Going beyond 'it depends:' the role of context in shaping participation in natural resource management

Public participation is increasingly advocated in natural resource management to meet a spectrum of instrumental to normative goals. However, the success of participation in achieving these goals is highly variable, depending on both societal and institutional contexts. Whether participation realises its benefits or succumbs to its pitfalls is shaped by dynamic interactions operating among three contextual dimensions: participatory rationales (instrumental to normative), institutional fit of different levels (types) of participation (information delivery to partnership to delegation), and social structures (such as cultural context, social capital and power distribution). Some levels of participation may support the existing power hierarchy, others benefit organized stakeholder groups and special interests, and still others foster deliberative democratic outcomes. We argue that wise choice of levels of participation in particular contexts shapes the balance of participation’s benefits and pitfalls

Interactions between changing climate and biodiversity: Shaping humanity's future

Scientists have known for more than a century aboutpotential human impacts on climate (1). In the last 30 y,estimates of these impacts have been confirmed andrefined through increasingly precise climate assess-ments (2). Other global-scale human impacts, includingland use change, overharvesting, air and water pollu-tion, and increased disease risk from antibiotic resis-tance, have risen to critical levels, seriously jeopardizingthe prospects that future generations can thrive (3–5).Earth has entered a stage characterized by humandomination of critical Earth system processes (6–8).Although the basic trajectories of these changes arewell known, many of the likely consequences areshrouded in uncertainty because of poorly understoodinteractions among these drivers of change and there-fore their effects on ecosystems and societies.Fil: Stuart Chapin III, F..

Reflections on Planning Education at UNC-Chapel Hill

As the Department of City and Regional Planning (DCRP) at the University of North Carolina at Chapel Hill nears its 50th anniversary, it is timely to look back on its origins and ponder how it came to be one of the leading schools of planning in the country. My reflections examine the first thirty years of the department. They describe DCRP's beginnings and identify some highlights of planning education and urban research at Chapel Hill, and conclude with a few observations on the key strengths of the department in this period

Urban Land Use Policy in an Era of Constraints

These are times of widespread interest in "land use." But as land use has gained currency, it has come to mean different things to different interest groups. To some, it has to do with national resource use—the use of land for agriculture, grazing, forestry, extraction, or wildlife sanctuaries. To others, it has to do with use of state resources—the seacoast, lake country, mountains, or other areas of critical environmental concern. And to still others, it refers to land development in the urban scene for industrial, business, residential, or other uses. There are both positive and negative associations with land use. To many, land use is a tangible reflection of economic vitality and strength; to others, it means problems or destructive tendencies in man's activities. One common denominator to these different perspectives is the interface between growth and finite resources—the need to come to terms with environmental overloads, energy resource shortages, and other resource problems that may adversely affect the economy and the well-being of millions of households. The seventies will undoubtedly be marked as a watershed, a time when Americans came to realize that many finite resources long taken for granted were after all limited, many of them nonrenewable or irreversibly damageable. In this essay, I shall be less concerned with this precarious balance as a problem than with governmental responses to this problem and how these impact on land use policies of local governments. Let me begin with the initiatives of the federal government and work downward to the local level

Changes in the surface energy budget after fire in boreal ecosystems of interior Alaska: An annual perspective

Understanding links between the disturbance regime and regional climate in boreal regions requires observations of the surface energy budget from ecosystems in various stages of secondary succession. While several studies have characterized fire‐induced differences in surface energy fluxes from boreal ecosystems during summer months, much less is known about these differences over the full annual cycle. Here we measured components of the surface energy budget (including both radiative and turbulent fluxes) at three sites from a fire chronosequence in interior Alaska for a 1‐year period. Our sites consisted of large burn scars resulting from fires in 1999, 1987, and ∼1920 (hereinafter referred to as the 3‐, 15‐, and 80‐year sites, respectively). Vegetation cover consisted primarily of bunch grasses at the 3‐year site, aspen and willow at the 15‐year site, and black spruce at the 80‐year site. Annual net radiation declined by 31% (17 W m^(−2)) for both the 3‐ and the 15‐year sites as compared with the 80‐year site (which had an annual mean of 55 W m^(−2)). Annual sensible heat fluxes were reduced by an even greater amount, by 55% at the 3‐year site and by 52% at the 15‐year site as compared with the 80‐year site (which had an annual mean of 21 W m^(−2)). Absolute differences between the postfire ecosystems and the mature black spruce forest for both net radiation and sensible heat fluxes were greatest during spring (because of differences in snow cover and surface albedo), substantial during summer and winter, and relatively small during fall. Fire‐induced disturbance also initially reduced annual evapotranspiration (ET). Annual ET decreased by 33% (99 mm yr^(−1)) at the 3‐year site as compared with the 80‐year site (which had an annual flux of 301 mm yr^(−1)). Annual ET at the 15‐year site (283 mm yr^(−1)) was approximately the same as that from the 80‐year site, even though the 15‐year site had substantially higher ET during July. Our study suggests that differences in annual ET between deciduous and conifer stands may be smaller than that inferred solely from summer observations. This study provides a direct means to validate land surface processes in global climate models attempting to capture vegetation‐climate feedbacks in northern terrestrial regions

