Rwanda Eyes Biogas to Help Curb Deforestation

Nationally, only about a third of municipal solid waste is recycled. An initiative to use simpler, standardized signs and labels is helping communities reap greater benefits from recycling.

Evidence continues to build that humans are contributing to a climate change issue that is nothing but bad news for the planet. Hopeful stories from seven countries, including India, Indonesia, and China, show that efforts to combat climate change might finally be working.

Summer in the Northwest presents a great risk of wildfires. A pile burning operation, just one facet of the strategy that Oregon has enacted to conserve its forests, clears undergrowth to lessen the risk of mega-fire. The work stimulates the local economy and provides employment, but it's also a very small part of what needs to be done.

Geography and climate change challenge the viability of sea-level cities in Vietnam, but architects, researchers, and urban planners work together to find creative solutions. One architect in Ho Chi Minh City designed green roofs to absorb the rainwater that causes floods.

Lack of access to sanitary bathrooms in the village of Kivalina, Alaska led to the implementation of a novel, home-based water sanitation system, currently being tested for effectiveness. The hope is that it proves to be a solution for areas all over the state with lack of access to clean water systems.

New York City black tar roofs cause a number of environmental problems, including air pollution, heat absorption that raises energy consumption, and storm water runoff in the sewer system. Efforts to turn these old roofs into green spaces cool the buildings, enable the containment of more rainfall, reduce sewer discharge, generate energy, and absorb carbon emissions. New York City has a pilot program offering financial help for green roofs.

Throughout India, wastepickers – people who scour landfills for garbage they can sell to recyclers – live at the bottom of society. But the city of Pune did something radical: with the help of a collective, they did away with expensive garbage trucks, and now all household garbage is collected by wastepickers with pushcarts. Pune saves millions of dollars each year and recycles more – and the wastepickers have decent wages and social standing. The concept is now spreading globally.

In Africa, many people rely on wood from trees to cook food over stoves. The tremendous usage of wood contributes to deforestation and environmental decline. Using bamboo instead of wood is a more profitable and greener solution.

In war zones, people have a difficult time finding clean water and safe areas to inhabit. Social media, smart phones, and technology applications are aiding in people’s survival. In Aleppo, Syria, the International Committee of the Red Cross posted a map on Facebook to show alternative sources of clean drinking water that reached approximately 140,000 people.

In India, 620 million people openly defecate outdoors, causing harm to hygiene, sanitation, food, and water resources. The president of India funded an initiative to build public toilets for the people in his country, but the people did not use them because of traditions and behaviors. The Total Sanitation Campaign is starting to change villagers’ minds by having local leadership persuade those who resist the toilets by holding community activities and creating special committees to maintain the sanitation.
