Global patterns in water flux partitioning : Irrigated and rainfed agriculture drives asymmetrical flux to vegetation over runoff
- 2023
-
Ingår i: One Earth. - 2590-3330 .- 2590-3322. ; 6:9, s. 1246-1257
-
Tidskriftsartikel (refereegranskat)abstract
- The partitioning of precipitation water input on land between green (evapotranspiration) and blue (runoff) water fluxes distributes the annually renewable freshwater resource among sectors and ecosystems. The patterns and main drivers of this partitioning are not fully understood around the global land area. We decipher the worldwide patterns and key determinants of this water flux partitioning and investigate its predictability based on a global machine learning model. Available data for 3,614 hydrological catchments and model application to the global land area agree in showing mostly larger green than blue water flux. Possible expansion/intensification of irrigated and/or rainfed agriculture to feed a growing human population, along with climate warming, will tend to increase this flux partitioning asymmetry, jeopardizing blue water security. The developed machine learning model presents a promising predictive tool for future blue and green water availability under various forthcoming climate and land-use change scenarios around the world.

Eighty-six EU policy options for reducing imported deforestation
- 2021
-
Ingår i: One Earth. - : Elsevier BV. - 2590-3322 .- 2590-3330. ; 4:2, s. 289-306
-
Tidskriftsartikel (refereegranskat)abstract
- Despite the importance of tropical forest conservation in achieving global sustainability goals and the key role of forest-risk commodity trade in driving deforestation, consumer country policy options for reducing imported deforestation have received limited scholarly attention. Drawing on gray literature and a European Commission public consultation, we identify 86 policy options for the European Union to address deforestation. We assess the political feasibility and map the “theory of change” (TOC)—the causal chain through which the policies address deforestation—for each of these policy options, identifying a trade-off between feasibility and potential impacts: information-based and cooperative policies, which dominate our sample, typically exhibit high feasibility, but mostly lack convincing TOCs, while more stringent regulatory and market-based policy options generally have lower feasibility. We propose three principles for overcoming the feasibility-impact dilemma: (1) build policies on proven TOCs, (2) use policy mixes, and (3) work with key stakeholders, supply chains, and regions. Images of distressed orangutans in Indonesia and forest fires in Brazil have increased public awareness of deforestation across the globe. Still, deforestation continues more or less unabated, driven by demand for forest-risk commodities, such as palm, soy, cocoa, and beef. What can the European Union (EU) and other consumer regions do to address this problem? Here we present 86 policy options for the EU to address tropical deforestation, identified through a review of gray literature and EU stakeholder consultation responses. Analyzing these, we show that policy options that are politically feasible policies tend to have a weaker theory of change—the causal chain through which the policies address deforestation—setting up a trade-off between feasibility and impact. However, there are exceptions, such as mandatory due diligence, which show potential impact and appear politically feasible. Through policy mixing and working with key stakeholders, supply chains, and producer regions, these barriers can be overcome. Images of distressed orangutans in Indonesia and forest fires in Brazil have increased public awareness of deforestation. Still, deforestation continues unabated, driven by demand for forest-risk commodities, such as palm and soy. Here, we present 86 policy options for the EU to reduce imported deforestation. We identify a trade-off between policy feasibility and potential impact. Mixing different policies and working with key stakeholders, supply chains, and producer regions can help overcome this trade-off.

Plastics and climate change breaking carbon lock-ins through three mitigation pathways
- 2022
-
Ingår i: One Earth. - : Elsevier BV. - 2590-3330 .- 2590-3322. ; 5:4, s. 361-376
-
Forskningsöversikt (refereegranskat)abstract
- The plastic industry is dependent on fossil fuels in various ways that result in strong “carbon lock-in” throughout the value chain and large and growing CO2 emissions. The industry must decarbonize to reach global net-zero pledges. Although a few initiatives have been launched, they primarily focus on plastic waste. Current research has investigated mitigation potential on different parts of the plastic value chain but remains in silos. Here, we review carbon lock-ins throughout the plastic value chain and identify possible mitigation pathways for each stage of the plastic life cycle. We show how lock-ins are stubbornly entrenched across the domains of production, markets, waste management, industry organization, and governance. Overcoming these carbon lock-ins and achieving zero-carbon targets for the sector by 2050 will require thorough systemic change to how plastics are produced, used, and recycled, including promotion of demand reduction strategies, bio-based feedstocks, and circular economy principles. Strict governance structures, enforceable regulation, and a new proactive and inclusive vision for the low-carbon transition are equally important.

