What is the environmentally optimal number of ruminant livestock in the UK? Investigating the potential for enhancement of natural capital stocks

摘要反刍动物对环境的影响是发展可持续粮食生产系统的一个关键问题。我研究了增加农田自然资本存量的潜力，以抵消牲畜对环境的影响，同时增加额外生态系统服务的流动，并提高农场生产率。我的DPhil专注于i)将树木整合到反刍动物放牧景观中，ii)将反刍动物引入耕作系统，以及iii)国内和海外反刍动物生产的平衡，以达到最佳的环境结果。BBSRC的任务这项工作属于BBSRC的优先领域“可持续提高农业生产”和理事会的优先事项“环境和土地利用”和“全球粮食安全”。

Summary The environmental impacts of ruminant livestock are a critical issue in developing sustainable food production systems. I research the potential for enhancement of natural capital stocks on farmland to offset environmental impacts of livestock, whilst increasing flows of additional ecosystem services and improving farm productivity. My DPhil focuses on i) integrating trees into ruminant grazing landscapes, ii) introducing ruminants into arable systems and iii) the balance of domestic and overseas ruminant production that is optimal for environmental outcomes. BBSRC remit This work falls under the BBSRC priority area "sustainably enhancing agricultural production" and Cross Council priorities "environment and land use" and "global food security".
