Corporate social responsibility: sustainable water use

Freshwater scarcity is no longer limited to sub-Saharan developing countries; also in Western society, access to unlimited amounts of freshwater is not assured at all times. It has been argued - and laid down in many national legal systems - that access to freshwater is a basic human right. What if corporate freshwater use threatens to interfere with this human right? The main focus of the article is to explore the role of today’s companies in relation to freshwater. A number of tools have been developed to attend to the necessity to reduce corporate use of freshwater. The article discusses specialised water reporting instruments such as the 2007 Global Water Tool and the ‘water footprint’ calculation method. In addition, attention is paid to a CERES report (2010) revealing that the majority of the 100 world’s leading companies in water-intensive industries still has weak management and disclosures of water-related risks and opportunities. To obtain concrete information about corporate water strategies and practices, an explorative analysis was conducted on 20 Dutch multinational companies. The article highlights various innovative practices. In sum, it is demonstrated that companies are expected to bear responsibility for their impact on water resources, in particular when it influences public access to water in areas with freshwater scarcity and/or weak government. Notwithstanding the critical conclusions of the CERES report, it is interesting to see an evolution in corporate research concerning sustainable water use and the development of greener products and greener ways of production.     

Estuarine surface water allocation: A case study on the interactive role of science in support of management

The inevitable need for freshwater to support the projected population growth along the ocean coast is an emerging issue of potential consequence to adjacent estuaries. A large and controversial water withdrawal/reservoir project in Virginia's coastal plain was the basis of science–management interactions that quantified the vulnerability of tidal freshwater nekton for a series of water withdrawal scenarios. Through progressive iterations of the regulatory review process, which in Virginia includes academic reviews of all aspects of projects proposed to affect the marine and estuarine environment, we developed a novel approach to modeling entrainment probabilities applicable to situations that lack a locally validated hydrodynamic model. The science/management interplay ultimately resulted in surface water allocation strategies that are balances to society and the affected natural environment. Model results showed that the probability of encounter (contact between an egg or larva and one or more units of the intake array) ranged from 1.71% under the conditions of a high river flow and low withdrawal rate to 99.99% under the conditions of a low river flow and high withdrawal rate. The collective body of scientific information was incorporated into regulatory conditions placed on water withdrawals that are designed to protect at least 95% of early life history stages within the intake array's zone of influence.     

Stimulating learning and innovation in networks for regional sustainable development: the role of local authorities

Inter-organizational collaboration in networks and partnerships is supposed to promote the potential for learning and innovation needed for environmental transformation and sustainable development. This paper aims at exploring the roles of local authorities (LAs) in actor-networks related to regional sustainable development, and examining their potential in stimulating learning and innovation related to sustainable development. From empirical case studies it is suggested that LAs can act as ‘teachers’ or ‘tutors’ in the networks. From further analysis, drawing also from literature on partnerships, innovation management, socio-technical change, and educational science, it is proposed that in the short run both the ‘teacher’ and ‘tutor’ approach would promote incremental innovation rather than the radical system innovations needed for sustainable development. However, there is potential for stimulating more long-term, radical change if the LA takes on the role of a ‘teacher’. This approach may favour close collaboration in long-lived, multi-actor networks with potential to (i) serve as forum for continuous dialogue on sustainable development at a community level, (ii) stimulate experimentation and learning needed for system innovations, and (iii) provide a basis for strategic niche management for development and testing of new technologies.     

Harnessing expert-based information for learning and the sustainable management of complex socio-ecological systems

Human-used and managed natural resources, such as watersheds, represent complex socio-ecological systems where learning from different knowledge sources is essential for sustainable management. Guided by the advocacy coalition framework, the paper presents a set of propositions that help explain the different functional uses of expert-based information, the network position of scientific experts, and learning within and between coalitions. Most importantly, the paper investigates common assumptions about the superiority of consensus-based institutions for integrating science into policy-making by examining two collaborative and two adversarial policy subsystems. The findings show that the scientists’ centrality as coalition allies and opponents is lower in collaborative policy subsystems than in adversarial policy subsystems. The findings suggest a more hospitable setting for learning and sustainability in the management of natural resources in collaborative compared to adversarial subsystems. The paper concludes with suggestions for future research in sustainability and learning.     

