The goal of the study is to find a sustainable way to manage grasslands on the Qinghai-Tibetan Plateau. The researchers found that there is a problem with the balance between the amount of grass available and the needs of livestock, leading to overgrazing. To address this issue, they suggest using an integrated crop-livestock system to improve livestock production efficiency and protect natural grasslands. This approach aims to help both the environment and the livelihoods of pastoralists in the region.
