"Eliminating water shortages depends on a global attempt to raise water productivity similar to the effort launched a half-century ago to raise land productivity, an initiative that has nearly tripled the world grain yield per hectare." –Lester R. Brown, World Facing Huge New Challenge on Food Front in Plan B 3.0: Mobilizing to Save Civilization
Chapter 7. Eradicating Poverty, Stabilizing Population: Curbing the HIV Epidemic
Although progress is being made in curbing the spread of HIV, 4.3 million people were newly infected in 2006. More than 40 million have died from AIDS thus far, two thirds of them in Africa—the epicenter of the disease. 56
The key to curbing the AIDS epidemic, which has so disrupted economic and social progress in Africa, is education about prevention. We know how the disease is transmitted; it is not a medical mystery. In Africa, where once there was a stigma associated with even mentioning the disease, governments are beginning to design effective prevention education programs. The first goal is to reduce quickly the number of new infections, dropping it below the number of deaths from the disease, thus shrinking the number of those who are capable of infecting others.
Concentrating on the groups in a society that are most likely to spread the disease is particularly effective. In Africa, infected truck drivers who travel far from home for extended periods often engage in commercial sex, spreading HIV from one country to another. Sex workers are also centrally involved in spreading the disease. In India, for example, educating the country’s 2 million female sex workers, who have an average of two encounters per day, about HIV risks and the life-saving value of using a condom pays huge dividends. 57
Another target group is the military. After soldiers become infected, usually from engaging in commercial sex, they return to their home communities and spread the virus further. In Nigeria, where the adult HIV infection rate is 4 percent, former President Olusegun Obasanjo introduced free distribution of condoms to all military personnel. A fourth target group, intravenous drug users who share needles, figures prominently in the spread of the virus in the former Soviet republics. 58
At the most fundamental level, dealing with the HIV threat requires roughly 13.1 billion condoms a year in the developing world and Eastern Europe. Including those needed for contraception adds another 4.4 billion. But of the 17.5 billion condoms needed, only 1.8 billion are being distributed, leaving a shortfall of 15.7 billion. At only 3.5¢ each, or $550 million, the cost of saved lives by supplying condoms is minuscule. 59
The condom gap is huge, but the costs of filling it are small. In the excellent study Condoms Count: Meeting the Need in the Era of HIV/AIDS, Population Action International notes that “the costs of getting condoms into the hands of users—which involves improving access, logistics and distribution capacity, raising awareness, and promoting use—is many times that of the supplies themselves.” If we assume that these costs are six times the price of the condoms themselves, filling this gap would still cost only $3 billion. 60
Sadly, even though condoms are the only technology available to prevent the sexual spread of HIV, the U.S. government is de-emphasizing their use, insisting that abstinence be given top priority. While encouraging abstinence is desirable, an effective campaign to curb the HIV epidemic cannot function without condoms. 61
One of the few African countries to successfully lower the HIV infection rate after the epidemic became well established is Uganda. Under the strong personal leadership of President Yoweri Museveni, the share of adults infected dropped substantially during the 1990s and has remained stable since 2000. Senegal, which acted early and decisively to check the spread of the virus and which has an adult infection rate of less than 1 percent, is also a model for other African countries. 62
The financial resources and medical personnel currently available to treat people who are already HIV-positive are severely limited compared with the need. For example, of the 4.6 million people who exhibited symptoms of AIDS in sub-Saharan Africa in 2006, just over 1 million were receiving the anti-retroviral drug treatment that is widely available in industrial countries. Although the number getting treatment is only one fourth of those in need, it is double the number treated during the preceding year. 63
There is a growing body of evidence that the prospect of treatment encourages people to get tested for HIV. It also raises awareness and understanding of the disease and how it is transmitted. And if people know they are infected, they may try to avoid infecting others. To the extent that treatment extends life (the average extension in the United States is about 15 years), it is not only the humanitarian thing to do, it also makes economic sense. Once society has invested in the rearing, education, and on-job training of individuals, the value of extending their working lifetime is high. 64
Treating HIV-infected individuals is relatively costly, but ignoring the need for treatment is a strategic mistake simply because treatment strengthens prevention efforts. Africa is paying a heavy cost for its delayed response to the epidemic. It is a window on the future of other countries, such as India and China, if they do not move quickly to contain the virus that is already well established within their borders. 65
