Description

In forest mensuration, forest inventory and forest modeling, it is common to compare the agreement between two sets of quantitative measurements. One set could be from a commonly-accepted reference method, the other from a new or alternative method, device, or model. If the measurements are statistically the same or practically "close enough" to each other, the more complex, more destructive and/or costly method can be replaced by the simpler, less destructive and/or more efficient method. Traditional statistical approaches used for such comparisons based on bias, correlation coefficient, coefficient of determination and significance tests are inadequate and not really relevant for agreement analysis. Various agreement measures proposed for agreement analysis are also insufficient and not pertinent in many respects. An alternative approach based on the limits of agreement proposed by Bland and Altman (1986) is introduced and demonstrated in this study, along with the method...

Description

Highlights work done by the Alberta Phosphorus Watershed Project between 2013-2017. The purpose of the project was to determine if widespread adoption of agricultural beneficial management practices would improve water quality at the watershed scale, and to develop the Alberta Phosphorus Management Tool as a means to identify highest risks for phosphorous loss. Results are presented in a detailed technical science report and an overview and key findings fact sheet.

Description

In 2014, the Economics Branch of Alberta Agriculture and Forestry (AF) in collaboration with the Alberta Greenhouse Growers Association (AGGA) conducted a comprehensive survey to update the “Profile of the Greenhouse Industry in Alberta” 2010 report with 2014 data. The project was funded by Growing Forward 2, a federal-provincial-territorial initiative. The report provides current benchmark data on greenhouse crop operations in Alberta. This includes size, distribution in different regions within the province, heating systems, water and energy use trends, labour, as well as opportunities and issues related to financing, environment, business climate and regulation, competitiveness with imports, and other benchmarks and future trends.
