Our August cowl picture by Guiyao Zhou (East China Regular College) reveals how livestock grazing actions probably alter many ecosystem capabilities akin to carbon sequestration. However these results will be markedly regulated by the related world change elements (e.g., warming, nitrogen addition and drought). Right here Guiyao shares the story behind the duvet picture and the grassland ecosystem work it represents.

These images had been taken in Wayan mountain, a really lovely alpine meadow positioned in northeast Tibetan Plateau. My buddy, Miss Junxia Ding and her lab-members have established a long run ecological statement station (PI: Prof. Kelong Chen, Qinghai Regular College) to discover the results of grazing and world local weather change on ecosystems capabilitiesJunxia informed me that this area was as soon as a captivating place with inexperienced grass, recent air and few livestock. Over the previous many years, many vacationers from all around the world have come right here to take pleasure in its beauty each summer season. Sadly, it’s now very stunning to see that inappropriate livestock grazing has brought about severe degradation and desertification issues. Moreover, grazing results will be enhanced or weakened by the related world change elements, akin to warming, nitrogen addition and drought. We’re very unhappy to not see inexperienced grass right here anymore, however simply numerous sheep and rising naked land. As an ecological researcher, we now have nice accountability to report these modifications and share them with extra folks. Due to this fact, there may be an pressing have to develop extra sustainable methods to boost grassland administration. Solely by doing this could we presumably get better its magnificence once more sooner or later.