The role of knowledge and research in facilitating social learning among stakeholders in natural resources management in the French Atlantic coastal wetlands

Environmental policy development increasingly refers to procedural approaches where local organisational structures are set up to initiate social interactions, to establish common working methods and to formulate collective agreements. In a context of complexity and uncertainty regarding environmental issues at stake, deliberations are mostly about managing interdependencies, i.e., building agreements and implementing changes so as to reconstruct the links between natural, technical and social phenomena. We see these deliberations as situations where social learning occurs; as an iterative process of knowledge co-production (i.e., of ‘knowing’) among stakeholders brought into interaction. Our research aims at better understanding these processes in the context of French Atlantic coastal wetlands where multi-stakeholder platforms for decision-making have become the dominant process for implementing natural resources management policies. Our studies focus on the challenge of managing the production and application of knowledge in social settings, in which scientists themselves come to play a role. They show how scientific knowledge can acquire heuristic value when used in the context of intervention research, as well as revealing some of the ethical dilemmas this may pose for the role of researcher.     

Towards sustainable production and use of charcoal in Kenya: exploring the potential in life cycle management approach

The study seeks to demonstrate the potential role that industrial ecology could play towards energy poverty reduction and environmental conservation in Kenya through sustainable charcoal production and consumption. This is achieved through an exploration of the application of the life cycle management (LCM) concept that identifies various opportunities for technological intervention for energy and environmental conservation and reduction of material and energy losses. It also identifies opportunities for income generation at various stages of the product’s life cycle; an aspect critical in poverty reduction in developing countries. The study finds that applying LCM in the charcoal trade in Kenya can deliver social, economic and environmental benefits to developing country communities and should, therefore, be promoted. However, appropriate legal, policy and institutional frameworks must exist in these countries for this to occur.     

Alternative cropping systems for sustainable water and nitrogen use in the North China Plain

Serious water deficits and excessive nitrogen (N) applications are threatening the sustainability of intensive agriculture in the North China Plain (NCP). This study examined the possibility of replacing the conventional system (Con.W/M) of winter wheat (Triticum aestivum L.) and summer maize (Zea mays L.), with an optimized double cropping system (Opt.W/M), a 2-year system (winter wheat/summer maize-spring maize, W/M-M), and a monoculture system (spring maize, M) based on optimal water and N management strategies. From 2004 to 2010, a long-term field experiment conducted in the NCP showed that although >70 mm of irrigation water can be saved with Opt.W/M compared with Con.W/M, annual net groundwater use under Opt.W/M was still 250 mm, 65-90% of which was consumed during the winter wheat season. When wheat production was decreased, 35% and 61% of irrigation water could be reduced in W/M-M and M compared to Con.W/M, respectively. As a result, annual groundwater use was decreased to 190 mm in W/M-M and 94 mm in M. Meanwhile, the N fertilizer rate was reduced 59% and 72% in W/M-M and M compared to Con.W/M, respectively. There were no significant differences in net economic returns between Con.W/M and W/M-M across the 6-year period. In the 6 years, no significant economic loss was observed between Con.W/M and M except in the 2008-2010 rotation. The W/M-M and M systems showed great potential to reduce water and N application and achieve groundwater use balance, and thus should be considered for economic and sustainable agricultural development in the NCP.     

The organisation of social learning in response to perceptions of crisis in the water sector of The Netherlands

This article deals with responses in the Netherlands to a widespread perception within the water sector of crisis, rooted in an appreciation that former ways of managing water could no longer deal with contemporary and possible future events. The crisis and initial responses are first outlined, grounding the SLIM project experience in Dutch water management practice and policy. This leads to the research question formulated by the Dutch SLIM team, and the predictions it gave rise to. The research methodology, case studies and policy analyses at the core of the study are introduced. Empirical observations concerning four aspects of the change process are used to explore the predictions: conflict and confrontation among stakeholders; discovery of interdependence among stakeholders; development of social spaces where stakeholders could encounter each other in shared actions; and the role of facilitators and process leaders in helping stakeholders to go forward. The observations are analysed in relation to the initial predictions and the surprises encountered in the history of the cases. Knowledge management is identified as a key task in the social learning processes analysed. The article concludes with reflections on the role of the environmental sciences in the policy processes and research practices described.     

