Our resource-use dynamics have contributed significantly to the improvement in global material standards of living through the provisioning of essential societal services. Nonetheless, these dynamics have also impacted on the already limited natural resource-base of the Earth system on which we depend. Moreover, the characteristics of a global self-perpetuating resource-use linearity, the growing demand for finite raw materials, the high waste generation that remains unrecovered, and the increasing negative effects of climate change further exacerbate the Earth system’s vulnerabilities and exposure to risks. As such, the resource-use dynamics is posited as an important example of complex systems in need for better understanding, particularly in advancing towards sustainability and build system’s resilience. For resource-stressed settings like small island nations, the analysis of these complex systems is not only crucial, but urgent. Small Island Developing States are often characterized by sustainability challenges like limited resource-bases, reduced waste absorption capacity, a strong dependency on external resources to meet their basic needs, geographic isolation from markets which impact connectivity and resource supply, and natural and built environment that is progressively been threatened by the negative effects of climate change, which amplify the pre-existing vulnerabilities and risks for these territories. Thus, dealing with sustainability would require a deeper understanding of the interactions and trade-offs between the resource-use dynamics and the influences that internal/external factors like climate change have over these. By doing so, the system will have the ability to both contribute to global environment change, but also determine their own vulnerability or resilience to those changes. This thesis analyzes resource-use dynamics from a socio-metabolic research perspective in the context of small islands to enhance resource security and build system’s resilience, by looking into the way in which natural resources are interconnected, influenced, and managed. The analysis is spread across three main empirical Chapters, each of which contribute to advancing the arguments that arise from this work. First, in Chapter 3, the thesis analyzes the shifting resource-baselines of water, energy, and food, emphasizing the intra- and interconnected nature between essential resources and socio-metabolic risk, which builds the foundations for deeper analysis on current and future sustainability in small islands. Then, in Chapter 4, the thesis analyzes and identifies the size and make-up of material and energy flows specific to an individual case study, bringing important quantitative and qualitative insights on the potentials that reconfigured resource-use patterns may offer to minimizing or reducing socio-metabolic risk in small islands. Next, in Chapter 5, the thesis analyzes the role that critical material stocks play in driving resource-use and in furthering sustainable development, emphasizing climate change adaptation strategies to build system’s resilience. The overall framework of this thesis has demonstrated how a better understanding of resource-use dynamics may offer an opportunity to achieve resource security and self-reliance as a resilience building measure in the island context. Finally, this thesis encourages for the development and application of holistic and long-term resource management strategies through inclusive, climate and nature-based solutions that consider the trade-offs and synergies between different resource-use dynamics.

<sec><title>Introduction</title><p>Small island developing states (SIDS) are a diverse group of coastal and tropical island countries primarily located in the Caribbean and Pacific. SIDS share unique social, economic, and environmental vulnerabilities, high dependency on food imports, and susceptibility to inadequate, unhealthy diets, with high burdens of two or more types of malnutrition. Our objective was to examine trends in food availability, imports, local production, and risks of non-communicable diseases (NCDs) in three SIDS: Haiti, Saint Vincent and the Grenadines (SVG) and Fiji.</p></sec><sec><title>Methods</title><p>Data on food availability, imports, exports, and production was extracted from the Food and Agriculture Organization Database (FAOSTAT), and on overweight, obesity and diabetes prevalence from the NCD Risk Factor Collaboration database (NCD-RisC) from 1980 to 2018. Data were collated, graphed, and used to calculate import dependency ratios (IDRs) using Excel and R software.</p></sec><sec><title>Results</title><p>Between 1980 and 2018, the availability of calories per capita per day has risen in Fiji and SVG by over 500, to around 3000. In Haiti, the increase is around 200, to a level of 2,200 in 2018, and in all three settings, &gt; 10% of calories in 2018 came from sugar. In Fiji and Haiti, the availability of fruit and vegetables is &lt;400 g per person per day (the minimum intake recommended by WHO). Between 1980 and 2010, both Fiji and SVG experienced high IDRs: around 80% (Fiji) and 65% (SVG). In Haiti, IDR has more than doubled since 1980, to around 30%. The prevalence of obesity (BMI &gt; 30 Kg/m²) has increased since 1980 (by 126% to 800%) and is substantially higher in women. In the most recent data for Fiji, an estimated 35% of women are obese (24% men); in SVG, 30% women (15% men); and in Haiti, 26% women (15% men).</p></sec><sec><title>Conclusion</title><p>The increase in per capita availability of calories, which has taken place since 1980, is concurrent with an increase in IDR, a loss of local food, and increases in obesity prevalence. These findings highlight the importance of further research to understand the drivers of food supply transformations, and to influence improving nutrition, through production, availability, and consumption of nutritious local foods.</p></sec>

The multi-hazard vulnerability of Small Island Developing States in the Caribbean has underpinned the repeated saga of destructive natural and anthropogenic events that have disrupted land, livelihoods, the economy, and society over the past several decades. Preparedness and response have been the focus of national governments and regional entities and the repeated battering calls into question the concept of recovery and ‘building back better’. This paper examines the concept of recovery and ‘building back better’ in the context of the Caribbean, paying particular attention to the experience of the selected countries of Antigua and Barbuda, the Bahamas, Dominica, Guyana, Jamaica, and Saint Vincent and the Grenadines. These nations have recently been impacted by different disasters, ranging from storms to earthquakes to volcanic eruptions. This paper also explores the similarities among the recommendations concerning recovery needs, presenting key insights into suggested approaches for an inclusive people-centred recovery process that ‘builds back better’.

The Developing Organizational Capacity for Ecosystem Stewardship and Livelihoods in Caribbean Small Scale Fisheries ( StewardFish ) project recognized that there were a number of challenges hindering the engagement of fisherfolk and their organizations in the sustainable management of fisheries in the Caribbean region, including limited capacity of fisherfolk organizations to participate effectively in fisheries governance; insufficient capacity and knowledge of ecosystem stewardship practices for fisheries sustainability among fisherfolk ; inadequate public awareness of ecosystem approaches to support best practices and ensure compliance; inadequate documentation of successful experiences and practices for sustainable fisheries livelihood strategies; and inadequate management and collaboration mechanisms to support fisherfolk leaders in monitoring and evaluating projects. In addressing these constraints, the project supported the implementation of the ten year Strategic Action Programme (SAP) for the Sustainable Management of the Shared Living Marine Resources of the Caribbean and North Brazil Shelf Large Marine Ecosystems (CLME+) in Antigua and Barbuda, Barbados, Belize, Guyana, Jamaica, Saint Lucia, and Saint Vincent and the Grenadines by empowering fisherfolk throughout fisheries value chains to engage in resource management, decision making processes and sustainable livelihoods, with strengthened institutional support at all levels.
