Small island developing states are often characterized as vulnerable owing to their unique geographies of smallness and remoteness, resource insecurity, and more recently from the impacts of climate change. These vulnerabilities are often manifested in resource insecurity, significant imports, poor waste management, and the inability to develop economies of scale. In effect, sustaining small islands in an era of global environmental change is a task both scholars and policy makers are increasingly grappling with. Can small islands be sustainable? This research examines the social metabolism of an island system, and introduces the concept of “socio-metabolic vulnerability”. As such, this research provides novel insights into the linkages between patterns of resource-use, systemic risks and vulnerability. Results from a local material and energy flow analysis (local-MEFA) for the island of Ndzuwani (Comoros) suggest a very low level of resource-use but at the same time heavy reliance on critical imports that cover vast distances, that are vulnerable to price and climate shocks. Informal activities in resource extraction play an important role in lending both vulnerability and resilience to Ndzuwani. This study adds to the scarce body of literature that argues that small island economies would need to leverage resource-use patterns to build system resilience, along with bold policies and institutions that support material circularity, engage communities and fosters frugal innovation.

The Caribbean region remains susceptible to an increasing frequency of natural disasters, rising international debt, out-migration, rapid urbanization, and high imports to meet basic needs. Food and nutrition insecurity persists in these small island states, with around 67.5% of the population living in moderate or severe food insecurity. Policy adjustments required to address the targets subsumed by the second sustainable development goal (SDG2 or Zero Hunger) are still at an infant stage. This research offers rigorous and up-to-date analyzes of the current status of Caribbean food policies and practices through a scoping review and expert interviews to answer the question, “What constraints and enablers impact the ability of small island states to achieve the Zero Hunger goal?”. A scoping review is performed following the relevant population, concept, and context (PCC) methodology by the Joanna Briggs Institute (JBI). Five major challenges and barriers are identified through the scoping review: (i) island geography, (ii) governance deficiencies, and (iii) institutional constraints, compounded by (iv) collaboration barriers, and (v) externally imposed impediments (including environmental and financial shocks). To address these challenges, synergistic linkages and restrictive connections have been recognized for SDG2 localization. It was concluded that three dimensions of food security (utilization, agency, and sustainability) are mainly overlooked, necessitating special attention and action. By identifying bridging institutions and engaging various actors in supporting shared rulemaking, power, conflict management, and knowledge-sharing among local, national, and regional policy actors, a polycentric governance system is recommended as a suitable mechanism to help islands move towards food security.
