Taking advantage of rising CO2 to maximise ecosystem productivity

大气中二氧化碳浓度的上升为提高生态系统生产力提供了机会，特别是在农业系统中。在多大程度上是高度不确定的，特别是当与不断变化的温度和降水结合在一起时。最近的研究表明，季节性供水是草地生产力对高二氧化碳浓度响应的最强控制因素。该项目旨在阐明管理这一反应的过程，并开发简单的模型，以便计算出最大化二氧化碳浓度上升带来的生产率好处所需的条件。

The rising atmospheric concentration of carbon dioxide provides an opportunity to increase ecosystem productivity, especially in agricultural systems. To what extent is highly uncertain, particularly when combined with changing temperature and precipitation. It has recently been demonstrated that seasonal water supply is the strongest controller of the productivity response to high carbon dioxide concentrations of grasslands. This project aims to elucidate the processes governing this response and develop simple models that could allow the conditions required to maximise the productivity benefit from rising carbon dioxide concentration to be calculated.
