Collaborative Monitoring of Production and Costs of Timber Harvest Operations in the Brazilian Amazon Ecology and Society
Pokorny, Benno; University of Freiburg; benno.pokorny@waldbau.uni-freiburg.de.
Timber companies and policy makers in the Brazilian Amazon urgently need financial information on forest management. Results from a few experiments, case studies, and surveys have been groundbreaking, but are insufficient. A strategic partnership between timber companies and research organizations is needed to generate additional information. This paper presents a tool for monitoring production and costs of forest operations to facilitate such collaboration. The tool provides useful information for companies and, at the same time, generates reliable data for research. Selected results are presented on production, capacity, and costs to demonstrate the usefulness of the information that can be generated. These results are based on the first 2 years of...

Lake Restoration in Terms of Ecological Resilience: a Numerical Study of Biomanipulations under Bistable Conditions Ecology and Society
Amemiya, Takashi; Yokohama National University; amemiyat@ynu.ac.jp; Enomoto, Takatoshi; Yokohama National University; eno-bitz@ezweb.ne.jp; Rossberg, A. G.; Yokohama National University; axel@rossberg.net; Takamura, Noriko; National Institute for Environmental Studies; noriko-t@nies.go.jp; Itoh, Kiminori; Yokohama National University; itohkimi@ynu.ac.jp.
An abstract version of the comprehensive aquatic simulation model (CASM) is found to exhibit bistability under intermediate loading of nutrient input, supporting the alternative-stable-states theory and field observations for shallow lakes. Our simulations of biomanipulations under the bistable conditions reveal that a reduction in the abundance of zooplanktivorous fish cannot switch the system from a turbid to a clear state. Rather, a direct reduction of phytoplankton and detritus was found to be most effective to make this switch in the present model. These results imply that multiple manipulations may be effective for practical restorations of lakes. We discuss the present results of biomanipulations in terms of ecological resilience in multivariable...

Restoring Riparian Ecosystems: The Challenge of Accommodating Variability and Designing Restoration Trajectories Ecology and Society
Hughes, Francine M. R; Anglia Polytechnic University; f.hughes@apu.ac.uk; Colston, Adrian; Wicken Fen National Nature Reserve; adrian.colston@nationaltrust.org.uk; Mountford, J. Owen; NERC Centre for Ecology and Hydrology; om@ceh.ac.uk.
Flood disturbance processes play a key role in the functioning of riparian ecosystems and in the maintenance of biodiversity along river corridors. As a result, riparian ecosystems can be described as mobile habitat mosaics characterized by variability and unpredictability. Any river restoration initiative should aim to mimic these attributes. This paper suggests that there needs to be an increased institutional capacity to accept some levels of both variability and unpredictability in the ecological outcomes of river restoration projects. Restoration projects have frequently used some form of historical or contemporary reference system to define objectives and to help in the evaluation process. Using these reference systems can give a false sense of the...

A Diagrammatic Approach to Understanding Complex Eco-Social Interactions in Kathmandu, Nepal Ecology and Society
Neudoerffer, R. Cynthia; University of Guelph; rneudoer@uoguelph.ca; Waltner-Toews, David; University of Guelph; dwaltner@uoguelph.ca; Kay, James J.; Deceased 05/30/ 2004. Faculty of Environmental Studies, University of Waterloo;; Joshi, D. D.; NZFHRC;; Tamang, Mukta S.; SAGUN;.
As part of developing an international network of community-based ecosystem approaches to health, a project was undertaken in a densely populated and socio-economically diverse area of Kathmandu, Nepal. Drawing on hundreds of pages of narrative reports based on surveys, interviews, secondary data, and focus groups by trained Nepalese facilitators, the authors created systemic depictions of relationships between multiple stakeholder groups, ecosystem health, and human health. These were then combined to examine interactions among stakeholders, activities, concerns, perceived needs, and resource states (ecosystem health indicators). These qualitative models have provided useful heuristics for both community members and research scholars to understand the...

Applying Retrospective Demographic Models to Assess Sustainable Use: the Maya Management of Xa’an Palms Ecology and Society
Xa’an palm (Sabal yapa) has been used to thatch traditional Maya houses for over 3000 years. In the Yucatan Peninsula, this palm has been introduced to pasturelands, maize fields (milpas), and homegardens. These and other traditional management systems are usually believed to be sustainable, but there is as yet little evidence to support this hypothesis. Demographic models have been used for this purpose, mainly focusing on population growth rate (λ). So far, retrospective analysis has not been applied, even though it examines how changes in the the life cycle of a species, caused by different management regimes, affect its λ. In this study, we assess whether ecologically sustainable use of xa’an occurs in...

Integrating Sacred Knowledge for Conservation: Cultures and Landscapes in Southwest China Ecology and Society

China is undergoing economic growth and expansion to a free market economy at a scale and pace that are unprecedented in human history. This is placing great pressure on the country’s environment and cultural diversity. This paper examines a number of case histories in China, focusing on the culturally varied and ecologically diverse southwest region of the country. We show how developments in recent Chinese history have devalued and in some cases eliminated indigenous knowledge and practices in the quest to strengthen the centralized state. Despite these changes, more than 30 ethnic minorities live in southwest China. For generations these peoples have maintained landscapes through traditional land use and cultural practices. This indigenous...

Identifying Areas for Field Conservation of Forages in Latin American Disturbed Environments Ecology and Society
Peters, Michael; CIAT (International Center for Tropical Agriculture); m.peters-ciat@cgiar.org; Hyman, Glenn; CIAT (International Center for Tropical Agriculture); g.hyman@cgiar.org; Jones, Peter; CIAT (International Center for Tropical Agriculture); p.jones@cgiar.org.
This paper uses the spatial analysis tools DIVA and FloraMap to identify potential areas for the in situ conservation of a set of 10 forage species. We introduce the idea of roadside verges as conservation areas and discuss the risks and opportunities of two potential scenarios for conservation. These are the introduction of mass reservoirs outside of the original areas of collection and conservation inside the area of origin. Four potential areas for in situ conservation in Latin America are identified. Although more detailed studies using remote sensing, soil information, and field reconnaissance will be necessary for a final assessment of the suggested areas as field conservation sites, we discuss the possibilities of establishing low-maintenance...

A Perspective on the Evolution of e-Dialogues Concerning Interdisciplinary Research on Sustainable Development in Canada Ecology and Society
Dale, Ann; Royal Roads University; ann.dale@royalroads.ca.
Sustainable development research is inherently interdisciplinary; it requires the conscious search for unifying concepts that foster and reinforce understanding across disciplines. In addition, the number of sectors and actors involved in potential solutions requires a multistakeholder approach to decision making. The challenge of sustainable development research increasingly presents itself as a problem-solving activity. It involves producing useful knowledge through applied research. It is normative and not value-free. It involves complex issues of polity and culture. Thus, sustainable development research needs novel methods for research, for bringing together expertise that crosses disciplines and sectors, and for informing policy development. It also...
