I have to admit, Sheffield has a perfect blend of town-life and country-life: and this also applies to its history.
 

 Point yourself in one route and you're wrapped in urban trappings, with the whole of the Steel City's industrial heritage pressed around you. But turn in the opposite direction and, in the same amount of time, you can find yourself in the heart of rural Yorkshire and it's own eclectic past.

The winter has truly turned optimistically towards spring. With a bright sun that darted occasionally through the clouds and the ground finally dry, I decided to do what I as of yet haven't managed: walk around the entire circuit of Damflask.
At 3.5 miles long, the fact that I have only gotten half way around the walk before in my life is as much a commentary on bad timing as it is my general level of rubbish fitness. But finally, having pulled on my trusty Converse shoes, I trogged briskly around the whole circuit of the dam in an hour. The scenery is, in a word, beautiful - with a vast polished expanse of water which sweeps in a gentle curve and then peters away into a marsh-like plain of reeds and thin twisted trees. Surrounding the dam is a pathway that briefly breaks into  a road as you cross the bridge, but is otherwise well maintained for a casual stroll and framed by thin strips of woodland and drystone walls that back onto farmland. The dam is a Mecca for British wildlife which has grown relatively tame through exposure to ramblers. Twice on my travels, for example, a little brown mouse has come out of it's home to sniff around my feet. As well as mice there are coots, moor-hens, herons, ducks, robins, blue-tits and other birds, all charmingly close.

While Damflask is a delight for anyone looking for a place to take in some quiet and fresh air, it also serves a very practical purpose. Stretching some 116 acres and filled with a capacity of 1,123.1 gallons it provides running water throughout Sheffield and, in times of drought, beyond. Currently it is owned by Yorkshire Water and in 2000 was opened up to unrestricted access for the local sailing club to use as well as the general public of walkers and fishermen.

Sheffield itself is fed by multiple dams and reservoirs, and Dam Flask's history is tragically tied up in the most infamous dam of them all.

At midnight on the 11th of March in 1864, Dale Dyke Dam's wall cracked and, despite the efforts of the owner - John Gunson - the wall burst, unleashing a torrent of water that destroyed 800 houses and claimed the lives of some 238 people as well as 700 animals. Downhill of the dam was the village of Damflask. The village was typical of the area, with a corn mill, paper mill, wire mill and - of course - a pub, named The Barrel Inn.

The village was in direct threat of the waters of Dale Dyke Dam but, thanks to some life-saving serendipity the majority of the villagers were saved. A young man named Stephenson Fountain had been sent down to Sheffield to fetch a waterworks engineer when the crack was discovered but, on the way, his saddle girth broke. He stopped in Damflask village to repair it and mentioned the crack in the dam uphill. As word spread the villagers decided that the risk was too great and quickly moved themselves and their families to higher ground. Tragically, some did not act: Henry Burkinshaw scoffed at the idea of the danger and remained in bed. He had worked as a navvy in Dale Dyke Dam and reportedly stated that 'There isn't water enough in Yorkshire to burst that dam.' Within the hour the torrent of deadly water crashed down to consume the village and Henry's body was swept away, only to be discovered later half a mile away the next morning. His landlady, Mrs Kirk, and her pets all survived, having evacuated without him. The waters of Dale Dyke Dam completely destroyed the village and, in a twist of irony, it was never rebuilt, instead cleared and the land filled forever with new waters.


The history of  Dale Dyke Dam is firmly etched in the minds and educations of Sheffield residents. If you travel into the town centre, over to the Sheffield University area and up to the Weston Park museum, it has a whole section of it's gallery dedicated to exhibiting the artifacts that were pulled out from the wreckage that the disaster led behind.
Also if you travel on Ecclesall road, make sure to take a step into the General Cemetery. Buried among the slanted graves is the memorial of John Gunn - the site manager of Dale Dyke Dam - who was never able to forgive himself for the disaster. His grave, with sad hope, reads that he is now, finally, 'Removed from all suffering and strife.'

Perhaps Damflask is the most beautiful and fitting monument of all to this tragedy. As I walked around this strip of industrial countryside I was joined by countless people who also soaked up the freedom and the scenery. As well as a curious mouse, there were countless dogs that were delighted by the water. Joggers huffed past those walkers who ambled along to soak in the scenery. Wizened old men and couples sat on the benches and listened to the birds. Fishermen soaked up the quiet and waited for a nibble on their lines. Families rattled prams and children howled in delight as they charged past on push-along scooters down the straight safe paths. While the lost village will forever be at the heart of the dam as a reminder of the tragedy of the disaster, the people who use this beautiful place will walk across its surface as a reminder of the beauty of life that still presses on.

They always say that life will find a way to survive.


