Insects are reported to be in rapid decline worldwide, driven principally by changes in land use and climatic conditions. At the same time, insects provide many important services that benefit agriculture, including pollination and control of crop pests. We still have an incomplete understanding of how changes in land use and climate drive insect declines worldwide, however, and consequently where insect biodiversity is most at risk. This project will investigate how changes in land use and climate drive changes in the biodiversity of pollinators and pest-predators by collating a global database on the identity of pollinating and pest-controlling species to be used in concert with global abundance data on the distribution of biodiversity along both climate and land-use gradients. The project will, furthermore, identify where the most pronounced declines in the diversity of pollinators and pest-controllers overlap with agriculturally important areas, and which regions of the world are thus at risk of food shortages due to degradation in ecosystem services. This assessment will be made both at the current time as well as modelled into the future with respect to RCP scenarios of climate and land-use change.

据报告，昆虫在世界范围内迅速减少，主要是由于土地使用和气候条件的变化。与此同时，昆虫提供了许多有益于农业的重要服务，包括授粉和控制作物害虫。然而，我们仍然不完全了解土地利用和气候变化如何导致全球昆虫减少，因此昆虫生物多样性最危险。该项目将调查土地使用和气候的变化如何驱动授粉者和害虫捕食者生物多样性的变化，方法是整理一个关于授粉和害虫控制物种身份的全球数据库，与关于生物多样性沿着气候和土地使用梯度分布的全球丰度数据一起使用。此外，该项目还将确定授粉者和害虫控制者多样性下降最明显的地区与农业重要地区重叠的地方，以及世界上哪些地区因生态系统服务退化而面临粮食短缺的风险。这一评估将在目前进行，并在未来对气候和土地利用变化的RCP假设情景进行模拟。
