Researchers identify global mega-trends that impact forest health – and the communities who rely on them

Forests are essential to our attempts to tackle climate change, reduce biodiversity loss and live more sustainably — and yet they are being significantly impacted by everything from major infrastructure projects to expanding middle classes, potentially undermining efforts to tackle the current environmental emergency.

In an important step towards better understanding the dynamics which affect forest health, a group of researchers and practitioners have used advanced analytical tools to identify five major trends currently impacting forests on a global scale.

Breaking from previous research which has tended to focus on local drivers on forest health, the study paints a complex picture in which consumption in North America and Europe is driving deforestation, land-use change and environmental degradation in the Amazon, the Congo Basin and Indonesia – all areas which are home to Indigenous Peoples and local communities. Meanwhile smoke from forest fires can impact the health of populations in neighbouring countries and even the weather patterns of other continents.

The study, and the so-called “horizon scanning” approach it uses, offers a better chance of understanding the diverse and often global pressures being exerted on the world’s last remaining great forests, as well as developing approaches which can support sustainable forest livelihoods at a local level, helping to shape a more sustainable global relationship with nature.

" the requirement for functioning governance and decision-making systems only increases with increased demand/pressure on resources. Local institutions need to be recognised and given space in national and regional planning and policy making"

- Margareta Nilsson, Head of Programmes, the Tenure Facility

Within this, the need to secure tenure for forest-dwelling communities and ensure responsible management of forestlands have been identified as crucial steps, according to Margareta Nilsson, who co-authored the report, and is the Tenure Facility’s Head of Programmes.

“One conclusion from the study is how the requirement for functioning governance and decision-making systems only increases with increased demand/pressure on resources. Local institutions need to be recognised and given space in national and regional planning and policy making”, Nilsson said.

“Having your rights recognized is always the better starting-point when global trends are impacting your lands and resources.”

Within the research, five key mega-trends were identified in the study as being especially impactful on forest health:

  • Major forest disturbances such as wildfires, floods and tree mortality, often linked to human-influenced climate change. Forest destruction is not only harmful for biodiversity, it can also increase the risks of zoonotic disease transmission.
  • Migration and demographic shifts, which are seeing large numbers of working age men moving to cities, effectively “feminising” the rural landscape.
  • Emerging middle classes in lower income countries are pushing up demand for forest commodities — including palm oil and meat — placing greater pressure on forests, whilst unhealthy processed diets are endangering both people and the environment
  • The rise of technology is creating opportunities for forest-dwelling communities, offering better communications and better data-collecting potential. However, they can also be used to drive illegal logging and other activities.
  • Large-scale infrastructure development, including the construction of millions of kilometres of road in the coming decades and the emergence of mining and hydroelectric projects, will speed forest loss, displace forest-dwelling communities, and drive conflict.

Researchers hope that further study of these major trends could help lead to a better understanding of the causality behind forest destruction and biodiversity loss, which could in turn inform more nuanced policymaking to ensure both that forests are conserved, rights respected and that the livelihoods that depend upon them are protected.

La terre sous leurs pieds : le cheminement des communautés Bagyeli vers la reconnaissance de leurs droits fonciers

Dans le département de l’Océan, au sud du Cameroun, les routes serpentent entre des forêts denses, de longues pistes de latérite rouge et des plantations industrielles qui semblent s’étendre un peu plus chaque année.

The land beneath their feet: Bagyeli communities’ journey towards recognition and security of their land and forest rights

In the Ocean Department of southern Cameroon, roads wind through dense forests, long stretches of red laterite tracks, major development projects — including mining and agro-industry — and industrial plantations that seem to expand a little further each year, gradually reducing the living space available to communities.

Pourquoi les droits fonciers ne peuvent pas attendre la paix

Et si attendre la paix était l’un des plus grands obstacles à la sécurisation des droits fonciers ? Pendant des décennies, la gouvernance foncière a été largement considérée comme un élément de la reconstruction post-conflit. L’hypothèse était simple : le conflit prend fin, les institutions se redressent, les populations rentrent chez elles, et ce n’est qu’alors que les droits fonciers peuvent être rétablis. Dans de nombreuses régions du monde, cependant, cette séquence ne correspond pas à la réalité. Les conflits sont souvent prolongés, les institutions peuvent être affaiblies ou inexistantes, et les registres fonciers officiels ont parfois disparu. Pourtant, les communautés continuent de cultiver leurs terres, de gérer les forêts, de résoudre les différends et de défendre leurs territoires en s’appuyant sur les systèmes de gouvernance qui restent à leur disposition.

Why land rights can't wait for peace

What if waiting for peace is one of the biggest obstacles to securing land rights? For decades, land governance has largely been treated as part of post-conflict recovery. The assumption has been straightforward: conflict ends, institutions recover, people return home, and only then can land rights be restored. In many parts of the world, however, that sequence does not reflect reality. Conflict is often prolonged, institutions may be weakened or absent, and official land records may have disappeared. Yet communities continue farming, managing forests, resolving disputes, and defending their territories using the governance systems still available to them.

"We are the middle, the beginning and the middle." : Quilombola women in land rights and climate action

Long before a land title is granted or a policy is signed, movements are built. They are built by women and men organising communities, defending territories, passing on ancestral knowledge, protecting culture, and ensuring generations of struggle are never forgotten. Between 10 and 14 June 2026, the III Meeting of CONAQ's Quilombola Women's Collective brought hundreds of these leaders together from across Brazil, alongside representatives from Latin America and Africa. Over five days, they celebrated victories, confronted urgent challenges and strengthened a movement that continues to shape Brazil's conversations on land rights, climate justice, gender equality and historical reparation.

Seeding land rights in northern Republic of Congo

The road into the Sangha and Likouala departments in northern Republic of Congo passes through thick forest. Yet asphalt gives way to red soil where logging trucks pass day and night, carrying off trees that stood firm for centuries before concession paperwork tried to redefine who owns the land. These forests hold more than timber—they cradle rivers, fertile soils, unique species, and carbon stock.
