    Gaps in environmental and social evidence base are holding back strategic action on our national food system
    (Taylor and Francis Group on behalf of the Royal Society of New Zealand, 2025-07-03) Smith NW; McDowell RW; Smith C; Foster M; Eason C; Stephens M; McNabb WC
    While there is broad agreement on the challenges facing the Aotearoa New Zealand food system now and in the near future, there is less agreement on the action to be taken. Poor agreement is fuelled by gaps in both our scientific understanding of the food system and data to support our decision making, particularly in the environmental and social spaces. Filling these gaps and being transparent about scientific confidence in future predictions will strengthen the evidence base for action.

    Evolution of global food trade network and its effects on population nutritional status
    (Elsevier BV, 2023-06-03) Silvestrini MM; Smith NW; Sarti FM; Marangoni AG
    Changes in food systems during the last decades fostered the establishment of global food networks based on exchanges between countries with different income levels. Recent studies explored configuration and factors associated with trade networks of specific food items during limited periods; however, there is lack of evidence on evolution of trade networks of foods for human consumption and its potential effects on population nutritional status. We present the evolution of the global trade network of foods for human consumption from 1986 to 2020, according to country income level, and we explore potential effects of country network centrality and globalization processes on the prevalence of overweight and obesity. Results show intensification of international food trade and globalization processes in the period of analysis with implications for population nutritional status worldwide.

    Predictors of tree damage and survival in agroforests after major cyclone disturbance in Fiji
    (Springer Nature, 2024-03-12) McGuigan A; Tora M; Tikonavuli V; Ticktin T
    This study explores the resilience and damage dynamics of agroforests, a critically important yet understudied agroecological system, in the aftermath of Category-5 Cyclone Winston in Fiji. As agroforestry gains prominence globally as a versatile production system able to support agrobiodiversity and food security for climate resilience, understanding the characteristics that contribute to its resistance and resilience to disturbance becomes increasingly important. Here we examine the effects of individual and species-specific traits, and management (planted and fallow vs forest areas) on the probability of tree stem survival and damage, and discuss the resistant and resilient qualities of trees and management actions in these systems. We found that the probability of post-cyclone survival increased as a function of wood density, irrespective of management type. Damage severity increased with tree size (diameter at breast height). Some of the species with the highest wood density were native trees, emphasizing the role of native species in agroforests, and the value of agroforests to conservation. Overall, agroforest trees experienced relatively low stem mortality (12.2%), suggesting that these agroforests may resist extreme disturbances despite their potential vulnerabilities such as landscape edge effects and altered species compositions. Our study provides insight into the potential of agroforests as resilient agroecological systems capable of withstanding escalating cyclone intensities, and the role of effective management strategies for fostering resilience amid a rapidly changing climate.

    Viewpoint: The case for a six-dimensional food security framework
    (Elsevier Ltd, 2022-01-12) Clapp J; Moseley WG; Burlingame B; Termine P
    The definition of food security has evolved and changed over the past 50 years, including the introduction of the four commonly cited pillars of food security: availability, access, utilization, and stability, which have been important in shaping policy. In this article, we make the case that it is time for a formal update to our definition of food security to include two additional dimensions proposed by the High Level Panel of Experts on Food Security and Nutrition: agency and sustainability. We show that the impact of widening food system inequalities and growing awareness of the intricate connections between ecological systems and food systems highlight the importance of these additional dimensions to the concept. We further outline the ways in which international policy guidance on the right to food already implies both agency and sustainability alongside the more established four pillars, making it a logical next step to adopt a six dimensional framework for food security in both policy and scholarly settings. We also show that advances have already been made with respect to providing measurements of agency and sustainability as they relate to food insecurity.
