State of the art in S-LCA: integrating literature review and automatic text analysis

Purpose

Social life cycle assessment (S-LCA) method lacks of standard and code of practice. The aim of the study is to classify the wide variety of contributions on S-LCA for tracking the development of different themes and for defining and classifying the main approaches in a systematic and reproducible way.

Methods

The research addressed to study a collection of 51 articles published between January 2006 and November 2014 using statistical criteria. We used automatic text analysis (ATA) tools related to lexicon analysis to identify keywords useful in tracing the main topics covered in articles published in different periods. We conducted principal component analysis (PCA) to classify the different approaches in the literature and to outline the orientations of the various research groups.

Results and discussion

The results from lexicon analysis showed a rapid succession of different topics covered in the analyzed period. This alternation is strongly affected by the introduction of UNEP/Society of Environmental Toxicology and Chemistry (SETAC) S-LCA guidelines and methodological sheets. PCA analysis enabled to synthesize the information related to the numerous approaches. Results did not show a clear division into groups which indicates the absence of a dominant position on the subject in the literature.

Conclusions

This study attempted to map the state of art in S-LCA integrating literature review with multivariate statistical techniques. The analysis showed a highly fragmented field. These results confirm the existence of a variety of approaches that in part have already been identified by literature reviews on S-LCA. Alignment with the results in the literature confirms ATA to be a suitable instrument for the realization of reviews. Moreover, being systematic and reproducible allows ATA to be applied repeatedly, expanding the number of articles and topics analyzed.

人类福祉研究进展——基于可持续科学视角

人类福祉的研究兴起于20世纪50年代。在过去的十几年中,人类福祉与生态系统服务一并成为可持续科学的核心概念,发展迅速。不同学科背景的研究者逐渐认识到仅仅依靠经济指标无法恰当地评估人类福祉,经济发展只是实现可持续发展目标的手段,而提高人类福祉才是其核心所在。人类福祉研究为评估个人福祉和国家社会的群体福祉提供概念框架和测量方法,服务于政府决策。自2005年联合国组织的《千年生态系统评估》报告明确提出生态系统服务与人类福祉的关系以来,人类福祉的研究进入了快速发展的新阶段。近年来,国内外越来越多的学者从可持续科学的视角对人类福祉开展研究。与国际同行的工作相比,我国人类福祉研究集中于可持续科学视角下对福祉的定量化评估,而各学科之间,尤其是自然科学和人文与社会科学之间的交流合作相对较少。回顾了人类福祉研究的历史发展,及其在可持续科学视角下的新进展,具体包括:客观福祉,主观福祉,生态系统服务与人类福祉关系。最后,讨论了人类福祉研究的主要议题,以及我国人类福祉研究未来的发展方向。     

The phantom chorus: birdsong boosts human well-being in protected areas

Spending time in nature is known to benefit human health and well-being, but evidence is mixed as to whether biodiversity or perceptions of biodiversity contribute to these benefits. Perhaps more importantly, little is known about the sensory modalities by which humans perceive biodiversity and obtain benefits from their interactions with nature. Here, we used a ‘phantom birdsong chorus'' consisting of hidden speakers to experimentally increase audible birdsong biodiversity during ‘on'' and ‘off'' (i.e. ambient conditions) blocks on two trails to study the role of audition in biodiversity perception and self-reported well-being among hikers. Hikers exposed to the phantom chorus reported higher levels of restorative effects compared to those that experienced ambient conditions on both trails; however, increased restorative effects were directly linked to the phantom chorus on one trail and indirectly linked to the phantom chorus on the other trail through perceptions of avian biodiversity. Our findings add to a growing body of evidence linking mental health to nature experiences and suggest that audition is an important modality by which natural environments confer restorative effects. Finally, our results suggest that maintaining or improving natural soundscapes within protected areas may be an important component to maximizing human experiences.     

Human well-being differs by community type: Toward reference points in a human well-being indicator useful for decision support

Human activity has growing impacts on the natural capital humans depend on for existence. While many of these impacts are regional, national, or international in scope, it is increasingly evident that decisions made at the local community level are also important. Yet, understanding the impacts of local decisions, as well as how to correct or mitigate these impacts, can be problematic, as communities differ in resources, priorities, dependencies on natural capital, and even opinions about whether these impacts actually affect quality of life. Every community has unique characteristics, however effective decision support at the community level requires common reference points in measures of human well-being upon which to base decision support. We have developed a community classification system that is intended to find such common ground in community characteristics and tie these common elements to measures of human well-being. This community classification system was developed in the USA with publically available data on resource dependence, socio-economic composition, and existence of natural capital. The resulting classification was applied to coastal communities at the county level and then used to predict human well-being based on an existing human well-being index. Coastal communities were separated into eight characteristics groups based on Bayesian cluster analysis. Classification groups were found to be associated with significant differences in human well-being. More importantly, significant differences in specific elements of well-being were associated with key community characteristics, such as population density and economic dependence on local natural resources. In particular, social cohesion and the leisure time were strong elements of well-being in low density communities with high natural resource dependence but this association weakened as population densities and economically diversity increased. These sorts of commonalities in community type that can be tied to differences in human well-being are important because they provide clear ties to environmental service flows, as well as a meaningful reference point from which to measure the local impacts of decisions as changes in community-specific human well-being.     

