Abstract and Figures

Every year, more people are killed defending the environment than are soldiers from the United Kingdom and Australia on overseas deployments in war zones combined. During the last 15 years, the number of both deaths of environmental defenders, and the countries where they occur, have increased. Recorded deaths have increased from two per week to four per week over this period. These deaths are primarily related to conflict over natural resources, across a range of sectors. Of 683 total deaths, >230 were related to mining and agribusiness between 2014 and 2017. We find that rule of law and corruption indices are closely linked to patterns of killings. Using spatial data, we investigate the drivers of these conflicts and violence and seek to identify who may be most at risk and why. We argue that businesses, investors and national governments at both ends of the chain of violence need to be more accountable.

Between 2002 and 2017, 1,558 people in 50 countries were killed
for defending their environments and lands1 (Supplementary
Table 1). This is more than double the number of United
Kingdom and Australian armed service people killed on active duty
in war zones over the same period (n = 697; refs. 2,3) and almost half
as many as the number of US soldiers killed in Iraq and Afghanistan
since 2001 (n = 4,044; ref. 4). ‘Environmental defenders’ here refers
to people engaged in protecting land, forests, water and other
natural resources. This includes community activists, members of
social movements, lawyers, journalists, non-governmental organi-
zation staff, indigenous peoples, members of traditional, peasant
and agrarian communities, and those who resist forced eviction
or other violent interventions. These people take peaceful action,
either voluntarily or professionally, to protect the environment
or land rights1. They may be directly involved in working on the
land, represent those who do, or be advocates for conservation of
habitats or species.
The forms of violence (direct, structural and cultural), and the
types of harm caused (for example, physical and psychological),
are examined in detail elsewhere57. We distinguish between large-
scale violence linked to armed conflicts (civil, guerrilla or interna-
tional) rooted in struggles over natural resources, and that aimed
at individuals or particular communities or groups of individuals
due to their acts of resistance and/or protection of their land or
environmental rights. Environmental defenders currently face a
wave of violence that includes threats of physical harm, intimida-
tion and criminalization8,9 (Fig. 1). We focus on the deaths of envi-
ronmental defenders, documented since 2002 by Global Witness
(UK), the Comissão Pastoral da Terra (Pastoral Land Commission,
Brazil), The Guardian (UK) and others. Deaths represent the ‘tip
of the iceberg’ of the violence that environmental defenders face.
For every defender murdered, thousands more face direct violence,
threats and psychological intimidation, and more invisible cultural
and structural violence (or ‘slow violence’)10. We examine the par-
ticular conditions, sectors and interactions leading to the deaths of
defenders. Using global datasets, we analyse the drivers of violence
contributing to these deaths. Other studies have looked at the links
between authoritarianism and deaths of environmental defenders11
and the relationship between economic growth and these deaths12.
We further this analysis by evaluating the relationship between
spatial factors (natural resource distribution such as hectares of
agricultural cultivation and area of mining concessions) and deaths
of environmental defenders.
Natural resource conflicts
Conflicts over natural resources are linked to different resources
and/or sectors (for example, fossil fuels, minerals, timber, agricul-
ture, aquaculture and water), as well as access to land and/or bod-
ies of water from which natural resources can be extracted13. These
conflicts can be seen as a continuation of colonial land and resource
appropriation that established systems of dispossession and con-
trol. Such appropriation includes: displacement, forced labour and
denial of native and Indigenous rights; private control and exploita-
tion of land and natural resources with state backing (for example,
the Congo Free State under King Leopold II of Belgium); benefits
of natural resource exploitation in one nation accruing to another
nation; a global shift from communal to private land rights14.
Developed countries’ resource consumption is outsourced to less
wealthy nations and regions15.
Conflicts often arise around the extraction of resources by com-
panies or others without legitimate user-rights to the resource (for
example, illegal logging in community forests); or when user-rights
are granted by corrupt governments (for example, access to water
already used by communities); or through political processes that
fail to respect free prior informed consent (for example, oil drilling
in concessions in indigenous territories in Peru16,17). In other cases
of conflict, traditional natural resource users are excluded from the
land, often in the name of conservation in national parks or marine
protected areas that restrict fishing activities (for example, evic-
tions of indigenous Sengwer from their traditional forest lands in
Kenya18,19). Some conflicts surround benefit-sharing from extrac-
tive industries (for example, the Panguna mine owned by Rio Tinto
subsidiary BCL in Papua New Guinea20); in others, it is the indirect
effects of the extraction that lead to conflicts (for example, water
pollution caused by mining or oil drilling and air pollution from
factories). In some more extreme cases, extractive industries can
lead to displacement of communities: either through contamina-
tion of rivers and lands that makes an area uninhabitable (for exam-
ple, Chevron and Texaco in Ecuador and Peru21,22); or by flooding
of entire communities for the creation of hydroelectric dams (for
example, the Belo Monte dam, Pará, Brazil, and the Lower Sesan 2
dam, Strung Treng, Cambodia23,24). In addition to local or national

