Quantifying the transient response of ecological-economic systems to perturbations
نویسنده
چکیده
Ecologists and economists are increasingly in agreement that ecological and economic systems are linked and that these actually should be viewed as one system. Perhaps because this recognition has been very recent, neither ecologists nor economists have studied the short-term behavior of jointly determined ecologicaleconomic systems that are subject to perturbations stemming from natural events and the continuance of economic activities. Consequently, the purpose of this paper is to construct a metric that can be used to quantify the transient response of ecological-economic systems to perturbations. This metric is a non-asymptotic measure of an ecological-economic system’s resilience. 2000 Elsevier Science Inc. All rights reserved.

Sensitivity analysis of reactive ecological dynamics.
Ecological systems with asymptotically stable equilibria may exhibit significant transient dynamics following perturbations. In some cases, these transient dynamics include the possibility of excursions away from the equilibrium before the eventual return; systems that exhibit such amplification of perturbations are called reactive. Reactivity is a common property of ecological systems, and the...
متن کاملReactivity and stability of large ecosystems
*Correspondence: Stefano Allesina, Department of Ecology and Evolution, University of Chicago, 1101 E. 57th, Chicago, IL 60637, USA e-mail: [email protected] The study of local stability has a long tradition in community ecology. Stability describes whether an ecological system will eventually return to its original steady state after being perturbed. More recently, the study of the transi...
متن کاملMeasure and comparison of economic, social and ecological sustainability of farming systems in the Marvdasht plain
Agricultural sustainability refers to the ability of a cropping system to produce, without causing irreversible damage tothe ecosystem. There is an increasing need to view cropping systems and identify management practices in a holisticindicator-based impact assessment. The main objective of this study was to compare and rank the cropping systems of theMarvdasht plain in Fars Province; in order...

متن کاملDynamic Harmonic Modeling and Analysis of VSC-HVDC Systems
Harmonics have become an important issue in modern power systems. The widespread penetration of non-linear loads to emerging power systems has turned power quality analysis into an important operation issue under both steady state and transient conditions. This paper employs a Dynamic Harmonic Domain (DHD) based framework for dynamic harmonic analysis of VSC-HVDC systems. These systems are wide...
