As the world’s largest archipelagic nation, the Republic of Indonesia’s future is inextricably linked to the vast expanse of its ocean territory. Securing this critical domain and sustainably harnessing its economic potential, known domestically as the 'blue economy', represents the paramount strategic objective for the government and military command.

To achieve this dual mandate, Indonesia has deliberately leveraged high-level international collaborations and fostered domestic industrial autonomy. These efforts are focused on elevating the operational capacity of the naval and maritime security forces and addressing fundamental structural deficits in the nation's legal and economic governance. The recent $5bn strategic understanding with the United Kingdom, as reported by Forces News, and the ongoing technological programme with Greek defence company Scytalys for maritime surveillance aircraft, as reported by Jakarta Globe, serve as a national push towards enhanced regional security and economic diversification.

Indonesia’s blue economy: The government’s next resource potential

Indonesia’s maritime territory represents an enormous untapped resource, yet its contribution to the national Gross Domestic Product (GDP) currently stands at only around 7%, Maritime Fairtrade reports. This modest figure is due, in part, to an inefficient and fragmented legal structure governing maritime affairs, which necessitates a complete reorganisation to properly facilitate investment and sustainable economic practices. The blue economy, which includes responsible management of marine resources, logistics, and transportation, requires a balanced national prioritisation that currently appears to favour large-scale, land-based ventures. Realising the full wealth potential of the sea depends entirely on resolving these domestic policy inconsistencies and ensuring regulatory clarity for citizens and international investors alike.

The $5bn maritime sovereignty boost

The multi-year, strategic accord with the United Kingdom, valued at an estimated $5bn, is a central element in strengthening Indonesia’s defence capabilities and accelerating the national shipbuilding industry. Forces News reports that this covenant is designed to transfer critical naval-vessel development expertise from the UK, primarily through the participation of the British firm Babcock. Critically, the structure dictates that the naval vessels themselves will be constructed within Indonesian yards, serving as a powerful catalyst for local investment and the upskilling of our workforce. President Prabowo Subianto noted that this initiative is a transformative step forward, enabling the nation to domestically develop and construct our own essential vessels, supported by the technology and experience of a key partner.

The benefits of this alliance extend far beyond naval requirements. The programme is also committed to producing over one thousand vessels for the nation’s fishing fleets, which is a direct policy measure aimed at bolstering domestic seafood consumption and improving our overall national food security, Dunfermline Press reports. This holistic approach underscores Jakarta’s view of maritime power as inseparable from economic stability. The two countries are further cementing their strategic relationship by jointly conducting research into advanced shipbuilding practices, including the future application of automation and Artificial Intelligence (AI) within the manufacturing process, Forces News reports.

This high-profile military export to an Indo-Pacific partner is also indicative of the UK's wider success in securing substantial covenants, such as the $12.5bn opportunity for anti-submarine warships for Norway and the $10bn Typhoon fighter jet compact with Turkey. Prime Minister Sir Keir Starmer emphasised that these alliances yield economic dividends for the partner nation, specifically securing roughly 1,000 employment roles in Britain, mainly in the Rosyth area, Dunfermline Press reports. For Indonesia, the greater reward lies in the long-term structural uplift of the shipbuilding sector and the improved naval interoperability and joint training facilitated by the programme, which reinforces our collective commitment to a rules-based international order and freedom of navigation.

The imperative for domestic legal reform for the Blue Economy

To truly maximise the economic potential of our vast marine resources, the Indonesian government must urgently tackle internal structural impediments, particularly the need for comprehensive legal reorganisation, as reported by Maritime Fairtrade. Experts have repeatedly stressed that the current fragmented legal statutes are simply insufficient for managing the complexities of contemporary maritime affairs and are detrimental to the national push for sustainable economic growth. The lack of clarity, for example, has resulted in high-profile incidents involving the seizure of fishing vessels based on ambiguous policy interpretations, leading to regulatory uncertainty and discouraging investment.

A crucial proposed remedy involves the establishment of a dedicated Maritime Commercial Court, also known as an Admiralty Court, as reported by Maritime Fairtrade. Such a specialised judicial body would enhance the effectiveness of law enforcement, substantially reducing the current judicial sluggishness and regulatory overlap that currently plagues dispute resolution in the sector. The profound necessity of this legal certainty was highlighted by the 2020 Batam incident, where the impounding of vessels carrying essential goods caused significant disruption to supply chains, directly contributing to undesirable escalations in market prices.

Furthermore, the full scope of the blue economy must be accurately reflected in national policy and prioritisation. Whilst embracing the vital role of traditional sectors like logistics, Professor Luky Adrianto underscores that the focus must expand to include the responsible management of all aquatic and marine resources, including the need for firm regulation of resource extraction, such as deep-sea mining and oil and gas exploration, to mitigate potential ecological damage. The prevailing sentiment is that national planning must achieve a more appropriate balance, moving away from an excessive focus on terrestrial ventures and giving the non-extractive, environmentally responsible marine sector the central, strategic role it deserves for accelerating GDP growth.

