Title:
CLIMATE CHANGE AND POTATO (SOLANUM TUBEROSUM) GROWING POTENTIAL IN THE FAR NORTH OF ONTARIO, CANADA

Abstract:
Potatoes are an "entry level" cultivar with modest thermal requirements. Potato cultivation that has a scant history in Ontario's Far North may be able to contribute to the food security of the region in the unfolding decades of this century. The potential for growing potatoes (Solanum tuberosum) in Ontario's Far North is examined from current climate and future climate perspectives. Using two growing-degree day thresholds, the frost free period, and available climate data, the current climatic potential for growing potatoes at Moosonee, Fort Albany, Neskantaga (formerly Lansdowne House) and Kitchenuhmaykoosib Inninuwug (formerly Big Trout Lake) is assessed. Using climate change projections the future climatic potential for growing potatoes is assessed for these communities and for Peawanuck and Fort Severn until the end of the century. Moosonee, Fort Albany, Neskantaga and Kitchenuhmaykoosib Inninuwug had the requisite thermal conditions to grow potatoes at present. Using climate change projections for the region, Peawanuck will meet the potato growing threshold by the 2020s and Fort Severn will do so by the 2050s. Projected intensification and lengthening of the growing season in the region suggests that other more thermally intensive produce, in addition to potatoes, may be possible this century.
