Public and private food consumption is responsible for significant environmental impacts, resulting in numerous studies that highlight the problem and reveal its magnitude at global and national scales. Drawing on a high level of data aggregation and focussing on individual choices and attitudes, current accounts stop short of grappling with the underlying complexity of the phenomenon. In this paper, we explore the conceptual value and methodological feasibility of linking Material Flow Analysis (MFA) and Social Practice Theory (SPT) to apprehend household food consumption dynamics. We develop and pilot a “Practice-extended MFA” framework among selected households in Bangalore, India. While MFA modelling serves to describe and quantify all food consumption processes and related flows at the micro-level, SPT is applied to investigate how individual, technological and sociological aspects of consumption practices converge towards household food “metabolic profiles”. The results revealed a complex system of interactions between food provisioning, storage and management practices, as well as socio-cultural norms. The paper concludes by emphasizing the contribution of a reflective stance between household metabolisms and consumption practices revealing not only what and how much food is consumed and wasted, but why and in what way.

Abstract: Globalization and economic liberalization are enabling individuals in emerging economies like India to access lifestyles similar to the resource-intense West. This spread of consumerism poses substantial ecological challenges, and calls for studies that investigate the environmental values, ethics, and politics of India's new consumers. In this paper, I explore emerging pro-environmental behaviors in the city of Bangalore, India, among the new middle classes- its most significant consumer class. Using the case of home waste management, I show how household behavior change is made possible by neighborhood-based coordination, involving multiple actors such as environmentally-conscious residents, domestic help, and hired waste workers. Drawing on ecological citizenship theory, I discuss how waste management through recycling and composting is being implemented in Bangalore through networks of socio-economically privileged new middle class individuals. Their privileged social, political, and economic positions enable them to collectively enact changes in their cultural and structural contexts to facilitate pro-environmental initiatives. At the same time, the role of other actors like domestic servants and waste workers is also critical to the process. I show how ecological citizenship theory can be used to analyze and highlight voluntary involvement by socio-economically privileged individuals but fails to recognize the contributions of actors, who through their livelihood practices, play a pivotal role in producing the systems that enable pro-environmental behaviors among the elite. I conclude by suggesting that a critical analysis of the processes and political arrangements that produce pro-environmental behaviors is vital to sustainable consumption and production research in emerging economies like India.
