Backcasting

Water management strategies in times of global change need to be developed within a complex and uncertain environment. Scenarios are often used to deal with uncertainty. A novel backcasting methodology has been tested in which a normative objective (e.g. adaptive water management) is backcasted within the context of exploratory scenarios that sketch four different plausible futures (Economy First, Policy Rules, Fortress Europe, and Sustainability Eventually). The main advantage of combining exploratory and normative scenarios is in the identification of robust actions: actions that are effective in the different socio-environmental contexts sketched in the exploratory scenarios. This paper has three objectives: (1) to present the methodology, focussing on its novel aspects (2) to test the methodology and evaluate its perceived success by analysing organiser and stakeholder feedback and (3) to analyse and evaluate the results, in order to study the impact of the exploratory scenarios on the backcasting results and the added value of robust actions. The methodology was successfully tested in 9 local and one regional case study in a water project (SCENES). Results showed that the exploratory scenarios influenced the content of the backcasts, thus making the identification of robust strategies possible. The list of robust strategies includes both technological and social/organisational strategies, highlighting the need for an integrated approach. The approach shows high potential, but as the methodology is in its infancy more research is needed, particularly in methods to facilitate and monitor information flow between exploratory scenarios and backcasts.

This paper outlines an emerging Transition Design approach for addressing " wicked " problems (such as climate change, loss of biodiversity, crime, poverty, pollution, etc.) and catalysing societal transitions toward more sustainable and desirable futures. Wicked problems are " systems problems " that exist within large, socio-technical systems and therefore require new problem-solving approaches. The Transition Design Framework brings together an evolving body of practices that can be used to: 1. visualize and " map " complex problems and their interconnections and interdependencies; 2. situate them within large, spatio-temporal contexts; 3. identify and bridge stakeholder conflicts and leverage alignments; 4. facilitate stakeholders in the co-creation of visions of desirable futures; 5. identify leverage points in the large problem system in which to situate design interventions. Rather than a fixed, templatised process, the Transition Design Framework provides a logic for bringing together an evolving set of practices relevant to designing for systems level change. This paper reports on how this approach is being tested on a community based project that was informed by classroom based coursework. A new, design-led approach is needed to address the complex, wicked problems confronting societies in the 21 st century (Hughes & Steffen, 2013; Jensen, 2017) and to seed and catalyse societal transitions toward more sustainable and desirable long-term futures (Porritt, 2013, pp 274-276).

Bottled water emerged as a global phenomenon in the 1970s and has offered an alternative to tap water. In Czech Republic, consumers were used to drinking tap water on a daily basis as there was almost no bottled water on the market prior to 1989. Now, the country has an annual consumption of bottled water around 60 litres per capita. This master thesis looks at the controversy of tap versus bottled water and finds that bottled water may not make sense from an evironmental and financial point of view, but offers consumers a compelling story and convenience. I have selected a small Central Bohemian town of Říčany u Prahy for a backcasting case study for sustainable hydration. The main findings are that tap water can be better promoted if remunicipalised and available outdoors via drinking fountains. In a blind-tasting experiment, 85% of people couldn’t tell the difference between tap water, bottled spring water, and bottled drinking water. Moreover, 70% of people gave tap water the same or better grade for taste. Awareness about the environmental and social dimension of bottled water is necessary to reach a defined vision for sustainable hydration.

Design education needs to recognise the changing world it services. The way that we live our lives is very different to that of our parents. No doubt the way our children will live their lives will be very different to ours. We exist in an ever changing world. Design education must recognise this constant change and develop long term strategies that enable designers to not only be aware of, but play a major role in this change. Futures thinking – the systematic study of the future – provides design with a structured approach to consider potential futures.

