Aligning Economic and Ecological Priorities: Conflicts, Complementarities, and Regulatory Frictions
Four key policy challenges, framed here as dichotomies, are commonly associated with attempts to improve the use of natural resources in the socioecological commons. These dichotomies present tradeoffs when addressing market failures and in general seem to suggest the need to settle for second-best outcomes rather than first-best outcomes identified in stylized models. Citing examples, we argue...

متن کاملMulti-Attribute Modelling of Economic and Ecological Impacts of Cropping Systems
Modelling of economic and ecological impacts of genetically modified crops is a demanding task. We present some preliminary attempts made for the purpose of the ECOGEN project “Soil ecological and economic evaluation of genetically modified crops”. One of the goals of the project is to develop a computer-based decision support system for the assessment of economic and ecological impacts of usin...
متن کاملMulti-objective optimization shapes ecological variation.
Ecological systems contain a huge amount of quantitative variation between and within species and locations, which makes it difficult to obtain unambiguous verification of theoretical predictions. Ordinary experiments consider just a few explanatory factors and are prone to providing oversimplified answers because they ignore the complexity of the factors that underlie variation. We used multi-...
متن کاملPeriodic solutions in modelling lagoon ecological interactions.
In this paper we present and analyze a nutrient-oxygen-phytoplankton-zooplankton mathematical model simulating lagoon ecological interactions. We obtain sufficient conditions, based on principal eigenvalue criteria -- for the existence of periodic solutions. A decoupled model which arises in the high nutrient regime is then considered in further detail for gathering some explicit conditions on ...
