The current global food system is inadequate to meet the needs of the current world population without compromising future well-being. For example, current intensified production systems lead to undernutrition in some regions coupled with epidemics of obesity in others while compromising their underlying ecological foundations, such as creating areas of ocean hypoxia. Such common observations challenge the research community to ask new types of basic questions and apply novel analytical frameworks for analyzing them. Elaboration of an integrated applied research agenda is imperative to addressing these global food system challenges. We propose that core competencies of a new analytical framework lie at the intersection of four domains: (1) the ecology of agroecosystems; (2) equity in global and local food systems; (3) cultural dimensions of food and agriculture; and (4) human health. This intersection constitutes a new analytical framework for transitions toward global food system sustainability.
The allegory of freeing Prometheus, most literally the freeing of humans from the will of celestial deities, is widely used as metaphor for seemingly impossible actions for liberation1. The seemingly impossible action of liberating the world from an unsustainable global food system has emerged as a major international environmental and geo-political concern (Heller and Keoleian, 2003; McMichael, 2011; Hunter et al., 2017). Faced with striking contradictions (e.g., dramatic increases in production of some food crops, coupled with coastal marine hypoxia (Nassauer et al., 2007; Diaz and Rosenberg, 2008) and natural resource degradation (Foley et al., 2005); widespread undernutrition in certain regions coupled with an emerging global epidemic of obesity (Caballero, 2007; Franklin et al., 2012), both popular and academic analysts have repeatedly warned of an unfolding crisis. Anxiety over global food security and food system sustainability are clearly cause for concern, but, like unchaining Prometheus, addressing such a multi-faceted problem can seem insurmountable. A host of highly focused topics on the global food system is already receiving careful scrutiny, ranging from characterizing the soil microbiome in agricultural systems, to detailed study of the eating habits of preschool and school- aged children, to global food politics and market futures in the context of subsidies and taxation. Such diverse topics are among the many elements in a broad set of interdisciplinary themes that constitute a new and essential challenge for applied academic research—developing a new paradigm for the sustainability of local, regional and the global food system that “puts it all together2.” Can we “feed” Prometheus, which is to say can we provide the desperately needed intellectual background for the transformation the world needs?
Previous research paradigms isolated component parts of the food system, such as crop production, rural livelihoods, and nutrition patterns, within preexisting disciplines such as agronomy, sociology, or nutritional science. Lack of attention to complex relationships among these and other components of a multi-level, integrated food system contributed to the emergence of the so-called productionist paradigm, which emphasizes yield over broader food system and sustainability goals (Tomlinson, 2013). Such an underlying framework is not wrong on its surface, but is limiting and fails to acknowledge some well-known food-related contradictions and unintended side effects. For example, the world already produces enough edible calories to feed 9 billion people in principle3 yet food insecurity is widespread (e.g., 815 million people were chronically undernourished in 2016; FAO et al., 2017). Most current food and agriculture systems worldwide generate diverse environmental concerns (Tilman et al., 2001), yet global diets have become remarkably homogenized (Khoury et al., 2014). Economic inequities continue to deepen for both producers and consumers of food (Borgerhoff Mulder et al., 2009), particularly for small-scale farmers who are still the majority of farmers globally (98% of all farms, on 53% of agricultural land; Graeub et al., 2015) and who face increasing threats to their livelihoods (Wiggins et al., 2010). Indeed, the nutritional quality or safety of food continues to deteriorate, contributing in large part to the widespread burden of micronutrient deficiencies and obesity globally (Nestle, 2003). Such problems speak to the mandate for a new environmental, social, and economic paradigm, one that views all elements of food systems as part of a single, comprehensive framework. The growth of food systems studies throughout the academy is testament to the emergence of a new scholarly focus that is genuinely interdisciplinary4. The subject matter of this new paradigm can be summarized as the intersection of four foci: (1) the ecology of agroecosystems, including all environmental consequences;5 (2) equity issues in global and local food systems; (3) cultural dimensions of food and agriculture; and (4) human health, both personal and public.
Agricultural ecology is now a major component of the natural science of ecology more generally, with the agroecosystem viewed as operating within the realm of general ecological principles. Yet the elementary framings of ecology are frequently given short shrift in the design, both formal and informal, of agricultural production systems. Underpinning a new food systems paradigm is the recognition that agroecosystems operate much like other ecosystems. As a result, designing agroecosystems based on ecological science would reduce both external inputs to, and ecological and environmental costs of, crop production. Within this framing, the biodiversity that is planned (agrobiodiversity) and associated (wild biodiversity) is essential for the delivery of ecosystem services (Wood et al., 2015). A broader focus on managing ecological interactions on farms would reduce the negative environmental consequences of agriculture. Especially in the climate-changing Anthropocene, agriculture looms large as either a major contributor to greenhouse gas emissions (10–12% of all emissions)6 or, if performed properly, an important entry point for mitigation and adaptation (Zomer et al., 2016).