At 1.23 am on April 26th 1986 a catastrophic event took place in the wooded marshlands of Chernobyl, Ukraine, that would forever test this assumption. 

A day earlier, at 1am on April 25th, routine testing began on reactor four of the Chernobyl nuclear power plant to see whether the plant's turbines would be able to maintain the cooling of the system in the case of a power outage, until the backup generators could come into use. In order to simulate the circumstances of the power outage, the participating workers shut down many of the safety systems. However, in the middle of the test a high power demand from Kiev (80 miles away) stalled the operation, and it was not recommenced until 11.10pm that same night. After 1am on April 26th a sudden power surge caused the reactor to dangerously malfunction. Without the safety systems in place there was nothing to stop the crisis escalating and within 23 minutes the reactor itself exploded with disastrous results.

The initial death toll of the plant was put at thirty, as several plant workers and emergency rescue personnel were either killed in the blast or succumbed to injury and radiation sickness. However the true extent of the disaster was quickly placed under debate. While the direct death toll was regarded by the UN in 2005 to be as low as 56, the full extent of the effect of the nuclear poison has been under significant debate over the following decades, and the estimations are harrowing. The UN posited that the cancer figures attributed to the radioactive poisoning of Chernobyl were some 4,000, however Greenpeace claimed that some 270,000 cancer cases were attributed to the disaster, resulting in some 93,000 fatalities. This number grew exponentially in the paper 'Chernobyl: Consequences of the Catastrophe for People and the Environment was published by the New York Academy of Sciences' by Dr. Alexey Yablokov, Dr. Alexey Nesterenko,Dr.Vassili Nesterenko and Dr. Janette Sherman. Founded on a research base of some 5,000 separate reports, and making use of records which have been released from official secrecy, they assert that between 1986 and 2004 some 985,000 people died of cancer that was directly caused by the Chernobyl meltdown. The release of the radioactive poisons of Cesium-137, Plutonium, Iodine-131 and Strontium-90 were tracked to spread across the globe. It consumed the Ukraine, Bulgaria, Finland, France,Germany,Greece,Italy,Poland,Sweden and the UK, with some 10% of fallout across eastern Turkey and Central China, and with an additional 5% dropping upon Northern Africa. It is thought that the radiation from the disaster was 100 times more powerful than the atomic bombs dropped on Hiroshima and Nagasaki.


These figures are, and always will be, under furious debate. 

 Historically, the records and crisis-management of Chernobyl were tempered by the politics of the still chilly Cold War. Attempts at secrecy meant that the full extent of the disaster was not discovered until the Swedish Forsmark nuclear power plant in Stockholm registered unusually high radiation levels. When other nuclear plants across the world had similar readings they contacted the Soviet Union, who denied all knowledge about the disaster until 9pm on April 28th. 
Even now, the admission of the extent of the disastor is one that brings a very heavy political burden, and therefore it is debatable how much still remains in secrecy, and how far studies are potentially manipulated to serve these motivations. Nuclear power offers an efficient alternative to the world's fossil-fuel energy crisis, and has the potential to work with far greater power and efficiency than it's greener options. The greatest fear of Nuclear power comes in the wake of the Chernobyl disaster, and with the recent Fukushima disaster this fear has been reinforced as history is repeated. The public and policy makers must weigh up whether the scale of nuclear disaster balances with the scale of energy advantages for the future. The tenuousness of this balance will always make this a very controversial subject indeed.

The Soviets began trying to clear up the disaster in secrecy. It took nearly two weeks to put out the fires. Pipyat, the nearby town that housed the workers and their families, was evacuated on April 27th, but the rest of the population were only advised to stay indoors and were not evacuated until almost a week later. Chernobyl was sectioned off into various 'exclusion zones' which were chosen based on the measurement of radiation in those zones, and which still remain to this day. Now, over 25 years later, some of the outer zones are being declared suitable for tourism and limited settlement. The burning, burying and containment of radioactive materials began soon after the blast  and the reactor itself was contained in a concrete 'sarcophagus' which, by 1997, leaked. In 2013, the 'New Safe Confinement' sarcophagus was being built to replace the damaged container.

The eyes of the world are still firmly on Chernobyl's exclusion zone, and work is continually being undertaken to manage the damage done and create a place that, while perhaps never 100% safe, can be of use to future generations. Unique in it's scale and infamy, Chernobyl can teach us some valuable lessons.



One fascinating lesson is the growth of ecological diversity in the exclusion zone: the 'Wildlife Park' of Chernobyl.

