Straw homes are a cheap and green fix for the housing crisis





The UK construction sector must reduce its energy consumption by 50% and its carbon emissions by 80% by 2050.

So radical changes are needed to the way we approach building houses. Straw could be a critical part of the transition towards a low-carbon future.

The thermal insulation value of a typical straw bale wall meets the requirements of even the most demanding performance specifications.

Recent research led by the BRE Centre for Innovative Construction Materials at the University of Bath has shown that straw bale buildings reduce energy bills by 90% compared to conventional housing stock.

The manufacture of cement, used in concrete, is responsible alone for up to 8% of all industrially produced greenhouse gas emissions. Using natural materials such as straw, often directly from the field and with little further processing, significantly reduces this impact.

Traditionally, the environmental impact of construction materials has been significantly less than the impact of occupation (heating, cooling and so on) over the lifespan of the building. However, in modern energy efficient buildings the proportion attributable to that ’embodied’ in the fabric of the building is expected to increase to at least 90%.

Measures to reduce the impact of the embodied energy and carbon will deliver even more environmentally friendly buildings.

A natural building material

Straw is just the dried stalks of plants stripped of their grain. You don’t really ‘make straw’ – it’s a co-product of grain production, an established and essential agricultural process. So using straw doesn’t displace land required for essential food production.

In the UK more than 7m tonnes of straw remains after the production of wheat, and up to half this amount is effectively discarded due to its low value – simply chopped up and returned to the soil.

As an average three-bedroom house needs 7.2 tonnes of straw, the ‘leftover’ could be used to build more than 500,000 new homes – a city the size of Birmingham could be built each year using discarded straw.

Straw is also a low-cost material. But more importantly, as a plant it captures and stores atmospheric carbon dioxide during photosynthesis. By using more and more straw in buildings we are creating a natural carbon storage bank.

Though the bible references using straw for bricks – and thatched roofs – have been common for centuries, modern straw construction was developed when mechanical baling machines were first used in late 19th-century Nebraska.

Stacked like large bricks, straw bales can be used for modest loadbearing as well as non-loadbearing walls. The oldest surviving straw bale building is around 100 years old.

But straw has never caught on as an alternative to bricks, concrete or timber. There are concerns about its poor durability, fire resistance, the way it attracts mice and rats and, as one of the three little pigs found out the hard way, its lack of structural integrity.

The answer – high precision pre-fabricated ‘bales’

Straw bales aren’t currently made to the same levels of tolerance and specification as bricks or cement. The fact they’re generally slightly different sizes combined with the need to keep bales dry during construction has meant most builders would not, until recently, consider straw bales a viable solution for anything. Other than perhaps for enthusiastic self-builders.

However, the development of prefabricated wall panels using straw bale for insulation has now provided the opportunity to market straw to the mainstream construction industry.

Prefabrication, or off-site manufacture, means that wall panels can be made to a very high specification in a factory, protected from variable weather conditions that would otherwise inhibit on-site building with straw.

A prefabricated product can be certified as fit for use by industry bodies, making it much more acceptable to builders, financiers and insurers. It also radically reduces site construction times, with houses able to be erected in ten weeks instead of around 16 weeks for more conventional buildings. It seems the time has arrived for straw bale construction.

For the past ten years the University of Bath has been working with a local company, ModCell, to develop prefabricated straw bales. We started out looking at straw as a low-carbon cladding solution and soon moved on to developing panels that could bear heavy loads. Now, we are able to make low-energy prefabricated straw bale houses.

 

Bath’s own straw house. The panels from 00:09 onwards are all prefab straw and lime plaster.

Officially approved for the formal construction sector

The panels have been subjected to fire tests, thermal transmittance tests, accelerated weathering tests, acoustic tests, simulated flooding and impact testing. We’ve even tested the structures in a simulated hurricane force wind, in what has been termed the ‘big bad wolf’ test: the panels and prototype BaleHaus passed with flying colours.

These panels have now been granted certification. This in turn means insurers will cover straw houses and home-buyers will be able to obtain mortgages.

Hayesfield School in Bath, EcoDepot in York and the School of Architecture at the University of the West of England have all made use of these panels. Certification means the housing market can now use straw too, with LILAC in Leeds completed in 2013 and now a new development in Bristol due for completion later this year, with proposals for larger schemes already in planning.

Modern prefabricated straw bale houses are affordable, deliver excellent levels of energy efficiency in use for the home-owner or occupier and provide a genuine sustainable solution by using a cheap and widely available agricultural co-product.

