This paper illustrates the use of dual/adaptive control methods to compare passive and active adaptive management decisions in the context of an ecosystem with a threshold effect. Using discrete-time dynamic programming techniques, we model optimal phosphorus loadings under both uncertainty...

The paradigm of adaptive natural resource management (AM), in which experiments are used to learn about uncertain aspects of natural systems, is gaining prominence as the preferred technique for administration of large-scale environmental projects. To date, however, tools consistent with...

Recently many state and federal agencies in the U.S. have embraced an ecosystems management approach to environmental protection and regulation. This approach requires a high degree of cooperation between natural and social scientists to translate policy objectives into research hypotheses,...

The Fitzgerald River National Park is one of the world’s 25 biological hotspots, containing many endemic flora and fauna species. Its unique biodiversity is being threatened by the introduced root pathogen, Phytophthora cinnamomi. We evaluate the cost-effectiveness of strategies to manage...

This paper adopts a real options framework to evaluate the cost-effectiveness of four types of subsidies that aim to encourage a socially desirable land use under return uncertainties and costly reversibility of land use change. We first present a land conversion model to show how the subsidies...

Agricultural production is facing high requirements on nutrient runoff reduction. Furthermore, the reductions should by done efficiently. For instance, the European Water Framework Directive calls for cost-effectiveness from schemes of measures to fulfill the target of good water quality in...

Este artigo tem como objetivo abordar os SAF’s no contexto da NEI, identificando e descrevendo variáveis com maior motricidade e dependência, que restringem o desempenho dessas atividades no Estado de Rondônia. SAF’s são formas de uso da terra onde componentes florestais são associados...

This paper explores the likely impact of emissions trading design on transaction costs. Transaction costs include both the costs for the private sector to comply with the scheme rules and the costs of scheme administration. In economic theory transaction costs are often assumed to be zero. But...

Marine protected areas have been advocated as a useful tool in fisheries management. However, as protected areas they are a ‘blunt’ tool to manage fishery operations; in the sense that they do not alter the incentives of individual fishers, the outcomes from protected area creation are...
