Not all heroes wear capes. Some quit their high-paying jobs as software developers in Dubai to return to their nation and revive 142 waterbodies. That is the story of Thanjavur-born Nimal Raghavan who, in the last five years, has done incredible work in water conservation, harvesting, rejuvenation, restoration of water bodies, water crisis management, water planning, and sewage treatment. Nimal’s life was sailing smoothly as a well-paid tech employee in the lavish city of Dubai. However, in November 2018, when he returned for a holiday to his hometown in Tamil Nadu, his perspective towards life wholly altered and he found a new purpose to strive towards.

During his vacation, he saw the fallout of his hometown just after Cyclone Gaja had wreaked havoc, leaving devastation in its wake. The cyclone had caused tremendous damage to the banks of the Kaveri Delta, leaving 45 people dead, and damaging over one lakh homes in its wake. Witnessing the aftermath firsthand, Nimal realized that his land and community were on the brink of ruin. He couldn't bear the thought of abandoning his ancestral land, which was once fertile and thriving. With unwavering determination, he made the courageous decision to quit his job and embark on a mission to revive his hometown's lost glory.

Nimal was confronted with the stark reality that Nadiyam Village, where he was born and raised, was one of the 90 villages destroyed by the cyclone. Generations of farmers were abandoning their ancestral lands, seeking employment in cities as agriculture became an increasingly uncertain livelihood. Recognizing the urgency of the situation, Nimal rallied a team of like-minded volunteers and launched an ambitious plan.

The first step was relief activities to provide immediate aid to those affected by the cyclone. Nimal spearheaded a social media campaign called #BounceBackDelta, offering essential supplies such as clothes, groceries, and financial assistance. Inspired by his work, a group of young residents from Nadiyam launched another campaign, #DeltaSaplingChallenge, to restore the lost trees of the region. These initial efforts paved the way for the larger-scale projects that lay ahead.

Nimal's crusade led him to the realization that water scarcity was a pressing issue throughout the Kaveri Delta region. With a profound understanding of the vital role that water bodies play in agriculture and livelihoods, he embarked on the ambitious task of rejuvenating Peravurani Lake, one of the largest in the area. The restoration of the lake was no easy feat, requiring meticulous planning, execution, and, most importantly, financial resources. Undeterred, Nimal and his team embarked on a fundraising journey, relying on the support of villagers and well-wishers who recognized the significance of their mission. Through their efforts, they raised more than Rs 32 lakh and managed to revive the great lake.

"The locals are involved in every stage. If we get the extractors, they volunteer to drive or fund the fuel. The youth take part in desilting, rebuilding, and all other activities. And once they have put in so much effort in restoring a water body, they automatically take care of its maintenance."

The restoration of the Peravurani Lake became a turning point in Nimal's journey. Not only did it provide a source of irrigation for over 6,000 acres of agricultural land, but it also served as a catalyst for further endeavors. Buoyed by the success, Nimal and his team went on to plant 25,000 saplings across the Kaveri Delta region, breathing life back into the once lush landscape.

After the initial success, Nimal's vision extended far beyond his hometown. He decide to expand his horizons and became actively involved in several organizations, collaborating with the likes of Kadaimadai Area Integrated Farmers Association (KAIFA), BIOTASOIL Foundation, Exnora International, Oor Koodi Oorani Kaappom, Nam Thamirabarani, and Mega Foundation. All of these organizations shared a common goal: the restoration and conservation of water bodies in Tamil Nadu and Maharashtra.

Together, they implemented a range of projects, encompassing water body restoration, Miyawaki method plantation, mangrove forests plantation, rainwater harvesting, and water treatment. The impact of their work reverberated across the regions, benefiting over 40 lakh people. Fresh drinking water became accessible, agricultural lands thrived, and livelihoods were restored. Moreover, the restored ecosystems supported species diversity, fostering a harmonious coexistence between humans and nature.
