China and India Lead the Way in Greening (nasa.gov) 115

hackingbear writes: The world is literally a greener place than it was twenty years ago, and data from NASA satellites has revealed a counterintuitive source for much of this new foliage. A new study shows that China and India -- the world's most populous countries -- are leading the increase in greening on land. The effect comes mostly from ambitious tree-planting programs in China and intensive agriculture in both countries. Ranga Myneni of Boston University and colleagues first detected the greening phenomenon in satellite data from the mid-1990s, but they did not know whether human activity was a chief cause. The research team found that global green leaf area has increased by 5 percent since the early 2000s, an area equivalent to all of the Amazon rainforests. At least 25 percent of that gain came in China. "China and India account for one-third of the greening, but contain only 9 percent of the planet's land area covered in vegetation," said lead author Chi Chen of Boston University. "That is a surprising finding, considering the general notion of land degradation in populous countries from overexploitation." China's outsized contribution to the global greening trend comes in large part from its programs to conserve and expand forests (about 42 percent of the greening contribution). These programs were developed in an effort to reduce the effects of soil erosion, air pollution, and climate change.

      "Greening" by creating forests where previously there were none counts as a form of climate change too.

      While green forests are cool, are there concerns for the previous non-forest ecosystems that were there?

      Maybe instead of building a wall along the border with Mexico, we should be planting trees along it?

      I mean, not normal trees, but Normandy-like hedgerows that were impassable by the US troops in WWII. They needed to mount tusk-like diggers on Sherman tanks to get through.

      It would keep folks from sneaking across the border illegally, and be Green, as well.

      . . . unless the border crashers get their hands on some Sherman tanks.

        No we don't We actually do most of the science that is proving it is a issue. If it wasn't for NASA research in Antarctica and from space we wouldn't never have known about the Ozone issue with CFC till it was to late. It is only small, but loud, minority that denies the issue.

        There are far more trees in NA today then there were in 1900.

        Actually, if the climate supports it, that would be a good idea. Problems include growing a hedgerow being labour intensive as you have to partially cut the stems and weave them together, but you could hire illegals and taking a while to grow.
        Besides the traditional Hawthorne, you could plant a Barberry or Pyracantha hedge. I knew someone with a Barberry one, it was impassible without a chainsaw and even with, those 2 inch needle sharp thorns were horrible, go right through most shoes.

    It's like everywhere else has recognized that the cost of deploying renewables are now cheaper than their equivalent fossil fuels counterparts.

    It makes more economic sense to be green than it does to be dirty...

    The article is about literal greening of areas of course, but the underlying reason is similar.

    • As I pointed out to somebody else below, America, like most of the west, has gone down every year for the last 10, until this year.

        Sure, we reached peak per capita CO2 production with nowhere to go but down while China and especially India are still relatively low per capita.
        The real problem is how much CO2 we produce compared to the Vatican if we're going to compare countries without considering size or population.

        • Actually, that is not true.
          CHina is already above per capita that they need to be. Hell, they were above EU's average clear back in early 2010's, and continue to grow theirs. Yet, EU who is less than China, continues to work to drop theirs. Why? Because emissions are emissions. The ONLY time that CHina flat lined was when their economy had crashed and they were lying about it (2014-6). But, they have NOT dropped emissions.

India needs to stop their CO2 growth, but thankfully, they are fairly low (though they are 3rd highest emitter).

            The only thing that matters is per-capita pollution - everything else is rationalization for western arrogance and entitlement.

    China is reclaiming desert with grid plantings.

    My understanding is that the USA has at least as many forested acres as ever, but a lot less biomass, and a lot of dead trees. Old growth is taller so it slows wind down more, and it's also more massive so it fixes more carbon. (Trees only grow from a thin layer beneath the bark, and the rate of growth is limited by photosynthesis, with larger trees able to do more of it because they have more leaf area with which to receive insolation.)

    Is there a biomass index?

      There's one for the US [fs.fed.us]. Presumably other governments have something similar.

    We have absolutely got to do something about climate change. Most of what we've got to do would also make the world a lot better in sundry other ways.

    If we helped the landscape keep multiple stories of vegetation, and worked out ways to scale orchards designed the same way, it would make for great resistance to drought and a stable food supply, and over time, correct for this spike in greenhouse gasses.

    Entire horticultural and early agriculture civilizations have been founded not on controlling the landscape's entire harvest, but on enriching it and reaping the surplus. In this way of life, economy and environment are not at all at odds. In fact, they are interdependent. You can look at terra preta and its history in the Amazon basin for an example of a long-term, large-scale win-win scenario. http://news.cornell.edu/storie... [cornell.edu]

    If you want to see what is happening in China, watch this video, "The Lessons of the Loess Plateau": https://www.youtube.com/watch?... [youtube.com]

    Even if you don't exactly agree with *how* they got it done, the results for the landscape and the prosperity of the people there speak for themselves. Start asking how your local economic and political systems can start to do right by the soil too.

    We have Brazil clear cutting their forest so as to supply Europe with Beef, and CHina with exotic woods.
    Then we have the west which has already done a number on our forest and are not replanting fast enough.
    So, it is good to actually see both China and India showing the rest of the world what needs to happen.
    It will not help that much with the CO2, but it will help absorb pollution, etc.
  • The problem is that China has basically destroyed large segments of it's barrier islands and wetlands that absorb storm damage, so expect to read in a few years about how much damage has dramatically increased in China from storms, that otherwise would have not caused major calamities.

    The man single-handedly planted a 550 hectare forest [aljazeera.com] over a period of 30 years which, oddly enough, brought back animals and even a stream to the barren land.

    He has gone on to plant another 150 hectares of land nearby.