Other similar prefabricated systems using straw bale construction have been developed in Australia, Belgium and Canada. Entire communities, towns or even cities built from straw bales. And why not?

1.5 million solar lamps brighten Africa’s future





Many of the 600 million people who are still without electricity in Africa rely on home-made kerosene lamps for lighting – putting themselves in danger from fire, toxic black smoke, and eye damage.

But cheaper solar technology is being offered that can provide long-lasting light and additional power to charge telephones and other electric devices, without the need for an electricity grid connection.

The campaign to eliminate the kerosene lamp was begun by SolarAid, an international charity that seeks to combat poverty and climate change and whose declared goal is to “eradicate the kerosene lamp from Africa by 2020”.

It set up an African network to sell these devices in 2006, with the aim that every kerosene lamp will be replaced with solar power by the end of the decade. So far, with over 1.5 million solar lights sold, about 9 million people have benefited from its scheme.

Saves up to 15% of family income, reduces emissions

The charity says that a solar lamp saves money because buying kerosene or candles uses 10-15% of family income, about $70 per year, whereas a solar kit bought for as little as $10 produces light for more than five years.

The risk of a kerosene fire is also removed, along with the indoor air pollution, and the lamps allow children to study at night. A typical family’s use of kerosene lamps causes emissions of 300kg of carbon dioxide a year – now an easily avoided contribution to climate change.

In 2006 SolarAid set up SunnyMoney, a social enterprise that sells the lights via school networks and local businesses – and has grown to become Africa’s biggest solar lights distributor, while also inspiring dozens of other solar businesses addressing domestic and commercial markets.

Selling the lights, rather than donating them, keeps money in local communities, provides employment, and allows the profits to be ploughed back into extending the scheme.

“One of our main objectives is to catalyse solar markets, so we welcome the competition”, says Susie Wheeldon of Solar Aid. “Together we are all helping to make Africa’s solar revolution happen – and eliminate dirty, dangerous, expensive kerosene lamps!”

In 2009 under 1% of Africa’s population was using modern solar lighting with LEDs, and that figure has now risen to about 5%. SolarAid’s own network grew by 81% from 2013-2014 – a near doubling.

“Our ambition is to develop partnerships, grow our network and ultimately get solar lighting to 100% of the African market. If the solar market doubles every year that will be achieved by 2030 – but we want to go even faster that that and hit the goal a decade earlier”

Currently, the organisation has East Africa networks in Kenya, Malawi, Tanzania, Zambia and Uganda, where over 80% of people have no access to electricity, and is expanding to adjoining countries.

There are a range of lights and chargers offered from a variety of manufacturers, each with a two-year replacement warranty and up to five years battery life.

The cheapest, at $10, is a study light that gives four hours of bright light after a day’s charge, while the more expensive models offer light for up to 100 hours, charging for up to two phones at a time, and radio charging. The most expensive, which cost around $140, are designed for small businesses.

Even oil companies are selling solar lights now!

SolarAid began life in 2006 when the British company SolarCentury, one of Europe’s leading solar companies, began donating 5% of its profits to the charity. SolarCentury’s founder, Jeremy Leggett, says that the charity benefited by £28,000 in 2006, but the company’s increased profits mean that the figure will be nearly £500,000 this year.

“We were the first in the field back then, but now there are many solar lights of all kinds on the market”, Leggett says. “Most of them very good, although there are some ghastly cheap products that do not last, which can harm solar’s reputation.”

He says the company donations had been matched with other corporate and government aid. Ironically, even Total, the oil company, is now selling solar lights at its petrol stations.

Leggett believes that the market is growing so fast that there is a good chance of SolarAid reaching its goal of getting rid of all kerosene lighting in Africa by 2020.

He is hoping to build on his idea of donating 5% of corporate profits to climate change and poverty alleviation charities, and is launching a ‘5% club’ of enlightened businesses prepared to do the same.

“Most companies would not miss 5% of their profits, and the gains are enormous”, he says. “In my company, the programme is a great favourite with staff and gives everyone a feel good factor. Compared with other similar companies, we retain staff longer because they feel their work is more worthwhile.”

Victory in prospect for Peru’s Kichwa People after 40 years of oil pollution





Hundreds of of Kichwa indigenous people living along the River Tigre in the remote Peruvian Amazon are demanding over 100 million Peruvian nuevo soles ($32 million / £21 million) from oil company Pluspetrol in the “environmental damages” they have sustained over 40 years of oil drilling.

The Kichwa men, women and children blockaded the River Tigre for most of January with two cables – stopping two boats contracted by Pluspetrol to carry equipment, materials and supplies upriver to oil dilling sites.

