Tracking a Governance Transition: Identifying and Measuring Indicators of Social Forestry on the Willamette National Forest

Abstract

National Forests in the United States have undergone a spatially and temporally uneven governance transition in response to social and economic pressures and contemporary policy changes, with many national forest units moving from a wholly government-led “dominant federal” model to a more collaborative “social forestry” model in which nonfederal actors have greater influence and authority. Here we report on an effort to develop a suite of indicators designed to capture some of the most tangible elements of a transition from dominant federal to social forestry modes of governance. We pilot test these data on the Willamette National Forest using data from a variety of sources internal and external to the USDA Forest Service. We assess the suitability of these indicators for tracking governance transitions and discuss their applicability to other national forest units nationwide.     

Women in the Field: Critical Feminist Methodologies and Theoretical Perspectives*

Feminist scholars have traditionally emphasized the importance of incorporating “the everyday” worlds of women into the historically masculinist theoretical and empirical foundations of the social sciences. Such emphases have commonly resulted in smaller-scale research projects and more interactive kinds of research methods and methodologies. Feminist geographers have uniquely contributed to the body of feminist scholarship through drawing out the importance of place in everyday constructions of gender and, more recently, sexuality. Critical field-based research has therefore from the beginning been the mainstay of subdisciplinary research. Like the discipline as a whole, however, little explicit attention has been given in publications or pedagogically to the politics of fieldwork (including how a “field” is defined and the politics involved in choosing and working in a particular “field”) or the politics of representation (which includes considerations of the partiality of knowledge and how and to whom we represent our work, ourselves and others in various kinds of texts). These “Opening Remarks” show how these issues are addressed in the papers that follow and how feminist geography has much to contribute to critical analyses of global and multinational processes, including patriarchy, capitalism, and racism.     

“Ghana must Progress,but we are Really Suffering”: Bui Dam,Antipolitics Development,and the Livelihood Implications for Rural People

In late-2013, Bui Dam was commissioned on Ghana’s Black Volta River. The hydroelectric project inundated 444?km², flooding communities, forests, crops, and a national park. State elites promoted the dam through nationalistic discourses while simultaneously framing rural people responsible for accessing its trickle-down economic benefits. Drawing from critical development literature within a political ecology framework, this article examines tensions between discourses underpinning construction of Bui Dam and the lived experiences of rural people. Drawing from data collected in 82 interviews, the dam’s implications for resettlement, food security, mental health, agricultural production, and fishing livelihoods are detailed. I argue interlocking discourses, laws and processes—from eminent domain and compensation metrics to party politics—combined to work as an “antipolitics machine.” Hydroelectric development renders invisible structural processes shaping inequality and creates new injustices. As Bui Power Authority, the corporation managing the dam and surrounding land-uses has a new CEO, the article concludes with several practical suggestions for improving community members’ everyday lives.     

The dynamic neptunian ring arcs: evidence for a gradual disappearance of Liberté and resonant jump of courage

We present Adaptive Optics observations of Neptune's ring system at 1.6 and 2.2 μm, taken with the 10-m W.M. Keck II telescope in July 2002 and October 2003. We recovered the full Adams and Le Verrier rings for the first time since the Voyager era (1989), and show that the overall appearance of these rings did not change much, except for the ring arcs. Both the location and intensity of all arcs changed drastically relative to trailing arc Fraternité, which has a mean orbital motion of 820.1118 ± 0.0001 deg/day, equal to that of Nicholson et al.'s (1995, Icarus 113, 295-330) solution 2. Our data suggest that all arcs may have decayed over the last decade, while Liberté, in 2003, may be on the verge of disappearing completely. The observed changes in the relative intensities and locations of all arcs further indicate that material is migrating between resonance sites; leading arc Courage, for example, has jumped ∼8°, or, when adopting Namouni and Porco's (2002, Nature 417, 45-47) CER (corotation eccentricity resonance) theory, it advanced by one full corotation potential maximum. Overall, our observations reveal a system that is surprisingly dynamic, and no comprehensive theory exists as of yet that can explain all the observed intricacies.     

Dissolved organic carbon in pore waters from a hypersaline environment

Pore waters were collected from a sea-marginal, hypersaline pond in the Sinai and analyzed for dissolved organic carbon (DOC). The pore water DOC values ranged from 121 to 818 mg 1⁻¹ with maxima between 15 and 54 cm deep. These values are some of the highest observed from recent sediments and probably reflect production via abiotic as well as biotic sources.     

Flow and transport in channels with submerged vegetation

This paper reviews recent work on flow and transport in channels with submerged vegetation, including discussions of turbulence structure, mean velocity profiles, and dispersion. For submerged canopies of sufficient density, the dominant characteristic of the flow is the generation of a shear-layer at the top of the canopy. The shear-layer generates coherent vortices by Kelvin-Helmholtz (KH) instability. These vortices control the vertical exchange of mass and momentum, influencing both the mean velocity profile, as well as the turbulent diffusivity. For flexible canopies, the passage of the KH vortices generates a progressive wave along the canopy interface, termed monami. The KH vortices formed at the top of the canopy penetrate a distance δ _e into the canopy. This penetration scale segregates the canopy into an upper layer of rapid transport and a lower layer of slow transport. Flushing of the upper canopy is enhanced by the energetic shear-scale vortices. In the lower layer turbulence is limited to length-scales set by the stem geometry, and the resulting transport is significantly slower than that of the upper layer.     

Effect of ice sheet growth and melting on the slip evolution of thrust faults

Field investigations suggest that postglacial unloading and rebound led to the formation or re-activation of reverse faults even in continental shields like Scandinavia. Here we use finite-element models including a thrust fault embedded in a rheologically layered lithosphere to investigate its slip evolution during glacial loading and subsequent postglacial unloading. The model results show that the rate of thrusting decreases during the presence of an ice sheet and strongly increases during deglaciation. The magnitude of the slip acceleration is primarily controlled by the thickness of the ice sheet, the viscosity of the lithospheric layers and the long-term shortening rate. In contrast, the width of the ice sheet, the rate of deglaciation or the fault dip have an only minor influence on the slip evolution. In all experiments, the slip rate variations are caused by changes in the differential stress. The modelled deglaciation-induced slip acceleration agrees well with the occurrence of large earthquakes soon after the melting of the Fennoscandian ice sheet, which led to the formation of spectacular fault scarps in particular in the Lapland Fault Province. Furthermore, our model results support the idea that the low level of seismicity in currently glaciated regions like Greenland and Antarctica is caused by the presence of the ice sheets. Based on our models we expect that the decay of the Greenland and Antarctica ice sheets in the course of global warming will ultimately lead to an increase in earthquake frequency in these regions.     

Seismic activity related to the 2000 eruption of the Hekla volcano, Iceland

The 2000 Hekla eruption took place from February 26 to March 8. Its seismic expressions were a swarm of numerous small earthquakes related to its onset, and low-frequency volcanic tremor that continued throughout the eruption. A swarm of small earthquakes was observed some 80 min before the onset of the eruption, and the size of the events increased with time. Low-frequency volcanic tremor, with a characteristic frequency band of 0.5–1.5 Hz and dominant spectral peak(s) at 0.7–0.9 Hz, became visible at 18:19 GMT on February 26, marking the onset of the eruption. The tremor amplitude rose quickly and was very high in the beginning of the eruption. However, it soon began to decrease after about an hour. In general, the seismic activity related to the 2000 Hekla eruption was very similar to what was observed in the previous eruption in 1991. Based on knowledge gained from seismicity and strain observations from 1991, this was the first time that a Hekla eruption was predicted.Editorial responsibility: J Stix
