Identifying Cool Food Meals

Cool Food is a global initiative that aims to help food providers sell dishes with smaller climate footprints. This technical note outlines the methods used by World Resources Institute (WRI) to identify a set of Cool Food Meals on a food provider’s menu. Drawing on the calculation methods established under the Cool Food Pledge, Cool Food Meals must fall under a maximum threshold of per-meal greenhouse gas (GHG) emissions based on recipe data submitted to WRI. In addition, Cool Food Meals are subject to a nutrition safeguard to ensure they meet a minimum threshold of nutritional quality. Designation of Cool Food Meals is open to food providers that are Cool Food Pledge members, Cool Food “Heroes” who serve an especially low-GHG-emitting menu, or food providers for whom at least 20 percent of annual sales are dishes that qualify as Cool Food Meals. Publicly recognizing climate-friendly food providers, and steering consumers toward low-emitting menu options, can help accelerate the transition toward a sustainable food future.

Use of Lactic Acid Bacteria to Reduce Methane Production in Ruminants, a Critical Review.

Enteric fermentation in ruminants is the single largest anthropogenic source of agricultural methane and has a significant role in global warming. Consequently, innovative solutions to reduce methane emissions from livestock farming are required to ensure future sustainable food production. One possible approach is the use of lactic acid bacteria (LAB), Gram positive bacteria that produce lactic acid as a major end product of carbohydrate fermentation. LAB are natural inhabitants of the intestinal tract of mammals and are among the most important groups of microorganisms used in food fermentations. LAB can be readily isolated from ruminant animals and are currently used on-farm as direct-fed microbials (DFMs) and as silage inoculants. While it has been proposed that LAB can be used to reduce methane production in ruminant livestock, so far research has been limited, and convincing animal data to support the concept are lacking. This review has critically evaluated the current literature and provided a comprehensive analysis and summary of the potential use and mechanisms of LAB as a methane mitigation strategy. It is clear that although there are some promising results, more research is needed to identify whether the use of LAB can be an effective methane mitigation option for ruminant livestock.

Understanding the Relations Among the Storage, Soaking, and Cooking Behavior of Pulses: A Scientific Basis for Innovations in Sustainable Foods for the Future.

The world faces challenges that require sustainable solutions: food and nutrition insecurity; replacement of animal-based protein sources; and increasing demand for convenient, nutritious, and health-beneficial foods; as well as functional ingredients. The irrefutable potential of pulses as future sustainable food systems is undermined by the hardening phenomenon that develops upon their storage under adverse conditions of temperature and relative humidity. Occurrence of this phenomenon indicates storage instability. In this review, the application of a material science approach, in particular the glass transition temperature concept, is presented to explain phenomena of storage instability such as the occurrence of hardening and loss of viability under adverse storage conditions. In addition to storage (in)stability, application of this concept during processing of pulses is discussed. The state-of-the-art on how hardening occurs, that is, mechanistic insights, is provided, including a critical evaluation of some of the existing postulations using recent research findings. Moreover, the influence of hardening on the properties and processing of pulses is included. Prevention of hardening and curative actions for pulses affected by the hardening phenomenon are described in addition to the current trends on uses of pulses and pulse-derived products. Based on the knowledge progress presented in this review, suggestions for the future include: first, the need for innovation toward implementation of recommended solutions for the prevention of hardening; second, the optimization of the identified most effective and efficient curative action against hardening; and third, areas to focus on for elucidation of mechanisms of hardening, although existing analytical methods require advancement.

