Despite all the effort that has gone into defining, researching and establishing best practices for cumulative effects assessment (CEA), understanding remains weak and practice wanting. At one extreme of implementation, CEA can be described as merely an irritant to the completion of a project-specific environmental assessment (EA). At the other extreme, the conceptual view is that all effects in EA should be deemed cumulative unless demonstrated otherwise. Our purpose here is to consider how we might reconceive CEA as a mindset that is at the heart of absolutely every assessment of valued ecosystem component (VEC) to ensure that we understand the relative contributions of various stressors and can decide when cumulative effects may foreclose future activities due to impacts on VECs. Conceptually, we ground the CEA mindset in the context of three lenses that must all be functioning and working together for the mindset to be operative: a technical lens; a law and policy lens; and a participatory lens. Our arguments are based on a review of the CEA, strategic effects assessment (SEA) and regional effects assessment literatures, an examination and consideration of Canadian EA and SEA case practice, and our combined professional experiences. Through using the Bay of Fundy in Canada as a case example, we establish the concept of the CEA mindset and an approach for moving forward with implementation.

This article investigates emerging governance arrangements at the intersection between forest management and climate policy. The authors deploy the symposium's three-dimensional framework to describe and evaluate developments within two distinct policy sectors (forestry/climate change adaptation and mitigation) at several levels of governance (bi-national, national, and sub-national) to explore the nature and operation of the emerging governance arrangements, and assessing and measuring change within these arrangements over time. Drawing on four contemporary case studies from the US and Canada, New Zealand, British Columbia and Alaska, the authors discern little evidence of a generalized, linear trend from 'government to governance'. Instead, they conclude, across institutional, political and regulatory dimensions of governance, a more variegated and diverse picture emerges. Their analysis also lends support for the Trubek and Trubek (2007) hypothesis that emerging governance arrangements typically interact with extant ones through modalities of rivalry, complementarity and transformation.

This article offers an overview of the two key outcomes of the 2015 Paris climate negotiations, the Paris cop decision, and the Paris Agreement. Collectively, they chart a new course for the un climate regime that started in earnest in Copenhagen in 2009. The Paris Agreement represents a path away from the top-down approach and rigid differentiation among parties reflected in the Kyoto Protocol, toward a bottom-up and flexible approach focused on collective long-term goals and principles. It represents an approach to reaching these long-term goals that is focused on self-differentiation, support, transparency, and review. The article highlights the key elements of the agreement reached in Paris, including its approach to mitigation, adaptation, loss and damage, finance, transparency, and compliance.
