India needs to balance carbon mitigation with its developmental priorities. The Indian district acts as an important administrative site where national- and state-level developmental and environmental policies are translated into ground-level implementation. In this work, we provide a replicable approach to analyze the evolution of district-level carbon emissions in near real-time. Our work shows that emissions are concentrated in a small number of districts, with this concentration increasing over time. We also find significant inter-district variation in the growth of emissions. We demonstrate the utility of high-resolution emissions data through three examples.

With India accounting for a growing share of world emissions, the country's carbon emissions trajectory is important from a global mitigation perspective. At the same time, India is simultaneously attempting to achieve both environmental and developmental goals. The district acts as an administrative site that is important for India's future trajectory, as developmental and environmental policies at the national and state levels get translated to actual implementation at the district level. In this work, we study the evolution of carbon emissions at the district level in India. We rely on the GRACED dataset that provides daily emissions information for various sectors at a spatial resolution of 0.1°. We find that 7% of districts account for ∼50% of total emissions, while the bottom 50% contribute less than 9%. This spatial concentration is intensifying over time. We also document variations in the contribution of different sectors to total emissions over the year. We demonstrate the utility of high-resolution emissions data through three examples. Our approach can aid researchers and policymakers in developing targeted interventions as it is easily replicable, goes beyond existing work in its spatial and temporal resolution, and can be adapted to study district emissions in near-real time.

We provide a replicable approach to assess the evolution of India's district-level carbon emissions in near-real-time.

How can wellbeing for all be improved while reducing risks of destabilising the biosphere? This ambition underlies the 2030 Agenda but analysing whether it is possible in the long-term requires linking global socioeconomic developments with life-supporting Earth systems and incorporating feedbacks between them. The Earth4All initiative explores integrated developments of human wellbeing and environmental pressures up to 2100 based on expert elicitation and an integrated global systems model. The relatively simple Earth4All model focuses on quantifying and capturing some high-level feedback between socioeconomic and environmental domains. It analyses economic transformations to increase wellbeing worldwide and increase social cohesion to create conditions that are more likely to reduce pressures on planetary boundaries. The model includes two key novelties: a social tension index and a wellbeing index, to track societal progress this century. The scenarios suggest that today's dominant economic policies are likely to lead to rising social tensions, worsening environmental pressures, and declining wellbeing. In the coming decades, unchecked rising social tensions, we hypothesise, will make it more difficult to build a large consensus around long-term industrial policy and behavioural changes needed to respect planetary boundaries. We propose five extraordinary turnarounds around poverty, inequality, empowerment, energy and food that in the model world can shift the economy off the current trajectory, improve human wellbeing at a global scale, reduce social tensions and ease environmental pressures. The model, the five (exogenous) turnarounds and the resulting two scenarios can be used as science-policy boundary objects in discussions on future trajectories.

Our world is facing a convergence of environmental, health, security, and social crises. These issues demand urgent, systemic solutions now that address not only environmental but also social dimensions. Weak political responses have stalled progress on the Sustainable Development Goals and the Paris Agreement. We have developed scenarios that explore interconnections between possible climate futures, rising living costs, and increasing inequalities that fuel populism and undermine democracy to the year 2100. We propose five turnaround solutions – energy, food and land systems, inequality, poverty, and gender equality – that if enacted are likely to provide wellbeing for a majority of people plus greater social cohesion. This will support long-term industrial policies and behavioural change to reduce emissions and protect the biosphere toward a long-term goal of living on a relatively stable planet.

Our dominant economic model is destabilising societies and the planet. Earth4All found 5 turnarounds for real system change.

Avocados are a widely consumed fruit and are part of many Latin American cuisines and plant-based diets globally. However, producing avocados is water-intensive, and plantations can cause soil erosion and water stress. In Chile, avocados are produced in semiarid zones and require irrigation. They are widely consumed locally but are increasingly exported to meet growing global demand. This causes significant local conflicts over water, especially because of the system of private water rights in Chile. There are many gaps in understanding the complex and interconnected system of avocado production and international markets, especially its impacts on local communities and biodiversity.