Multiplicity of Perspectives on Sustainable Food: Moving Beyond Discursive Path Dependency in Food Policy

The idea that a sustainable transformation of the food system is urgently needed is gaining ground throughout Europe. Yet, opinions differ substantially on what a sustainable food future exactly entails, and on how this future may be achieved. This article argues that recognising this multiplicity of opinions and perspectives in policy making is productive because it creates attentiveness to innovative ideas and initiatives, and may contribute to a broad social support base for policy choices. However, food policy makers may overlook the diversity in perspectives by unreflexively adopting understandings of problems and solutions that are historically dominant in their organisations. In this article, we reveal the usefulness of triggering reflection on such discursive path dependencies amongst policy makers. We do so by presenting a three-fold case study that we conducted in the Netherlands. First, we analytically distinguish five perspectives on sustainable food that feature prominently in the Dutch public debate. Subsequently, we show that only two out of these five perspectives predominantly informed a Dutch food policy—despite intentions to devise a more integrated policy approach. Finally, we discuss the findings of two focus groups in which we discussed our analyses with Dutch civil servants who have been involved in drafting the Dutch food policy. These focus groups triggered reflection among the civil servants on their own perspectival biases as well as on discursive path dependencies in Dutch food policy making. We conclude by discussing the implications of our findings for the understanding of the discursive politics of sustainable agro-food transformations in Europe.

New pathways for governing food system transformations: a pluralistic practice-based futures approach using visioning, back-casting, and serious gaming

The global environmental change that characterizes the Anthropocene poses a threat to food systems. Cities increasingly serve as the spaces where civil society, private actors, and local governments come together to strategize toward more sustainable food futures and experiment with new forms of food governance. However, much of the futures literature in the context of sustainability focuses on large-scale, global scenarios. These are important pieces of knowledge, but they often do not effect a change in local perspectives and practices. In this paper we respond to the need for novel futures approaches to help urban coalitions of societal actors create pathways to sustainability transformations. We investigate how existing examples of good practices, or “seeds,” can be used to open up novel, desirable, bottom-up futures in the case study of Kyoto (Japan). Innovative combinations of methodologies (visioning, back-casting, simulation games) are used and assessed in order to create multiple ways of experimenting and engaging with food system futures. Our results consist of a pluriform pathway to a sustainable Kyoto food system. Each method brings in its unique pathway elements: visioning to formulate a desired end goal, back-casting to create a step-by-step action plan, and gaming to practice with the future. The combination of Kyoto-based “seeds” with initiatives from elsewhere and with a new food system governance model (a food policy council) resulted in participants learning about new food system practices, extending their networks, and support for actualizing a food policy council. We conclude that multimethod futures processes that combine existing practices and new modes of governance are a promising new way to outline various pathways for sustainability transformations.

New approaches in securing more sustainable urban food futures: case from Cologne-Bonn region

Urban food systems undergo a huge transformation. Many cities worldwide are involved; they start to reconsider their current food supply system. This study will describe some developments in the Cologne-Bonn area, Germany, which have the potential to introduce new pathways for more sustainable food futures. Recent developments in urban food systems in the Cologne-Bonn region are very much “bottom-up”, driven by lively and committed actors (gardeners, farmers, civil society). In this paper potential synergies and conflicts in the emerging urban agriculture activities, focusing on producer-consumer relations and evolving co-productive approaches are discussed. We further try to understand motivations, aims and visions of the diverse participants of such models. By using qualitative methods of empirical social research such as narratives and semi-structured interviews primary data were collected in the case region. Until now there is no consensus in the literature about the optimal institutional set-ups for the permanent adoption of the various forms of urban agriculture. Preliminary governance analysis showed that especially institutionalized forms seem to be robust and sustainable. The further exploration of the cases will also contribute to understand the dynamics coming from the involvement of citizens in the agricultural production. Co-productive or participatory agriculture, which includes the consumer into the production process, has the potential to change the way of urban food supply. It is hypothesized that shared motivations and visions between producers and consumers in favor of a sustainable food system will help to stabilize alternative food systems whereas conflicts need to be anticipated to deepen the understanding of problems in the producer-consumer co-productive process. Our first results demonstrate that co-productive models of today are primarily based on idealism from both sides and also bear the potential of conflicts. It will be up to further research and innovation to address these issues and also check the new approaches on economic viability.

Modulating plant growth-metabolism coordination for sustainable agriculture.

