A case study of the Convention on Biological Diversity and the Federated States of Micronesia.

The country faces a number of environmental challenges, not least of which is the loss of biodiversity upon which it relies for subsistence and economic development. The FSM is a signatory to the UN Convention on Biological Diversity (CBD) and must develop and deliver a National Biodiversity Strategy and Action Plan as a way of implementing the convention and protecting its biodiversity. For a SIDS like the FSM, being a party to the CBD presents a notable burden: fielding personnel to global meetings, crafting necessary policies and legislation and implementing such policies. This article explores the perceptions of what being a signatory to the CBD brings to those in countries such as the FSM who are responsible for, or involved in, developing and implementing biodiversity conservation policy and actions. It highlights specific perceived benefits and challenges, and considers these in relation to the status of biodiversity in the FSM today.

Introduction: A picture of a small island state The Federated States of Micronesia (FSM) is a country of 607 islands spread across almost 3 million km 2 of the tropical North-West Pacific (see Figure 1; also CIA, 2019; FSM PIO, 2011). Although the population of just over 100,000 has fallen somewhat recently, it is still predicted to grow to over 130,000 within the next 40 years (FSM Office of Statistics, Budget, Overseas Development Assistance and Compact Management, n.d.; UNDESA, 2017).
