Hi all, I'm trying to figure out what I make of the Great Green Wall of China. I love their emphasis on reversing desertification, but I'm not sure about the way they are going about it. The wiki reports that there are concerns about planting such vast quantities of trees without the water infrastructure to support them, eating into underground water aquifers which may be disastrous for some of the remaining desert farmers. Artificial desalination without a high local population just isn’t practical or economic. (Most of China's population is in the East Coast of China, not the North West desert regions). They need to plan to trap the naturally occurring rainfall as best they can, maybe using a Tal-Ya water box every few trees or bushes to help collect morning dew where appropriate. At least such a plastic box is passive, and not energy intensive. The wiki also says mono-culture forests are not as good for ecosystem biodiversity and birds and other species are not as attracted to them as they would be to more natural forest plantings, which of course are more expensive and difficult to arrange. https://en.wikipedia.org/wiki/Three-North_Shelter_Forest_Program What does everyone make of it? What species of plants can survive in such low rainfall areas? Is there an economic rationale to pump water up there, or divert it from the Yellow river to green these deserts? Are there areas that could host a "Las Vegas" of North West China for eco-tourism, resorts, golf, or other activities in a re-greened desert? For instance, Time Magazine reports Kubuqi, for one, boasts China’s largest single-stage solar farm, boasting 650,000 fixed and sun-tracking panels, which together channel 1,000 megawatts of electricity into the national grid — about half the power-generating capacity of the Hoover Dam. A team of 47 households are employed to maintain the panels. “Everyday each household can clean more than 3,000 panels using high pressure water jets,” says chief engineer Tian Junting. “And the run-off water feeds the crops that grow underneath.” But the Kubuqi desert only has 740,000 people trying to rejuvenate 18,600 sq km of desert!
