Diocletian's Palace, A New Look

Published in Environment

The Romans knew how to build, and they knew how to choose the best sites for their building. Diocletian's Palace in Split is a prime and well-preserved example. New discoveries in and around the Palace in recent years have brought about a major revision of the history of this magnificent Late Antique building project.

Split is the chief mainland portin central Dalmatia, and Hvar islanders gravitate to it for shopping, cultural events, hospital visits, complicated bureaucratic affairs and lawsuits. Split is also the gateway to other parts of Croatia and the world. Locals by and large take for granted the historical treasures of the city environment, which for centuries were ignored, destroyed or allowed to decay. In modern times, however, major archaeological investigations have been unfolding quietly alongside renovations, under the aegis of the Ministry of Culture Conservation Office in Split.


Diocletian’s Palace forms the heart of modern-day Split, the main city in Croatia’s coastal region of Dalmatia. Considered a particularly fine example of the preservation of buildings through succeeding historical periods, the historical complex based on Diocletian’s Palace was inscribed in the UNESCO World Heritage List in 1979.

For centuries, it was thought that the Emperor Diocletian (c. 245 - c. 316 CE) planned and built his splendid palace in Aspalathos (also known as Spalatum) as a residence for his retirement, in which he could enjoy a peaceful life pottering about in his kitchen garden growing prized cabbages. This view coloured the interpretation of the surviving elements of the Palace buildings.

The assumption seemed reasonable for many reasons. The Palace was more or less completed in 305 CE, the same year in which Diocletian abdicated. There are no known written records about the palace’s concept, design and construction. Much of it was subsumed into a hotch-potch of dwellings as people fleeing marauders during succeeding centuries moved into the safety of its walls. The Palace’s pagan artefacts and symbols were mostly dispersed or destroyed after the temples were converted for Christian use. Significant parts remained of the core of Palace buildings, walls and towers, but there was virtually no trace of Diocletian having built anything outside its enclosures.

In the absence of written sources, knowledge about the Palace depended on an analysis of what remained to be seen above ground, and what could be uncovered through excavation. The narrow streets make renovation and conservation works extremely complicated. A further difficulty is striking a balance between preserving relics from the past and allowing property owners to use or develop their land or buildings which turn out to be historically significant. As Split is a thriving city, many finds have come about by chance during the construction of modern buildings.


Historians and archaeologists have argued for many years about the correct designation for the Palace, because there was so little evidence about the use of its various parts, especially in the northern section, and it appeared to lack some of the attributes of ‘genuine’ imperial palaces such as those in Antioch and Constantinople. Should it be called a palace (palatium), military camp (castrum), a country estate (villa) or some other name?

Many early writers referred to it as a villa. It was not unknown for Roman Emperors to build themselves extended private estates which were termed ‘villas’. The Emperor Hadrian (76 - 138 CE), who reigned from 117 to 138 CE, built himself an extravagant complex with over 30 buildings at Tibur, modern-day Tivoli, 29 km from Rome, then capital of the Roman Empire. Apart from the imperial palace for the Emperor and residential buildings for his courtiers, Hadrian’s Villa contained several temples, state rooms, baths (thermae), libraries, a theatre and a mausoleum, among many other facilities.

‘Diocletian’s Palace’ has for centuries been the accepted term for the whole complex within the fortifying walls. It consisted of three main sections: the northern part, whose functions have not been established; the southern part, which we refer to as the Imperial Quarters; and the Temenos or temple enclosure between the two.


Born in Dalmatia and originally called Diocles, Diocletian was a man of humble origins. He rose to success as a military man, and became Emperor by army acclaim in 284 CE, following the deaths of the Emperor Carus and his son Numerian.

He adopted the names Gaius Aurelius Valerius Diocletianus when he became Emperor. Besides the title Augustus, he was  Sol invictus (the Unvanquished Sun) and Diocletianus Jovius (Diocletian Son of Jove / Jupiter, who was, of course, King of the Gods in Roman times).

In November 285 CE, Diocletian divided the Empire into East and West sections, and appointed his military comrade Aurelius Maximianus as Caesar in the Western Empire. In 293 CE, Diocletian established the Tetrarchy. Now there were two Augusti, and they kept power in the family by appointing their sons-in-law as their deputy Caesars. Each Tetrarch had his own administration and capital city.

