Rajendra Singh
Rajendra Singh (born 1959) is an Indian environmentalist and water conservationist, widely recognized as the "Waterman of India" for spearheading community-driven revival of groundwater and rivers in Rajasthan's semi-arid regions through the construction of traditional earthen check dams called johads.[1]
As founder of the non-governmental organization Tarun Bharat Sangh, Singh initiated water harvesting efforts in the Alwar district in the early 1980s, shifting from his initial background in Ayurvedic medicine after local communities prioritized water scarcity over health services.[1] His approach emphasizes decentralized rainwater management to recharge aquifers, which has restored perennial flow to five rivers—including the Arvari—and provided water security to over 1,000 villages, while also enhancing forest cover and biodiversity, such as the return of antelopes and leopards.[1][2]
Singh's achievements include building more than 8,600 johads and related structures, demonstrating the efficacy of indigenous techniques in combating desertification and flood risks without reliance on large-scale infrastructure.[1] He has received the 2015 Stockholm Water Prize—often termed the "Nobel Prize for water"—for these innovations in rural water restoration, as well as the 2001 Ramon Magsaysay Award for community leadership.[1][2] Despite early opposition, including legal challenges and bans from authorities over unauthorized constructions in protected areas like Sariska Tiger Reserve, Singh's work has prevailed through grassroots mobilization and advocacy against activities such as illegal mining that exacerbate water depletion.[3][4] His model underscores the causal links between localized recharge, ecosystem regeneration, and sustainable human dependence on natural hydrology, influencing water policy discussions globally.[1]
