Government agencies lack robust modelling tools to manage the spread of invasive alien species (IAS). In this paper, we combine optimal control and simulation methods with biological invasion spread theory to estimate the type of optimal policy and switching point of control efforts against a...

Invasive organisms are an environmental threat imposing major economic impacts on agriculture, human health, and the value of the natural environment. Significant efforts have been put into quarantine to prevent, detect and control invasive organisms and food contaminants. The increasing volumes...

Identifying the optimal switching point between different invasive alien species (IAS) management policies is a very complex task and policy makers are in need of modelling tools to assist them. In this paper we develop an optimal control bioeconomic model to estimate the type of optimal policy...

The risk of non-indigenous pests entering theUK via international trade in fresh produce isincreasing. Suppliers of fresh produce to UK and EUmultiple retailers are utilising new procurement areasfor fresh produce importation to reduce their costs ofproduction. The objective of this paper is to...

A major problem facing the Seychelles islands is the decline in the quality and the value of marine protected areas (MPAs). Economic valuation can help guide policy makers to understand the value of marine resources and the cost of neglecting MPAs by expressing the value of their goods and...

We develop an agent-based model integrated with a spatial stochastic simulation harmful non-indigenous species (NIS) spread model in which farmers have learning and imitation capabilities. The model is applied to the western corn rootworm (WCR) invasion in the UK. The invasion is never...
