A Data-Driven Assessment Towards the Tanzania Blue Economy 2050 Vision — diagnosing structural gaps and charting a credible USD 40–50 billion pathway for the nation's ocean economy.
From USD 9.6 billion today to USD 40–50 billion by 2050: what it will take, and why the gaps are closeable.
Tanzania's Blue Economy — encompassing fisheries, coastal tourism, maritime transport, aquaculture, seaweed farming, and emerging offshore sectors — is one of the country's most consequential sectors for long-term economic transformation. With over 1,424 kilometres of Indian Ocean coastline, the globally renowned archipelagos of Zanzibar and Pemba, and the vast freshwater systems of Lakes Victoria, Tanganyika, and Nyasa, Tanzania possesses natural endowments that few nations in sub-Saharan Africa can rival.
By 2025, Tanzania's blue economy contributes an estimated USD 9.6–10.5 billion annually — approximately 11–12% of national GDP — and supports between 4.5 and 6 million direct and indirect jobs. Yet this performance represents only a fraction of the sector's structural potential. UNECA's Blue Economy Valuation Toolkit estimated combined blue economy market and ecosystem service values at over USD 111 billion, illustrating the immense gap between current and achievable output.
Tanzania's blue economy gap is not primarily a resource gap. The natural endowments are extraordinary. The gap is institutional, informational, financial, and human — and all of these gaps are closeable with the right policy framework and sustained investment.
| Indicator | 2025 Baseline | 2035 Target | 2050 Vision |
|---|---|---|---|
| Blue Economy GDP Contribution | USD 9.6–10.5 bn | USD 18–22 bn | USD 40–50 bn |
| Share of National GDP | 11–12% | 15–17% | 20–25% |

Tanzania's unparalleled blue economy endowments and the structural imperative for a long-horizon 2050 Vision.
Tanzania is endowed with one of the most diverse and extensive blue economy resource bases in sub-Saharan Africa. Its 1,424-kilometre Indian Ocean coastline spans five mainland regions — Tanga, Pwani, Dar es Salaam, Lindi, and Mtwara — and the semi-autonomous islands of Zanzibar (Unguja) and Pemba, whose combined terrestrial area of approximately 2,650 km² is dwarfed by the surrounding marine resource zones that underpin their economies.
Tanzania's Exclusive Economic Zone (EEZ) of approximately 223,000 km² encompasses globally significant coral reef systems, seagrass meadows, mangrove forests, and deep-sea mineral deposits. Inland, Lakes Victoria (the world's second-largest freshwater lake by surface area), Tanganyika (the world's second deepest lake), and Nyasa together constitute a freshwater dimension of the blue economy of equivalent strategic importance for food security and livelihoods.
The imperative for a long-horizon vision in blue economy planning is not merely aspirational — it is structurally necessary for three reasons:
This report aligns with AU Agenda 2063 ('The Africa We Want'), the UN Sustainable Development Goal 14 (Life Below Water), Tanzania's Development Vision 2050, and the Global Biodiversity Framework (Kunming-Montreal, 2022).
The global ocean economy, Tanzania's policy architecture, and the evidence base underpinning this assessment.
The global ocean economy generates approximately USD 1.5 trillion annually in market goods and services, with the OECD projecting this figure to more than double to USD 3 trillion by 2030 under sustainable management scenarios. Emerging blue economy sectors — offshore wind energy, marine biotechnology, desalination, blue carbon markets, and deep-sea aquaculture — are among the fastest-growing industries globally. The IEA estimates that offshore wind capacity could expand 15-fold by 2040, representing a USD 1 trillion investment opportunity.
