| Severe depletion of many genetically distinct Pacific salmon populations has spawned a contentious debate over causation and the efficacy of proposed solutions. No doubt the precipitating factor was overharvesting of the commons beginning along the Northwest Coast around 1860. Yet, for millenia before that, a relatively dense population of Indian tribes managed salmon stocks that have since been characterized as “superabundant.” This study investigates how they avoided a tragedy of the commons, where in recent history, commercial ocean fishers guided by scientifically informed regulators, have repeatedly failed. Unlike commercial fishers, the tribes enjoyed exclusive rights to terminal fisheries enforced through rigorous reciprocity... |

| Agricultural intensification in rural areas of developing countries compromises the provision of ecosystem services. Social conflict arises among landholders with different preferences for ecosystem services and land-use practices in agricultural frontiers of the Argentine Dry Chaco. We explored policy and management options by assessing the actual and potential outcomes of alternative land-use systems and scenarios. We first constructed the efficiency frontier for avian habitat and agricultural productivity to analyze the combinations of ecosystem services that can be achieved under different land-use intensities. A nonlinear, concave efficiency frontier indicated opportunities to achieve large gains for production with small losses for conservation, for... |

| Environmental decision-makers are increasingly demanding detailed spatial coverages with high temporal frequency to assess trends and changes in the extent and condition of wetlands, species habitats, farmlands, forests, rangelands, soil, water, and vegetation. Dynamic land cover information can substantially meet these requirements. Access to satellite-based time series information provides an unprecedented opportunity to better focus natural resource management (NRM) in Australia. Opportunities include assessing the extent and condition of key assets, prioritizing investment in key localities and time periods, improving targeting of scarce public funding, and monitoring and evaluating the outcome of this investment to assist land managers in improving... |

| Volunteer water monitoring programs are one of the most popular forms of citizen science, but many face governmental funding cuts and other threats to their continuation. Alabama Water Watch (AWW) is such a program that for more than 20 years has had positive influences on ecosystems and society through environmental education, waterbody protection and restoration, and promotion of improved water policy. A temporal analysis of 15 program indicators revealed 4 phases of AWW that followed general patterns of organizational development. These included periods of rapid growth, cresting, moderate decline, and stabilization at a lower level of activity. Five factors influenced these trends: saturation of potential groups, loss of monitors from aging,... |

| Assessments of ecosystem services (ES), that aim at informing decisions on land management, are increasing in number around the globe. Despite selected success stories, evidence for ES information being used in decision making is weak, partly because ES assessments are found to fall short in targeting information needs by decision makers. To improve their applicability in practice, we compared existing concepts of ES assessments with focus on informing land use decisions and identified opportunities for enhancing the relevance of ES assessments for decision making. In a process of codesign, building on experience of four projects in Brazil, China, Madagascar, and Vietnam, we developed a step-wise approach for better targeting ES assessments toward... |

| In 2014, the Third International Conference on the resilience of social-ecological systems chose the theme “resilience and development: mobilizing for transformation.” The conference aimed specifically at fostering an encounter between the experiences and thinking focused on the issue of resilience through a social and ecological system perspective, and the experiences focused on the issue of resilience through a development perspective. In this perspectives piece, we reflect on the outcomes of the meeting and document the differences and similarities between the two perspectives as discussed during the conference, and identify bridging questions designed to guide future interactions. After the conference, we read the documents... |
