The current COVID-19 pandemic has affected societies across the world while its economic impact has cut deeper than any recession since the Second World War. Climate change is potentially an even more disruptive and complex global challenge. Climate change could cause social and economic damage far larger than that caused by COVID-19. The current p...

Understanding the psychology of human-wildlife interactions has grown beyond cognitive frameworks to include appreciation of roles played by emotion in human responses to wildlife. From its beginnings as an essentially cognitively framed proposition, mental modeling has been shown readily applicable to representing and interpreting stakeholder pers...

This paper offers an approach to long-term planning for an industrial sector that is sensitive to climate change, the state of adjacent natural environments and the associated socioeconomic developments. The paper combines exploratory and target-seeking scenarios to understand the future challenges of nature-based blue tourism under alternative glo...

Eurasian beaver, Castor fiber has been restored to England’s natural fauna following a trial reintroduction in the country’s southwestern region. Beavers characteristically generate profound and frequently beneficial shifts to river dynamics, nutrient cycling, biodiversity, and human cultural experience, but can also be associated with unwanted hum...

The goal of limiting global warming to well below 2°C as set out in the Paris Agreement calls for a strategic assessment of societal pathways and policy strategies. Besides policy makers, new powerful actors from the private sector, including finance, have stepped up to engage in forward-looking assessments of a Paris-compliant and climate-resilien...

Participatory modelling (PM) processes involve stakeholders in developing a simplified representation of reality based on stakeholders' knowledge, perceptions, values and assumptions about a system in which they live and/or work. There has been an increase in the need for structured methods for the implementation of PM processes, to elicit knowledg...

Climate change adaptation requires understanding of complex social ecological systems (SESs). One source of uncertainty in complex SESs is ambiguity, defined as the range and variety of existing perceptions in and of an SES, which are considered equally valid, resulting in a lack of a unique or single system understanding. Current modelling practic...

There is a growing interest in different forms of participatory modeling that bring science and lay knowledge into the same space. This recognizes that, traditionally, the environmental science community has mostly seen stakeholder engagement as a 'follow on' activity to be undertaken once the key scientific research has been completed. By excludin...

Chapter 16 focuses on expert models, which are computer-based models that can mimic (or outperform) the decisions of a human expert. Expert models belong to the field of artificial intelligence and essentially use inference techniques to deduce novel information of the system under study. The chapter discusses Bayesian networks and fuzzy cognitive...

Long-term global scenarios have underpinned research and assessment of global environmental change for four decades. Over the past ten years, the climate change research community has developed a scenario framework combining alternative futures of climate and society to facilitate integrated research and consistent assessment to inform policy. Here...

Scenarios describe plausible and internally consistent views of the future. They can be used by scientists, policymakers and entrepreneurs to explore the challenges of global environmental change given an appropriate level of spatial and sectoral detail and systematic development. We followed a nine-step protocol to extend and enrich a set of globa...

With growing awareness of the adverse impacts of anthropogenic climate change, it is essential to understand whether and how societal transformation can be achieved. Future society’s ability to transform depends on how human agency can develop within evolving socioeconomic contexts. Scenarios, therefore, provide different enabling conditions and ch...

With this letter, we respond to the commentary by Kamp et al. on our paper (Nunez et al. in Reg Environ Chang 20:39, 2020) that reports on potential biodiversity change in Central Asian grasslands using climate and land-use change scenarios. In their commentary, Kamp et al. criticize data and methods employed and discuss several shortfalls of our a...

Central Asian grasslands are extensively used for pastoral livestock grazing. This traditional land use is nowadays characterized by intensifying grasslands into more productive pastures. This change affects biodiversity and diminishes grasslands’ ecological role. Biodiversity impacts are probably also exacerbated by climate change. These changes i...

The complex interactions of drivers represented in scenarios and climate change impacts across scales have led to the development of multiscale scenarios. Since the recent development of global shared socioeconomic pathways (SSPs), which have started being downscaled to lower scales, the potential of scenarios to be relevant for decision making and...

Moving towards a more sustainable future requires concerted actions, particularly in the context of global climate change. Integrated assessments of agricultural systems (IAAS) are considered valuable tools to provide sound information for policy and decision-making. IAAS use storylines to define socio-economic and environmental framework assumptio...

Scenarios are a useful tool to explore possible futures of social-ecological systems. The number of scenarios has increased dramatically over recent decades, with a large diversity in temporal and spatial scales, purposes, themes, development methods, and content. Scenario archetypes generically describe future developments and can be useful in mea...

With a range of potential pathways to a sustainable future compatible with the Paris Agreement 1.5 °C target, scenario analysis has emerged as a key tool in studies of climate change mitigation and adaptation. A wide range of alternative scenarios have been created, and core amongst these are five socioeconomic scenarios (Shared Socioeconomic Pathw...

Uncertainties in our understanding of current and future climate change projections, impacts and vulnerabilities are structured by scientists using scenarios, which are generally in qualitative (narrative) and quantitative (numerical) forms. Although conceptually strong, qualitative and quantitative scenarios have limited complementarity due to the...

Scenarios have been recognised as a useful tool for planning, which have resulted in a strong increase in the number of (multi-scale) scenarios in climate change research. This paper addresses the need for methodological progress and testing of conceptual considerations, by extending the global shared socio-economic pathways (SSPs). We present a se...

The complex challenges arising from climate change that exceeds the +2 °C target (termed ‘high-end climate change’) in Europe require new integrative responses to support transformations to a more sustainable future. We present a novel methodology that combines transition management and high-end climate and socioeconomic change scenarios to identif...

