The Tamsa River has undergone a marked revival in Azamgarh district of eastern Uttar Pradesh following concerted administrative action and community participation under the Namami Gange Programme (NGP). The river, an ancient tributary of the Ganga, flows through Ambedkar Nagar, Ayodhya and Azamgarh districts and an approximate 89-kilometre stretch in Azamgarh passes through 111 Gram Panchayats (GPs). The District Ganga Committee (DGC) and local stakeholders coordinated planning and implementation to address siltation, waste accumulation and encroachments. A detailed grassroots action plan prioritised desilting of shallow stretches, removal of garbage and debris from riverbanks and measurement and deoccupation of illegal encroachments. Plantation of fruit-bearing trees along available land parcels was included to support ecological restoration and provide economic value through local produce for the GPs. Officials ensured that sanitation workers and local volunteers were engaged to maintain the restored stretches. Sustained Shramdaan and awareness campaigns mobilised school children, youth, women’s self-help groups, voluntary organisations and residents to prevent dumping and promote segregation of wet and dry waste. Dustbins were installed at key locations and regular cleanliness drives focused on removal of plastic, polythene and other solid waste from ghats and banks. Convergence with the Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA) facilitated labour support and underlined the participatory model of restoration. Officials reported improvements in water quality, revival of biodiversity and enhancement of soil fertility and irrigation potential in adjacent agricultural areas as direct outcomes of the work. The initiative has also improved the cleanliness and organisation of religious and cultural activities on riverbanks, enhancing the experience for devotees. Authorities indicated that the Tamsa renewal provides a replicable model for conservation of tributaries and smaller rivers across the Ganga basin and will continue in mission mode under the NGP.
