Forskningsöversikt (refereegranskat)abstract
- Since antiquity, philosophers in the Western tradition of virtue ethics have declared practical wisdom to be the central virtue of citizens involved in public and social life. Practical wisdom is of particular importance when values are conflicting, power is unequal and knowledge uncertain. We propose that practical wisdom and virtue ethics can inform the practice of sustainability researchers by strengthening their capacity to engage with the normative complexities of knowledge co-production when aspiring to contribute to transformative change.

Vulnerability of blue foods to human-induced environmental change
- 2023
-
Ingår i: Nature Sustainability. - 2398-9629. ; 6, s. 1186-1198
-
Tidskriftsartikel (refereegranskat)abstract
- Global aquatic foods are a key source of nutrition, but how their production is influenced by anthropogenic environmental changes is not well known. The vulnerability of global blue food systems to main environmental stressors and the related spatial impacts across blue food nations are now quantified. Global aquatic or 'blue' foods, essential to over 3.2 billion people, face challenges of maintaining supply in a changing environment while adhering to safety and sustainability standards. Despite the growing concerns over their environmental impacts, limited attention has been paid to how blue food production is influenced by anthropogenic environmental changes. Here we assess the vulnerability of global blue food systems to predominant environmental disturbances and predict the spatial impacts. Over 90% of global blue food production faces substantial risks from environmental change, with the major producers in Asia and the United States facing the greatest threats. Capture fisheries generally demonstrate higher vulnerability than aquaculture in marine environments, while the opposite is true in freshwater environments. While threats to production quantity are widespread across marine and inland systems, food safety risks are concentrated within a few countries. Identifying and supporting mitigation and adaptation measures in response to environmental stressors is particularly important in developing countries in Asia, Latin America and Africa where risks are high and national response capacities are low. These findings lay groundwork for future work to map environmental threats and opportunities, aiding strategic planning and policy development for resilient and sustainable blue food production under changing conditions.

Earth system justice needed to identify and live within Earth system boundaries
- 2023
-
Ingår i: Nature Sustainability. - : Springer Science and Business Media LLC. - 2398-9629. ; 6:6, s. 630-638
-
Tidskriftsartikel (refereegranskat)abstract
- Living within planetary limits requires attention to justice as biophysical boundaries are not inherently just. Through collaboration between natural and social scientists, the Earth Commission defines and operationalizes Earth system justice to ensure that boundaries reduce harm, increase well-being, and reflect substantive and procedural justice. Such stringent boundaries may also affect ‘just access’ to food, water, energy and infrastructure. We show how boundaries may need to be adjusted to reduce harm and increase access, and challenge inequality to ensure a safe and just future for people, other species and the planet. Earth system justice may enable living justly within boundaries.

Energy production and water savings from floating solar photovoltaics on global reservoirs
- 2023
-
Ingår i: Nature Sustainability. - : Springer Science and Business Media LLC. - 2398-9629. ; 6, s. 865-874
-
Tidskriftsartikel (refereegranskat)abstract
- Solutions that can support multiple sustainability goals related to clean energy, and resource use efficiency, will be crucial in the near future. The study estimates the potential of floating solar panels on reservoirs globally to generate renewable energy, reduce water losses and conserve land. Growing global energy use and the adoption of sustainability goals to limit carbon emissions from fossil fuel burning are increasing the demand for clean energy, including solar. Floating photovoltaic (FPV) systems on reservoirs are advantageous over traditional ground-mounted solar systems in terms of land conservation, efficiency improvement and water loss reduction. Here, based on multiple reservoir databases and a realistic climate-driven photovoltaic system simulation, we estimate the practical potential electricity generation for FPV systems with a 30% coverage on 114,555 global reservoirs is 9,434 +/- 29 TWh yr(-1). Considering the proximity of most reservoirs to population centres and the potential to develop dedicated local power systems, we find that 6,256 communities and/or cities in 124 countries, including 154 metropolises, could be self-sufficient with local FPV plants. Also beneficial to FPV worldwide is that the reduced annual evaporation could conserve 106 +/- 1 km(3) of water. Our analysis points to the huge potential of FPV systems on reservoirs, but additional studies are needed to assess the potential long-term consequences of large systems.