Enhancing future global food security by increasing cereal Green Revolution Variety (GRV) productivity risks escalating collateral environmental damage from inorganic nitrogen (N) fertilizers. Whilst crop N use-efficiency (NUE) improvements are therefore essential, they require in-depth understanding of unknown co-regulatory mechanisms integrating growth, N assimilation and carbon (C) fixation. Here we show that the balanced opposing activities and physical interactions of the rice GROWTH-REGULATING FACTOR 4 (OsGRF4) transcription factor and the DELLA growth-inhibitor confer homeostatic co-regulation of growth, C and N metabolism. OsGRF4 promotes and integrates N assimilation, C fixation and growth, whilst DELLA inhibits them. In consequence, the DELLA accumulation characteristic of GRVs confers yield-enhancing dwarfism, but also reduces NUE. However, GRV NUE and grain yield are increased by tipping the OsGRF4-DELLA balance towards increased OsGRF4 abundance. Modulation of plant growth and metabolic co-regulation thus enables novel breeding strategies for future sustainable food security and a new Green Revolution.

Strategies for feeding the world more sustainably with organic agriculture

Organic agriculture is proposed as a promising approach to achieving sustainable food systems, but its feasibility is also contested. We use a food systems model that addresses agronomic characteristics of organic agriculture to analyze the role that organic agriculture could play in sustainable food systems. Here we show that a 100% conversion to organic agriculture needs more land than conventional agriculture but reduces N-surplus and pesticide use. However, in combination with reductions of food wastage and food-competing feed from arable land, with correspondingly reduced production and consumption of animal products, land use under organic agriculture remains below the reference scenario. Other indicators such as greenhouse gas emissions also improve, but adequate nitrogen supply is challenging. Besides focusing on production, sustainable food systems need to address waste, crop–grass–livestock interdependencies and human consumption. None of the corresponding strategies needs full implementation and their combined partial implementation delivers a more sustainable food future.

Greedy or needy? Land use and climate impacts of food in 2050 under different livestock futures

Abstract Both supply and demand side changes are necessary to achieve a sustainable food system. However, the weight accorded to these depends on one’s view of what the priority goals are for the food system and the extent to which production systems versus consumption patterns are open to change. Some stakeholders see the problem as one of ‘not enough food’ and focus on the need to sustainably increase supply, while others consider the resource demanding and ‘greedy’ consumption patterns of the Western world as the main problem and emphasize the need to shift diets. In this study global land use and greenhouse gas emissions are estimated for a set of scenarios, building on four ‘livestock futures’ reflecting these different perspectives. These scenarios are: further intensification of livestock systems; a transition to plant-based eating; a move towards artificial meat and dairy; and a future in which livestock production is restricted to the use of ‘ecological leftovers’ i.e. grass from pastures, food waste and food and agricultural byproducts. Two dietary variants for each scenario are modelled: 1) a projected diet following current trends and 2) a healthy diet with more fruits and vegetables and fewer animal products, vegetable oils and sugar. Livestock production in all scenarios (except the baseline scenario) was assumed to intensify to current levels of intensive production in North-Western Europe. For each scenario, several variant assumptions about yield increases and waste reductions were modelled. Results show that without improvements in crop productivity or reductions on today’s waste levels available cropland will only suffice if production of all protein currently supplied by animal foods is replaced by (hypothetical) artificial variants not requiring any land. With livestock intensities corresponding to current ones in North-Western Europe and with yield gaps closed by 50% and waste reduced by 50%, available cropland will suffice for all scenarios that include a reduction of animal products and/or a transition to poultry or aquaculture. However, in the scenario based on an extrapolation of current consumption patterns (animal product amounts and types consumed in proportions corresponding to the current average consumption in different world regions) and with livestock production based on feed from cropland, available cropland will not be enough. The scenario that makes use of pastures for ruminant production and food waste for pigs, uses considerably less cropland and could provide 40–56 kg per capita per year of red meat. However, such a livestock future would not reduce GHG emissions from agriculture on current levels. This study confirms previous research that to achieve a sustainable food future, action is needed on all fronts; improved supply and reduced demand and waste.

