Mountains and highlands are not what scholars have conventionally imagined them to be: environments that limit and constrain their inhabitants in deterministic ways. Rather, mountains and highlands provide unique opportunities for people to engage in creative transformation of their societies. Highland communities are connected to a wider world, and they radically remake and experiment with their landscapes, settlements, and societies. Mountains serve as birthplaces and testing grounds for statecraft, urbanism, irrigation, and monumental landscape engineering. Here we explore the diversity of highland communities by analysing the latest archaeological and historical discoveries from three regions across Southeast Asia: the Kulen mountains (Cambodia), the volcanoes of central Java (Indonesia), and the Ifugao highlands (the Philippines). We find that, far from being a negative image of the ‘civilized’ lowlands, mountains were creative, diverse, dynamic, and well-connected places. This compels us to change the way we conceive of today’s highland communities and their relationships to modern nation-states.

In the face of the triple planetary crisis, which includes climate change, biodiversity loss and environmental degradation, there is growing recognition that the environment needs to be re-evaluated and better protected. Recent developments, such as a values assessment by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES),1 the concept of biocultural rights and the acknowledgment of granting rights to nature, emphasize the intrinsic value of the environment and endorse the understanding of the interconnectedness between humans and non-human entities. These developments are also increasingly evident in legal frameworks; for instance, several domestic legal systems now accept the rights of nature and grant legal standing to natural entities. This expansion in our understanding of the environment challenges the traditional anthropocentric focus of international law, which has primarily prioritized human rights and interests, perceiving humans as having dominance over nature and the liberty to harness its resources. Simultaneously, international environmental law is increasingly recognizing the interdependence of ecosystems and species. This acknowledgment drives the promotion of approaches to environmental management and conservation that centre around ecosystems and local communities. The present article looks at how to reconcile these heightened environmental values and the legal norms in armed conflict by examining two examples: the safeguarding of protected areas and the restoration of the environment post-conflict. By analyzing the changing values and legal developments in this area, the article offers legal and practical tools to support the protection of nature's intrinsic value in future warfare.

Contemporary ecological and climate crises have thrown into sharp relief debates around what roles and responsibilities, if any, international security bodies ought to have in addressing environment-related matters. Building on a wider catalogue of the United Nations Security Council's practice concerning the environment, in this article, we provide a snapshot of the Council's practice pertaining in particular to the environment and armed conflict. In addition to setting out key aspects relating to the personal, geographical and temporal scope of that practice, we identify four armed-conflict-related substantive themes arising in the Security Council's actions in this area: (1) relations between conflict and natural resources; (2) relations between conflict and adverse environment-related phenomena; (3) relations between conflict and chemical and biological weapons; and (4) adverse impacts of conflict on the environment. Through this examination, we aim in part to provide stakeholders with a more extensive and detailed basis on which to evaluate what actions the Council has taken – and, by inference, which actions it has not taken – with respect to the environment and armed conflict.

Afin de mieux comprendre la distribution géographique des facilitateurs et des obstacles à la participation sociale des Québécois âgés, cette étude visait à documenter l’Indice du potentiel de participation sociale (IPPS) selon les zones métropolitaines, urbaines et rurales. Des analyses de données secondaires, dont l’Enquête transversale sur la santé des collectivités canadiennes, ont permis de développer et de cartographier un indice composé de facteurs environnementaux associés à la participation sociale, pondérés par une analyse factorielle. En zones métropolitaines, l’IPPS était supérieur au centre qu’en périphérie, compte tenu d’une concentration accrue d’aînés et des transports. Bien qu’atténuée, la configuration était similaire en zones urbaines. En zone rurale, un IPPS élevé était associé à une concentration d’aînés et un accès aux ressources accru, sans configuration spatiale. Pour favoriser la participation sociale, l’IPPS soutient que les transports et l’accès aux ressources doivent respectivement être améliorés en périphérie des métropoles et en zone rurale.

