项目摘要

GGR Topic-Specific Project TypeContextIn absence of human habitation, nearly all land in the temperate biome would be covered by forests holding large quantities of carbon within the trees and the soils. Historically, much of these forests have been cleared to make way for agriculture, releasing most of the carbon into the atmosphere. Converting agricultural land back to forestry therefore offers significant potential for greenhouse gas removal (GGR), however in most instances this would come at the cost of reduced food production. Existing land capability studies [4] indicate that the best locations for afforestation are in some of the most productive agricultural areas, highlighting the conflict between forestry and agriculture.GGR opportunityAgroforestry (AF) is a well-understood land use system which purposefully integrates trees with either arable or pastoral food production. AF is not novel, its many benefits include crop diversification, improved water and nutrient cycling in agricultural landscapes and provision of habitats for biodiversity. A well-planned AF system allows for continued food production, while a small percentage of the land is dedicated to tree planting - usually in single line formations. However, the combination of modern farming methods, existing regulatory regime and the historical distinction between agriculture and forestry currently place 'socio-economic' constraints on wider application of this system within the UK. Research questions and plan of workThis proposal will address the research questions and objectives through five integrated work packages: Work package 1 will estimate GGR potential of AF in the UK under a combination of time (timeframes of adoption of AF across the landscape) and intensity (the proportion of land dedicated to the tree component). The Sheffield Dynamic Global Vegetation Model (SDGVM) will be used to investigate the interaction between crops/pasture and trees. We will develop a new plant functional type to describe and model AF systems and to predict the change in carbon stocks in trees and soil (i.e. the additional GHG removal) when compared to current agriculture. Work package 2 will evaluate the current barriers to AF adoption related to policy and socio-economic considerations. We will develop value propositions designed to incentivise farmers and landowners to commit to AF in both arable and pasture settings.Work package 3 will build on the outcomes of work package 1 and 2 and develop detailed examples of field-scale benefits of AF across different farming systems (arable/pasture), four UK agro-climatic regions and on varying soil types. We will use workshops with farmers to develop realistic scenarios for AF deployment, taking into account wider benefits of avoided emissions through better soil and nutrient management. Work package 4 will upscale the farm-level impacts of GHG removal 'business case' to correspond to the GHG removal scenarios (work package 3) and the evaluation barriers and opportunities of AF adoption (work package 2) to generate agricultural, environmental and energy policy recommendations. Work package 5 will focus on integration and management. We will coordinate and integrate the research development between work packages and work with policy and farming communities through a series of targeted workshops to identify current barriers limiting adoption of AF on a wider scale. InterdisciplinarityOur interdisciplinary approach brings together scientists, social scientists and economists across the Food and Environment Research Themes at the University of Reading. Expertise of collaborators spans research on carbon cycles in agricultural (including AF) and forest ecosystems, modelling plant and soil C dynamics, national and farm-scale rural economy and policy. All have experience in working on interdisciplinary projects and recognise the benefits of this approach to deliver viable solutions.

在没有人类居住的情况下，温带生物群落中几乎所有的土地都将被森林覆盖，森林和土壤中含有大量的碳。从历史上看，这些森林中的大部分都被砍伐，为农业让路，将大部分碳释放到大气中。因此，将农业用地转变为林业为温室气体清除提供了巨大的潜力，但在大多数情况下，这将以减少粮食产量为代价。现有的土地能力研究[4]表明，植树造林的最佳地点是在一些最具生产力的农业地区，突出了林业和农业之间的冲突。GGR机会农林复合系统（AF）是一种众所周知的土地利用系统，它有目的地将树木与耕地或畜牧业食品生产相结合。AF并不新奇，它的许多好处包括作物多样化，改善农业景观中的水和养分循环以及为生物多样性提供栖息地。一个精心规划的农业生产系统可以持续生产粮食，而一小部分土地则用于植树-通常是单行种植。然而，结合现代耕作方法，现有的监管制度和农业和林业之间的历史区别，目前的地方“社会经济”的限制，在英国更广泛地应用这一系统。研究问题和工作计划本提案将通过五个综合工作包解决研究问题和目标：工作包1将根据时间（在整个景观中采用AF的时间框架）和强度（专用于树木的土地比例）估计AF在英国的GGR潜力。谢菲尔德动态全球植被模型（SDGVM）将用于调查作物/牧草和树木之间的相互作用。我们将开发一种新的植物功能类型来描述和模拟AF系统，并预测与当前农业相比，树木和土壤中碳储量的变化（即额外的温室气体清除量）。工作包2将评估与政策和社会经济因素相关的AF采用的当前障碍。我们将制定旨在激励农民和土地所有者在耕地和牧场环境中致力于AF的价值主张。工作包3将建立在工作包1和2的成果基础上，并在不同的耕作系统（耕地/牧场），四个英国农业气候区域和不同土壤类型上开发AF田间规模效益的详细示例。我们将与农民一起举办研讨会，为AF部署制定现实的情景，同时考虑到通过更好的土壤和养分管理避免排放的更广泛利益。工作包4将扩大温室气体清除“商业案例”的农场层面影响，以对应温室气体清除情景（工作包3）和采用AF的评估障碍和机会（工作包2），以产生农业、环境和能源政策建议。第5套工作将侧重于整合和管理。我们将通过一系列有针对性的研讨会，协调和整合工作包之间的研究开发，并与政策和农业社区合作，以确定目前限制更广泛采用AF的障碍。跨学科我们的跨学科方法汇集了科学家，社会科学家和经济学家在阅读大学的食品和环境研究主题。合作者的专业知识涵盖农业（包括AF）和森林生态系统中的碳循环研究，植物和土壤碳动态建模，国家和农场规模的农村经济和政策。所有人都有从事跨学科项目的经验，并认识到这种方法的好处，以提供可行的解决方案。