| Policy Instrument | Year | Jurisdiction | Key Mandate |
|---|---|---|---|
| Zanzibar Blue Economy Policy & Implementation Strategy | 2020 | Zanzibar | First dedicated subnational blue economy policy in Tanzania; institutional roles and sustainability commitments |
| National Blue Economy Policy | 2024 | Union | Tanzania's first Union-level framework coordinating Mainland and Zanzibar; priority investment areas |
| Third Five-Year Development Plan (FYDP III) | 2021–2026 | Union | Blue economy as structural transformation priority within national development framework |
| National Climate Change Strategy 2050 | 2022 | Union | Integrates coastal and marine climate adaptation as national priority; links to blue economy sustainability |
| AU Agenda 2063 & SDG 14 | Ongoing | International | External accountability framework for Tanzania's ocean governance commitments |
UNECA's authoritative 2020 Blue Economy Valuation estimated direct market contributions at USD 7.2–7.74 billion and ecosystem service values at an additional USD 104.24 billion — a combined figure of over USD 111 billion that illustrates the extraordinary gap between what the sector currently produces and what its ecological foundations are worth.
Research design, data sources, and the three scenarios underpinning the 2050 Vision projections.
This study employs a desk-based, data-driven research design. The analytical objective — mapping current-state gaps against long-horizon potential — is best served by a systematic secondary data synthesis approach, complemented by scenario modelling for 2050 projections. Primary fieldwork was beyond the scope of this study but is identified as a priority for the next phase of TICGL research.
Three economic scenarios are used to generate the 2050 Vision projections:
| Indicator | 2025 Baseline | BAU 2050 | Managed 2050 | Full Transformation 2050 |
|---|---|---|---|---|
| Blue Economy GDP | USD 9.6–10.5 bn | USD 20–25 bn | USD 35–42 bn | USD 45–55 bn |
| GDP Share | 11–12% | 14–16% | 20–23% | 25–28% |
| Jobs Supported | 4.5–6 million | 8–10 million | 14–17 million | 18–22 million |
| Annual Investment Needed | ~USD 1.2 bn | ~USD 2 bn | USD 4–6 bn | USD 7–10 bn |
| Coral Reef Health (%) | 60–70% | 40–50% | 65–75% | 75–85% |
The midpoint range of USD 40–50 billion represents the central 2050 Vision target, attainable under the Managed Transformation scenario with sustained political commitment and international partnership. This is not a best-case projection — it is achievable with the six recommendations in this report implemented on the specified timelines.
Five structural gaps and the subsectoral picture from 2020 through to the 2050 Vision.
Tanzania's blue economy has grown consistently in nominal terms over the past decade, though structural constraints — particularly in artisanal fisheries, aquaculture, and maritime services — have suppressed productivity gains. The table below presents the full subsectoral picture from 2020 through to 2050 Vision targets.
| Subsector | 2020 | 2025 Est. | 2035 Target | 2050 Vision |
|---|---|---|---|---|
| Total Blue Economy | USD 7.2 bn | USD 9.6–10.5 bn | USD 18–22 bn | USD 40–50 bn |
| Capture Fisheries | USD 1.1 bn | USD 1.4 bn | USD 2.5 bn | USD 4–5 bn (certified, traceable) |
| Coastal & Island Tourism | USD 0.7 bn | >USD 1 bn | USD 3 bn | USD 8–10 bn (eco & luxury focus) |
| Maritime Transport & Ports | USD 0.6 bn | ~USD 0.9 bn | USD 2 bn | USD 5–6 bn (deep-water hub) |
| Aquaculture | USD 0.08 bn | ~USD 0.15 bn | USD 1 bn | USD 6–8 bn (industrial + SME) |
| Seaweed Farming | USD 0.02 bn | ~USD 0.04 bn | USD 0.3 bn | USD 1.5 bn (processed & certified) |
| Offshore Energy (Wind/Tidal) | Nascent | Pilot stage | USD 0.5 bn | USD 8–10 bn (offshore wind clusters) |
| Blue Biotechnology | — | — | Emerging | USD 1–2 bn (research + products) |
| Blue Carbon / Ecosystem Credits | — | USD 0.01 bn | USD 0.2 bn | USD 1–2 bn (carbon markets) |
The 2050 Vision is not extrapolation of current trends. It requires structural transformation in three areas currently negligible: offshore renewable marine energy, blue biotechnology, and blue carbon markets. These three emerging sectors together could contribute USD 10–14 billion annually by 2050 — roughly equivalent to the entire current size of Tanzania's blue economy — if enabling conditions are established in the 2026–2035 decade.
