Following the devastating droughts of the 1930’s, various tools have been developed to reduce the impact of drought on Canadian agricultural production. The most important ones are: increased economic diversification, improved dryland management practices by farmers, and well-developed government assistance programs. Procedures such as drought monitoring, modeling and remote sensing were also implemented for early drought detection. Models and indices based on estimation of available soil moisture, water deficit probabilities, irrigation requirements and crop water needs were developed to monitor drought and assess its impact. Different production and management systems, such as the flexible cropping concept, were proposed to farmers to assist in reducing drought-related losses.
