Towards design of chemical-resilient agricultural landscapes

项目概述：英国生物多样性受到威胁：自1970年以来，陆地和淡水物种的丰度下降了13%，15%的物种面临灭绝的威胁。由于英国71%的土地用于农业，任何阻止英国生物多样性下降的努力都必须考虑如何管理农业景观。这个CASE博士项目将解决维持英国粮食生产以满足国家粮食安全需求的双重挑战，同时也实现英国在2030年停止生物多样性丧失的承诺。为了做到这一点，研究将涉及对农业景观的未来替代方案的设想；这可能包括从相对简单的管理特征到生境创造、替代种植系统以及创新粮食生产系统（如再生农业和城市农业）的作用。该项目将在基线（当前）条件下评估化学品和其他压力源对生物多样性和其他生态系统服务提供的影响，然后将其与未来不同情景下的景观水平提供进行比较。Colin Brown（约克）、Lorraine Maltby（谢菲尔德）、Roman Ashauer（先正达）和Mike Fryer（化学品监管部门）的管理团队都拥有丰富的农业系统研究经验，并在环境建模、化学品暴露、化学效应、景观生态学和监管/政策方面具有互补的专业知识。

Project Overview: UK biodiversity is under threat: the abundance of terrestrial and freshwater species has declined by 13% since 1970 and 15% of species are threatened with extinction. As 71% of UK land is used for agriculture, any effort to halt UK biodiversity decline must consider how agricultural landscapes are managed. This CASE PhD project will address the twin challenge of maintaining UK food production to meet demands for national food security whilst also delivering on the UK's commitment to halt biodiversity loss 2030. To do this, the research will involve visioning of alternative futures for agricultural landscapes; this may range from relatively simple management features, to habitat creation,alternative cropping systems, and the role of innovative food production systems such as regenerative agriculture and urban agriculture. The project will evaluate impacts of chemicals and other stressors on biodiversity and delivery of other ecosystem services under baseline (current) conditions, and then compare these with landscape-level delivery under the alternative future scenarios.The supervisory team of Colin Brown (York), Lorraine Maltby (Sheffield), Roman Ashauer (Syngenta) and Mike Fryer (Chemicals Regulation Division) all have extensive experience of research into agricultural systems, and bring complementary expertise in environmental modelling, chemical exposure, chemical effects, landscape ecology, and regulation/policy.