A critical cross-cutting constraint on Tanzania's blue economy transformation — and on the credibility of its 2050 Vision — is the absence of reliable, timely, and harmonised data. Without real-time fisheries monitoring, investor-grade aquaculture statistics, and integrated coastal tourism accounting, neither the government nor the private sector can make evidence-based decisions or track progress against 2050 targets.
| Subsector | Current Status | Key Gaps | Impact on 2050 Vision |
|---|---|---|---|
| Fisheries | NBS annual surveys; 2–3yr lag | No VMS for artisanal fleet; no real-time stock monitoring | Stock collapse risk undetected; cannot certify sustainable fisheries for premium markets |
| Coastal Tourism | Zanzibar data reasonable; Mainland patchy | No integrated visitor-spend model; no ecosystem-tourism linkage data | Cannot attract premium investment; undersells blue economy's true contribution |
| Aquaculture | FAO estimates only; no national farm registry | No production census; no disease surveillance data | Cannot attract institutional investment; cannot manage sector biosecurity risks |
| Marine Ecosystems | TANGA coastal monitoring; ad hoc surveys | No national coral health index; no seagrass or mangrove mapping | Ecological collapse undetected; 2050 reef-dependent tourism targets at risk |
| Offshore Energy Resources | Very limited; some seismic surveys | No systematic offshore wind resource mapping | Cannot attract offshore energy investors; 2050 energy targets unreachable |
| Blue Economy GDP | UNECA 2020 estimate only | No updated national blue economy accounts | Sector invisible in national budget prioritisation; no 2050 progress tracking |
Tanzania's dual-governance structure creates both complexity and opportunity. The Zanzibar Revolutionary Government's autonomous authority over fisheries, tourism, and marine environment means that effective blue economy transformation requires seamless coordination between two governance systems with distinct legislative mandates, administrative cultures, and fiscal frameworks. Evidence indicates that this coordination is currently insufficient.
| Policy Area | Mainland Lead | Zanzibar Lead | Coordination Gap & 2050 Implication |
|---|---|---|---|
| Marine Fisheries | Ministry of Livestock & Fisheries | Min. of Blue Economy & Fisheries | Different licensing regimes; conflicting catch limits near shared waters. Without harmonisation, sustainable fisheries certification — essential for 2050 export targets — is unattainable. |
| Coastal Tourism | Min. of Natural Resources & Tourism | Zanzibar Commission for Tourism | Competing for the same tourist market without a joint destination brand. A unified brand is essential to reach USD 8–10 bn tourism target by 2050. |
| Marine Conservation / MPAs | NEMC / TAWA | Dept. of Environment (ZNZ) | MPAs governed under different standards. Without ecological connectivity planning, reef restoration investments will underperform. |
| Offshore Energy | EWURA / Ministry of Energy | ZEMA / ZRB | No joint framework for offshore wind or tidal licensing. Regulatory ambiguity will deter the USD 8–10 bn offshore energy investment pipeline. |
| Climate Adaptation | Vice President's Office (VPO) | Dept. of Environment (ZNZ) | Separate NDC implementation mechanisms. A joint coastal adaptation plan is necessary to protect 2050 tourism and fisheries infrastructure. |
Beyond Mainland-Zanzibar coordination, enforcement of fisheries regulations across Tanzania's 223,000 km² EEZ remains critically inadequate. IUU fishing is estimated to cost Tanzania USD 50–200 million annually. At 2050 scale — with a USD 4–5 billion certified sustainable fisheries sector — the cost of unchecked IUU fishing would be proportionally catastrophic. The investment in enforcement capacity required today is a precondition for the long-term revenue stream the 2050 Vision depends on.