The popularity of avocados has increased globally in alternative diets, alongside its integral role in Latin American cuisine. In Chile, avocados are grown extensively and intensively in orchards in the dry and Mediterranean climate of Central Chile. Avocado is a water-demanding crop and the severe water crisis in Chile has called attention to the conflicts caused by its water use. As most of the pressure to produce avocado comes from international demand but results in impacts on native ecosystems and local communities, avocado production in Chile is an example of a telecoupled system. Here, we characterize avocado production as a telecoupled social–ecological system in order to identify gaps in knowledge, based on a review of key studies. Research priorities include how to improve water-use efficiency, especially in the context of climate change; the impacts on biodiversity; and the socioeconomic dynamics between local communities, trade, and governance. The analysis is constrained by limited access to data and few interdisciplinary studies on the matter. To reduce the impacts of avocado production and increase its sustainability, there is an urgent need to amplify the interdisciplinary research that emphasizes the interconnections between the social and ecological components in avocado production in Chile.

Global avocado demand fuels local conflicts in Chile due to water stress and social–ecological pressures on communities.

In response to the concerns of a growing number of crises, we trace the temporal trends, distribution, and co-occurrences of shocks – sudden events with noticeable impacts – on 175 countries from 1970 to 2019. Our analysis shows that shocks have not evolved uniformly over time and space: after becoming more co-occurring between 1970 and 2000, they then showed a regionally dependent shift in patterns. Our results highlight that regional differentiation is not incidental but constitutive of polycrisis dynamics, and that any effort to theorize, anticipate, or navigate polycrisis must account for this spatial heterogeneity.

Polycrisis has emerged as a new property of the Anthropocene. Defined as the convergence of crises across multiple systems, polycrisis calls for a paradigm shift in how crises are perceived and managed. Characterizing polycrisis dynamics is the first step in that direction but is made difficult by the complex and non-linear mechanisms at play. To overcome this challenge, we adopt a social-ecological systems approach to decompose polycrisis dynamics into two interrelated processes: shocks – sudden events with noticeable impacts, and creeping changes – slow processes that have a potential significant impact on society or the biosphere. We then develop and analyse a harmonized database capturing the occurrence of six categories of shocks (climatic, geophysical, ecological, economic, technological, and conflict-related) across 175 countries between 1970 and 2019. Our analysis reveals a significant rise in shock co-occurrences until 2000, particularly at the intersection of conflict, climate, and technological disruptions. After 2000, co-occurrence began plateauing or declining in all regions, yet at different levels. Our findings highlight the importance of a regionalized and typologically nuanced approach to understanding polycrisis. Our work also paves the way to an integration of polycrisis theory and multi-hazard methodologies for developing a more effective and crisis management ecosystem.

Dynamics of the polycrisis reveal regional differences, with a possible shift in the interaction of shocks from 2000.

The need for critical minerals for various technologies for commercial and defense use has led to a range of national policy interventions. However, many of these new laws to encourage mining, or protect local industries have not considered as scientific data on mineral reserves or the economic viability of setting specific targets. The EU’s Critical Raw Materials Act is a pivotal case in point that illustrates this challenge. We present a review of the range of laws and policies that have been set forth worldwide.

Growing international conflict between countries that have large mineral production and processing capacity and those which are in demand of critical raw materials for new technologies has led to a proliferation of policies that promote resource nationalism or ‘friend-shoring’. We analyzed over 400 critical raw material policies to date that have been documented by the International Energy Agency's policy tracking tool and present the findings of the six most active jurisdictions. The EU's Critical Raw Materials Act which came into force in May 2024 stands out as the most significant legislative step taken thus far but needs better interface with environmental and social data on impacts and benefits. By analyzing the challenges faced by lithium mining projects across a range of technologies and geographic locations in Europe, we suggest the use of data generated from life cycle analyses, economic geological calculations, and ecosystem service valuation in improving the implementation of such policies and also mitigate social conflicts.

There are now more than 400 critical raw material policies worldwide, but they need to be predicated in economic and geological data to be effective.

Humans are currently grappling with the challenge of nitrogen (N) management, which involves a multidimensional trade-off between the benefits of N use and the consequences of N pollution. For this study, a deliberative experiment was conducted in which five N scientists, divided into two groups, envisioned the future of NH3 use in the 2050s, adopting the perspective of an imaginary future generation. Through this experience, the study encourages scientists to adopt the proposed framework and embrace freedom to explore desirable future visions, in addition to their usual task of empirically establishing universal disciplinary knowledge.

