Quantifying the impact of alien invasive species on ecosystem services is an essential step in developing effective practices and policy for invasive species management. Here we develop a stochastic bioeconomic model that enables the economic impact of an invasive pest to be estimated before its arrival, based on relatively poorly specified ecological and(More)
1206 13 MARCH 2015 • VOL 347 ISSUE 6227 sciencemag.org SCIENCE P ayments for Ecosystem Services (PES) mechanisms leverage economic and social incentives to shape how people influence natural processes and achieve conservation and sustainability goals. Beneficiaries of nature’s goods and services pay owners or stewards of ecosystems that produce those(More)
Benefit cost analysis is a tried and tested analytical framework that can clearly communicate likely net changes in producer welfare from investment decisions to diverse stakeholder audiences. However, in a plant biosecurity context, it is often difficult to predict policy benefits over time due to complex biophysical interactions between invasive species,(More)
Invasive species present significant threats to global agriculture, although how the magnitude and distribution of the threats vary between countries and regions remains unclear. Here, we present an analysis of almost 1,300 known invasive insect pests and pathogens, calculating the total potential cost of these species invading each of 124 countries of the(More)
This paper is motivated by the observation that there is a difference between the time paths of damage valuations for invasions which affect agricultural compared with environmental systems. In particular, unlike agricultural systems, social valuation of an environmental system is likely to be exponentially positively related to the extent of its(More)
Loss of area freedom from invasive alien species can have serious food security implications and place huge responsibility on incursion response managers. They make critical decisions despite profound uncertainty surrounding invasion ecology, surveillance and control technology effectiveness and human behaviour. We propose a spatially-explicit model that(More)
The hypothesis, derived from experience in Nova Scotia, that artificial pneumothorax, requiring repeated fluoroscopy of the chest, is associated with an increased risk of subsequent breast cancer was tested in Ontario by means of a retrospective cancer patient/control study using record linkage. Sanatorium patients treated by artificial pneumothorax were(More)
ABSTRACT Potato cyst nematodes (PCN) (Globodera spp.) are quarantine pests with serious potential economic consequences. Recent new detections in Australia, Canada, and the United States have focussed attention on the consequences of spread and economic justifications for alternative responses. Here, a full assessment of the economic impact of PCN spread(More)
Biosecurity agencies need robust bioeconomic tools to help inform policy and allocate scarce management resources. They need to estimate the potential for each invasive alien species (IAS) to create negative impacts, so that relative and absolute comparisons can be made. Using pine processionary moth (Thaumetopoea pityocampa sensu lato) as an example, these(More)
