Description: Keralam protects what ecological wealth remains and quietly degrades the rest. Restoring it is not idealism but infrastructure with a measurable return. From a series asking what Keralam 2040 would have to be.

---

Someone asked me recently why Keralam needs elephants and tigers when Europe is prosperous without them. The question states the development-first argument plainly: get prosperous first, and sort out the ecology later, or not at all.

Europe destroyed most of its large wild fauna over centuries, banked the prosperity, and is now spending some of that accumulated wealth trying to put back what its great-grandparents removed. Wolves, strictly protected under the 1979 Bern Convention, have spread back across the continent and now occur in all 34 countries and regions the EU monitors, with the monitored European population about 23,000 in the 2023 assessment.[^3] That protection has since been loosened. In March 2025 the wolf was downgraded under the Bern Convention, and in June 2025 the EU moved it to a lower tier of its Habitats Directive, a reminder that even a rich continent's buy-back can be revised.[^3] The lynx is recovering too, helped by translocations and new reintroduction projects.[^3] The EU's Nature Restoration Law, in force since August 2024, sets an EU-wide target of restoration measures on at least 20% of the Union's land and sea areas by 2030, and on every ecosystem that needs it by 2050. It was contested all the way: the European Parliament passed it by 329 votes to 275.[^1] The bill is real money: the EU's LIFE programme runs to €5.4 billion for 2021 to 2027, of which about €2.1 billion is set aside for nature and biodiversity.[^2]

Europe is not a model of prosperous ecology. It is a cautionary tale with a good balance sheet. Keralam still holds, intact, much of what Europe is now paying to rebuild. The question is whether it keeps it.

### Holding Is Not Rebuilding

Keralam already does the first half of this work. It conserves. The state has a forest department, wildlife sanctuaries, and protected areas covering 6.4% of its geographical area, a little over a fifth of its recorded forest land. Satellite mapping, which counts every patch of tree canopy of a hectare or more, puts the state's forest cover at about 54%.[^5] Periyar, Silent Valley, the Wayanad sanctuaries: these mostly hold. Conservation, the holding action, works.

Restoration is the other half, and Keralam does not yet have it at any serious scale. Conservation asks how much of what remains we can protect. Restoration asks how much of what we have already degraded we can rebuild. The gap between the two is a failure of ambition, not of intent.

> Keralam built the institutions to hold a forest. It has not yet built the ones to rebuild one.

A word on what restoration here does not mean. It is not a plea to return to a pristine, pre-human Keralam. There is no going back, and the reason is demographic, not sentimental. The land-use decisions that did the damage, the eucalyptus from the 1950s, the teak plantations from the 1840s, the wetland drainage spread across the whole century, were made when Keralam held a fraction of the people it holds today. We are more people now, on the same land, while expecting more from it. An argument that ignores that is romanticism, and will rightly be dismissed as such. The frame is regenerative rather than preservationist. The question is not how to get back to what was there before people. It is how to build forward to an ecological estate that flourishes alongside the population and economy Keralam has. Every target below is a forward design choice under present constraints, not a rollback.

Four things are worth rebuilding, and each of them has a matching thing the state could do about it. Start with the objection underneath the original question, which is that elephants and tigers are a luxury, an amenity a developing state can defer. The ecology says otherwise. They are keystone species, which means their presence or absence reorganises the entire system around them.

### The Shola

Start with the eucalyptus, wattle, and pine that were planted across the high ranges and the Nilgiri Biosphere from the 1950s onward as industrial plantations. As recently as 2024 the government allowed its own forest development corporation to plant more eucalyptus for its finances, before freezing the order after protests. The monocultures remain. What they replaced was shola grassland, a mosaic of montane grass and stunted evergreen forest that is home to threatened species found nowhere but these mountain-tops,[^7] and, more usefully for this argument, a water tower. Shola grassland holds the monsoon in a sponge and releases it slowly into the rivers through the dry months. Replace it with bluegum and you do not just lose an ecosystem. You lose dry-season flow downstream: a paired-catchment study in the Nilgiris found that converting grassland to bluegum cut annual water yield by 16 per cent in the first rotation and 25 per cent in the second, with low flows falling further still.[^6] There is no reliable state-wide figure for how much shola Keralam has lost. Across the Shola Sky Islands of the southern Western Ghats, which span Keralam, Tamil Nadu and Karnataka, remote sensing puts the montane grassland lost to exotic trees, both planted and spreading on their own, at roughly 340 square kilometres between 1973 and 2017.[^7] The encouraging part is that removal works: in Pampadum Shola, the Forest Department cleared around 475 hectares of wattle between 2020 and 2024, and Keralam adopted a State Eco-Restoration Policy in 2021 that prioritises pulling these exotics off high-altitude land.[^8] The scale of the problem still dwarfs the scale of the response.

