Los retos de las ‘apps' antidesperdicio más allá de rescatar comida

Health communication systems designed for rural, developing countries -- where hospitals are often understaffed and transportation is inadequate -- are being adapted to improve care in U.S. cities.

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.

The Do-Good Auto Coalition in northern New Jersey is recruiting car dealerships and automakers to help shuttle supplies and food to people experiencing economic hardships during the COVID-19 pandemic. The closing of restaurants, schools, and other businesses has created a disconnect in the food supply chain, with fresh produce stuck on farms with no easy way to get it to consumers. While there’s no quick fix to reduce food waste, the organization is hopeful they can bridge the gap between farmers and people who can’t meet their basic needs.

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.

Contact tracing apps have received a lot of attention since the onset of the coronavirus pandemic, but researchers caution they should be used in conjunction with other tactics and not be relied on to help on their own. However, an early study has indicated that even when only fifteen percent of the population downloads a contact tracing app, infection rates are reduced by eight percent and deaths are reduced by six percent.

A community organization in Indiana called Cultivate "rescues" food from local caterers, hospitals, casinos, and businesses to then be packaged into take-home meals for students at Woodland Elementary School that come from food-insecure homes. Cultivate is in its second year of existence, has three staff and 400 volunteers, and hopes to expand beyond their pilot program to reach all 21 schools in the district.

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.

To help prevent food waste, Coldhubs provides solar-powered cold stations in local markets where farmers can store produce and perishable goods until they are ready to sell them. The organization has served more than 5,000 small farmers so far.

An app called Visis translates text and photos to speech to help Nigerian people with visual impairments to live their lives independently.

To reduce landfill use and greenhouse gas emissions while feeding those in need, New York’s food donation program requires big businesses to donate edible food to places like food banks instead of throwing it out.