The blockade was only suspended last Friday after Fernando Melendez Celis, President of the vast Amazonian region of Loreto, paid a visit to the protesters, camped by the side of the river on land belonging to Kichwa community Nuevo Remanente.

“Loreto now has a president that will fight for your rights”, Melendez Celis told the Kichwas. “I’m here to tell you the regional government will fight for you. These territories belong to you.”

The blockade is the latest manifestation of a new militancy among the indigenous peoples of the Peruvian Amazon. Last December the Matsés people whose territory straddles Peru’s border with Amazonas, Brazil threatened at attack any oil workers entering their lands.

Oil pollution an ‘environmental emergency’

Pluspetrol’s concession, Lot 1-AB, is Peru’s number one oil producer. Operated in partnership with PetroChina, it yielded almost 25% of all Peruvian oil in 2013.

But operations there have led to severe contamination leading the government to declare an “environmental emergency” in the river Tigre basin in late 2013. Water samples from the Tigre and its tributaries revealed dangerous levels of lead, nickel, iron and aluminium – leaving local communities no water fit for human consumption.

The Kichwas are also demanding compensation for land use, environmental clean-up, and to be consulted by the government about the concession contract which expires this August, among other things.

Numerous Kichwas say that the Tigre and other water sources are contaminated, meaning that they, as well as the game and fish they depend on to survive, are slowly being poisoned.

“Our fathers and our in-laws are dying”, said Edinson Munoz Moscoso, from Remanente. “We, the survivors, are fighting for the benefit of our sons and daughters.”

“There have been 45 years of contamination”, said David Inuma Sabaleta. “The Kichwas, the agoutis, the tapirs, the water … all poisoned. Our fathers and grand-fathers have died because of this.”

“We use the water for everything: to drink, to wash, to cook”, said Orlando Chuje Aranda, another Remanente resident. “It’s contaminated, but we have to use it because there’s no other option.”

“After 45 years of oil operations, we want to be able to drink water that isn’t contaminated”, said Carlos Huaya Luna, from the Vista Alegre community. “Here, we’re fucked. Boys, girls, women … how many people have had to suffer for us to reach this point? That’s why we’re protesting.”

Pluspetrol and Peruvian government forced to negotiate

The blockade was suspended after Melendez Celis agreed to broker a meeting in the nearest city, Iquitos, between Kichwa leaders, Pluspetrol, and the central government’s Council of Ministers (PCM).

And on the same day that Melendez Celis set off for Remanente, Peru’s Energy Minister said the government will invest 100 million soles in the Tigre and other rivers where environmental emergencies have been declared.

Calls were made by satellite phone to Pluspetrol and the PCM in Lima, and Melendez Celis committed to attempt to ensure that Peru’s Prime Minister Ana Jara would participate in the meeting too.

A PCM representative present in Remanente at the same time made various proposals to the Kichwas, including 3.5 million nuevo soles for land-titling, but they insisted on dealing with higher-level personnel.

“We don’t want a speech”, Fernando Chuje Ruiz, the newly-elected president of Kichwa federation FECONAT told the PCM representative, Jose Antonio Caro. “What we want is Ana Jara to be here.”

Melendez Celis, whose term as President of Loreto started last month, told The Ecologist the contamination made him feel like a “Kichwa brother”, that he is “assuming their fight” and will “protect them and their rights.”

“The state has been indolent”, he continued. “It has punished its indigenous peoples and forgotten them. No longer. My dream for Loreto is that policies are much more just.”

Melendez Celis also committed to ensuring more oil revenues are invested in the Tigre region, and to paying for studies estimating the financial value of the environmental damage.

If our demands are not met, the blockade continues!

FECONAT issued a statement last week laying out various demands, and stressing that compensation and consultation are rights recognised by law. “For the first time in our history the Kichwa people has risen up in defence of our rights“, the statement reads. “We’re with our families fighting to be heard.”

According to the statement Pluspetrol and Occidental, which operated Lot 1-AB from the early 1970s until 2000, have destroyed Kichwa lands and committed “genocide” while “the state has never defended us …

“We want to make it clear we are not against development or oil operations. But nor are we going to allow ourselves to be made extinct in the name of development.”

The meeting between the Kichwas, Pluspetrol and the PCM was initially scheduled for yesterday, but according to Melendez’s media officer, Leonardo Caballero, it will take place this week, “possibly Wednesday.”

The Kichwa protests are “unprecedented”, said Jorge Tacuri, a lawyer acting for the Kichwas, who accompanied Melendez Celis to Remanente. “Never have the Kichwas protested as they’re doing now. They’ve put the Tigre on the national and international agenda. The central government has agreed to sit down with them.”