Amongst the forest and marshland of the exclusion zone, despite the radiation, there seems to be impressive ecological recovery. Amongst the ghost town of Pipyat and even around the reactor itself, bears, wild boar, wolves, deer, wild horses and even rare animals such as eagle owls and even Lynxes have been spotted. In the irradiated pond that acts as a cooling system for the reactors there are teams of fish, including catfish grown large and thriving through a lack of predators.
The Przewalski wild horses, which had escaped from captivity to be introduced into the quarantined area seem to also thrive, growing in number from 21 to 64. It seems that without human occupation Chernobyl can act as a niche for animals to prosper, and for rare animals to gain an ecological foothold once again. The disaster erased much of the invertebrates from the area, and 20-40% of all pine trees died to create the 'Red Forest'. Yet certain types of plant seem to be impressively resistant to radiation damage. Soy beans which grew near the reactor, for example, were studied in 2009 and showed remarkable adaptation in order to protect themselves against radiation. Could it be that through radioactive disaster, we have inadvertently created an Eden that is so rarely seen on this planet: where humans cannot settle and intrude on a natural habitat for wildlife?

Like everything about Chernobyl, this topic is cause for further controversy. For every radiation-resistant soy bean there are examples of wheat and pine trees, both of which show severe mutation in the wake of radiation, even 25 years later. In the wired article Is Chernobyl a Wild Kingdom or a Radioactive Den of Decay? Adam Higginbothan examines both sides of this ecological argument.
For many, the notion of a 'wildlife park' is a false optimism created by misinterpreting the ecological data. The main proponents of this view are Møller and Mousseau who, in 2005, did a chemical study on the feathers of barn swallows captured in the Ukraine and Denmark in order to track their winter migration. While optimists point to the Przewalski horses' population growth, it seems that the barn swallows paint a more pessimistic picture of ecological diversity that is likely to apply to many species of animals across the exclusion zone. Instead of the swallow population sustaining itself over time through successful breeding, when compared to pre-1986 population data, it seems that greater numbers of swallows were coming into the zone for the summer from elsewhere. The area was a population 'sink', absorbing more individuals than it produced. They also argued that this was shown clearly at work in various deformities in the 7,700 individual swallows that they recorded. They pointed to dead and deformed sperm within the birds and outward mutations such as deformed beaks, eyes and toes, tumors, and malformed tails.

The scientific analysis and debate about the 'wildlife park' of Chernobyl have far reaching consequences, as a study of animals gives many clues about how humans may have reacted and will react in future to the radiation that still affects us over 25 years later. For example, in addition to the noted cancer cases that are directly attributed to Chernobyl, in West Berlin, Germany, the prevalance of Downs Syndrome was seen to peak 9 months after the main fallout. Bteween 1980 and 1986 the prevalence of Downs Syndorome was quite normal (1.39-1.59 per 1,000 births) But in 1987 46 cases cases were diagnosed (2.11 per 1,000 births), especially found in a cluster of 27 cases around January 1987. The next year, the prevalanece was back down to 1.77 and by 1989 it reached pre-Chernobyl values.

Just as the animals move back into the exclusion zone, so too do humans choose to reoccupy Chernobyl. 

Starving Ukranians often illegally hunt the animals there, thereby linking themselves to the radioactive food chain. The issue of this impact is even more relevant as illegal 'self settlers' defied authorities to return to their former homes and continue to live in the exclusion zone.
To this day, there are around 130 people who are now settled in the exclusion zone out of an original 1,200 people. Almost all women in their 70s and 80s, their husbands having died off from alcoholism, overuse of cigarettes or radiation effects. These 'Babushkas of Chernobyl' feature in a documentary by Holly Morris, where one self-settler Hannah Zavorotnya explains how she snuck back into her village in 1986, defying the soldiers and refusing to leave her home. So long as they were beyond child-bearing age, these people were permitted to stay, and it seems that - despite the dangers - doing so has been beneficial to them. Many old people who were relocated from their homes at Chernobyl suffered relocation trauma, as they were pushed from their links to rural lands in their home and into urban tower blocks. Acoording to studies these women have outlived their relocated counterparts, on average by up to 10 years. "If you leave you die." Holly reports the Babushkas telling her. "Those who left are worse off now. They are all dying of sadness." "Motherland is Motherland. I will never leave."




In conclusion, what is clear from Chernobyl is that it is a place of contrasts, and that it is far from a nuclear wasteland. 

Chernobyl's legacy will live on for hundreds of years: physically in it's radiation as it continues to affect the world, and in the lives of the animal and human populations that settle there, and emotionally through its displaced peoples and the policies of the governments that turn their eyes to it. What Chernobyl's wildlife park and its Babushkas show us is that, even in all of this difficulty and hardship, and in this uncertainty for the future, life will find a way.


Chernobyl is, of course, still in living memory. If you can remember the disaster I would love to hear your thoughts. Please feel free to leave a message in the comments.
