Developing world countries tend to have the lowest levels of waste water treatment. Often, the water that farmers use for irrigating crops is contaminated with contaminated pathogens. The pathogens of most concern are bacteria, and viruses, which directly affect farmers’ health, their families and most especially, their children. The great news is that there are a number of organizations working tirelessly to turn that around.

Solar water disinfection is a low-cost method of purifying water that can often be implemented with locally available materials. Unlike methods that rely on firewood, it has low impact on the environment. One organization working to improve the availability of safe drinking water in some the world’s poorest countries is WaterAid International. Operating in 26 countries, WaterAid is working to make lasting improvements to peoples’ quality of life by providing long-term sustainable access to clean water in countries such as NepalTanzania, Ghana and India. It also works to educate people about sanitation and hygiene.

Sanitation and Water for All (SWA) is a partnership that brings together national governments, donors, UN agencies, NGOs and other development partners. They work to improve sustainable access to sanitation and water supply to meet and go beyond the MDG target, In 2014, 77 countries had already met the MDG sanitation target, 29 were on track and, 79 were not on-track. This is a positive thing.
