Arctic ecosystems are threatened by pollution from recently detected extreme atmospheric nitrogen (N) deposition events in which up to 90% of the annual N deposition can occur in just a few days. We undertook the first assessment of the fate of N from extreme deposition in High Arctic tundra and are presenting the results from the whole ecosystem 1...

The issues of food loss and waste (FLW) in the global supply chains have recently gained attention. However, causes for FLW and their mitigation strategies for curbing FLW at different stages of the supply chains remains under researched. Our research aims to address these research gaps in a three-fold way: i), we identified key causes (through roo...

Humanitarian supply chain (HSC) research is still in its infancy and remains an enigma, due to its profound differences with the much-researched field of global supply chains. Thus, humanitarian operations (HO) remain obstinately difficult to manage, despite attempts by key stakeholders to keep abreast of all the contemporary challenges. A key conc...

Circular economy is a theoretical concept that is widely discussed in recent literature as a way to achieve increased sustainability. However, published literature focuses on how to increase circularity without analysing the status quo of circularity, which necessitates answering the question of how to measure the effectiveness of any actions imple...

Food supply chains are receiving increased attention due to the rapid depletion of natural resources, increasing quality standards and rising food safety and security concerns regarding contamination and fraud. Implementing sustainability practices in food supply chains is believed to overcome emerging challenges at both regional and global levels....

This dataset contains 706 estimates of the economic value of water; it has been compiled from published sources. Economic values are provided for three off-stream uses (agriculture/irrigation, industry, and municipal) and three in-stream ecosystem services (recreation, waste assimilation, and wildlife habitat). The dataset covers per period and cap...

Purpose The water footprint provided a full methodology to operationalise the virtual water concept (the volume of water used along a supply chain to produce products and services). A key theme in the water footprint literature is the efficient allocation of water resources at the global scale given the feasibility of trading water intensive commod...

In this paper, we employ a new approach to assessing the impact and efficiency of virtual water use along the supply chain. This approach involves estimating the economic value of virtual water flows. A realistic tea supply chain case study is presented to test this new approach and compare it with alternative volumetric and stress-weighted methods...

The rise of palm oil as the world's most consumed vegetable oil has coincided with exponential growth in palm oil research activity. Bibliometric analysis of research outputs reveals a distinct imbalance in the type of research being undertaken, notably a disproportionate focus on biofuel and engineering topics. Recognizing the expansion of oil pal...

Competitive landscape, informed consumers and stringent regulations have forced many manufacturing small and medium-sized enterprises (SMEs) to focus on operational efficiency along with sustainability issues in recent years. While many manufacturing organisations have been taking lean initiatives for the past few years for operational excellence,...

Sustainability accounting has become a mainstream practice for a large majority of S&P500 companies, and this reflects global society's increasing interest and concern around sustainability issues. In particular, the United Nations published its “Transforming Our World: The 2030 Agenda for Sustainable Development,” and 193 countries signed up to ac...

In this commentary, we set out the rationale for bringing together two research fields: Water Footprint Assessment and environmental (economic) valuation, which have evolved separately. This has the potential to inform the efficient allocation of virtual water flows at a global scale. It would also address some of the aims and objectives in the Wat...

Drawing on theories of acculturation and information diffusion, this paper examines whether social media usage, intergroup contacts and information dissemination influence the cultural adaptation of three ethnic groups, and its implications on sustainable consumption behaviour. Twenty-four semi-structured interviews containing multiple dimensions o...

Economic, social and environmental requirements make planning for a sustainable electricity generation mix a demanding endeavour. Technological innovation offers a range of renewable generation and energy management options which require fine tuning and accurate control to be successful, which calls for the use of large-scale, detailed datasets. In...

Professor Sarah Bridle, Principle Investigator for the STFC Food Network+, describes the launch of the Network and its ambitions to apply the skills and facilities of the Science and Technology Facilities Council to tackling the challenges facing food supply. The Science and Technology Facilities Council (STFC) Food Network+ (SFN) was created in or...

Purpose: Food supply chain in Greece is dominated by SMEs, who face several challenges in adopting green practices. This research attempts to identify the key drivers and barriers influencing the environmental performance of SMEs within the Greek dairy supply chain. Design/methodology/approach: Descriptive research methodology attempts to priorit...

BEFORE constructing a new house, most of us fill the land to protect the building from possible water logging or flooding in future. However, if chances of imminent flooding or water logging loom large over a nation or an island, it will be impossible to adopt the same method for protection. The Small Islands Developing States (SIDS) currently face...

Arctic ecosystems are threatened by pollution from extreme atmospheric nitrogen (N) deposition events in which up to 80% of the total annual N deposition can occur in just a few days. These events are now occurring due to an increase in the long-range transport of reactive N species from pollution sources at lower latitudes, and exacerbated by incr...

Arctic ecosystems are threatened by pollution from both chronic and acute, extreme atmospheric N depositions. Here we report the difference in N (15 N) recovery from the first-ever field simulation of extreme N deposition events (short-term) and snowpack chronic N deposition after 10-years (long-term), within the plant-soil system in the high arcti...

Arctic ecosystems are threatened by pollution from acute, extreme atmospheric N deposition events. Such events can deposit ~40% (perhaps reaching 80%) of annual atmospheric N input as acidic rainfall (pH 4) in less than a week. These events are a result of polluted air masses from the mid-latitude travelling to the high-latitude with minimal disper...
