From the ancient Aravalli hills battling mining pressures to the sinking islands of the Sundarbans, from drying Himalayan springs to coral-rich marine habitats and shrinking urban green spaces, some of India’s most critical ecosystems are facing unprecedented threats.
Climate change, rapid urbanisation, unsustainable resource extraction, habitat fragmentation, pollution, and biodiversity loss are pushing many of these landscapes towards ecological tipping points. Yet, amid these challenges, a handful of officers have emerged as determined defenders of nature, proving that conservation is most effective when backed by science, community participation, and long-term vision.
Across mountains, forests, coastlines, rivers, and cities, their efforts offer a glimpse of what environmental stewardship can achieve.
Holding Back the Sea
Thousands of kilometres away, another battle is unfolding where land meets the sea.
The Sundarbans, the world’s largest mangrove delta, faces an existential threat from rising sea levels, powerful cyclones, tidal erosion, and climate change. Home to nearly 4.5 million people, the region has witnessed villages disappear, embankments collapse, and agricultural lands become increasingly vulnerable.

For Jones Justin, a 2018-batch Indian Forest Service officer serving as Deputy Field Director of the Sundarbans Tiger Reserve, the challenge was clear: conventional engineering solutions alone were not enough.
Instead of relying solely on costly concrete structures, Justin helped revive a traditional technique using terracotta rings. Working with WWF-India, the Forest Department deployed thousands of locally made terracotta silt traps along vulnerable shorelines.
These simple structures slow tidal currents and trap sediment, gradually rebuilding eroded land and creating favourable conditions for mangrove regeneration. More than 10,000 such traps have already been installed across multiple locations.
What makes the initiative particularly noteworthy is its ability to generate multiple benefits simultaneously. The project strengthens shoreline stability, supports mangrove restoration, creates habitats for marine organisms, and generates livelihoods for local artisans who manufacture the rings.
By blending traditional wisdom with modern conservation science, Justin has demonstrated how low-cost, community-led interventions can improve climate resilience in one of the world’s most vulnerable coastal landscapes.
Transforming Conservation Through Communities
When Sandeep Tambe arrived in Sikkim as a young Indian Forest Service officer, he encountered a state facing multiple environmental crises.
Illegal grazing, logging, and hunting were degrading forests. High-altitude lakes were suffering from unmanaged tourism. Rural poverty remained widespread, and mountain springs were steadily drying up.
Rather than treating these issues separately, Tambe recognized that all of them were connected to local livelihoods and community participation.
His first major breakthrough came through the creation of Eco-Development Committees. These village-level institutions empowered communities to become active stakeholders in forest protection while creating alternative livelihood opportunities.
The approach proved remarkably successful. With community support, stronger enforcement, and political backing, illegal grazing and hunting declined significantly, helping restore ecological balance in many protected areas.
Tambe also introduced innovative mechanisms to protect Sikkim’s iconic lakes such as Tsomgo and Khecheopalri. Community-managed Lake Protection Committees took responsibility for sanitation, tourism management, and conservation activities, ensuring that local people directly benefited from protecting natural assets.
Later, while working in rural development, he pioneered reforms in MGNREGA implementation, promoted transparent social audits, and launched the celebrated Dhara Vikas programme.
Through scientific groundwater recharge and spring-shed management, thousands of drying springs were revived, improving water security and rural livelihoods.
Tambe’s legacy lies not only in ecological restoration but also in demonstrating that conservation succeeds when communities become owners rather than spectators.
Reviving the Himalayas’ Lifelines
Across the Himalayan state of Uttarakhand, disappearing springs had quietly become one of the region’s biggest environmental challenges.
Reduced rainfall, deforestation, changing land-use patterns, and climate change had caused springs to dry up, leaving villages dependent on water tankers and forcing many families to migrate in search of better opportunities.
As Divisional Forest Officer of Narendranagar Forest Division, Dharam Singh Meena decided to tackle the crisis at its roots.
Rather than focusing on short-term water supply measures, he adopted a scientific watershed-based approach. Collaborating with institutions such as IIT Roorkee, the National Institute of Hydrology, CEDAR, and other experts, his team conducted extensive hydrogeological mapping across the Heval river basin.
