A Vision of Vertical Slums in Mumbai

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.

In Memphis, a creative blight-reduction initiative called 25 Square Blocks broke down the city into blocks. Inspectors were able to quickly identify all the violations and fix them, using the same amount of funding, but less time, as the old call-and-respond model.

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.

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. The San Antonio Water System organization has set up rules to limit water use and has recycled water for conservation frugal innovation.

As a state with robust populations of wildlife, Montana has had its share of roadkill. Its Department of Transportation developed animal shelving, a type of wildlife crossing, to enable safe passage for small animals who need to cross the road. The measure, combined with other types of crossings, has reduced animal-vehicle collisions by half.

New York City suffered from fires that erupted in overcrowded, run-down apartments. Then the city sleuthed through residential records and found that landlords who foreclosed let their properties fall apart and ignored safety-code violations. Greater Toronto wants to expand upon New York City’s method by using transportation surveys, census data and computer data to build transit lines.

Tulsa Public Schools drew on expertise across many sectors and extensive neighborhood input to address the issue of thousands of empty seats in local schools. Through a community-focused process, they were able to mindfully close under-utilized schools and better maximize the community's resources for students.

A Dallas urban neighborhood was dilapidated with abandoned storefronts and offered no vitality for pedestrians. A group of artists and community members created Build a Better Block, in which local artisans and small businesses took over a vacant block and transformed it for a limited time to encourage the ingredients for more permanent urban renewal.

While billions of taxpayer dollars are allocated each year to support shelters and social service initiatives, homelessness remains a persistent problem in the U.S. - in 2013, an estimated 610,000 people slept without shelter every night. All over the country, people are building "tiny homes" to give to the homeless, providing them with shelter, a bathroom, and a kitchen for less then the cost of a shelter.

Renovating and furnishing a home can be hugely expensive. Homeowners who are renovating on a budget, and want to do so in a way that is evironmentally friendly, can find recycled luxury kitchens and other lightly used fixtures at stores like Green Demolitions.
