Nearly two-thirds of global agricultural land is at risk of pesticide pollution, a study says<\/figcaption><\/figure>\n<\/div>\n<\/div>\n

A third of the planet’s agricultural land is at “high risk” of pesticide pollution from the lingering residue of chemical ingredients that can leach into water supplies and threaten biodiversity, according to research published Monday.<\/p>\n

The\u00a0use of pesticides<\/a>\u00a0has soared globally as\u00a0agricultural production<\/a>\u00a0has expanded, prompting growing fears over\u00a0environmental damage<\/a>\u00a0and calls to cut hazardous chemical use.<\/p>\n

Researchers in Australia modelled pollution risk across 168 countries with data on the usage of 92 active pesticide ingredients and found “widespread global\u00a0pesticide pollution<\/a>\u00a0risk”.<\/p>\n

They highlighted several acutely vulnerable ecosystems in South Africa, China, India, Australia and Argentina, at the nexus of high pollution risk, high water scarcity and high biodiversity.<\/p>\n

The study, published in\u00a0Nature Geoscience<\/i>, found that overall 64 percent of global\u00a0agricultural land<\/a>\u00a0\u2014approximately 24.5 million square kilometres (9.4 million sq miles)\u2014was at risk of pesticide pollution from more than one active ingredient, and 31 percent is at high risk.<\/p>\n

“It is significant because the potential pollution is widespread and some regions at risk also bear high biodiversity and suffer from water scarcity,” said lead author Fiona Tang, of the University of Sydney’s School of Civil Engineering.<\/p>\n

Tang said there were a number of factors that would contribute to a region becoming a potential contamination hotspot, including using excessive amounts of pesticides or those containing highly toxic substances.<\/p>\n

Some environmental factors may also slow the breakdown of the pesticides into non-toxic substances, like cold temperatures or low soil carbon, while heavy rainfall might also cause high levels of run-off.<\/p>\n
