Ecosystem approaches to natural resource management are seen as a way to provide better outcomes for ecosystems and for people, yet the nature and strength of interactions among ecosystem components is usually unknown. Here we characterize the economic benefits of ecological knowledge through a simple model of fisheries that target a predator (piscivore) and its prey. We solve for the management (harvest) trajectory that maximizes net present value (NPV) for different ecological interactions and initial conditions that represent different levels of exploitation history. Optimal management trajectories generally approached similar harvest levels, but the pathways toward those levels varied considerably by ecological scenario. Application of the wrong harvest trajectory, which would happen if one type of ecological interaction were assumed but in fact another were occurring, generally led to only modest reductions in NPV. However, the risks were not equal across fleets: risks of incurring large losses of NPV and missing management targets were much higher in the fishery targeting piscivores, especially when piscivores were heavily depleted. Our findings suggest that the ecosystem approach might provide the greatest benefits when used to identify system states where management performs poorly with imperfect knowledge of system linkages so that management strategies can be adopted to avoid those states.

Integrated Water Resource Management

A systems, holistic, or ecosystem approach is often advocated for water management, and has led to the emergence of integrated water resource management, or IWRM. Such an approach can be interpreted as ‘comprehensive’ or ‘integrated’, and analysts, planners, and managers need to understand the difference. Edge or boundary problems always are encountered when applying a holistic approach, and design of institutional arrangements cannot eliminate these problems but can minimize them. IWRM often does not have a statutory basis, which can lead to implementation challenges. By linking IWRM to land-use planning and official plans at the local level, IWRM can be given credibility, as well as be systematically connected to land-based issues.

Abstract The ecosystem approach emerged in the international environmental realm to promote equity and justice for both people and nature. It provides a set of mechanisms, including equitable benefit sharing; conservation and sustainable use; adaptive management; and participatory practices. This article explores how the ecosystem approach that is used in natural resource management shares synergies with notions of environmental justice, including distributional justice, procedural justice and justice-as-recognition. It also explores how the ecosystem approach responds to two additional principles of environmental justice that are specific to environmental disciplines, namely, intergenerational equity and the precautionary principle. The article illustrates the complementarity between the ecosystem approach and environmental justice through practical examples and argues that environmental justice can be promoted by utilizing the ecosystem approach as a vehicle for policy-makers.
