To meet the aspirations of the UNFCCC Paris Climate Agreement to limit increases of global mean temperature to well below 2C, future scenarios assume the large-scale use of afforestation and biomass energy with carbon capture and storage (BECCS) to remove carbon dioxide from the atmosphere. The availability of land and biomass residue streams (e.g. waste material from harvest) are key constraints on the ability to deliver these negative emission technologies at scale, given a context of global dietary trends and the inefficiencies in the global food system. In this directly-funded NERC PhD the student will critically assess the land use and residue stream assumptions used in future scenarios. You will start by critically examining the land-use scenarios from existing integrated assessment model studies used of the Shared Socioeconomic Pathways (SSPs). The next stage will involve a global spatial analysis of land-use and residue streams under a range of dietary and food system efficiency scenarios, using historical data and future UN projections of demand for food and other plant and animal products. Within this, the student will explore alternative scenarios of how demand for food and fibre is met and how it translates into land-use, which depends on factors such as crop yield, type of meat consumed, meat production systems and levels of waste within the food system. There will be opportunities to extend the analysis to consider economic trade-offs.

为了满足UNFCCC巴黎气候一致性的愿望，即将全球平均温度升高升至2C低于2C，未来的情景假设使用碳捕获和储存（BECC）大量使用了造林和生物质能量，以从大气中去除二氧化碳。鉴于全球饮食趋势和全球食品系统中的效率低下，土地和生物量残留物流的可用性（例如，收获的废料）对交付这些负发射技术的能力是关键的限制。在这个直接资助的NERC博士学位中，学生将批判性地评估未来场景中使用的土地使用和残留流假设。首先，您将对共享社会经济途径（SSP）的现有综合评估模型研究的土地利用方案开始。下一阶段将使用历史数据和未来对食品以及其他动植物产品的需求预测，对一系列饮食和食品系统效率方案进行土地利用和残留流的全球空间分析。在此中，学生将探讨如何满足食物和纤维的需求以及如何转化为土地利用，这取决于诸如作物产量，食用肉类的肉类，肉类生产系统以及食品系统中的废物水平等因素。将有机会扩展分析以考虑经济权衡。
