The transport of non-petroleum substances such as vegetable oils, other bio-based oils and their refined products by chemical tankers is increasing worldwide. The majority of the non-petroleum substances carried by chemical tankers will have detrimental effects on the marine environment if accidentally spilled or discharged during tank washing procedures. Swedish Coast Guard aircrafts detected 233 discharges of floating non-petroleum substances in the Swedish territorial sea and Swedish Exclusive Economic Zone (EEZ) between 2020 and 2023. The majority of the discharges, 84%, were detected in the EEZ. About 14% of the discharges were detected within protected marine Natura 2000 sites. Together, the detected discharges covered 1071 km² of sea surface. Discharges in marine Natura 2000 sites covered 228 km². We conclude that the regulations in the IMO MARPOL Annex II convention are not strict enough to meet the objectives of EU nature legislation regarding protection of sensitive seas areas.

In many transdisciplinary research settings, a lack of attention to the values underpinning project aims can inhibit stakeholder engagement and ultimately slow or undermine project outcomes. As a research collective (The Careoperative), we have developed a set of four shared values through a facilitated visioning process, as central to the way we work together: care, reflexivity, inclusivity, and collectivity. In this paper, we explore the implications of a values-centered approach to collaboration in food system transformation research. The paper presents two cases that illustrate how researchers might approach centering values in practice. Where much research on food system transformation focuses on values of food system stakeholders, we contribute insights into the values of researchers in such transdisciplinary endeavors. Specifically, we argue that researchers working on sustainability transformations need to be better prepared to engage in such reflections and aspire to embody values aligned with the transformations they seek to research.

To address climate change and global biodiversity loss, the world must hit three important international conservation targets by 2030: protect 30% of terrestrial and marine areas, halt and reverse forest loss, and restore 350 Mha of degraded and deforested landscapes. Here, we (1) provide estimates of the gaps between these globally agreed targets and business-as-usual trends; (2) identify examples of rapid past trend-shifts towards achieving the targets; and (3) link these past trend-shifts to different levers. Our results suggest that under a business-as-usual scenario, the world will fail to achieve all three targets. However, trend-shifts that rapidly "bend the curve" have happened in the past and these should therefore be fostered. These trend-shifts are linked to transformative change levers that include environmental governance, economic factors, values, and knowledge. Further research on trend-shifts, as well as bold action on underlying levers, is urgently needed to meet 2030 global conservation targets.

In this perspective, we present and discuss four major causes of the worldwide nature conservation failure: 1) ideologies based on nature-culture dualism, 2) the bias prioritising forests in conservation, 3) the illusory objectiveness of selected biological indicators, and 4) the mismanagement of rural agricultural landscapes. All of these relate to ignorance of historical ecology and neglect of the role past plays in shaping landscapes and fostering biodiversity. These led to a false anthropology focussed on the broader human economy (including agriculture) as the absolute culprit of biodiversity loss. It is believed, therefore, that biodiversity preservation depends on conservation policies and actions providing protection against human activities, such as farming. In this way, nature conservation has been detached from the rich experiences of long and fruitful coexistence of people with other elements of nature. The bio-cultural legacy includes biodiversity-rich rural landscapes, whose habitats are often either neglected or wrongly interpreted as "remnants of natural ecosystems". Consequently, conservation efforts are frequently ineffective or worse still, counter-effective. In the face of policies favouring subsidised intensive agribusiness at the cost of destroying smallholder family farming, even expensive conservation projects are usually nothing more than a "fig leaf" to cover failure. We advocate re-focussing of conservation planning to put more emphasis on landscapes' historical ecology responsible for their bio-cultural diversity. It implies the need for new principles in policies necessary to secure the economic and cultural sovereignty of local socio-ecological systems responsible for the world's bio-cultural diversity.

The 2004 tsunami and coastal subsidence resulted in 97% mangrove loss in the Nicobar Islands (India), leading to major social-ecological change. We assessed how the Nicobar mangrove social-ecological system (SES) responded to the 2004 event using the adaptive cycle (AC) framework. We describe the changes across AC phases (collapse-Ω, reorganisation-α, growth-r, and conservation-K) concerning various capital types (natural, built, human, social), connectedness and resilience. The subsidence and tsunami triggered a rapid collapse (Ω) in the mangrove SES, particularly depleting natural and built capitals. Despite declines in social and human capital, some knowledge and skills were retained within Nicobari communities. We suggest that locally managed interventions involving mangrove restoration are critical to escape the poverty trap caused by resource insufficiency hindering growth. The AC model helps visualise and describe temporal changes, preparing for recovery challenges. This approach is relevant to SESs beyond Nicobar, offering insights for sites confronting similar social-ecological dynamics and challenges.

Climate change is causing rapid warming in the Arctic, which, alongside other physical, socio-economic, cultural, geopolitical, and technological factors, is driving change in the far north. This research presents a conceptual model summarizing Arctic change factors which in turn was used in the design of a Delphi exercise which leveraged a variety of experts to forecast trajectories in different parts of the Arctic. Based on these experts' expectations for economic and governance outcomes by 2050, we find that our results illustrate the "many Arctics" concept or some of the ways in which the Arctic is heterogenous now, and perhaps becoming increasingly so in the future. Sub-regions of the Arctic differed in expert expectations about the future of resource extraction, tourism, Indigenous self-determination, and military activity, among other outcomes. This work also discusses the post-2022 geopolitical situation and some potential implications of "many Arctics" for policy and future governance.

While policy interest and research on recreational ecosystem services (RES) has increased substantially, insights into the actual flows of benefits to people have remained scarce, especially at levels beyond local communities. This paper aims to model RES Flows and Benefits for Germany in monetary and non-monetary terms. We use Germany as a case study due its diversity of landscapes and availability of relevant spatial and empirical data. We develop and apply an assessment approach that considers RES Demand and Supply based on user preferences. Our results show distinct demand-supply matches and mismatches, for example in southwest Germany, and highest flows near population centres. Monetary benefits are highest in counties with high RES Supply that are close to densely populated areas. Our results can usefully inform planning and decision-making, for example to improve and further justify destination management, landscape development, and investments in RES at local, regional, and national levels.
