Conservation interventions are being implemented at various spatial scales to reduce the impacts of rising global population and affluence on biodiversity and ecosystems. While the direct impacts of these conservation efforts are considered, the unintended consequences brought about by market feedback effects are often overlooked. Perverse market outcomes could result in reduced or even reversed net impacts of conservation efforts. We develop an economic framework to describe how the intended im...

Tens of thousands of species are threatened with extinction as a result of human activities. Here we explore how the extinction risks of terrestrial mammals and birds might change in the next 50 years. Future population growth and economic development are forecasted to impose unprecedented levels of extinction risk on many more species worldwide, especially the large mammals of tropical Africa, Asia and South America. Yet these threats are not inevitable. Proactive international efforts to incre...

The term “environmental problem” exposes a fundamental misconception: Disruptions of Earth’s ecosystems are at their root a human behavior problem. Psychology is a potent tool for understanding the external and internal drivers of human behavior that lead to unsustainable living. Psychologists already contribute to individual-level behavior-change campaigns in the service of sustainability, but attention is turning toward understanding and facilitating the role of individuals in collective and c...

Ecosystems are self-regulating systems that provide societies with food, water, timber, and other resources. As demands for resources increase, management decisions are replacing self-regulating properties. Counter to previous technical approaches that applied simple formulas to estimate sustainable yields of single species, current research recognizes the inherent complexity of ecosystems and the inability to foresee all consequences of interventions across different spatial, temporal, and admi...

Global food consumption drives irrigation for crops, which depletes aquifers in some regions; here we quantify the volumes of groundwater depletion associated with global food production and international trade.

Food production causes a third of global greenhouse gas emissions. This life-cycle assessment of the supply chain of a loaf of bread finds that over half of its environmental impacts arise from wheat cultivation, with 40% from the use of nitrate fertiliser.

This paper outlines the development of an integrated interdisciplinary approach to agri-food research, designed to address the ‘grand challenge’ of global food security. Rather than meeting this challenge by working in separate domains or via single-disciplinary perspectives, we chart the development of a system-wide approach to the food supply chain. In this approach, social and environmental questions are simultaneously addressed. Firstly, we provide a holistic model of the agri-food system, w...

The absence of integrated decision-making across the agri-food system is arguably the single biggest obstacle to global food security and breaking through it is perhaps our biggest challenge. To date little research has been done which takes a fully integrated view to address this global challenge. Integrated decision making implies change across all parts of the diverse agri-food system, requiring an integrated assessment of all the processes involved from the ecology of the land through to nut...

Improvements in nitrogen use efficiency in crop production are critical for addressing the triple challenges of food security, environmental degradation and climate change. Such improvements are conditional not only on technological innovation, but also on socio-economic factors that are at present poorly understood. Here we examine historical patterns of agricultural nitrogen-use efficiency and find a broad range of national approaches to agricultural development and related pollution. We analy...

We refine the information available through the IPCC AR5 with regard to recent trends in global GHG emissions from agriculture, forestry and other land uses (AFOLU), including global emission updates to 2012. Using all three available AFOLU datasets employed for analysis in the IPCC AR5, rather than just one as done in the IPCC AR5 WGIII Summary for Policy Makers, our analyses point to a down-revision of global AFOLU shares of total anthropogenic emissions, while providing important additional i...

Abstract There is growing international consensus that current patterns of food consumption are not sustainable and global change is needed. Understanding the mechanisms for a transition towards more sustainable diets requires systematic temporal monitoring at the individual or household level. Whilst many countries collect panel data on food expenditure and dietary intake, these datasets are often not designed to monitor progress towards dietary sustainability, therefore using them to understan...

: All over the world, there are species which may be considered as neglected or underutilized despite their nutritious properties. At present, such crops contribute to food security in isolated areas by providing energy and nutrients in a diversified diet. Such genetic heritage—improved by ancient cultures—is under threat of losing biodiversity as well as the traditional knowledge associated with their cultivation and usage. Among these species, the Andean root and tuber crops (ARTCs) constitute...

Achieving global food security requires a new approach that integrates not only all aspects of the growing, harvesting and processing of food (necessary to ensure sufficient affordable and sustainable production to alleviate hunger) but also the complexities associated with food consumption including deterring unhealthy overconsumption. Inefficiencies occur at various points along the agri-food supply chain but at present they are inadequately conceptualized via separate accounts of food loss, f...

The increasing frequency of extreme weather events, urban air pollution, and contamination of oceans by plastic waste have dramatically increased awareness that human civilization faces an existential environmental crisis. Here, we argue that the way humankind views its place on planet Earth is the cause of this crisis and of the reluctance to take meaningful and urgent action. This view gives humans the right to exploit everything on Earth for their own benefit and a belief that sustainability ...

Abstract Background Humanity's current use of resources is not in line with the goal of sustainable development. Climate change impact scenarios appear worryingly pessimistic. The agricultural and food production accounts for a particularly high share of the impact, and this also holds for consumption of food. Transforming food consumption plays a crucial role in tackling the challenges, and sensory consumer science can contribute to this. Scope and approach This commentary examines what is requ...

Edible microbial biomass derived from bacteria, yeasts, filamentous fungi or microalgae is a promising alternative to conventional sources of food and feed. Microorganisms are a good source of protein, vitamins and, in some cases, also contain beneficial lipids. The ability of microorganisms to use simple organic substrates for growth permits industrial-scale cultivation of edible microbial biomass in geographical locations that would not compete with agricultural production. Only a handful of m...

Abstract Food waste prevention has become an issue of international concern, with Sustainable Development Goal 12.3 aiming to halve per capita global food waste at the retail and consumer levels by 2030. However there is no review that has considered the effectiveness of interventions aimed at preventing food waste in the consumption stages of the food system. This significant gap, if filled, could help support those working to reduce food waste in the developed world, providing knowledge of wha...

We assess whether arbuscular mycorrhizal fungi (AMF) improve growth, nutritional status, phenology, flower and fruit production, and disease resistance in woody perennial crops using apple (Malus pumila) as a study system. In a fully factorial experiment, young trees were grown for three years with or without AMF (Funneliformis mosseae and Rhizophagus irregularis), and with industrial standard fertiliser applications or restricted fertiliser (10% of standard). We use two commercial scions (Dabin...
