Integrating environmental and socio-economic indicators to explore the sustainability of food patterns and food security in Lebanon

Abstract

Food security is a complex issue whose comprehension requires multidisciplinary research exploring environmental, socio-economic, and policy aspects. World population is expected to continue increasing in the next decades. As a consequence, the global food demand is also expected to increase, exacerbating the contribution of food consumption and production patterns to environmental problems and climate change. In addition, the problem of socio-economic inequalities is also noteworthy, with a very high number of undernourished people at global level. Considering the complex nature of food security, the integration of environmental and socio-economic indicators is much needed for assessing its multiple dimensions. In this study, environmental and socio-economic indicators were assessed to explore the sustainability of food patterns and food security in Lebanon. Environmental indicators were calculated to assess the environmental costs and impacts of the Lebanese and refugee diets. All the environmental indicators calculated for the Lebanese diet resulted higher compared to the refugee diet. The overall contribution of the refugee diet to the investigated impact categories resulted in about 25%, confirming its significance in terms of direct and indirect natural resources consumption and environmental impacts. The socio-economic indicators showed that food security is a critical issue for the Lebanese population and, particularly, for the refugees living in Lebanon. In particular, 59% and 15% of Lebanese and refugee populations resulted having an adequate individual access to food. In conclusion, the outcomes of the study provide scientific information to support policy-makers and a benchmark for future studies aimed at improving food security in Lebanon.
