In the context of climate change, many regions of the world are predicting large scale changes to traditional ways of life, caused at times by destructive events such as devastating natural forces such as rising sea level and desertification. However, some areas may stand to benefit, and the Yukon may be one of those places. I used a multicriteria evaluation (MCE) with the criteria of soil texture, proximity to water, proximity to roads, slope, and effective growing degree days (EGDD) to assess potential agricultural land in the Yukon. I recalculated the EGDD calues for 1990 from monthly mean temperatures and compared them to the EGDDs calculated from daily values, in order to determine whether an approximation using monthly mean temperatures was valid. I found that the monthly temperature based EGDD values were a close underestimate of the daily temperature based EGDD values. I used this knowledge to vary the EGDD values according to the predicted temperature changes in the Yukon, and compared the new areas of potential agricultural land to the current distribution of argicultural activities. There is a clear trend towards an increase in areas, but there are many aspects in which more detailed analysis would be requried for a thorough assessment of suitability.
