India now possesses one of the world most advanced forest monitoring systems, capable of scanning dense forests through clouds and darkness in near real time. Yet despite this technological leap delayed institutional response and weak governance continue to undermine efforts to prevent forest degradation fires and carbon loss.
The concern has gained urgency after the operational rollout of the joint NASA ISRO satellite mission, NISAR, in late 2025. Built over more than a decade at a cost of nearly $1.5 billion, the radar satellite now scans almost every forest patch in India every 12 days generating nearly 80 terabytes of environmental data daily.
However experts warn that while India ability to detect ecological damage has dramatically improved, the systems required to respond quickly remain outdated and ineffective.
Satellite alerts are improving but forest fires continue unchecked
The gap between monitoring and intervention became evident earlier this year when parts of Odisha’s Similipal Tiger Reserve caught fire once again during February and March. Satellite systems detected thermal anomalies before field officials could identify the fires on the ground, but the response mechanisms remained largely unchanged.
Forest officials relied on manual tools such as leaf blowers and safety kits the same methods used during previous fire incidents in 2021. Odisha continues to remain among India’s most fire-prone states alongside Uttarakhand and Chhattisgarh.
Environmental experts say this reflects a deeper governance failure. India no longer suffers from a lack of environmental data. Instead, the challenge lies in converting satellite intelligence into rapid, coordinated action capable of preventing long-term ecological damage.
The issue is particularly significant because much of the destruction occurring in forests today is not outright deforestation, but gradual degradation. Selective logging, repeated low-intensity fires and small-scale encroachments often leave tree cover appearing “green” in conventional surveys while silently reducing biomass and carbon storage.
New global research exposes flaws in traditional forest assessment
A 2025 study published in Scientific Reports by researchers from the UK National Centre for Earth Observation demonstrated how advanced radar and lidar technology can reveal hidden carbon losses missed by conventional satellite imagery.
Using Japanese ALOS-2 radar systems and NASA GEDI lidar data, researchers mapped forest biomass across Africa at extremely high resolution. The study found that African forests, which had previously absorbed carbon had begun losing nearly 106 million tonnes of above ground biomass annually between 2010 and 2017.
Importantly, most of these losses were linked not to visible deforestation, but to slow forest degradation that traditional “greenness-based” monitoring systems failed to capture.
Experts say India faces a similar challenge
India’s Forest Survey reports, released every two years, primarily depend on optical satellite imagery that measures vegetation cover. Critics argue that the methodology cannot effectively distinguish between healthy primary forests, degraded forests and monoculture plantations.
As a result, forests may continue appearing stable in official records even while suffering severe ecological decline internally.
Data from international monitoring platforms indicate that India lost nearly 2.31 million hectares of tree cover between 2001 and 2024, releasing around 1.29 gigatonnes of carbon dioxide equivalent into the atmosphere. Carbon goals may remain out of reach without faster governance reforms
The issue has implications far beyond conservation. India’s updated Nationally Determined Contributions (NDCs), approved in March 2026, commit the country to creating an additional carbon sink of 3.5 to 4 billion tonnes of CO₂ equivalent through forests and tree cover by 2035.
Meeting these targets will require not just sophisticated monitoring technology but credible systems for measurement, reporting and verification (MRV) that global carbon markets increasingly demand.
While NISAR and allied satellite systems can now provide highly detailed biomass maps and track ecosystem changes almost weekly, experts say India still lacks the institutional architecture to operationalise this information.
There is currently no nationwide real time degradation alert system linked directly to enforcement agencies. Nor are local forest dependent communities, especially Gram Sabhas in states like Odisha, Jharkhand and Chhattisgarh, meaningfully integrated into forest carbon monitoring frameworks.
Conservation specialists point to Brazil’s community-led REDD+ programmes as an example where local participation and satellite verification work together to improve accountability and generate carbon revenue.
For India the challenge now is no longer technological capability, but governance readiness
Experts say the country must move beyond showcasing sophisticated satellite infrastructure and focus on building responsive institutions, faster enforcement systems and community linked forest management models. Without that shift, India risks becoming a country capable of watching ecological decline unfold in real time but still unable to stop it.