Resources and waste management in Turin (Italy): the role of recycled aggregates in the sustainable supply mix

The ever increasing quantity of construction and demolition waste (C&DW) in Italy is presently challenging public administrators, which strive to ensure that collection and recycling are sustainably managed and need to understand whether and to what extent recycled aggregates can complement natural aggregates in a sustainable supply mix (SSM) for the construction industry. The paper presents a research aimed at analysing energy and environmental implications of the C&DW recycling chain in the administrative territory of Provincia di Torino in Northern Italy, with 2.25 million inhabitants and yearly generation of 1.8 million tons of C&DW. A combined Geographical Information System (GIS) and Life Cycle Assessment (LCA) model was developed using site-specific data and paying particular attention to land use, transportation and avoided landfill: crucial issues for sustainable planning and management. A GIS was used to handle data and information about 89 recycling plants, including technological features, output and physical–mechanical characteristics of recycled aggregate. The LCA methodology was used to identify and quantify energy and environmental loads, under different assumptions relevant to delivery distances, quality of recycled aggregates, local availability of natural aggregates and geographical coverage of market demand. The C&DW recycling chain was proved to be eco-efficient, as avoided impacts were found to be higher than the induced impacts for 13 out of 14 environmental indicators. It was also estimated that the transportation distance of recycled aggregate should increase 2–3 times before the induced impacts outweigh the avoided impacts.     

Adaptation of land management in the Mediterranean under scenarios of irrigation water use and availability

Meeting the growing demand for food in the future will require adaptation of water and land management to future conditions. We studied the extent of different adaptation options to future global change in the Mediterranean region, under scenarios of water use and availability. We focused on the most significant adaptation options for semiarid regions: implementing irrigation, changes to cropland intensity, and diversification of cropland activities. We used Conversion of Land Use on Mondial Scale (CLUMondo), a global land system model, to simulate future change to land use and land cover, and land management. To take into account future global change, we followed global outlooks for future population and climate change, and crop and livestock demand. The results indicate that the level of irrigation efficiency improvement is an important determinant of potential changes in the intensity of rain-fed land systems. No or low irrigation efficiency improvements lead to a reduction in irrigated areas, accompanied with intensification and expansion of rain-fed cropping systems. When reducing water withdrawal, total crop production in intensive rain-fed systems would need to increase significantly: by 130% without improving the irrigation efficiency in irrigated systems and by 53% under conditions of the highest possible efficiency improvement. In all scenarios, traditional Mediterranean multifunctional land systems continue to play a significant role in food production, especially in hosting livestock. Our results indicate that significant improvements to irrigation efficiency with simultaneous increase in cropland productivity are needed to satisfy future demands for food in the region. The approach can be transferred to other similar regions with strong resource limitations in terms of land and water.     

Project feasibility study: the key to successful implementation of sustainable and socially responsible construction management practice

This paper introduces a new approach for conducting project feasibility study by embracing the principles of sustainable development. Construction projects, in particular, infrastructures have major influence on the attainment of sustainable development, thus project sustainability needs to be considered. This becomes a pressing issue particularly in those developing countries or regions, such as China where a huge amount of construction works are currently performed and remain to happen in the future. Previous study has addressed little on the relevance of project feasibility study to project sustainability performance. The importance of incorporating sustainable development principles in conducting project feasibility study is not effectively understood by project stakeholders. This paper addresses major challenges of undertaking project feasibility study in line with sustainable construction practice with reference to the Chinese construction industry. A case study approach is the major research method in this study. The research team collected 87 feasibility study reports from various projects. Attributes are used for measuring project performance, including 18 economic performance attributes, nine social performance attributes, and eight environmental performance attributes. Research results show that economic performance is given the most concern in the current practice of project feasibility study, whilst less attention is given to the social and environmental performance. The study reveals the insufficiency of examining the performance of implementing a construction project from the perspective of sustainable development. The results also suggest the need for shifting the traditional approach of project feasibility study to a new approach that embraces the principles of sustainable development.     

