While the 2008-2009 TBB program has chosen to focus on clean water issues in Ecuador, this certainly is not the only country where clear water is an issue. According to Food and Water Watch, 1.7 billion people around the world do not have access to safe drinking water.(1) That’s more than 1 of every 4 people on earth. For us geography buffs, this is an astonishing concept considering that the world’s surface is more than 2/3 water. What causes this? With all the water on earth and our modern technology, why can’t we solve this problem?
The problem of clean water is a dire one. Drinking from unsafe water supplies leads to 2.3 billion people suffering from water-borne illnesses each year.(2) Additionally, unsafe water weakens the immune system, making individuals and communities more susceptible to chronic and deadly diseases. As Paul Farmer points out in Tracy Kidder’s Mountains beyond Mountains, addressing global epidemics like tuberculosis, malaria, and AIDS requires addressing fundamental human needs like clean water. Also, access to clean water is closely related to food security. Agricultural communities around the world battle over water resources. Polluted rivers, lakes, and oceans produce fish that are poisonous to humans, often carrying toxic heavy metals like mercury in their flesh. As you’ve read this paragraph, you’ve probably seen at least one issue that is common to your community, even if you live in the “developed” world.
So, why is there such limited access to clean water? Consumption and pollution are the main culprits. As the global community grows (the population of the earth has TRIPLED since WWII ended) the consumption of water has greatly increased. While the Green Revolution and subsequent advances in agricultural technology made it possible to feed this growing population, these new farming methods required far higher water inputs. This means that not only do farmers need more water to grow more food, but the ratio of food output to water consumption has decreased. Yet another cause is the rapid urbanization of the global community. Hard, human-made surfaces send rainwater in its entirety into streams and rivers instantly after a storm. This disruption of the water cycle prevents absorption by the soil and the natural filtering effects of water seeping through layers of earth to the aquifer.
Pollution of water supplies originates from countless sources. The agricultural technology advances of the past 50 years mentioned above have often leaned heavily on the use of petrochemicals in the forms of fertilizers, pesticides, and herbicides to increase crop yields. Through irrigation and rain, a percentage of these chemical inputs makes its way to the water supply, either as run-off or by seeping into ground water supplies. Manufacturing and production of goods in factories often requires large amounts of water as a cooling or cleaning agent. The water leaving those factories often carries residues of the chemicals or heavy metals used in the manufacturing process. In homes around the world, water is rarely used by itself; soaps, cleaners, detergents, oils, paints, and countless other pollutants are used and discarded with water. As a global society, we have successfully integrated polluting water supplies into our daily lives.
While clean water is certainly an issue for people throughout the world (students of mine from inner-city Boston this summer told me that their parents insist on boiling the tap water because of the rancid smell and brown color when it comes from the tap), developing nations certainly face the worst of the problems. Crumbling or non-existent systems for water storage and delivery, and sewage removal and treatment leave few options for governments with already thin financial resources. Delivering clean water and properly dealing with sewage can be an incredibly expensive undertaking, especially when the needs are in both urban and rural communities. In the past decade, multi-lateral development agencies like the World Bank, International Monetary Fund, and World Trade Organization have been encouraging developing nations to privatize their water systems. The logic is that private firms will provide the capital investment to expand the existing systems to meet the current level of need. However, such attempts at privatization have met very mixed reviews. Cochabamba, Bolivia and Guayaquil, Ecuador both signed agreements with subsidiaries of San Francisco, California based Bechtel in 2000. Residents of Cochabamba awoke one morning that spring to find that their water rates had increased as much as 400%, bringing the total cost of water for many deeply impoverished residents to 25% of their total monthly income.(3) The agreement even made it illegal for citizens to collect rain water as it was considered part of the water resources leased to the company. Within days protests began, culminating in a horrific moment when a 17 year old boy in the crowd was shot by the National Police. The government was forced to cancel their contract with the Bechtel subsidiary and re-nationalize the water system. Guayaquil’s contract, signed only weeks after Cochabamba’s, has not been quite as tumultuous, though many human rights and environmental organizations site the water quality and sewage systems provided there as being completely inadequate and a danger to public health.(4)
What’s the solution? Unfortunately, it doesn’t seem as simple as finding just one solution. Rather, what is needed are many solutions, applied correctly, based on local conditions. William McDonough and Michael Braungart highlight the need for “eco-effective” design in their book Cradle to Cradle. They point out that most efforts to address environmental concerns—like providing clean water—are made after the polluting has already occurred. They argue that rather than continue to build technology and a society that makes messes and then struggles to clean them up, we should focus on developing technology that actually helps the environment. They give the example of a factory that, before using eco-effective design strategies, was a polluter of the already polluted local river. After finding non-toxic alternatives to many of the chemicals used in their manufacturing processes, and utilizing a series of biology-based waste treatment systems, the factory’s waste water going back into the river was actually cleaner than the river itself. Oh, and the company saved money in the process. Agricultural technologies like an underground drip irrigation system that Sandy and I saw demonstrated in Dethali, India can greatly reduce water and electricity consumption. The list of creative, local, and effective solutions is long. Ultimately, finding the correct solutions to providing clean water may simply require looking through eco-effective eyes.
