To meet carbon emissions targets, more than 30 countries have committed to boosting production of renewable resources from biological materials andconvert them into products such as food, animal feedand bioenergy. In a post-fossil-fuel world, an increasingproportion of chemicals, plastics, textiles, fuels and electricity will have to come from biomass, which takesup land. To maintain current consumption trends theworld will also need to produce 50–70 percent more foodby 2050, increasingly under drought conditions and onpoor soils.

A data-based method to distinguish climate and land use change impacts on streamflow has been previously developed and needs further evaluation through a large sample study. This study aims to apply the method to a large sample set of 472 catchments in the United States and Australia. The method calculates the water and energy budget of a catchment which can be translated to climate and land use induced changes in streamflow between two periods: a pre-change and post-change period.
