It was a monumental catastrophe. The dynamiting of the Kakhovka dam on Ukraine’s Dnieper River simply earlier than daybreak on June 6 final yr quickly emptied Europe’s largest hydroelectric reservoir. Some 14 million acre-feet of water hurtled downstream for greater than 100 miles to the ocean. Round 80 villages had been flooded, greater than 100 folks died, and greater than 40 nature reserves had been engulfed. Within the Black Sea, the flood delivered a flush of business toxins, land mines, agricultural chemical compounds, sediment, and freshwater that killed fish and unleashed swarms of algae alongside the coast.
Ukraine’s president, Volodymyr Zelensky, referred to as it the “largest man-made environmental catastrophe in Europe in a long time” — for the reason that meltdown on the nation’s Chernobyl nuclear plant in 1986. Inside days, his authorities pledged to rebuild the dam.
However now the ecological penalties of this struggle crime — extensively presumed to be perpetrated by the dam’s Russian occupiers — are being seen in a distinct gentle. The mattress of the previous reservoir is quickly rewilding, with intensive thickets of native willow bushes rising. The nation’s ecologists are calling for plans for a brand new dam to be dropped, in favor of nurturing the ecological renewal. And so they argue that a few of Ukraine’s short-term wartime environmental catastrophes — on rivers, in forests, and throughout the nation’s treasured steppe grasslands — might be was long-term ecological good points.
After the struggle, Ukraine might safe its inadvertent ecological good points and be certain that reconstruction places the surroundings at its coronary heart.
“Warfare-wilding” can profit a rustic nonetheless chained to Soviet-era infrastructure, they are saying. After the struggle ends — which Zelensky stated throughout a go to to the U.S. in September may very well be “nearer… than we predict” — Ukraine might safe its inadvertent ecological good points and be certain that reconstruction places the surroundings at its coronary heart.
There isn’t any doubt that the breaching of the Kakhovka dam 16 months in the past was a disaster for folks residing downstream. Many ecosystems had been badly broken. The query now’s whether or not and the way nature will recuperate. At the very least within the 155-mile lengths of the drained reservoir, the prognosis is remarkably optimistic.
Ecologists initially warned that the sediments uncovered on the reservoir’s mattress would both flip to abandon and unleash mud storms laced with poisonous detritus, or else be invaded by alien species. Neither has occurred, in keeping with Anna Kuzemko, a botanist on the M.G. Kholodny Institute of Botany in Kyiv, who has made three discipline journeys to the reservoir mattress, throughout certainly one of which she was shelled by Russian mortars. The river has resumed its movement down outdated channels. Sturgeon have made it upstream to outdated spawning grounds close to the dam. Nourished by wealthy sediment, native willows have grown throughout the reservoir ground, with reed beds fringing water programs.
Throughout her most up-to-date go to, in Could, Kuzemko discovered that the brand new willow bushes had reached a mean peak of three meters. “We had been amazed. They’re rising by a centimeter every day,” she says. “At a global symposium of vegetation science in September, we concluded that the younger forest on the backside of the previous reservoir is now the most important floodplain forest in Europe.”
The scenario downstream is much less clear. The river beneath the dam web site is on the struggle’s entrance line, with Ukraine’s forces on the west financial institution and Russia occupying the east financial institution. The poisonous floodwaters right here quickly abated, however discipline journeys to take a look at their longer-term influence on ecosystems are presently inconceivable. Even so, because the preliminary harm recedes, “downstream floodplains are more likely to restore shortly, as they’re tailored to flooding,” says Eugene Simonov, a freshwater ecologist and founding father of the activist group Ukraine Warfare Environmental Penalties Work Group (UWEC).
In any case, native ecologists are sufficiently enthusiastic in regards to the rewilding of the intensive reservoir mattress that they need the newly liberated river to stay free. It’s “a novel probability to study in regards to the self-restoration capabilities of a significant European river,” says Simonov, who’s presently finding out on the College of New South Wales in Australia. He anticipates the everlasting return of what, earlier than Soviet engineers arrived within the Nineteen Fifties, was often known as the Velykyi Luh, or Nice Meadow, a area of steppe grassland and swamp beforehand prized for its archaeological stays and Cossack historical past, in addition to its ecology.
“Ukraine has an opportunity to revive its pure and historic heritage,” says a conservationist. “We should not waste this opportunity.”
The restoration of the Velykyi Luh can be “the most important freshwater restoration venture ever carried out in Europe,” says Oleksii Vasyliuk, head of the Ukraine Nature Conservation Group, which works to establish and set up protected areas throughout the nation. “Ukraine has an opportunity to revive its pure and historic heritage,” says Kuzemko. “We should not waste this opportunity.”
The good points from eschewing a brand new dam can be financial and political, as a lot as ecological, the ecologists argue. Within the Soviet period, which led to 1991, Ukraine was a bastion for constructing inefficient infrastructure that took a heavy toll on nature. Engineers put in a cascade of six hydroelectric dams on the Dnieper, Europe’s fourth longest river. The final and largest of them, the Kakhovka dam, was constructed on a floodplain, with a lot of its reservoir usually just a few toes deep.
Kakhovka took 830 sq. miles of flooded land to offer simply 357 megawatts of producing capability. That’s greater than thrice the land take for America’s Hoover Dam, to ship lower than a fifth of the ability. Simonov calculates that, slightly than rebuilding this “Soviet monster,” the identical vitality capability may very well be delivered by putting in photo voltaic panels throughout fewer than 10 sq. miles, little greater than 1 p.c of the realm flooded by the unique dam.