The level of threats faced by these defenders varies depending on factors such as the country context, economic activities, and social identity (3,11,226). Thus, tailoring personal safety and security mechanisms to the local context, profile of communities and defenders, and their context is crucial, as it can significantly impact the prevention of both non-lethal and lethal attacks on defenders, their families, and communities (7,227,228). ...

The rapid expansion of the ocean economy—including industries like oil and gas, renewable energy, fishing, aquaculture, tourism, and shipping—is placing immense pressure on marine environments and coastal communities. These developments threaten biodiversity, disrupt fisheries, and pollute marine ecosystems, often violating fundamental human rights such as the right to food, health, security, and livelihoods. Many coastal populations, including Indigenous Peoples and small-scale fishers, face displacement from areas they have long depended on. In response, individuals and communities have mobilized as ocean defenders, working to protect marine environments and human rights. However, they often encounter political marginalization, threats, violence, and even murder. Despite increased global recognition of land and freshwater defenders, ocean defenders remain largely overlooked in research, policy, and conservation efforts. The Ocean Defenders Project was launched to address this gap by increasing awareness, documenting cases, and advocating for greater support. This report compiles research and case studies from the project, exploring threats to ocean defenders, the lack of data on violence against them, and the role of allies in providing protection. Through global collaboration, the project aims to amplify the voices of ocean defenders and drive meaningful action to safeguard them and the marine environments they fight to protect.
... Bennett et al., 2016). Inclusive governance processes and protection of environmental defenders from violence and rights violations (Butt et al., 2019;Le Billon & Lujala, 2020;Scheidel et al., 2023;Tran, 2023) alleviate the vulnerability associated with civil society action seeking transformative change (Blythe et al., 2018). Governmental efforts to develop corporate due diligence policies and trade agreements conditional upon upholding the United Nations Declaration on the Rights of Indigenous Peoples and divestment campaigns targeting corporations involved in rights violations could all be entry points to increase the environmental impact of civil society initiatives. ...

Chapter 5 presents quantitative and qualitative insights on actions and instruments around five strategies to bring about transformative change. Together these strategies address direct and indirect drivers (including underlying causes) of biodiversity loss and nature’s decline (Chapter 1) with explicit attention to overcoming the specific challenges to transformative change (Chapter 4). The five strategies are: 1) conserving and regenerating places of value to nature and people; 2) driving systemic change in the sectors most responsible for biodiversity loss and nature’s decline; 3) transforming economic systems for nature and equity; 4) transforming governance systems to be inclusive, accountable and adaptive; and 5) shifting societal views and values to recognize and prioritize the fundamental interconnections between humans and nature. An assessment of the literature that includes works examining deliberate transformative change for a just2 and sustainable world suggests that some of these strategies are have been studied more and literature aligns among contexts while others have more diverse or limited evidence behind them. Actions associated with the strategies serve as entry points for a set of intertwined, diverse and emergent pathways informed by theories of transformative change (Chapter 3) and guided by diverse visions for achieving the 2050 Vision for Biodiversity and other global sustainability goals (Chapter 2).

... While industrial-scale mining and energy projects can offer remote communities socioeconomic and environmental benefits (better access to energy, income, services, and education) [e.g., [7,8]], research highlights significant negative impacts, including loss and degradation of ancestral lands and waters, conflicts and displacements, risks to health and life, impacts on culturally significant sites and activities, and unfair benefit-sharing [e.g., [9,10,11]] Ongoing energy transitions are deeply tied to colonial histories, when hydroelectric dams and oil exploration were developed in a way that disrupted Indigenous ways of life and marginalised Indigenous leadership in resource governance. Many Indigenous communities continue to be excluded from decision-making, and are subjected to violence, discrimination, criminalisation and ignorance [12,13]. Calls for justice emphasize the need to rectify colonial legacies and avoid perpetuating marginalization by recognising and respecting Indigenous sovereignty in infrastructure planning and resource management [14,15]. ...