Tacuri points out that the suspension of the protest may only be temporary, depending on the outcome of today’s meeting, adding that the Kichwas’ camp at ‘Base Tigre’, an old oil operations base, is built to last: “They brought all their stuff to live there. They weren’t joking when they said they would protest for a year.”

How does climate variables and diversity loss “filter” natural communities?

As the oceans gradually become warmer and more acidified, an increasing number of studies test the effects of climate change on marine organisms. As most climate change experiments have studied effects of single climate variables on single species, more and more researchers ask themselves how this lack of realism affects our ability to accurately assess and predict effects of climate change (Wernberg et al. 2012). Interestingly, theory and a growing body of studies suggests that different climate variables can strongly interact (Kroeker et al. 2013), that climate effects can change with presence/absence of strong consumers (Alsterberg et al. 2013), and that effects on communities are more informative than those on single species, as they allow experimenters to assess what traits that makes organisms sensitive or resistant (Berg et al. 2010). In our new paper “Community-level effects of rapid experimental warming and consumer loss outweigh effects of rapid ocean acidification we found that warming and simulated consumer loss in seagrass mesocosms both increased macrofauna diversity, largely by favoring epifaunal organisms with fast population growth and poor defenses against predators.

Eklöf1

These results corroborate theory, and exemplify how trait- and life-history based approaches can be used to in more detail understand – and potentially predict – effects of climate change. Meanwhile, simulated ocean acidification (pH 7.75 vs. 8.10) had no detectable short-term effects on any of the investigated variables, including organisms with calcium-carbonate shell. While this lack of effect may be partly explained by the short duration of our experiment and/or the relatively crude endpoints, seagrass-associated macrofauna routinely experience diurnal pH variability that exceed predicted changes in mean pH over the coming century (Saderne et al. 2013). Consequently, by living in a variable pH these organisms could be relatively resilient to ocean acidification (see e.g. Frieder et al. 2014). In summary, it seems that at least in the short term, rapid warming and changes in consumer populations are likely to have considerably stronger effects than ocean acidification on macrofauna communities in shallow vegetated ecosystems.

The Greens need coherent policies on population and immigration





Those famous electoral TV debates are getting closer – and it’s intriguing to imagine the dialogue between UKIP leader Nigel Farage and the Green leader Natalie Bennett.

One big area of disagreement is of course immigration, and the Greens’ immigration policy is, in their own words “liberal” – which in practice means absolutely no constraint or restriction on who enters the or stays in the UK.

Specifically, the Green Party “will progressively reduce UK immigration controls” and give non-Europeans the same free-movement rights as Europeans. That is, everyone is free to move in.

In my opinion, Bennett will struggle to defend this policy in debate with the populist Mr Farage, given the large scale immigration it would be certain to provoke if implemented any time soon. Even committed Greens will find it unrealistic – except as a very long term aspiration.

More cynically – has the Green Party given any thought to what the electoral consequences will be when their open door policy becomes widely known? As Mr Farage will surely make sure it does?

People look to the Greens for the promise of a long-term sustainable future for their descendants and the UK, as well as the Earth itself. So a policy that appears to actively negate that aspiration – by encouraging overpopulation and cultural instability – must undermine the party’s credibility in many voters’ eyes.

The population question

As a green (Oxford Ecology Movement) candidate in the 1979 general election I can quote our policy at the time: “The national aim is a replacement birth-rate in the short term, followed by a gradual reduction over the next 1 or 2 centuries to 20-30 million in Britain, achieved through education and popular consent.”

The Green population policy today is less specific, worthy but lacking in substance –  focussed more on global than UK issues, which enables the more political and controversial issue of the UK population (and the link to immigration) to be fudged.

The main thrust appears to be that we’ll need to look at population at some undefined future date (PP101, 103), but in the meantime we can have as many children as we like (PP106) and let everyone in who wants to come (PP111), provided we keep half an eye on “economic and environmental pressures”.

It is all very vague and woolly, and while it implies the need for an eventual limit, there is no thinking about what a sustainable population for the UK might be, thus also no means to achieve it, even if lip-service is paid to population being a proper subject of public debate (PP107).

There is a medium-term aim (PP120) “to promote debate on sustainable population levels for the UK ­ … to increase awareness of the issues not to set specific population targets.” But to discuss a sustainable population for the UK without having any idea of what you are aiming at seems, for a Green policy, worse than pointless.

Surely the essence of the green approach to life and humanity is long-term sustainability? So difficult issues like actual numbers and how to achieve them need to be openly and clearly discussed.

