Abstract

Abstract Background: Invasive species affect the social, economic and health aspects of many farmers and are known to cause major losses with considerable costs spent on management. Several international agreements recognise the threat caused by invasive species which signatories have an obligation to manage. This paper sets out a framework and method for assessing the performance and responsiveness of a country's invasive species system. The objective is to engage with key actors within an invasive species system using a participatory approach to determine the strengths, weaknesses and functioning of the invasive species system. The aim is to understand the system as it currently stands and to identify opportunities and challenges from various actor's perspectives. Method: The first step was to define an invasive species system and its component parts including the functions, expected outputs and contextual factors. Subsequently, a range of indicators and participatory tools were developed to measure system performance. The process includes a desk review, stakeholder workshop and key informant interviews. The approach was piloted in Kenya, but a revised approach, focussing on the desk review and key informant interviews, was used in Zambia. Results: Actors who are actively engaged in managing invasive species were identified and engaged in both Kenya and Zambia. The assessment process provided insights into the current functioning of the invasive species systems in both countries. A number of key challenges were identified relevant to both countries, for instance, the lack of finance, governance and leadership were identified as major barriers to effective system performance, alongside the lack of a central coordinating body to guide invasive species management. Conclusion: The systems approach developed helped in facilitating the engagement of key actors within a country's invasive species system. The actors performed a self-assessment of the current system status and determined what is required to move towards more effective management of invasive species. Participants responded positively to the framework and process developed, which contributed to developing ownership and clear steps forward towards a more pro-active, rather than reactive, approach in the management of invasive species.

Highlights

Invasive species affect the social, economic and health aspects of many farmers and are known to cause major losses with considerable costs spent on management
We identified the key actors in invasive species management delivery, what approaches are used, and what human and financial resources are available
The results report on the current state of the invasive species system using a revised approach in the absence of the stakeholder workshop

Summary

Introduction

Invasive species affect the social, economic and health aspects of many farmers and are known to cause major losses with considerable costs spent on management. Several international agreements recognise the threat caused by invasive species which signatories have an obligation to manage. Parties to the 1992 Convention on Biological Diversity (CBD) agree in Article 8 (h) to “prevent the introduction of, control or eradicate those alien species which threaten ecosystems, habitats or species” (UNEP, 2002). This means that signatories have a responsibility to manage invasive species, and in order to do that, countries first need to put the necessary capacity and an effective control structure in place
