Chennai Ran Out of Water — But That's Only Half the Story

Through a government funding program, several communities are working on initiatives to improve their access to clean drinking water. In India, one community formed a citizen’s group, cleaned up a local pond, and restored its natural water flow. Another initiative involved more than 1,000 women from 21 villages to build rainwater harvesting structures. These projects are seen as models for water conservation efforts as climate change exacerbates the country’s ongoing water crisis.

Thanks to years of government intervention, the city of Copenhagen has almost perfectly clean water — even better than bottled water. Denmark utilizes overflow barriers, underground water storage, and rerouted wastewater to keep their public water sources clean. Public awareness and a water tax also contribute to the city's success so that residents conserve and value their water (using only 26 gallons a day as opposed to the 80-100 gallons that Americans use).

A group of farmers in India have been trained to monitor their village’s groundwater levels to help its residents make more informed decisions about irrigation based on water availability. The farmers-turned-researchers are known as “Bhujal Jaankars” and they monitor rainfall, dam water levels, and water quality to notify residents so they can plant crops that don’t require a lot of water. While there is a lack of gender diversity in the group, they are working on developing training to include more functional literacy skills to encourage participation from others.

The San Francisco Bay area is home to a number of crucial wetlands and streams that are quickly being impacted by climate change. For nearly two decades, however, elementary teachers and their students have been playing a part in repairing the damage and revitalizing the areas through restoration and revegetation projects.

For landowners living in close to proximity to the Mississippi River, this means continuously facing the impacts of unexpected flooding. The Wetland Reserve Enhancement Program offers the farmers on these lands the opportunity to protect and restore the wetlands in order to reduce the side effects of living in flood territory.

For years, campaigns to clean Nepal's polluted Bagmati River resulted in failure. Now with police and government backing, the organization Safai Abhiyaan is in its third year, attracting hundreds of volunteers who are willing to brave the polluted waters to collect trash. The program's unique approach to organizing community volunteers has been a success, but the problem will not subside until greater perceptions about litter and water pollution are tackled.

In a science class in a local New Jersey school, students came up with a green solution to a storm water management and flooding problem in their parking lot when it rained. With help from the Cooperative Extension Water Resources Program out of Rutgers University and funding from city agencies, they were able to build planters and install concrete to absorb the runoff. The project galvanized the community, encouraging the school to expand their STEM curriculum.

Indonesian villagers were experiencing water shortages as natural springs started to dry up in part due to climate change, so they installed infiltration wells to collect and absorb rainwater. Not everyone, at first, wanted to implement the wells on their property, but by 2020, there were 320 infiltration wells in Patemon village. This water conservation project is not being implemented throughout the rest of the country.

Scientists and environmentalists are working to keep several fish species native to the Colorado River basin from going extinct. Through interventions like fish hatcheries and wetland management, some fish numbers like the ponytail and razorback sucker have rebounded. They’re now looking toward implementing their success at other parts of the river system.

Indigenous communities in Louisiana are working with scientists to restore wetland ecosystems and protect tribal mounds along the Gulf Coast through backfilling projects. Depleted oil wells and canals in the area are often abandoned, creating reservoirs of stagnant water that affects freshwater plants and animals. The group has started to identify priority canal sites to fill in and seek funding to kick off the project, which can be challenging to get.
