Three Gorges Dam
EnergyThe world's largest hydropower station by installed capacity, at 22.5 GW, and the main flood-control structure on the Yangtze.
The islands, with large bird and seal populations, lie approximately 1,000 km east of the Falkland Islands and have been under British administration since 1908 - except for a brief period in 1982 when Argentina occupied them. Grytviken, on South Georgia, was a 19th and early 20th century whaling station. Famed explorer Ernest SHACKLETON stopped there in 1914 en route to his ill-fated attempt to cross Antarctica on foot. He returned some 20 months later with a few companions in a small boat and arranged a successful rescue for the rest of his crew, stranded off the Antarctic Peninsula. He died in 1922 on a subsequent expedition and is buried in Grytviken. Today, the station houses scientists from the British Antarctic Survey. …
The National Infrastructure Index maps the physical assets national life runs on — power stations and grids, water systems, ports, railways and airports, data networks, payment systems and launch sites. Each asset is placed in a Strategic Infrastructure capability group, so it can be read against the ratings in the National Capability index above.
Assets are chosen for how much of the economy and state depends on them and how hard they would be to replace. Each card records what the asset is, the category it belongs to, what it does and where it is.
Example assets. These twenty cards are modelled on China's most critical infrastructure and show on every nation page until each nation's own assets are mapped.

The National Development Index tracks the events that move a nation's capability — policy decisions, technological milestones, economic turns and external shocks — and places each one on the record with the date it happened and what followed from it. It is the narrative counterpart to the indices: where a rating says where the South Georgia and South Sandwich Islands stands, the index says how it arrived there.
Recent developments cover the current cycle, close enough that their consequences are still unfolding. Historical developments are the inflection points behind the present position — the decisions and events a reader needs in order to read the ratings above in context.
The London merchant Anthony de la Roché, an Englishman despite his French name, spent a fortnight in one of the island's bays. The island appeared as Roche Island on early maps, giving South Georgia its first place in European cartography.
The commercial vessel León recorded a sighting of South Georgia on 28 or 29 June 1756. The encounter added to the sparse pre-Cook record of the island.
Cook made the first landing on the island and named it the Isle of Georgia in honour of King George III. The claim is the foundation of British sovereignty over the territory.
Cook tentatively named the group Sandwich Land after John Montagu, 4th Earl of Sandwich, First Lord of the Admiralty, while noting it might be a group of islands. The word South was later added to distinguish them from the Hawaiian Islands.
Sealing began in 1786 and continued throughout the 19th century, making the island an early resource frontier. The treacherous waters wrecked numerous vessels, including the Earl Spencer in late 1801.
Commercial sealing on the islands ran from 1817 to 1909, forming the territory's first sustained economic activity. It preceded and overlapped with the rise of shore-based whaling.
The Russian explorer found the three northern islands in 1819 and in 1820 confirmed that Cook's southernmost three were separate islands. During his 1819–21 Antarctic expedition he also assigned six new place names within the territory.
British arrangements for the government of South Georgia were set out under letters patent issued in 1843. This gave the island its first formal constitutional footing under the Crown.
The scientists observed the transit of Venus and recorded waves produced by the 1883 eruption of Krakatoa. The expedition left a legacy of German place names on the island.
The British Overseas Territory abandoned local mean time in 1890. It aligned the islands with modern timekeeping for shipping and administration.
Carl Anton Larsen, a Norwegian, founded the island's first land-based whaling station and first permanent habitation at Grytviken in 1904, operating through his Argentine Fishing Company under leases granted by the Governor of the Falkland Islands. Seven whaling stations eventually operated on the sheltered north coast; Grytviken ran until 1965 and today houses scientists from the British Antarctic Survey.
From 1905 Argentina helped maintain the observatory under the British lease requirements imposed on the whaling station. The arrangement lasted until the lease terms changed in 1949.
The 1908 letters patent set constitutional arrangements for South Georgia, the South Orkneys, the South Shetlands, the South Sandwich Islands and Graham Land. This formalised British administration of the whole South Atlantic sector.
A residence and resident magistrate were installed near Grytviken, giving Britain effective possession through enforcement of law and regulation of economic and scientific activity. The territory was then governed as part of the Falkland Islands Dependencies.
Reindeer were brought in for meat and sport hunting in 1911. They spread across the island and damaged native species, prompting a total cull a century later.
According to some accounts a 110-foot blue whale was brought ashore at Grytviken in about 1912. It marked the peak of the island's whaling industry.
Ernest Shackleton stopped at Grytviken in 1914 en route to his ill-fated attempt to cross Antarctica on foot. After the Imperial Trans-Antarctic Expedition was stranded on Elephant Island, Shackleton and five companions reached King Haakon Bay on South Georgia on 10 May 1916 after some twenty months, and three of them crossed the mountainous spine of the island to Stromness whaling station. The remaining 22 men on Elephant Island were subsequently rescued, making South Georgia central to one of polar exploration's defining episodes.
The 1908 letters patent were widened in 1917 to cover a wedge of Antarctica extending to the Pole. This entrenched the dependency structure that governed South Georgia until 1985.
The explorer died during a later expedition while moored off South Georgia. His grave at Grytviken became the island's principal heritage site.
Argentina asserted a claim to the island in 1927, a claim whose basis has been questioned. It began the sovereignty dispute that would culminate in the 1982 conflict.
Argentina extended its South Atlantic claims to the South Sandwich group in 1938 and challenged British sovereignty there on several later occasions. The claim underpinned Argentine installations on Thule Island from the 1950s.