Creating ecologically sustainable ways of life is desirable, necessary, and urgent for the collective future of life on Earth. Although this is acknowledged, aspired to, and increasingly pursued in action, broad-scale sustainability remains unrealised. Western cities offer a strategic place to exemplify and accelerate global sustainability transitions. Such cities are characterised by dense human populations with excessive per capita resource use, but they can also be cornucopias of economic development, progressive politics, and diverse culture and correspondingly act at global hotspots of innovation and change. This exploratory research proposes pragmatic backcasted pathways for furthering such change, constructing future visions of more sustainable ways of life in Western cities, identifying presentday barriers to realising these, and generating practical solutions ‘here and now’ that could contribute strategically to overcoming the barriers, towards a sustainable future. An insight and foresight rich distillation of evidence-based knowledge and practical experience was generated to inform these pathways, through qualitative interviews with 25 esteemed experts specialising in fields of socio-ecology and cities, including planning, design, sociology, psychology, philosophy, art, activism, economics, and government. To analyse this data and conceptualise alternative pathways, ‘ecological habitus’, an emergent socio-ecological theory, was developed and employed as a practical framework for conceptually linking broad-scale socio-ecological issues with everyday practice; analysing the inter-dependent variables (e.g. normative, material, social, and psychological) of social reproduction and change; and assessing their sustainability at different scales (e.g. individual and institutional). Two components were added to the theory: ‘natural capital’ (the ecological/biophysical factors within socio-ecological relationships), and ‘ecological reflexivity’ (people’s responses to natural capital whether intentional-critical, periodic-conscious, or routine-subconscious). These enhance ecological habitus as a versatile tool for socio-ecological and sustainability-transition research.The ultimate research outcomes are three backcasted pathways towards a future of ‘sustainable ecological habitus’, which could begin pragmatically with: collaborative practice among city authorities to develop as ecologically-reflexive sustainability leaders and overcome disciplinary silos; strategic enrichment of cities with accessible, place-based natural capital to enhance human-nature connection; and everyday self-, or socially-directed sustainability micro-interventions among city-dwellers, to incrementally grow mainstream sustainable ecological habitus. These actions combined could accelerate sustainable ecological habitus in Western cities and beyond. The power is ours.

Despite the high profile of climate change in scientific and policy discourse, the Russian government has thus far failed to commit to an emission reduction target based on the latest science. Given Russia is a key supplier of fossil fuels, a major greenhouse gas emitter, and climate impacts on its vast territory likely to have far-reaching consequences, this contextual research shows that the country's current policies fall woefully short of what is required to implement the Paris Agreement. To support Russia in developing informed, internally consistent and scientifically literate energy policies, this paper presents low-carbon emission trajectories commensurate with the 2 °C goal, using stakeholder-informed backcasting. The results illustrate that even if Russia's CO2 emissions peak in 2017, a reduction rate of at least 9% per year between 2020 and 2030 is required to meet a 2°C budget constraint. These sustained rates are in excess of anything achieved globally or, indeed, deemed possible within most studies. Such emission reductions would involve unprecedented material changes to Russia's energy system, including both rapidly cutting energy demand and building extensive low-carbon infrastructures. Nevertheless, failure to transform Russia's existing policies will likely have global repercussions for achieving the Paris Agreement's goals.

Environmental Values is an international peer-reviewed journal that brings together contributions from philosophy, economics, politics, sociology, geography, anthropology, ecology and other disciplines, which relate to the present and future environment of human beings and other species. In doing so we aim to clarify the relationship between practical policy issues and more fundamental underlying principles or assumptions.

"Development of sustainable technologies is increasingly becoming a common business practice. The major challenge faced by product development teams is to link the present to future over a long-term technology development phase in order to break existing path-dependencies and create innovation paths towards sustainability. Another problem is to
identify criteria for new technologies to be sustainable. The previous scenario development studies for envisioning sustainable technologies provide a sound ground to build on while demonstrating some weaknesses needing to be
improved. This paper provides a critical analysis of previous studies in terms of the extent of the coevolutionary approach to innovation, the time frames used and the measure of sustainability adopted. Following this critical analysis, outline of a new scenario methodology is given. This new methodology builds on the multi-level perspective on innovation and incorporates risk into this perspective as a measure of sustainability. The new methodology also proposes a double-flow approach for scenario development, one starting from present and flowing forwards and the other starting from future and flowing backwards in order to be able to identify possible innovation paths over a long period of time."