Inclusivity is not merely a social equity objective in the context of Tanzania's blue economy — it is an economic imperative. With a population of 68 million growing toward 100–120 million by 2050, and a median age below 18, Tanzania's ability to achieve its 15–18 million jobs target depends entirely on systematically integrating youth and women into productive, well-remunerated blue economy roles. Current exclusion patterns represent a structural waste of human capital at precisely the moment it is most needed.
| Indicator | Current | 2030 Target | 2040 Target | 2050 Vision |
|---|---|---|---|---|
| Women in fisheries decision-making | <15% | 25% | 35% | >45% |
| Women's access to blue economy credit | ~8% | 20% | 35% | >50% |
| Youth in high-value blue sectors | <20% | 30% | 40% | >50% |
| Seaweed sector value-added share (%) | <5% | 20% | 45% | >70% |
| Community-based fishery co-management | Minimal | 30% inshore zones | 60% inshore zones | 100% inshore zones |
| Vocational training enrolment (blue) | ~5,000/yr | 30,000/yr | 70,000/yr | 150,000/yr |
Tanzania's seaweed farming sector — in which approximately 90% of 26,000 farmers are women — represents a microcosm of the broader inclusivity challenge. The sector is economically significant but structurally trapped at the raw commodity export stage, capturing less than 5% of the value that processed seaweed commands in global markets for cosmetics, pharmaceuticals, and food additives. Achieving the USD 1.5 billion seaweed target requires building a domestic processing industry while preserving women's ownership of the value chain.
Closing a USD 80–120 billion cumulative investment gap requires a fundamental redesign of Tanzania's blue finance ecosystem.
Closing the gap between Tanzania's current blue economy GDP of USD 9.6–10.5 billion and the 2050 Vision target of USD 40–50 billion requires cumulative investment of an estimated USD 80–120 billion over 25 years — approximately USD 3.2–4.8 billion annually on average. Current annual blue economy investment is estimated at USD 1.0–1.5 billion, concentrated in coastal tourism and maritime transport. The financing gap is structural: it cannot be closed through incremental increases in government spending but requires a fundamental expansion and diversification of the blue finance ecosystem.
| Finance Dimension | Current Status | Gap | Instrument Needed | 2050 Mobilisation Target |
|---|---|---|---|---|
| Sovereign Blue Bonds | USD 0 issued | No framework exists | Sovereign issuance with World Bank support | USD 2 bn+ cumulative |
| Blended Finance for Fisheries/Aquaculture | Minimal | No dedicated facility | IFC/DFI first-loss facility | USD 5 bn mobilised |
| SME Blue Credit | ~8% penetration | High collateral; no moveable asset finance | Vessel-backed credit, warehouse receipts | 50% SME formal credit access |
| Climate Finance (GCF/AF/CIF) | Limited pipeline | Few marine-specific proposals | GCF coastal resilience programme | USD 1 bn+ mobilised |
| Offshore Energy FDI | USD ~0 | No licensing framework | PPP concessions; IRENA partnership | USD 20–30 bn FDI |
| Parametric Insurance (fishers) | <5% fleet covered | Climate shocks uninsured | Index-based parametric products | 80% artisanal fleet insured |
| Blue Carbon Credits | USD ~10 m/yr | Mangrove/seagrass credits unissued | Verra/Gold Standard certification | USD 1–2 bn/yr credits |
Tanzania's mangrove forests — estimated at 130,000 hectares, among the largest remaining stocks in the Western Indian Ocean — sequester 2–5 times more carbon per unit area than tropical terrestrial forests. At current voluntary carbon market prices of USD 15–50 per tonne of CO₂, Tanzania's mangrove estate could generate USD 200–600 million annually in blue carbon credits if properly conserved, mapped, and certified. By 2050, the potential revenue could reach USD 1–2 billion annually — while simultaneously providing coastal protection, fish nursery habitat, and biodiversity services worth many times that value.
Climate change is not a future risk for Tanzania's blue economy — it is a present reality with an accelerating trajectory.
