    I have to wonder how these things will play out over decades.

    Making even small changes to ecosystems can cause massive issues as chain reactions are created, and China has been undertaking massive geo-engineering projects.

    I hope they play out positively and the world gets a framework on how to do it safely and sustainably.

      Yeah, combating spreading desertification is good as it protects the existing ecosystems that surround the desert. But some people have a misguided belief that deserts are useless areas and greening entire deserts would be a net positive. Deserts are an incredibly complex environment, even if we know less about them than areas where we humans live in larger numbers.

      We know the Sahara desert is responsible for soil replenishment of Carribbean islands and South America. The knock on effects of removing a desert could be disastrous.

      China has actively been combating the spread of desert in the region, trying to return the local ecosystem to what it was like millennia ago, as far as I know, they aren’t intended to turn every desert in the country into a forest, just trying to restore the natural environment to previous conditions.

          The Sahara was probably originally made by humans over farming/grazing the land in the first thousand years of agriculture. Egyptians even had interesting records of large rivers going through the area.

          Search Lake Megachad. Basically it’s a tale of ancient overgrazing of a fragile ecosystem causing a giant dust bowl and major expansion of deserts, causing one of earths largest lakes to almost disappear

          Human activities even before capitalism have created and spread desserts. Basically, humans have been clearing out forests to make crop lands since the dawn of agriculture. But crop lands are susceptible to desertification because tree trucks/canopies block wind, and their roots hold soil preventing erosion from wind/landslides/floods.

          Capitalism and the industrial revolution speed up trends that previously took centuries and millenia into ones that occur over years and decades. There will likely come a time, if we don’t reverse course, where the amazon will be deforested and become a dessert.