Of the eight Roman Emperors before Diocletian, all are thought to have been assassinated, often by their own guards, four of them dying within a year of assuming power. Diocletian took great trouble to protect himself, and did not allow any armed personnel close to him.

Diocletian was clearly a man of determination, discipline and order, a ruthless military leader who used his powers to the full. He evidently inspired loyalty, and was prepared to trust those who had proved their worth. He was apparently devoted to his wife Prisca and daughter Valeria, unusually so for a Roman Emperor. He was practical, a man of action and politics as well as show. He travelled almost incessantly around the Empire throughout his reign. Apart from taking part in extensive military campaigns, he introduced monetary reforms and a more unified taxation system, to finance both his army and his ambitious building programmes. He increased the number of provinces in the empire, and created a new tier of local government with twelve so-called dioceses, each comprising several provinces. In the interests of political stability, he guaranteed bread for all Roman citizens, as well as spectacular shows and games.

In Diocletian’s view, traditional Roman religious practices were vital for maintaining unity and order in the Empire. He and his co-Emperors restored and built numerous temples throughout the Empire, reviving and following the ancient Roman traditions. He was savage against perceived threats: once persuaded that newer mystical religions could undermine political stability, he ordered the persecution of everyone who refused to sacrifice to the Roman gods, resulting in the relentless persecution of Manichaeans (from about 302 CE) and Christians (from 303 CE).

Diocletian asserted his authority on every level. His seniority over his co-emperor was defined through Maximian’s designation as Herculius, (son of Hercules), Hercules being the son of Jupiter in the hierarchy of the gods. Diocletian introduced a strict protocol of etiquette to his court, where visitors had to prostrate themselves before the Emperor and kiss his purple robe. The distance he created between himself and his subjects was both for his safety and to reinforce his supreme and divine status.


Although the Tetrarchy was designed to ensure a peaceful succession after the reign of the two Augusti, there is no evidence that Diocletian foresaw, let alone planned the eventuality of retirement before being compelled to by illness in 304. Diocletian was the first Roman Emperor ever to abdicate, and no other Emperor had outlived his reign, so there was no precedent for retirement.

The building of the Palace in Aspalathos started in about 295 CE, when Diocletian was very much in power. Aspalathos was some six kilometres from Salona, capital of the Province of Dalmatia, and was also convenient for the transport of stone from the stoneworks near the port of Splitska on Brač Island.

This Palace was by no means the only major building project in the Empire during the years before Diocletian’s abdication. All the Tetrarchs established centres with palaces, and Diocletian himself conducted an extensive building programme in different parts of the empire. Contemporary writer Lactantius described him as having a lust for building (‘cupiditas aedificandi’).

It was only when he fell ill during a tour of the Danubian territories in the summer of 304 CE that Diocletian’s ability to rule was undermined. He abdicated on May 1st 305 CE, simultaneously with a reluctant Maximian. By this time the Palace at Aspalathos was evidently ready for habitation, and Diocletian retired to his native land. Even after his abdication, he continued to advise his successors. He was invited to return to power in 308 CE, but refused on the grounds that growing vegetables successfully was more satisfying than being Emperor, as reported by Aurelius Victor in 361 CE: “Utinam Salonae possetis visere olera nostris manibus instituta, profecto numquam istud temptandum iudicaretis”.

Diocletian had reigned as an autocrat, despite spreading some of the administrative burden among his trusted co-emperors. Although he reverted to his original name of Diocles, he took on the title of Senior Augustus on abdicating, and retained the titles of Jovius and Sol invictus. Thus he renounced the everyday responsibilities of earthly power, but kept the aspects of divinity which he had assumed on becoming Emperor.


Salona, as capital of the Roman Province of Dalmatia, was supplied with water via an aqueduct with its source in the spring of the Jadro River. Built during the reign of the Emperor Augustus (27 BCE - 14 CE), the aqueduct was 3.850 km long and channelled up to 12,000 m3 of water per day. Diocletian enlarged and extended the aqueduct to supply up to 129,600 m3 per day. Thus Aspalathos had a bigger water supply than Salona, which at the time had a population of about 60,000.