This paper aims to provide insight into how to cope with complexity and uncertainty in decision making on flood resilience in 13 pilot areas in five countries. This study is part of the Interreg North Sea region project FRAMES. In the pilots different actors work on the exploration and implementation of diversified strategies for flood resilience, based on multiple elements of the disaster management cycle. To gain understanding of the complexity these actors are facing, we discuss more generic insights in climate change adaptation and the complexity of joint action. Since the decisions to be made in the pilot regions depend on the uncertainties about the future, we investigate the supporting role of backcasting and Dynamic Adaptation Policy Pathways in making robust decisions in our present volatile world. Against this backdrop the current flood risk governance arrangements of the participating countries are compared by employing and extending the analysis of the STARFLOOD project (Matczak et al., 2016). These countries differ in their approach towards flood resilience, involving different types of decisions to be made. This variety reflects their historical coevolution with country specific governance settings. In this paper we present our preliminary findings of the transnational learning process within the FRAMES project. In two workshops we have discussed the challenges and complexities considering adaptive strategies for flood resilience. Furthermore we will reflect on the preliminary results of the learning process, flood risk governance arrangements and the presented theoretical background. We will conclude that adaptive planning can support regions in dealing with the complexity and uncertainty in the decision-making and strategy development for flood resilience. Elements of both backcasting and DAPP can complement each other in a co-evolutionary planning approach for flood resilience.

Developing adaptation strategies for deltaic and coastal regions is a major challenge, calling for the development and use of sophisticated futures approaches. The impacts of global climate change will continue to manifest themselves locally, albeit at a varying rate and magnitude. The impacts of floods and droughts on social-ecological systems (SES) impose major challenges. In particular, flood prone deltaic and drought prone coastal regions with high concentrations of population and economic activity in major cities located in floodplains and along the coastline are seriously threatened . Climate change adaptation and future planning have therefore become mandatory for environmental and climate policymakers . As a consequence, futures and scenario studies are increasingly used in long-term climate policy and decision making and related methodology development is increasing.

This paper describes a backcasting study focusing on fulfilment of a national target to decrease energy consumption in residential and commercial buildings by 50% by 2050 compared with the consumption in 1995, and identifying possible measures for achieving it. A method based on a combination of backcasting methodology and focus group methodology was used. Two different scenarios were developed. They were used in discussions with stakeholders in the building sector, to explore and identify measures and actors important for target fulfillment. The main outcomes were ideas for strategies and measures needed to achieve the target. The current potential for target fulfilment was also analysed and discussed. The discussions in the different stakeholder groups were mainly concerned with changes in attitude and behaviour and the need for radical changes in social structures. For example, enhanced communication between actors in the building chain, and the need for relevant feedback in order to illustrate the link between the effort in decreasing energy use and actual outcome. The findings suggest that there is sufficient technical potential to achieve the target by 2050 but that this potential will not be realised to a sufficient extent. Achieving the target would be facilitated by policy that is oriented more towards identifying actors with direct influence to promote change. An analysis of incentives for these actors to act, and how different actors can cooperate for energyefficient solutions should be integrated into the process of suggesting and implementing policy measures. stock, and as most of it will still stand in 2050achieving the target is a major challenge. Energy efficiency in the Swedish building sector improved during the 1970s and early 1980s but stagnated after that . In order to achieve energy-saving targets and accomplish change, new perspectives and methods aimed at both tackling the problems and facilitating the solutions are needed.