Strategic alliances to advance technical autonomy

In parallel with securing high-level external collaborations and tackling domestic reform, Indonesia is demonstrating its commitment to technical self-reliance through the development of specialised indigenous aircraft platforms. The state-owned aerospace manufacturer, Dirgantara Indonesia (DI), also entered into a strategic programme with the Greek defence enterprise Scytalys for the co-development of a high-technology maritime surveillance aircraft (MSA), Jakarta Globe reports. This compact is especially significant as the MSA will be based on the locally designed and manufactured N219 Nurtanio platform, a major achievement for the national aerospace industry.

The N219 was originally conceived as a short take-off and landing (STOL) civilian transport plane, perfectly suited for the remote and rugged environments within the archipelagic nation. Its current configuration for military and paramilitary roles, achieved through this new alliance, represents a major step forward in national technical maturation. DI will take the lead role as the primary contractor for the aircraft’s configuration, while the Greek partner, Scytalys, will provide the expertise for integrating the sophisticated surveillance technology.

The resulting MSA will be equipped with the MIMS Airborne Mission System, providing advanced digital tracking capability. Its sensor suite includes an electro-optical sensor with a 20 kilometre detection range and a radar system capable of surveying up to 160 nautical miles, making it an invaluable national asset for the Maritime Security Agency (Bakamla). Bakamla has already requested four units, reaffirming its commitment to utilising domestically produced equipment. The technology, including a tactical datalink for real-time target transmission, is crucial for closing existing surveillance gaps in remote border waters, thereby directly supporting the nation’s ability to project security across its territorial sea and uphold its maritime interests.

 

Niger puts nationalised Somair uranium on global market amid standoff with France’s Orano

Niger puts nationalised Somair uranium on global market amid standoff with France’s Orano

Niger’s military government has announced it will begin selling uranium produced by Somair on the international market, months after nationalising the mine previously operated by French nuclear-fuel group Orano. The statement was broadcast on state television Tele Sahel on November 30 and cited junta leader General Abdourahamane Tchiani.

Somair, established in 1971 and historically co-owned by Orano and the Nigerien state, has long been one of Niger’s most important uranium assets, typically accounting for roughly one-third of national production.

Niger is the world’s seventh-largest uranium producer, with annual output averaging 2,020–2,500 tonnes in recent years, according to the World Nuclear Association. Orano, which is 90% owned by the French government, has supplied nuclear fuel to European utilities for decades from its Nigerien operations.

Tele Sahel reported that Tchiani asserted Niger’s right to sell its mineral resources independently “to whoever wants to buy them,” according to the broadcast summary. The government did not disclose buyers, contract structures or expected volumes. Any diversion from earlier offtake arrangements could raise contractual-compliance and traceability questions for potential customers, particularly in regulated markets such as the EU, the US and Japan, where nuclear-material origins must be documented.

The dispute also encompasses Orano’s rights to Imouraren, one of the world’s largest undeveloped uranium deposits. The project has been delayed for years—officially due to market conditions—becoming a recurring source of tension between Niamey and Paris.

France has historically relied on Niger as one of its key uranium suppliers, and Niger was among the EU’s top-three uranium exporters before the 2023 coup, although French utilities have diversified their sourcing towards Kazakhstan, Canada and Uzbekistan.

Relations between the junta and France deteriorated sharply after the 2023 military takeover, followed by Niamey’s expulsion of French troops and suspension of defence and cooperation agreements. Orano has maintained that it retains legal rights to its assets and has warned that security, environmental-compliance and operational conditions have deteriorated around its sites since 2023.

Russia has publicly signalled interest in Niger’s uranium sector. Russian Energy Minister Sergei Tsivilev said in July that Moscow was “keen to explore mining opportunities” in the country, although Niger’s Ministry of Mines has not announced any binding agreements or licences. The junta has nonetheless strengthened security cooperation with Russia alongside similar shifts in Mali and Burkina Faso, where military regimes have also pivoted away from Western partners.

Renewed uncertainty around Niger’s uranium sector comes at a time when global uranium prices have risen sharply due to new nuclear-power commitments in Asia, Europe and North America. The real market impact depends on production continuity at Somair—conditions that have not been independently verified since the nationalisation in June.

Niger’s move further underscores the decline of regional influence by the regional bloc ECOWAS, whose sanctions and diplomatic pressure failed to reverse the 2023 coup. The announcement signals the junta’s intention to assert sovereign control over strategic mineral exports and to reposition the country’s partnerships outside its traditional alignment with France. Orano has not publicly commented on the latest developments.

