Scientific studies are expanding to measure the state of soils in Ukraine, now a major environmental issue. Behind the fighting, diffuse pollution is taking hold, affecting millions of hectares of farmland in a country long considered one of Europe’s breadbaskets.
In Ukraine, soils polluted by hostilities: metals and diffuse contamination
Initial analyses converge: Ukrainian farmland shows worrying pollution levels directly linked to the fighting. According to a study published in the journal Science of The Total Environment, these lands contain heavy metals, hydrocarbons, and explosive residues from bombardments and military equipment. This contamination is not limited to the surface: it penetrates deeper, permanently altering the soils’ chemical composition.
Armed conflicts cause lasting soil degradation. Repeated passages of heavy vehicles compact the soil, reducing its ability to retain water and support crops. Moreover, the microbial biodiversity, essential to soil fertility, is heavily disrupted. Consequently, the soils gradually lose their productive capacity. This pollution also has a health dimension. Contaminants in soils can be absorbed by plants and then enter the food chain. In the medium term, overall food security could be weakened.
Agricultural soil pollution has a direct impact on bread prices
And this is not an internal problem for this Eastern European country. The degradation of Ukrainian agricultural soils disrupts grain production, triggering cascading effects on international markets – this pollution also contributes to higher bread prices in Europe. It should be noted that Ukraine plays a key role in global exports of wheat and corn. When soil quality deteriorates, yields fall and some lands become temporarily unfit for cultivation. This situation heightens tensions on global supply, in a context already strained by climate and geopolitical crises.
At the same time, Ukrainian farmers face additional costs. Restoring land, soil analyses, and adapting farming practices require significant investments, often difficult to shoulder during conflict. This further weakens a sector strategic to the country’s economy.
Mapping soils and measuring heavy metal pollution
In response, scientific research is mobilizing. International teams are closely collaborating with Ukrainian institutions to assess the scale of the pollution. Field campaigns are underway to pinpoint the most affected areas and measure contamination levels. This work benefits from targeted funding. A program funded to the tune of £500,000 (about €580,000), or roughly $620,000, aims to better understand the war’s impact on farmland and to develop tailored solutions. The dual goal is to produce reliable data and to provide practical tools for farmers.
In addition, academic cooperation programs have been established. Partnerships with Ukrainian universities are training local stakeholders in soil analysis techniques and restoration strategies. This approach aims to build on-the-ground capacity in a long-term, sustainable fashion.
What solutions exist to depollute Ukraine’s agricultural soils?
While the diagnosis is worrying, solutions are emerging gradually. Researchers are focusing on depollution techniques tailored to agricultural contexts. Among them, biological approaches such as phytoremediation, which uses certain plants to absorb heavy metals from soils, show promise.
Adapting farming practices is also essential. This includes altering crop rotations, improving organic matter management, and limiting practices that could worsen contamination. These adjustments gradually restore soil fertility.
Farmer training is another key lever. University cooperation programs include training sessions dedicated to managing polluted soils. The goal is to quickly disseminate best practices and reduce health risks associated with agricultural production. Finally, precise mapping of contaminated zones helps steer decisions. Some plots may be temporarily taken out of production, while others may be farmed under certain conditions. This differentiated approach limits economic losses while protecting consumers.