Social, natural and cultural systems are changing rapidly, influencing the future of Europe's fresh waters. One of the drivers shaping this future is the implementation of the Water Framework Directive. Participatory scenario development is well-suited to the challenges posed by the WFD to develop a long-term view by involving stakeholders. In this paper we analyse the process and results of a series of stakeholder workshops to develop scenarios at pan-European level. Specifically, we aim at analysing the method and results of combining a backcasting methodology and exploratory scenario development process. Four exploratory scenarios (narrative storylines) were developed, in first instance based on a set of existing European scenarios. Results matched expectations; the process produced stories that are complex, integrated, and rich in detail. During the backcasting exercise, four timelines were constructed, each of which took one exploratory scenario as context. The backcasting process established a strong link with the exploratory scenarios by identifying a large number of obstacles and opportunities in the realisation of those timelines. An analysis across all backcasts yielded a list of 15 robust elements, i.e. elements that are potentially effective in all exploratory scenarios. A stakeholder questionnaire showed that overall there was a widespread satisfaction with both the process and the results. Stakeholders were satisfied with the overall methodology and the exploratory scenarios and somewhat more critical on the backcasting exercise and resulting robust strategies. Above all, we hope to have demonstrated that it is conceptually appealing, methodologically feasible, and practically useful to combine exploratory scenario development and backcasting analysis.

Institutional Investors own a large share of publicly traded companies, controlling a significant amount of the economy"s working capital. These investors currently use little or no sustainability-related information to make their decisions, reinforcing a loop of increasingly unsustainable growth. This paper puts forward a new investment strategy that recognizes true movement towards sustainability and its link with bottom line benefits for investors: Strategic Sustainable Investing (SSI). To achieve this desired future, Institutional Investors must be able to recognize corporations that are strategically leading the transition towards sustainability. An Analysis Tool was developed to help address this need by identifying sectoral Emerging Sustainability Issues (ESI) using a consensus-based scientific definition of sustainability. Once ESIs are identified, companies" strategies regarding each issue are assessed. This Tool was scrutinized by a panel of experts in the financial and sustainable development industries, and was tested on three companies within the Unconventional Oil & Gas Sector in Canada. Results confirmed the usefulness of a tool that can recognize which companies are leading the sustainable development agenda, and identified the need for future research on the financial materiality of sustainability-oriented actions.

Harry Harrison’s 1966 novel, Make Room! Make Room!, is a science fiction based work that proposes a dystopian future that is primarily caused by unchecked population growth. The story is set in New York City in the year 1999 and it takes the reader on a series of journeys that follow a tangled web between the principal characters of Andy Rusch, a police detective, Solomon Kahn, an aged-pragmatist, Shirl Greene, a concubine and interest of Andy Rusch, and Billy Chung, a Taiwanese immigrant who is suspected of murder. Each character is introduced to the reader against a backdrop of cataclysmic failures that have resulted in social collapse and disaster. It is these failures that are the foundation of this interdisciplinary research paper, and the research expects to show how using backcasting that the world could achieve most, if not all, the predictions in Harrison’s novel. In addition to the novel, this research will rely upon the use of the closely-based motion picture, Soylent Green (1973), to make further contrast and comparisons. By using both the novel and the movie, this research can highlight subtle differences and better explain how a theory in Public Administration, Sociology, Economics, and History may better apply to one scenario as opposed to the others.

The introduction of Autonomous Vehicles (AVs) into cities may fundamentally transform the design and use of cities. On one hand, AVs offer the potential to reduce the urban space requirements for roads and parking, creating more space for high-quality, liveable areas. On the other hand, greater motorisation and the availability to perform leisure or work activities while travelling in AVs could increase the number of trips and travel distances, encouraging urban traffic congestion and sprawl. These diverse, and sometimes conflicting, estimates and opinions give rise to considerable uncertainty among urban policy decision-makers, sometimes leading to planning inaction. This paper aims to shed light on the opportunities that AVs offer in delivering attractive, healthy and sustainable urbanisation patterns. This paper employs a backcasting approach to investigate whether and how the potential impacts of AV implementation can support or threaten a range of urban development policy goals. This approach enables conflicts between policy goals to be identified. The findings point to the need for mixed-use development policy, the clustering of urban facilities and services, the restriction of motorized access in cities and the adoption of shared high-quality multimodal transport.