Changing Forests in a Warming World

Severe fires can dramatically alter the future growth of a spruce forest. A severe fire is likely to change the forest to one dominated by broadleaf deciduous trees, especially in drier places.York's Knowledge Mobilization Unit provides services and funding for faculty, graduate students, and community organizations seeking to maximize the impact of academic research and expertise on public policy, social programming, and professional practice.

Changing Daily Wind Speeds on Alaska’s North Slope: Implications for Rural Hunting Opportunities

Because of their reliance on the harvest of fish and game, Alaskan rural communities have experienced a variety of impacts from climate change, the effects of which are amplified at high latitudes. We collaborated with hunters from the coastal community of Wainwright, Alaska, to document their observations of environmental change (e.g., sea ice, wind, temperature) and the implications of those changes for opportunities to hunt bowhead whale (Balaena mysticetus) during spring and caribou (Rangifer tarandus) during summer. We integrated hunter observations on wind with statistical analysis of daily wind speed data collected in the nearby community of Barrow, Alaska, between 1971 and 2010 to characterize changes in the number of days with suitable hunting conditions. Hunters in Wainwright currently observe fewer days than in previous decades with wind conditions suitable for safely hunting bowhead whales and caribou. The statistical analysis of wind speed data supported these conclusions and suggested that the annual windows of opportunity for hunting each species have decreased by up to seven days since 1971. This study demonstrates the potential power of collaboration between local communities and researchers to characterize the societal impacts of climate change. Continued collaborative research with residents of rural northern Alaskan communities could produce knowledge and develop tools to help rural Alaskans adapt to novel social-ecological conditions.Les collectivités rurales de l’Alaska dépendent de la récolte du poisson et du gibier et à ce titre, elles sont assujetties à une panoplie d’incidences découlant du changement climatique, dont les effets sont amplifiés en haute altitude. Grâce à l’aide des chasseurs de la collectivité côtière de Wainwright, en Alaska, nous avons consigné les observations de ces chasseurs relativement à l’évolution de l’environnement (en ce qui a trait, par exemple, à la glace de mer, au vent et aux températures) de même que les incidences de cette évolution sur les possibilités de chasse de la baleine boréale (Balaena mysticetus) au printemps, et du caribou (Rangifer tarandus) à l’été. Nous avons intégré les observations des chasseurs au sujet du vent à l’analyse statistique des données de la vitesse quotidienne du vent, données recueillies dans la localité avoisinante de Barrow, en Alaska, entre 1971 et 2010, afin de caractériser les changements quant au nombre de jours où les conditions de chasse sont convenables. Comparativement aux décennies précédentes, les chasseurs de Wainwright observent un moins grand nombre de jours, à l’heure actuelle, qu’au cours des décennies précédentes pendant lesquels le régime des vents se prête à la chasse sécuritaire de la baleine boréale et du caribou. L’analyse statistique des données de la vitesse du vent permet de soutenir ces conclusions et suggère qu’annuellement, la période pendant laquelle chacune de ces espèces peut faire l’objet de la chasse a diminué dans une mesure allant jusqu’à sept jours depuis 1971. Cette étude témoigne du pouvoir de collaboration qui pourrait exister entre les collectivités de la région et les chercheurs dans le but de caractériser les incidences du changement climatique sur la société. Les travaux de recherche en collaboration continue avec les habitants des collectivités rurales du nord de l’Alaska pourraient permettre de produire des connaissances et d’élaborer des outils qui aideraient les Alaskiens à s’adapter aux nouvelles conditions socioécologiques