A geospatial approach to understanding clean cooking challenges in sub-Saharan Africa
- 2023
-
Ingår i: Nature Sustainability. - : Springer Nature. - 2398-9629. ; 6:4, s. 447-457
-
Tidskriftsartikel (refereegranskat)abstract
- Universal clean cooking is a key target under Sustainable Development Goal (SDG) 7, with implications for several other SDGs, such as good health, gender equality and climate. Yet, 2.4 billion people globally still lack access to clean cooking. The situation is especially dire in sub-Saharan Africa (SSA), where only 17% use clean options. We develop OnStove, an open-source spatial tool comparing the relative potential of different cookstoves on the basis of their costs and benefits, and apply it to SSA. Our results suggest a severe market failure as the currently most used solution, traditional biomass, produces the lowest social net-benefits nearly everywhere in SSA. Correcting this failure, which stems from multiple market and behavioural obstacles, would deliver significant health, time and emission benefits but requires identification and promotion of policies to transform cooking energy use. Spatial mapping offers a more nuanced understanding of the costs needed to deliver cleaner cooking transitions than was previously possible, which is useful for improved targeting of intervention strategies.

The wider the gap between rich and poor the higher the flood mortality
- 2023
-
Ingår i: Nature Sustainability. - : Springer Nature. - 2398-9629.
-
Tidskriftsartikel (refereegranskat)abstract
- Economic inequality is rising within many countries globally, and this can significantly influence the social vulnerability to natural hazards. We analysed income inequality and flood disasters in 67 middle- and high-income countries between 1990 and 2018 and found that unequal countries tend to suffer more flood fatalities. This study integrates geocoded mortality records from 573 major flood disasters with population and economic data to perform generalized linear mixed regression modelling. Our results show that the significant association between income inequality and flood mortality persists after accounting for the per-capita real gross domestic product, population size in flood-affected regions and other potentially confounding variables. The protective effect of increasing gross domestic product disappeared when accounting for income inequality and population size in flood-affected regions. On the basis of our results, we argue that the increasingly uneven distribution of wealth deserves more attention within international disaster-risk research and policy arenas.

Principles for transformative ocean governance
- 2023
-
Ingår i: NATURE SUSTAINABILITY. - 2398-9629. ; 6:12, s. 1587-1599
-
Tidskriftsartikel (refereegranskat)abstract
- With a focus on oceans, we collaborated across ecological, social and legal disciplines to respond to the United Nations call for transformation in the '2030 Agenda for Sustainable Development'. We developed a set of 13 principles that strategically and critically connect transformative ocean research to transformative ocean governance (complementing the UN Decade for Ocean Science). We used a rigorous, iterative and transparent consensus-building approach to define the principles, which can interact in supporting, neutral or sometimes conflicting ways. We recommend that the principles could be applied as a comprehensive set and discuss how to learn from their interactions, particularly those that reveal hidden tensions. The principles can bring and keep together partnerships for innovative ocean action. This action must respond to the many calls to reform current ocean-use practices which are based on economic growth models that have perpetuated inequities and fuelled conflict and environmental decline. The UN 2030 Agenda for Sustainable Development recognizes the need to transform governance for the world to develop sustainably. Using a mixed method approach, this study presents 13 principles for transformative ocean governance that can help turn ocean-use practices into more sustainable ones.

