Good News on Malaria Control [Extended version] One of the persistent questions about sustainable development is how to help the world s poorest people. Their incomes are so low that they lack access to the most basic goods and services: adequate nutrition, safe drinking water and sanitation, and life-saving health interventions. One strategy, which I have long favored, is to provide targeted financial support to help the poor to meet their basic needs and thereby to escape from the poverty trap. My colleagues and I have calculated that the cost of ensuring basic life-saving health coverage for the world s poor would be around 0.1 percent of the gross national product of the high-income countries (10 cents per $100 of income). One example of such targeted aid is a mass free distribution of antimalaria bed nets to people living in impoverished malarious regions of Africa. Each of these long-lasting insecticide-treated nets (LLINs) costs only around $10 to produce, transport and distribute to households in rural Africa. Because the nets last for five years and two children typically sleep under each net, the cost per child per year is a mere $0.50. Even at this remarkably low cost, however, some critics have opposed such an approach. They have claimed that the nets would go missing in large numbers because of waste by recipients and others in the supply chain who did not properly value them. These critics preferred solution is market sales of nets at a discount rather than a massive free distribution, on the grounds that even a small price would encourage more efficient use of the nets.

Crew of Ocean Watch Docks in New York to Share Data and Stories from Voyage around Americas Waters in the Gulf of Alaska were surprisingly acidic this summer, an indication they are absorbing high levels of carbon dioxide . Farther north, a polar bear in search of food wandered dangerously close to a town where it would have been killed. And along the Northwest Passage from Alaska to Greenland, Inuit people told stories of their ice becoming too thin for them to walk across. [More] rss.sciam.com |