One of the few certainties about Aspalathos in Diocletian’s day is that it contained textile works, as the office of textile works manager, ‘Procurator gynaecii Iovensis Dalmatiae - Aspalato’, is listed in ‘Notitia Dignitatum’, a comprehensive document listing Roman officials and their administrative offices up to the late 4th and 5th centuries.

Textile production was extremely profitable, and Diocletian made the whole purple dyeing industry a state monopoly. There were numerous textile production and cloth dyeing facilities around the Empire, including at Salona.

A lot of water was needed in textile production. Aspalathos was close to a river, which, together with the extended aqueduct, meant that water was plentiful. Sulphur was used in the bleaching process, and Aspalathos had sulphur springs, near the present-day fish market. These might have been among the reasons for Diocletian choosing Aspalathos for his Palace.


Excavations at two sites outside the Palace walls have shown that Diocletian’s building project at Aspalathos was more wide-ranging than previously thought.

The Amphitheatre

In 2013 digging for a new shopping mall to the north of the Palace revealed the outline of part of a Roman amphitheatre with a span of 50 metres dating to the early 4th century CE. The aqueduct was found to have skirted round the eastern stands, proving that the two structures were planned and built in tandem. The remnants of stands were found in previous excavations, but were thought to belong to a theatre or odeon. The latest investigations have shown beyond doubt that they were part of an amphitheatre.

Outisde the amphitheatre, excavations uncovered Christian sarcophagi. It is thought that the two Christian churches found nearby were so-called martyrs' churches, established sometime after Diocletian's reign.

The Riva

Along the western half of the waterfront (riva) south of the Palace, excavations in 2006 and 2007 showed that the south wall was not built directly on the waterfront, as previously thought. The popular image by Ernest Hébrard portraying the Palace as a Villa Marittima is incorrect. In fact, there was a wall from before Diocletian’s time just over 12 metres away from the Palace’s south facade, and a thick layer of concrete dating to Diocletian’s time which extended along the waterfront to a length of about 180 metres, which is roughly a stadion (unit of measurement). The sea level in Diocletian’s time was nearly two metres lower than now, so the concrete structure would have been above the water.

How far the concrete structure extended southwards towards the sea is not known. It may have been a stadium: the lower part of the Palace’s south wall contained no openings apart from the modest doorway, so it is possible that spectator stands were banked against it. The majestic Serlian windows in the upper part of the south wall, which were only accessible from the Imperial Quarters, suggest that they were viewing points for important events in the space below on the seafront. (The central window, which was reached through a portico in line with the Porta Aurea, is now walled up.)

Whatever was in front of the Palace, the findings tend to confirm that the length of the south wall, in differing from the north wall, was no error. Following the excavations the seafront was paved over, covering all trace of the Antique structures. Plans are in hand to excavate the eastern half of the waterfront.


It took several centuries for historians and travellers to take an interest in Diocletian’s Palace, by which time much of its detail had been altered beyond recognition. Attention was concentrated on the compact area inside the massive walls which defined the Palace.

The walls formed a trapezium, not a rectangle. Nor was the alignment of the Palace as one would expect: it did not follow the centuriation of the ager salonitanus. The site required a lot of preparation, especially in view of the sharp slope downwards on its south side. It was not chosen arbitrarily.


The north wall measured 174.74 metres, the south wall 181.65 metres, the west wall was over 200 metres, with the east wall slightly longer. The walls on the three landward sides had sentry pathways, while the south wall overlooking the sea did not. The internal space was divided by the main streets, the cardo running north-south from the main gate, known as the Porta Aurea (Golden Gate), and the east-west decumanus linking the Porta Argentea (Silver Gate) with the Porta Ferrea (Iron Gate). On the south side towards the sea, at the level of the Basement or Cellars (Podrumi), there was, and still is, an entrance which was modest by comparison with the others. This is commonly referred to as the Porta Aenea (Bronze Gate), which is probably incorrect. It was clearly a kind of service entrance.

The Porta Aurea, which was the main entrance leading directly from the Salona - Aspalathos road into the Palace, was ornate and grand, with strong double doors. It had five niches above the gate on its outer side, which probably contained statues of the Tetrarchs, perhaps with a representation of Jupiter or Apollo in the centre. The designation of metals for each entrance, if it is correct, usually referred to historical eras. The golden age was a time of peace and plenty characterized by olives and beehives.