The formulation of policies requires the selection and configuration of effective and acceptable courses of action to reach explicit goals. A one-size-fits-all policy is unlikely to achieve the desired goals; as a result, the identification of a suite of alternative policies, together with clear indications of their trade-offs, is crucial to accommodate the diversity of stakeholders’ preferences. At present, the formulation of transport policies is done manually; this fact, together with the size of the space of possible policies, results in a large part of that space being left unexplored. A six-step framework to explore the space of alternative transport policies in order to achieve environmental targets is proposed. The process starts with a user-defined set of specific policy measures, using them as building blocks in the generation of alternative policy packages, clusters and future images according to the user's preferences and goals.The analysis framework is based on the visioning and backcasting approach used in the VIBAT report [Banister, D., & Hickman, R. (2006a). Visioning and backcasting for UK transport policy (VIBAT) project. Department for Transport's Horizons Research Programme 2004/06. The Bartlett school of planning and Halcrow Group Ltd. Retrieved 1/18/2008 http://www.ucl.ac.uk/∼ucft696/vibat2.html]. The framework is being implemented as a prototype decision support system around a case study: the formulation and analysis of policies required to achieve CO2 emission targets for the transport sector in the UK. Important insights on how to develop the framework have also been elicited from engineering design. The goal is to accelerate the task of policy-making and improve the effectiveness of the resulting policies.The proposed method and computer implementation is fundamentally different from the tools commonly used in the transport sector and is intended to assist (not replace) transport policy makers, and complement (not substitute nor compete with) existing mathematical modelling tools. This research constitutes the first step towards the development of a general family of computer-based systems that support the design of policies to achieve environmental targets—not only for transport, but also for other sectors such as energy and water.

Climate is complex, uncertain, and, over horizons that are relevant for policy decisions, varies little. Using evidence-based (scientific) forecasting principles, we determined that for such a situation a naïve "no change" extrapolation method was the appropriate benchmark. We tested this benchmark against global mean temperatures. To be useful to policy makers, a proposed forecasting method would have to provide forecasts that were substantially more accurate than the benchmark. We calculated benchmark forecasts against the UK Met Office Hadley Centre's annual average thermometer data from 1850 through 2007. The accuracy of forecasts from our naïve model is such that even perfect forecasts would be unlikely to help policy makers. For example, mean absolute errors for 20-and 50-year horizons were 0.18°C and 0.24°C. We nevertheless evaluated the Intergovernmental Panel on Climate Change's 1992 projected warming rate of 0.03°C-per-year. The small sample of errors from ex ante forecasts for 1992 through 2008 was practically indistinguishable from the naïve benchmark errors. To get a larger sample and evidence on longer horizons we backcast successively from 1974 to 1850. Averaged over all horizons, IPCC errors were more than seven-times greater than errors from the benchmark. Relative errors were larger for longer backcast horizons.

