Abstract:

Grassland is one of the most important terrestrial ecosystems on earth, and brings humankind a series of ecosystem services, including food production, climate regulation, air purification, water conservation, wind prevention and sand fixation. Nearly half of the grasslands in the world are affected by climate change and human factors, and thus display different degrees of degradation. This degradation has become one of the world’s ecological and environmental problems. Much research on restoration of degraded grasslands has been carried out around the world with findings often leading to change in practice, and great progress has been made. However, at the beginning of the UN Decade on Ecosystem Restoration (2021-2030), a new generation of restoration research and practice projects is needed to cope with global environmental challenges. This paper summarizes the research and practice of degraded grassland restoration around the world, in the hope of learning from the existing grassland restoration work. On this basis, it is anticipated that we can map out the main direction of future research on degraded grassland restoration, and formulate reasonable restoration plans for degraded grassland, so as to provide reference information for new grassland restoration research and practice in the context of global change.

Key words: grassland, degradation, restoration, research, practice
