In the midst of a range of green mountains lies Nilgiris, a small district in Tamil Nadu in Southern India that is home to over 80,000 farming families. Currently the district faces three major sanitation and environmental challenges that affect agriculture: 1) chemical fertilizers have contaminated the plants, soil, and water1; 2) Nilgiris was only declared open defecation free in 2018 when the community gained full access to proper toilets; and 3) fecal sludge from the toilets has been discharged into the forest and river. 23
New innovations for impact and profit
RDO Trust, a nonprofit that has worked in Nilgiris for over 40 years, sees these challenges as an opportunity to serve the rural community by pioneering a circular economy model that combines sanitation and agriculture by using low-cost technologies. This regenerative approach focuses on increasing the efficient use of natural resources to minimize waste creation and reduce carbon emissions.
“Our innovation has been dealing with two waste streams for the production of the product, which is called the co-compost. The two waste streams are the wet waste or the biodegradable waste and the recycled fecal sludge. Put together, we have the co-compost to sell to the farmers as a business.” RDO Trust Executive Director, Rajkumar Sampath explained.
Building smallholder farmer relationships
Initially, RDO faced acceptance barriers from farmers in the district.
Nilgiris was not yet on its three-year roadmap to adopting organic farming, so farmers were still using chemical fertilizers and pesticides. Additionally, farmers had a negative perception of co-compost due to its use of human waste.
To win their customers’ hearts and share the products’ benefits, RDO spent months building trust and confidence among the farming community.
“We asked the farmers what compost they are using, and…if they knew what is in that compost. The answer was no. Nothing is transparent. [They] only know the name and don’t know much about the composition,” Rajkumar shared. “We told the farmers that we want to be transparent with them. So, we said that this compost has wet waste [and] fecal sludge, but both things are treated very well. We also took farmers to the processing unit to see the compost production, and share[d] with them the analysis report. So, the farmers were very happy to see this transparency. [Also] the price has been very negotiable or very affordable [for] farmers. Eventually, they were convinced that they could use this co-compost.”
The exchange of information and willingness to explain the product are not the only ways RDO engages the local community. The innovation is facilitated through a social enterprise that employs a group of women called “women green workers, or sanitary workers.”
A bright future for RDO’s innovation and farmers
After their past success, RDO planned to expand their business and bring their innovation to new town panchayaths and municipalities. Their plans are well underway, thanks to a $500,000 grant from the Water for Food and Energy (WE4F) during the South and Southeast Asia Regional Innovation Hub’s first Regional Call for Innovations.
RDO Trust also receives support that will help them identify suitable households for cooperative expansion and collect information on the impact of co-compost. This support not only helps RDO Trust understand their environmental and livelihood impact, but also communicate it to stakeholders. In the long term, it will help RDO Trust build supportive enabling environments and raise funds.
“In the next few years under the WE4F program, we are looking at having six new centers producing co-compost. So, in total we will have eight centers in the district,” Rajkumar said. “We are moving slow, but I think it is still a steady pace at which we are going to help increase the farmers’ income, and protect the environment.”