Forskningsöversikt (refereegranskat)abstract
- The Sustainable Development Goals (SDGs) set a vision for a more sustainable world, to be realized by 2030. Progress to date is insufficient and implementation challenges are many, including the need for strategies that maximize synergies and mitigate trade-offs and conflicts among the goals. This scoping review synthesizes 51 recent scientific articles on interlinkages, with findings that can help decision-makers address this challenge. We identify recurring patterns of SDG interlinkages, including SDGs that promote other SDGs (e.g., SDGs 4, 6, and 17) and those at risk due to negative impacts from progress in other areas (e.g., SDGs 14 and 15). Such patterns can inform national and local implementation. Further research is needed to clarify the systemic roles of some SDGs (e.g., SDGs 10-12), understand causal relationships, and assess policy options. We make six recommendations for science to make interlinkages knowledge more accessible and for decision-makers to systematically use this knowledge.

Reshaping the European agro-food system and closing its nitrogen cycle: The potential of combining dietary change, agroecology, and circularity
- 2021
-
Ingår i: One Earth. - : Elsevier BV. - 2590-3322 .- 2590-3330. ; 4:6, s. 839-850
-
Forskningsöversikt (refereegranskat)abstract
- After World War II, the evolution of Europe's agro-food system has been marked by intensified use of synthetic fertilizers, territorial specialization, and integration in global food and feed markets. This evolution led to increased nitrogen (N) losses to aquatic environments and the atmosphere, which, despite increasing environmental regulations, continues to harm ecosystems and human well-being. Here, we explore how these N losses can be drastically reduced in a scenario synergistically operating three levers: (1) a dietary change toward less animal products and an efficient recycling of human excreta; (2) the generalization of region-specific organic crop rotation systems involving N2-fixing legumes, making it possible to do without synthetic N fertilizers; and (3) the reconnection of livestock with cropping systems allowing optimal use of manure. This scenario demonstrates the possibility to feed the projected European population in 2050 without imports of feed and with half the current level of environmental N losses.

Loss and damage from climate change: A new climate justice agenda
- 2021
-
Ingår i: One Earth. - : Elsevier BV. - 2590-3330 .- 2590-3322. ; 4:10, s. 1365-1370
-
Tidskriftsartikel (refereegranskat)abstract
- The effects of climate change, whether they be via slow- or rapid-onset events such as extreme events, are inflicting devastating losses and damage on communities around the world, with the most vulnerable affected the most. Although the negative impacts of climate change and the concept of loss and damage are included in international conventions, such as the United Nations Warsaw International Mechanism for Loss and Damage and Article 8 of the Paris Agreement, these stop short of providing clear compensation mechanisms. The science of loss and damage has evolved with the development of extreme event attribution science, which assesses the probability of an extreme event being influenced by anthropogenic greenhouse gas emissions, but loss and damage still suffers from the lack of a clear definition and measurability and is further complicated by debates on climate justice and shared but differentiated responsibilities. This primer presents an overview of loss and damage, discusses the complexities and knowledge gaps, and proposes next steps for an interdisciplinary research agenda.

Who is the high seas fishing industry?
- 2020

Tidskriftsartikel (refereegranskat)abstract
- Seafood companies rarely disclose what or where they are fishing. To provide a first overview of the fishing industry in the high seas-the area beyond national jurisdiction-we linked fishing activity in the high seas to vessel owners and corporate actors. We identified 1,120 corporate actors for 2,482 vessels (similar to 2/3 of high seas fishing vessels and effort in 2018) and found that the top 100 corporate actors account for 36% of all high seas fishing effort. As attribution for anthropogenic activities expands beyond a national framework, we demonstrate the feasibility of methods to identify the high seas fishing industry. These results provide a unique lens through which to view accountability for the use and protection of marine biodiversity.

Deep-ocean seaweed dumping for carbon sequestration: Questionable, risky, and not the best use of valuable biomass
- 2024

Tidskriftsartikel (refereegranskat)abstract
- Deep-ocean seaweed dumping is not an ecological, economical, or ethical answer to climate-change mitigation via carbon “sequestration.” Without sound science and sufficient knowledge on impacts to these fragile ecosystems, it distracts from more rational and effective blue-carbon interventions. We call for a moratorium on sinking seaweeds to deep-ocean ecosystems until its efficacy is established, and there is robust, evidence-based assessment of its environmental, economic, and societal sustainability.