The Indian Ocean has warmed at approximately 0.18°C per decade since 1950, and IPCC AR6 projections indicate continued warming of 1.5–3°C above pre-industrial levels in East African coastal waters by 2050 under intermediate emissions scenarios. The implications for the blue economy's ecological foundations are severe and, without urgent intervention, potentially irreversible.
The critical insight from the climate risk analysis is that the cost of inaction vastly exceeds the cost of action. Coral reef degradation alone — if allowed to proceed to the 70–90% loss trajectory projected under a 2°C scenario — would eliminate the ecological foundation of both the reef tourism industry and the artisanal fisheries that feed and employ millions of coastal Tanzanians. Investing USD 20–30 million over the next decade in reef monitoring and restoration could protect an asset worth USD 5–10 billion annually by 2050.
| Climate Threat | Current Status | 2050 Projection (No Action) | 2050 if Action Taken | Affected Sectors |
|---|---|---|---|---|
| Sea-Level Rise | +3–5 mm/yr | 23–43 cm above 2000 baseline; major coastal inundation | 12–18 cm with adaptation | Tourism, fishing villages, ports |
| Coral Bleaching | 20–40% degraded | 70–90% reef loss under 2°C; near-total loss under 3°C | 30–40% loss with restoration | Reef tourism, artisanal fisheries, coastal protection |
| Ocean Acidification | pH –0.1 since 1900 | Further –0.2–0.3; shellfish/seaweed yields collapse | Managed through local stressor reduction | Seaweed, aquaculture, shellfish |
| Extreme Weather | Increasing frequency | Annual coastal damage USD 200 m–1 bn | USD 50–150 m with resilient infrastructure | All coastal and maritime sectors |
| Mangrove Loss | 1–2%/yr loss | 50–60% of current stock lost; USD 5 bn ecosystem service loss | Net gain of 30% with restoration | Fisheries, coastal protection, blue carbon |
| IUU Fishing | USD 50–200 m/yr loss | Stock collapse for key species by 2035–2040 | Sustainable harvest maintained with VMS + co-management | Artisanal fisheries, food security |
Three ten-year phases — Foundation, Acceleration, Transformation — with distinct priorities, milestones, and investment requirements.
The Tanzania Blue Economy 2050 Vision translates the sector's extraordinary potential into a structured, phased transformation programme. The phases are interdependent: the foundational investments and institutional reforms of Phase I (2026–2035) are prerequisites for the acceleration of Phase II (2036–2045), which in turn enables the full-scale transformation of Phase III (2046–2050+).

Six global comparators — what they achieved, how they did it, and the specific lessons for Tanzania's 2050 roadmap.
Tanzania's 2050 Vision is ambitious but achievable by the standards of comparable maritime economies that have made strategic advances in blue economy development. The six comparators below were selected for their direct relevance to one or more phases of Tanzania's roadmap — not as identical models, but as evidence that the instruments and outcomes Tanzania targets have been achieved elsewhere.
| Country | Strength Area | Key Instrument | Lesson for Tanzania | Applicable Phase |
|---|---|---|---|---|
| 🇸🇨 Seychelles | Blue Finance Pioneer | World's first sovereign blue bond (USD 15 m, 2018); debt-for-nature swap | Small island states can lead blue finance innovation; sovereign commitment unlocks private capital | Phase I (2026–2030): Issue Tanzania sovereign blue bond |

Six sequenced, actionable recommendations — each linked to a specific gap, phase, lead actor, financing requirement, and measurable milestone.
