Past and future effects of climate change on the carbon-water balance of plants

点击翻译按钮获取中文摘要

Over the coming century, climate change will profoundly impact Australian vegetation via the direct effects of elevated atmospheric carbon dioxide (CO2) on plants and the indirect effects of CO2-forced changes in rainfall and temperature, with major implications for agricultural production and water resources. This project will address these threats by providing new tools for measuring and predicting vegetation-climate feedbacks. It will determine the combined effects of elevated atmospheric CO2 and drought on the productivity of natural and agricultural landscapes, and provide the biophysical framework for developing the next generation of high-yielding, drought tolerant crop varieties for the rapidly approaching greenhouse world.