> The eucalyptus went in as an industrial crop. As late as 2024 the state allowed more of it to be planted. The shola has not come back.

Teak complicates the picture usefully. Teak is native to India, including the moist deciduous forests of Keralam's lower slopes where Nilambur sits, though not to the wet evergreen forest higher up the Ghats. The systematic monocultures here are a colonial inheritance: the first organised plantations went in at Nilambur in the 1840s, to replace the teak that naval timber contracts had stripped from Malabar.[^9] Much of what people take for Keralam's ancient forest is, in part, a nineteenth-century timber estate. That does not weaken the case for restoration. It makes it selective. Teak stays, because the wildlife that now depends on it has no alternative and the economic value is real, but the monoculture can be diversified over time, native canopy and understory threaded back in. The shola case is different: the eucalyptus there is not economically necessary to the state, it actively harms the water system, and it is replaceable. Not every plantation carries the same restoration logic, and a doctrine that treats them alike will be wrong about one of them.

What to do about it is within Keralam's own hands. The state can direct its Forest Research Institute to put a rupee value on what shola restoration is worth in dry-season river flow, which is the number that would make the economic case for eucalyptus removal at scale. It can spend its compensatory-afforestation money on shola restoration. And it can make the fund do what it exists for. The Comptroller and Auditor General's 2013 audit of compensatory afforestation found that in Keralam, according to the state's own records, "no afforestation was done on non forest land and degraded forest land", the land set aside to receive it, and that 0.96 crore rupees of the CAMPA money had gone on the "purchase of vehicles".[^20] The money has to reach the land.

### The Wetlands

Keralam's wetlands have been drained and filled for aquaculture, paddy, and construction for decades. The trend is clearest at Vembanad, the great backwater lake behind Kochi and Alappuzha. Benchmarked against Survey of India mapping, its water spread fell from 290.85 square kilometres in 1917 to 213.28 by 1990, a loss of just over a quarter, most of it reclaimed for polders on the southern sector and to enlarge Willingdon Island.[^10] Three of these systems, Vembanad-Kol, Ashtamudi, and Sasthamkotta, carry Ramsar designation as internationally important, which makes their decline a public statement about what the state values.[^10] The official post-disaster assessment judged that, at that rainfall, flooding along the backwaters was unavoidable. It also found that the limited capacity of Vembanad Lake and the Thottappally Spillway worsened the flooding in Kuttanad, and that silting had left Kuttanad's drainage canals far below their original capacity. It put the damage and loss at about ₹26,700 crore.[^11] Some unknown share of that was a bill for reclamation and drainage decisions made decades earlier. To hold what is left, the state must do more than print protection labels. It must reverse the worst reclamations, reopen blocked channels, restore polder hydrology, buy development rights on the worst-placed parcels, and enforce a no-net-loss rule so that every new conversion is offset in function, not on paper. It must give its wetland authority real restoration targets with five-year milestones, where today it has labels.

*Figure: The lake lost just over a quarter of its water spread across the twentieth century, and three-quarters of that loss was finished before 1970. The often-quoted 365 square kilometres is an older estimate of the backwaters' extent up to 1834, not comparable with the 1917 water spread measured here.*

### The Corridors

Keralam's protected areas are becoming islands. The land between them, where the roads and plantations and settlements are, has broken the routes wildlife once used to move, breed, and follow the seasons. The data is less clear than it should be. Of twenty-four elephant corridors that experts had drawn in the Nilgiri Biosphere, a connectivity model found that only eleven followed routes better than chance, and the expert teams agreed with each other on just two.[^12] One Keralam corridor, Peria to Pannippad, is only about four hundred metres wide, with private land and a road at its bottleneck, though the 2023 national survey records elephants using it more, not less.[^13] I suspect many of the elephant-in-the-village stories that fill Keralam's news are a corridor problem: animals moving along historical routes that development has narrowed.

