DESCRIPTION:Plants strongly shape the consequences of environmental change 
 for water resources and climate. For example\, without vegetation\, intens
 ified carbon dioxide (CO2) emissions by fossil fuel burning would act on w
 ater resources only via the increased greenhouse effect and its consequenc
 es for precipitation and evaporative demand. However\, plants respond dire
 ctly to elevated atmospheric CO2 concentrations (eCO2)\, e.g. by reducing 
 their stomatal conductance and/or increasing their CO2 assimilation and gr
 owth rate. This has an additional effect of eCO2 on our water resources by
  modified vegetation water use and on the climate by modified surface albe
 do\, as well as modified latent and sensible heat fluxes. Such plant-envir
 onment interactions can further have profound impacts on carbon and nutrie
 nt cycling and carbon sequestration processes. Plant responses to environm
 ental stimuli vary widely between species and growth environments and henc
 e empirical approaches to predict these responses are fraught with major d
 ifficulties and uncertainty.  Here\, I will present an optimality-based ap
 proach to predict plant and vegetation responses to environmental forcing\
 , inspired by natural selection and the selective pressure to make the bes
 t out of the available resources. I will present some of the insights that
  can be gained from such an approach and then highlight the immense challe
 nges of quantifying the cost-benefit trade-offs determining the optimal pl
 ant investment strategies into foliage\, roots and water transport tissues
 . Some of the challenges are currently being tackled by the WAVE team at t
 he Luxembourg Institute of Science and Technology (LIST)\, but serious pro
 gress will only be achieved if a larger part of the scientific community p
 uts more focus on cost-benefit trade-offs underlying plant behaviour\, lin
 king the functions of plant organs to their construction and maintenance c
 osts in different environments.\n&nbsp\;\n\nZoom-Link for joining the talk
