Carbon emission reduction: News and technology

[Brian Peacock]

i can't find that specific video, though the subject is popular, and there's no way i'm looking at it small format, when i might need the subs

I think the full video comes out on Sunday.

Not sure I thought this was even possible

An Australian farmer has held the first carbon-neutral cattle sale – here’s how it works
Seven hundred breeding cows and heifers reared in a ‘carbon neutral farming system’ sold in NSW on Thursday. But can a live cow be carbon neutral?

I always wondered. The land needed. Bit of a waste of land, but not wrong if all you can grow is grass. We have sandy soil in the West for that.
Numbers for a cow and calf. The bull is on his own.
Regional Space Guide (in Hectares)
High-Rain / Lush Land: 0.2 to 0.8 hectares per cow.Average Temperate Pasture: 0.6 to 2 hectares per cow.Arid / Dry Rangeland: 4 to 20+ hectares per cow.

Most grazing animals in the West have their diets supplemented with soy- and grain-based feeds.

... Almost half (44%) of the world’s habitable land is used for agriculture. In total, it is an area of 48 million square kilometers (km2). That’s around five times the size of the United States.

Croplands comprise one-third of agricultural land, and grazing land comprises two-thirds.

However, only half of the world’s croplands are used to grow crops that humans consume directly. We use a lot of land to grow crops for biofuels and other industrial products, and an even more significant share is used to feed livestock.

If we combine global grazing land with the amount of cropland used for animal feed, livestock accounts for 80% of agricultural land use. Most of the world’s agricultural land is used to raise livestock for meat and dairy.

Crops for humans account for 16%. And non-food crops for biofuels and textiles come to 4%.

Despite the vast land used for livestock animals, they contribute quite a small share of the global calorie and protein supply. Meat, dairy, and farmed fish provide just 17% of the world’s calories and 38% of its protein. ...

Rewilded land remains green amid drought-stricken English countryside, images show

...More than 90% of the UK’s wetlands have been lost over the last century and restoring the habitats to make them wet again is becoming increasingly important for climate adaptation, water security and nature recovery.

Harry Bowell, the National Trust’s director of land and nature, called on the government to boost its efforts to invest in nature-based solutions to help the country become more resilient.

“This year’s summer has been a stark warning of how our weather systems are changing,” he said. “Climate change is no longer something of the future – it’s happening here and now. With another El Niño predicted for next year it’s likely many more of us will be subject to more frequent floods, droughts, heatwaves and wildfires, and we are not immune.”

Particularly interested in this as our group helps organise small-scale rewinding projects that involve connecting urban and rural secondary schools.
