Are We Prepared to Make Changes?

Abridged article based on article by Gaby Hinsliff, columnist,  The Guardian, April 19 2019.

At this critical time…    Stores know (that many of) their young customers are eco-conscious, impressively fluent in the evils of plastic and diesel, where as past generations were oblivious. But they’re also human, still occasionally craving the disposable fashion they’ve always had. They want what most people secretly want, which is to enjoy the pleasures of a pre-climate-conscious age – foreign travel, strawberries out of season – but in ways sustainable enough to let us feel good about it…

To watch passing shoppers and tourists stop and film (climate protesters) on their camera phones is, however, to wonder how prepared we really are for the life of minimal consumption inherent in treating climate change as an emergency. The protesters have public sympathy for their broad aim in the bag. But that’s a very long way from securing public consent to the specifics…

In practice, that (would) indicate the kind of collective effort rarely seen outside wartime. It means goodbye to petrol cars, gas boilers and cookers – fine for those who can afford to replace whatever they’ve got now, impossible for the poor without significant subsidy and, hello to restrictions on flying. It implies eating significantly less meat and dairy, and no longer treating economic growth as the first priority, with all the possible consequences that entails for pay, tax revenues and public services. We might hope to create jobs in green industries but shed them in carbon-based ones but with no guarantee of the new, clean technologies basing themselves in those towns hardest hit by the loss of the old, polluting industries.

All of that might be necessary to stop global warming in the long run, but the difference is that doing it in six years, not 30, means it would have to happen at breakneck speed, with painfully little time for communities to adjust. Those who are prepared to accept sacrifices for themselves need to be honest about what they’re wishing on others, which is why alarm bells ring when Extinction Rebellion’s Gail Bradbrook says that “this is not the time to be realistic”. We’ve seen in the three years since the Brexit referendum what can happen when campaigners win an argument by refusing to be realistic about what their dream means for other people.

UK Will Miss Almost All 2020 Wildlife Targets

Damian Carrington & Patrick Wintour, The Guardian, March 23 2019. Abridged.

The UK will miss almost all the 2020 nature targets it signed up to a decade ago, according to a report by the government’s official advisers. The nation is failing to protect threatened species; end the degradation of land; reduce agricultural pollution; and increase funding for green schemes, the assessment concludes. 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 targets were set in 2010 by the global Convention on Biological Diversity (CBD) and the report from the joint nature conservation committee (JNCC) found insufficient progress was being made on 14 of the 19 targets.

The news came on the day Britain formally launched its bid to host the UN climate change conference in 2020, seeking to prove its green credentials are not tarnished and to show the disarray that has been caused by Brexit does not mean the UK has forfeited its right to be a major international player. Speaking at a launch event for the bid in Downing Street, the foreign secretary, Jeremy Hunt, said: “Most importantly of all, we are ambitious. If we are going to ensure that future generations do not pay a price for our prosperity today, we must collectively change our economies and societies. We believe this can be done and protecting the environment can go hand-in- hand with economic growth.”

Critics of the government said the report showed wildlife and natural habitats were in deep crisis. The UK is “among the most nature-depleted countries in the world”, according to a separate 2016 report, with continuing declines in species such as skylarks, hedgehogs, many insects including butterflies and corn marigolds.

“The JNCC report says nature in the UK is pretty bad, declining and not recovering, and that is in the context of an awful lot of rhetoric [from ministers] about being a world leader on the environment,” said Kate Jennings, the head of site conservation policy at the Royal Society for the Protection of Birds (RSPB).

The environment minister Thérèse Coffey said: “Nature matters. Our species and ecosystems are valued in their own right, but they also contribute to our wellbeing and economic prosperity. We acknowledge that in many areas there are ongoing declines in nature, but there are real points of progress on which we can build. Our 25 Year Environment Plan is a step-change in ambition.”

A key CBD target is to improve the conservation status of threatened species but the report says “there have been widespread and significant ongoing declines across many species”, such as farmland birds and pollinating insects. Another of the 2020 targets is to cut the rate of loss and degradation of natural habitats to “close to zero”. While the report says some places have improved, there have been “ongoing losses of natural and semi-natural habitat, for example through neglect or development”.

The target to cut fertiliser and other pollution to levels that do not harm biodiversity is being missed, the report says, with little reduction in sensitive habitats since 2010 and with 65% of inland and coastal waters remaining below target levels.    Only about half of fish stocks are sustainably caught, the report says, meaning the target to end overfishing will be missed.

Salt Marshes – Our Unsung Landscapes

Salt marshes are the unsung heroes saving our coastlines

Paul Simons, The Guardian, Tue 19 Feb 2019.

Salt marsh in Norfolk.

Salt marshes are not glamorous – muddy flats on coasts and estuaries, washed with seawater on the tides, where only specially adapted plants can survive in such a tough salty environment.  Although frequently ignored, salt marshes are unsung heroes. They help protect coastlines from storms, storm surges and erosion by creating a buffer between dry land and the sea, building up the height of the coast by trapping silt during floods and adding new soil from their decaying vegetation.

Less well known is that salt marshes lock away vast amounts of carbon by taking carbon dioxide out of the atmosphere through their plant leaves and storing it in the roots. And, when the plants die, the carbon becomes part of the soil. Salt marshes also provide a refuge for birds, fish and invertebrates; they provide clean water by filtering runoff, and they are low maintenance because they naturally self-repair.