The findings guided a series of interventions including spring-shed treatment, afforestation, groundwater recharge structures, stream restoration, and riverfront management.
Community participation formed the backbone of the effort. Villagers planted nearly ten lakh native trees and contributed to restoration activities through employment generated under MGNREGA.
The impact has been substantial. Sixty-six springs and seventeen streams were revived, improving water availability for more than one lakh people across twenty-three villages.
Beyond restoring water sources, the initiative improved agricultural productivity, strengthened groundwater recharge, reduced migration, and revived local economies—showing how ecological restoration can directly improve human well-being.
Protecting a Marine Treasure
India’s Gulf of Mannar Biosphere Reserve is among the country’s most biodiverse marine ecosystems.
Its coral reefs, seagrass beds, mangroves, and coastal habitats support more than 4,200 species while sustaining the livelihoods of nearly two lakh people.
Yet increasing fishing pressure, habitat destruction, wildlife trafficking, and plastic pollution have placed this ecosystem under severe stress.
Under the leadership of Jagdish Bakan, a 2017-batch Indian Forest Service officer and Director of the Biosphere Reserve, conservation efforts took a distinctly community-centred turn.
Recognising that biodiversity protection cannot succeed without local support, Bakan established 252 Eco-Development Committees and promoted over 55 alternative livelihood opportunities to reduce dependence on fragile marine resources.
His initiatives also focused on restoring degraded habitats, including mangroves, coral reefs, and seagrass ecosystems.
Perhaps most importantly, fishermen were transformed into conservation allies. Local communities became active participants in marine wildlife rescue operations, anti-poaching efforts, and habitat monitoring.
The results were significant enough to earn Bakan UNESCO’s Michael Batisse Award 2023, making him the first Indian recipient of the prestigious honour.
His work has become a globally recognised example of how conservation and livelihood security can advance together.
Bringing Forests Back to Cities
Not all conservation battles are fought in remote forests or coastal landscapes.
Some take place in the heart of India’s rapidly expanding cities.
In Navi Mumbai, a three-acre dumping ground near Kopar Khairane had become a symbol of urban environmental decline. Covered with debris, plastic waste, and contaminated soil, the site offered little ecological value.
Determined to reclaim the space, IAS officer Abhijit Bangar, then Municipal Commissioner of the Navi Mumbai Municipal Corporation, launched an ambitious restoration initiative.
Working with Green Yatra, he adopted the Miyawaki method of afforestation and transformed the degraded land into a dense urban forest.
More than 60,000 native saplings representing over 60 species were planted after extensive soil restoration and ecological planning. Recycled water from a nearby sewage treatment plant was used for irrigation, ensuring sustainable resource use.
Within a year, the transformation was remarkable. Trees reached heights of up to 20 feet, while birds, butterflies, insects, reptiles, and mammals returned to the area.
Today, the once-abandoned dump yard functions as a biodiversity refuge, carbon sink, and urban cooling zone.
The project demonstrates how innovative urban planning can restore ecological functions even within densely populated cities.
Saving an Ancient Mountain Chain
Stretching across four states and regarded as one of the world’s oldest mountain ranges, the Aravallis act as a natural barrier against desertification, recharge groundwater, support wildlife movement, and help regulate air quality across northern India.
However, decades of mining and developmental pressures have steadily weakened this ecological shield.
Concerned by the growing threat, former Indian Forest Service officer R.P. Balwan has stepped forward to defend the range’s ecological integrity. His intervention came after a Supreme Court order limited the applicability of a sustainable mining plan to Aravalli ranges with elevations above 100 metres.
Balwan argued that such a definition fails to recognize the Aravallis as a single interconnected ecosystem. In his application before the Court, he warned that excluding valleys, foothills, and lower-elevation areas could leave nearly 90 percent of the landscape vulnerable to mining and degradation.
He has consistently maintained that hills, valleys, forests, and wildlife corridors function as one ecological unit and cannot be protected in isolation. According to him, fragmentation of the landscape could accelerate desertification, worsen pollution levels in the National Capital Region, and affect ecological stability across the Indo-Gangetic Plains.
By advocating for a science-based definition aligned with the Forest Survey of India, Balwan has reignited a national conversation on the future of the Aravallis and the importance of protecting ecosystems as complete living systems rather than disconnected fragments.
