Article: Simulations of agents in social networks harvesting a resource
[show abstract] [hide abstract]
ABSTRACT: Managing natural resources increasingly requires an understanding not only of the underlying resource dynamics but also the dynamics of human use. In an agent-based model, we simulate agents harvesting a renewable resource, and examine the effect of agents in different social networks on their ability to exploit the resource under different levels of uncertainty. When uncertainty in the resource is high, under assumed conditions, ordered social networks can exploit the resources better by passing information among the agents than when individuals act independently of each other. The more highly connected random networks, however, leads to lower aggregate harvests. When a single “skilled” agent is able to obtain a greater harvest than the others, a hierarchical performance among agents results, with those connected directly to the “skilled” agent obtaining higher harvests than those that are not.Ecological Modelling. -
Article: An agent-based modelling approach to evaluation of multiple-use management strategies for coastal marine ecosystems
[show abstract] [hide abstract]
ABSTRACT: The general objective of the multiple-use management strategy evaluation (MSE) framework is to develop and demonstrate practical science-based methods that support, under existing statutory arrangements, integrated regional planning and management of coastal and marine ecosystems. In the present paper multiple-use MSE is focused on four sectors: oil and gas, conservation, fisheries, and urban and industrial development. A selection of cross-sectoral development scenarios, management strategies and computer representations, provided by the relevant interest groups, is represented. These include prospective future sectoral activities and their impacts, and the sectoral response to alternative management policies and strategies. The agent-based modelling software InVitro is well placed for analysing prospective social and ecological impacts of multiple-use management strategies in a risk-assessment framework such as MSE. An illustrative example is provided to demonstrate the tradeoffs that can be recognised and quantified using the MSE framework. The example explores the implications of a change in management strategy that not only has a direct impact on the targeted sectors, but also indirect impacts, not all of which are to be expected.Mathematics and Computers in Simulation.