But, in many places, salt marshes have been destroyed by drainage for land reclamation, coastal developments, sea walls, pollution and erosion. Globally, about 50% of salt marshes have been degraded and the rest remain under threat.

Schemes to restore salt marshes have proved successful, though, such as the Wallasea Island project in Essex, the largest scheme of its kind in Europe. Land that had been reclaimed for agriculture long ago has been turned back into wetland.

Agroecology – the Future of Food Production?

https://www.theguardian.com/environment/2019/feb/20/european-farms-could-grow-green-and-still-be-able-to-feed-population

European farms could grow green and still be able to feed population.

Rebecca Smithers, The Guardian, Wed 20 Feb 2019.

Europe would still be able to feed its growing population even if it switched entirely to environmentally friendly approaches such as organic farming, according to a new report from a think-tank.

A week after research revealed a steep decline in global insect populations that has been linked to the use of pesticides, the study from European thinktank IDDRI claims such chemicals can be phased out and greenhouse gas emissions radically reduced in Europe through agroecological farming, while still producing enough nutritious food for an increasing population.

Agroecology takes into account natural ecosystems and uses local knowledge to plant crops that increase the sustainability of the farming system as a whole. The IDDRI study, entitled Ten Years for Agroecology, used modelling to examine the reduction in yields that would result from a transition to such an approach.

Reductions, the authors argue, could be mitigated by eliminating food-feed competition – reorienting diets towards plant-based proteins and pasture-fed livestock, and away from grain-fed white meat. More than half the EU’s cereals and oilseed crops are fed to animals. The study models a future in which European meat production has been cut by 40%, with the greatest reductions in grain-fed pork and poultry.

“Pesticide-hungry intensive production is not the only way to feed a growing population” said Rob Percival, the head of food policy at the Soil Association. “The Ten Years for Agroecology study shows that agroecological and organic farming can feed Europe a healthy diet, while responding to climate change, phasing out pesticides, and maintaining vital biodiversity.”

The study suggests that agroecology – using ecological principles first and chemicals last in agriculture – presents a credible way of feeding Europe by 2050. But it says action is needed now, with the next 10 years critical in engaging Europe in the transition. The agriculture bill now going through parliament in the UK makes no mention of agroecology, although an amendment drafted by a cross-party group of MPs proposed that farmers using the approach should receive some sort of payment.

Could flexitarianism save the planet?

“The idea of an entirely agroecological Europe is often considered unrealistic in terms of food security because agroecology sometimes means lower yields,” said Percival. “But this new research shows that by refocusing diets around plant-based proteins and pasture-fed livestock, a fully agroecological Europe is possible.”

The study is being published in parallel with the UK launch of the Eat-Lancet “planetary health diet”, which proposes a shift towards a more plant-based diet. The agroecology study addresses similar concerns, but places greater emphasis on farmland biodiversity.

Rewilding Making Strides Across Europe

Steam Powered!

Just spent a wet and breezy few minutes down at St.Leonards Warrior Square station to watch the steam loco ‘Union Of South Africa’ be hauled through on its excursion out from London Victoria to Hastings.  Ten minutes later it returned except that this time, it was pulling and was under load, as it built-up speed after departing from Hastings.  The sound as it came up through the long tunnel from Hastings was truly exhilarating!

The second image shows the big diesel now at the rear, this time being hauled – it only on tick-over.  There was a whole class of primary school children brought down to the station, plus those in the know and fortunate passers-by.

The Future of Home Heating?

Did you know that over 80% of UK homes are heated by gas, and that heating accounts for 1/3 of UK CO2 emissions?

The UK is actually doing more than it’s part to reduce carbon emissions – our goal of a 57% reduction in carbon emissions by 2030 dwarfs the EU goal of 40%.  Even more ambitiously, we want to reduce them by 80% by 2050.  The plan was, or is, to de-carbonise electricity production which has been happening with the push towards solar and wind energy.

The next step was to electrify heat.  The only problem is that the aggregate peak demand for heat is 300 gigawatts, which is more than five times the demand for electricity.  The problem is that at the moment coal and fossil fuels are proving more practical to store, and there aren’t that many alternatives.

However, there could be one…  Hydrogen could be the key to unlocking a sustainable energy economy.  Its main benefits are that it is next to carbon neutral, and it could be stored in fuel cells.  What’s more, the current gas pipeline is largely compatible with hydrogen, and the only real change consumers may have to make is to change their burners on their equipment.

There are already experiments happening over the UK, such as in Leeds where Northern Gas Networks and Wales & West Utilities are studying the feasibility of converting the existing natural gas networks to transport hydrogen.

They have found that: 1) the gas network has the correct capacity for the conversion, which would reduce emissions by 73%.  2) the network can be converted incrementally to minimise disruption.  Likewise Keele University have trialled blending hydrogen into the existing gas supply to prove that a hybrid could be rolled out to the public without disruption.

Finally, the Hydrogen for Heat programme aims to design and develop new appliances that can be run on hydrogen and explore the practicalities of using hydrogen in homes.  Eventually, they aim to implement a pilot project in a small village or town.
