Quebec's forests represent 20% of Canadian forests and 2% of the world forests. Over the entire planet, forests play a major role in habitat preservation and in supplying goods and services to the population. However, climate change will have an impact on the forest through inter alia increased droughts, forest fires, warmer weather, and infestations. In this paper, we analyze the economic impact of climate change on the forest industry in Quebec over a 40-year period using a recursive dynamic computable general equilibrium model. We find that the climate change effects will be relatively weak on most macroeconomic variables as agents adjust their behavior over time and factors are reallocated across sectors. We find that climate change could generate losses in gross domestic product of up to Can$300 million (0.12% of gross domestic product) at the end of a 40-year period for Quebec's economy. However, we find relatively more important effects within the sectors of the forest industry, with losses ranging from 3% to 7.5%. [ABSTRACT FROM AUTHOR]

The Canadian Arctic is uniquely sensitive to climate change impacts, including rapidly warming temperatures, sea ice change, and permafrost degradation. Adaptation-including efforts to manage climate change risks, reduce damages, and take advantage of new opportunities-has been identified as a priority for policy action across government levels. However, our understanding of adaptation in the Canadian North is limited: Is adaptation taking place, to what stresses, and what does it look like? In this paper we answer these questions for the Inuit territory of Nunavut, systematically cataloguing and reviewing government-led adaptation programs and policies at community, territorial, and federal levels, drawing on publically available information. We documented a total of 700 discrete adaptation initiatives. The focus on adaptation to-date has primarily been at the groundwork level, aimed at informing and preparing for adaptation through impact assessments, adaptation planning exercises, and stakeholder engagement. Adaptation in Nunavut has been driven by cross-scale coordination and leadership from the territorial and federal government. Our study finds few examples of concrete actions for planned adaptation, such as changes to or creation of policies that enable adaptation, alterations to building codes and infrastructure design with changing geo-hazards, or enhanced disaster planning and emergency preparedness in light of projected impacts. This study indicates a need for formal adaptation plans for the Governments of Canada and Nunavut, emphasis on adaptation monitoring and evaluation, and a greater role of Inuit traditional knowledge and cultural values in adaptation policy.

The aim of this paper is to present approaches to optimize stand-level, short-rotation coppice management planning, taking into account uncertainty in stand growth due to climate change. The focus is on addressing growth uncertainty through a range of climate scenarios so that an adaptive capacity may be possible and the vulnerability of the stand to climate change may be reduced. The optimization encompasses finding both the harvest age in each cycle and the number of coppice cycles within a full rotation that maximize net present revenue. The innovation lies in the combination of the process-based model (Glob3PG) with two dynamic programming (DP) approaches. The former is able to project growth of eucalypt stands under climate change scenarios. The innovative approaches are thus influential to define the management policy (e.g., stool thinning, number of coppice cycles, and cycle length) that maximizes net present revenue taking into account uncertainty in forest growth due to climate change. In both approaches, the state of the system is defined by the number of years since plantation, whereas DP stages are defined by the cumulative number of harvests. The first approach proposes the optimal policy under each climate change scenario at each state. The second approach addresses further situations when the climate scenario is unknown at the beginning of the planning horizon. Both help address uncertainty in an adaptive framework, as a set of readily available options is proposed for each scenario. Results of an application to a typical Eucalyptus globulus Labill. stand in central Portugal are discussed. [ABSTRACT FROM AUTHOR]