China at a Crossroads : An Analysis of China's Changing Seafood Production and Consumption

-
Tidskriftsartikel (refereegranskat)abstract
- China is a key player in global production, consumption, and trade of seafood. Given this dominance, Chinese choices regarding what seafood to eat, and how and where to source it, are increasingly important—for China, and for the rest of the world. This perspective explores this issue using a transdisciplinary approach and discusses plausible trajectories and implications for assumptions of future modeling efforts and global environmental sustainability and seafood supply. We outline China's 2030 projected domestic seafood production and consumption through an examination of available statistics, and qualitatively evaluate these in relation to key stated Chinese policy targets, consumer trends, and dominant political narratives. Our analysis shows that by 2030 China is likely to see seafood consumption outstrip domestic production. To meet the seafood gap China will likely attempt to increase domestic freshwater and offshore aquaculture, increase seafood imports, possibly expand the distant water fishing industry, and invest in seafood production abroad.

The Anthropocene reality of financial risk

Forskningsöversikt (refereegranskat)abstract
- Globally, financial services are well positioned to contribute to the transformation needed for sustainable futures and will be critical for supporting corporate activities that regenerate and promote biosphere resilience as a key strategy to confront the new risk landscape of the Anthropocene. While current financial risk frameworks focus primarily on financial materiality and risks to the financial sector, failure to account for investment externalities will aggravate climate and other environmental change and set current sustainable finance initiatives off course. This article unpacks the cognitive disconnect in financial risk frameworks between environmental and financial risk. Through analysis of environmental, social, and governance ratings and estimates of global green investments, we exemplify how the cognitive disconnect around risk plays out in practice. We discuss what this means for the ability of society at large, and finance in particular, to deliver on sustainability ambitions and global goals.

Voluntary commitments made by the world’s largest companies focus on recycling and packaging over other actions to address the plastics crisis
- 2022
-
Ingår i: One Earth. - : Elsevier BV. - 2590-3330 .- 2590-3322. ; 5:11, s. 1286-1306
-
Tidskriftsartikel (refereegranskat)abstract
- Plastic pollution has caused significant environmental and health challenges. Corporations that contribute to the manufacture, use, and distribution of plastics can play a vital role in addressing global plastic pollution and many are committing to voluntary pledges. However, the extent to which corporations’ voluntary commitments are helping solve the problem remains underexplored. Here, we develop a novel typology to characterize voluntary commitments to reduce plastic pollution made between 2015 and 2020 by 973 companies, including the top 300 of the Fortune Global 500. We find that 72% of these companies have made some form of commitment(s) to reduce plastic pollution. About 67% of companies participating in voluntary environmental programs (VEPs) and 17% of non-VEP participants made measurable and timebound commitments. However, rather than tackle virgin plastics, most companies target packaging and general plastics and frequently emphasize recycling-related efforts. Growing commitments on plastic pollution are made by large and important companies, but significantly more efforts beyond plastic recycling are required to effectively address plastic pollution challenges.

An applied research agenda for navigating diverse livelihood challenges in rural coastal communities in the tropics
- 2022
-
Ingår i: One Earth. - : Elsevier BV. - 2590-3330 .- 2590-3322. ; 5:11, s. 1205-1215
-
Tidskriftsartikel (refereegranskat)abstract
- Rural, tropical coastal communities are experiencing sustained, often increasing food insecurity, poverty, and global change impacts. These challenges have stimulated a rise in projects aiming to enhance and diversify local livelihoods. The ability of these projects to achieve broad-scale benefits is limited by approaches that do not account for feedbacks among sectors and across marine and terrestrial environments. To address these limitations, we present an applied research agenda to support an integrated approach to livelihood project planning and management. This agenda explicitly examines interactions among natural resources, industries, and livelihoods and is based on three foundational activities: (1) a governance review and assessment, (2) strategic partnership formation, and (3) a diagnostic approach supported by science and shared outcomes. We add structure to the established logic in our field by broadening the sectoral and spatial scope of livelihoods projects, so they can better contribute to interrelated UN Sustainable Development Goals.

