Methodology for environmental assessment of agri-environment schemes: the Agri Environmental Footprint Index

End of project reportAgri-environment schemes pay farmers for the provision of environmental services. Such schemes tend to have multiple measures that deliver multiple environmental objectives, and there is a lack of consistent methodology with which to measure the environmental benefits of such schemes. Funded by EU FP6, the Agri-Environment Footprint project (www.footprint.rdg.ac.uk) aimed to address this challenge, and this report provides results from selected components of the project.European Unio

Slogans With Negations’ Effect on Sustainable Luxury Brand

The integration of sustainability within luxury brands is of increasing concern to practitioners and academics alike. Thus, it is important to consider how brands can develop effective communication strategies to promote sustainable luxury brands, particularly among an increasingly skeptical consumer base. This research thus investigates the impact of advertising slogans with negations (vs. affirmations) in this regard. Three experimental studies show that advertising slogans with negations (vs. affirmations) increase brand trustworthiness (Studies 1 and 3) and favorable brand attitudes (Studies 1 and 2) among consumers with high levels of skepticism. Notably, this effect is driven by an increased cognitive flexibility (Study 3). The findings of this research can assist sustainable luxury brand managers in developing effective communication strategies to increase favorable consumer responses to sustainable luxury brands

Prosumers in times of crisis: definition, archetypes and implications

Purpose: This paper defines prosumers in light of the COVID-19 crisis and other contexts. It addresses how prosumers helped overcome challenges caused by COVID-19 and is the first paper to develop a taxonomy of prosumers, their differentiating characteristics and the degree to which they are useful in overcoming the challenges of COVID-19. Design/methodology/approach: We conducted a literature search of the prosumer literature using the Web of Science and Scopus databases. Findings: This study solves a definitional dilemma of prosumers and develops six prosumer archetypes displaying the nuances of prosumers. The study shows that the six prosumer archetypes vary in their usefulness in addressing challenges caused by COVID-19. The findings demonstrate the micro (individual), meso (organizational) and macro (societal) benefits offered by prosumers in times of crises. Research limitations/implications: This study has some clear implications for the prosumer literature, the services literature and the crisis literature by clarifying the role of prosumers in times of crisis. Practical implications: This paper offers several implications at the micro (individual), meso (organizational), and macro (societal) levels that are offered by prosumers in times of crises. The benefits of prosumers afford individuals, service practitioners and other organizations ways to remain resilient and strong in the face of significant crises such as COVID-19. Originality/value: This paper makes three specific contributions. First, it contributes to the service literature by highlighting the role and value of prosumers in crises, an area currently under-researched. Secondly, it developed six prosumer archetypes displaying the nuances of prosumers, contributing to the prosumer literature by sharpening the focus of this versatile phenomenon and demonstrating the differential value of each type of prosumer in times of crises. Lastly, the study advances the prosumer literature by resolving the definitional dilemma of prosumers and by providing a broad, yet specific definition of prosumers that captures the different perspectives evident in the prosumer literature

Why do consumers become providers? Self-determination in the sharing economy

Purpose: The purpose of this paper is to explore why and how sharing economy users switch from consumer (e.g. Airbnb guest) to provider (e.g. Airbnb host), and how this helps enrich self-determination theory. Design/methodology/approach: The authors conducted an exploratory study with users who had been consumers (i.e. Airbnb guests) and had switched to being providers (i.e. Airbnb hosts). Findings: Consumers switch to being providers across four phases: “catalysts”, “enablers”, “drivers” and “glue”. The authors identify various extrinsic and intrinsic motivations unique to the switch and map these against motivators postulated by self-determination theory. Research limitations/implications: The authors propose a four-phase process through which consumers become providers. The present study enriches self-determination theory by showing how users' psychosocial needs are addressed through a variety of intrinsic and extrinsic factors that are unique to the role switch. The authors further show how the importance of the three key psychosocial self-determination needs varies through the switch process, thus providing a more nuanced understanding of users' drive for self-determination. Practical implications: This study offers several recommendations to help sharing economy platforms improve their processes and communication to encourage a greater number of consumers to switch roles and become providers. These recommendations address two aspects: (1) encouraging consumers to switch roles and become providers (i.e. acquisition) and following this (2) encouraging providers to continue to perform that role (i.e. retention). Originality/value: Much research has investigated why users become consumers (e.g. Airbnb guests) or providers (e.g. Airbnb hosts) in the sharing economy. However, research to date has not fully embraced the two-sided nature of the sharing economy. Therefore, this is the first paper to explore why and how consumers switch roles and become providers in the sharing economy, and how this helps enrich self-determination theory

Defining freshwater as a natural resource: a framework linking water use to the area of protection natural resources

