When the Vietnam Conflict lastly ended on April 30, 1975, it left behind a panorama scarred with environmental harm. Huge stretches of coastal mangroves, as soon as housing wealthy shares of fish and birds, lay in ruins. Forests that had boasted a whole bunch of species have been lowered to dried-out fragments, overgrown with invasive grasses.
The time period “ecocide” had been coined within the late Sixties to explain the U.S. navy’s use of herbicides like Agent Orange and incendiary weapons like napalm to battle guerrilla forces that used jungles and marshes for canopy.
Fifty years later, Vietnam’s degraded ecosystems and dioxin-contaminated soils and waters nonetheless mirror the long-term ecological penalties of the conflict. Efforts to revive these broken landscapes and even to evaluate the long-term hurt have been restricted.
As an environmental scientist and anthropologist who has labored in Vietnam for the reason that Nineties, I discover the neglect and sluggish restoration efforts deeply troubling. Though the conflict spurred new worldwide treaties aimed toward defending the atmosphere throughout wartime, these efforts did not compel post-war restoration for Vietnam. Present conflicts in Ukraine and the Center East present these legal guidelines and treaties nonetheless aren’t efficient.
Agent Orange and daisy cutters
The U.S. first despatched floor troops to Vietnam in March 1965 to help South Vietnam towards revolutionary forces and North Vietnamese troops, however the conflict had been occurring for years earlier than then. To battle an elusive enemy working clandestinely at evening and from hideouts deep in swamps and jungles, the U.S. navy turned to environmental modification applied sciences.
Probably the most well-known of those was Operation Ranch Hand, which sprayed no less than 19 million gallons (75 million liters) of herbicides over roughly 6.4 million acres (2.6 million hectares), of South Vietnam. The chemical substances fell on forests, and likewise on rivers, rice paddies and villages, exposing civilians and troops. Greater than half of that spraying concerned the dioxin-contaminated defoliant Agent Orange.

Herbicides have been used to strip the leaf cowl from forests, enhance visibility alongside transportation routes and destroy crops suspected of supplying guerrilla forces.
Scientific organizations additionally initiated research inside Vietnam throughout the conflict, discovering widespread destruction of mangroves, financial losses of rubber and timber plantations, and hurt to lakes and waterways.

In 1969, proof linked a chemical in Agent Orange, 2,4,5-T, to start defects and stillbirths in mice as a result of it contained TCDD, a very dangerous dioxin. That led to a ban on home use and suspension of Agent Orange use by the navy in April 1970, with the final mission flown in early 1971.
Incendiary weapons and the clearing of forests additionally ravaged wealthy ecosystems in Vietnam.
The U.S. Forest Service examined large-scale incineration of jungles by igniting barrels of gas oil dropped from planes. Significantly feared by civilians was using napalm bombs, with greater than 400,000 tons of the thickened petroleum used throughout the conflict. After these infernos, invasive grasses typically took over in hardened, infertile soils.
Fires from napalm and different incendiary weapons cleared stretches of forest, in some instances scorching the soil so badly that nothing would regrow.

“Rome Plows,” large bulldozers with an armor-fortified slicing blade, may clear 1,000 acres a day. Monumental concussive bombs, often called “daisy cutters”, flattened forests and set off shock waves killing every little thing inside a 3,000-foot (900-meter) radius, right down to earthworms within the soil.
The U.S. additionally engaged in climate modification by way of Mission Popeye, a secret program from 1967 to 1972 that seeded clouds with silver iodide to extend the monsoon season in an try to chop the circulation of fighters and provides coming down the Ho Chi Minh Path from North Vietnam. Congress finally handed a bipartisan decision in 1973 urging a global treaty to ban using climate modification as a weapon of conflict. That treaty got here into impact in 1978.
The U.S. navy contended that every one these ways have been operationally profitable as a commerce of timber for American lives.
Regardless of Congress’ considerations, there was little scrutiny of the environmental impacts of U.S. navy operations and applied sciences. Analysis websites have been onerous to entry, and there was no common environmental monitoring.
Restoration efforts have been sluggish
After the autumn of Saigon to North Vietnamese troops on April 30, 1975, the U.S. imposed a commerce and financial embargo on all of Vietnam, leaving the nation each war-damaged and cash-strapped.
Vietnamese scientists informed me they cobbled collectively small-scale research. One discovered a dramatic drop in fowl and mammal range in forests. Within the A Lưới valley of central Vietnam, 80% of forests subjected to herbicides had not recovered by the early Eighties. Biologists discovered solely 24 fowl and 5 mammal species in these areas, far beneath regular in unsprayed forests.
Solely a handful of ecosystem restoration initiatives have been tried, hampered by shoestring budgets. Probably the most notable started in 1978, when foresters started hand-replanting mangroves on the mouth of the Saigon River in Cần Giờ forest, an space that had been utterly denuded.

