Coastal communities face environmental challenges that put food, energy, and water systems at risk. Although highly interdependent, it is unknown the extent to which coastal resilience research has considered interactions among food–energy–water systems. Twenty peer-reviewed articles were identified that focused on these systems and coastal resilience. Although a nexus approach was not employed universally, these studies most commonly addressed interactions among these systems related to acute hazards. They consistently acknowledged the influence of energy and transportation systems upon the others. As such, planners should incorporate linkages across all three systems during coastal resilience planning especially in relation to acute hazards.

Coastal communities strive for resilience in the face of an ever-growing suite of threats by planning and preparing for numerous uncertain futures. Food, energy, and water systems are highly interconnected and essential to the well-being of coastal communities. However, it is unknown the extent to which coastal resilience research has included food–energy–water nexus considerations. This study used a systematic literature review of peer-reviewed research articles and identified 20 studies that focused on food, energy, and water systems as related to coastal resilience. Results revealed four main findings: (1) the food–energy–water nexus approach was most commonly applied to coastal resilience in the study of US locations and in the context of acute hazards, (2) a direct food–energy–water or other nexus approach was directly employed by only half of the studies, however, all highlighted the relevance of systems interconnections in the context of coastal resilience, (3) the energy system was shown to impact every system to which it was connected, and (4) the transportation system was also shown to impact every system to which it was connected, which suggests that the food–energy–water nexus should be expanded to include transportation systems.

Coastal resilience and food–energy–water nexus literature synthesis finds interconnected systems considerations relevant to resilience.

Scaling sustainable behaviour change means addressing politics, power and social justice to tackle the uneven distribution of responsibility and agency for climate action, within and between societies. This requires a holistic understanding of behaviour that bridges the ‘individual’ and ‘systemic’, and acknowledges the need for absolute emissions reductions, especially by high-consuming groups, and in key ‘hotspots’ of polluting activity, namely, travel, diet and housing. It counters the dominant focus on individuals and households, in favour of a differentiated, but collective approach, driven by bold climate governance and social mobilisation to reorient institutions and behaviour towards just transitions, sufficiency and wellbeing.

Sustainable behaviour change has been rising up the climate policy agenda as it becomes increasingly clear that far-reaching changes in lifestyles will be required, alongside shifts in policy, service provision and technological innovation, if we are to avoid dangerous levels of global heating. In this paper, we review different approaches to behaviour change from economics, psychology, sociology and political economy, to explore the neglected question of scalability, and identify critical points of leverage that challenge the dominant emphasis on individual responsibility. Although politically contentious and challenging to implement, in order to achieve the ambitious target of keeping warming below 1.5 degrees, we propose urgent structural interventions are necessary at all points within an ecosystem of transformation, and highlight five key spheres for action: a ‘strong’ sustainability pathway; pursuing just transitions (via changes to work, income and infrastructure); rebalancing political institutions to expand spaces for citizens vis-à-vis elite incumbents; focusing on high polluting actors and activities; and supporting social mobilisation. We call for a move away from linear and ‘shallow’ understandings of behaviour change, dominated by traditional behavioural and mainstreaming approaches, towards a ‘deep’, contextualised and dynamic view of scaling as a transformative process of multiple feedbacks and learning loops between individuals and systems, engaged in a mutually reinforcing ‘spiral of sustainability’.

Scaling behaviour change means addressing power and politics: challenging polluter elites and providing affordable and sustainable services for all.

Nations across the world are concerned with environmental issues like forest loss. The majority of nations acknowledge the importance of reducing forest loss, and make commitments to do so. However, researchers often find that despite these commitments, and the work of non-governmental organizations, in many nations, forest loss is not declining. This research argues that institutional capacity, specifically a nations domestic autonomy may help explain the ineffectiveness of environmental international non-governmental organizations (EINGOs) at reducing forest loss. Specifically, I argue that nations with stronger domestic autonomy, measured as the extent to which a nation is free of the direct control of external political actors, improves the effectiveness of EINGOs at reaching their goals of reducing forest loss due to an autonomous state's relative strength and ability to integrate their version of environmentalism or reinterpret existing norms of environmentalism into EINGO ideologies and activities.

Previous research finds that environmental international non-governmental organizations (EINGOs) tend to have differential impacts on environmental factors cross-nationally, such as forest loss. More recent work argues that decoupling between stated environmental norms and actual environmental outcomes may be the result of a lack of institutional capacity. Using ordinary least squares regression for 91 low- and middle-income nations from 2001 to 2014, I find that EINGOs reduce forest loss more in nations with higher rather than lower levels of domestic autonomy. However, I find that EINGOs and domestic autonomy on their own do not significantly predict forest loss.