The following six recommendations are sequenced to address foundational enabling conditions in Phase I before sector-specific scaling in Phase II and III. Each is linked to a specific identified gap, phase of the 2050 roadmap, responsible actors, indicative financing requirements, and measurable milestones.
| # | Recommendation | Gap Addressed | Phase | Lead Actor | Key Milestone | Est. Cost |
|---|---|---|---|---|---|---|
| R1 | Establish National Blue Economy Data Hub | Data & Statistics | Phase I (by 2029) | NBS Tanzania + Zanzibar Statistical Office | Operational with real-time VMS & coral index by 2030 | USD 8–15 m (setup); USD 3–5 m/yr (ops) |
| R2 | Joint Mainland-Zanzibar Blue Economy Council | Governance | Phase I (by 2027) | PM's Office + Zanzibar Chief Minister's Office | Harmonised fisheries licensing & joint annual report by 2030 | USD 2–3 m/yr (Secretariat) |

A dedicated, technology-enabled National Blue Economy Data Hub — integrated with TRA, port authorities, DSFA, and the Zanzibar tourism commission — should be operational by 2029. It should encompass: real-time VMS data for all vessels over 10 metres; quarterly fisheries catch and aquaculture reports; an integrated coastal tourism expenditure model; a national coral reef and mangrove health index; and open-access data portals for international research partnerships. By 2035, the Hub integrates AI-powered predictive analytics for fish stock management — modelled on Norway's Institute of Marine Research. By 2050, the goal is a comprehensive digital twin of Tanzania's ocean economy.
A Joint Blue Economy Council, established by Presidential Decree or Act of Parliament with co-equal Mainland and Zanzibar representation, should meet quarterly. Its legally mandated remit must cover: joint licensing standards; coordinated marine spatial planning; shared performance reporting; and dispute resolution for cross-jurisdictional matters. By 2030 deliverables: a harmonised fisheries licensing framework; a single-window investment portal modelled on Mauritius's EDB; and a joint annual Blue Economy Performance Report. By 2045, the Council transitions into Tanzania's lead body for international ocean governance advocacy.
A gender-responsive, youth-centred programme operating in three tracks: (1) Vocational & Technical — skills training in aquaculture, marine engineering, dive tourism, seaweed processing, and digital fisheries monitoring for 50,000 young Tanzanians/yr by 2030, scaling to 150,000/yr by 2050; (2) Finance & Enterprise — a women's blue finance window within AFC offering collateral-free loans up to TZS 50 million, targeting 200,000 women clients by 2035; (3) Governance & Leadership — mandatory 40% women's representation in all government-constituted blue economy advisory and licensing bodies by 2030. A dedicated National Seaweed Value Chain Programme will raise the sector's processed value-added share from under 5% to over 70% by 2050, while maintaining women's ownership throughout.
Tanzania should issue its first Sovereign Blue Bond by 2028 — targeting USD 50–100 million in the inaugural issuance, structured with World Bank technical assistance and aligned with ICMA Green and Social Bond Principles. Proceeds ringfenced for: sustainable marine fisheries management; MPA operational costs; coastal climate adaptation. Simultaneously, a Blended Finance Facility for Aquaculture and Fisheries Modernisation should be established by 2027, with a first-loss tranche of USD 20–30 million designed to crowd in USD 150–200 million in commercial bank lending to artisanal and SME operators. TICGL should lead the development of a portfolio of Verra-certified mangrove and seagrass carbon credit projects, targeting USD 200–300 million in annual revenues by 2035 rising to USD 1 billion by 2050.
Marine Spatial Planning (MSP) is the foundational governance instrument for managing competing uses of Tanzania's ocean space — fisheries, tourism, conservation, shipping, offshore energy, aquaculture — while maintaining ecological integrity. Without it, the sectoral targets of the 2050 Vision will conflict spatially and erode each other's performance. Key deliverables: a National MSP covering Tanzania's full EEZ by 2028 and adopted by legal instrument by 2030; MPA coverage of 20% of Tanzania's EEZ by 2030 and 30% by 2050 (consistent with Kunming-Montreal GBF); offshore wind and tidal development zones identified within the MSP by 2030. The MSP must also serve as Tanzania's primary climate adaptation instrument for the coast, designating buffer zones, mangrove restoration areas, and climate retreat corridors.
