Given the high costs of land inundation, human displacement, ecological damage, and the operation, transportation, and evaporation losses of large in-stream reservoirs, any plan to rejuvenate the Ganga must emphasize distributed water storage in the basin’s groundwater, lakes, tanks, and ponds, as well as the promotion of wetlands and forests.
The revered soil scientist Dr. Rattan Lal, an Indian-American, won the 2020 World Food Prize for inventing and mainstreaming a soil-centric approach to increase food production that restores and conserves natural resources while mitigating climate change. Over the course of his five-decade career, he has promoted innovative soil-saving techniques that have benefited the livelihoods of over 500 million smallholder farmers, improved the food and nutritional security of over two billion people, and saved hundreds of millions of hectares of natural tropical ecosystems. Dr. Lal contends that soil health is a dynamic notion that evolves with each generation, and that we must adapt our techniques to meet the changing needs. While commenting on the notification on E-flow for Ganga which recognizes the right of river to perform her ecological tasks, he indicated that in a similar sense, we need to reflect on the right of soil for protection against flood in order to mitigate soil erosion and improve soil health.
Wetland conservation, according to Mr. Ranjan (Ex-DG, NMCG), is an important component in river rejuvenation. Wetlands are separate ecosystems that are permanently or seasonally inundated by water. Floodplains and surrounding wetlands are especially important because they can directly contribute to improved river flows. The ‘Namami Gange’ mission has collaborated with a number of partners, including WWF, WII, and state wetland authorities, to produce a good inventory, ground verification, integrated management plans (IMP), and their implementation for conservation and protection. A special Namami Gange project is ongoing in Uttar Pradesh, creating IMPs of 226 wetlands within 10 kms of the Ganga spanning over 1,000km length as a one-of-a-kind endeavor to scale up wetland conservation to river and basin level .
Dr. Tripathi, reproaches the existing administration, to which he says that, in spite of forming a separate ministry, and after investing a large sum, only a little has been done, and the results are far from satisfactory. The results of Ganga cleaning are not exactly reflecting what is being claimed, and the flow of ganga is still tipping, reducing her diluting capacity, he elaborates. There are dead zones leading from industrial waste dumps that may be up to 2 kilometers long. Every year, about 700 tons of ash from the burning of around 33,000 dead corpses are thrown into the river, along with the remnants of those deceased bodies. These are some of the things he describes as impeding efforts to clean Ganga .

Pilot Projects and studies

According to the article, the Indian government initiated a pilot afforestation project along the Ganga’s banks in 2015. According to the NMCG website, this refers to a project financed by NMCG that the state forest departments of Uttarakhand, Uttar Pradesh, Bihar, Jharkhand, and West Bengal have been undertaking since 2016. The entire amount allotted was Rs 2,293 crore. However, after five years, many people consider that this endeavor is a colossal failure. Some experts have even commented that planting new trees can reduce the streamflow 70% of the time, particularly during the dry season. As per this report, Mr. Krishnaswamy stated that providing a mix of trees, grasses, and shrubs in ”suitable densities” and species composition, consistent with the river’s flow regime and the area’s temperature, will be critical to ensuring that tree-planting itself does not drain water .
For the first time, the mission received and began implementing a scientific plan for afforestation along the full length of the Ganga produced by the Forest Research Institute. This design addresses natural, urban, and agricultural riverscapes. Using it as a model, the MoEF&CC is presently applying a similar technique to 13 additional rivers around the country . However, the DG, NMCG recently informed the empowered task force (ETF) that repeated efforts have been made in the past for allocation of funds from Central CAMPA for scaling up afforestation activities under the NGP, which have not resulted in any specific results, and as a result, the comprehensive DPR developed by FRI, Dehradun has not been fully implemented. Participating in the discussions, Hon’ble Minister for Jal Shakti (MoWR) emphasized the importance of conducting a Third Part Appraisal of the Afforestation Project under the NGP to assess the impact of such large-scale intervention and going beyond simply reporting on the number of hectares and number of plants planted in the region. To which DG, NMCG responded that IIFM, Bhopal has been engaged for this sole purpose .
In light of the expired deadline of the NGP which was initially supposed to be in March 2019, was again extended to 2020 by then minister Sh. Nitin Gadkari, one report cites a study conducted by the Sankat Mochan Foundation (SMF), a Varanasi-based NGO, which revealed a significant increase in coliform bacteria and biochemical oxygen demand (BOD) over these years. SMF has developed its own laboratory to analyze Ganga water samples on a regular basis. According to these statistics, the coliform level increased from 5.2 crores in 2016 to 14.4 crores in 2019. Similarly, between January 2016 and February 2019, BOD levels increased from 46.8-54mg/l to 66-78mg/l. During the period, however, there was a minor improvement in sewage flow into the Ganga .
Nonetheless, despite all of the criticism and skepticism, there are a number of excellent developments related to the NGP’s basic aim of river rejuvenation. One such pilot case study is from Uttarakhand, where Mothugad, a rain-fed river in the Chamoli district, began to dry up over time, forcing the district administration to begin work on renewing Mothugad River in particular and cleaning rivers in general as part of the Namami Gange Project. Ms. Swati (District DM) applauded the region’s degree of public collaboration and social awareness, noting that they were able to create an Anthem for the River in their native Gadwali language. She claimed that the effort had a direct and indirect impact on 80,000 people. In terms of the project’s implementation, according to NMCG, harvesting structures were built and plantation was carried out with the support of locals, all while utilizing already available money from MNREGA and CAMPA, making it cost-effective. GIS mapping and tracking for all actions were intended for transparency, and the project was reported to be extremely scalable and practical with the deployment of geo-tagging and drone surveillance .
Another success story is of establishment of Bio Gas (CNG) Generation plant from 18 MLD Jagjeetpur STP at Haridwar. It started with Uttarakhand Jal Sansthan (UJS) recommendation for generating biogas (Bio CNG) by mandating relevant improvements in the digestor and building an Upgrade to the plant in PPP (Public-Private partnership) mode on a revenue sharing basis to address the problem of sludge disposal created at the STP plant. The NMCG supplied funds for the STP’s foundation upgrades, while the DST provided Rs. 431 lakhs in funding through its Technology Development Board for the processing unit’s technology installation. This project was said to help a number of government projects, including Namami Gange, Atmnirbhar Bharat, Swadeshi, Swachta, and others .
In a study published in 2021, Mr. Singh, collected data from field visits, household surveys, and focus group discussions (FGDs) on the ancient practice of flood recession farming (FRF). FRF refers to farmers using moisture and nutrient rich soil of the floodplains for growing crops after water levels recede and harvest them before flooding in the river. The study concludes that true potentials of FRF can only be assessed through comprehensive research about its different aspects and mainstreaming this practice in policy-making for sustainable food production .
Yet, in another very interesting and recent study, Mr. Dey who is currently a research affiliate with Nature Conservation Foundation, presented a new challenge which has hurdled as a side-effect of the push to the water ways economic model (Arth Ganga). He says that “The Ganga, as we know, already experiences an immense load in terms of motorized vessel traffic,”. The most obvious fear is that any increase in vessel traffic could result in more harm than good to the Gangetic Dolphins. Not only will the number of vessels traversing the river rise, but they will largely be on a regular schedule, resulting in a more chronic noise environment than a vessel that passes by only once. Study concludes that maintaining the ecological flows (E-Flows), downscaling of vessel traffic, and propeller modifications to reduce cavitation noise, could help mitigate noise impacts on Ganga River dolphins .
