Input constraints to food production: the impact of soil degradation

@Botanygeek There's a bit more evidence on #soildegradation now: FAO https://t.co/CKwiJc4A2v Lancaster (only under 100y in 16%) https://t.co/TpxDhrrxVR Rickson (area of UK every year, pre-dates yr article) https://t.co/1i3NJsQLun

@aaronshem @ShellenbergerMD https://t.co/6wzlZUEWEN “Every year, an estimated 12 million hectares of agricultural land are lost to soil degradation, adding to the billions of hectares that are already degraded”

@PowlsonDavid @Botanygeek I had a rummage, suprirsingly thin. 1/2 There's this, saying we lose an estimated 12m ha pa: https://t.co/13H2ehtjWK The FAO mention 60 years, but I can't find their source. This say by 2050 we'll have a quarter of the arable lan

12m ha land lost 2 soil degradtion = annually up 20m t loss of grain https://t.co/oMglhXHnNZ

I'm readingInput constraints to food production: the impact of soil degradation http://t.co/jUVhtleZCq is key to ensure food for humans

12,000,000 hectares of agricultural land are lost annually to soil degradation (http://t.co/SCLVbSoqHM), an area larger than Pennsylvania