The emphasis is however on world population limits. Indeed some local Greens have suggested to me that as long as the total world population is stabilised, it doesn’t matter how people are distributed. So it’s OK for lots of people to flood into nice rich UK as this will result in fewer poor people somewhere else.

So apparently we should ignore our own interests in order to altruistically solve those of others currently less fortunate. It’s a noble wish, but surely each country needs to have policies that at least safeguard their own viability?

The debate must be allowed to take place

Fortunately the Green population debate is far from over. In recent posts on The Ecologist, Biff Vernon has argued for a population policy by stealth focussed on women’s status and health in poor countries, while Simon Ross from Population Matters argued that evading the core issue is dishonest and that in any case we have issues here in the UK.

Rupert Read, the Green prosective candidate for Cambridge, has also thrown his hat in the ring, in an Ecologist article that outright opposes mass immigration: We Greens need to be absolutely and resolutely pro-immigrant – while turning against large-scale immigration.

The Ecologist‘s founding editor Edward Goldsmith would probably have sided with Read and Ross. As he wrote in 1989 in ‘The population explosion‘, “A growing population is not intolerable per se but because of the increasing impact it must have on the natural environment. This impact is greatly magnified by the increase in material consumption made possible by economic development.”

But not only does the Green Party today have no coherent population policy, there is a campaign within the party to denigrate and censor the one UK organisation that does, Population Matters.

Already banned from advertising in Green World, the activist promoting this exclusion, Adam Ramsay, has also recently persuaded my local party in Oxfordshire to prevent Population Matters from having a stall at our annual Green Fair, a popular fund-raising event held in December, with stalls from all manner of ethical-ish small traders, wildlife/animal welfare groups, and various right-on campaigning groups.

Ramsay’s views are online on two blogposts on Green European Journal and Bright Green Scotland with vigorous counter-argument and comments under each, taken up also by Derek Wall on Another Green World.

Ramsay’s arguments at the Oxford meeting were emotive – he invoked supposed population bogeyman Thomas Malthus (see Wikipedia for a balanced view), the 19th century Irish potato famine, a Swiss population group using the term ‘lebensraum‘ (‘living space, biosphere’, but used by Nazis and therefore bad).

And all that before he finally got round to two of Population Matters’ policies that are said to clash with what is acceptable to the Green Party: means-tested benefit on 3+ children and “no net immigration”.

Natural partners, not enemies

Apart from the two policies just mentioned, Population Matters’ aims closely match those of the Green Party – resources, pollution, energy usage etc – so why not try to work together?

In their 2015 manifesto Population Matters specifically state that they don’t want to increase poverty, hence their 3-child policy is flexible, and “no net immigration” isn’t a ban on immigrants as opponents like to make out, but an attempt to limit immigration to the numbers leaving, currently over 300,000 annually!

Thus there is plenty of room to ‘agree to differ’ on these themes, and in any case, as already discussed, I would suggest the Green Party needs to take a long hard look at their own shortcomings in this area. Most particularly there is no defensible case for the censorship and bans that these campaigners are so keen to enforce.

The Oxfordshire party has 700 members, but the decision was taken at a business meeting attended by about 25 people, with 12 voting for the ban, 5 against and several abstentions. Should important decisions affecting potential allies be taken so cavalierly ?

Both immigration and population are widely misunderstood. Immigration, or rather calls for it to be curtailed, is all too often seen in a racial or racist context. Clearly that motivates some, but we should not all be tarred with that brush – from a sustainability perspective, it makes no difference whatever what colour, race or religion extra people are.

They are, simply, people – and with our 413 people per square kilometre, England has recently overtaken The Netherlands as the most densely populated country in Europe – excluding city states. Wales, Northern Ireland and especially Scotland are less heavily settled.

For a long-term future any country needs to be fundamentally self-sufficient in food – we shouldn’t have to rely on imports, as in the long run there may not be surpluses available to buy – though exchanges are of course acceptable. Oats for bananas, anyone?

At present UK population levels this would only be possible if a lot more grain went into people’s mouths rather than meat animals, or a lot more land was (re)converted to high-intensity arable, itself unsustainable long-term. Also we have a responsibility to the planet’s other life, so we need wild space for both that life and for our own wellbeing.

Hence ever-increasing overcrowding is not desirable. I have heard local Greens pointing out that as there are some places more densely settled than England, then we can take more people. But that begs the question – why should we? do we want to? what good will it do us?