Aquaculture PPPs: Protected Marine Aquaculture Zones designated by 2028, with 20–25 year concession agreements, bankable step-in rights, and 15% revenue sharing to adjacent fishing communities. Target: 800,000 mt/yr production and USD 6–8 billion GDP by 2050. Eco-Premium Coastal Tourism: A Tourism Concession Framework for MPAs developed by 2027 — modelled on Seychelles' island resort model — targeting USD 500 million in eco-tourism investment within five years. Offshore Renewable Marine Energy: First Offshore Wind Development Framework published by 2028, identifying priority zones, competitive licensing, and domestic content requirements. First commercial projects commissioned by 2038; USD 8–10 billion output by 2050.
Tanzania's blue economy 2050 Vision is not a projection of what will happen — it is a description of what could, and must, happen.
The Tanzania Blue Economy 2050 Vision presented in this report is not a projection of what will happen if current trends continue. It is a description of what could happen — and what must happen — if Tanzania makes deliberate, coordinated, and sustained policy choices over the next 25 years. The analytical evidence assembled demonstrates both the extraordinary potential of Tanzania's blue economy and the stark clarity of the gaps that currently prevent that potential from being realised.
The central finding is that Tanzania's blue economy gap is not primarily a resource gap. The natural endowments are extraordinary. The policy vision — articulated in the National Blue Economy Policy (2024) and the Zanzibar Blue Economy Policy (2020) — is sound. The global demand for sustainable seafood, ocean-based clean energy, blue carbon credits, and high-quality marine tourism is expanding rapidly.
The gap is institutional, informational, financial, and human. It is a gap in data systems, in governance coordination, in inclusive human capital development, and in financial instruments. All of these gaps are closeable. None requires a technological breakthrough or external conditions beyond Tanzania's influence. They require political commitment, institutional coordination, and sustained investment in enabling conditions — the foundational work of Phase I (2026–2035) from which all subsequent transformation flows.
TICGL — Tanzania Investment and Consultant Group Ltd — is committed to continuing to build the evidence base, facilitate stakeholder dialogue, and advocate for the policy reforms this transformation requires. Priority areas for future TICGL research include: primary data collection on SME financing barriers in artisanal fisheries communities; gender-disaggregated value chain analysis of the seaweed and aquaculture sectors; and economic modelling of the offshore wind investment pipeline.

Ripoti hii ya TICGL — Tanzania Investment and Consultant Group Ltd — kwa lugha ya Kiswahili.
Ripoti hii ya TICGL inafanya mambo mawili kwa wakati mmoja: inagundua na kuchambua mapungufu ya msingi yanayokwaza uchumi wa buluu wa Tanzania leo, na wakati huo huo inabainisha dira ya muda mrefu — Dira ya Uchumi wa Buluu wa Tanzania 2050 — ambayo inaonyesha njia ya wazi kutoka hali ya sasa kwenda mustakabali ambapo uchumi wa buluu ni nguzo kuu ya Tanzania yenye ustawi, ushirikishwaji, na ustahimilivu wa kimazingira.

Dola milioni 50–100 — ifikapo 2028 — kwa msaada wa Benki ya Dunia na kwa mujibu wa ICMA.
Ufunikaji kamili wa EEZ, ukishirikiana na Zanzibar — Mpango tayari 2028, kupitishwa kisheria 2030.
Ufugaji wa samaki, utalii wa ikolojia wa pwani, na nishati ya baharini — miundo ya PPP katika Awamu I, upanuzi katika Awamu II–III.
TICGL — Tanzania Investment and Consultant Group Ltd — inaendelea kutoa utafiti wa kisayansi na mazungumzo ya wadau ili kuunga mkono mabadiliko haya ya muda mrefu. Dira ya 2050 inawezekana — lakini inahitaji dhamira ya kisiasa, uratibu wa kitaasisi, na uwekezaji endelevu katika misingi inayoiwezesha. Uchumi wa buluu wa Tanzania ni urithi wake wa bahari — na kwa ramani hii, uko ndani ya uwezo wake.
