Mauritius holds almost no mineral or energy endowment. The island is volcanic basalt, with no significant metal reserves or production, no domestic smelting or refining, and only basalt and aggregate quarrying and coral and lime for construction. There are no oil or gas reserves and no refinery. Mauritius imported 90.9 per cent of its primary energy requirement in 2024, of which petroleum products were 61.1 per cent and coal 29.8 per cent. Installed generation capacity was about 955 MW in 2023 against peak demand of about 508 MW, and electricity generation reached 3,417.6 GWh in 2024, of which 81.8 per cent was non-renewable and 18.2 per cent renewable. The renewable share rests mainly on bagasse, the residue of sugar cane, which supplied 9.1 per cent of generation in 2022, together with solar photovoltaics, hydro of about 56.5 MW installed, wind and landfill gas. The government targets 60 per cent renewable electricity by 2030 with a coal phase-out.
The productive endowment is agricultural and marine rather than mineral. Sugar cane occupies roughly 90 per cent of cultivated land. Sugar production was 238,854 tonnes in 2023 against a long-run average of 537,155 tonnes and an all-time high of 706,839 tonnes in 1986, a structural decline of roughly two-thirds from peak. The sector has pivoted to about 70 per cent refined white sugar, EEC Grade 2, and about 30 per cent unrefined special sugars across fifteen varieties, with roughly 90 per cent of output exported. Fisheries are the standout: the EEZ and access to the Western Indian Ocean industrial tuna fishery feed a major canning and loining complex, and Mauritius was Africa's single largest preserved-tuna producer by volume at 52,000 tonnes in 2024. Forestry and timber are negligible, and the country is a net food importer while remaining self-sufficient in some fresh vegetables, poultry and eggs.
The manufacturing base is light, named and clustered. Textiles and clothing accounted for 25.42 per cent of manufacturing value added in 2022, while the export-oriented enterprises' share of manufacturing gross value added fell from 53 per cent in the 1980s to about 30 per cent in 2023. In seafood, Princes Tuna (Mauritius) holds annual raw-material processing capacity of about 50,000 tonnes and Thon des Mascareignes about 55,000 tonnes, capable of some 200 tonnes per day; with two further minus 40 and minus 60 degree units, Mauritius held about 105,000 tonnes a year of processing, the largest in the Western Indian Ocean. Supporting firms include the IBL conglomerate, Froid des Mascareignes, Indico Canning, Marine Biotechnology Products in fishmeal, and the Chantier Naval de l'Océan Indien shipyard, with Mitsubishi and Echebastar as foreign anchors. Sugar runs through three enlarged mills, Altéo, Terra and Omnicane, with the Mauritius Sugar Syndicate as sole marketing arm. Seven medical-device manufacturers employed about 800 people in 2022, among them Natec Medical, AVA Medical and Envaste, producing catheters, stents and implants; six distilleries produce rum and cane spirits. On economic complexity, Mauritius is the most, or close second-most, complex economy in Sub-Saharan Africa, statistically near-tied with South Africa, with a Harvard Atlas ECI improving from approximately minus 0.46 in 2000 to about 0.09 in 2022 and a global rank moving from 90th to 58th of 133 countries.
The endowment in depth
Mauritius carries almost no mineral or energy endowment, and the honest reading of its balance sheet begins there. The island is volcanic basalt and is essentially devoid of metallic and industrial-mineral resource: there are no significant metal reserves or production, no domestic smelting or refining, and the only domestic mineral activity is basalt and aggregate quarrying plus coral and lime for construction. The apparent "diamond" exports of US$185 million in 2023 (OEC) are cut, polished or re-exported stones worked from imported rough — there is no domestic diamond mining. Energy is the tighter constraint. Mauritius has no oil or gas reserves and no refinery, and imported 90.9% of its primary energy requirement in 2024 (petroleum products 61.1%, coal 29.8%, per US ITA citing Statistics Mauritius). Installed generation capacity is roughly 955 MW (2023, Statistics Mauritius/CEB) against peak demand of about 508 MW; generation reached 3,417.6 GWh in 2024, of which 81.8% was non-renewable and 18.2% renewable, the latter mostly bagasse (9.1% of generation in 2022), solar PV, hydro (about 56.5 MW installed), wind and landfill gas. Government targets 60% renewable electricity by 2030 with a coal phase-out, but the Central Electricity Board reported losses exceeding Rs 4.8 billion (about US$320 million) in 2023 on volatile fuel costs, and a 2025 capacity squeeze forced emergency stop-gap measures. Power is import-dependent, relatively costly and a binding limit on any energy-intensive manufacturing.
