Can the Caribbean localize its food system?: Evidence from biomass flow accounting

Abstract

Small island economies are highly dependent on food imports. Self‐sufficiency through food localization is therefore often advocated. Can a small Caribbean island nation localize its food system? To answer this question, we conducted socio‐metabolic research on four Caribbean nations: Barbados, Dominica, Grenada, and Jamaica. Derived indicators from a diachronic biomass flow accounting from 1961 to 2019 suggest a declining trend in local food production for all cases. While in Barbados and Jamaica this decline already began in the 1960s, for Dominica and Grenada, this did not start until the late 1970s–1980s. The physical trade balance of biomass is similar across all cases: from net exporters at the start of the study period to net importers as countries developed, albeit at different time periods. By disaggregating biomass flow data to crop level, Barbados and Jamaica indicate a trend that is moving away from food localization, while Dominica and Grenada appear to be modestly moving toward localization in recent years. Given the many resource security challenges small island economies face, this study provides a biophysical perspective to the Caribbean's food security debate and questions the extent to which food localization is possible in a small island context, and whether other strategies are urgently needed.

The global atlas of edible insects: analysis of diversity and commonality contributing to food systems and sustainability

“…South America featured Hymenoptera (139), Coleoptera (75), Orthoptera (23), Lepidoptera (17), and Isoptera (15) as its predominant orders. Consumption pattern in Oceania region was characterised by Coleoptera (29), Lepidoptera (28), Hemiptera (16), Hymenoptera (14), and Orthoptera (7). These findings underscore the regional variations in edible insect preferences and highlight the significance of insect orders in shaping dietary choices across continents.…”

The role of supply chains for the sustainability transformation of global food systems: A large‐scale, systematic review of food cold chains

“…Seuring (2004) points out that IE's key distinctive feature when compared to other environmental management approaches is its regionality and geographical approach. Geographic variations and case‐specific conditions profoundly shape the nature and strength of the linkages between industrial, social, economic, and ecological systems (Chandrakumar et al., 2019; Jensen et al., 2011), the type of impacts they have (Jensen, 2016), and sustainability goals they need to serve primarily (Rahman et al., 2022). This principle of context specificity is salient for the case of global food supply chains as food often passes through regions with highly different socio‐economic conditions (Chandrakumar et al., 2019; Gold et al., 2017).…”

Can a small island nation build resilience? The significance of resource‐use patterns and socio‐metabolic risks in The Bahamas

“…Previous research has demonstrated the value of material flow analysis (MFA) as an innovative means of measuring levels of socioeconomic metabolism in the context of small islands. Most SMR focuses on inflows (Bahers et al., 2022; Chertow et al., 2020; Eisenhut, 2009; Krausmann et al., 2014; Rahman et al., 2022; Singh et al., 2001), very few on biophysical stocks (Bradshaw et al., 2020; Noll et al., 2019; Symmes et al., 20190) and outflows (Eckelman et al., 2014; Elgie et al., 2021; Mohammadi et al., 2021), however only one uses a mass‐balanced approach to explore the potential for a “circular economy” in an island context (Noll et al., 2021).…”