Both main streets were some 12 metres wide, and originally had covered walkways to either side. Buildings now encroach on them in great part. An imposing colonnade flanked the southern part of the cardo, as it does to this day. This was known as the Peristylium in Robert Adam’s time in the 18th century, today as the Peristyle. The Palace Peristyle was more of a forum or gathering-place than a street. It is generally accepted that the cardo as a thoroughfare ended where it met the decumanus.


Under the southern section of the Palace the ground sloped away. An extensive series of archways and galleries  known as the Basement supported the structures above. The Basement was rectangular, by contrast with the trapezium above it. It is thought that one possible explanation for the asymmetry was the need to preserve previous sacral sites, of which some remnants have been discovered in the Imperial Residence in the eastern part of the Imperial Quarters.

The Basement layout has given some clues as to the layout of rooms above. Diocletian’s private residence had winter and summer rooms built on either side of a dining area (Triclinium). Imperial baths (thermae) have been discovered  on the western side. There was a large hall in the centre of the southern area, which has been termed an aula or salutatorium. Between the Aula and the thermae was a room which may have been a Consilium Sacrum.


Dominating the centre of the end of the cardo was the Protiron, a rectangular lobby supported on four massive red granite columns. The Emperor’s processional path (adventus) led from the Porta Aurea along the cardo and Peristyle to culminate at the Protiron. The Protiron was a grand setting where Diocletian could stand to receive homage from the people gathered in the Peristyle below. It was comprehensively restored between 2004 and 2012.


At the crossroads of the two main streets, excavations under the original Roman paving revealed a base construction measuring 12.36m by 12.36m, with a cruciform ground plan and four foundations in the corners. During excavations in 1959 - 1960, it was thought to be the placement for a groma for accurate alignment. The discovery of the true extent of the foundations, which filled the whole space of the cardo-decumanus intersection, suggested that they could be the base for a Tetrakionion or Tetrapylon, whose purpose was to create an imposing entrance to a sacral area, symbolically marking a transition from the earthly domain to the territory of the gods. In the photograph below, Radoslav Bužančić indicates where one part of the support structure was sited, under the present-day stone pavement.

The base contained an equidistant cross formed by pebbles set in a hard mortar at its centre. Symbolically, the isosceles cross represented the unification of the material and ethereal worlds. The cross was paved over in Diocletian’s time, as it is today, but it would have been a significant symbol on the threshold of the entrance to the sacred area of the Palace.


On either side of the Peristyle were temples in the sacral area (Temenos) enclosed by walls. The Temenos was separated from the Imperial Quarters by a trench, a common safety precaution in Roman times, especially against fire. The entrance to the sacred area on either side of the Peristyle was marked by four red granite columns, matching those of the Protiron.

Only two temples were still visible by the 16th century. Evidently there had been more: Thomas the Archdeacon in the 13th century described three temples, dedicated to Jupiter, Aesculapius and Mars, while in the 16th century Antonio Proculiano stated that there were four, dedicated to Janus, Cybele, Venus and Jupiter.

Inevitably, there is confusion about which god or gods each  temple might have been dedicated to. In particular the rectangular temple in the west of the Temenos (now the Baptistery) is often referred to as Jupiter’s, although it is more generally accepted that the Mausoleum to the east (now the Cathedral of St. Doimus) was the Temple of Jupiter.

The Small Temple

The shapes of the temples were significant. To the Romans, the square shape symbolized the earth realm. The four sides represented the four seasons and directions, also the sun’s phases of two solstices and two equinoxes.

It is feasible that the rectangular western temple was dedicated to Janus, the god with two faces who represented beginnings and transition, and was the guardian of gates and doors. In the absence of certain proof, the term ‘Small Temple’ is often used, even though this was possibly not the smallest temple of the four. It has retained its original intricate carvings around the doorway and the top of the walls externally, and internally the coffered barrel-vaulted ceiling which enclosed the cella.

The Temples of Cybele and Venus

The remains of a small round temple to the west of the Peristyle, opposite the Mausoleum, were first uncovered by chance in 1851 by Vicko Andrić, Split’s first Conservator, during digging for a drainage channel. The discovery was evidently considered unimportant, as it was not mentioned again in academic studies for over one hundred years, when it resurfaced during excavations led by Jerko Marasović in 1957. Parts of a coffered ceiling were found, and these are now on display in front of a restored part of the temple wall on the refurbished ground floor of the Skočibučić-Lukaris Palace, which opened as an exhibition gallery in 2014. The crypt of the temple, which was filled with water sometime during the past centuries, is still under exploration.

