主 题：Pastureland Carbon storage Greenhouse gas emissions Offsetting
摘 要：Grasslands(natural,semi-natural and improved)occupy approximately one-third of the terrestrial biosphere and are key for global ecosystem service provision,storing up to 30%of soil organic carbon(SOC).To date,most research on soil carbon(C)sequestration has focused on croplands where the levels of native soil organic matter(SOM)are typically low and significant potential exists to replenish SOM ***,with the renewed push to achieve“net zeroC emissions by 2050,grasslands may offer an additional C store,utilising tools such as ***,we critically evaluate the potential for biochar as a technology for increasing grassland C stocks,identifying a number of practical,economic,social and legislative challenges that need to be addressed before the widescale adoption of biochar may be *** critically assess the current knowledge within the field of grassland biochar research in the context of ecosystem service provision and provide opinions on the applicability of biochar as an amendment to different types of grassland(improved,semi-improved and unimproved)and the potential effect on ecosystem provision using a range of application techniques in the topsoil and *** concluded that the key question remains,is it possible for managed grasslands to store more C,without causing a loss in additional ecosystem services?To address this question future research must take a more multidisciplinary and holistic approach when evaluating the potential role of biochar at sequestering C in grasslands to mitigate climate change.