Climate change is arguably the defining issue of our time, with global impacts. Yet to date, scholarship within social policy has remained relatively fragmented and disparate, leaving an urgent need to start comprehensively embedding environmental thinking across all domains of the discipline (Williams, 2021). Responding to this challenge, this paper draws together existing work at the nexus of social policy, the environment, and climate change. The paper then presents findings from workshops held with social policy scholars, policymakers, and practitioners, using these discussions to propose pathways to embed climate change within the discipline. The paper represents a significant contribution to knowledge within the field as it seeks to both broaden discussions about social policy and climate change; to identify theoretical and empirical relationships that exist between the two fields but have not been fully recognised in existing scholarship; and to bring new perspectives and voices into the discussion.

Dr Marja Lehto is Ambassador for International Legal Affairs at the Ministry for Foreign Affairs of Finland, and Adjunct Professor of International Law at the University of Helsinki. She was a member of the United Nations (UN) International Law Commission (ILC) and served as the Special Rapporteur for the topic “Protection of the Environment in Relation to Armed Conflicts” from 2017 to 2022. Dr Lehto is also a member of the Council of the International Institute of Humanitarian Law since 2019. She has formerly served, inter alia, as Legal Adviser to the Finnish UN Mission in New York (1995–2000), as Head of the Unit for Public International Law (2000–09), and as Finland's Ambassador to Luxembourg (2009–14). For most of her career, she has worked on issues related to international peace and security, including international criminal justice and international humanitarian law (IHL), and she has published on a broad range of international legal questions related to the law of the sea, international environmental law (IEL), State succession, use of force, armed conflicts, terrorism and cyber security.

The growth of access to the internet, wide availability of smart phones and increased public access to remote sensing data from hundreds of satellite systems have spurred a revolution in tracking the linkages between armed conflict and environmental damage. Over the last decade, a growing community of open-source investigative experts, environmentalists, academics and civil society groups have applied these methods to document war crimes, human rights violations and environmental degradation. These developments have created new opportunities for building accountability and transparency. The wealth of data on conflict-linked environmental damage has already been successfully leveraged to address acute and long-term environmental health risks and inform humanitarian response and post-conflict environmental assessments in Iraq, Syria and Ukraine. There are, however, larger questions on how to best make use of these data streams and information layers, and how to navigate the opportunities and limitations of these developments. This article will outline the new developments in this field and provide recommendations to ensure that data is used responsibly and effectively to strengthen accountability for environmental damages as a result of armed conflict.

Dissolved inorganic carbon (DIC) in ocean water is a major sink of fossil fuel derived CO2. Carbon isotopes in DIC serve as tracers for oceanic water masses, biogeochemical processes, and air-sea gas exchange. We present a timeseries of surface DIC δ13C and Δ14C values from 2011 to 2022 from Newport Beach, California. This is a continuation of previous timeseries (Hinger et al. 2010; Santos et al. 2011) that together provide an 18-year record. These data show that DIC Δ14C values have declined by 42‰ and that DIC δ13C values have declined by 0.4‰ since 2004. By 2020, DIC Δ14C values were within analytical error of nearby clean atmospheric CO2 Δ14C values. These long-term trends are likely the result of significant fossil fuel derived CO2 in surface DIC from air-sea gas exchange. Seasonally, Δ14C values varied by 3.4‰ between 2011 and 2022, where seasonal δ13C values varied by 0.7‰. The seasonal variation in Δ14C values is likely driven by variations in upwelling, surface eddies, and mixed layer depth. The variation in δ13C values appears to be driven by isotopic fractionation from marine primary producers. The DIC δ13C and Δ14C values record the influence of the drought that began in 2012, and a major upwelling event in 2016.

Infrastructure has been the focus of geopolitically significant regional strategies, including the Belt and Road Initiative and the Asian Highway. Mega-infrastructure projects are thought to offer crucial stimulus to support economic recovery and “infrastructure diplomacy” efforts. Transportation projects, like roads, are material objects that offer complex questions for international law, most obviously when projects or their impacts cross borders. They are long-term and long-distance, with varying impacts upon closer and further populations and environments across the construction and life of the asset. This article draws on insights from new materialism to analyse what infrastructure's entanglements might suggest about international law. The relationship between international law and transportation infrastructure is contingent. However, there is a pattern to this contingency that foregrounds funding “gaps”, investment protections, and risk assessments, which minimizes intersecting impacts and human/non-human relationships.