Humans are currently grappling with the challenge of nitrogen (N) management, which involves a multidimensional trade-off between the benefits of N use and the consequences of N pollution. The urgency to address this issue is already pronounced and may escalate further due to the emergence of ammonia (NH3) as a carbon-free energy resource. For this study, a deliberative experiment was conducted in which five N scientists, divided into two groups, envisioned the future of NH3 use in the 2050s, adopting the perspective of an imaginary future generation. The study revealed that some scientists encountered what is referred to in this study as the ‘positivist gap’, which involves difficulties forming narratives about unpredictable futures that rely on arbitrary assumptions. From this experience, this study develops and illustrates a framework that incorporates (i) Future Design workshops and (ii) abstracting operation for the workshop outputs. Although conducted in Japan, this study aims to inspire similar research in other countries.

A visioning experiment showed how scientists handle nitrogen trade-offs, imagining NH₃’s roles in a complex 2050 world.

As cities like Beijing expand rapidly, green and blue spaces (GBS)—essential for ecosystem services (ESs) such as clean air, flood control, and recreation—are increasingly threatened. This 20-year study examines how urban expansion and policy interventions have shaped Beijing’s GBS. While green initiatives have increased natural areas, unchecked urban sprawl has fragmented these spaces, reducing their environmental benefits. Satellite data and urban planning analyses underscore a key lesson: maintaining well-connected natural zones is critical for urban resilience. These findings are broadly applicable for rapidly growing cities globally, urging urban planners to integrate ecological conservation with development, and to safeguard healthy environments and vibrant communities.

This study quantifies the spatiotemporal dynamics of urban GBS in Beijing, evaluating their essential role in delivering ESs and strengthening urban resilience. Although China has achieved substantial progress in urban greening, the ecological impacts of rapid urbanization on GBS configuration and connectivity have not been comprehensively quantified. Using an integrated analytical framework combining principal component analysis and multiple linear regression, we reveal how urban development strategies have shaped GBS dynamics over two decades. A spatially explicit analysis, utilizing geographically weighted regression, further elucidates the heterogeneous relationships among the normalized difference vegetation index, human footprint index, and ESs delivery capacity. Notably, socioeconomic incentives and green infrastructure governance—especially objective indicators such as forest, garden, and greenspace area—have effectively driven GBS expansion. However, urban expansion has led to pronounced fragmentation of peri-urban GBS, suggesting potential degradation of their ecosystem service support functions. These findings emphasize the need for adaptive GBS management strategies that balance ecological conservation with sustainable urban growth in rapidly developing cities.

Urban growth fragments green and blue spaces, reducing vital ecosystem services. Balancing conservation with development is essential for sustainable cities.

Several transnational corporations, investors, international organizations, and philanthropies have formed coalitions to respond to global social and environmental challenges. Do these coalitions, consisting of large-scale actors, have the capacity to contribute to the sustainability transformations that are needed, or do they perpetuate the same systemic dynamics that created the problems in the first place? We investigate this question by comparing publicly available information from five coalitions working on financial and food systems sustainability.

This paper examines whether large-scale actor coalitions (LSACs) may contribute to transformations toward equitable and sustainable futures. We use a ‘rapid assessment’ 20-variable framework to collect and analyze empirical data from five food and finance coalitions to identify their roles and capacities for transformative change. Our results indicate that LSACs implement distinct strategies to reach their goals. More specifically, due to their diverse set-ups, LSACs have the ability to raise awareness of sustainability issues, utilize ties to push forward agendas, engage in institutional policy-shaping processes, experiment with solutions, and showcase promising niche initiatives. We identify ways that LSACs’ actions can enable efforts of other change-makers who aim to change the food and finance systems and contribute to systems with high and diverse capacities for transformative change. We also discuss why the roles and lack of certain capacities of LSACs might hinder the creation of enabling conditions for transformative change within the food and finance sectors.

Coalitions consisting of powerful actors have a range of transformative capacities that, under certain conditions, can support systemic transformations within their sectors.
