Tanzania’s mining GDP growth from 197,832.14 TZS million in Q4 2008 to 2,317,959 TZS million in Q4 2024 (approximately 0.923 billion USD at 2,510 TZS/USD) represents a remarkable 1,072% increase in nominal terms, averaging an annual growth rate of about 16.7% over the 16-year period. This growth, driven by gold, tanzanite, coal, and emerging critical minerals like lithium and graphite, has significantly shaped Tanzania’s economic development through increased GDP contribution, export earnings, tax revenue, job creation, and infrastructure development, while also presenting challenges that influence long-term sustainability.

Increased Contribution to National GDP

The mining sector’s growth has elevated its share of Tanzania’s GDP from approximately 3.5% in 2008 to 10.1% in 2024, surpassing the government’s 2026 target of 10%. This shift has transformed mining into a cornerstone of Tanzania’s economy, reducing reliance on agriculture (which contributes ~25% to GDP) and tourism. The sector’s 2,317,959 TZS million contribution in Q4 2024 reflects a robust extractive industry, with gold alone accounting for a significant portion due to Tanzania’s position as Africa’s fourth-largest gold producer (~40–47 metric tons annually). This has:

• Diversified the Economy: Mining’s increased GDP share has balanced Tanzania’s economic structure, making it less vulnerable to agricultural volatility caused by weather or global commodity price fluctuations.
• Boosted Economic Growth: Tanzania’s overall GDP growth averaged 6–7% annually in recent years, with mining’s contribution helping sustain this trajectory. The sector’s growth has supported Tanzania’s ambition to become a middle-income economy, achieved in 2020 with a GNI per capita of USD 1,080 (World Bank).

Enhanced Export Earnings and Foreign Exchange

The mining sector’s expansion has significantly increased Tanzania’s export earnings, strengthening its balance of payments and foreign exchange reserves. Key figures include:

• Mineral Exports: In 2020, mineral exports reached USD 3.6 billion, with gold dominating. By 2024, total exports (including minerals) hit USD 16.1 billion, a 15.1% year-on-year increase, with mining playing a pivotal role.
• Specific Commodities: Coal exports surged from USD 23.2 million to USD 228.6 million year-on-year, and diamond exports grew from USD 9.6 million to USD 66.9 million, reflecting diversified mineral contributions.
• Impact: These earnings have stabilized the Tanzanian shilling, funded imports, and supported external debt servicing, contributing to macroeconomic stability. For context, Tanzania’s foreign exchange reserves were USD 5.3 billion in 2023, partly bolstered by mining exports.

Increased Tax Revenue and Fiscal Capacity

The mining sector’s growth has significantly boosted government revenue, enabling public investment in infrastructure and social services:

• Tax Revenue: Mining tax revenue rose by 20.7% to TZS 753.82 billion (approx. USD 0.3 billion) in 2023/2024, with TZS 312.75 billion collected by October 2024 toward a TZS 1 trillion target for 2024/2025.
• Policy Reforms: Regulatory changes, including local content policies and gemstone auctions, have improved revenue collection. The 2017 Mining Act amendments, increasing royalties and government stakes in mining projects, were instrumental.
• Impact: Increased fiscal capacity has funded infrastructure projects like roads, ports, and the East Africa Crude Oil Pipeline, as well as social programs in education and healthcare, enhancing living standards. For example, Tanzania’s Human Development Index (HDI) improved from 0.488 in 2008 to 0.549 in 2022, partly due to mining-driven economic growth.

Job Creation and Social Impact

The mining sector’s expansion has generated significant employment, contributing to poverty reduction and economic inclusivity:

• Employment: The sector employed 310,000 Tanzanians in 2020, with 19,356 new jobs created by March 2024 (97% for Tanzanians). This includes direct jobs in mining and indirect jobs in related industries like logistics and processing.
• Local Empowerment: Policies mandating local hiring and training have ensured that economic benefits reach Tanzanian communities, particularly in mining regions like Geita and Shinyanga.
• Impact: Job creation has reduced unemployment (estimated at 2.6% in 2023) and supported rural economies, where mining is a major employer. However, challenges like artisanal mining conflicts and environmental concerns persist.

Infrastructure and Investment Attraction

The mining sector’s growth has spurred infrastructure development and attracted foreign direct investment (FDI):

• Infrastructure: Mining revenue has supported projects like the USD 30 billion Likong’o-Mchinga LNG plant and the Standard Gauge Railway, improving connectivity and economic efficiency.
• FDI: Investments like USD 3.15 billion from Australian companies for rare earths and graphite, and Tesla’s contract for anode active material, highlight Tanzania’s appeal in the global critical minerals market.
• Impact: These developments have enhanced Tanzania’s industrial capacity and positioned it as a key player in the energy transition, with minerals like lithium and graphite critical for batteries and renewable energy technologies.

Challenges and Risks to Economic Development

While the mining sector’s growth has been transformative, it poses challenges that could affect long-term economic development:

• Resource Dependency: The 10.1% GDP share from mining risks over-reliance, exposing Tanzania to global commodity price volatility (e.g., gold price fluctuations).
• Environmental Concerns: Mining activities, particularly in ecologically sensitive areas, have raised concerns about deforestation and water pollution, potentially undermining sustainable development.
• Inequitable Benefits: Despite job creation, wealth distribution remains uneven, with some mining communities still facing poverty (Tanzania’s poverty rate was 26.4% in 2020).
• Governance Risks: Past disputes with mining companies (e.g., Acacia Mining in 2017) highlight the need for consistent and transparent policies to maintain investor confidence.

Position in Africa and East Africa

Tanzania’s mining GDP of 0.923 billion USD in Q4 2024 ranks it among Africa’s top five mining economies, behind South Africa (11.5 billion USD), Egypt (5.1 billion USD), and Guinea (4.9 billion USD, 2023 data), but ahead of Nigeria (0.625 billion USD) and Ghana (0.446 billion USD). In East Africa, Tanzania leads, surpassing Mozambique (0.545 billion USD), Kenya (0.189 billion USD), Uganda (0.226 billion USD), and Rwanda (0.037 billion USD). This leadership enhances Tanzania’s regional influence and supports economic integration through projects like the East Africa Crude Oil Pipeline.

Conclusion

The growth of Tanzania’s mining GDP from 197,832.14 TZS million in 2008 to 2,317,959 TZS million in 2024 has been a catalyst for economic development, increasing GDP share to 10.1%, boosting exports to USD 16.1 billion (2024), generating TZS 753.82 billion in tax revenue, and creating 310,000+ jobs. These outcomes have supported macroeconomic stability, infrastructure development, and poverty reduction, positioning Tanzania as a middle-income economy and East Africa’s mining leader. However, challenges like resource dependency and environmental impacts require careful management to ensure sustainable development. By leveraging its mineral wealth and continuing policy reforms, Tanzania can further enhance its economic trajectory.
