‘Power with’ and ‘power to’ in environmental politics and the transition to sustainability

Scholars of environmental politics demand serious reform of international governance and institutions to protect planet Earth. There is therefore an urgent need to discuss what causes change and gridlock in environmental politics. Serious reform is inextricably tied up with questions of power. The diversity with which studies on environmental politics understand power is exposed through three ideal type concepts: power with (learning and cooperation), power to (resistance and empowerment) and power over (coercion and manipulation). So far, scholars have mainly used analysis of coercive power (over) to explain gridlock in environmental politics; also needed is explicit acknowledgement of coaction and individual agency that can enable transition to more sustainable societies.     

Canada's Model Forests 20 years on: towards forest and community sustainability?

We review how Canadian Model Forests pursued forest and community sustainability over the course of two decades (1992–2012). Given its roots in the forest industry and forest science, Model Forest programming initially faced some challenges in pursuing the socio‐economic dimensions of sustainable forest management (SFM) in order to fulfil mandated community sustainability objectives. This was due, in part, to how objectives, stakeholders, and expertise were brought together to develop SFM. The programme helped to define sustainability and the SFM paradigm, advance forest science and social research, and bring together a mix of usually adversarial partners in the name of innovation. Ultimately, the termination of federal programming was linked to high‐level policy shifts, yet difficulty in delivering on the socio‐economic dimensions of SFM during a period of forest sector and community crisis was also a factor.     

Learning for sustainability through CIDA's “Community-based pest management in Central American agriculture” project: a deliberative,experiential and iterative process

Community-based approaches to environmental management provide opportunities for public engagement in local decision-making processes. This qualitative case study examines learning as resulted from participation in CIDA's “Community-based pest management in Central American agriculture” project. Outcomes include learning about alternative farming practices, human and natural environments, and safer pesticide use. Many participants learnt how to work more effectively with rural communities. For some, this changed their perspective about life and their role in society. Activities that fostered learning outcomes, including sustainability-related outcomes, were: planning and implementing project activities, experimenting on farm demonstration plots, participating in outreach workshops, and students doing rural practica. The learning process, involving international university collaborators and rural participants, is analyzed particularly as it relates to cultural context, collective action, and sustainability. Findings affirm that how the public participates in environmental management decisions influences the breadth and depth of learning outcomes; practical and policy implications are discussed.     

Managing stormwater for urban sustainability: an evaluation of local comprehensive plans in the Chesapeake Bay watershed region

This study uses a developed plan coding protocol in evaluating the quality of 76 comprehensive plans to examine whether local comprehensive plans have adequately integrated the concepts of sustainable stormwater management. The Chesapeake Bay watershed was chosen for the investigation because degraded stormwater runoff from nearby urban and suburban jurisdictions have critically polluted the watershed. The findings indicate that the majority of local governments have not sufficiently incorporated the sustainable stormwater management principles into their comprehensive plans. Five plan components (factual basis, goals and objectives, inter-organizational cooperation, policies, tools and strategies, and implementation) appear weak in realizing the concepts. The current study concludes by providing policy implications and recommendations to increase awareness and understanding of sustainable stormwater management concepts and to produce better implementation plans that integrate stormwater, ecosystem, and environmental planning comprehensively.     

Discourses on sustainable forest management and effects of Natura 2000: a case study of Catalonia,NE Spain

This study analyzed discourses influencing the meaning of Sustainable Forest Management in Catalonia (Spain) and the effects of the European Natura 2000 policy on these discourses. It focused on the Montseny area and on the Administration and Practitioner stakeholder groups. Based on literature review and interviews, we found six discourses influencing the meanings of Sustainable Forest Management. Two of these discourses underwent changes due to the effects of Natura 2000 implementation while the others did not, showing the substantial role played by local elements and actors in shaping the discursive framework of Sustainable Forest Management. Based on empirical findings, the study provided conclusions valid at European level: (1) implementing Natura 2000 does not mean revolutionizing local nature conservation systems, but rather adapting them to European requirements; (2) in order to increase local policy impact, the implementation of European environmental policies needs to be backed up by economic compensation of local actors.     