An additional purpose for Ukraine to not rebuild massive dams is that they’d be susceptible to future sabotage. By approving an assist package deal offering the nation with small vitality techniques, together with solar energy, Germany’s minister for financial cooperation and growth, Svenja Schulze, stated in September that her authorities was supporting “a decentralized energy provide infrastructure, as Russia will then not be capable of destroy it so simply.”
The battle in Ukraine has added a brand new time period to the environmental vocabulary: war-wilding. It was coined by British educational Jasper Humphreys, who research the influence of armed battle on nature on the Division of Warfare Research in Kings School London. He says it got here to him at the beginning of the Russian invasion in February 2022, when Ukraine halted the advance on Kyiv of lots of of tanks by breaking the Kozarovychi dam on the Irpin River. Moreover saving the nation’s capital, the inundation of some 6,000 acres of farmland downstream restored the river’s pure floodplain.
Now, just like the Kakhovka dam, the destiny of the Kozarovichy dam and the reborn Irpin floodplain dangle within the stability. Irpin metropolis authorities wish to rebuild the outdated Soviet construction, redrain the floodplain, and revive prewar plans for a large new housing growth there. However Volodymyr Boreyko, director of the Kyiv Environmental and Cultural Middle, has obtained sturdy assist for his name for the Irpin to be declared a “River Hero” of the battle, and saved pure, with beavers swimming its size and water buffalo grazing the floodplain.
Ecologists argue that if Ukraine prioritizes nature in its reconstruction plans, that can assist the nation’s software to hitch the EU.
Whereas its wrecked hydroelectric dams have attracted essentially the most headlines, Ukraine’s forests have additionally been within the entrance line of the struggle. They supply much-needed cowl in opposition to drone surveillance. With a lot of the combating taking place in and round them, they’re additionally susceptible to fires ignited by munitions. However they’ll additionally profit from war-wilding.
UWEC’s scientists estimate {that a} quarter-million acres have burned through the battle. That sounds unhealthy, however in keeping with Stanislav Viter, a forest ecologist on the Nationwide Academy of Sciences of Ukraine, the losses are “considerably smaller than these ensuing from logging and varied fires in peacetime.” In reality, the absence of loggers has meant that “some areas of frontline forests… are more and more paying homage to protected areas,” he says.
The forest war-wilding might proceed lengthy after the struggle is over, in keeping with Valentyna Meshkova, head of Ukrainian authorities’s Laboratory for Forest Safety. Many forests on the entrance line are actually dotted with minefields that would take a long time to clear. Mines are unhealthy information for giant forest animals comparable to elk. However they maintain away people, preserving habitat for a lot of smaller mammals, invertebrates, birds, and vegetation.

She likens the potential ecological advantages of the minefields to the large-scale regeneration of forests within the radioactive exclusion zone created in 1986 across the web site of the Chernobyl nuclear catastrophe within the far north of the nation. Within the absence of human exercise, pure regeneration has elevated forest cowl there by virtually 50 p.c. With greater than two-thirds of the exclusion zone now tree-covered, it has been designated a nature reserve, Europe’s third largest.
No one is aware of when the struggle will finish, and whether or not it should end in Ukraine holding on to all its former territories. However plans for reconstruction are being laid, and lots of the nation’s ecologists argue that if these plans put nature first, that shall be a beneficial credential within the nation’s software to hitch the European Union.
The EU is dedicated to reaching large ecological restoration within the coming a long time, however has not but labored out how or the place. As Vasyliuk notes, “the one place in Europe the place we will see large-scale restoration of nature is the a part of Ukraine which has suffered from army motion.” With many areas more likely to stay off-limits for many years after the struggle due to mines or munitions contamination, he says Ukraine might let nature ship environmental good points on a scale that “till now had appeared fairly distant and unrealistic.”
A number of of Ukraine’s steppe grasslands, together with the nation’s oldest protected space, are presently occupied by the Russian army.
However that is removed from a given. Whereas lots of the nation’s forests may very well be winners within the aftermath of the struggle, there’s rising concern that the large ecological losers may very well be the nation’s treasured unfenced steppe grasslands.
Ukraine has a lot of Europe’s final surviving such steppe landscapes. They’re residence to a 3rd of the nation’s endangered species, together with the much-loved, endemic sandy blind mole-rat. A number of of those areas are presently occupied by Russian army, together with the nation’s oldest protected space, the 128 square-mile Askania-Nova biosphere reserve on the east financial institution of the Dnieper River. Russian forces have dug intensive fortifications there and ignited massive fires.
Fireplace is a pure phenomenon in steppe areas, says Viktor Shapoval, the exiled director of the reserve. So, he hopes that restoration might be swift. However arguably an even bigger concern is that, even because the struggle continues, Ukraine’s foresters are planting bushes on these wealthy steppe grasslands to make up for misplaced business forests within the struggle zone. Viter says virtually 27,000 acres had been planted within the 22 months previous to the tip of 2023. He fears that, with minefields leaving many forests out of bounds for the foreseeable future, the cessation of hostilities will solely speed up the foresters’ annexation of steppe ecosystems.
The stakes are excessive for the ecological way forward for Europe’s second largest nation, after Russia. From its revived river floodplains to the mined forests of the jap struggle zone and its prized however perilously under-protected steppes, “the potential for war-wilding is large,” says Humphreys. However a lot might go flawed. When the artillery lastly falls silent, and the drones go residence, the nation will face a alternative — whether or not to construct again outdated Soviet infrastructure and stick with it as earlier than, or to turn out to be a beacon for a greener and extra sustainable Europe.
