How to build homes that can fight climate change — and survive its effects

The Western Hemisphere’s biggest city has developed a model blueprint for progressive housing policy in developing countries, in large part by affirming squatters' rights and demanding a certain percentage of low-income housing in new developments.

Eight years after a mercaptan spill in Eight Mile, Alabama, its mostly black and working class residents still suffer from respiratory issues, rashes and headaches.

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.

American humanitarian aid and programs by the United Nations have proved beneficial to equip Middle Eastern refugees with resources for self-settlement outside of camps. The self-settlement model has empowered refugees to become more productive members of society when they return home.

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.

Refugee camps typically look like a prison with squalid conditions and barbed wire tops. By contrast, the Kilis refugee camp in Turkey is orderly, secure, and clean; has schools for children; has grocery stores, and is powered with electricity. The camp is not run by the United Nations, but rather it is Turkey’s Disaster and Emergency Management Presidency that oversees every detail and pours billions of dollars into maintaining it every year.

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.

In the wake of Hurricane Sandy, necessity has bred an interesting kind of financial invention for the New York MTA: the world’s first “catastrophe” bond - a reinsurance for the insurer - designed to protect public transportation infrastructure, specifically against storm surge. These bonds privatize risk for public gain, creating a kind of tool that may protect economic development against all kinds of natural and man-made disasters around the world.

In a country of limited resources — and perhaps for that very reason — preparing for natural disasters is top of the agenda in Bangladesh. Various grassroots, collaborative programs have been put in place over the years to help address many facets of the calamities caused by cyclones, from improved emergency shelters to long-term support for those who lose their livelihoods in the storms.
