In Search of Solution to Detroit's Water Shutoffs, Could Philly Hold the Answer?

Billions of people around the world lack access to safe sanitation, causing disease and deaths. In Ecuador a foundation developed a cheap, dry, composting toilet for poor rural families.

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.

Mitigating homelessness on Los Angeles' infamous "Skid Row" comprises myriad obstacles. But a collaboration between city officials, a USC architecture class project, and the Skid Row Housing Trust has responded with a multi-pronged solution in "pod-style" housing units. They have composed a cost-effective pre-fab design technology that eases their transportation, on-site construction and visual imposition on a neighborhood, while the pods' zoning classification as "congregant housing" minimizes the risk for local opposition to homeless support services on claims of structural or aesthetic noncompliance.

Uganda’s education ministry requires all schools to have incinerators to burn used sanitary pads. Lack of funding limits schools’ ability to comply. Even when incinerators exist, girls don’t necessarily use them. Educating both girls and boys about menstruation reduces stigma and increases the likelihood that girls feel comfortable enough to collect pads instead of throwing them in pit latrines.

Atlanta has seen a decline in rates of people experiencing homelessness from 2008-2018, a trend that is particularly meaningful as other cities contend with stubbornly high numbers. Part of the solution? A new source of more flexible and consistent funding allowing non-profits to provide the assistance needed and help get people into permanent supportive housing.

The simple addition of adding handles to bathroom stalls in the Rohingya refugee camps in Bangladesh has helped the camps' pregnant women regain a sense of empowerment and dignity. Providing support and balance, the design of these latrines have benefited the elderly in the camps as well.

Clarke County School District in Georgia has 21 public schools that all offer free meals to students, regardless of their financial needs. This is facilitated through a federally-funded program, so even though poverty rates are high in the area, local residents are not footing the bill. While there are still some challenges implementing the program, in general it is received well and allows students to focus on their work and well-being instead of being distracted by hunger.

The Hounslow council sent £20 vouchers to every household to help the local economy recover from the COVID-19 pandemic. Households had about two months to spend the voucher, which could purchase products or services at a range of businesses from cafes and cinemas to retailers and laundromats. Retailers can use an app to scan the vouchers and eventually redeem them for payments.

Amidst water scarcity and increased waterborne diseases, community members are using sand dams, an innovative water management system, to conserve rainwater for daily use. Sand dams offer extended water storage capabilities, lasting up to a year, ensuring community members have consistent access to clean water for farming, cooking and general hygiene. There are currently six sand dams in the community serving 600 households.

Several pilot studies point to the viability of desalination projects being an effective option for farmers in certain fresh-water-scarce regions.
