"The risk of non-indigenous plant pests entering the UK via international trade in fresh produce is increasing. The objective of this article is to identify existing and emerging supply sources for UK fresh produce importers and examine the extent to which they could provide invasion pathways....

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...

The risk of non-indigenous pests entering the UK via international trade in fresh produce is increasing. Suppliers of fresh produce to UK and EU multiple retailers are utilising new procurement areas for fresh produce importation to reduce their costs of production. The objective of this paper...

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...

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 economic value of biological collections in three major botanic gardens in Australia was estimated using the Travel-Cost (TC) and Contingent Valuation (CV) methods. The study used truncated count data models to control for the non-negative integer and truncation properties of the number of...
