Environmental Sustainability of Food Environments: Development and Application of a Framework in 4 cities in South Asia.

Background: Food environments, where people directly engage with broader food systems, may be an important contributor to the environmental sustainability of food systems. Objectives: The primary objectives of this study were to establish a new food environment framework that considers environmental indicators and to assess data availability and gaps using data previously collected as part of a food systems survey in 4 South Asian cities. Methods: The framework was developed by conducting a structured literature review of previous food environment frameworks and in-depth interviews with content experts ( Results: We have expanded the sustainability domain within food environments to include consumer travel to food vendors, the presence of food delivery services, policies related to sustainability, vendor food waste, vendor plastic use, vendor utility usage, vendor recycling and waste management practices, and food packaging. Mapping the framework to existing data from 4 cities in South Asia, we found variations in food environment sustainability indicators, particularly regarding consumer transportation to food vendors, the presence of delivery services, and food waste. Conclusions: Although the majority of food environment research focuses on the availability and affordability of healthy foods, there is an urgent need to understand better how aspects of food environments contribute to environmental goals. When mapping the framework to existing food systems data, we found gaps in data on environmental sustainability in food environments and variation in indicators across settings.