The title of this thesis is "Bridging gaps in the scenario world". Before starting, it would be good to reflect a bit on the function of bridges; why would someone want to build a bridge? Bridges are built to connect two parts of the world. In general, they are only build when the bridge will have an added value. These added values are, for instance, that people from both sides can get together and exchange goods, knowledge, and ideas. The same holds for the bridges we have build in the scenario world, we build them because we saw an added value in connecting parts of the scenario world. Furthermore, by connecting different parts in the scenario world these bridges also link to people outside the scenario world. Although it is not 'rocket science' in the sense that rockets are build, it does help to link different worlds; the worlds of social scientist, modellers, stakeholders, and decision makers. The added value of building the bridges described in this thesis is twofold; develop better scenarios and bring different communities in contact with each other. By connecting different parts of the scenario world the quality of the scenario should increase. By bringing different communities together people can learn from each other and discover new solutions to our problems. Hopefully this can help to make our world a little better. Bridging gaps in the scenario world Chapter 1 General Introduction Box 1; Shell scenarios Shell was some of the first companies to use scenarios. Planners at Shell looked for events that might affect the price of oil. During their analysis they found out that the USA was beginning to exhaust its oil reserves while its demand for oil was increasing. At the same time the OPEC was getting stronger. The OPEC resented the Western support of Israel after the 1967 six-day war. It occurred to the planners that the OPEC could increase oil prices to harm the west. The planners developed two scenarios (including storylines and oil price figures). The first one represented the common ideas within Shell; that oil prices would remain relatively stable. It showed that new oil fields were needed, also outside the Arab countries. The other scenario showed an oil price crisis sparked by OPEC. They showed these scenarios to the management, but this did not led to a change in behaviour. The planners then described the scenarios in more detail, including the consequences of a possible oil price shock. They showed the management how an oil crisis would make the oil industry a low growth industry. They told them how OPEC countries could take over Shell's oil fields. By describing the forces and possible influences of those forces they could convince the management that other futures than the expected stable prices could happen and that the effects could be enormous. Then the management started to think about possible actions they should take if an oil crisis would occur. Not too long after, in 1973, an oil crisis occurred and Shell was the only of the major oil companies that, was prepared for such an event. It could therefore respond more quickly and grew from one of the smallest of the seven large oil companies to the second in size and the number one in profitability. (Mietzner and Reger, 2005) Box 2; East Berlin "What would happen if the Wall were taken down?" Erhard Krack, Mayor Of East Berlin, thumped his fingers on the polished wood of his desk. "What you are asking," he replied with agitation, "is a philosophic question. Let us get back to reality." (Vesilind, 1982) Seven years later, the Berlin Wall fell. Bridging gaps in the scenario world 17 Last but not least, scenarios have a bridging function as they can be used to bring different communities together (Xiang and Clarke, 2003). This bridging function between communities is one of the reasons why stakeholders are often involved in the development of scenarios (Wollenberg et al., 2000). 1.1.3. Different types of scenarios Given the variety of definitions and reasons to use scenarios it is not surprising that there is also a wide variety of different scenario types. Several authors have developed typologies to provide an overview of the field (e.g.

The paper reports on a comparative study of three different cases on vision and strategy development for climate change adaptation planning in (i) The South African Breede–Overberg Catchment, (ii) The Mississippi Estuary-New Orleans region and (iii) The Dutch Rhine-Meuse Estuary. The objective of the paper is twofold: to develop a better understanding of such processes and to further develop the Backcasting-Adaptive Management (BCAM) methodology. A framework for case evaluation is developed using six dimensions: (i) inputs and resources, (ii) future vision, (iii) stakeholder engagement, (iv) methodological aspects, (v) pathway development and (vi) impact. Major conclusions based on a cross-case comparison and testing propositions are (i) participatory vision development is a strong tool for climate change adaptation planning in different governance contexts and shows considerable diversity in its application in these contexts; (ii) a single, shared future vision is not a prerequisite for vision and pathway development and endorsement; (iii) broad stakeholder engagement enriches strategy development, but the involvement of marginal groups requires additional efforts and capacity building; (iv) multiple pathways and robust elements are useful but require novel expertise; and (v) more institutional embeddedness and support for participatory processes lead to better implementation of the outcomes of these processes.

