Fariel Salahuddin was determined to tackle the extreme lack of access to fresh water she encountered in rural Pakistani communities, but she wanted the model to be sustainable, not dependent on donations. Most of the communities didn't have regular access to rupees to help sustain their solar water pump micro-enterprises - what they did have, however, were goats. Salahuddin set up a scheme where villagers could pay for their clean water access with livestock instead of cash, which she then sells using Facebook at high rates during Muslim festivals to generate a sustainable revenue source.

What do you get when you combine the efforts of an engineering company with an energy company? In the Netherlands, you get a new type of environmentally sustainable roads.

Jane Cavarozzi, an entrepreneur and activist, started Dirty Girl coffee to “support economic development and women’s advancement in the small, depressed villages around Appalachian Ohio.” She lives in the town of Glouster and is respected for living local and working local, as opposed to being an outsider problem-solver. Though her coffee company is just one small step forward, she works closely with community groups to move economic development initiatives for the region forward.

In Mancos, Colorado, the school board voted “no” to arming school staff in the traditionally Western town. Across the United States, the question of arming teachers is being brought up as a response to the increase in school shootings.

For the Mancos community, such a vote is a surprise given the town’s gun-friendly history, but is explained by the increase in new residents.

After an initial shock to business-as-usual, some independent booksellers are trying new methods to get their products in the hands of readers. Home deliveries, online sales, and fundraising efforts are keeping some longstanding institutions afloat, at least for now.

They partner with the Denver Metro Emergency Food Network, delivering about 290,000 meals since the pandemic began. The model is working in other cities, including Seattle and San Francisco.

Teens selling water on the sweltering streets of Atlanta are typically dealt with by police officers who often crack down on "unpermitted sales of water by youth." In a new approach, city officials convened a council to offer alternatives to police action and suggested ways to promote and develop the entrepreneurial spirit in teens through a variety of programs. The council looked to a similar program in Baltimore that re-engaged windshield-washing teens in school and re-directed others to full-time jobs.

Philanthropies are funding “tough tech” startups that are developing technologies to cut greenhouse gas emissions and mitigate the effects of climate change. Since 2014, the nonprofit Prime Coalition has channeled more than $24 million from wealthy donors and foundations to 10 ventures focused on that goal. Not all of their investments, though, have paid off. Yet, some of these initial investments could lead to widespread solutions to the world’s climate crisis.
