What Baltimore Gets Right about Urban Trees

While some parts of the United States struggle with drought, others are faced with more water than they know what to do with. Minnesota reconstructs roads and drainage systems in order to be more prepared for the large amounts of rain fall they have received, largely due to climate change.

Concerned with colony collapse syndrome in honey bees worldwide, scientists, farmers and tech companies teamed up in Australia to create a micro-sensor that collects data on the bee's environment.

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.

In Colombia, traditional cattle pastures have caused soil degradation, deforestation, and desertification. To reconcile this, several thousand acres of land in Latin America have been transformed into a silvo-pastoral system of grazing and raising cattle with agro-forestry. The Colombia-based Center for Research in Sustainable Systems of Agriculture seeks to reduce pasture land by 26 million acres while increasing cattle numbers by 2019.

For the past three years, water levels in the San Antonio Edwards Aquifer have decreased to uncomfortable levels and drought periods may continue as the population booms.

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 the Mumbai slum of Dharavi, an NGO called Society for Nutrition, Education & Health Action (SNEHA) is working to make life safer by teaching men the importance of not being violent towards women.
