Trend and future scenario analyses of Singapore's food system through the lens of life cycle environmental impact

Abstract

Abstract Singapore imports more than 90% of the food consumed with the remaining being produced in farms locally. With Singapore's commitment to achieving the United Nations’ sustainable development goals and the recently announced “30 by 30” goal of raising the current food production levels from the current 10–30% of the nation's food needs by 2030, there is an emphasis to raise productivity, strengthen climate resilience and also tackle resource constraints. This work presents the current trend analysis of Singapore's food supply and consumption through the lens of life cycle environmental impacts. With this as a baseline, multiple future scenarios are presented based on different anticipated shifts as a comparison. Based on the “30 by 30” goal, these future scenario analyses describe shifts towards optimal health diet and plant-based diet through alternative plant-based meats, and will be further discussed to derive insights on how they may affect future outcomes in terms of environmental impacts and what they mean for decision-making or policy-making.
