Understanding Irrigation Demand in Metro Vancouver

About This Project

In the summer of 2015, the Lower Mainland of British Columbia experienced an unusually hot and dry summer.  The province’s declaration of Level 3 and 4 droughts and the related water restrictions brought water management to the forefront of public discussion. While Metro Vancouver is not intuitively associated with water availability concerns, managing water quantity and quality in the region is an ongoing challenge in and outside times of drought; particularly in the agricultural sector–a primary water consumer.

Poor or absent regulation and monitoring of groundwater and surface water use in agriculture severely limits the capacity to assess water reserves and consumption and strategically manage water resources in times of water stress. This creates uncertainty regarding future water availability and risk within the agricultural sector.

The Water Sustainability Act, coming into force in 2016, aims to address this concern by instating groundwater licensing systems as well as regulations to reserve water for agricultural lands. Improving our understanding of the irrigation demand for agricultural production is a crucial step toward strategically managing the water resources upon which the agricultural industry depends.

This investigation aims to address this concern by using the Agricultural Water Demand Model for Metro Vancouver (AWDM) as a comparative assessment tool. The AWDM is used to investigate irrigation demand within Metro Vancouver’s Agricultural Land Reserve in order to inform policy makers with regards to water management.