Enhancing comprehensive measurement of social impacts in S-LCA by including environmental and economic aspects

Purpose

Measurability becomes a key question in the assessment of the sustainability of products and services. As the LCA has proven its capability of measuring environmental sustainability over the last decades, the Social Life Cycle Assessment (S-LCA) seems promising as a way to cover the social dimension of sustainability within a similar framework. For operability reasons, working hours are commonly used as a single metric in product orientated S-LCA studies, even though major stakeholder groups are excluded by doing so. This paper shows how this shortcoming can be overcome through the introduction of the measurement of additional activity variables and explores different ways of implementing these variables.

Methods

This work suggests introducing the activity variables Biophysical Pressure and Added Value in addition to the commonly used working hours of involved labour forces. Biophysical Pressure reflects the negative influence of the degraded natural environment on the affected humans in addition to the direct health effect covered by standard LCA. Added Value represents the potential benefits for stakeholders due to financial investments in production. The new activity variables are derived from the MRIO database “Exiobase” and coupled with social risk indicators from the “Social Hotspot Database”. Finally, the qualitative risk classes are transformed to quantitative units and normalized to allow for a better interpretation and an optional aggregation of the three variables into a Final Social Impact score.

Results and discussion

In order to test the method’s applicability, the social impacts of products and services from two different product systems were calculated and compared. Three t-shirts and four residential housing heating systems were assessed by the developed method and compared on the basis of their respective functional units. Major differences between the social impact measured only by working hours and social impact measured by the aggregation of the three quantitative units were observed, especially since the Added Value (social benefits) dimension and working hours contrasted regionally. While the concept is functional, there are limitations related to the MRIO inventory data and to the interpretation of results; therefore, sensitivity analyses were applied.

Conclusions

The developed S-LCA method shows a promising way to extend the range of stakeholders affected by the life cycle of a distinct product by adding new variables. While constraints of MRIO data concerning detailed product system representation currently limit the approach, it allows one to identify potential social hotspots in complex product systems.

     

Global alteration of freshwaters: influences on human and environmental well-being

Human and environmental well-being—including disease resistance or avoidance, good nutrition, and species-appropriate population dynamics—are congruent with sustained healthy conditions. Unfortunately, hydrological alterations designed to benefit human societies often have unintended—and sometimes severe—consequences for the environment and the biodiversity it supports, and hence affecting billions of people. Improving this situation necessitates new water-resource developments, better water-use efficiency, and a reduction of contamination. Overall, the influences of existing and future freshwater (FW) regimes on human and environmental well-being are varied and wide-ranging. Furthermore, the scale is daunting: >1 billion people currently live in basins likely to require river management interventions for climate change alone. Global declines in FW biodiversity, in the nutritional value, and abundance of harvestable FW and riparian products, as well as deterioration in habitat quality for many species, require solutions; as do ongoing increases in the spread of FW-related diseases and non-native species. Modifications to FWs are now manifested in population declines and non-sustainable demographics for many aquatic species, as well as in deterioration of human health. In response, scientists, policy-makers, and water users are beginning to conceptualize FWs in terms of a global water system (GWS) to better understand and manage anthropogenic impacts. This involves identifying the ecological and policy implications of changes to the GWS, establishing international programs to understand and resolve major social and environmental issues arising from those changes, and developing broad-based mitigation or restoration techniques (e.g., environmental flow methodologies). Achieving these goals is paramount for maintaining human health as well as for the FW ecosystems upon which we depend.     

The importance of human FcgammaRI in mediating protection to malaria

The success of passive immunization suggests that antibody-based therapies will be effective at controlling malaria. We describe the development of fully human antibodies specific for Plasmodium falciparum by antibody repertoire cloning from phage display libraries generated from immune Gambian adults. Although these novel reagents bind with strong affinity to malaria parasites, it remains unclear if in vitro assays are predictive of functional immunity in humans, due to the lack of suitable animal models permissive for P. falciparum. A potentially useful solution described herein allows the antimalarial efficacy of human antibodies to be determined using rodent malaria parasites transgenic for P. falciparum antigens in mice also transgenic for human Fc-receptors. These human IgG1s cured animals of an otherwise lethal malaria infection, and protection was crucially dependent on human FcgammaRI. This important finding documents the capacity of FcgammaRI to mediate potent antimalaria immunity and supports the development of FcgammaRI-directed therapy for human malaria.     

Mutagenic activity as a parameter to assess ambient air quality for protection of the environment and human health

Atmospheric pollution has significant effects on maintaining the integrity of ecosystems and on the population's quality of life. Epidemiological studies have clearly associated related health problems, especially respiratory diseases, with exposure to air pollution. Organic compounds adsorbed to the airborne particulate matter are mutagenic in the Salmonella/microsome assay, and a considerable number of them are known to be carcinogenic to rodents. Studies performed at four sites within the urban area of Porto Alegre, capital of the state of Rio Grande do Sul, identified higher mutagenic activity at the sites with heavier vehicle traffic in assays without and with metabolic activation. The responses varied at different seasons of the year, and the highest revertants per cubic meter (rev/m(3)) values were observed in spring for moderately polar compounds, and in summer for non-polar ones. A pilot study was also performed in the region under the influence of a industrial petrochemical area. Most of the sites studied within the industrial area, as compared to others sampled in the nearby environment, presented higher levels of mutagenic activity independent of total suspended particulates (TSP) concentration in the sample. In the urban and industrial regions, the observed mutagenic activities were strongly associated with the presence of polycyclic aromatic hydrocarbons (PAHs). The responses observed in the TA98NR and TA98/1,8-DNP(6) strains suggest the activity of nitrocompounds in both studies. The Salmonella/microsome assay is a sensitive method to define areas contaminated by these compounds, even in samples with TSP values that are consistent with the legal environmental quality standards.