Climate change and land-use change are two major drivers of vegetation change causing habitat and biodiversity loss and posing a threat to the sustained provisioning of ecosystem goods and services. Following-up on the Millennium Ecosystem Assessment, the Sustainable Development Goals have been a fresh stimulus to the current interest in ecosystem...

The Mediterranean region is anticipated to be (or, already is) one of the hot spots for climate change, where freshwater ecosystems are under threat from the effects of multiple stressors. Climate change is impacting natural resources and on the functioning of Ecosystem Services. The challenges about modelling climate change impact on water cycle i...

The objective of this study is to provide spatially distributed water use maps at a high spatial and thematic resolution as detailed input data for further modelling purposes. The maps were derived on the basis of official water statistics and land use maps to represent the current conditions in four European river basins affected by water scarcity...

Human use of land increasingly alters the structure and the functioning of the environment. To ex-ante understand and anticipate these changes there is an increased need for readily available and operational land use change models. One of these models is CLUE, which has been used in many studies all over the world. These studies brought forward ope...

Successfully meeting the mitigation and adaptation targets of the Paris Climate Agreement (PA) will depend on strengthening the ties between forests and agriculture. Climate-smart land use can be achieved by integrating climate-smart agriculture (CSA) and REDD+. The focus on agriculture for food security within a changing climate, and on forests fo...

Understanding complex processes of landscape change is crucial to guide the development of future landscapes and land resources. Through Fuzzy Cognitive Mapping, we studied the processes of landscape change of six different environmental zones in Europe. Results show that landscapes are complex systems, with many interactions. Except for one, all r...

The challenge of meeting the UNFCCC CoP21 goal of keeping global warming ‘well below 2 °C and to pursue efforts towards 1.5 °C’ (‘the 2–1.5 °C target’) calls for research efforts to better understand the opportunities and constraints for fundamental transformations in global systems dynamics which currently drive the unsustainable and inequitable u...

Either meeting the UNFCCC Paris agreement to limit global average warming below the 2–1.5 °C threshold, or going beyond it entails huge challenges in terms of institutional innovation and transformation. This research describes a participatory integrated assessment process aimed at exploring the options, opportunities, necessary capacities and impl...

This chapter presents the lessons and challenges in land change modeling that emerged from years of reflection and numerous panel discussions at scientific conferences concerning a collaborative cross-case comparison in which the authors have participated. We summarize the lessons as nine challenges grouped under three themes: mapping, modeling, an...

Climate change is expected to reduce water availability in the Mediterranean region and water management needs to adapt to future conditions. The aims of this study were (1) to develop a participatory approach for identifying and evaluating management options for river basin climate adaptation and (2) to apply and evaluate the approach in four case...

Stakeholder involvement in modeling studies is increasing. Fuzzy Cognitive Maps (FCMs) are emerging as a promising tool to provide a common base for stakeholders and modelers. FCMs developed by stakeholders from three local Mediterranean case studies are used to construct a stakeholder based FCM. This is done via a workshop in which the locally dev...

Literature critiques current predictive scenario approaches applied in the forest sector. Backcasting -a means to create normative scenarios- seems promising, but sparsely used. Combining backcasting with exploratory scenarios (combined scenario approach) seems appropriate to address these critiques. We performed such an exercise with the participa...

This policy booklet, High-End Climate Change in Europe, is based on “work in progress” by researchers from the IMPRESSIONS, HELIX and RISES-AM projects.

Water and water-related services are major components of the human wellbeing, and as such are major factors of socio-economic development; yet freshwater systems are under threat by a variety of stressors (organic and inorganic pollution, geomorphological alterations, land cover change, water abstraction, invasive species and pathogens). Water scar...

In the land use and land cover (LULC) literature, narrative scenarios are qualitative descriptions of plausible futures associated with a combination of socio-economic, policy, technological, and climate changes. LULC models are then often used to translate these narrative descriptions into quantitative characterizations of possible future societal...

Climate change and land-use change are two major drivers of biome shifts causing habitat and biodiversity loss. What is missing is a continental-scale future projection of the estimated relative impacts of both drivers on biome shifts over the course of this century. Here, we provide such a projection for the biodiverse region of Latin America unde...

What does the future hold for the world’s ecosystems and benefits that people obtain from them? While the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES) has identified the development of scenarios as a key to helping decision makers identify potential impacts of different policy options, it currently lacks a long-term sce...

An extensive body of literature in the field of agro-ecology claims to show the positive effects that maintenance of ecosystem services can have on sustainably meeting future food demand, by making farms more productive and resilient, and contributing to better nutrition and livelihoods of farmers. In Africa alone, some research has estimated a two...

Site-specific strategies adopted with the aim of i...

We used Fuzzy Cognitive Mapping (FCM) to assess the process of landscape change. A Cognitive Map is a cognitive interpretation of the system and graphical representation, where components are represented as boxes and relationships as arrows. The state of a system component is not exact but rather represented in a number of classes (‘strong’ or ‘wea...

Deforestation is a widely recognized problem in the Brazilian Amazon. Small farmers play a key role in this process in that they earn their livelihood by ranching and farming. Many studies have addressed the link between deforestation and livelihood strategies adopted by small farmers. Most have focused on advanced monitoring systems, simulation mo...

Long-term scenarios play an important role in research on global environmental change. The climate change research community is developing new scenarios integrating future changes in climate and society to investigate climate impacts as well as options for mitigation and adaptation. One component of these new scenarios is a set of alternative futur...

We set out to map the soil organic carbon (SOC) content, as an indicator of soil fertility, at the village scale, and to relate the SOC content to farm scale management and landscape scale characteristics. Topsoil samples were taken at 100 randomly locations in the Murewa smallholder farming area in Zimbabwe and analysed for organic carbon. Using d...
