The project SOILCLIM will address the pressing need to better predict consequences of climate change on soil biodiversity and ecosystem services in agroecosystems over a European transect of climatic conditions and soil properties and under different long-term fertilization strategies. Together with the development of indicators that can act as an early warning system for a decline of the provision of soil ecosystem services in response to summer drought, the project will provide pivotal evidence of how to counteract negative consequences of climate change on agricultural production. Soil organisms are pivotal for the production of a range of ecosystem services, such as nutrient mineralization and decomposition of organic matter, that contribute to climate mitigation and food production in agroecosystems. The provision of soil ecosystem services in arable land partly depends on the intensity of agricultural management that influences soil biodiversity, but will in the future also be impacted by changing climatic conditions and their interactions with farming. The impact of altered precipitation patterns and soil carbon on soil biodiversity and associated ecosystem functions is on top of the list of eight major research gaps identified by an expert group at the European commission. Summer precipitation is projected to decline across Southern and major parts of Central Europe. Understanding how climate change affects relationships between soil biodiversity and processes across climatic gradients is therefore crucial to determine ecosystem-level responses at large spatial scales and to address threats to the provision of ecosystem services in agricultural soils.We will establish field experiments in Sweden, Germany and Spain that simulate summer droughts to improve our understanding of the links between soil biodiversity and multiple ecosystem functions and services across large spatial scales. These links will be studied in combination with varying levels of soil organic carbon content in agricultural fields and by addressing the interaction with different long-term fertilization strategies. We will use established and innovative methods to develop indicator sets of declines in soil ecosystem service delivery and to predict fluctuations in soil biodiversity in agroecosystems in response to future climate change. We will test the suitability of community metrics that are based on trait information and functional diversity as alternative indicators of soil biodiversity and ecosystem service losses. The project will emphasize the active dialogue with farmers, farmer associations and advisors as an integrated part of the project and will facilitate knowledge exchange between scientific experts and end-users.

SOILCLIM项目将满足更好地预测气候变化对欧洲气候条件和土壤特性样带农业生态系统土壤生物多样性和生态系统服务以及不同长期施肥战略的影响的迫切需要。该项目将制定指标，作为夏季干旱后土壤生态系统服务减少的预警系统，并将提供关键证据，说明如何应对气候变化对农业生产的不利影响。土壤生物对于一系列生态系统服务的产生至关重要，如养分矿化和有机物分解，有助于缓解气候变化和农业生态系统中的粮食生产。可耕地土壤生态系统服务的提供部分取决于影响土壤生物多样性的农业管理强度，但未来也将受到不断变化的气候条件及其与耕作的相互作用的影响。改变降水模式和土壤碳对土壤生物多样性和相关生态系统功能的影响是欧盟委员会专家组确定的八大研究空白之首。预计南欧和中欧主要地区的夏季降水量将减少。因此，了解气候变化如何影响土壤生物多样性和气候梯度过程之间的关系，对于确定大空间尺度上生态系统水平的响应以及应对农业土壤生态系统服务供应的威胁至关重要。德国和西班牙模拟夏季干旱，以提高我们对土壤生物多样性和多种生态系统功能之间联系的理解，大空间范围内的服务。这些联系将结合农田土壤有机碳含量的不同水平进行研究，并解决与不同的长期施肥策略的相互作用。我们将使用既定的和创新的方法来开发土壤生态系统服务提供下降的指标集，并预测农业生态系统中土壤生物多样性的波动，以应对未来的气候变化。我们将测试基于性状信息和功能多样性的社区指标作为土壤生物多样性和生态系统服务损失替代指标的适用性。该项目将强调与农民、农民协会和顾问的积极对话，作为项目的一个组成部分，并将促进科学专家和最终用户之间的知识交流。
