The Green Gridlock: Arunachal Pradesh Holds Firm on Subansiri Project's Plantation Dilemma

Arunachal Pradesh Puts Brakes on Subansiri Hydel Project's Green Promise, Demanding Local Tree Cover

A significant snag has emerged for the ambitious Subansiri Lower Hydroelectric Project: Arunachal Pradesh is steadfastly refusing an outside-state compensatory plantation plan, insisting on reforestation within its own borders.

You know, sometimes even the grandest projects hit unexpected snags, and right now, the massive Subansiri Lower Hydroelectric Project is grappling with just such a dilemma. It turns out, the Arunachal Pradesh government is simply not budging on a crucial environmental commitment: where to plant the trees meant to offset the forest land devoured by this massive power project. They're saying a firm "no" to plans that would see these vital compensatory plantations happen anywhere but within their own state borders.

So, here’s the rub: The National Hydroelectric Power Corporation (NHPC), the folks behind this 2,000 MW behemoth, put forward a plan. They suggested carrying out the mandatory compensatory afforestation – that's planting new trees, essentially – for a significant 460 hectares of diverted forest land in states like Madhya Pradesh or Odisha. Their reasoning? They claim there isn't enough suitable "non-forest degraded land" or "open forest area" within Arunachal Pradesh itself. But Arunachal, understandably, isn't buying it. They're drawing a line in the sand, insisting that if trees are cut down for a project in Arunachal, the new ones must grow in Arunachal.

This isn't just a minor administrative spat, either; it’s the latest twist in what has already been a pretty long and eventful journey for the Subansiri project. Way back in 2005, construction kicked off, but it quickly ran into massive protests, particularly from environmental groups and local communities concerned about its impact. In 2011, things ground to a halt entirely. It took another eight years, until 2019, and a nod from the National Green Tribunal, before work could finally restart. Now, with the finish line in sight – they were hoping for commissioning around March 2024, though that's looking a bit optimistic now – this plantation issue has popped up as a fresh, albeit significant, hurdle.

From Arunachal Pradesh's perspective, their stance isn't just about state pride; it’s rooted in national guidelines. They're pointing directly to a 2018 directive from the Union Ministry of Environment, Forest and Climate Change (MoEFCC). This particular guideline, if you read it closely, pretty much mandates that compensatory afforestation should ideally take place within the same state or Union Territory where the original forest land was diverted. And, quite frankly, they’re right. It just makes sense, doesn't it, to replace what was lost, locally?

What's more, Arunachal Pradesh firmly refutes NHPC’s assertion that suitable land is scarce within its borders. "Nonsense," they might as well be saying. Officials there contend that, actually, their state is blessed with ample stretches of degraded forest land – areas perfect for bringing back to life with a fresh burst of green. It seems, then, to them, the argument for planting elsewhere just doesn’t hold water.

This whole disagreement, while seemingly focused on a plot of land and some trees, actually has far-reaching consequences. Until this compensatory afforestation plan gets a clear stamp of approval and, crucially, starts moving forward, the Subansiri project won't receive its final forest clearance. And without that, well, the full operationalization of this massive power generation effort remains in limbo, potentially pushing back its timeline even further. It’s a classic case of a critical environmental requirement holding up a major infrastructural dream, highlighting the ongoing tension between development and ecological preservation.