Governance and decision-making that uphold the rights, interests, knowledges, and values of Indigenous peoples and land-connected communities are increasingly recognised as critical components of a just energy transition. Despite the unprecedented inclusion of Indigenous peoples in resource governance, it is unclear how community consultation and consent can effectively support Indigenous-centred decision-making. In this paper, we provide an integrative and case review of community experiences with consultation and consent across the Arctic and sub-Arctic region which along with other ‘resource geographies’ are increasingly affected by transition minerals mining and renewable energy infrastructure. Key themes identified in the review include: (1) limitations of state and company-led community consultation and consent; (2) practices of Indigenous-centred (Indigenous-led, Indigenous-benefiting and Indigenous-informed) decision-making; and (3) barriers to Indigenous-centred decision-making. Focusing on the circumpolar north, this paper contributes to broadening the discussion on just energy transitions for Indigenous peoples. Implications for scholarship and practice are discussed, reflecting community consultation and consent in the current rush to supply minerals and infrastructure for the global energy transition.

In Southeast Asia, environmental and human rights activists resisting authoritarian rule and extractive development face harassment, intimidation and lethal danger in dramatically different ways. In the Philippines, this atmosphere of violence intensified under former President Rodrigo Duterte, a political ‘strongman’ whose militarized masculinity deepened the repression of left‐wing women activists and other political opposition across the country. Despite macro‐level studies examining the trends and patterns behind the surge in activist harassment, the micro‐politics of Duterte's misogynistic and revanchist violence towards women activists has received insufficient attention. Drawing on feminist political ecology, this article explores how and why women activists on Palawan Island and elsewhere in the Philippines continued their advocacy work as they navigated intersectional spaces of violent misogyny and government repression. It shows how women activists in Palawan drew upon hope to persevere in their work amidst the violent atmospheres stoked by authoritarian masculinity. The article describes how the temporalities of intersectional gendered violence variously impacted the lives of women activists as they defended the environment and human rights on the island, while the country's highest office legitimated toxic chauvinism as a mode of governance.

Purpose In response to the worsening environmental crisis, there have been multiple calls for sustainable supply chain management (SSCM) scholars and practitioners to adopt a “business-not-as-usual” approach based on justice, fairness, equity and sustainability. We add to this literature by proposing environmental justice (EJ) as a key concept for the theory and practice of SSCM. Design/methodology/approach This conceptual article builds SSCM theory on EJ and contributes to supply chain justice research and practice by introducing the concept of the “environmentally just supply chain” and presenting pathways for operationalizing it in practice. Findings Three pathways are proposed to leverage transformative SSCM to create environmentally just supply chains: human rights due diligence, resilience thinking and coproduction of environmentally just supply chains. Practical implications The three pathways can be used by actors within a supply chain to create environmentally just supply chains. Originality/value This article extends transformative, non-instrumental perspectives on environmental sustainability within SSCM scholarship to provide insights into how supply chains can be transformed through EJ. Not only does the article show the relevance of EJ for SSCM theory and practice, but it elaborates pathways for moving from harm reduction to transformative sustainability actions.

Halting deforestation is essential to address climate change and biodiversity loss. However, in highly forested, low-income countries like Liberia, “zero deforestation” commitments (ZDCs) adopted by companies may restrict agricultural expansion that has been promoted in national strategies to alleviate poverty. In such situations, examining contrasting perspectives among stakeholders is important to inform ZDCs’ implementation. Here, we applied Critical Systems Heuristics in 94 interviews to explore stakeholders’ perspectives on, and thereby develop a systematic understanding of, ZDCs in Liberia’s concession-based palm oil sector. We found that regulatory, institutional, and political factors that were needed to support commitments’ implementation were missing. Concessions had initially been allocated without communities’ consent being adequately obtained, and oil palm expansion had subsequently been stalled by zero deforestation. This produced a situation where communities that lost farmland to oil palm were reluctant to allow further expansion, while communities in forest areas were frustrated by a lack of promised oil palm expansion. Consequently, although limited oil palm expansion suggests ZDCs were effective after they were adopted, this was perceived to have come at the expense of anticipated improvements in community welfare, with community members in highly forested areas feeling deprived of development. We argue that neither the complete development of Liberia’s oil palm concessions nor limited development with zero deforestation will necessarily improve communities’ welfare without reforming the concession system to promote community-led, deforestation-free agricultural development. This requires public governance reforms, novel mechanisms for agricultural investment, and the localisation of international standards to facilitate zero deforestation in smallholder agriculture.