We can’t just wait for the global ‘demographic transition’

I’m not for a moment suggesting that population should elbow out the other major issues facing us all – ecosystem destruction, per capita consumption and related CO2 emissions and other pollution being obviously among the most serious, with their additive impacts on global warming and climate change.

However tackling the consumption / pollution aspects without including the population factor smacks of wilful blindness to the facts. The ‘demographic transition’, whereby increasing affluence reduces birth rates, has no doubt delayed the crunch point, but more importantly has lulled people into a false sense that population will somehow solve itself if we can sort out poverty across the planet.

Goldsmith was in fact trenchant on that point: “To seek to reduce population by systematically encouraging economic development is thus self-defeating since it can only increase natural consumption and thus environmental destructiveness.”

And it shouldn’t be forgotten that most of the last century’s massive world population growth arose from medical advances reducing infant and other death rates, not from increasing birth rates. It therefore makes sense to actively encourage a balancing reduction in birth rate, something that is a cultural block in many places.

Some cultures have responded quite rapidly with a demographic transition, but others, Egypt for example, have failed to do so, producing populations dramatically unbalanced with disproportionate numbers of young people and numerous negative knock-on effects from that including unemployment and wider disaffection.

In some developed countries like Japan and Italy where birth-rates have dropped, there is panic in conventional economics about the opposite problem: a preponderance of the elderly, seen as dependent on the workforce.

Hence there is a tendency to promote pro-natalist policies, or increased immigration, to offset the numbers of pensioners. In practice this is what has been happening in the UK, as millions of immigrants have flowed in over recent decades, many from Asia or Africa bringing in addition a tendency to higher birth-rates.

Having your cake and eating it

The Green Party rightly opposes “economic order that supposes the need for an ever-growing younger population to support the retired” (PP114) yet supports unrestricted immigration and “that the number of children people have should be a matter of free choice” (PP106).

But this is having your cake and eating it. There is ample evidence that increasing population exacerbates the already severe human impacts on the environment and the planet’s carrying capacity. Indeed as Jonathan Porritt points out,

“we are already using 50% more resources than the Earth can sustainably provide, and unless we change course very fast indeed, even two planet Earths will not be enough to meet our burgeoning economic demands (on a business-as-usual basis) by 2030.”

Addressing consumption alone is only taking half-measures, and won’t stop the crunch. There are limits to growth, both economically and in population – why are we still ignoring these when the basic issues were thrashed out ad nauseam in the 1970s, not least by Goldsmith.

We don’t know exactly where these limits are, and finding out should be a priority, but with ‘known unknowns’ it is advisable to follow the precautionary principle, particularly when its the one and only home planet that is at issue!

And the Green Party should not be afraid to say so!

Polish farmers block motorways for land rights, no GMOs





Poland’s biggest ever farmers’ protest is now entering its second week after closing down key motorways and main ‘A’ roads.

Rallies and blockades have so far taken place in over 50 locations across the country involving thousands of small and family farmers.

Over 150 tractors have been blockading the A2 motorway into Warsaw since the 3rd February and hundreds more have closed roads and are picketing governmental offices in other regions.

The farmers are vowing to continue the struggle until the government agrees to enter talks with the union and address what the growing crisis in Polish agriculture, and roll back measures that unfairly discriminate against smaller family-run farms.

“We are ready for dialogue”, said Edward Kosmal, chairman of the farmers protest committee for West-Pomeranian Region. “We look forward to meeting with you, Prime Minister, and beginning a comprehensive government commitment to solving the problems of Polish agriculture.

“If you do not enter into a dialogue with the Union, we will be forced to step up our protests.”

Key demands: land rights, no GMOs, legalize farm food sales

The four key demands of the farmers are:

  • Land rights – implement regulation to prevent land-grabs by Western companies and to protect family farmers rights to land – from 2016 foreign buyers will be legally able to buy Polish land.

  • Legalize direct sales of farm produce – the government must take action to improve farmers’ position in the market, including the adoption of a law to facilitate direct sales of processed and unprocessed farm products (NB. Poland has the most exclusionary policies in Europe around on-farm processing of food products and direct sales, which make it impossible for family farmers to compete with bigger food companies).

  • Extend inheritance laws to include land under lease as a fully legal form of land use.

  • Ban the cultivation and sale of Genetically Modified Organisms in Poland

“We demand a legal ban on GM crops in Poland”, said one protesting farmer and Solidarity member. “The value of Polish agriculture, unique in Europe, is the unpolluted environment and high quality food production. That’s decisive concerning our competitiveness in global markets.”

Another added: “We demand the introduction of legislation that will protect Polish land from exploitation by foreign capital! Agricultural land cannot be sold to commercial companies. It’s part of Polish territory. Once sold it will be lost.”