Evaluation of soil health in organicvs. conventional farming of basmati rice in North India

AbstractConventional agricultural practices that use excessive chemical fertilizers and pesticides come at a great price with respect to soil health, a key component to achieve agricultural sustainability. Organic farming could serve as an alternative agricultural system and solve the problems associated with the usage of agro‐chemicals by sustainable use of soil resources. A study was carried out to evaluate the impact of organicvs. conventional cultivations of basmati rice on soil health during Kharif (rainy) season of 2011 at Kaithal district of Haryana, India, under farmers' participatory mode. Long‐term application of organic residues in certified organic farms was found to improve physical, chemical, and biological indicators of soil health. Greater organic matter buildup as indicated by higher soil organic carbon content in organic fields was critical to increase soil aggregate stability by increasing water holding capacity and reducing bulk density. Proper supplementation of nutrients (both major and micro nutrients) through organic residue addition favored biologically available nutrients in organic systems. Further, the prevalence of organic substrates stimulated soil microorganisms to produce enzymes responsible for the conversion of unavailable nutrients to plant available forms. Most importantly, a closer look at the relationship between physicochemical and biological indicators of soil health evidenced the significance of organic matter to enzyme activities suggesting enhanced nutrient cycling in systems receiving organic amendments. Enzyme activities were very sensitive to short‐term (one growing season) effects of organicvs. conventional nutrient management. Soil chemical indicators (organic matter and nutrient contents) were also changed in the short‐term, but the response was secondary to the biochemical indicators. Taken together, this study indicates that organic farming practices foster biotic and abiotic interactions in the soil which may facilitate in moving towards a sustainable food future.

Agrobiodiversity and a sustainable food future.

The biodiversity of food plants is vital for humanity's capacity to meet sustainability challenges. This goal requires the rigorous integration of plant, environmental, social and health sciences. It is coalescing around four thematic cornerstones that are both interdisciplinary and policy relevant.

What role for trade in food sovereignty? Insights from a small island archipelago

The food sovereignty movement has been gathering momentum in advocating the rights of individuals and nations to control their own food systems. Alongside this is a mounting critical engagement regarding its privileging of local food production as the means through which to achieve this goal. Adopting a place-based approach, we explore the foodways of diverse communities across a small island archipelago – the Turks and Caicos Islands in the West Indies. Based on interviews and focus groups, we unpack narratives relating to islanders’ changing food practices and aspirations. These are understood as two competing but inter-related themes of disruption and reification of current practices shaped by wider food regimes in interaction with ecological challenges. Given that conditions of historic dependency implicate the islands in a myriad of dependent trade relationships, we argue that small island economies offer, and require, unique cases for understanding how sovereign conditions for trade might be developed in line with a food sovereignty framework. We underline the importance of an inter-disciplinary focus for bringing forth a nuanced understanding of what might be required to shape more sustainable, sovereign and secure food futures. Doing so is necessarily rooted in an appreciation of islanders’ accounts of social, economic, political and ecological change over time.

Governments, grassroots, and the struggle for local food systems: containing, coopting, contesting and collaborating

Local sustainable food systems have captured the popular imagination as a progressive, if not radical, pillar of a sustainable food future. Yet these grassroots innovations are embedded in a dominant food regime that reflects productivist, industrial, and neoliberal policies and institutions. Understanding the relationship between these emerging grassroots efforts and the dominant food regime is of central importance in any transition to a more sustainable food system. In this study, we examine the encounters of direct farm marketers with food safety regulations and other government policies and the role of this interface in shaping the potential of local food in a wider transition to sustainable agri-food systems. This mixed methods research involved interview and survey data with farmers and ranchers in both the USA and Canada and an in-depth case study in the province of Manitoba. We identified four distinct types of interactions between government and farmers: containing, coopting, contesting, and collaborating. The inconsistent enforcement of food safety regulations is found to contain progressive efforts to change food systems. While government support programs for local food were helpful in some regards, they were often considered to be inadequate or inappropriate and thus served to coopt discourse and practice by primarily supporting initiatives that conform to more mainstream approaches. Farmers and other grassroots actors contested these food safety regulations and inadequate government support programs through both individual and collective action. Finally, farmers found ways to collaborate with governments to work towards mutually defined solutions. While containing and coopting reflect technologies of governmentality that reinforce the status quo, both collaborating and contesting reflect opportunities to affect or even transform the dominant regime by engaging in alternative economic activities as part of the ‘politics of possibility’. Developing a better understanding of the nature of these interactions will help grassroots movements to create effective strategies for achieving more sustainable and just food systems.

