Challenges
Ukraine currently faces a systemic environmental crisis as the growing impacts of climate change converge with ongoing anthropogenic pressures and the devastating ecological consequences of the war.
This triple pressure places unprecedented stress on natural ecosystems, with some of the most acute vulnerabilities emerging in the water sector. Rising temperatures and changing precipitation patterns are already intensifying climate risks, contributing to droughts, ecosystem degradation, and biodiversity loss. These trends threaten agricultural production, livelihoods, infrastructure, and ecosystem services essential for the country’s long-term development and wellbeing. The impacts are particularly pronounced in southern Ukraine and along the Black Sea coast, where droughts, coastal erosion, and extreme weather increasingly affect agricultural landscapes, fisheries, and human settlements.
The resilience of Ukraine’s ecosystems is further undermined by conflict-related destruction. According to assessments by environmental organizations, up to one-third of Ukraine’s territory has been affected by war-related environmental damage, including contamination, fires, and ecosystem disturbance. The war has caused widespread pollution from damaged industrial facilities, oil depots, and military activities, while attacks on water infrastructure have disrupted hydrological systems across several regions. By 2024, hundreds of water infrastructure facilities - including dams, pumping stations, and water supply systems - had been damaged or destroyed, significantly affecting water supply, irrigation systems, and aquatic ecosystems.
The destruction of the Kakhovka Dam in June 2023 triggered one of the largest environmental disasters in Europe in recent decades. The collapse of the dam released approximately 14–16 km³ of water and drained most of the 2,155 km² Kakhovka Reservoir, dramatically changing the established over the years hydrological regime of the lower Dnipro River and exposing large areas of former reservoir bed. The event caused severe ecological disruption and the loss or degradation of extensive wetland habitats, floodplain ecosystems, and aquatic biodiversity across the region. Flooding downstream inundated more than 500 km² of land, damaging settlements, and ecosystems in the lower Dnipro basin, the Dnipro–Bug estuary, and the north-western Black Sea coast.

Drainage, degradation and contamination of the wetlands including coastal zones reduce the ability of the communities to manage water resources sustainably. As wetlands degrade and landscapes are affected by military activity, the ecosystem services typically provided by wetlands - including drinking water, water retention, filtration, groundwater recharge, and flood regulation - are significantly weakened. The degradation of these functions directly reduces Ukraine’s adaptive capacity to climate change at a time when hydrological stability is critically important.
These challenges are compounded by a long history of unsustainable land use, including intensive agriculture and extensive wetland drainage, which has reduced the landscape’s natural capacity to support small rivers, retain water and regulate local climates. While Ukraine established a strategic framework through the Strategy of Environmental Security and Climate Change Adaptation of Ukraine until 2030, significant gaps remain between national policy commitments and local implementation. At present, urgent humanitarian needs and post-war recovery priorities often overshadow long-term environmental adaptation measures, leaving local authorities with limited resources, funding, and technical capacity to strengthen coastal protection and water resilience.

Addressing these interconnected crises requires a fundamental shift toward integrating climate adaptation across sectors and governance levels. Restoring and protecting healthy ecosystems can provide cost-effective solutions, including Ecosystem-based Adaptation (EbA), that enhance resilience to climate impacts. Measures such as the restoration of the wetlands both freshwater and marine, dune systems of the coastal zone can help buffer communities from climate hazards while supporting sustainable development and post-war recovery. By strengthening natural water regulation and coastal protection functions, these ecosystems reduce vulnerability to extreme events and improve long-term water security. In this context, investing in nature-based resilience in the Black Sea region is not only an environmental priority but a critical step toward ensuring the security, stability, and prosperity of Ukrainian society in a changing climate.