Many contemporary societal challenges manifest themselves in the domain of human-environment interactions. There is a growing recognition that responses to these challenges formulated within current disciplinary boundaries, in isolation from their wider contexts, cannot adequately address them. Here, we outline the need for an integrated, transdisciplinary synthesis that allows for a holistic approach, and, above all, a much longer time perspective. We outline both the need for and the fundamental characteristics of what we call "integrated history." This approach promises to yield new understandings of the relationship between the past, present, and possible futures of our integrated human-environment system. We recommend a unique new focus of our historical efforts on the future, rather than the past, concentrated on learning about future possibilities from history. A growing worldwide community of transdisciplinary scholars is forming around building this Integrated History and future of People on Earth (IHOPE). Building integrated models of past human societies and their interactions with their environments yields new insights into those interactions and can help to create a more sustainable and desirable future. The activity has become a major focus within the global change community.

A new set of objectives for sustainable development are now in place, known as the Sustainable Development Goals (SDGs), and countries need to develop concrete policy roadmaps to achieve them. This is particularly challenging in the agricultural sector given the heterogeneity of local conditions, the diffuse nature of its environmental impacts, and the important interactions with various aspects of sustainable developmentfrom education and poverty alleviation, to human health and the environment. And yet it is precisely because of these interactions that vibrant, resilient and sustainable national agricultural sectors are key to the SDGs' success. This paper presents a practical backcasting approach and methodological toolkitdeveloped by the Agricultural Transformation Pathways (ATP) initiative under the auspices of the Sustainable Development Solutions Network (SDSN)for countries to develop policy roadmaps towards 2030 using local tools and expertise that could help transform national agricultural sectors in a way that is consistent with the SDGs. This approach is illustrated using the Uruguayan beef sector as a case study, where productivity and environmental targets were developed in tandem with a wide range of stakeholders in order to maximize productivity, while minimizing a suite of environmental impactsfrom carbon footprint and biodiversity, to nitrogen losses. This marks the beginning of a new approach to achieving the SDGs in the agricultural sector: participatory target setting and pathway development across a number of areas crucial to sustainable developmentall under a harmonized framework provided by the ATP initiative. We hope the methodological approach and results of the Uruguay case study will become a touchstone for future work in this area. & 2016 Published by Elsevier B.V. on key issues of social, economic and environmental concern by 2030. While they are global in scope, the actions these goals require call for concerted efforts at the country-level and below (SDSN, 2014). Consequently, each country needs to build a pathway towards the SDGs: a series of policy measures implemented over time with specific, achievable actions and outcomes at national and sub-national levels. And one sector of the economy that intersects with many issues of sustainable development is agriculture (Canavan et al. 2016).

The sustainability transformation calls for policies that consider the global consequences of local lifestyles. We used stakeholders' visions of sustainable lifestyles across Europe to build 19 scenarios of sufficiency (net reductions) and 17 of green consumption (shift in consumption patterns). We applied Environmentally Extended Multi-Regional Input-Output analysis to model scenarios by assuming widespread adoption of the proposed lifestyles changes. Finally, we estimate the domestic and foreign implications for land, water, carbon and human toxicity potential. We distinguish the options with most potential from those that are seemingly fruitless or present backfire risks. While our method allows for testing a large number scenarios under a consistent framework, further work is needed to add robustness to the scenarios. However, we do find a range of indicative results that have strong potential to contribute to mitigation efforts. Services: We find that a local and sharing service economy has a maximum reduction potential of 18% of the European carbon footprint (CF). Clothing & Appliances: Sharing and extending lifetimes of clothes and devices could diminish CF by approximately 3%. Transport: Reducing motorized transport by remote work and active travel could mitigate between 9-26% of CF. Food: Vegan diets could spare 4% of the land and reduce up to 14% of CF. Bio-economy: Switching to biomaterials and bioenergy tend to reduce carbon and toxic emissions at the risk of increasing water and land use. Housing: Passive housing and decentralized renewable energy reduces carbon emissions up to 5 and 14%, respectively. We characterize the sensitivity of our results by modelling income rebound effects and confirm the importance of deterring expenditure in resource intensive goods.

