With a mobile application, Nigerians can report and fight social injustice

The Office of Neighborhood Safety in Richmond, CA took a radical new approach to urban violence by creating mechanisms to financially stabilize perpetrators of violent acts in crime-ridden neighborhoods - essentially paying people not to kill. They have been dramatically successful at weening violent criminals off the destructive behavior by using a comprehensive approach that includes using solid data, employing mentors with similar backgrounds to the criminals, and monetary incentives.

Across the country, hospitals are embracing intensive intervention programs to help victims of violence — including those who have criminal histories — after they have been brought in for treatment of injuries. Such programs can help prevent retaliation, reduce the chance a patient will be violently injured again, and put people on track for success.

The Centre for the Prevention of Radicalization Leading to Violence in Quebec has expanded rapidly, becoming a model for programs around the world. What sets it apart from projects in Europe and the United States is that it confronts extremism of all stripes — not just Islamist — and focuses on behavior that signals the risk of violence, not just radical ideas, only involving law enforcement as a last resort.

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.

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.

Since Camden began addressing its high homicide rate in 2012 with closer collaboration with the community and stricter rules on the use of force, both murders and complaints about police have fallen dramatically. As part of what is considered some of the most extensive police reforms in the country, the city put more police on the streets. That had both good outcomes (interactions outside of crises) and bad (a troubling increase in low-level arrests). But, when many cities’ police-brutality protests in 2020 turned violent, Camden’s did not.

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.

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.