The genuine endowment is agricultural and marine. Sugarcane dominates the land, occupying roughly 90% of cultivated area, but the sector has contracted sharply: sugar production was 238,854 tonnes in 2023 against a long-run average of 537,155 tonnes and an all-time high of 706,839 tonnes in 1986 — a structural fall of about two-thirds from peak. The cluster has pivoted to roughly 70% refined white sugar (EEC Grade 2) and about 30% unrefined special sugars across 15 varieties, with around 90% of output exported. Fisheries are the standout: the maritime economic zone and access to the Western Indian Ocean industrial tuna fishery feed a major canning and loining complex, and Mauritius was Africa's single largest preserved-tuna producer by volume at 52,000 tonnes in 2024 (IndexBox). Forestry and timber are negligible. The island is a net food importer but is self-sufficient in some fresh vegetables, poultry and eggs (Mauritius Chamber of Agriculture).
The existing industrial base is the most sophisticated in Sub-Saharan Africa despite the absence of raw materials. Textiles and clothing accounted for 25.42% of manufacturing value added in 2022 (World Bank), though the export-oriented enterprises' share of manufacturing GVA has fallen from 53% in the 1980s to about 30% in 2023. In seafood, Princes Tuna (Mauritius) runs annual raw-material processing capacity of about 50,000 tonnes and Thon des Mascareignes about 55,000 tonnes (capable of roughly 200 MT/day); with two additional −40°C/−60°C units, Mauritius held about 105,000 tonnes per year of processing, the largest in the Western Indian Ocean (IDDRI, 2018). Supporting firms include the IBL conglomerate, Froid des Mascareignes, Indico Canning, Marine Biotechnology Products (fishmeal) and the Chantier Naval de l'Océan Indien shipyard, with foreign anchors Mitsubishi (Princes) and Echebastar (Spain). Sugar runs through three enlarged mills — Altéo, Terra and Omnicane — with the Mauritius Sugar Syndicate as sole marketing arm. Medical devices comprise seven manufacturers (2022) employing about 800 people, led by Natec Medical (angioplasty/PTCA catheters, claiming the Indian Ocean's largest cleanroom), AVA Medical and Envaste, producing catheters, stents and implants. Six rum distilleries operate — Grays (New Grove; capacity 7 million litres of pure alcohol per year), Medine (Penny Blue, Pink Pigeon/Diageo), Chamarel, St Aubin, Labourdonnais and Oxenham — alongside a diamond-cutting trade running since 1970 (LSP/Mauriden, Adamas) and a large legacy knitwear and T-shirt base in the former Export Processing Zone.
Human capital and logistics complete the picture. The labour force is roughly 0.6 million; the sectoral minimum wage was MUR 17,110 per month in 2025 (Statistics Mauritius) and the average monthly wage about US$846 in 2023, with unemployment down to about 5.6% in 2025. Skill clusters exist in financial services, ICT/BPO, textiles, seafood processing and hospitality, but rising labour costs are eroding low-cost apparel competitiveness versus Bangladesh, Vietnam and Ethiopia (Fibre2Fashion, 2023). Infrastructure is a real asset: Port Louis handles about 99.5% of external trade, with container throughput of roughly 400,000 TEU against about 1 million TEU capacity following the 2017 terminal extension (16.5 m draft) — one of the deepest ports in the South-West Indian Ocean. The Mauritius Freeport is a re-export and transhipment platform with EU-standard cold-chain fish-handling facilities. Island geography means all heavy inputs are imported and all outputs must be shipped, which favours high-value, low-bulk goods and penalises bulk commodities while positioning the island to serve landlocked African markets.
