The urgent need for systemic change in order to avoid biodiversity collapse and further climate catastrophe echoed across the opening weekend of the IUCN World Conservation Congress in Marseille, France. In a speech to kick off the congress on Friday, French President Emmanuel Macron stressed the importance of addressing both biodiversity and climate change in an integrated way, saying, “There is no vaccine for a sick planet.”(No paywall)
Five farm-state Republicans unveiled a package of climate bills that in one instance would allow private-sector donors to USDA conservation accounts to specify where the money would be spent and put "a name or a brand" on a project. Another of the bills would allow landscape-scale forest management projects of up to 75,000 acres — bigger than the District of Columbia — to reduce wildfire risk through forest thinning, controlled burns, salvaging dead or endangered trees, and creation of "fuel breaks" up to one-half mile wide.
Extolled as a defense against erosion and nutrient loss during fallow seasons, cover crops are being planted on a larger portion of U.S. cropland than before, said USDA economists. Plantings expanded 50 percent in a five-year period, but still only 5 percent of cropland is sown with them—and incentive payments are an important factor in adoption of the practice.
U.S. cropland could lose two inches of soil nationwide by 2035 if climate change delivers its expected droughts and floods, said the Union of Concerned Scientists on Thursday. In a report, the group recommended such steps as crop insurance discounts for farmers who adopt practices that reduce erosion and improve soil health.
In less than a decade, U.S. corn, soybean and wheat fields wiped out an expanse of native grasslands and other ecosystems larger than the state of Maryland, according to a new analysis, destroying crucial wildlife habitat and spewing carbon dioxide into the atmosphere. The new fields produced lower crop yields than existing farmland.(No paywall)
Agricultural processor Cargill said on Wednesday that it would support the adoption of regenerative agriculture practices on 10 million acres of North American farmland over the next 10 years.
Often cited as a way to reduce erosion or improve soil quality, cover crops are also useful in controlling weeds that have developed an herbicide tolerance, said a survey of farmers by the Conservation Technology Information Center on Wednesday.
Rattan Lal, one of the world's leading soil scientists, is this year's winner of the $250,000 World Food Prize, "the Nobel of agriculture," for his breakthrough research on the importance of carbon to soil health and the potential of carbon sequestration to mitigate climate change. Lal's research "transformed the way the world saw soils," said the foundation that awards the annual prize.
As efforts to wean society off fossil fuels have stalled, “natural climate solutions” such as soil carbon sequestration have rapidly gained steam. But, as Gabriel Popkin reports in FERN's latest story, published with Yale Environment 360, "a growing number of scientists worry that mounting societal pressure to do something to counter climate change is pushing money into so-called carbon farming before the science needed to underpin it is mature."(No paywall)
