Dynamics of Human-Natural Coupled Systems and the Management of Harmful Species

Adam Lampert

 

Abstract

The management of harmful species, including invasive species, pests, parasites, and diseases, is a major global challenge. Harmful species cause severe damages to ecosystems, agriculture, forestry, and human health. To manage harmful species, humans aim to prevent the establishment of the species and to eradicate or control those species populations that have already been established. One question is, therefore, how to combine the available tools and tactics to achieve these goals cost-effectively. Furthermore, the management of harmful species often requires cooperation among multiple agents, such as farmers, land‐owners, agencies, and countries. A second question is, therefore, which environmental policy would better incentivize the agents to cooperate. In my talk, I will present two models aiming to address each of these questions, with an emphasis on how the optimal treatment and policy depend on the biological and ecological characteristics of the harmful species. To address the first question, I will present a model that incorporates the natural dynamics of an invasive insect population and its response to three treatment tactics: pesticide application, sterile male release, and mating disruption. I will show that the combination of treatment tactics that are used should vary over time and depend on the density of the population. To address the second question, I will present a dynamic game-theoretic model and examine how a policymaker should allocate the treatment duties among the agents. I will show that, when a fast eradication is possible, the better policy would be to split and assign only one or a few agents to treat the species in a given location; but if the persistent control of the harmful species population at a low density is needed, the agents should work together in all the locations. These studies suggest that treatment strategies and policies should be developed in accordance with the biological and ecological characteristics of the target species.

 

Short Bio

Adam completed his Ph.D. at the Department of Physics of Complex Systems at the Weizmann Institute in 2012. He did a postdoc at the University of California at Davis between 2012 and 2015. Since 2015, he is a faculty member at Arizona State University. In his research, Adam uses mathematical modeling approaches to study how our society can sustainably manage our environment and our ecological systems. In particular, he uses optimal control and game theory to study situations where multiple agents, such as land-owners or countries, manage the same ecosystem. A major recent focus of his research has been on how to mitigate climate change as well as the accelerated infiltration of harmful species. Adam published his research in some of the top journals, including Science, PNAS, Nature Communications, and Ecology Letters.