Enhancing the use of science in environmental policy-making and regulation

Over the last 10 years the UK Government has strongly promoted the more effective use of science to inform policy-making and regulation. In response, the Environment Research Funders’ Forum (which brings together the main UK Governmental funders of environmental research) has carried out studies, reported in this paper, to establish what is working, what is not, and why in respect of the linkage between science and environmental policy-making and regulation.The findings indicated that there was potential to improve effectiveness in: establishment of research questions and agendas, accessing information and expertise, the role of interpreters, and transparency and evaluation. These findings are re-enforced by those of previous studies conducted in the UK and EU. The studies found that current practice in using science to inform policy-making has not yet caught up with guidance, and they identified potential actions that could be taken by the Forum and its members to narrow the gap.     

Explorations on the University's role in society for sustainable development through a systems transition approach. Case-study of the Technical University of Catalonia (UPC)

Focusing on the sustainability challenge, a growing number of Universities are redefining their core strategies in order to adapt to the real social needs and expectations of their stakeholders. Beyond integrating sustainability into the University's internal activities (curriculum, research, operations, etc.), the challenge seems to be integrating the University with the sustainable development paths of society. For the last 10 years the Technical University of Catalonia (UPC) has tackled this challenge through an overarching strategic plan. The latest strategy, UPC Sustainable Plan 2015 has adopted a different focus, which was designed through a participatory approach, involving many internal and external stakeholders.This work aims to use a conceptual framework based on systems transitions to assess the systems change potential of a University strategy, in this case, the sustainability strategy of UPC. The main objectives of this paper are: to present the sustainability strategy participatory design process and its outcomes at UPC; to analyse the strategy change potential through a new transition/systems renewal method that is proposed; and to compare it with the UPCs previous environmental strategy; The work concludes that the systems transition potential is currently higher with the new strategy and discusses the elements that explain this finding.     

Settlement decisions in blue tits: difference in the use of social information according to age and individual success

Dispersers are expected to assess breeding habitat quality before settlement. Although cues reflecting habitat quality are well studied, social cues have not been as well evaluated. In this paper, we studied breeding habitat selection during 3 years in a natural population of blue tits, Cyanistes caeruleus, breeding in nest-boxes. Our aim was to investigate if this species used conspecific density and/or reproductive success of con- and heterospecifics (i.e., social cues) in settlement decisions. The patterns observed were consistent with the idea that juveniles, when dispersing from their natal patches, did not react to any of the cues that we tested. In contrast, breeders that dispersed seemed to respond to both conspecific mean patch reproductive success (PRS) and breeding density of the settlement patch in the year of dispersal, their response differing according to their own reproductive success. Indeed, failed breeders moved to areas with high PRS and low density relative to source patches, while successful breeders behaved the opposite. The comparison between juveniles and adults might be modulated by the limited time available to juveniles to gather information on PRS and density at the end of the dispersing year. Adults lacking these time constraints, however, seemed to rely on these conspecific cues although limited by their own quality. Additionally, breeders were more likely to be immigrants in patches with relatively low breeding success and density the previous year, suggesting that settlement is influenced by multiple cues, which may reveal information on different aspects of habitat and be available at different moments. Collectively, our results support the importance of social cues for blue tits’ settlement.     

Climate policy integration in the land use sector: Mitigation,adaptation and sustainable development linkages

This article re-conceptualizes Climate Policy Integration (CPI) in the land use sector to highlight the need to assess the level of integration of mitigation and adaptation objectives and policies to minimize trade-offs and to exploit synergies. It suggests that effective CPI in the land use sector requires i) internal climate policy coherence between mitigation and adaptation objectives and policies; ii) external climate policy coherence between climate change and development objectives; iii) vertical policy integration to mainstream climate change into sectoral policies and; iv) horizontal policy integration by overarching governance structures for cross-sectoral coordination. This framework is used to examine CPI in the land use sector of Indonesia. The findings indicate that adaptation actors and policies are the main advocates of internal policy coherence. External policy coherence between mitigation and development planning is called for, but remains to be operationalized. Bureaucratic politics has in turn undermined vertical and horizontal policy integration. Under these circumstances it is unlikely that the Indonesian bureaucracy can deliver strong coordinated action addressing climate change in the land use sector, unless sectoral ministries internalize a strong mandate on internal and external climate policy coherence and find ways to coordinate policy action effectively.     