Ozone-related acute excess mortality projected to increase in the absence of climate and air quality controls consistent with the Paris Agreement

Tidskriftsartikel (refereegranskat)abstract
- Short-term exposure to ground-level ozone in cities is associated with increased mortality and is expected to worsen with climate and emission changes. However, no study has yet comprehensively assessed future ozone-related acute mortality across diverse geographic areas, various climate scenarios, and using CMIP6 multi-model ensembles, limiting our knowledge on future changes in global ozone-related acute mortality and our ability to design targeted health policies. Here, we combine CMIP6 simulations and epidemiological data from 406 cities in 20 countries or regions. We find that ozone-related deaths in 406 cities will increase by 45 to 6,200 deaths/year between 2010 and 2014 and between 2050 and 2054, with attributable fractions increasing in all climate scenarios (from 0.17% to 0.22% total deaths), except the single scenario consistent with the Paris Climate Agreement (declines from 0.17% to 0.15% total deaths). These findings stress the need for more stringent air quality regulations, as current standards in many countries are inadequate.

However, this system has also engendered a series of wicked problems and externalities, including but not limited to climate change, environmental pollution, biodiversity loss, and inequalities that significantly challenge the well-being of nature and people. The system is also currently inadequate with regards to financing sustainable development, as recognized by the 2015 Addis Ababa Action Agenda. This Voices asks: what must be done to transform today's financial system for a sustainable future?

A water-function-based framework for understanding and governing water resilience in the Anthropocene
- 2021

Ingår i: One Earth. - : Elsevier BV. - 2590-3330 .- 2590-3322. ; 4:2, s. 213-225
-
Tidskriftsartikel (refereegranskat)abstract
- The freshwater cycle over land is fundamental for sustainability and resilience, yet is extensively modified and shaped by a vast range of human interventions in the land, water, and climate systems. The consequences of human water-cycle modifications can be non-linear, delayed, and distributed across boundaries, sectors, and scale. This complexity renders freshwater challenges difficult to govern and manage. We here propose a framework for understanding water's many functions for supporting, regulating, and stabilizing hydro-climatic, hydro-ecological, and hydro-social systems. This framework recognizes human impacts on major partitioning points, interactions among water functions, and stabilization and destabilization processes. A functional understanding of the freshwater cycle can integrate with social-ecological resilience-building principles, complement existing water sustainability governance approaches, and highlight the potential need for Earth-system-level governance of water. Recognizing water's diverse functional roles for resilience may promote a new generation of holistic and integrative water- land-climate governance.

Blind spots in visions of a blue economy could undermine the ocean's contribution to eliminating hunger and malnutrition

-
Tidskriftsartikel (refereegranskat)abstract
- Increasing the production of food from the ocean is seen as a pathway toward more sustainable and healthier human diets. Yet this potential is being overshadowed by competing uses of ocean resources in an accelerating blue economy.'' The current emphasis on production growth, rather than equitable distribution of benefits, has created three unexamined or flawed assumptions that growth in the blue economy will lead to growth in blue food'' production, increased production will inevitably lead to improved food and nutrition security, and mariculture production will replace marine capture fisheries. In this perspective, we argue that if research and policies are pursued without addressing these blind spots,'' blue food contributions to reducing hunger and malnutrition, and to meeting the Sustainable Development Goals, will be limited. Taking a broader food-system approach beyond production to also considering food access, affordability, and consumption will refocus the blue food agenda on making production and consumption more equitable and sustainable while increasing access for those who need it most.

Operationalizing Ocean Health : Toward Integrated Research on Ocean Health and Recovery to Achieve Ocean Sustainability

-
Tidskriftsartikel (refereegranskat)abstract
- Protecting the ocean has become a major goal of international policy as human activities increasingly endanger the integrity of the ocean ecosystem, often summarized as “ocean health.” By and large, efforts to protect the ocean have failed because, among other things, (1) the underlying socio-ecological pathways have not been properly considered, and (2) the concept of ocean health has been ill defined. Collectively, this prevents an adequate societal response as to how ocean ecosystems and their vital functions for human societies can be protected and restored. We review the confusion surrounding the term “ocean health” and suggest an operational ocean-health framework in line with the concept of strong sustainability. Given the accelerating degeneration of marine ecosystems, the restoration of regional ocean health will be of increasing importance. Our advocated transdisciplinary and multi-actor framework can help to advance the implementation of more active measures to restore ocean health and safeguard human health and well-being.
