Do Pesticide Hazards to Human Health and Beneficial Insects Cause or Result from IPM Adoption? Mixed Messages from Farmer Field Schools in Nicaragua AgEcon
Labarta, Ricardo A.; Swinton, Scott M..
This paper analyzes the interaction between farmer training in pest management and effects on acute pesticide poisoning and populations of beneficial insects in Nicaragua. Using farm level data from Nicaraguan bean growers, including graduates of Farmer Field Schools (FFS), other integrated pest management (IPM) outreach methods, and farmers without exposure to IPM, we found that small farmers are influenced by pesticide-related acute illness experiences when adopting IPM practices and making decisions about pesticide use. However, exposure to IPM extension programs failed to reduce the use of highly toxic pesticides and increased the number of self-reported acute illness symptoms during the most recent bean crop season. IPM training did result in...

Ecological Role of Submarine Canyons and Need for Canyon Conservation: A Review ArchiMer
Fernandez-arcaya, Ulla; Ramirez-llodra, Eva; Aguzzi, Jacopo; Allcock, A. Louise; Davies, Jaime S.; Dissanayake, Awantha; Harris, Peter; Howell, Kerry; Huvenne, Veerle A.i.; Macmillan-lawler, Miles; Martín, Jacobo; Menot, Lenaick; Nizinski, Martha; Puig, Pere; Rowden, Ashley A.; Sanchez, Florence; Van Den Beld, Inge.
Submarine canyons are major geomorphic features of continental margins around the world. Several recent multidisciplinary projects focused on the study of canyons have considerably increased our understanding of their ecological role, the goods, and services they provide to human populations, and the impacts that human activities have on their overall ecological condition. Pressures from human activities include fishing, dumping of land-based mine tailings, and oil and gas extraction. Moreover, hydrodynamic processes of canyons enhance the down-canyon transport of litter. The effects of climate change may modify the intensity of currents. This potential hydrographic change is predicted to impact the structure and functioning of canyon communities as well...

Self-Organized Governance Networks for Ecosystem Management: Who Is Accountable? Ecology and Society
Hahn, Thomas; Stockholm Resilience Centre, Stockholm University ; thomas.hahn@stockholmresilience.su.se.
Governance networks play an increasingly important role in ecosystem management. The collaboration within these governance networks can be formalized or informal, top-down or bottom-up, and designed or self-organized. Informal self-organized governance networks may increase legitimacy if a variety of stakeholders are involved, but at the same time, accountability becomes blurred when decisions are taken. Basically, democratic accountability refers to ways in which citizens can control their government and the mechanisms for doing so. Scholars in ecosystem management are generally positive to policy/governance networks and emphasize its potential for enhancing social learning, adaptability, and resilience in social-ecological systems. Political scientists,...

The Native Oyster Restoration Alliance (NORA) and the Berlin Oyster Recommendation: bringing back a key ecosystem engineer by developing and supporting best practice in Europe ArchiMer
Pogoda, Bernadette; Brown, Janet; Hancock, Boze; Preston, Joanne; Pouvreau, Stephane; Kamermans, Pauline; Sanderson, William; Von Nordheim, Henning.
Efforts to restore the native oyster Ostrea edulis and its associated habitats are gaining momentum across Europe. Several projects are currently running or being planned. To maximize the success of these, it is crucial to draw on existing knowledge and experience in order to design, plan and implement restoration activities in a sustainable and constructive approach. For the development of best practice recommendations and to promote multidimensional knowledge and technology exchange, the Native Oyster Restoration Alliance (NORA) was formed by partners from science, technology, nature conservation, consultancies, commercial producers and policy-makers. The NORA network will enhance scientific and practical progress in flat oyster restoration, such as in...

