The UN Security Council addressed an increasingly urgent issue: the environmental impact of armed conflicts. Currently, more than 2 billion people —a quarter of the world’s population— live in war-affected areas.
From Gaza to Ukraine, violence not only leaves human victims but also a deep ecological footprint. The bombs devastate crops, pollute water sources, and destroy habitats that take decades to recover.
The damage does not end when the weapons fall silent. Eroded soils, polluted rivers, and destroyed forests hinder economic and food recovery, perpetuating the cycle of poverty and displacement.
Devastated nature and collapsing ecosystems
The armed conflicts often leave a legacy of pollution, toxic waste, and biodiversity loss. The destruction of dams, burning of fields, and use of explosives affect both flora and fauna.
In Gaza, for example, the war destroyed most of the crops and contaminated freshwater and marine ecosystems. In Ukraine, the collapse of the Kakhova dam flooded thousands of hectares, altering natural habitats and displacing entire species.
These ecological catastrophes have consequences that extend for generations, worsening food and health insecurity in regions already hit by poverty and climate change.
War and climate: a dangerous relationship
Climate change exacerbates conflicts by reducing available resources, while war accelerates environmental degradation. The struggle for water, fertile land, and energy has become one of the silent drivers of global instability.
In turn, the environmental impacts of war —such as deforestation, air pollution, and soil loss— fuel global warming and hinder climate mitigation efforts.
This interaction creates a vicious cycle: conflicts destroy the environment, and environmental degradation, in turn, increases the likelihood of new confrontations.
Towards international environmental protection in times of war
The UN seeks to strengthen the legal framework that protects nature during and after conflicts. Although there is still no binding global treaty, in 2022, 27 preliminary principles were approved to promote the preservation of ecosystems in war contexts.
These norms are based on international humanitarian, environmental, and human rights law, and aim to ensure that natural resources are managed sustainably even in times of crisis.
The goal is to reduce the effects of war on the environment and facilitate ecological recovery once peace is restored.
What other environmental consequences do armed conflicts bring
Wars generate impacts that transcend the battlefield. Forest fires caused by explosions and bombings destroy entire natural reserves. Soil and water contamination by fuels, heavy metals, and munitions endanger human and animal health.
Moreover, the mass displacement of people puts pressure on fragile ecosystems, where settlements are established without adequate infrastructure. This accelerates deforestation, overexploitation of resources, and habitat loss.
Post-conflict reconstruction also has a high environmental cost: millions of tons of debris, waste, and hazardous materials require special treatment to avoid a new wave of pollution.
Benefits of rebuilding with an ecological focus
The environmental recovery after a conflict can become an opportunity for peace and resilience. Restoring ecosystems and ensuring sustainable management of natural resources help rebuild local economies and reduce dependence on humanitarian aid.
An ecological approach to reconstruction promotes food security, boosts green jobs, and improves air and water quality. Additionally, it strengthens social cohesion by offering communities a common goal: to care for the environment they share.
The UN emphasizes that investing in climate adaptation and environmental management after war not only protects the planet but also paves the way for lasting and sustainable peace.
