Rainwater Harvesting for Small-Scale Agriculture

Co-Directors, Point Roberts Homegrown Co-op

Although Vancouver’s water supply is plentiful, a growing population and a changing climate are increasing pressures on water resources to meet future demands. This, in turn, could have major impacts on agricultural production in British Columbia as peak water demand will coincide with drier and longer summers. Many urban/peri-urban farms are committed to sustainability, self-sufficiency, and environmentally sound practices however, given their limited funds, they are financially burdened by experimenting with alternative technologies and water resources.
The Homegrown Rainwater Calculator is a resource for small-scale, diversified farms and is designed for growers to determine the feasibility of a rainwater system at their site. This is done by calculating their current water requirements, the volume of water that can be captured and the approximate tank size needed to meet water demands. The model also allows the user to see how reliable their rainwater system may be in the future as weather patterns deviate from the norm.


Acadia and Andrew are Co-Directors of the Point Roberts Homegrown Co-op, a diverse, small-scale, organic market garden. The Co-op is dedicated to providing healthy, organic produce and education about sustainable food production.

Andrew studied Environmental and Industrial Labor history at Pitzer College, CA and is interested in agriculture as the primary nexus between humans and the natural environment, and the critical, yet often overlooked role agriculture plays at the center of issues of health, pollution, ecological degradation, political power and social justice. Acadia received her B.Sc. from Pitzer College specializing in ecology and how endemic plant communities recover from grazing. Her love of plants sparked her interest in local food systems and organic food production. In 2015, she completed the professional Master of Land and Water System (MLWS) program.

This event is jointly hosted by the Land and Water Systems and Soil Seminar series.