During the Second World War an armed merchant vessel patrolled South Georgian and Antarctic waters, and two four-inch shore guns protected Cumberland Bay and Stromness Bay. The guns, still present, were manned by volunteers from among the Norwegian whalers.
Martin-Reynolds assumed the post on 29 July 2025. The Commissioner heads the territory's government under the 1985 constitution.
On 11 September 2020 a representative was appointed to the committee and three new criteria were set for approving names in the territory. This replaced the 1956 ordinance and 1957 regulation.
The rodent eradication effort ended apparently successfully in June 2015. An intensive six-month search in 2017–18 by the South Georgia Heritage Trust using sniffer dogs and traps found no rodents, South Georgia pipit numbers had clearly risen by 2018, and the island remained rat-free in 2024 with a permanent team inspecting incoming vessels.
On 23 February 2012 the government designated an MPA covering 1.07 million square kilometres to protect marine biodiversity. It is one of the largest protected marine areas in the world.
Citing the reindeer's harm to native species and the risk of spread into pristine areas, the government announced full eradication. Culling began in 2013 with 3,500 animals killed, nearly all the rest in early 2014, and the last 50 in the 2014–15 southern summer.
A four-year project led by zoologist Anthony Martin of the University of Dundee aimed to remove rats and mice introduced by sealing and whaling ships in the late 18th century, which had destroyed tens of millions of birds' eggs and chicks. In May 2013, 180 tonnes of brodifacoum were dropped over 70 per cent of the island, with a further 95 tonnes planned for January 2015.
The ashes of Shackleton's second-in-command on the Imperial Trans-Antarctic Expedition were buried next to him. It reinforced Grytviken's status as a memorial site of Antarctic exploration.
A study conducted between 2009 and 2011 identified South Georgia's ecosystems as among the richest globally. The finding strengthened the case for marine and terrestrial protection measures.
The Royal Navy ice-patrol ship, which had operated around South Georgia during most southern summers, was nearly lost to flooding in 2008. The Ministry of Defence bought the vessel outright in September 2013 and announced on 7 October 2013 that she would be sold for scrap.
The full-time garrison maintained after the Falklands War was scaled down through the 1990s and left in March 2001. A new station was built and occupied by the British Antarctic Survey, restoring the base to science.
The MSC cited the territory for its sustainable Patagonian toothfish fishery, certifying that it met the council's environmental standards. Fishing licences now supply 80 per cent of the territory's £6.3 million revenues.
A series of cases between 2001 and 2005, notably Regina v. Secretary of State for Foreign and Commonwealth Affairs ex parte Quark Fishing Limited, examined the 1985 constitution, the direction of the territory's government and the availability of judicial review. The House of Lords judgment of 2005 clarified the legal position of the territory's executive.
Recognising the importance of preserving marine stocks in adjacent waters, the UK in 1993 extended the exclusive fishing zone from 12 to 200 nautical miles around each island.
In 1985 South Georgia and the South Sandwich Islands ceased to be administered as a Falkland Islands Dependency. A constitution for the new territory was adopted on 3 October 1985.
On 20 June 1982 the Argentine naval station was dismantled following Argentina's defeat in the Falklands War. This ended the physical Argentine presence in the South Sandwich Islands.
The island was retaken on 25 April 1982, the first British success of the Falklands War. The date is now marked annually as Liberation Day in the territory.
On 3 April 1982 Argentine forces seized the settlement on South Georgia. Among the garrison's commanders was Alfredo Astiz, later convicted of crimes against humanity committed during Argentina's Dirty War.
On 19 March 1982 a group of Argentinians, mostly marines in mufti, landed at the abandoned station on South Georgia. The incident precipitated the Falklands War.
The base was constructed on 7 November 1976 on the southern east coast of Thule Island. Britain discovered it in 1976 and protested diplomatically, but made no attempt to remove it by force before the Falklands War.
The Place-names Ordinance of 1956 and Place-names Regulation of 1957 governed the adoption of new place names in the territory. They remained in force until superseded in 2020.
From 25 January 1955 to mid-1956 Argentina maintained a summer base at Ferguson Bay on the southeastern coast of Thule Island. It was an early physical assertion of the Argentine claim to the South Sandwich Islands.
The base was rebuilt as a scientific station by the body that was renamed the British Antarctic Survey in 1962. This established the territory's enduring role as a platform for polar science.
The islands, with large bird and seal populations, lie approximately 1,000 km east of the Falkland Islands and have been under British administration since 1908 - except for a brief period in 1982 when Argentina occupied them. Grytviken, on South Georgia, was a 19th and early 20th century whaling station. Famed explorer Ernest SHACKLETON stopped there in 1914 en route to his ill-fated attempt to cross Antarctica on foot. He returned some 20 months later with a few companions in a small boat and arranged a successful rescue for the rest of his crew, stranded off the Antarctic Peninsula. He died in 1922 on a subsequent expedition and is buried in Grytviken. Today, the station houses scientists from the British Antarctic Survey. Recognizing the importance of preserving the marine stocks in adjacent waters, the UK, in 1993, extended the exclusive fishing zone from 12 nm to 200 nm around each island.

Some fishing takes place in adjacent waters. There is a potential source of income from harvesting finfish and krill. The islands receive income from postage stamps produced in the UK, sale of fishing licenses, and harbor and landing fees from tourist vessels. Tourism from specialized cruise ships is increasing rapidly.
