Treating sewage with plants
Neknampur lake serves as a fitting example of how low cost but effective natural techniques can be used to clean city lakes that are choking with pollutants. Posted on 17 Apr, 2018 04:56 PM

A radical new method is fast emerging as an effective and sustainable solution to increasing pollution in urban lakes. Called floating treatment wetlands (FTW), they are artificial islands with plants that stay afloat on the lake. The plants clean the lake through hydroponics system, resulting in a cleaner, beautiful lake and an improved habitat for creatures that depend on it.

Tourism increases black carbon in air
A study finds an increased concentration of black carbon in Gangotri region during tourist seasons. Posted on 16 Apr, 2018 03:25 PM

In a significant input for the growing debate on global climate change, a study by researchers at the Dehradun-based Wadia Institute of Himalayan Geology (WIHG) has found that there is a remarkable increase in the concentration of black carbon in the atmosphere near the pilgrim town of Gangotri in Uttarakhand during the two annual tourist seasons of April to June and during September and Octobe

Tackling fluorosis by following Nalgonda's lead
Engaging with the fluorosis problem in Nalgonda gave the FKAN a chance to understand the problem and apply the solutions nationally. Posted on 15 Apr, 2018 04:21 PM

Fluorosis continues to be a regional issue in Telangana to this day, even decades after the first cases were discovered in Nalgonda in 1937. More than three lakh people in the district are affected with skeletal and dental fluorosis, a stigma that has stuck for generations.

Saving Jhabua’s children from fluorosis
INREM Foundation’s work helped develop protocols on designing proactive action on safe water and nutrition to help mitigate fluorosis in Jhabua. Posted on 13 Apr, 2018 09:03 PM

In 2010, nine-year-old Kailash from Miyati village, Jhabua developed symptoms of skeletal fluorosis. Fluorosis, which affects millions of people in India, is a health issue caused due to high fluoride content in drinking water. Skeletal fluorosis is marked by deformed bones.

Nutrition garden developed in Jhabua for sustainable nutrition and resistance from fluorosis among villagers.
Power play chokes Korba
The video tells the story of residents of Korba and nearby villages who are affected by the fly ash from power plants which makes Korba the fifth critically polluted area in the country. Posted on 11 Apr, 2018 02:05 PM

Korba in Chhattisgarh is an industrial area which has a significant number of coal mines and thermal power plants. Fly ash is a byproduct of the thermal power plants and has become a significant problem for the residents of Korba now.

Nanomaterial from seaweed can clean toxic water
A team of scientists have synthesised graphene-iron sulfide nanocomposite from abundantly found seaweed Ulva fasciata through direct pyrolysis technique. Posted on 08 Apr, 2018 09:02 PM

Treatment of wastewater containing industrial dyes and toxic heavy metals is a major environmental problem as available treatment techniques are not very efficient and environment-friendly. Now a team of Indian scientists has developed a nanomaterial drawn from seaweed for effective treatment of toxic wastewater without using any chemicals.
