Unpacking the nexus in a changing world – the relationship between biosecurity, trade, health and environment 

ABSTRACT

The long-term trend of increasing volume and speed of movement of plants and plant material traded from an increasing variety of sources increases the chances of exotic pests arriving with imported goods and travellers, as well as by natural spread. The GB plant biosecurity strategy ensures activity is directed at priority pests and pathways and is informed by comprehensive risk assessment, which includes pest risk analysis, pathway analysis and trade intelligence plant pathology, population dynamics, and epidemiology, as well as social sciences to understand the values at risk. Responding effectively to new and emerging threats requires resilience, capability and preparedness to respond flexibly to new and emerging threats and everyone with an interest in plants must share responsibility for managing risks.

I will describe the drivers of biosecurity threats and the interactions between them; explain how commodity trading systems are managed to reduce risks, how factors such as farming practices, climate change and pressure on ecosystems and ecosystem services increase the risk from pest and disease outbreaks and examples of how good practices reduce risks.
