The travel doctor gave me a tincture of iodine kit to disinfect water, if needed, when I was in Tanzania. I never had to use it though because bottled drinking water was available everywhere.
But, that is also the source of one of Tanzania’s environmental problems—empty plastic bottles all over the place. By the highways, beaches, and in open drains.
One might hypothesize that collecting such recyclables will be a source of income to the hard-working poor, which is the case in India. But, I suspect that Tanzania lacks a robust industrial base to offer the necessary economic incentives for the poor to turn all that plastic into cash.
The litter problem was, however, nothing compared to the more pressing smoke pollution.
I spent most of my time in Tanzania in a village, Pommern, in the southern highlands. It was a two-hour drive from Pommern to the nearest town, Iringa, which itself is a little more than 300 miles from Dar es Salaam. Pommern is up in the hills—I was at close to 6,500 feet elevation for most of my time in Tanzania.
With red soil on the rolling hills, and fascinating flora that included “sausage trees,” Pommern was absolutely picturesque indeed. But, at the same time it was hard to get away from smoke.
There were two primary sources of smoke. One came from the rubbish that was burnt, well, practically everywhere in the village. The smoking piles included plants that were cleared away, and even plastic bottles and batteries.
But, the smoke and smell from such trash incineration was secondary to the noxious clouds from wood and charcoal burning, which is how the village’s energy needs are met.
In a country of 37 million people, barely ten percent of the population has access to electricity, and that is mostly in urban Dar es Salaam, while more than 80 percent of the population lives in rural areas like Pommern where electricity is rare. And gas for cooking is rarer even within Dar es Salaam
Thus, most of the population relies on charcoal and firewood for cooking--the World Bank recently estimated that about one million tons of charcoal are consumed every year in Tanzania. This amount is projected to increase even more due to the fact that electricity and gas are not available for the growing population.
Charcoal making itself, therefore, is an important economic activity. Charcoal, of course, comes from trees and is preferred over firewood because it is easy to store and transport, and offers more energy than a comparable weight of firewood. It was quite common to see young men selling bags of charcoal all along the drive in the rural and forest areas that dominate Tanzania’s landscape outside Dar es Salaam.
But, both charcoal and firewood are often used in remarkably inefficient settings that generate a lot more smoke than usable heat. Often, the “stove” is nothing but a traditional fireplace with three stones.
Women, and children too, are often present around these smoking stoves. As one can imagine, such a constant inhalation of carbon dioxide, carbon monoxide and other gaseous chemicals, along with the tiny particulate matter can be devastating for health. Which is why “Acute Respiratory Infection” (ARI) is a leading public health problem in this beautiful mountainous setting, along with HIV and malaria.
This has not gone unrecognized. The Improved Charcoal Stove (ICS) was introduced in Tanzania in 1988, and research continues in developed and developing countries alike on designing more efficient firewood and charcoal burning stoves.
It was, thus, with a gladdened heart along with local pride that I read, after returning home, the essay in the New Yorker magazine, which was also referred to in a recent editorial in this newspaper. The New Yorker featured the Aprovecho Research Center—right here in Oregon—which has won international recognition for its efforts to design better stoves that would also be inexpensive.
My academic discussions with students about the more than 2.5 billion people who depend on wood and charcoal as the source of energy pale next to experiencing it everyday amidst an otherwise, and ironically enough, gorgeous setting on this blue planet of ours.
I bet the people of Pommern, along with other billions can’t wait for the kitchen upgrade. Go Aprovecho!
