Get There Fast or Safe? A Crowdsourced Map Gives You the Option

To address the food insecurity problem among its low-income students, Columbia University launched Swipes, a meal sharing app in which students with a surplus of “meal swipes” could donate them to students in need. But when that app struggled to function and roll out properly, Columbia looked downtown to New York University, where student Jon Chin launched a similarly purposed but more effectively designed app, Share Meals. So far, the app has enabled over a thousand meal donations, and is hoping to work with Columbia to share its code and expand its donor services.

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.

The World Health Organization estimates that $200 billion worth of productivity is lost every year due to untreated poor eyesight. Several organizations, such as EYElliance and Aravind Eye Hospital, are working to combat this problem by administering free vision tests and helping people who need glasses get them at an affordable rate.

Though homelessness is an entrenched and complex problem, small solutions can make a difference in the daily life of homeless individuals. Lockers for overnight cell phone storage in a homeless shelter in Chicago are significant: people can wake up with a sense of security, knowing their phones will be available to help find jobs or stay in touch with loved ones. This is part of the Chicago Youth Storage Initiative, which as since funded 755 storage unites at homeless shelters across Chicago.

LGBTQ asylum seekers face a unique set of problems coming to the United States, often from places where gender expression and sexuality are strictly regulated. Four organizations across the US, Mexico, and Canada are filling this unique niche. For example, AsylumConnect created an app of resources on how to apply for asylum and a catalogue of LGBTQ-friendly services and organizations in the US for them to learn about. All four aim to validate LGBTQ asylum seekers and keep them safe.

Crime-tracking mobile apps give millions of Brazilians crowdsourced data on urban violence, alerting people to dangerous places and filling gaps in government data on shootings, robberies, and other risks. But apps such as Fogo Cruzado (“Crossfire”) and Onde Tem Tiroteio (“Where There's a Shooting”) offer statistically crude glimpses of crime, distorted by media and racial biases that one expert blames for myths about the risks people actually face.

An initiative on the Moscow metro system has posters on the train featuring cats and dogs that are looking for a home. Known as the “Tails and Paws” train, these animals come from 13 animal shelters in the city and riders can use their phone to scan the poster to learn more about the animals up for adoption. “It’s about forming a new culture of responsible attitude to animals,” says one of the workers at a shelter.

Advance Peace mentors young people at risk of committing or suffering gun violence, guiding them through a "life map" process to exit street life and set goals for a safer, healthier future. The program, which started in Richmond and has expanded to other cities in California and beyond, contributed to a 22% decrease in gun homicides and assaults in an 18-month period. The decrease was 39% in the first targeted neighborhood. Mentoring includes linking youth to cognitive behavioral therapy, jobs, and field trips to expand their experiences. When they meet certain goals, they get paid a "life map allowance."

Violent clashes between farmers and cattle herders that have claimed thousands of lives have largely ceased in Otukpo, thanks to a peacekeeping process that resolves disputes and is based on a shared recognition of two groups' humanity. The process imposed rules in an otherwise unruly system in which Fulani herders' open-grazing cattle destroyed crops, leading to violence. Negotiated leases and dispute-resolution mechanisms, governed through monthly meetings, have resulted in only one death since 2018, while surrounding areas continue to suffer many casualties.

Two insurance companies, Discovery and Dialdirect, implemented a smartphone app for drivers to report potholes in their city. The companies then fill the potholes and brand them with their logos.
