Beef has a considerably higher climate impact than meat from monogastric animals and plant-based foods, due to methane emissions from enteric fermentation in ruminants. Animal feed production also contributes considerably to the climate impact, through carbon dioxide emissions from fossil fuel use and nitrous oxide emissions from soil. Despite this...

Governance networks, made of diversified and multidisciplinary actors, have a prominent role in the development and implementation of actions for agri-food system transformation that foster both farm-level and societal change, as in the case of agroecology transitions. This article aims at delivering a typology of governance networks, building on e...

Food production and consumption need to substantially change to meet global environmental and public health goals. Increasing grain legume consumption in most countries is key to providing nourishing food for all while contributing to cropping system sustainability with relatively low environmental impact. But what actions have the potential to inc...

For the first time in its nearly 50-year history, the latest edition of the Nordic Nutrition Recommendations (NNR) provides food-based recommendations that support both healthy people and a healthy planet. Many stakeholders around the Nordics have applauded the decision to broaden the NNR analysis to include environmental sustainability. The update...

The production and consumption of animal-source foods must be transformed to mitigate negative environmental outcomes, including greenhouse gas emissions and land-use change. However, livestock are also key for food production and for livelihoods in some settings, and they can help preserve biodiversity and certain ecosystems. Previous studies have...

Background The global food system is inflicting substantial environmental harm, necessitating a shift towards more environmentally sustainable food consumption practices. Policy interventions, for example, information campaigns, taxes and subsidies and changes in the choice context are essential to stimulate sustainable change, but their effectiven...

Approximately a third of all annual greenhouse gas emissions globally are directly or indirectly associated with the food system, and over a half of these are linked to livestock production. In temperate oceanic regions, such as the UK, most meat and dairy is produced in extensive systems based on pasture. There is much interest in the extent to wh...

The purpose of this study was to estimate the climate effect from a life cycle perspective of replacing part of the forage in the winter feed of suckler cows with straw in Swedish integrated suckler calf production, calculated for a 30-cows-herd in a forest district of southern Sweden. Emissions of greenhouse gases per kg of beef and at the farm le...

Transforming the global food system is necessary to avoid exceeding planetary boundaries. A robust evidence base is crucial to assess the scale and combination of interventions required for a sustainable transformation. We developed a risk assessment framework, underpinned by a meta-regression of 60 global food system modeling studies, to quantify...

Purpose The purpose of using circularity indicators is to show the effect of changes from linear to more circular systems. This paper contributes to highlighting the importance of methodological aspects of circularity indicators in the agricultural sector when using a life cycle thinking approach. Selected circularity indicators have been explored...

Livestock have been an integral part of human societies and food systems for more than 10,000 years. Livestock products currently provide 33% of global protein intake, albeit with substantial regional variation. Large environmental impacts, high resource use and negative health outcomes associated with over-consumption of livestock products have ho...

In the EU, including Sweden, organic farming is seen as a promising pathway for sustainable production, protecting human health and animal welfare, and conserving the environment. Despite positive developments in recent decades, expanding organic farming to the Swedish national target of 30% of farmland under organic production remains challenging....

In an analysis of food system sustainability challenges and solutions among Swedish food system actors using Q-methodology, five perspectives were identified. One of the main three perspectives placed the highest priority on reduced meat consumption, food waste, and climate impact in agriculture, but downplayed strategies highlighted in the nationa...

Domesticated ruminants supply nutrient-dense foods but at a large environmental cost. However, many ruminant production systems are multi-functional, providing ecosystem services (ES) other than direct provision of food. When quantifying the climate impact of ruminant products using life cycle assessment (LCA), provisioning ES (i.e. beef and milk)...

The European Commission recently embraced the concept of agroecology as a pathway to reduce negative impacts from agri‐food systems on the environment. So far, it remains unclear whether agroecology can deliver on these high hopes if implemented on a large scale. We here assess socio‐economic and environmental implications of multiple agroecologica...

Successful transitions to agroecology require shared understanding of the sustainability implications of transitions for food systems. To gain such understanding, a transdisciplinary approach is increasingly called for by funders, end users of research and scientists. Transdisciplinary processes were used in the UNISECO project to develop strategic...