Policy Characterization of Ecosystem management

This paper provides a comparison of ecosystem management (EM) to the traditional regulatory management approach and outlines the characteristics of EM from a policy perspective, defining the conditions under which this management tool can be successfully implemented. Ecosystem management is a collaborative and integrative tool focused on balancing societal needs, economic growth, and environmental protection to ensure the long-term ecological integrity of a particular ecosystem. The characteristics of this particular tool include: (1) its holistic approach to environmental problems; (2) its integration of values (economic, social, and environmental) through a collaborative, multi-partner, decision making structure; (3) its reliance on science to guide decisions and set boundaries; and (4) its ability to learn from the implementation of decisions (adaptive management). Examples are draw from Environment Canada's various regional ecosystem initiatives.     

Predicted effects of prescribed burning and harvesting on forest recovery and sustainability in southwest Georgia, USA

A model-based analysis of the effect of prescribed burning and forest thinning or clear-cutting on stand recovery and sustainability was conducted at Fort Benning, GA, in the southeastern USA. Two experiments were performed with the model. In the first experiment, forest recovery from degraded soils was predicted for 100 years with or without prescribed burning. In the second experiment simulations began with 100 years of predicted stand growth, then forest sustainability was predicted for an additional 100 years under different combinations of prescribed burning and forest harvesting. Three levels of fire intensity (low, medium, and high), that corresponded to 17%, 33%, and 50% consumption of the forest floor C stock by fire, were evaluated at 1-, 2-, and 3-year fire return intervals. Relative to the control (no fire), prescribed burning with a 2- or 3-year return interval caused only a small reduction in predicted steady state soil C stocks (< or =25%) and had no effect on steady state tree wood biomass, regardless of fire intensity. Annual high intensity burns did adversely impact forest recovery and sustainability (after harvesting) on less sandy soils, but not on more sandy soils that had greater N availability. Higher intensity and frequency of ground fires increased the chance that tree biomass would not return to pre-harvest levels. Soil N limitation was indicated as the cause of unsustainable forests when prescribed burns were too frequent or too intense to permit stand recovery.     

Exploring changes in Ecuadorian land use for food production and their effects on natural resources

A model is used for the dynamic and spatially explicit exploration of near future agricultural land-use changes. In a case study for Ecuador, different plausible scenarios are formulated, taking into account possible developments in national food demand until the year 2010. The protection of nature parks and restrictions due to land degradation are evaluated with respect to their possible spatial impacts on the land-use change dynamics within the country. Under the assumptions of the demand scenarios, agricultural land-use expands significantly, resulting in more use of land in existing agricultural areas and frontier-type expansion into relatively undisturbed natural areas. The patterns of change depend on the increase in demand, competition between land-use types, changes in driving factors of land use, and the area and characteristics of land that is excluded from agricultural use. The modelled land-use dynamics are related to their possible impacts on the natural resource base, specifically soil fertility. The results indicate potential negative effects of land-use changes on the soil nutrient balance and biodiversity. It is argued that spatial and temporal quantification of land-use dynamics at the landscape level can support research and policies aimed at understanding the driving factors of land-use change and the behaviour of complex agro-ecosystems under changing conditions at different scales. In this way, issues dealing with sustainable food production and the management of the natural resource base can be addressed in a more integrated and quantitative manner.     

Justifying Sustainability

In the framework of ethical social choice theory, sustainability is justified by efficiency and equity as ethical axioms. These axioms correspond to the Suppes–Sen grading principle. In technologies that are productive in a certain sense, the set of Suppes–Sen maximal utility paths is shown to equal the set of non-decreasing and efficient paths. Since any such path is sustainable, efficiency and equity can thus be used to deem any unsustainable path as ethically unacceptable. This finding is contrasted with results that seem to indicate that an infinite number of generations cannot be treated equally.