A University of Cambridge-led team has analysed giant anaconda fossils from South America to deduce that these tropical snakes reached their maximum size 12.4 million years ago and have remained giants ever since.

Many animal species that lived 12.4 to 5.3 million years ago, in the period known as the ‘Middle to Upper Miocene’, were much bigger than their modern relatives due to warmer global temperatures, extensive wetlands and an abundance of food.

While other Miocene giants - like the 12-metre caiman (Purussaurus) and the 3.2-metre giant freshwater turtle (Stupendemys) - have since gone extinct, anacondas (Eunectes) bucked the trend by surviving as a giant species.

Anacondas are among the largest living snakes in the world. They are usually four to five metres long and in rare cases can reach seven metres.

The team measured 183 fossilised anaconda backbones, representing at least 32 snakes, discovered in Falcón State in Venezuela, South America. Combining these measurements with fossil data from other sites in South America allowed them to calculate that ancient anacondas would have been four to five metres long. This matches the size of anacondas that exist today.

The study is published today in the Journal of Vertebrate Paleontology.

“Other species like giant crocodiles and giant turtles have gone extinct since the Miocene, probably due to cooling global temperatures and shrinking habitats, but the giant anacondas have survived - they are super-resilient,” said Andrés Alfonso-Rojas, a PhD student and Gates Cambridge Scholar in the Department of Zoology at the University of Cambridge, lead author of the research.

He added: “By measuring the fossils we found that anacondas evolved a large body size shortly after they appeared in tropical South America around 12.4 million years ago, and their size hasn’t changed since,” said Alfonso-Rojas.

Alfonso-Rojas double-checked his calculations using a second method called ‘ancestral state reconstruction’, using a family tree of snakes as a way to reconstruct the body length of giant anacondas and related species of living snakes including tree boas and rainbow boas. This confirmed that the average body length of anacondas was four to five metres when they first appeared during the Miocene.

Anacondas live in swamps, marshes, and big rivers like the Amazon. In the Miocene the whole of northern South America resembled today’s Amazonian region, and anacondas were much more widespread than they are today. But there is still enough of the right habitat, with the right food like capybaras and fish around, to allow modern anacondas to keep being big.

It was previously thought that anacondas must have been even bigger in the past when it was warmer, because snakes are particularly sensitive to temperature.

Alfonso-Rojas said: “This is a surprising result because we expected to find the ancient anacondas were seven or eight metres long. But we don’t have any evidence of a larger snake from the Miocene when global temperatures were warmer.”

Before this study it wasn’t clear when anacondas evolved to be so big because of a lack of fossil evidence. These snakes can have more than 300 vertebrae in their backbones, and measurements of the size of individual fossilised vertebrae can provide a reliable indication of how long a snake was.

The anaconda fossils used in the study were collected over several seasons of fieldwork by collaborators at the University of Zurich and the Museo Paleontológico de Urumaco in Venezuela.

HONOLULU, Dec. 1, 2025 — One of the many benefits of electric vehicles is that they are much quieter than traditional gasoline-powered vehicles. In some cases, though, they are too quiet. Automakers are required to design their vehicles so they emit sounds at low speeds to alert pedestrians to their presence.

However, aside from some basic regulations regarding volume, automakers are free to choose whatever noise they wish their vehicles to emit. This freedom gives researchers a unique opportunity to design custom sounds to maximize their effectiveness.

Graduate student Mei Suzuki will present her team’s efforts to design custom approach sounds for electric vehicles Monday, Dec. 1, at 2:35 p.m. HST as part of the Sixth Joint Meeting of the Acoustical Society of America and Acoustical Society of Japan, running Dec. 1-5 in Honolulu, Hawaii.

“In our research, we aimed to design approach-informing sounds based on onomatopoeia that [are] evoked by the image of a ‘quiet vehicle,’” said Suzuki. “These stimuli included sounds created based on onomatopoeic sounds and pink noise.”

To test their library of created sounds, the team played them to volunteers, both in a studio and in real road conditions. They then asked the volunteers to rate each based on criteria such as “The sound has a sense of urgency” and “The sound is easy to notice.” The noises were then ranked based on this feedback.

They found the best performer was a version of pink noise — a type of noise dominated by lower-frequency notes.

“The reason this sound stimulus was rated highest was its strong low-frequency components and its similarity to automotive running noise,” said Suzuki.

This low-frequency noise distribution was less susceptible to being drowned out by other sources of ambient noise, which meant that approaching vehicles could be heard clearly by the volunteers in all conditions.

The researchers are planning to introduce similar sounds for electric bicycles, e-scooters, and other small lightweight mobility devices.

“Starting this year, we are conducting research on the sound design of approach warning sounds specifically for micromobility devices,” said Suzuki. “Since research on approach warning sounds for micromobility devices is largely unexplored, we believe this could contribute to reducing collisions involving pedestrians and visually impaired individuals.”