Impacts of meeting minimum access on critical earth systems amidst the Great Inequality
- 2023
-
Ingår i: Nature Sustainability. - : Springer Science and Business Media LLC. - 2398-9629. ; 6:2, s. 212-221
-
Tidskriftsartikel (refereegranskat)abstract
- The Sustainable Development Goals aim to improve access to resources and services, reduce environmental degradation, eradicate poverty and reduce inequality. However, the magnitude of the environmental burden that would arise from meeting the needs of the poorest is under debate—especially when compared to much larger burdens from the rich. We show that the ‘Great Acceleration’ of human impacts was characterized by a ‘Great Inequality’ in using and damaging the environment. We then operationalize ‘just access’ to minimum energy, water, food and infrastructure. We show that achieving just access in 2018, with existing inequalities, technologies and behaviours, would have produced 2–26% additional impacts on the Earth’s natural systems of climate, water, land and nutrients—thus further crossing planetary boundaries. These hypothetical impacts, caused by about a third of humanity, equalled those caused by the wealthiest 1–4%. Technological and behavioural changes thus far, while important, did not deliver just access within a stable Earth system. Achieving these goals therefore calls for a radical redistribution of resources.

Shaping a resilient future in response to COVID-19
- 2023
-
Ingår i: Nature Sustainability. - 2398-9629. ; :6, s. 897-907
-
Tidskriftsartikel (refereegranskat)abstract
- Science today defines resilience as the capacity to live and develop with change and uncertainty, which is well beyond just the ability to ‘bounce back’ to the status quo. It involves the capacity to absorb shocks, avoid tipping points, navigate surprise and keep options alive, and the ability to innovate and transform in the face of crises and traps. Five attributes underlie this capacity: diversity, redundancy, connectivity, inclusivity and equity, and adaptive learning. There is a mismatch between the talk of resilience recovery after COVID-19 and the latest science, which calls for major efforts to align resilience thinking with sustainable development action.

Quantifying timber illegality risk in the Brazilian forest frontier
- 2023
-
Ingår i: Nature Sustainability. - 2398-9629. ; 6:11, s. 1485-1495
-
Tidskriftsartikel (refereegranskat)abstract
- Illegal logging remains widespread across the tropics, leading to extensive forest degradation and trade in illegal timber products. By adapting environmentally extended input–output modelling to timber originating from Brazilian native forests, we demonstrate how distinct illegality risks can be mapped and quantified at species-level across the supply chain. We focus on high-value ipê hardwood from the Amazon state of Pará, a leading producer of timber and contested forest frontier. Data on logging permits and state- and national-level Document of Forest Origin licences are used to estimate illegality risks due to missing or invalid logging permits, overstated ipê yields or discrepancies resulting from missing inflows of legal timber. We find that less than a quarter of all ipê entering supply chains between 2009 and 2019 is risk-free and highlight diversified strategies for the laundering of illegal timber across geographies. While legality does not ensure sustainability, this information can be leveraged to this end by supporting improved implementation and enforcement of forest regulations.

Urban water crises driven by elites' unsustainable consumption
- 2023
-
Ingår i: Nature Sustainability. - : Springer Nature. - 2398-9629. ; 6:8, s. 929-940
-
Tidskriftsartikel (refereegranskat)abstract
- Over the past two decades, more than 80 metropolitan cities across the world have faced severe water shortages due to droughts and unsustainable water use. Future projections are even more alarming, since urban water crises are expected to escalate and most heavily affect those who are socially, economically and politically disadvantaged. Here we show how social inequalities across different groups or individuals play a major role in the production and manifestation of such crises. Specifically, due to stark socioeconomic inequalities, urban elites are able to overconsume water while excluding less-privileged populations from basic access. Through an interdisciplinary approach, we model the uneven domestic water use across urban spaces and estimate water consumption trends for different social groups. The highly unequal metropolitan area of Cape Town serves as a case in point to illustrate how unsustainable water use by the elite can exacerbate urban water crises at least as much as climate change or population growth.

Response diversity as a sustainability strategy

Tidskriftsartikel (refereegranskat)abstract
- Financial advisers recommend a diverse portfolio to respond to market fluctuations across sectors. Similarly, nature has evolved a diverse portfolio of species to maintain ecosystem function amid environmental fluctuations. In urban planning, public health, transport and communications, food production, and other domains, however, this feature often seems ignored. As we enter an era of unprecedented turbulence at the planetary level, we argue that ample responses to this new reality — that is, response diversity — can no longer be taken for granted and must be actively designed and managed. We describe here what response diversity is, how it is expressed and how it can be enhanced and lost.
