This paper examines Tanzania's role in illicit miombo timber flows, associated risks and policy responses, highlighting gaps and opportunities for effective action.

Overview

Illicit timber flows linked to Tanzania are a security, governance and economic threat that fuel organised crime, weaken state revenue and place the miombo woodlands under mounting pressure.

This paper examines Tanzania's role as both a source and transit hub for high-value miombo hardwoods moving through regional and global supply chains. It finds that corruption, document fraud, weak traceability at the point of harvest and inconsistent cross-border controls allow illegally sourced timber to be laundered into legitimate trade. These flows can converge with wildlife trafficking, minerals crime and, in some contexts, arms, drugs and conflict financing.

Tanzania has strengthened its response through tougher economic-crime and anti-money laundering provisions, alongside the Timber Tracker system for domestic transport monitoring. Yet enforcement often remains focused on low-level harvesters and drivers rather than the transnational networks, facilitators and financial flows that enable large-scale timber crime. The paper argues that treating illicit timber as a serious organised economic crime is essential to protecting forests, public revenues and regional security.

Key Recommendations

  • Follow the money: Conduct joint, intelligence-led financial investigations into timber cases to identify illicit traders, facilitators, assets and illicit proceeds.
  • Close legal loopholes: Remove the Forest Act's compounding provision, which can prevent cases from progressing into full criminal and financial investigations.
  • Improve traceability: Strengthen oversight at harvesting sites and expand the use of digital tracking, species identification, geospatial tools and other monitoring technology.
  • Target cross-border risks: Deepen information sharing and harmonise customs and forestry controls with neighbouring states and Zanzibar.
  • Strengthen community incentives: Simplify and decentralise permits for small-scale harvesters and expand community-based forest management so local communities benefit from legal, sustainable forestry.
  • Increase market accountability: Require stronger import due diligence in destination markets and publish species-specific trade data to expose irregularities and trade discrepancies.

The paper highlights that effective action against illicit timber trade in Tanzania can deliver both conservation gains and wider defence and security benefits by disrupting the criminal networks that profit from natural-resource exploitation.

Introduction

The miombo woodlands are a vast forest ecosystem spanning nearly 2 million km² across Southern Africa, including parts of Angola, the Democratic Republic of Congo (DRC), Malawi, Mozambique, Tanzania, Zambia and Zimbabwe. They are rich in biodiversity, housing species including iconic megafauna and about 8,500 plants, of which 54% are endemic. The woodlands support the livelihoods of an estimated 100 million rural and 50 million urban people, supplying wood fuel and charcoal, food, medicine and grazing resources. By storing significant quantities of above-ground biomass, they also play an important role in carbon sequestration, making their protection and restoration essential for meeting global emission reduction targets.

Within the woodlands, miombo hardwoods are increasingly occupying a significant role in global timber markets, particularly in China, where a surge in demand for 'low end class' African rosewood species to supply Chinese hongmu furniture markets1  has led to significant pressure for illegal logging in large swathes of miombo woodlands. This has resulted in recent global interventions to enhance the protections and trade controls for relevant miombo hardwoods under Appendix II of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).2

As an important source and transit country for international flows of miombo hardwoods, Tanzania has the potential to benefit from sustainable trade, which offers opportunities for economic growth and job creation. However, criminal infiltration and exploitation of the timber sector threaten to undermine this potential in various ways: by driving unsustainable extraction; by diverting financial benefits away from communities and towards corrupt facilitators, foreign beneficiaries and threat actors; and by intersecting with other illicit activities. Despite this, there has been limited systematic research into the nature of the threat which illicit timber flows pose to Tanzania. Existing studies are either outdated or focus on other miombo hardwood producer countries.

This paper fills that gap by reviewing existing evidence of Tanzania's role in regional and international illicit timber flows and interrelated governance and security risks, as well as Tanzania's progress to date in countering the threat. The paper identifies areas that require further research and policy attention.

The first section explores Tanzania's position in international flows of miombo hardwoods. The second section examines risks of corruption and fraud, illicit finance and other converging criminal economies linked to illicit timber flows in Tanzania, such as illegal wildlife trade, minerals crime, arms and drug trafficking and labour abuses. The third section considers Tanzania's legal and enforcement response to timber offences to date and identifies opportunities for a strengthened response. The conclusion offers policy recommendations for Tanzanian policymakers, management authorities and law enforcement and justice agencies, as well as international trade and development partners.

Timber Flows In and Out of Tanzania

Tanzania as a Source Country of Hardwood

The miombo woodlands cover much of Tanzania's central, western and southern plateau, comprising about 90% of its forested area, or 44.6 million hectares (see Figure 1). When timber industry revenues and ecosystem services are considered (such as carbon storage, water regulation, soil quality and pollination), the country's forests are estimated to comprise 20% of Tanzania's GDP, underpinning other key sectors such as energy, agriculture and tourism.
