TOWARDS SUSTAINABLE FOOD SYSTEMS: A HOLISTIC, INTERDISCIPLINARY AND SYSTEMIC APPROACH

Abstract

One of the biggest challenges facing humanity is achieving sustainable foodsecurity in the face of population growth, resource scarcity, ecosystem degradationand climate change. Transitioning towards sustainable food systems (SFS) is amust for achieving sustainable development. This review paper highlights the needto adopt a holistic, multidimensional, interdisciplinary and systemic approach forbetter understanding food systems, which is a prerequisite for fostering transitiontowards sustainability. A better understanding of food systems meanscomprehending issues at play from ‘farm to fork’ i.e. production (crop, animal,seafood), processing, trade and distribution, and consumption. For gaining a fullawareness also cross-cutting issues such as gender, innovation and technologyshould be considered. Such a deep knowledge and consequent corrective actionsare crucial to address the multiple challenges and dysfunctions of the current globalfood system such as food insecurity, obesity, food waste, climate change,biodiversity loss, land degradation, water depletion, deforestation, marketconcentration and food heritage erosion. It is fundamental to foster transitiontowards sustainable and resilient food systems to achieve sustainable food andnutrition security for present and future generations. All dimensions (environment,economy, society and culture, nutrition and health) of food sustainability should betackled while considering policy and governance. Different food consumption andproduction models can help speeding up journey towards sustainability. Theseinclude, inter alia, organic agriculture and different alternative food systemsallowing to link consumption and production such as urban agriculture,community-supported agriculture and short food chains. While the challenge istitanic, there is a menu of options that can be jointly used to foster shift towardsSFS such as sustainable and eco-functional intensification, sustainable diets, foodloss and waste reduction. Nevertheless, a holistic and systemic approach isnecessary to develop a systems thinking for generating interdisciplinary knowledgeneeded to support transition towards sustainable food systems.
