'Our plan worked': How Vienna prepared itself for a 5,000-year flood

CitiStat has show great success in cities like Baltimore, where it has improved city services' efficiency (removing snow, fixing potholes, etc.). Many cities use Stat programs, but Baltimore has been a particular case of success. Looking at how it implemented its CitiStat program holds lessons for other cities.

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.

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.

Louisiana and Vietnam both need affordable solutions to rising sea levels. Leaders from Vietnam visited Louisiana to compare ideas.

Bangladesh is fighting rising sea levels due to climate change. It's doing so with the help of foreign money and Dutch-inspired engineering.

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.

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.

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.

After the drought hit Australia in the early 2000s, city officials had to start thinking seriously about ways to conserve and creatively store their water. External tanks became the solution, storing rain runoff to create an available source of water for Melbourne residents. This solution may not fit every location, but there are other teachable lessons such as taking radically shorter showers.