The Relevance of Local Participatory Scenario Planning for Ecosystem Management Policies in the Basque Country, Northern Spain Ecology and Society
Palacios-Agundez, Igone; Plant Biology and Ecology Department, University of the Basque Country UPV/EHU; igone.palacios@ehu.es; Casado-Arzuaga, Izaskun; Plant Biology and Ecology Department, University of the Basque Country UPV/EHU; Izaskun.casado@ehu.es; Madariaga, Iosu; Environment Department, County Council of Biscay; Plant Biology and Ecology Department, University of the Basque Country UPV/EHU; iosu.madariaga@bizkaia.net; Onaindia, Miren; Plant Biology and Ecology Department, University of the Basque Country UPV/EHU; miren.onaindia@ehu.es.
As part of the Millennium Ecosystem Assessment in Biscay, Basque Country, we described scenarios for Biscay through 2050 in an integrated and participatory way by downscaling the Millennium Ecosystem Assessment (MA) global scenarios, analyzed how ecosystem services and human well-being might change in a range of plausible futures, identified management strategies for the territory through a backcasting process, and explored the relevance of scenarios to policy making. Our intention was to strengthen the link to policy making and to achieve a real implementation of our research results in ecosystem management policies. We also aimed to provide more insights on how large-scale scenario developments can be translated to the local level. In doing so, we...

Trade-offs in ecosystem services and varying stakeholder preferences: evaluating conflicts, obstacles, and opportunities Ecology and Society
King, Elizabeth; Odum School of Ecology, University of Georgia; Warnell School of Forestry and Natural Resources, University of Georgia; egking@uga.edu; Cavender-Bares, Jeannine; Department of Ecology, Evolution and Behavior, University of Minnesota; Institute on Environment, University of Minnesota; cavender@umn.edu; Polasky, Stephen; Department of Applied Economics, University of Minnesota; Department of Ecology, Evolution and Behavior, University of Minnesota; Institute on Environment, University of Minnesota; polasky@umn.edu.
In efforts to increase human well-being while maintaining the natural systems and processes upon which we depend, navigating the trade-offs that can arise between different ecosystem services is a profound challenge. We evaluated a recently developed simple analytic framework for assessing ecosystem service trade-offs, which characterizes such trade-offs in terms of their underlying biophysical constraints as well as divergences in stakeholders’ values for the services in question. Through a workshop and subsequent discussions, we identified four different types of challenging situations under which the framework allows important insights to clarify the nature of stakeholder conflicts, obstacles to promoting more sustainable outcomes, and...

Uncertainty in Discount Models and Environmental Accounting Ecology and Society
Ludwig, Donald; University of British Columbia; Ludwig@math.ubc.ca; Brock, William A.; University of Wisconsin-Madison; WBrock@ssc.wisc.edu; Carpenter, Stephen R; University of Wisconsin-Madison; srcarpen@wisc.edu.
Cost-benefit analysis (CBA) is controversial for environmental issues, but is nevertheless employed by many governments and private organizations for making environmental decisions. Controversy centers on the practice of economic discounting in CBA for decisions that have substantial long-term consequences, as do most environmental decisions. Customarily, economic discounting has been calculated at a constant exponential rate, a practice that weights the present heavily in comparison with the future. Recent analyses of economic data show that the assumption of constant exponential discounting should be modified to take into account large uncertainties in long-term discount rates. A proper treatment of this uncertainty requires that we consider returns...

Variance as a Leading Indicator of Regime Shift in Ecosystem Services Ecology and Society
Brock, William A; University of Wisconsin-Madison; WBrock@ssc.wisc.edu; Carpenter, Stephen R; University of Wisconsin-Madison; srcarpen@wisc.edu.
Many environmental conflicts involve pollutants such as greenhouse gas emissions that are dispersed through space and cause losses of ecosystem services. As pollutant emissions rise in one place, a spatial cascade of declining ecosystem services can spread across a larger landscape because of the dispersion of the pollutant. This paper considers the problem of anticipating such spatial regime shifts by monitoring time series of the pollutant or associated ecosystem services. Using such data, it is possible to construct indicators that rise sharply in advance of regime shifts. Specifically, the maximum eigenvalue of the variance-covariance matrix of the multivariate time series of pollutants and ecosystem services rises prior to the regime shift. No...
