said that we must foster development and reduce poverty, and at the same time preserve and improve the planet’s biodiversity and ecological resilience.
He noted during a speech at the Cancun COP16 Climate Convention that “empty forests are greatly diminished.” He is completely right, but globally efforts to achieve ecologically sustainable development have been difficult and fraught with failure. Sadly, to some the issue is yet another complication to be ignored or avoided.
I spent this weekend at the Mpala Research Center, in Laikipia, central Kenya, which is a remarkable partnership with the National Museums of Kenya, its local partners in Laikipia district, the Smithsonian Institution, and Princeton University in the United States.
Mpala is very dear to me. Working more than a decade ago with a remarkable doctoral student of mine who is now a professor, Majid Ezzati, and a fabulous team of local Kenyan medical and energy researchers and extension officers, we completed a detailed “dose-response” study of the health benefits of improved cookstoves. We found that while initial particulate levels were very high–7,000 or more micrograms of particulates per cubic meter (mg/m3)–combinations of improved stoves and clean burning fuels could reduce the incidence of acute respiratory illness by 50%.
