Roots — an interdisciplinary link

Wageningen 2008WICC, Wageningen, The Netherlands
10-12 September 2008
A WIMEK-NUPUS-PE&RC WORKSHOP

Rationale

Roots are identified as an upcoming topic in hydrology, in climate change and in resource use efficiency studies. This is however not yet reflected in the research agenda. Work is going on, but often the activities are modest and very scattered. To be better able to appreciate what has been established, what is going on and what still needs to be done, SEG (Soil physics, Ecohydrology and Groundwater management ), in collaboration with different chair groups from Wageningen university (SOQ, ESS and HWM), and funded by the research school WIMEK, is organizing a 3-day workshop on this topic. Main objectives of the meeting are:

  • To provide interdisciplinary links to plant scientists and hydrologists,
  • to inform interesting parties of what is going on,
  • to identify and detail the problems associated with root system modelling,
  • to make an inventory of current understanding of root uptake strategies (water and nutrients),
  • to inform one another on ongoing research projects, and
  • to discuss future research needs and prospects for collaboration.
