Drought in agriculture

Please see the Quick guide to drought resources (PDF, 244.4KB), which provides information and guidance to help producers prepare for, and manage drought. 

Key drought management tips (PDF, 391KB)  assists irrigated crop producers to effectively plan and manage during drought conditions.  Learn how to make the most efficient use of limited irrigation supplies by planning how you manage during drought conditions.

Managing forage crops effectively during drought conditions requires specific strategies to optimize water use and maintain crop yields. Below are key resources for irrigation and forage management:

• Forage crops and irrigation management (PDF, 386KB): Learn key points on forage crops and effective water use
• Alternate forage crops when irrigation water is limited (PDF, 580KB): When irrigation water is limited due to drought conditions, producers may need to change their cropping program to get the highest yields possible from limited water
• Irrigated alfalfa management under drought conditions (PDF, 391KB): The right management of limited water supplies can mitigate negative impacts of drought on alfalfa yield and quality
• Managing irrigated forage crops during drought (PDF, 437KB): Why plan for drought if you irrigate? Unfortunately, drought can affect irrigated crop production, although with less frequency and impact than dryland production
• Pasture and hay rejuvenation options (PDF, 234KB): Outlines steps to maximize the potential for successful rejuvenation of forage and pasture following drought conditions

Prolonged drought can place a strain on the water resources available to producers and may leave livestock with poor quality water, resulting in lower weight gains, sickness, and leading to herd reduction or movement.

The Livestock Drought Management Guide (PDF, 2 MB) focuses on livestock feeding, forage crop considerations and economics decisions and includes suggested strategies for producers working through drought conditions. It is applicable to all livestock. Please note the interactive spreadsheets mentioned in the Guide will be posted here coming soon. If you would like to request a copy, please contact AgriServiceBC (AgriServiceBC@gov.bc.ca).

When irrigation water is limited due to drought, a decision needs to be made to irrigate all acres with reduced water, or part of the acreage with the full water required, leaving some acres as dryland. Read Irrigation decisions with limited water (PDF, 358KB) for more information when making these decisions.

More irrigation resources can be found on our Irrigation and Farm water supply, storage and conservation pages.

Storing water during wetter times of the year is a useful drought preparedness strategy. British Columbia farm water dugouts (PDF, 3.1MB) and Guidance on farm water storage (PDF, 1.3MB) offer helpful information to guide you through these topics.

Water storage is often a feasible option even in places where accessing a water licence for use during the growing season may be difficult. It is important to note  that most dugouts require a water licence under the Water Sustainability Act, with some exceptions. Storing water typically occurs when water resources are more readily available, such as during freshet.

Stay informed about drought and drought conditions across the province. Visit the Drought information webpage for general information about drought and to learn more about temporary protection orders.

The B.C. Drought Information Portal is a key provincial resource for up-to-date drought information, offering a provincial drought map of current drought levels and resources to help the public understand provincial drought conditions and regulatory actions.

The B.C. Agriculture Water Calculator helps agriculture water users in British Columbia estimate the annual irrigation or livestock water demand for a farm. Irrigation water demand estimates are made based on climate and the geographic location of the farm, as well as its soil type, crop type and type of irrigation. Livestock water demand estimates are made for a given number and type of animals.

The B.C. Agriculture Water Calculator now also features a Dugout calculator, designed to help producers plan for their water storage needs. This feature allows users to calculate appropriate dugout dimensions based on their target storage capacity of rainwater, groundwater or surface water. 

The B.C. Irrigation Water Use Calculator is a water management tool that can be used to track actual irrigation water use without the need to purchase a flow measuring device. Users can enter their irrigation system run times or pump energy consumption, and the tool will calculate the actual annual irrigation water use to help track water usage and manage drought. A printable report can be generated for record keeping purposes.

Producers rely heavily on weather conditions to be able to make decisions for their farm every day.  To help make these decisions, producers can access weather data from the Farmwest website, which collects data from over 200 weather stations in B.C., from provincial, federal, municipal, and private agricultural networks.

The data collected from weather stations (such as temperature, precipitation, and relative humidity) are fed into the Farmwest Evapotranspiration (ET) calculator to calculate ET rates in the selected location. ET is the moisture lost from soil and plant surfaces through evaporation and from plant through transpiration based on weather conditions. The water lost is replenished by rainfall and/or irrigation.

The Agricultural Irrigation Scheduling Calculator is an essential tool for drought preparedness. Using near real-time weather data from Farmwest and five-day forecasts from Environment and Climate Change Canada, it recommends irrigation schedules tailored to a specific farm. By inputting details about their crops, soil, and irrigation system, and selecting their nearest weather station, producers receive a customized irrigation schedule for the next five days. This helps producers optimize water use, conserve resources, and improve crop and soil health. 

See the Agriculture Irrigation Scheduling Calculator (PDF, 1.5 MB) factsheet for more information and the Irrigation Industry Association of British Columbia (IIABC) website for user guides.

The Agriculture Water Demand Model was developed to provide current and future agriculture water demand estimates for use by water resource planners and decision makers.

The intent of the model was to help fulfil the province’s commitment under the Living Water Smart water plan to reserve water for agricultural lands. Existing reports are available at the Agriculture Water Demand Model webpage.

The model calculates water use on a property-by-property basis and adds the calculated water for each together to obtain a total for the entire basin or sub-basin. Crop, irrigation system type, soils and climate data are used to calculate the water demand.
