Comparing urban food system characteristics and actions in US and Indian cities from a multi‐environmental impact perspective: Toward a streamlined approach

Abstract

Food action plans in many global cities articulate interest in multiple objectives including reducing in-and trans-boundary environmental impacts (water, land, greenhouse gas (GHG)). However, there exist few standardized analytical tools to compare food system characteristics and actions across cities and countries to assess trade-offs between multiple objectives (i.e., health, equity) with environmental outcomes. This paper demonstrates a streamlined model applied for analysis of four cities with varying characteristics across the United States and India, to quantify system-wide water, energy/GHG, and land impacts associated with multiple food system actions to address health, equity, and environment. Baseline diet analysis finds key differences between countries in terms of meat consumption (Delhi 4; Pondicherry 16; United States 59, kg/capita/year), and environmental impact of processing of the average diet (21%, 19%, <1%, <1% of community-wide GHG-emissions for New York, Minneapolis, Delhi, and Pondicherry). Analysis of supply chains finds city average distance (food-miles) varies (Delhi 420; Pondicherry 200; United States average 1,640 km/t-food) and the sensitivity of GHG emissions of food demand to spatial variability of energy intensity of irrigation is greater in Indian than US cities. Analysis also finds greater pre-consumer waste in India versus larger post-consumer accumulations in the United States. Despite these differences in food system characteristics, food waste management and diet change consistently emerge as key strategies. Among diet scenarios, all vegetarian diets are not found equal in terms of environmental benefit, with the US Government's recommended vegetarian diet resulting in less benefit than other more focused targeted diet changes.

Many cities are developing food action plans, with multiple objectives related to health and nutrition, environmental sustainability, equity, and economy. Multiple international organizations, such as the Milan Urban Food Pact, and Food and Agriculture Organization's (FAO's) Food for the Cities are currently working to help cities create changes in their food system related to these multiple sustainability outcomes. Many of these urban food actions align with United Nations Sustainable Development Goals (SDGs) related to the food system, including "Zero hunger" (Goal 2), "Good health and well-being" (Goal 3), "Decent work and economic growth" (Goal 8), "Reduce inequalities" (Goal 10), and multiple environmental goals (Goals 11-15), for example. However, for a city to take action in their food system to achieve these multiple sustainability outcomes, this requires first an understanding of the structure and character...

Quantitative Assessment of Trout Fish Spoilage with a Single Nanowire Gas Sensor in a Thermal Gradient

“…Fresh food is even more susceptible to this problem as it deteriorates rapidly and this affects not only the food industry but also the health of consumers, with social and health costs [ 1 , 2 ]. Production chains and distribution networks have expanded and become more complicated and this has increased the time by which food reaches the consumer [ 3 ].…”

Detection of Mackerel Fish Spoilage with a Gas Sensor Based on One Single SnO2 Nanowire

“…Unfortunately, fresh food is subject to deterioration quite rapidly, and this has important repercussions not only on the food industry, but also on the health of consumers, with social and health costs [1,2]. Recently, the globalization and the centralization of many production chains has led to greater distances between the production areas and the consumer and more complex supply chains [3]. Fish is a food that, also thanks to its healthy properties, is consumed more and more all over the world [4].…”

Sustainable Agri-Food Systems: Environment, Economy, Society, and Policy

“…Many scholars have called for adopting more sustainable, plant-based diets [60, [203][204][205][206] to reduce the environmental impacts of the current food systems. These include examples such as the Mediterranean diet [206,207], vegetarian diets [60, [208][209][210], and the vegan diet [211]. However, Forber et al [86] warned that the adoption of plant-based diets (e.g., vegan, flexitarian) might add to the wastewater phosphorus burden in the UK.…”
