Implications of the Gardiner Dam on interregional competition in the marketing of selected agricultural products
Hemstad, John Franklin
The purpose of this study was to determine what implications the development of irrigated production in the Gardiner Dam region of Central Saskatchewan would have on agricultural production and marketing patterns in other regions of Canada. A spatial equilibrium linear programming model capable of determining optimum regional production patterns on the basis of economic efficiency was employed. The model considered three crops - table potatoes, sugar beets and fresh carrots, under various 1966 and 1976 regional conditions. To aid in accomplishing the objective of the study, a comparison was made of the results when non-irrigated and irrigated production in the Gardiner Dam area were considered. The study revealed, under both 1966 and 1976 conditions, that the Gardiner Dam irrigation area could allow Saskatchewan to become selfsufficient in meeting all of its potato demand during the "in-season" periods. It did not appear feasible to export potatoes from the irrigation area outside the province. It was shown that the Gardiner Dam area was competitive in meeting all of Saskatchewan's sugar requirements, but that development of such a crop hinges directly upon the construction of a local sugar refinery. The study revealed that fresh carrot production could be expanded in all regions of Western Canada. The degree of development in other regions would directly affect the acreage possible in the irrigation area. The results of this study are particularly useful in regional long range planning and policy making by governmental institutions.