Equity issues are essential to solving the food crisis. Availability of food is not the same as access to it. Access to healthy, diverse, affordable food is the crux of food insecurity worldwide, in both urban and rural areas (Ruel et al., 2017). Resolving the dilemma of scarcity within abundance, a major sociopolitical issue of our day, is recognized by many scholars as a difficult but crucial contemporary challenge, highlighting one of the modern system's starkest contradictions—an abundance of food, yet so many millions remaining food insecure (FAO et al., 2017). Closely tied to uneven food access is the widening economic divide among farmers, rooted in the continuing loss of small and mid-sized farms, which are unable to compete in a system that encourages concentration in the agrifood system (Byerlee and Deininger, 2013; Lowder et al., 2016). Further, environmental alterations, such as those resulting from climate change, are expected to affect farmers differentially, with much of the burden falling on smallholder farmers (Morton, 2007) who produce over 50% of global food production. For these farmers, losses in agricultural production are not only a matter of food security, but also of welfare given that agriculture is a primary form of livelihood for the nearly billion smallholder farmers across the globe.
Food is at the heart of human cultures and therefore culture is an integral component of food system studies. The resources and services provided by local ecosystems, and the knowledges, skills, and meanings that go into managing and sustaining them, contribute significantly to cultural identity and diversity (Richards, 1985; Vasavi, 1999). Cultural dimensions are thus at the heart of what and how food is produced, exchanged and consumed; they mediate the gap between calculations of food calories and peoples' notions of good food and fulfilling agriculture (Mintz and Du Bois, 2002; Counihan and Van Esterik, 2013). After millennia of crop diversification, the globalizing forces of the Anthropocene have generated a tendency toward dietary homogenization, based on a Western diet (Khoury et al., 2014). The concomitant reduction in diversity of food and consequently of some cultures themselves, points to a crisis of democracy evident in contemporary food systems. The need for engaging diverse voices in negotiating the (re)design of local and global food systems is imperative if greater equity and cultural self-determination are to be realized.
Food is also at the heart of human health worldwide. Across the globe, ischemic heart disease, stroke, diabetes and other diet-related non-communicable diseases are top contributors to lost years of healthy life, and are responsible for an enormous economic burden (Murray et al., 2012). In low- and middle-income countries, infectious illnesses and micronutrient deficiencies, linked to unhygienic food preparation and inadequate nutrition, are additional major concerns. Healthy diets remain a goal for all people in all societies, yet obesity and other diet-related diseases are expanding worldwide, although not uniformly. Linking global public health to the type, quality and availability of food is an essential part of the new paradigm.
A global food system that leaves millions food insecure while contributing to obesity, that generates significant collateral environmental degradation, and that compromises the wellbeing of consumers and producers alike challenges the academic community to ask new types of basic research questions and apply novel analytical frameworks for analyzing them. Elaboration of an integrated applied research agenda is imperative to addressing these global food system challenges. We propose that an intersection of the four domains above comprise core competencies of a new analytical framework for transitions toward global food system sustainability. Such structure would inform new, transdisciplinary, and high-impact research questions that will help re-route the food system toward a path of environmental, social, and economic sustainability (Wittman et al., 2017). Unchaining the condemned Prometheus is a liberating goal. We call on the academic community to not only free him, but sustain him with this urgently needed metaphorical food.

Conflict of Interest Statement
The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.
1. ^Unchaining Prometheus is a well-worn metaphor for liberating actions, most broadly the freeing of humans from the will of the gods. Because of the crime of stealing fire from Zeus, Prometheus was chained to a rock to be attacked daily by an eagle who ate his liver, which regenerated each day only to invite the eagle once again to the liver, condemning Prometheus to an eternity of suffering. Unchaining him becomes the liberating goal. Our title is inspired by a quote in a different context from playwright Bertold Brecht. “Our audience must experience not only the ways to free Prometheus, but be schooled in the very desire to free him. Theater must teach all the pleasures and joys of discovery, all the feelings of triumph associated with liberation.” Essays on the Art of Theater (1954).
2. ^Within this sustainability paradigm we of course include issues of resistance and resilience along with other popular framings such as agroecosystem health, food security and food sovereignty (Hoy, 2015; Schipanski et al., 2016).
3. ^In the recently published “Beginning to end hunger: Food and the environment in Brazil and beyond” (2017, U. California Press), Chappell makes the simple calculations that, with the recommended 2,300 calories per person per day, and the many estimates of current production at approximately the equivalent of 2,903 calories per day for the current population of 7.25 billion people, elementary calculations show that current production would supply 9.14 billion people with their daily recommended calories, with no other changes in the food system.
4. ^Our Sustainable Food System Initiative at the University of Michigan is one such example that includes a broad range of topics. Under the same banner we can cite, for example, the principles of agroecology (Vandermeer and Perfecto), the genetics of herbicide resistance (Baucom), large-scale indirect “planning” of small farms (Hoey, Jain), or the problem of conceptualizing sustainable diets (Jones et al., 2016), among others (see our web page at https://sites.lsa.umich.edu/sustainablefoodsystems/).
5. ^We aknowledge that transforming the agroecosystem is a major problem that requires a political-economic analysis of the structural connections that perpetuate the current—non-sustainable and inequitable—model and prevents the scaling of agroecological alternatives. A large literature already exists on this issue (Hinrichs, 2014; Sage, 2014; Duru and Therond, 2015; IPES, 2015; DeLonge et al., 2016; Howard, 2016; De Schutter, 2017; Miles et al., 2017; Sanderson Bellamy and Ioris, 2017; Pimbert and Moeller, 2018).