A dramatic escalation

These actions represent a dramatic escalation of protests that have been simmering across the country over the last year, but especially in the northern provinces.

An immediate cause of discontent has been oppressive ‘food hygiene’ and other regulations that effectively present small scale farmers from selling their produce on-farm and in local markets, where their mostly organic (if uncertified) produce is widely respected as of higher quality than food gown on modern industrial farms.

Poland is one of the last European countries that still has a large body of small scale ‘peasant’ farmers who still use traditional agricultural methods free of chemicals and with very low levels of mechanization, with horses still widely used for traction.

Farms are typically mixed, with small number of pigs, chickens, cattle and horses and arable fields all contained on around five hectares.

However industrial farmers are keen to expand their operations and many family farmers see the increasingly stringent regulations as an attempt to force them off their land.

Industrial farmers are welcomed by Poland’s right-wing government, for example Smithfield, the world’s biggest pig producers, which bought Poland’s Animex SA in 1999 and now runs a string of 16 or more huge hog farms where animal welfare conditions have been described as horrendous.

Julian Rose, President of the International Coalition to Protect the Polish Countryside (ICPPC), explained: “We are witnessing a sharp escalation in activity by Polish farmers squeezed by EU, government and corporate interests.

“These protests are touching the raw nerve of what’s wrong with the inhuman, neo-liberal and profit obsessed practices of today. Practices which ignore the real needs of farmers and consumers alike.”

Fracking company defies Wales’s shale gas moratorium





IGas has responded to a motion passed at the Welsh Assembly this week stating the Welsh Government’s opposition to shale gas extraction, declaring “they have no power to stop fracking!”

The motion calling for a fracking moratorium was tabled by Plaid Cymru, and passed with the support of Welsh Labour Assembly Members by a large margin: 37 for and 16 against. 

Despite the cross party backing, the Welsh Government has yet to take action. Labour’s economy minister Edwina Hart, who backed the Plaid motion calling for a moratorium, has turned down calls for planning advice on fracking to be updated.

But insiders have indicated that the First Minster, Carwyn Jones, is currently seeking legal advice on what powers the Welsh Government has to effectively place a moratorium on fracking.

The UK Government currently has control over shale gas licensing but the Welsh Government has responsibility, in theory, for any related planning applications. But any appeals against refusals are judged by the London-based Planning Inspectorate for England and Wales.

And as IGas helpfully points out, these devolved planning powers render the Welsh Government helpless in protecting Welsh communities against any unwanted developments.

IGas: ‘we’re going ahead anyway’

The original IGas application to carry out test drilling at a site in Borras, near Wrexham was rejected by the democratically elected councillors on the local authority. The company then appealed against the decision, which went to the Westminster-controlled Planning Inspectorate, which overturned the earlier refusal.

An IGas spokesman told the Daily Post: “Nothing has changed in our plans to test drill for underground gas in Wrexham, which we will be continuing with.

“And if we were to put in a planning application in the future, which is rejected by Wrexham council, the appeal would go to the Welsh Secretary, which comes under Westminster, not the Welsh Government.

“The decision by the Welsh Government was not a moratorium. They can refuse applications on planning grounds, but they have no power to stop fracking.”

As Sion Chavez, editor of Daily Wales, points out, “It’s a situation which highlights the absurd consequences of having one country administered by a neighbouring country.”

“Scotland and Northern Ireland each have their own completely separate Planning Inspectorates which allow their own governments to oversee any appeals. But in the case of Wales, it’s the Planning Inspectorate for England and Wales.”

The SNP controlled Scottish Government has recently used its control over planning to announce an immediate moratorium on all fracking applications.

Welsh Government must be firm

Gareth Clubb, Director of Friends of the Earth Cymru, commented: “As soon as this legal advice is available, it needs to be published so that all the people of Wales can know where we stand on this problem.

“If a moratorium is within the Welsh Government’s powers then it just needs to get on and make it happen. If a ban isn’t possible, two things need to happen straight away. The first is that any powers restricting Wales’ ability to protect its communities should be devolved immediately.

“The second is that until those powers are devolved the Welsh Government must issue a Planning Policy Statement with a presumption against the development of unconventional oil and gas onshore in Wales.

“Anything other than these steps will suggest that the Welsh Government was being duplicitous through voting in favour of doing everything in its power to prevent fracking in Wales, but failing to take the action needed to deliver on its promise.”

Among other clauses, the successful motion calling for a fracking moratorium “Believes that energy should be fully devolved to the National Assembly for Wales and that the Welsh Government should have the power to block fracking.”

