Resilience of local food systems and links to food security - A review of some important concepts in the context of COVID-19 and other shocks.

ABSTRACT: The objective of this review is to explore and discuss the concept of local food system resilience in light of the disruptions brought to those systems by the 2020 COVID-19 pandemic. The discussion, which focuses on low and middle income countries, considers also the other shocks and stressors that generally affect local food systems and their actors in those countries (weather-related, economic, political or social disturbances). The review of existing (mainly grey or media-based) accounts on COVID-19 suggests that, with the exception of those who lost members of their family to the virus, as per June 2020 the main impact of the pandemic derives mainly from the lockdown and mobility restrictions imposed by national/local governments, and the consequence that the subsequent loss of income and purchasing power has on people's food security, in particular the poor. The paper then uses the most prominent advances made recently in the literature on household resilience in the context of food security and humanitarian crises to identify a series of lessons that can be used to improve our understanding of food system resilience and its link to food security in the context of the COVID-19 crisis and other shocks. Those lessons include principles about the measurement of food system resilience and suggestions about the types of interventions that could potentially strengthen the abilities of actors (including policy makers) to respond more appropriately to adverse events affecting food systems in the future.

Project description:Resilience, defined as the ability of a system to adapt in the presence of a disruptive event, has been of great interest with food systems for some time now. The goal of this research was to build understanding about resilient food systems that will withstand and recover from disruptions in a way that ensures a sufficient supply of food for all. In large, developed countries such as the USA and Canada, the food supply chain relies on a complex web of interconnected systems, such as water and energy systems, and food production and distribution are still very labor-intensive. Thanks to economies of scale and effective use of limited resources, potential cost savings support a push towards a more centralized system. However, distributed systems tend to be more resilient. Although distributed production systems may not be economically justifiable than centralized ones, they may provide a more resilient alternative. This study focused on the supply-side aspects of the food system and the food system's water, energy, and workforce disruptions to be considered for the resilience assessment for the USA, with an example for the state of Texas. After the degree of centralization (DoC) was calculated, the resilience of a food system was measured. Next, the relationship between labor intensity and production of six major food groups was formulated. The example for Texas showed that the decentralization of food systems will improve their resilience in responding to energy and water disruptions. A 40 percent reduction in water supply could decrease the food system performance by 28%. A negative correlation was found between the resilience and DoC for energy disruption scenarios. A 40 percent reduction in energy supply could decrease the food system performance by 34%. In contrast, achieving a more resilient food system in responding to labor shortage supports a push towards a more centralized system the decentralization of food systems can in fact, improve their resilience in responding to disruptions in the energy and water inputs. In contrast, achieving a more resilient food system in responding to labor shortage supports a push towards a more centralized system.Supplementary informationThe online version contains supplementary material available at 10.1007/s12571-022-01321-9.
