(IPS) Soil pollution is posing a serious threat to our environment, to our sources of food and ultimately to our health. The Food and Agriculture Organization of the United Nations (FAO) warns that there is still a lack of awareness about the scale and severity of this threat.
FAO released a report titled “Soil Pollution: A Hidden Reality” at the start of a global symposium which has taken place 2-4 May, 2018 at FAO headquarters, with participation from experts and policymakers to discuss the threat of soil pollution in order to build an effective framework for a cohesive international response.
Background: What is soil pollution?
“Soil pollution refers to the presence of a chemical or substance out of place and/or present at a higher than normal concentration that has adverse effects on any non-targeted organism. Soil pollution often cannot be directly assessed or visually perceived, making it a hidden danger” states the FAO report. As a “hidden danger” right below our feet, soil pollution turns out to be underestimated affecting everyone – humans and animals.
The FAO report warns that this dangerous phenomenon should be of concern worldwide. Its consequences are not limited to the degrading of our soils: ultimately, it also poisons the food we eat, the water we drink and the air we breathe. Soil pollution significantly reduces food security, not only by reducing crop yields due to toxic levels of contaminants, but also by causing crops produced from polluted soils unsafe for consumption both for animals and humans.
The Global Symposium on Soil Pollution (GSOP18), aims to be a step to build a common platform to discuss the latest data on the status, trends and actions on soil pollution and its threatening consequences on human health, food safety and the environment.
The report prepared by FAO shows how the Sustainable Development Goals (SDGs) are deeply linked with the issue of addressing soil pollution. SDG 2 (Zero Hunger), SDG 3 (Good Wealth and Well-Being), SDG 12 (Responsible Consumption and Production) and SDG 15 (Life on Land) have all targets which have direct refernceto soil resources, particularly soil pollution and degradation in relation to food security.
Furthermore, the widespread consensus that was achieved on the Declaration on soil pollution during the UN Environment Assembly (UNEA-3, December 2017) is an obvious sign of global determination to tackle pollution and its causes, which mainly originate from human activities. Unsustainable farming practices, industrial activities and mining, untreated urban waste and other non-environmental friendly practices are amongst the main causes of soil pollution, highlights FAO’s report.
Facts and figures to note
The FAO report is an updated benchmark of scientific research on soil pollution and it can be a critical tool to identify and plug global information gaps and therefore advance a cohesive international response to soil pollution.
According to findings of the report, the current situation is of high concern. For example, the amount of chemicals produced by the European chemical industry in 2015 was 319 million tonnes. Of that, 117 million tonnes were deemed hazardous to the environment.
Global production of municipal solid waste was around 1.3 billion tonnes per year in 2012 and it is expected to rise to 2.2 billion tonnes annually by 2025. Some developing countries have notably increased their use of pesticides over the last decade. Rwanda and Ethiopia by over six times, Bangladesh by four times and Sudan by ten times.
The report also highlights that “the total number of contaminated sites is estimated at 80,000 across Australia; in China, the Chinese Environmental Protection Ministry, estimated that 16 per cent of all Chinese soils and 19 per cent of its agricultural soils are categorized as polluted”.
“In the European Economic Area and cooperating countries in the West Balkans” adding, “there are approximately 3 million potentially polluted sites”. While in the United States of America (USA) there are “more than 1,300 polluted or contaminated sites”. These facts are stunning and the international community needs to turn its urgent attention to preserve the state of our soils and to remediate polluted soils into concrete action.
The report also warns that studies which have been conducted, have largely been limited to developed economies because of the inadequacy of available information in developing countries and because of the differences in registering polluted sites across geographic regions.
This means that there are clearly massive information gaps regarding the nature and extent of soil pollution. Despite that, the limited information available, is enough for deep concern, the report adds.