A new way of carbon accounting emphasises the crucial role of sustainable timber use for successful carbon mitigation strategies

The roles of forest management and the use of timber for energy in the global carbon cycle are discussed. Recent studies assert that past forest management has been accelerating climate change, for example in Europe. In addition, the increasing tendency to burn timber is an international concern. Here, we show a new way of carbon accounting considering the use of timber as a carbon neutral transfer into a pool of products. This approach underlines the robust, positive carbon mitigation effects of sustainable timber harvesting. Applying this new perspective, sustainable timber use can be interpreted not as a removal but a prevention of carbon being converted within the cycle of growth and respiration. Identifying timber use as a prevention rather than a removal leads to the understanding of timber use as being no source of carbon emissions of forests but as a carbon neutral transfer to the product pool. Subsequently, used timber will then contribute to carbon emissions from the pool of forest products in the future. Therefore, timber use contributes to carbon mitigation by providing a substantial delay of emissions. In a second step, the carbon model is applied to results of a previous study in which different timber price scenarios were used to predict timber harvests in Bavarian forests (Germany). Thus, the influence of the economic dimension “timber price” on the ecological dimension carbon sequestration was derived. It also shows that these effects are stable, even if an increasing tendency of burning timber products for producing energy is simulated. Linking an economic optimization to a biophysical model for carbon mitigation shows how the impact of management decisions on the environment can be derived. Overall, a sustainably managed system of forests and forest products contributes to carbon mitigation in a positive, stable way, even if the prices for (energy) wood rise substantially.     

Linking academic and local knowledge: community-based research and service learning for sustainable rural development in Hungary

Discussions about the potential role of academic and research institutions in regional sustainability initiatives (RSIs) inevitably raise the issue of the role of science in society in general. In democratic societies, it can be argued that science–society relationships should be based on establishing and institutionalizing mutual dialogues, making public concerns not only visible but the public as equal partner. In order to fulfil the social responsibilities of academic institutions involved in RSIs through establishing dialogues with diverse stakeholders, a possible methodology is conducting participatory action research (PAR) combined with the educational model of service learning. The PAR project reported here aims at facilitating a bottom-up, micro-region level sustainability planning and development process in one of the most socio-economically disadvantaged rural areas of north-east Hungary. Some of the main results of this university–community partnership were its contribution to sustainability, including the activation of local capabilities and networking across various local stakeholder groups through various small-scale projects and the co-production of a socially grounded and landscape-based rural development plan for the micro-region.     

Addressing the dynamics of agri-food systems: an emerging agenda for social science research

The ‘modernist’ project that has come to dominate food and agricultural policy has failed to provide sustainable outcomes for many poor people in developing countries. Conventional agricultural science is not able to explain let alone address these concerns because it is based on a static equilibrium-centred view that provides little insight into the dynamic character of agri-food systems. This paper analyses how prevailing narratives of technological change and economic growth have come to dominate key food and agriculture policy debates. It seeks to counter these orthodox notions by emphasising that agri-food systems are embedded in complex ecological, economic and social processes, and showing how their interactions are dynamic and vulnerable to short-term shocks and long-term stresses like climate change. The paper makes the case for a deeper understanding of diverse ‘rural worlds’ and their potential pathways to sustainability through agriculture. Moreover, it argues for a normative focus on poverty reduction and concern for the distributional consequences of dynamic changes in agri-food systems, rather than aggregates and averages. Finally, it sets out an interdisciplinary research agenda on agri-food systems that focuses on dynamic system interactions in complex, risk-prone environments and explores how pathways can become more resilient and robust in an era of growing risk and uncertainty.     

Challenges of connecting international science and local level sustainability efforts: the case of the Large-Scale Biosphere–Atmosphere Experiment in Amazonia

The Large-Scale Biosphere–Atmosphere Experiment in Amazonia (LBA) is a multi-year Brazil-led international environmental science experiment funded by the U.S. National Aeronautics Space Administration, the European Union and Brazil. It is intended to inform decision making under the United Nations Framework Convention on Climate Change (UNFCCC) as well as Brazilian national environmental decision-making related to the Amazon region. Focused on the Amazon region, and primarily on the Brazilian Amazon, the LBA is a case study in issues that can arise when doing globally oriented research in a less developed country setting and a test of assumptions that such research simultaneously benefits global and local levels. This article offers a qualitative evaluation of the extent to which the LBA has achieved its goals and identifies structural obstacles within science that must be overcome to improve the fit between international science programs and efforts to nurture more sustainable use of natural resources in a less developed country.