Synergies in alternative food network research: embodiment, diverse economies, and more-than-human food geographies

As ecologically and socially oriented food initiatives proliferate, the significance of these initiatives with respect to conventional food systems remains unclear. This paper addresses the transformative potential of alternative food networks (AFNs) by drawing on insights from recent research on food and embodiment, diverse food economies, and more-than-human food geographies. I identify several synergies between these literatures, including an emphasis on the pedagogic capacities of AFNs; the role of the researcher; and the analytical and political value of using assemblage and actor-network thinking to understand the far-reaching forces and power disparities confronting proponents of more ethical and sustainable food futures.

Microbial protein: future sustainable food supply route with low environmental footprint.

SummaryMicrobial biotechnology has a long history of producing feeds and foods. The key feature of today's market economy is that protein production by conventional agriculture based food supply chains is becoming a major issue in terms of global environmental pollution such as diffuse nutrient and greenhouse gas emissions, land use and water footprint. Time has come to re‐assess the current potentials of producing protein‐rich feed or food additives in the form of algae, yeasts, fungi and plain bacterial cellular biomass, producible with a lower environmental footprint compared with other plant or animal‐based alternatives. A major driver is the need to no longer disintegrate but rather upgrade a variety of low‐value organic and inorganic side streams in our current non‐cyclic economy. In this context, microbial bioconversions of such valuable matters to nutritive microbial cells and cell components are a powerful asset. The worldwide market of animal protein is of the order of several hundred million tons per year, that of plant protein several billion tons of protein per year; hence, the expansion of the production of microbial protein does not pose disruptive challenges towards the process of the latter. Besides protein as nutritive compounds, also other cellular components such as lipids (single cell oil), polyhydroxybuthyrate, exopolymeric saccharides, carotenoids, ectorines, (pro)vitamins and essential amino acids can be of value for the growing domain of novel nutrition. In order for microbial protein as feed or food to become a major and sustainable alternative, addressing the challenges of creating awareness and achieving public and broader regulatory acceptance are real and need to be addressed with care and expedience.

Normalised, human-centric discourses of meat and animals in climate change, sustainability and food security literature

The large-scale, intensive production of meat and other animal products, also known as the animal-industrial complex, is our largest food system in terms of global land use and contribution to environmental degradation. Despite the environmental impact of the meat industry, in much of the policy literature on climate and environmental change, sustainability and food security, meat continues to be included as part of a sustainable food future. In this paper, I present outcomes of a discourse analysis undertaken on a selection of key major international and Australian reports. After highlighting common themes in the ways that meat and animals are discussed, I draw on the animal studies literature to critically analyse the assumptions underpinning such policy documents. My analysis illustrates that animals are effectively de-animated and rendered invisible in these bodies of literature by being either aggregated—as livestock, units of production and resources, or materialised—as meat and protein. These discursive frames reflect implicit understandings of meat as necessary to human survival and animals as a natural human resource. A critical examination of these understandings illustrates their dual capacity to normalise and encourage the continuation of activities known to be seriously harming the environment, climate and human health, while at the same time obstructing and even denigrating alternative, less harmful approaches to food. In response, I offer some conceptual and analytical modifications that can be easily adopted by researchers on climate change, sustainability and food security with the aim of challenging dominant discourses on meat and animals.