To balance trade-offs between livestock’s negative environmental impacts and their positive contributions (e.g. maintaining semi-natural grasslands, varied agricultural landscapes and crop rotations), a better understanding is needed of how the supply of ecosystem services differs across farms. We analysed a suite of indicators for non-provisioning...

There is a growing interest among farmers and consumers in increasing production and consumption of grain legumes in Sweden. This requires better knowledge among farmers and advisors about suitable species, varieties and management practices for different conditions. Since cultivar suitability and management practices are highly site-specific, farm...

Eating “less but better” meat can be a strategy to guide meat consumption in Western or high-income countries towards sustainability, but what “better” means depends on the perspective. Multiple studies and reports suggest that agroecological farming systems could contribute to a broad range of sustainability benefits, but few studies have examined...

One Health is an approach to achieve better health and well-being outcomes for people, farmed organisms and their shared environment. The One Health approach was used to analyse the impacts on the environment, people and organisms (including the pigs) of three scenarios for future pig production to ascertain their strengths and weaknesses when comp...

Replacing meat with grain legumes would benefit human health, the environment and agriculture. This study analysed legume and meat consumption practices by investigating consumer perceptions and competences relating to lightly processed grain legumes (LPL), legume-based meat substitutes (LBMS) and meat in Sweden, and how these (and demographic vari...

The contribution of seafood to global food security is being increasingly highlighted in policy. However, the extent to which such claims are supported in the current food security literature is unclear. This review assesses the extent to which seafood is represented in the recent food security literature, both individually and from a food systems...

Close to 40% of Earth's land area is used for agriculture to provide humankind with plant- and animal-based food, fibers or bioenergy. Future trends in agricultural land use, livestock husbandry and associated environmental pressures are determined by developments in the food sector, agricultural productivity, technology, and many other influencing...

The time-dependent climate impact of beef production, including changes in soil organic carbon, was examined in this study. A hypothetical suckler cow system located in south-east Sweden was analysed using a time-dependent life cycle assessment method in which yearly fluxes of greenhouse gases were considered and the climate impact in terms of temp...

In comparison with protein, dietary fat receives little attention in the food system sustainability literature, although we calculate that the average consumption of fats in many populous regions of the world is below nutritional recommendations. Animal products are the major source of dietary fat, particularly in regions with excess fat consumptio...

The alignment of the environmental, economic and social sustainability of farms is necessary for enhancing the provision of public goods in farming. This study combines the use of three tools for the assessment of farm sustainability. It provides first insights into the sustainability performance of farms at different stages of agro-ecological tran...

Pulses are important components in sustainable diets and cropping systems. This study evaluated the environmental impact of cultivation of five Swedish pulses (yellow peas, grey peas, faba beans, common beans and lentils) in a life-cycle perspective. The impact of selected Swedish pulses (conventional or organic) was then compared with that of impo...

Organic farming aims to minimize negative impacts on the local environment, but its contributions to global food sustainability also depend on a resilient food supply. We studied a farm aiming to move beyond organic and become "a sustainable farm of the future", in the farmer's own words. This meant going beyond local impacts to consider how the fa...

The European Union (EU) livestock sector relies on imported soybean as a feed source, but feeding soybean to animals leads to a loss of macronutrients compared to direct human consumption, and soybean production is associated with deforestation. Here we show that 75–82% of current EU animal fat and protein production could be sustained without soyb...

Agro-ecological approaches are fundamental for sustainable food production in the future, and the overarching objective of UNISECO is to co-develop improved and practice-validated strategies and incentives for the promotion of improved agro-ecological approaches. The key dilemma is how to produce public goods whilst maintaining viable production of...

This study analysed Swedish stakeholders’ views on future developments of organic production and consumption based on Organic 3.0, a strategic initiative by the International Federation of Organic Agriculture Movements (IFOAM). Focus group discussions were carried out with actors representing different parts of the organic value chain in Sweden. Th...

