How Detroit Taught Itself to Demolish Vacant Houses Safely

During rain seasons in Bangladesh, rivers flooded villages and their agriculture so that local economies and food supplies were in jeopardy. A Bangladeshi non-profit Shidhulai Swanirvar Sangstha introduced small floating farms designed to be run by women. Consequently, the organization has initiated 40 floating farms that serve 300 rural women and save local agriculture.

At the Fujitsu factory in Japan, a significant decline in demand for semiconductor computer chips meant the company had large empty factory space sitting unused. A new business approach allowed them to dually address both the need to evolve their business model with a global decline of viable agricultural space needed to grow the world's food. Now, the factory houses indoor vegetable gardens, soil free and less resource-heavy than traditional farmland.

Climate change has led to shorter, more violent rainy seasons in the highlands around Lima, Peru, meaning that - even though there is theoretically enough water during the rainy season to sustain the local population, it flows downhill too quickly, leaving residents short of clean water during the dry season. Now, an organization called Condesan is helping the community to restore ancient stone canals from the seventh century that will help to store water from rainfall through the dry season and supply residents with a steady water source.

With the prices of solar technology dropping and the opportunity to save drastically on energy usage and costs, businesses and organizations across the country are investing more in solar infrastructure for their buildings and facilities. The Better Buildings Initiative of the US Department of Energy is helping by providing guidance and documenting effective approaches and financing for renewables installations - from hotels, to schools, to big box retail.

The consumption of meat and dairy has long been deemed a leading cause of climate change, yet production continues to rise. To contribute to environmental sustainability, Dale Vince – owner of the U.K.’s Forest Green Rovers soccer team – has achieved the status of having the world's first carbon neutral team. From vegan-only menus to a solar-powered grass-cutter, the organization is bringing light to this topic in front of a new audience.

The Anacostia, which has long been one of the most polluted rivers in the country, has been given a new lease on life, thanks to cleanup efforts and a recent sewer upgrade in D.C. Since water quality has improved, there's been renewed interest in waterfront recreation and development. Now local groups are working to mitigate displacement from gentrification, with some success.

Pennsylvania law is preventing a Philadelphia neighborhood from converting an empty lot into a solar farm, but community members are working to fight against this by citing neighboring states that are seeing positive impact from similar projects. One such project is in Massachusetts where shared solar energy systems is helping to offset "80 percent of the power needs of a nearby assisted living facility, an affordable housing development, a family-owned hardware store and a non-profit serving those with disabilities."

Fly ash bricks help reduce construction waste by utilizing the powdery by-product of burning coal. They are a green replacement for red clay bricks, which contribute to 5-15% of India’s emissions. They also utilize waste from coal-based thermal plants, which often gets disposed of by being dumped in water bodies and on roadsides. In comparison to red clay bricks, fly ash bricks are less expensive and the production process doesn’t emit smoke or use the more fertile top soil. Their use has been mandated by some regions and about 150 small fly ash enterprises have emerged.

As building developers in Kenya design new structures that are more environmentally friendly and sustainable, they can look to the Garden City Mall in Nairobi as a successful example. This mixed-use development with shopping, residential, and office spaces uses solar energy, which helps cut energy costs by over 30 million shillings each year. The mall also was the first in the region to receive an international green building certification.

Hempcrete, a combination of hemp, water, and lime, can be used as a more sustainable insulation option for buildings. The material improves energy efficiency, produces less carbon than options like fiberglass and foam, and will continue to capture carbon while used as insulation.
