IRRIGATION SUSTAINABILITY – SASKATCHEWAN ACTIVITY

Pages 457-465 | Published online: 23 Jan 2013
 

Abstract

Irrigation is essential for world food production. In Western Canada, irrigation has been viewed historically as a mechanism for stabilizing agricultural production by overcoming problems associated with drought, and allowing for the diversification of crop production. It is critical that the long term environmental effects of irrigation be understood if the negative impacts on soil and water are to be avoided and irrigation is to continue its contribution to the diversification of agriculture. The Federal/Provincially-funded Saskatchewan Irrigation Development Centre (SIDC), in Outlook, Saskatchewan, has developed an applied research and demonstration program with four projects to promote sustainable irrigation: pesticide and nutrient losses and groundwater contamination under irrigated conditions; evaluation of the effects of irrigation on soil quality; water conservation and water use efficiency; and effluent irrigation management. These programs were funded through the Canada-Saskatchewan Agriculture Green Plan Agreement (CSAGPA).

L’irrigation est essentielle pour la production alimentaire mondiale. Dans l’Ouest du Canada, l’irrigation a longtemps été perçue comme un mécanisme de stabilisation de la production agricole en ce qu’elle permet de surmonter les problèmes liés à la sécheresse et de diversifier les cultures agricoles. Il est crucial de bien saisir les effets à long terme de l’irrigation sur l’environnement si l’on souhaite éviter les répercussions négatives sur les sols et sur l’eau et continuer de profiter de l’apport de l’irrigation au chapitre de la diversification de l’agriculture. À Outlook, en Saskatchewan, le Centre de développement de l’irrigation de la Saskatchewan, qui bénéficie d’un financement fédéral-provincial, a mis au point un programme-pilote et un programme de recherche appliquée comportant quatre projets de promotion de l’irrigation durable : pesticide et pertes en substances nutritives et contamination des eaux souterraines dans un contexte d’irrigation; évaluation des effets de l’irrigation sur la qualité du sol; conservation de l’eau et efficacité de l’utilisation de l’eau et gestion de l’épandage des effluents par irrigation. Ces programmes furent financés aux termes de l’Entente Canada-Saskatchewan sur le plan vert en agriculture.
