It would appear that the desert is growing in other parts of the world.

It would appear that the desert is growing in other parts of the world.



Air pollution seems to have a direct and negative impact on grain production in India, a US study warned on Monday, with recent increases in smog decreasing projected yields by half.

Analysing 30 years of data, scientists developed a statistical model suggesting that air pollution caused wheat yields in densely populated states to be 50% lower than what they could have been in 2010.Up to 90% of the decrease in potential food production seems to be linked to smog, a mix of black carbon and other pollutants, the study said.

More than 40% of China's arable land is suffering from degradation, seriously reducing the country's capacity to produce food for the world's biggest population, Xinhua reported Tuesday.
The rich black soil in Northeastern Heilongjiang province, which forms part of China's bread basket, is thinning, while farmland in China's south is suffering from acidification, the report said, citing agriculture ministry statistics.

Degraded land typically includes soil suffering from reduced fertility, erosion, changes in acidity and the effects of climate change as well as damage from pollutants.

China's growing population and accelerating urbanization are eroding the country's arable land and threatening food security.

it's not just other parts of the world. For example in Texas, you can see the desert growing. If you look at Google Earth you can time travel back in time and see how it is moving.

Wyoming is getting bad too. We have dust storms that probably equal the desert.

In many places, glaciers have disappeared or decreased in size. THis makes a huge difference, especially in dry areas like the intermountain west, because that water later goes to the desert and can make it a green or yellow prairie instead of a brown sandy desert.

Reverse desertification? Make the desert go green again?

Nature can do it. Without bulldozers, without expense or (human) work? Incredible.

Beavers in the desert!! No trees for dams, no problem. Build dams with rocks & mud!

People release beavers on their land.

Watch the PBS documentary online at this link:

Any chance someone can summarise how beavers helped in the desert? I can't access this video because I don't live in the USA.

Beavers are native in North America, Europe & Asia. If you live in one of those places... maybe this can help. But you have to see the documentary, there is too much to tell.


Try going through a "proxy server" just Google "proxy server", they are often listed by country and you can use one in the US. Then cut & paste the link I gave on my post. Good luck.

Oops! There was already on a topic on the PBS beaver documentary in the permies forums. From way back in June.