*Figure: Roughly half the corridors the experts mapped do not hold up when connectivity is modelled, and the experts agreed with each other on only two.*

Elephants are ecosystem engineers in the technical sense.[^14] They open the canopy and let light reach the floor, they break limbs that become deadwood habitat, they dig at mineral seeps that other animals then use. Most consequentially, they may be the main disperser left for some of Keralam's largest-fruited forest trees. If they go, those trees may regenerate less, and the composition of the forest may drift, slowly and without anyone deciding it, over the decades that follow. For Asian elephants the evidence, as of the 2011 review, was fragmentary.[^15]

> Keralam's elephants are not decorative. They are the architects of the forest. Remove them and the forest may change composition, slowly, over the decades that follow.

The state can write the most fragmented corridors into its land-use plans, starting with the worst few in the Nilgiri Biosphere. But a corridor on a plan is only a corridor if something stops the edge from closing on it, and that is a decision someone has to defend at a budget meeting. It has two halves, and they only work as a pair. The first half is a line.

The first half is a line. There has to be a firm, mapped boundary for where cultivation and settlement are permitted on land that abuts forest. Today that boundary is soft and quietly receding. Cultivation, plantation, and settlement creep into the forest edge and into the corridor land between reserves, which is precisely what narrows those corridors. A soft boundary means the conflict zone grows every year, and every new hectare of forest-edge planting manufactures human-wildlife conflict that did not exist the year before. The line is not anti-farmer. It is the precondition that makes the rest fair.

### The Human-Animal Edge

Tigers sit at the top of the same system. Tiger numbers track the numbers of their prey closely, so tigers are bound tightly to the herbivores beneath them.[^16] Whether tigers in turn hold browsing and rooting low enough to protect forest regeneration is plausible but not yet well shown. The best-known case of a predator reshaping a landscape is the Yellowstone wolf, and even that is disputed: a twenty-year experiment there found that the streamside willows had not recovered after the predators returned.[^17] The tigers themselves do not respect the question's framing, or the state's borders. Keralam's own estimate is 213 tigers, part of one connected Western Ghats population estimated at 1,087 in 2022.[^18] That a tiger cannot be assigned to a single state is exactly the point of an essay about corridors.

The second half is the bill. Inside the permitted zone, where conflict still happens, the state pays for animal-caused damage in full and on time. It does not answer crop loss by licensing farmers to eliminate the animal they identify as the cause. Recent policy has moved the other way. In May 2022 the state empowered local bodies to shoot wild boars threatening crops, life and property, and it has asked the Centre more than once to declare the animal vermin under the Wildlife (Protection) Act, which the Centre has so far declined to do.[^4] For wild boar, the direction of travel hands the animal to the local body's gun. Extended to every conflict species, the same logic would make an elephant or a tiger the individual farmer's problem to solve with a gun or a live wire. That drift is understandable and it is wrong, because it trades a permanent, shared, irreplaceable asset for a temporary, private loss that money can cover.

Keeping elephants and tigers alive is a common need, so the cost of keeping them alive is properly a common cost. The farmer at the forest edge did not choose to be the one who absorbs the price of the state's biodiversity. Asking that farmer to either swallow the loss in silence or kill the animal is asking one person to pay for something everyone owns. Full and prompt compensation is just the public paying for the public asset it has decided to keep. That reframes the whole question of crop-damage compensation. It is not welfare and it is not appeasement. It is the carrying cost of the ecological estate, and it should be budgeted and defended as exactly that.

The line and the bill need each other. Compensation without a line is unbounded: if farming keeps advancing into the edge, claims rise without limit until the scheme collapses and takes public patience for wildlife down with it. A line without compensation is unjust: it freezes the edge farmer inside a conflict zone with no recourse. Only together are they stable. Draw the line, and inside it pay every claim in full. That is a system a farmer can live with and a treasury can sustain.

Today's compensation is a floor, not a ceiling. The Forest Department has proposed setting aside about ₹15 crore a year for crop-damage compensation, a figure based on past claims and the rate revision it expected, and even that understates the real loss, because its divisions could not release all claims for want of funds and, until 2025, the rates had gone years without revision.[^19] The 2024 declaration of human-wildlife conflict as a State Special Disaster, and the revised compensation rates that followed in 2025, move in the right direction.[^19] It is incomplete without the line.

