Designing the Butterfly-Friendly City

Poor neighborhoods in the United States lack quality play spaces for children, also known as play deserts. An organization is enabling communities across the nation to build their own playground.

Great minds from Plato to Piaget have recognized the importance of play in healthy child development, but with bullying becoming more prevalent on school playgrounds and increased pressure to maximize school hours to boost performance on standardized tests, schools are struggling to implement meaningful recess. Playworks and other similar non-profit groups provide coaching for adults on how to help structure children's playtime to be healthy, productive, and enjoyable, while allowing children to explore on their own and develop positive relationships.

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.

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.

A growing number of people in the famously crowded Tokyo metropolis are becoming ‘city farmers’, planting crops atop tall buildings or deep underground. In an age of detrimental climate change, urban cultivation and green roof agriculture will soon be necessary as food, water and energy resources become scarcer.

Passive houses can generate more energy than they consume but are expensive to build. Non-profits across the nation are getting low income families into these types of renewable homes with state subsidies and volunteer work.

Cities across the world, suffering from increased threats of floods and droughts due to climate change, are finding new ways to manage water, such as reclaiming natural waterways and increasing on spot water absorption.

Too much solar and wind power in Germany is overloading their grid. A firm developed a new technology that uses super-fast batteries and software to hold intermittent wind and solar power when more than needed is generated.

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.

Despite strong evidence that school-based physical activity improves children’s cognitive skills, concentration, and behavior, schools under pressure to produce quantitative results and decrease bullying have drastically cut back on recess in recent years. An Oakland-based nonprofit organization called Playworks is working to make healthy play accessible for more children and show schools how productive recess can be to the whole academic world.