This research argues that a nations domestic autonomy may help explain the ineffectiveness EINGOs at reducing forest loss.

Tropical deforestation continues apace despite a proliferation of commitments made by companies and governments to control it. Halting and reversing deforestation requires multiple, complementary interventions by state and non-state actors at different scales. We argue that the order in which these instruments and actors are introduced into the policy mix matters. Sequences of interventions from case studies in Latin America show that government commitment is a critical first step, implemented through command-and-control measures and then incentives. Combined with REDD+, they create an enabling environment for supply chain initiatives. A more coordinated and deliberate polycentric governance is needed to achieve zero-deforestation.

Avoided deforestation provides a natural climate solution for reducing emissions while generating co-benefits for people and nature. However, unleashing this potential requires improved governance. Diverse coalitions of actors are designing interventions to protect forests, each with different motivations and specialization of strategies. We introduce a policy sequencing framework to advance our understanding of how to improve polycentric zero-deforestation governance. Focusing on commodity production in Costa Rica, Brazil, and Colombia, we reconstructed the policy mix of zero-deforestation interventions across three domains – domestic public policies, REDD+, and supply chain initiatives. We classified interventions according to their instrument mechanism – disincentives, incentives, enabling measures – and when they were introduced into the policy mix. We found a sequence of interventions that reflects stages of forest cover dynamics, but also depends on local political will and institutional capacity. Government command-and-control measures are needed early in the policy sequence to slow deforestation, with incentives added to increase legal compliance. REDD+ helps governments build an enabling environment that supports supply chain initiatives seeking to increase forest cover at later stages of the sequence. Policy sequencing and policyscape concepts advance the design of more deliberate polycentric forest governance that enhances actor coordination and instrument synergies in the policy mix.

How do we stop deforestation? The policy options are well-known, but the order in which they are introduced matters.

We summarize some of the past year's most important findings within climate change-related research. New research has improved our understanding about the remaining options to achieve the Paris Agreement goals, through overcoming political barriers to carbon pricing, taking into account non-CO2 factors, a well-designed implementation of demand-side and nature-based solutions, resilience building of ecosystems and the recognition that climate change mitigation costs can be justified by benefits to the health of humans and nature alone. We consider new insights about what to expect if we fail to include a new dimension of fire extremes and the prospect of cascading climate tipping elements.

A synthesis is made of 10 topics within climate research, where there have been significant advances since January 2020. The insights are based on input from an international open call with broad disciplinary scope. Findings include: (1) the options to still keep global warming below 1.5 °C; (2) the impact of non-CO2 factors in global warming; (3) a new dimension of fire extremes forced by climate change; (4) the increasing pressure on interconnected climate tipping elements; (5) the dimensions of climate justice; (6) political challenges impeding the effectiveness of carbon pricing; (7) demand-side solutions as vehicles of climate mitigation; (8) the potentials and caveats of nature-based solutions; (9) how building resilience of marine ecosystems is possible; and (10) that the costs of climate change mitigation policies can be more than justified by the benefits to the health of humans and nature.

Negative emissions technologies (NETs) have received increasing interest in recent years as a potential part of a portfolio of measures to address anthropogenic climate change, in particular following the 2015 UN Framework Convention on Climate Change Paris Agreement and the 2018 Intergovernmental Panel on Climate Change Special Report ‘Global Warming of 1.5 °C’. This increasing significance for global climate policy is faced with a multitude of open questions regarding, among others, the geopolitical implications of large-scale use of NETs. This paper outlines what we can learn for the possible geopolitical futures of NETs from existing international ‘green’ approaches.

We contribute to assessing political implications of NET scenarios, addressing the following question: What are potential geopolitical challenges, conflicts, and consequences of a large-scale deployment of three NETs, namely afforestation, bio-energy with carbon capture and storage (BECCS), and direct air capture and carbon storage (DACCS)? We turn to the two cases of renewable energies and reducing emissions from deforestation and forest degradation for answers. We find that, first, not only afforestation, but also BECCS and even DACCS would have a geopolitical impact due to their requirements of territory – in the latter two cases, for instance, due to requirements for appropriate carbon storage space. Second, the material requirements of various NETs might also impact geopolitical constellations and induce conflict, providing certain countries and regions of the world with new leverage in the case of large-scale deployment, for instance those which can provide raw materials for fertilizer (for afforestation and BECCS) or energy generation (for DACCS). Third, discursive construction of space and identity might lead to very interesting new patterns of contestation, for instance if specific nation-states can successfully construct an identity of front-running climate protectors and use this to put pressure on other states.

What might be geopolitical implications of using NETs on a large scale to counteract anthropogenic climate change?