The US has alarmingly high, and rising, gun violence and fatality rates. While it is generally believed that supply side policy is critical in addressing the problem, legislation has been relatively ineffective, for example the Gun Violence Prevention and Community Safety Act of 2020. Previous literature has identified hotspots and proximate determinants, particularly urban locations. Effective supply side policy would require application of optimal transport methods. We apply novel and current generation structural models to identify the spatial network for supply of guns and propagation of violence risks. This provides clean quantification of spatial supply chains and associated costs of transport between nodes, which are necessary for mitigation using optimal transport and logistics network management methods.

Environmental and resource governance models emphasize the importance of local community and civil society participation to achieve social equity and environmental sustainability goals. Yet authoritarian political formations often undermine such participation through violent repression of dissent. This article seeks to advance understandings of violence against environmental and community activists challenging authoritarian forms of environmental and resource governance through eco-populist struggles. Authoritarianism and populism entertain complex relationships, including authoritarian practices toward and within eco-populist movements. Examining a major agrarian conflict and the killing of a prominent Indigenous leader in Honduras, we point to the frequent occurrence of deadly repression within societies experiencing high levels of inequalities, historical marginalization of Indigenous and peasant communities, a liberalization of foreign and private investments in land-based sectors, and recent reversals in partial democratization processes taking place within a broader context of high homicidal violence and impunity rates. We conclude with a discussion of the implications of deadly repression on environmental and land defenders. Key words: authoritarianism, environmental defenders, Honduras, populism, repression.

Despite continuing uncertainty over the precise legal status of the putative human right(s) of access to water and sanitation in international law, and also within the domestic legal framework of many national jurisdictions, the elaboration continues apace of a rich montage of water services standard by diverse cast of formal and informal global, regional, State and transactional actors. in addition to the emerging standards regarding the physical safety and adequacy of water supplied for domestic purposes, notably including WHO Guidelines for Drinking Water Quality, standards are also being adopted by bodies such as the International Organisation for Standardardisation (ISO), which set down more general service quality guidelines for utilities providing domestic water and sanitation services. …

State-controlled protected areas (PAs) have dominated conservation strategies globally, yet their performance relative to other governance regimes is rarely assessed comprehensively. Furthermore, performance indicators of forest PAs are typically restricted to deforestation, although the extent of forest degradation is greater. We address these shortfalls through an empirical impact evaluation of state PAs, Indigenous Territories (ITs), and civil society and private Conservation Concessions (CCs) on deforestation and degradation throughout the Peruvian Amazon. We integrated remote-sensing data with environmental and socio-economic datasets, and used propensity-score matching to assess: (i) how deforestation and degradation varied across governance regimes between 2006–2011; (ii) their proximate drivers; and (iii) whether state PAs, CCs and ITs avoided deforestation and degradation compared with logging and mining concessions, and the unprotected landscape. CCs, state PAs, and ITs all avoided deforestation and degradation compared to analogous areas in the unprotected landscape. CCs and ITs were on average more effective in this respect than state PAs, showing that local governance can be equally or more effective than centralized state regimes. However, there were no consistent differences between conservation governance regimes when matched to logging and mining concessions. Future impact assessments would therefore benefit from further disentangling governance regimes across unprotected land.

During the development of green criminology, little attention has been paid to how Indigenous/Native Peoples (INP) are victimized by green crime and how they employ environmental activism to resist externally imposed ecological destruction. In the past decade, news services and environmental interest groups have reported on the killing of INP environmental activists who have resisted ecological destruction across the world. Here, we begin to develop a green criminological view of INP victimization and resistance to ecological destruction within the context of the global capitalist treadmill of production, while drawing upon concepts of colonization, imperialism, genocide and ecocide. Our analysis suggests that in the contemporary capitalist world system, expansion of the treadmill of production's ecological withdrawal process (i.e. the withdrawal of raw materials used in production) not only accelerates ecological disorganization in developing/underdeveloped nations, but may be harmful in nations where INP are dependent on access to nature for survival.