In the last years, it has been suggested to use statistical inferential methods, such as hypothesis testing or confidence intervals, to compare different products, services, or systems within comparative life cycle assessments based on Monte Carlo simulation results. However, the use of statistical inferential methods in such settings is fundamenta...

Food waste undermines long-term resilience of the global food system by aggravating ecosystem damage. The global community must therefore work to reduce the amount of food that gets wasted. However, we should be mindful of some potential conflicts between food waste reduction and food system resilience. Over-production and over-supply are a contrib...

Many consumers are willing to move to a more plant-based diet, as is apparent from the increasing demand for plant-based protein sources on many markets. There is scientific evidence that such diets are associated with lower environmental impacts, especially climate impact, land use, and energy use. However, all food production affects the environm...

Grazing systems emit greenhouse gases, which can, under specific agro-ecological conditions, be partly or entirely offset by soil carbon sequestration. However, any sequestration is time-limited, reversible, and at a global level outweighed by emissions from grazing systems. Thus, grazing systems are globally a net contributor to climate change and...

Rapidly increasing international food trade has drastically altered the global food system over the past decades. Using national scale indicators, we assess two of the resilience principles that directly reflect the effects of global trade on food systems-namely, maintaining diversity and redundancy, and managing connectivity. We perform our analys...

To reduce environmental burdens from the food system, a shift towards environmentally sustainable diets is needed. In this study, the environmental impacts of the Swedish diet were benchmarked relative to global environmental boundaries suggested by the EAT-Lancet Commission. To identify local environmental concerns not captured by the global bound...

Swedish beef and dairy farmers are currently facing a challenging financial situation. Simultaneously, beef farming contributes significant environmental impacts. To support farmers, actors from the whole value chain are now promoting Swedish beef as particularly ‘sustainable’. The paper draws on critical discourse analysis of interviews with and d...

The development of future food systems will depend on normative decisions taken at different levels by policymakers and stakeholders. Scenario modeling is an adequate tool for assessing the implications of such decisions, but for an enlightened debate, it is important to make explicit and transparent how such value-based decisions affect modeling r...

This study examined appropriate design of efficient climate taxes on consumption of food by constructing a simple theoretical model and exemplifying the results using the examples of tomatoes and beef in Sweden. The theoretical results showed that, for the tax to be efficient, i) existing taxes on greenhouse gases (GHGs) should be considered when c...

The Western diet is characterized by high meat consumption, which negatively affects the environment and human health. Transitioning toward eating more plant-based products in Western societies has been identified as a key instrument to tackle these problems. However, one potential concern is that radically reducing meat in the current diet might l...

Public sector food service is a major contributor to food waste generation in Sweden, with schools, pre-schools, elderly care homes, hospitals etc., producing approximately 70,000 tons of food waste each year. Sweden has appropriate infrastructure for handling food waste in place, recycling nutrients and energy, but there is still great potential t...

Agriculture is increasingly targeted for sustainability assessment. The social dimension has been identified as the so far least developed. Indicators of more subjective nature that might be of relevance for measuring social sustainability, are difficult to catch in traditional reductionist approaches. Therefore new approaches have had to be devel...

The need for more sustainable production and consumption of animal‐source food is central to the achievement of the sustainable development goals: within this context, wise use of land is a core challenge and concern. A key question in feeding the future world is: how much animal‐source food should we eat? We demonstrate that livestock raised under...

Current organic agriculture performs well in several sustainability domains, like animal welfare, farm profitability and low pesticide use, but yields are commonly lower than in conventional farming. There is now a re-vitalized interest in increasing yields in organic agriculture to provide more organic food for a growing, more affluent population...

Farming is the foundation of our food system. While the prerequisite for farming is a clean environment and a diverse nature, agriculture is currently the cause of major environmental problems, including greenhouse gas and nitrogen emissions. The challenge to protect our environment and feed the world sometimes seem insurmountable, but solutions mi...

The report dissects claims made by different stakeholders in the debate about so called ‘grass-fed’ beef, the greenhouse gases the animals emit, and the possibility that, through their grazing actions, they can help remove carbon dioxide from the atmosphere. It evaluates these claims and counterclaims against the best available science, providing a...
