To grow or not to grow: In Fort Collins, a warning for Bozeman's future?

Raton, a town once surrounded by eight coal mines, now has a main street of boarded-up buildings. There is reason for optimism as the town diversifies its local economy, betting on "a mix of small manufacturing businesses, health care and specialty services, and hospitality for travelers" to endure the sudden decline in mining revenue. Its calculated revitalization may hold lessons for other towns.

As Beijing grapples with pollution caused in large part by the increase in cars on the roads, a tech-based solution has appeared in the form of forward-thinking bicycles. The Chinese bike-sharing system, spearheaded by several startups, allows commuters to find a bike using GPS, pay for it using an app, and drop it off upon arriving to their destination, wherever that may be. A mix of private investment and government support has allowed this market to thrive.

Copenhagen is a highly livable city, thanks to policies that focus on making streets safe and convenient to walk. The bigger the city, the worse it is to design urban spaces only with cars in mind, says planner and architect Jan Gehl. His top advice is to gather data about people and their movements, making pedestrians as visible in city planning as automobile traffic.

Bozeman, Montana, a city grappling with how to plan for growth in a smart and strategic way, is looking to learn from Fort Collins, Colorado. The two cities are similar in terms of the features that make them appealing: once low-cost, small college towns with beautiful scenery and lots of space. Now, Fort Collins’ population has soared, and critics say development could have been smarter. Bozeman is learning lessons about planning and inclusivity, hoping not to make the same mistakes.

The focus on sound comes at a time when open kitchens and industrial hard-surface designs entice diners’ eyes, but might strain their ears.

A tiny home and RV community outside of Austin, Texas does more than house the homeless; it provides community and economic independence.

Innovative mine reclamation projects across five states in the Appalachian region allow local organizations, schools, and businesses to clean up and utilize abandoned mine land. From a school that's transforming abandoned mine land into a field of solar panels to a housing development project that uses abandoned mine federal grant money to build affordable and energy efficient housing, the Appalachian region is using a comprehensive approach to renew blighted mines.

Redeveloping and repurposing unused real estate provides a path toward economic revitalization. With a combination of public and private grants, the nonprofit group, International Sonoran Desert Alliance (ISDA), has purchased and redeveloped real estate in the town of Ajo, Arizona. The renovated town plaza and Curley School complex contain retail spaces, artist studios, and even house community gardens of the Ajo Center for Sustainable Agriculture.

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."

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.
