This is a problem that will likely take decades to solve. In China's north and north-west, herders have increased their herds of goats and sheep since the reform and open up period began. Eventually, the number of grazing animals grew to numbers that the land could no longer support, leading to grasses being uprooted and feeding desertification. Mongolia started their economic liberalization later than China, but now their animal herds have also grown much too big, leading to desertification in large parts of Mongolia.
The solution is:
-Penning of herd animals, preventing them from roaming freely over the land.
-Planting of suitable grasses to try to regrow the grasslands.
-Harvesting the grass and bringing it to the animals, rather than the other way around.
-In the meantime, feed will have to be brought in from outside the region.
China has had some success with this practice, but once the desert has set in, it is very difficult to bring the grassland back. It takes years and years and years. But as they say: Never give up!