This round temple is known as the Temple of Cybele, although there is no definitive proof that this attribution is correct. Cybele was originally a mother goddess in Anatolia. The Romans revered her as the Magna Mater (Great Mother), and she was considered a goddess of protection. In ancient times the circle represented perfection and the heavenly sphere, as well as the cyclic movement of perpetual renewal.

The 1957 excavations in the western Temenos also revealed the remnants of a second small round temple, north of the Temple of Cybele. This was attributed to Venus, who was also considered a mother to the Roman people. She represented love, sensuality and sexuality. Part of the floor of this temple is preserved in the present-day cafe Luxor on the west side of the Peristyle.

The Mausoleum, Temple of Jupiter

The best-preserved of the four temples is the Mausoleum, which was certainly planned as the resting place for Diocletian and Prisca’s remains. At the entrance to the Mausoleum there was at least one sphinx, which was described as an image of Cybele, bearing on its head a pillar topped by a statue of Jupiter. It is not known which direction the sphinx(es) faced.

Most of the pagan artefacts, including Diocletian’s sarcophagus, were removed by the time the temple was converted into the Christian Cathedral in the 7th century CE. The building still has its original pillars and carved capitals, and most of the original frieze around the upper segment of the walls. The cupola of the Mausoleum remains, but without its mosaics. Parts of a black and white checkered floor were uncovered in front of the side altar to St. Anastasius. At first this was thought to be the original Roman floor, but further digging revealed that it dated to the founding of the Cathedral in the 7th century CE.

The original Roman floor consisted of large stone slabs, which were probably re-used in later construction works.

More of the 7th century stone floor has been uncovered, bit by bit.

Where there is now a window disrupting the centre of the frieze on the east wall opposite the door, there would have been an image, possibly that of Jupiter or Sol Invictus. To the right of this is a relief of Diocletian, to the left one of his wife Prisca. In the central medallion of the frieze on the west wall is a head, thought to be of Hermes Psychopompus or Mercury, the god of transitions, among other things, who helped humans to cross the boundary into the other world when they died. As Son of Jupiter, Diocletian expected to be raised up into apotheosis after his death, and the decoration of the Mausoleum was designed accordingly.

The Mausoleum was constructed on an octagonal base, topped by a dome. The octagon symbolized the transition from earth to heaven, with the eight points representing the solstices, equinoxes, seasons and cardinal and intermediate directions. The present octagonal roof is a later addition. When the Mausoleum roof was renovated, laser investigations showed that the original cupola had been lower and rounder with a circular opening (oculus) at its centre. The open oculus would have allowed the sun to play over certain parts of the Temple, particularly over the images in the frieze and probably over the space designated for Diocletian’s sarcophagus.

The significance of sunlight shining through an oculus has been demonstrated in the Villa Adriana at Tivoli and the Pantheon in Rome in recent years. As the oculus was such an important feature in the symbolic link between earth and the heavenly sun, it is likely that at least one of the round temples in Diocletian's temenos was also open to the sky.


The one structure in the Palace which has retained the open oculus in its dome is the Vestibule. This structure stood behind the Protiron, in line with the Peristyle and the Porta Aurea.

The function of the Vestibule has not been established. It is generally considered to have been a kind of lobby, leading into the Aula or Salutatorium. It had a circular ground plan, and was enclosed at ground floor level by square walls. Cylindrical structures in the spaces to the sides of the northern doorway, between the rounded sides of the Vestibule and the squared enclosing walls, suggest that there may have been machinery, probably water-operated, to open and close heavy doors. These would probably have been bronze, constituting the Porta Aenea. Bronze represented Mars, the god of war, and victory over enemies. It is possible that these doors formed an ‘ad Calchi’, as in the Palaces in Ravenna and Constantinople, a term connected with the cult of the Emperor trampling on his subjects to make them well, or trampling on his enemies to subdue them.