Economic complexity & comparative advantage
Mauritius is the most, or a close second-most, economically complex economy in Sub-Saharan Africa, statistically near-tied with South Africa. The Harvard Atlas Economic Complexity Index improved from approximately −0.46 in 2000 to about 0.09 in 2022, lifting its global rank from 90th to 58th of 133 countries (BIZWEEK citing the Atlas of Economic Complexity). A separate Harvard-sourced compilation records the ECI at −0.17 in 2021 with a four-position rank gain over five years and a Complexity Outlook Index of about 0.25 (2021); the absolute values differ by edition and data-cleaning method, so the level should be read as indicative while the "most-complex-in-SSA" standing is firm. The most-specialised products by revealed comparative advantage (OEC, 2023) are "Other Animals" at 478 (live primates for biomedical research), non-retail carded wool yarn at 211, processed fish at 132, other clocks and watches at 77.3, and vanilla at 61.3.
The relatedness read points to adjacent, not transformative, opportunities. Atlas relatedness-based diversification openings (OEC, 2023) cluster around existing seafood and apparel capabilities — crustaceans, knit men's undergarments, packing bags, cassava and bananas. Despite a relatively high ECI for its region, the export basket remains dominated by low-complexity products (textiles, apparel and fish preparations), which limits near-term upward mobility: complexity gains would have to come from moving up within the seafood, sugar and garment value chains rather than from a leap into an unrelated high-complexity sector.
The trump card · the single strongest continental position
Mauritius's single most defensible continental supply position is canned and processed tuna and seafood (HS16/HS1604), and it earns that status by being the only category that scores YES across all five lens criteria at once. On the input base, a large EEZ plus access to the Western Indian Ocean industrial tuna fishery is landed and transhipped through Port Louis, and Mauritius was Africa's largest preserved-tuna producer by volume at 52,000 tonnes in 2024 (IndexBox). On processing, this is finished-goods manufacturing rather than raw export: Princes Tuna (Mauritius) at about 50,000 tonnes of capacity and Thon des Mascareignes at about 55,000 tonnes (roughly 200 MT/day) together gave Mauritius about 105,000 tonnes per year of processing, the largest in the Western Indian Ocean (IDDRI, 2018), with by-product fishmeal and fish-oil lines. On competitiveness, processed fish carries an RCA of 132 (OEC, 2023) and canned tuna was the leading single export at about US$247 million in 2024 — the second-largest African exporter by value after Seychelles (US$278 million) and ahead of Ghana (US$148 million) (IndexBox, 2024). Deliverability rests on EU-standard HACCP processing, an integrated cold chain and a deep transhipment port, and the continental demand is real: the African preserved-tuna market was worth US$1.2 billion in 2024, with importers including Libya (US$194 million), Egypt (US$132 million) and Algeria (US$61 million), plus South Africa, Somalia and Ethiopia.
The honest limits are equally clear and a minister should weigh them. The raw-material base depends on foreign-flagged fleets and fishing agreements rather than domestically controlled supply; ownership is concentrated in a few foreign-linked groups (Mitsubishi/Princes, Echebastar); the sector has historically depended on European markets and is exposed to tariff-preference shifts and to Thai and Ecuadorian competition; over-fishing and Indian Ocean Tuna Commission quota risk sit over the resource; and per-capita demand is thin outside North Africa. The position is defensible because it is finished-goods manufacturing built on genuine processing scale, sanitary standards and port logistics rather than on a raw endowment — but its durability turns on securing raw-material supply and diversifying markets beyond Europe and North Africa.
