Mass treatment helps Uganda to eliminate trachoma

Climate change has led to shorter, more violent rainy seasons in the highlands around Lima, Peru, meaning that - even though there is theoretically enough water during the rainy season to sustain the local population, it flows downhill too quickly, leaving residents short of clean water during the dry season. Now, an organization called Condesan is helping the community to restore ancient stone canals from the seventh century that will help to store water from rainfall through the dry season and supply residents with a steady water source.

A collaboration between architectural designers and medical providers created a cholera treatment clinic in Port-au-Prince where the design of the building itself supports treatment. The building is well ventilated and filled with natural light, provides an open space for providers to see many patients and be able to respond in case of crisis, and has the ability to collect and treat water.

A new tablet, called the Feelif multimedia device, allows blind children to learn braille and geometry and play interactive learning games with their fingers. The device allows children to create drawings and write on a tablet and then feel what they've created in a 3 dimensional way.

Although commonplace in many parts of the world, Berlin has recently adopted the practice of using water fountains to cut back on plastic bottle usage. Not everyone supports this environmental push, but the mayor is hopeful they will at least catch on with tourists who are accustomed to the invention already as well as act as a resource for refilling plastic bottles rather than throwing them away.

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.

The Anacostia, which has long been one of the most polluted rivers in the country, has been given a new lease on life, thanks to cleanup efforts and a recent sewer upgrade in D.C. Since water quality has improved, there's been renewed interest in waterfront recreation and development. Now local groups are working to mitigate displacement from gentrification, with some success.

After learning that poor hygiene and sanitation practices often leads to an increase in diseases, on man in Kenya decided to install pit latrines for his community to lead by example. This practice, along with other approaches such as handwash stations, has now spread to other communities and has shown a decrease in illnesses throughout the villages.

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.

An ophthalmologist has created a smartphone application that allows not just doctors, but also non-specialists such as teachers, to conduct eye tests. The application helps those living in remote areas to access a service they otherwise may not be able to get and also allows for the few ophthalmologists who live in the area to only see the cases that are deemed necessary.

A community-led sanitation approach ended the practice of open defecation, a major cause of water pollution and stomach diseases. The program educated people to change social norms and laws requiring every household to own a toilet and punishing those who defecated in the river with a substantial fine were critical to its effectiveness. The community drove the program, with widespread adoption made easier by the benefits like fewer flies and less stomach illnesses. Low budget toilets, requiring only labor to dig a hole and resources available in the bush, were constructed so that everyone could afford it.