In inland areas, widespread tree-planting packages within the late Eighties and Nineties lastly took root, however they targeted on planting unique timber like acacia, which didn’t restore the unique range of the pure forests.
Chemical cleanup remains to be underway
For years, the U.S. additionally denied accountability for Agent Orange cleanup, regardless of the popularity of dioxin-associated diseases amongst U.S. veterans and testing that exposed persevering with dioxin publicity amongst doubtlessly tens of hundreds of Vietnamese.
The primary remediation settlement between the 2 nations solely occurred in 2006, after persistent advocacy by veterans, scientists and nongovernmental organizations led Congress to acceptable US$3 million for the remediation of the Da Nang airport.
That challenge, accomplished in 2018, handled 150,000 cubic meters of dioxin-laden soil at an eventual price of over $115 million, paid principally by the U.S. Company for Worldwide Improvement, or USAID. The cleanup required lakes to be drained and contaminated soil, which had seeped greater than 9 toes (3 meters) deeper than anticipated, to be piled and heated to interrupt down the dioxin molecules.

One other main scorching spot is the closely contaminated Biên Hoà airbase, the place native residents proceed to ingest excessive ranges of dioxin by way of fish, rooster and geese.
Agent Orange barrels have been saved on the base, which leaked giant quantities of the toxin into soil and water, the place it continues to build up in animal tissue because it strikes up the meals chain. Remediation started in 2019; nevertheless, additional work is in danger with the Trump administration’s close to elimination of USAID, leaving it unclear if there shall be any American specialists in Vietnam in command of administering this complicated challenge.
Legal guidelines to stop future ‘ecocide’ are difficult
Whereas Agent Orange’s well being results have understandably drawn scrutiny, its long-term ecological penalties haven’t been effectively studied.
Present-day scientists have much more choices than these 50 years in the past, together with satellite tv for pc imagery, which is being utilized in Ukraine to establish fires, flooding and air pollution. Nonetheless, these instruments can’t change on-the-ground monitoring, which frequently is restricted or harmful throughout wartime.
The authorized state of affairs is equally complicated.
In 1977, the Geneva Conventions governing conduct throughout wartime have been revised to ban “widespread, long term, and severe damage to the natural environment.” A 1980 protocol restricted incendiary weapons. But oil fires set by Iraq throughout the Gulf Conflict in 1991, and up to date environmental harm within the Gaza Strip, Ukraine and Syria point out the bounds of counting on treaties when there aren’t any robust mechanisms to make sure compliance.
Remediation work to take away dioxin contamination was simply getting began on the former Biên Hoà Air Base in Vietnam when USAID’s workers was dismantled in 2025.

A global marketing campaign at the moment underway requires an modification to the Rome Statute of the Worldwide Felony Courtroom so as to add ecocide as a fifth prosecutable crime alongside genocide, crimes towards humanity, conflict crimes and aggression.
Some nations have adopted their very own ecocide legal guidelines. Vietnam was the primary to legally state in its penal code that “Ecocide, destroying the natural environment, whether committed in time of peace or war, constitutes a crime against humanity.” But the legislation has resulted in no prosecutions, regardless of a number of giant air pollution instances.
Each Russia and Ukraine even have ecocide legal guidelines, however these haven’t prevented hurt or held anybody accountable for harm throughout the ongoing battle.
Classes for the longer term
The Vietnam Conflict is a reminder that failure to handle ecological penalties, each throughout conflict and after, could have long-term results. What stays in brief provide is the political will to make sure that these impacts are neither ignored nor repeated.