© 2019, Springer-Verlag GmbH Germany, part of Springer Nature. Purpose: While many examples have shown unsustainable use of freshwater resources, existing LCIA methods for water use do not comprehensively address impacts to natural resources for future generations. This framework aims to (1) define freshwater resource as an item to protect within the Area of Protection (AoP) natural resources, (2) identify relevant impact pathways affecting freshwater resources, and (3) outline methodological choices for impact characterization model development. Methods: Considering the current scope of the AoP natural resources, the complex nature of freshwater resources and its important dimensions to safeguard safe future supply, a definition of freshwater resource is proposed, including water quality aspects. In order to clearly define what is to be protected, the freshwater resource is put in perspective through the lens of the three main safeguard subjects defined by Dewulf et al. (2015). In addition, an extensive literature review identifies a wide range of possible impact pathways to freshwater resources, establishing the link between different inventory elementary flows (water consumption, emissions, and land use) and their potential to cause long-term freshwater depletion or degradation. Results and discussion: Freshwater as a resource has a particular status in LCA resource assessment. First, it exists in the form of three types of resources: flow, fund, or stock. Then, in addition to being a resource for human economic activities (e.g., hydropower), it is above all a non-substitutable support for life that can be affected by both consumption (source function) and pollution (sink function). Therefore, both types of elementary flows (water consumption and emissions) should be linked to a damage indicator for freshwater as a resource. Land use is also identified as a potential stressor to freshwater resources by altering runoff, infiltration, and erosion processes as well as evapotranspiration. It is suggested to use the concept of recovery period to operationalize this framework: when the recovery period lasts longer than a given period of time, impacts are considered to be irreversible and fall into the concern of freshwater resources protection (i.e., affecting future generations), while short-term impacts effect the AoP ecosystem quality and human health directly. It is shown that it is relevant to include this concept in the impact assessment stage in order to discriminate the long-term from the short-term impacts, as some dynamic fate models already do. Conclusions: This framework provides a solid basis for the consistent development of future LCIA methods for freshwater resources, thereby capturing the potential long-term impacts that could warn decision makers about potential safe water supply issues in the future

The synthesis of the rhamnogalacturonan II component 3-deoxy-D-manno-2-octulosonic acid (Kdo) is required for pollen tube growth and elongation

Despite a very complex structure, the sugar composition of the rhamnogalacturonan II (RG-II) pectic fraction is extremely conserved. Among its constituting monosaccharides is the seldom-observed eight-carbon sugar 3-deoxy-D-manno-octulosonic acid (Kdo), whose phosphorylated precursor is synthesized by Kdo-8-P synthase. As an attempt to alter specifically the RG-II structure in its sugar composition and assess the consequences on the function of RG-II in cell wall and its relationship with growth, Arabidopsis null mutants were sought in the genes encoding Kdo-8-P synthase. Here, the isolation and characterization of one null mutant for the isoform 1 (AtkdsA1-S) and two distinct null mutants for the isoform 2 of Arabidopsis Kdo-8-P synthase (AtkdsA2-V and AtkdsA2-S) are described. Evidence is provided that AtkdsA2 gene expression is preferentially associated with plantlet organs displaying a meristematic activity, and that it accounts for 75% of the mRNAs to be translated into Kdo-8-P synthase. Furthermore, this predominant expression of AtKDSA2 over AtKDSA1 was confirmed by quantification of the cytosolic Kdo content in the mutants, in a variety of ecotypes. The inability to identify a double knockout mutant originated from pollen abortions, due to the inability of haploid pollen of the AtkdsA1- AtkdsA2- genotype to form an elongated pollen tube properly and perform fertilization

Public policy and future mineral supplies

A widespread and pessimistic view of the availability of mineral commodities calls for strong government initiatives to ensure adequate future supplies. This article provides a more market oriented and optimistic perspective, one that focuses on production costs and prices rather than physical availability. It sees short-run shortages continuing to plague commodity markets in the future as in the past. Though painful while they last, these shortages are temporary and do not pose a serious long-run threat to human welfare. Moreover, even without government intervention, they self-correct. The sharply higher prices that they evoke create strong incentives that foster supply and curb demand. Potentially more serious are long-run shortages due to mineral depletion. Such shortages are often thought to be inevitable, a conclusion that flows directly from the physical view of depletion. For various reasons, we reject this view of depletion in favor of an economic view. The latter recognizes that depletion may create long-run shortages, but stresses that this need not be the case if new technology can continue to offset the cost-increasing effects of depletion in the future as it has in the past. The economic view also suggests that a list of mineral commodities most threatened by depletion can best be compiled using cumulative availability curves rather than the more common practice of calculating commodity life expectancies based on estimates of available stocks.<p>Validerad;2018;Nivå 2;2018-08-08 (rokbeg)</p