The Vestibule was richly decorated with mosaics, fragments of which have been found. The interior of the dome was described as shimmering in gold by Marko Marulić (1450 - 1524), who referred to it as a fifth temple. In 2003 and 2004, Mladen Pejaković demonstrated the play of the sun’s rays over the interior of the central northern niches during the solstices and equinoxes, leaving no doubt that the building had a significant symbolic role, and was not roofed over.


The Palace at Aspalathos was carefully designed to combine the earthly and the spiritual. While the northern section was probably planned for practical activities including administration, the southern part comprising the Temenos and Imperial Quarters formed a hallowed sanctuary where the gods were revered alongside Diocletian the demi-god.

The structures of the Palace are imbued with symbolism relating to the gods. Specific use was made of the effects of the sun’s rays. The temples in the sacral area were designed as an image of the pathway from earth to heaven, with special emphasis on the Emperor’s destiny to take his place among the gods after death. It is perhaps ironical, or perhaps just, that after his death Diocletian’s Mausoleum became a shrine to St. Doimus, and its Crypt to St. Lucy, two Christians martyred in his purges.

Diocletian only enjoyed living in his Palace for some ten years. Even his remains were not allowed to remain in their allotted place. As he had no heirs, his personal connexion with the Palace ended with their removal. But a significant part of his creation has endured for centuries as a kind of monument imbued with many of its founder’s characteristics. Its defensive walls have never been forcibly penetrated by an enemy. Some old Split families, such as Skočibučić-Lukaris, Grisogono and Cipci, have been resident within the central part of the Palace for several centuries.

Historians, archaeologists and tens of thousands of tourists have found much to wonder at in the old structures. Little by little, the Palace’s deeper meaning and true purpose are being revealed, putting paid to the long-held image that it was planned as a luxurious retirement home for a humble retired emperor quietly tending his vegetable patches.

  • Report looks at 16 conflict areas and calls for military to stop targeting water resources

    Diarrhoea and other diseases related to poor sanitation are bigger killers of children in areas of conflict than violence and war itself, a report has found, highlighting the need for improved infrastructure as a way of helping civilian populations afflicted by warfare.

    Children under five are more than 20 times more likely to die from diarrhoeal diseases than from direct violence, according to Unicef. Henrietta Fore, the organisation’s executive director, said: “The reality is there are more children who die from lack of access to safe water than by bullets.”

It also says the UK is not ending unsustainable fishing; stopping the arrival of invasive alien species; nor raising public awareness of the importance of biodiversity.

  • The ‘Dieselgate’ scandal was suppressed for years – while we should have been driving electric cars. By Beth Gardiner

    John German had not been looking to make a splash when he commissioned an examination of pollution from diesel cars back in 2013. The exam compared what came out of their exhaust pipes, during the lab tests that were required by law, with emissions on the road under real driving conditions. German and his colleagues at the International Council on Clean Transportation (ICCT) in the US just wanted to tie up the last loose ends in a big report, and thought the research would give them something positive to say about diesel. They might even be able to offer tips to Europe from the US’s experience in getting the dirty fuel to run a little cleaner.

    But that was not how it turned out. They chose a Volkswagen Jetta as their first test subject, and a VW Passat next. Regulators in California agreed to do the routine certification test for them, and the council hired researchers from West Virginia University to then drive the same cars through cities, along highways and into the mountains, using equipment that tests emissions straight from the cars’ exhausts.

  • Rob Stewart’s followup to his 2006 feature shines a light on human cruelty – and gains power from the fate of its maker

    In the 2006 eco-doc Sharkwater, Canadian activist film-maker Rob Stewart gave us a heartfelt plea to save the planet’s sharks. He was on a mission to reduce overfishing and rehabilitate the creatures’ reputation as stone-cold killers – if only we could love sharks as much as we love cuddly pandas we’d do more to protect them. Back then, you couldn’t help feeling that Stewart wanted us to love him too, with all the shots of himself in tiny Speedos. Watching the sequel, I experienced a sharp stab of self-reproach. Stewart died in a diving accident while shooting this film – he was 37. Sharkwater: Extinction has been scrappily put together from footage he’d already shot.