It further “Calls on the Welsh Government to do everything within its power to prevent fracking from taking place in Wales until it is proven to be safe in both an environmental and public health context.”

Illegal Swedish fishery is ‘certified sustainable’





Last week a lobster fishery in the Kattegat, the area of sea between northern Denmark and Sweden, is the proud recipient of a ‘sustainable fishing’ certificate through the Marine Stewardship Council (MSC).

But only four months ago Citizen Inspectors of The Black Fish (TBF) – an Amsterdam-based environmental group dedicated to preventing illegal overfishing in European seas – observed fishermen illegally targetting protected cod stocks in the exact same fishery – and has the photographic and video evidence to prove it.

But the MSC has decided to disregard the evidence of illegal activity, prompting Wietse van der Werf, TBF’s International Director, to comment:

“Sustainability labels mean very little if certifiers are not digging deeper to find out what is really happening in fisheries. Surprise inspections and undercover investigators would be a good start.”

The evidence collected by TBF’s Citizen Inspectors will not be made public, pending its use in possible legal action, adds van der Werf: “We will continue to build on our findings as with more evidence we stand a stronger case.”

Good lobster, bad cod

The ‘sustainable’ fishery targets Norwegian lobster (also known as nephrops) with trawlers. But the Kattegat also contains important spawning areas for cod, which has been heavily overfished in the area over recent decades.

So the area contains two fisheries: a sustainable lobster fishery, and a very unsustainable cod fishery. Complicating the picture, Kattegat trawlers often catch the lobster and cod together in the same net, continuing the negative impacts on the troubled fish.

To protect the cod, while allowing the lobster fishery to continue, the Swedish authorities imposed new rules requiring fishers to fit specially designed grids in their trawl nets that create openings that adult cod caught up in the net can escape through, while retaining the lobsters.

But as one as of TBF’s Citizens Inspectors explains: “During the inspections we found multiple steel grids which weren’t properly attached to the trawl nets, allowing for an opening to be created underneath the grid, so cod could be caught.

“One net even used chains as weights to open up the net further, making the fitted grid totally useless. On another occasion we observed fishers re-attaching their nets upon return to the port, presumably for the net to meet the requirements during a possible inspection by fisheries officials.”

But the lobster will continue to carry the MSC label

In spite of the evidence of illegal ‘black’ cod fishing in the Kategat, products from the nephrops fishery will now bear the Marine Stewardship Council (MSC) label for ‘sustainable fisheries’.

TBF notified the MSC about its findings but learned that the formal assessment period for the fisheries had already passed, so it was too late for their evidence to be taken into account.

Annual surveillance audits are carried out by the certification body but according to van der Werf, “we fear that these will yield little result in uncovering illegal activities, in part because they are publicly announced before they take place.”

By contrast, TBF’s Citizen Inspector Network carried out over 100 inspections in Swedish fishing ports last August, identifying numerous trawl nets illegally modified to prevent the cod’s escape.

Phenotypic effects of climate change

Understanding how changes in the climate affect biological communities is essential in predicting the future size and composition of populations. However, accurate predictions pose a difficult challenge for researchers. For the majority of animal species it is not feasible or ethical to conduct experiments into how these populations will respond to a changing climate. To enable us to gain an insight into potential futures of a population under climatic change, we use a computational model. Specifically, we use an integral projection model to investigate how changes in the North Atlantic Oscillation will influence the body weight and population size of a population of Soay sheep. The North Atlantic Oscillation is a large scale weather pattern of temperature differences across the Atlantic Ocean, which alters the local weather patterns in the North Atlantic region. We used published predictions of the future values of the North Atlantic Oscillation for the 21st Century. By doing this we are able to project the response of the study population to climate change based on our current best projections of the future climate.

Soay

Our model results, presented in the Early View paper “Analysis of phenotypic change in relation to climatic drivers in a population of Soay sheep”,  suggest that a continued positive trend in the North Atlantic Oscillation (positive pressure difference between Iceland and the Azores), as predicted by the majority of models, will be accompanied by a decrease in the population size of the Soay sheep and an increase in mean body weight. These changes are likely caused by a loss of smaller individuals from the population due to higher mortality in the adverse winters (mild but wet and windy) associated with the positive North Atlantic Oscillation.

Using an integral projection model as we have in this study gives us a glimpse into the potential future of populations where experimentation is difficult, and can improve our understanding of how populations will respond to changing climatic conditions. Using published climate predictions within our model also allows such studies to be placed in the realm of current climate research and (importantly) our projections can be updated as new climate predictions are released.
