  • Wicked' US weed has put down roots locally 
    Reinhardt, Carl Frederick (Charlie) (Plaas Publishing, 2018-09)
    The term ‘wicked’ weed is borrowed from the field of sociology where a wicked problem is defined as one without clear causes or solutions, and thus difficult or impossible to solve (Shaw, 2016, Weed Science: Special Issue, ...
  • Willingness-to-pay for environmental services provided by trees in core and fringe areas of Benin City, Nigeria