    And there are some striking images here. Since the first film, many countries have banned “finning” ­– the practice of hacking off the fins then tossing the shark’s body back into the sea. But it still happens. In Costa Rica, Stewart uses a drone to film a warehouse packed with them. Shark fin soup is a delicacy in China, which drives the illegal market. And it’s not just finning that’s the problem. In California, he captures upsetting footage of a graceful thresher shark tangled up in a mile-long net intended for swordfish.

  • World Water Day study highlights lethal nature of unsafe sanitation and hygiene for children, especially under-fives

    Children under five who live in conflict zones are 20 times more likely to die from diarrhoeal diseases linked to unsafe water than from direct violence as a result of war, Unicef has found.

    Analysing mortality data from 16 countries beset by long-term conflict – including Afghanistan, Iraq, Syria and Yemen – the UN children’s agency also found that unsafe water, sanitation and hygiene kills nearly three times more children under 15 than war.

  • Science agency says scourge of wandering trad could be slowed by fungus, which they have called its ‘natural pathogen’

    Australia’s national science agency will release a Brazilian leaf smut fungus to target and kill an invasive weed that covers large parts of the continent’s east coast.

    Researchers from the CSIRO say the scourge of wandering trad could be slowed by the introduction of the Kordyana brasiliensis fungus, which they have called its “natural pathogen”.

  • While the ultimate goal is to stop plastics from entering the water in the first place, cleanup projects play an important role

    Somewhere in Hilo, on Hawaii’s Big Island, a team of scientists and engineers are tending to The Ocean Cleanup’s 600-metre-long rubbish-herding device, after its maiden voyage to the Great Pacific garbage patch was cut short in December 2018, because it fractured into two pieces.

    The project has had its fair share of problems since it was unveiled in May 2017 and has been criticised by marine scientists and environmental groups for its potential negative environmental impact. However, some still herald The Ocean Cleanup for having a positive effect on plastic pollution.

  • The latest study warning us to eat less meat has brought angry sceptics out in droves. But who should we believe?

    Sometimes, particularly when looking at the weekend newspapers, it can seem that our obsession with food and health has reached a pitch of pure hysteria. “Eat!” screams one headline. “Diet!” shouts another. Cut out carbohydrates, suggests one report. Carbs are good for you, says a different one. Lower your fat intake. No, fat’s healthy, sugar’s the problem. Coffee raises the risk of heart disease. But it lowers the risk of diabetes. And so on, until you just want to ditch the papers and watch The Great British Bake Off or MasterChef.

    Food, how to cook it, what it does to you and what growing or rearing it does to the planet are issues that crowd the media. And yet, as the clamour grows, clarity recedes. An estimated 820 million people went hungry last year, according to the UN Food and Agriculture Organisation. A third of all people were vitamin-deficient. Two billion were classified as overweight and 600 million as obese. It’s also estimated that 1bn tonnes of food are wasted every year – a third of the total produced. A plethora of academic reports concerning food consumption and production have been published in recent years. The latest and arguably the most far-reaching is Food in the Anthropocene:the Eat-Lancet Commission on healthy diets from sustainable food systems, which was conducted over three years by 37 senior scientists from around the world and published earlier this year.

  • Scientists say a drastic cut in meat consumption is needed, but this requires political will

    It has been known for a while that the amount of animal products being eaten is bad for both the welfare of animals and the environment. People cannot consume 12.9bn eggs in the UK each year without breaking a few.

    But the extent of the damage, and the amount by which people need to cut back, is now becoming clearer. On Wednesday, the Lancet medical journal published a study that calls for dramatic changes to food production and the human diet, in order to avoid “catastrophic damage to the planet”.

  • The continent’s largest land mammal plays crucial role in spiritual lives of the tribes

    On 5,000 hectares of unploughed prairie in north-eastern Montana, hundreds of wild bison roam once again. But this herd is not in a national park or a protected sanctuary – they are on tribal lands. Belonging to the Assiniboine and Sioux tribes of Fort Peck Reservation, the 340 bison is the largest conservation herd in the ongoing bison restoration efforts by North America’s Indigenous people.

    The bison – or as Native Americans call them, buffalo – are not just “sustenance,” according to Leroy Little Bear, a professor at the University of Lethbridge and a leader in the bison restoration efforts with the Blood Tribe. The continent’s largest land mammal plays a major role in the spiritual and cultural lives of numerous Native American tribes, an “integrated relationship,” he said.
