Economic Analysis
of Invasive Species
introduction to
the training course
why the economics of invasives?
• issues associated with biological invasions have traditionally been
seen as responsibility of biologists
• yet invasive species are fundamentally an economic problem
– in terms of their causes, effects and remedies
• most invasions can be linked to the intended or unintended
consequences of economic activities
• the major (although not only) reason that invasives are considered
a problem by human beings is because they ultimately impact on
economic systems and undermine human wellbeing
• is now widely recognised that economics is to do with much more
than just understanding the costs of invasives - also concerns
causes, links between human behaviour and natural processes,
and finding solutions
2
Economic Analysis of Invasive Species
why the course?
• despite growing recognition by the scientific community of the need for
economics, the application of economic approaches and tools to
invasives remains a recent innovation
• most literature deals with the economic costs of invasions, and with
case studies carried out in North America and Europe
• although is now widely acknowledged that economic analysis and the
use of economic instruments are key to dealing with the problems
associated with biological invasions, there remains little guidance as
to how economic approaches and tools should be applied in practice
• invasive species have many unique and unusual characteristics which
set them apart from other environmental and land use issues,
meaning that conventional economics models don’t always apply

objectives of the course
• to solicit expert input and review of GISP
economic framework and tools for analysing and
addressing invasive species
• to build capacity and awareness among
economists and scientists to identify, understand,
and manage economic aspects of invasive
species

Economic Analysis of Invasive Species
the project
• Building Capacity in Africa for
Economic Analysis of the
Threats Posed by Invasive
Alien Species
– development of training
materials
– delivery of training course
• implemented by IUCN and
CABI under GISP
• funded by the World BankNetherlands Partnership
Programme

Economic Analysis of Invasive Species
the toolkit
• provides a clear, user-friendly
guide to the application of
economic approaches and tools
to invasive species
• employs a modular approach,
works through iterative steps to
identify, understand, address
and manage economic aspects
of invasive species
• targeted primarily at
economists, can also guide
scientists who are working on
invasive species management
6
Economic Analysis of Invasive Species
the workbook
• provides case studies of the
economic impact of invasive
alien species in Africa:
– Nile tilapia (Oreochromis
niloticus) - Uganda
– Water hyacinth (Eichhornia
crassipes) - Central African
Republic & South Africa
– Larger grain borer
(Prostephanus truncatus) Benin & Ghana
– Parthenium weed (Parthenium
hysterophorus) - South Africa
– Triffid weed (Chromolaena
odorata) - South Africa

Wrap-up and closing
“rules of the game”
• sessions are intended to be as interactive as
possible
• the participants in this course are all experienced
planners, researchers and analysts: everybody
has valuable knowledge and expertise to share
• participants are encouraged to comment, ask
questions, share experiences, and to provide their
own suggestions and insights