This chapter explores the strategic implementation of the cradle-to-cradle concept and suggests backcasting using sustainability principles as a systematic way to support decision-makers. The cradle to cradle concept seeks to learn from nature and to design using principles that emphasize the conversion of waste into food, the use of solar energy inputs, and the celebration of diversity. As such, it facilitates organizational transition toward enabling a societal infrastructure by participating in cyclical supply chains – a valuable complement to the green supply chain approach to organizational collaboration for sustainability. The specific contribution of this chapter to the cradle-to-cradle literature focuses on the integration of cradle-to-cradle design within a systems approach that permits analysis from a strategic sustainable development perspective. After usefully comparing cradle-to-cradle design principles with FSSD principles for sustainability, the authors integrate science-based principles with value-based principles as an asset to support backcasting using overarching sustainability constraints drawn from scientific principles for socio-economic sustainability. This framework is one that decision-makers can use flexibly to make mid-course corrections in the march toward a societal infrastructure that supports a targeted system in which all material flows are either part of a biological or a technical metabolism.

Land cover and land use changes can have a wide variety of ecological effects, including significant impacts on soils and water quality. In rural areas, even subtle changes in farming practices can affect landscape features and functions, and consequently the environment. Fine-scale analyses have to be performed to better understand the land cover change processes. At the same time, models of land cover change have to be developed in order to anticipate where changes are more likely to occur next. Such predictive information is essential to propose and implement sustainable and efficient environmental policies. Future landscape studies can provide a framework to forecast how land use and land cover changes is likely to react differently to subtle changes. This paper proposes a four step framework to forecast landscape futures at fine scales by coupling scenarios and landscape modelling approaches. This methodology has been tested on two contrasting agricultural landscapes located in the United States and France, to identify possible landscape changes based on forecasting and backcasting agriculture intensification scenarios. Both examples demonstrate that relatively subtle land cover and land use changes can have a large impact on future landscapes. Results highlight how such subtle changes have to be considered in term of quantity, location, and frequency of land use and land cover to appropriately assess environmental impacts on water pollution (France) and soil erosion (US). The results highlight opportunities for improvements in landscape modelling.

The future implementation of Autonomous Vehicles (AVs) in cities can have significant impacts, both positive and negative, on their sustainability. The objective of this research is to investigate those impacts and evaluate which policies could be most effective in achieving the desired city scenario through a backcasting planning methodology. To this end, a survey among experts was carried out in which they expressed their opinions on the potential consequences of AVs in cities and on the effectiveness of various policy packages focused on achieving a more sustainable mobility and land use planning. The results obtained show that the experts consulted were sceptical about the positive impacts of AVs, arguing that they could induce an increase in car trips and urban sprawl. The policies that could be most effective in mitigating these effects, leading to a city more aligned with the planned objectives would be: to strengthen active (foot, bicycle) and public transport modes, to rest...

In climate change mitigation, backcasting scenarios are often used for exploring options for achieving a single environmental goal, albeit at the expense of other goals. This paper assesses potential conflicts and synergies between multiple environmental policy goals based on four future scenarios on Swedish rural land use, assuming zero GHG emissions in 2060. The assessment shows that goal conflicts are apparent, and policy makers need to make trade-offs between goals. The choice of strategy for dealing with these trade-offs yields conflicts or synergies. The assessment shows that a transition to zero GHG emissions provides opportunities for Sweden to shift to carbon free land-use planning. Overall, there are alternative ways with different underlying assumptions to achieve zero GHG emissions, which will feed discussions on new opportunities to overcome multi-scale and multi-sectoral goal conflicts. Multi-target backcasting scenarios are considered more suited to account for the multi-dimensional aspects of goal conflicts. This requires a comprehensive multi-target backcasting approach, which combines the strengths of multicriteria analysis, nexus approaches and backcasting, for supporting a transition to zero GHG emissions.
