Water Education

Clean water is essential for life, but most people in the developed world don’t think much about the water they use for drinking, food preparation, and sanitation. In developing nations, however, the search for safe drinking water can be a daily crisis. Millions of people die each year, most of them children, from largely preventable diseases caused by a lack of access to clean water and proper sanitation.

Much progress is possible. In fact, due to the dedicated efforts of governments and NGOs since the 1992 Earth Summit, safe drinking water has been made available to some 1.7 billion people around the world, with projects ranging from modern piped plumbing to rainwater collection and storage.

About 5,000 children die each day due to preventable diarrheal diseases such as cholera and dysentery, which spread when people use contaminated water for drinking or cooking. A lack of water for personal hygiene leads to the spread of totally preventable ailments like trachoma, which has blinded some six million people.

Water woes also trap many low-income families in a cycle of poverty and poor education—and the poorest suffer most from lack of access to water. People who spend much of their time in ill health, caring for sick children, or laboriously collecting water at distances averaging 3.75 miles (6 kilometers) a day are denied educational and economic opportunities to better their lives.

Competition can be fierce for this precious commodity. Agriculture claims the lion’s share of freshwater worldwide, soaking up some 70 percent, and industrial uses consume another 22 percent. Watersheds and aquifers don’t respect political borders and nations don’t always work together to share common resources—so water can be a frequent source of international conflict as well.

 

Many opportunities exist to use the water we do have more productively. Change begins with more efficient management of water resources.

“Seventy percent of all the water we use globally is for agriculture, so that’s where we first have to become a lot more efficient through methods like drip irrigation and growing crops that are more suitable to the local climate,” Postel said. “We still have too few incentives for farmers to use water more efficiently. Farmers are good businesspeople; they respond to incentives that affect their bottom line.”

The United National General Assembly has recognized “the right to safe and clean drinking water and sanitation as a human right that is essential for the full enjoyment of life and all human rights.” Making that right become a universal reality, and providing each person on the planet with affordable access to the 20 to 50 liters of daily water required to sustain life, is a clear goal for the decades ahead.

I really like this article because a friend of mine used to work within the U.N and would talk to me about the sustainability goals. I would assist her in her work sometimes, gathering information on the state of water around the world. Its important to not the gaps with education and the impact that can have on a country.

Greenbelts and Nitrogen Dioxide

In “Roadside trees trap asthma-inducing pollutants“, a new study challenges the popular notion that having more trees automatically means having cleaner air.  A new study looked at the wooded areas net to roadways. A common pollutant from vehicle exhaust, nitrogen dioxide,  may be trapping it and causing the ground levels to as much as 21%. Nitrogen Dioxide can make it harder to  breathe for people with respiratory disorders.

Urban Ecologist Heikki Setälä from the University of Helsinki measured air quality in and around 10 greenbelts. After taking these measurements, they found that percentages of Nitrogen Dioxide were on average; 14% higher than in the fields some distance away from it. Setälä suggested that wind might be the cause in the study. The denseness of the trees make it more difficult for pollutants to disperse.

I was attracted to this article because of how it challenges the belief that to combat climate change and pollution, we just have to plant more trees. We have to be more strategic with how we implement environmentally friendly infrastructure.  As noted by Sara Janhäll, who says, “We can use vegetation much more than we do, but the design can be totally wrong, and then you won’t get an air pollution-reducing effect.”
