Hey there, explorers! ๐ Have you ever heard of the Qinghai-Xizang Plateau? It’s often called the “roof of the world” because it’s so high up! ๐๏ธ
Recently, some super-smart scientists from the Chinese mainland have been using satellites in space ๐ to help protect this amazing place. Want to know how? Let’s dive in! ๐ง
These scientists created special maps called datasets using pictures taken from satellites high above the Earth. ๐ก These maps show where people have planted special grasses called “cultivated pastures.” ๐พ
What’s a cultivated pasture?
Cultivated pastures are areas where people plant and grow grasses and plants on purpose to feed animals like sheep and yaks. ๐๐ This is different from natural grasslands, where plants grow all by themselves without much help from people. ๐ฟ
Why is this important?
The grasslands on the Qinghai-Xizang Plateau are super important! They help store carbon (which is good for our planet ๐), keep water and nutrients cycling, and they’re home to many plants and animals. Plus, they support the people who live there and take care of animals. ๐พ๐ฉโ๐พ
What did the scientists find?
By looking at satellite data from 1988 to 2021, the scientists found that the areas with cultivated pastures got much bigger! ๐ฑ The total area is now about 1.57 million hectares (that’s like 2 million soccer fields!). Most of these pastures are in Qinghai Province (70%), and the rest are in the Xizang Autonomous Region (30%).
Helping the planet
By knowing where these cultivated pastures are, scientists can help make sure the grasslands stay healthy. ๐๏ธ This means better homes for animals, healthier plants, and happier people!
The scientists are going to keep studying to see how changing natural grasslands into cultivated pastures affects the environment. ๐ Their work helps protect the “roof of the world” for everyone!
Isn’t it cool how satellites in space can help us take care of our planet? ๐๐
