Africa: Documenting Killings and Disappearances of Land and Environmental Defenders

Africa: Documenting Killings and Disappearances of Land and Environmental Defenders


Every year, Global Witness works with partners to gather evidence, verify and document every time a land and environmental defender is killed or disappeared. Our methodology follows robust criteria, yet undocumented cases pose challenges when it comes to analysing data

Global Witness documents killings and long-term disappearances of land and environmental defenders globally. In partnership with over 30 local, national and regional organisations in more than 20 countries, we produce an annual report containing these figures, and we have done so since 2012.

Our methodology involves a year-long process of cross-referencing data from different sources to ensure its credibility. Over 2,200 killings or long-term disappearances of defenders appear in our database since 2012 – with 146 cases documented in 2024.

Every year, we maintain a database to keep a record of these crimes and create a comprehensive global picture of the systematic violence defenders face.

The data provides a snapshot of the underlying drivers behind reprisals and indicates how some defenders and their communities face increased risks. Exposing these trends is the first of many steps to ensure that defenders and their communities are protected and can exercise their rights without fearing for their lives.

Classifying defenders’ cases

Most of the cases recorded in our database are killings – including assassinations by illicit actors, state murder and death in detention.

Our database also includes disappearances of defenders, where the individual has been missing for six months or more.

All reports prior to 2025 have combined killings and long-term disappearances into one single headline figure. For greater clarity, our latest report indicates a distinction between these two types of attack, and our reports will continue to make this distinction in future.

Cases from prior years or those already included in our database are not continuously monitored. Where we receive updated information on an attack, we may retrospectively include or remove cases.

We document the killing or disappearance of a defender when there is a reasonable and suspected link to an individual’s activism or where the individual played a role in defence of the land or the environment.

As well as individuals directly involved in activism, we also document tangential violence against families, community members or others caught up in attacks.

Our definition covers a broad range of people and encompasses different types of land and environmental leadership. Crucially, this involves people who work in any capacity to protect rights linked to the exploitation of land or the environment.

How we define land and environmental defenders

Land and environmental defenders are a specific type of human rights defender – individuals or groups of people who act to promote, protect or strive for the realisation of human rights through peaceful action.

Their role as human rights protectors is recognised by the UN Declaration on Human Rights Defenders, principles also enshrined in other legally binding international instruments. This includes those working to protect human rights relating to the environment, including water, air, land, flora and fauna.

We define defenders as people who take peaceful action against the unjust, discriminatory, corrupt or damaging exploitation of natural resources or the environment.

Land and environmental struggles take different forms and are shaped by local contexts. For example, in every region of the world, communities strive against systematic land dispossession and environmental destruction from extractive industries.

For some the threat to territories is intimately connected to the degeneration of their sovereignty, culture, livelihoods and homes. Others are caught in wider conflicts which exacerbate land, environmental and climate injustices.

Defenders often live in communities whose land, health and livelihoods are threatened by the operations of mining, logging, agribusiness or other industries.

Some defend our biodiverse environment, while others support such efforts through their roles as lawyers, politicians, park rangers, journalists, or members of campaigns or civil society organisations.

Others are holders of traditional or Indigenous knowledge, working as Indigenous guards or community knowledge keepers.

Identifying and documenting cases

We learn of killings and disappearances through reliable sources of online reporting, tip-offs and wider documentation efforts from civil society organisations.

We set up search engine alerts using keywords and conduct other searches online to identify relevant cases. We also share information with international and national organisations who report on attacks against human rights defenders.

We then research each case to assess whether the person killed or disappeared was a land and environmental defender, according to our definition.

Desk-based research has its limitations. Many attacks on land and environmental defenders receive little or no media attention, due to the remote location of attacks, stigmatisation by investigating authorities, or widespread government repression of the media.

In most instances, we supplement identified cases with additional research. This includes working closely to share information with trusted civil society organisations and communities who have gathered evidence through their own investigations.

Verifying information

We work closely with in-country partners to verify whether there is a reasonable and suspected link between the killing or disappearance and the person’s activism.

Testimony from families, communities and organisations working with targeted defenders often provides key information. Sometimes we review official documentation, including police reports or legal documents. This information is documented by Global Witness and not made public.

Navigating toxic narratives

Year after year, we are confronted with cases where the very nature of what it means to be a land and environmental defender is questioned.

Often governments, corporations and media outlets propagate a narrow view of land and environmental activism, excluding individuals and communities whose role defending land or environmental rights is less recognisable.

Across the world, defenders and their communities are often labelled as “criminals”, “agitators” or “communists”. These toxic terms are sometimes employed by the institutions and authorities that claim to uphold people’s rights.

Media can often repeat damaging narratives or even simply ignore reporting on these cases, making it difficult to verify whether an attack could be linked to a persons’ activism.

In these situations, we work closely with local organisations to clarify the contexts in which defenders work, and the patterns of stigmatisation they face, and gather more evidence of the role they played in environmental and land rights protection.

We also work alongside other organisations gathering national, regional and international reprisal-related data. This includes official UN sources of data collection as well as civil society initiatives.

Every data collection project has its own definitions and methodologies, which create challenges in collating this data into a global dataset on attacks against defenders. Some existing datasets overlap with ours, but often do not fully coincide.

For every case documented, we research and evaluate whether it fits our definition of a land and environmental defender.

Often, public reporting on attacks is circumstantial or lacks information. In some cases, attacks go unreported, particularly in rural areas and in certain countries.

In these cases, countries with restricted civic space – where civil society organisations, NGOs and other groups that monitor the work of defenders are less present, for example – are not able to fill the reporting gap.

This is further exacerbated by repression of the media, authoritarian governments and active political conflicts. Documenting massacres or reprisals in active conflict zones, areas under occupation or where organised crime groups have social or territorial control is also challenging.

These contextual challenges mean that our data is likely to underreport killings and disappearances in certain countries and regions of the world – particularly in areas of Asia, Africa and the Middle East.

Spotlighting our criteria

To meet our criteria, a case must be supported by the following available information:

  • Credible sources of information. This can include online publications, official documentation on a case or collating information from families, colleagues and civil society organisations linked to a case.
  • Details about the type of act and method of violence, including the date and location.
  • Name and biographical information about the victim.
  • Clear, proximate and documented connections to the protection and defence of environmental and land rights. This includes evaluating the various roles of defenders play and the wider contexts and underlying conflicts that affect them.

Analysing the data

We seek to understand the most dangerous repercussions defenders face in the context of the territorial and environmental disputes taking place in their countries.

We also look to understand the characteristics of defenders and their communities – who they are as people and whether some face greater, more targeted risks.

Focusing on the most serious harms (killings and disappearances) enables us to confidently verify the threats defenders face and allows us to analyse geographical trends at regional, country and local level – though with recognised limitations.

We record whether a defender belongs to a marginalised group – Indigenous Peoples, Afro-descendants or rural communities – or if they act as a defender in their role as lawyers, journalists or members of civil society organisations. This enables us to understand more about the characteristics of defenders working to protect land and the environment.
