Metals and metalloids are ubiquitous in soils, originating from bedrock and from human activities and infrastructure. These compounds can be toxic to humans and other organisms, and their soil distribution and concentrations at global scale are not well known. Hou et al. analyzed data from more than 1000 regional studies to identify areas of metal toxicity and explore drivers of these trends. They estimate that 14 to 17% of cropland exceeds agricultural thresholds for at least one toxic metal.

A new groundbreaking German study proves that pesticides spread much further from the field than previously believed. A team of scientists led by Professor Dr. Carsten Brühl tested topsoil, vegetation, streams and puddles from 78 locations over a 180 km stretch, from remote areas in the UNESCO forests on the mountain ranges to the farmland in the Upper Rhine area. The research team detected a total of 63 pesticides. Almost all measurement sites were contaminated. Residues were found in 97% of the soil and vegetation samples, often in complex mixtures of several active ingredients. This cocktail of pesticides is especially problematic because interactions can occur and effects can be amplified. The worrying results are consistent with previous smaller-scale studies in the South Tirol area in Italy. Large scale and prolonged pesticide use is a major factor in the sharp decline in populations of insects and other organisms essential for farming, as highlighted in our biodiversity campaign. The researchers see pe

Depleted soil leads to reduced yields, forcing farmers to rely on fertilizers that raise food production costs, consumer prices.

Food supply expert paints grim global picture hunger 05.23.2022 By Arvin Donley NEW YORK, NEW YORK, US — Global wheat inventories currently stand at about 10 weeks of global consumption, a food supply expert said during a special meeting of the United Nations Security Council on May 19. Sara Menker, chief executive officer of Gro Intelligence, an organization that gathers and analyzes global food and agricultural data, said she disputes official government agency estimates that put global wheat inventories at 33% of annual consumption, countering inventories are closer to 20%. “It is important to note that the lowest grain inventory levels the world has ever seen are now occurring while access to fertilizers is highly constrained, and drought in wheat growing regions around the world is the most extreme it’s been in over 20 years,” Menker said. “Similar inventory concerns also apply to corn and other grains. Government estimates are not adding up.” Menker told the security council that while much of the blame

Microplastics are deposited in river floodplains and carried down to deeper levels, according to a study published in the journal Science of the Total Environment. Local topography, frequency of floods, and soil characteristics can affect the amount of plastic particles that are deposited and potentially carried into deeper soil.

The massive and growing ‘forever chemicals’ scandal in Belgium marks the culmination and possible endpoint of the endless growth logic, not to mention the privatising of profit and the socialising of costs. This was reflected in the leaked secret settlement, reached in 2018, between a Flemish government-owned company (Lantis) and a mega-multinational (3M), which leaves the taxpayers footing the bill, currently estimated at €63 million, for just a small part of the enormous PFOS pollution that seeped into the soil and water around the 3M plant in Zwijndrecht.

Soils provide 95% of all food but are damaged by industrial, farming, mining and urban pollution. Soils are also the largest active store of carbon, after the oceans, and therefore crucial in fighting the climate crisis. But the report said industrial pollution, mining, farming and poor waste management are poisoning soils, with the “polluter pays” principle absent in many countries.

Agricultural pesticide use and its associated environmental harms is widespread throughout much of the world. Efforts to mitigate this harm have largely been focused on reducing pesticide contamination of the water and air, as runoff and pesticide drift are the most significant sources of offsite pesticide movement. Yet pesticide contamination of the soil can also result in environmental harm.

Il y a six ans, nous avions commenté sur ce même blog que, parmi tous les carburants dérivés du pétrole, le diesel était celui qui verrait probablement sa production baisser en 1er. La raison de la réduction de la production de diesel avant l’essence, par exemple, était due à la baisse de la production de pétrole brut classique depuis 2005 et au poids croissant des pétroles dits "non conventionnelles", mauvais substituts qui ne conviennent pas toujours à la production de diesel.

Generating three centimeters of top soil takes 1,000 years, and if current rates of degradation continue all of the world's top soil could be gone within 60 years, a senior UN official said