Two honest cautions, because the proposal fails without them. The first is equity. A line drawn at the forest edge falls on smallholders and forest-dwelling communities, many of them tribal, whose tenure is already insecure under a weakly implemented Forest Rights Act. The line cannot be an eviction order. It has to come with secure tenure, and where a critical corridor parcel genuinely must be cleared, with the kind of fair, consent-based buyback already done at small scale in Keralam, as on the Thirunelli to Kudrakote corridor, where a Wildlife Trust of India project run with the state government bought about twenty-five acres from thirty-seven families who relocated with their prior consent, and the land then went to the Forest Department.[^22] The line is a planning instrument, not a notice to quit.

The second caution is capture, and it is the one that quietly inverts schemes like this. Compensation flows to whoever knows the scheme exists and can position themselves to claim it. Left unconditioned, that means the tribal smallholder who has farmed the edge for generations, and does not know the scheme exists or cannot file the paperwork, gets nothing, while the well-resourced farmer reads the rules, buys approved land next to the forest precisely because it is a conflict zone, plants the most raidable crop, and farms the compensation. The carrying cost of the wildlife becomes a subsidy for speculative land-buying by the comfortable, and the conflict zone expands instead of settling, because the incentive now points toward the edge. Two conditions prevent it. Eligibility is frozen at the line, by tenure and by date: only cultivators with established tenure or recognised forest rights as of the cutoff can claim, and land bought or cleared inside the band afterward carries no compensation right, which kills the incentive to move in for the payout. And the scheme has to reach people actively, through gram-sabha enrolment and assisted claims in Malayalam and, where needed, in the relevant Adivasi languages, not through a portal that rewards whoever is most fluent in forms. Closing that information gap is part of the mechanism. Without these two conditions the whole proposal is not merely incomplete but regressive.

### What Needs Delhi

Some of the work genuinely needs Delhi. The Forest Rights Act needs the tenure security its current implementation does not deliver, both for justice and because secure communities are often the most effective stewards of corridor land. And the Nilgiri Biosphere Reserve, India's first biosphere reserve, is administered under a central programme whose budget Keralam does not set.

### The Restoration Compact

Call it a Keralam Ecological Restoration Compact, running 2027 to 2040, long enough to outlive more than one government and matched to the horizon the rest of this series uses. Four mandates, each with a first act that shows whether the thing is serious.

| Mandate | First proof of seriousness |
| --- | --- |
| Restore high-range water systems | Map the priority shola-to-plantation conversion zones and fund a five-year removal and regeneration programme |
| Reconnect wildlife landscapes | Legally identify priority corridor parcels, with voluntary purchase, tenure security, and no-new-encroachment rules |
| Rebuild wetland capacity | Set area, hydrological-function and flood-buffer targets for Vembanad-Kol and Kuttanad |
| Socialise conflict costs fairly | Full, time-bound compensation inside a mapped eligibility band, with assisted gram-sabha claims and transparent public reporting |

The first proofs matter more than the mandates. Each one is a map or a target, which is to say a public number that someone who was not in the room can check the following year. If the first year produces neither, the compact is not real.

### The Story No One Has Told

Few, if any, tropical states have yet shown that it is possible to build a knowledge-intensive, research-capable, builder-led economy while restoring its ecological base instead of spending it down. The usual tropical arc runs the other way: destroy the ecology, build the economy, then try to buy the ecology back. That is the European story.

Keralam has the institutions, the civic culture, and the intact natural estate to try the harder version. If the rest of this series is right, that the state's future runs through precision industry, research depth, and patient builder capital rather than low-cost manufacturing sprawl, then that future is ecologically compatible in a way the sprawl path never was. The restoration argument sits inside the economic one: for Keralam specifically, building a serious economy and rebuilding an ecological estate are far more compatible than the conventional development story assumes.

> Few tropical states, if any, have built a knowledge economy and left their ecological base larger than they found it. Keralam still has the chance to be the demonstration.

The estate does not end at the forest boundary, which is where the next essay begins. Kochi and Thiruvananthapuram sit on the edge of one of the planet's significant biodiversity hotspots. Singapore raised its green cover from about 36% in 1986 to close to 50% by 2010, not despite its development but as a consequence of taking the city seriously as something to be designed.[^21] A city that ignores the estate it sits in will consume it. A city that builds on it becomes somewhere people with a choice want to live, which is the only durable advantage a tropical city has left to win.
