Protected Agriculture (PA) is defined as “modification of the natural environment to achieve optimal growth” (Jansen and Malter 1995). It is being viewed by several countries within the Region as a viable technology to attain a level of self-sufficiency in vegetable production and as a potential adaptation option to address the vagaries of climate change on food supply.  Despite the demonstrated potential of protected agriculture, many growers have been unable to sustain and/or optimize crop yields. This is linked in part, to inappropriate designs of protected structures for the climatic conditions of the Region and production practices