The exponential growth of humanity's resource consumption over the last half-century has led to ecological decline while people's basic needs have not been universally satisfied. The ‘doughnut economy’ and sustainable consumption corridor concepts have gained global attention, providing frameworks in which the maximum allowable environmental impacts and the minimum social levels acceptable to lead a good life establish a guiding pathway to meet human needs whilst remaining within the Earth's carrying capacity. We apply this thinking to the urban mobility sector in this article in an attempt to formulate a ‘safe and just space’ for urban mobility.

The theoretical and broad application of the ‘doughnut economy’ and sustainable consumption corridor concepts are lacking in implementation due to a limited understanding of sectoral thresholds. This study highlights the weakness of sustainable urban mobility indicator studies which often lack connections to ecological ceilings and social foundations and, thus, lack the ability to show if a mobility system is intergenerationally sustainable or not. Therefore, this study aims to bridge this knowledge gap and develop a mobility sector-focused sustainable consumption corridor. It does so by using a collection of concepts and associated indicators ranging from sustainable urban mobility, sustainable consumption corridors, ecological thresholds, needs theory and mobility social impacts to mobility poverty. The output of this study is an initial design of a mobility-focused sustainable consumption corridor with suggested themes and indicators to measure the relative performance of a region in relation to the material dimensions of the corridor accompanied by a discussion surrounding spatial, temporal and sectoral corridor-defining thresholds. This work provides a novel first step in the direction of sector-based sustainable consumption corridors which can aid in providing a transformational alternative to the status quo through the implementation of safe and just sectors.

This article applies the ‘doughnut economy’ and sustainable consumption corridors to the urban mobility sector. It provides a framework for evaluating urban mobility systems in terms of their ecological impacts (the ‘ecological ceiling’) and providing for human needs (the ‘social floor’), and for defining a ‘safe and just space for urban mobility’.

Our time seems to be trapped in a paradox. On the one hand, the capacity to master information has tremendously increased, but on the other hand the capacity to use the knowledge humanity produces seems at stake. There is a gap between our capacity to know and our capacity to act. We attempt to better understand that situation by considering the evolution of knowledge processing along human history, in particular the relation between the development of information technologies and the complexity of societies, the balance between the known and the unknown, and the current emergence of autonomous machines allowing intelligent processes.

Information-processing capacities developed historically in conjunction with the complexity of human societies. Positive feedback loops contributed to the co-evolution of knowledge, social organization, environmental transformation, and information technologies. Very powerful loops now drive the rapid emergence of global digital platforms, disrupting legacy organizations and economic equilibria. The simultaneous emergence of the awareness of the sustainability conundrum and the digital revolution is striking. Both are extremely disruptive and contribute to a surge in complexity, but how do they relate to each other? Paradoxically, as the capacity to master information increases, the capacity to use the knowledge humanity produces seems to lag. The objective of this paper is to analyze the current divergence between knowledge and action, from the angle of the co-evolution of information processing and societal transformation. We show how the interplay between perception and action, between the known and the unknown, between information processing and ontological uncertainty, has evolved toward a sense of control, a hubris, which abolishes the unknown and hinders action. A possible outcome of this interplay might lead to a society controlled to stay in its safe operating space, involving a strong delegation of information processing to autonomous machines, as well as extensive forms of biopolitics.

The sustainability conundrum and the digital revolution are entangled phenomena leading to complexity and disruption.

Transformation of the world towards sustainability in line with the 2030 Agenda requires progress on multiple dimensions of human well-being. We track development of relevant indicators for Sustainable Development Goals (SDGs) 1–7 against gross domestic product (GDP) per person in seven world regions and the world as a whole. Across the regions, we find uniform development patterns where SDGs 1–7 – and therefore main human needs – are achieved at around US$15,000 measured in 2011 US$ purchasing power parity (PPP).

How does GDP per person relate to the achievement of well-being as targeted by the 2030 Agenda? The 2030 Agenda includes global ambitions to meet human needs and aspirations. However, these need to be met within planetary boundaries. In nascent world-earth modelling, human well-being as well as global environmental impacts are linked through economic production, which is tracked by GDP. We examined historic developments on 5-year intervals, 1980–2015, between average income and the advancement on indicators of SDGs 1–7. This was done for both seven world regions and the world as a whole. We find uniform patterns of saturation for all regions above an income threshold somewhere around US$15,000 measured in 2011 US$ PPP. At this level, main human needs and capabilities are met. The level is also consistent with studies of life satisfaction and the Easterlin paradox. We observe stark differences with respect to scale: the patterns of the world as an aggregated whole develop differently from all its seven regions, with implications for world-earth model construction – and sustainability transformations.

Reaching human well-being #SDGs takes GDP levels of $15k. This may help shape transformation to a world that respects #PlanetaryBoundaries.
