  • Safe Drinking Water Systems

    Access to clean water and sanitation in India continues to be inadequate, resulting in poor health outcomes. Despite longstanding efforts by various levels of government to improve the access and affordability of safe drinking water, only 40% of Indians have access to piped water in their homes. Clean water is directly associated with adequate nutrition, as intestinal inflammation and infection due to drinking water contaminated with worms, parasites, viruses, and bacteria can lead to partial or complete malabsorption of essential nutrients and calories, in addition to life-threatening illnesses and dehydration.

    Sustainable, Low-Cost Water Treatment Systems

    TCI partnered with AguaClara in 2014 to provide clean drinking water technology for villages in India. AquaClara installed proprietary technology developed at Cornell University that was previously implemented with great success in Latin America.

    The technology includes a filtration unit for removing suspended matter and a chemical dosing unit for removing fecal contamination, making it safe for drinking and cooking. Solar-powered pumps move the water from lowland wells to an elevated tank in the village and then into homes, all without using electricity or fossil fuels.

    With assistance from Indian non-governmental organization PRADAN, four water treatment centers were established in Jharkhand, providing drinking water to 2,000 people. Following the success of the project in Jharkhand, AguaClara worked with the development organization Gram Vikas to bring its water treatment systems to villages in the eastern state of Odisha, where it built systems in three villages in Odisha, serving about 460 people in total.

    Supporting Research

    In addition to providing clean water to residents in Jharkhand, TCI’s partnership with AguaClara supported important research related to water, sanitation, and hygiene. The projects in Odisha and Jharkhand provided evidence of how innovative, low-cost technologies can address the problem of poor access to clean water.

    In many households that lack piped water, family members—usually women and young girls—must fetch water from sources far from home. TCI studies in Jharkhand have revealed that households with piped water save an average of nearly 60 minutes per day on water collection, compared to households without them. The women in those homes increase the time spent in their primary occupation by 20% per day. Apart from being healthier, access to clean water in the home frees female family members to live more productive lives.

    About AguaClara

    A multidisciplinary program at Cornell University, AguaClara is dedicated to creating reliable, low-cost solutions to global water problems. In India and around the world, AguaClara designs plants that are gravity-powered, electricity-free, and scalable to fit the needs and size of any community.

    AguaClara’s governance model is based on community ownership, democratic governance, and technology that is specifically designed for ease of operation and to encourage pride in ownership. They build implementation partner capacity and encourage the formation of a network of implementation partners that share best practices for sustainable implementation.

  • Sfurti: Market-Based Flour Fortification

    In the fight against malnutrition, fortified staples like flour can help ensure that people consume critical micronutrients, like iron. Yet, in many areas of India, smallholder farmers do not purchase flour at the market, opting instead to grow their own grains and bring them to local millers for processing. To address micronutrient deficiency among these communities, TCI spearheaded the Sustainable Flour Fortification Initiative, or Sfurti, providing an easy-to-use, home-based method for fortification.

    The project was implemented by the Women’s Federation of Self-Help Groups—Shree Surbhi Swasahay Federation, with assistance from TCI and partner organizations BAIF Development Research Foundation, Sight and Life, the Tata Institute of Social Sciences, and Maharaja Sayajirao University.

    A Dually Burdened Society

    Micronutrient malnutrition—especially iron deficiency anemia (IDA)—is a severe public health problem for the Indian population. Anemia affects over 80 percent of children below the age of three, 58 percent of expectant mothers, 50 percent of non-pregnant and non-lactating women, and over 56 percent of adolescent girls, with IDA accounting for over 60 percent of anemia cases.

    In pregnant women, iron depletion can cause low birth weight in newborns, as well as complications caused by intrauterine growth restriction and preterm delivery. In children, low iron can lead to impaired cognitive function and delayed physical growth, as well as an overall reduced future working capacity. IDA is responsible for 24 percent of maternal mortality in India, and another 50 percent of maternal mortality has been indirectly associated with anemia. This has catastrophic consequences for future generations and can eventually lead to a “dually burdened society,” with both mothers and children suffering from anemia. The economic implications of IDA in India are also severe, accounting for 5 percent of GDP loss.

    National surveys have shown that, except for staples, the consumption of other nutritionally dense commodities, such as pulses, milk, fruits, and vegetables, fall far below the recommended dietary allowance. With meat consumption among the lowest worldwide, IDA thrives in India. Current government initiatives to control anemia are focused on providing iron and folic acid pills; however, consumer compliance is low. Therefore, TCI made it a top priority to address IDA through fortification.

    A Unique Approach

    Initiated in 2016, the objective of the Sfurti project was to improve the nutritional status of tribal communities through a sustainably managed program run by women’s collectives. Sfurti powder—containing iron, folic acid, and vitamins A and B12—was sold in 15 villages in Gujarat’s Tapi district. The Sfurti approach was unique in that it applied market-based principles, such as demand generation, social marketing, small enterprise development, and consumer purchases, to create a self-sustained model for flour fortification.

    The initiative was implemented in three stages:

      • In the first stage, Sfurti powder sachets were sold door-to-door by women from the self-help groups, known as Sfurti Bens or Sfurti sisters, who also raised awareness of the importance of micronutrients. During stage one, 69 percent of the households demonstrated a willingness to purchase the powder sachets, and 25 percent bought them regularly.
      • In the second stage, the Sfurti sisters limited their role in five of the 15 villages to raising awareness only, with Sfurti sold only at millers, instead of door-to-door. During this stage, 62 percent of households demonstrated a willingness to purchase the powder sachets, and 49 percent bought them regularly, twice the number of regularly consuming households in the first stage.
      • For the third stage, TCI and its partners took a step back and the self-help groups assumed all responsibility for selling the sachets, with their profits funding the initiative. Only regularly consuming households from the second stage were targeted, 62 percent of which were regularly consumed in the third stage. In all, 79 percent of the sachets were sold during this stage.

    Sfurti Success

    Sfurti proved to be a great success, with an adoption rate of 70 percent in the villages in which the project was implemented, and has been instrumental in raising awareness of micronutrient deficiencies and creating demand for fortified food.

    The full experience of Sfurti shows that a self-sustainable, nutrition-oriented fortification product is possible, and with the inclusion of local communities and their acceptance of the product, it can be a successful means of promoting nutrition and providing access to essential micronutrients in such communities.
