Lecturer in Agrometeorology


After completing his Honours degree in Hydrology, Mr CLulow left academia and spent a few years managing dairy farms, a trout hatchery and then as a process manager for an aerial photography company. He returned to Hydrology via a small consulting firm for a year after which he spent seven years with the CSIR, first as a field technician, and then after the completion of his MSc., as a researcher in land-use hydrology. UKZN offered an opportunity to complete a PHD in Water-use of indigenous vegetation of the Maputaland Coastal Plain during which he was appointed as a lecturer in Agrometeorology.

Current Research Projects

  • Open water evaporation using micrometeorological methods (WRC 2014-2017)
  • Water use of strategic biofuel crops (WRC 2015-2020)
  • Establishment of a more robust observation network to improve understanding of global change in the sensitive and critical water supply area of the Drakensberg
