Where Has The Water Gone?

Image
Two headlines caught my attention today. The first was from Tuesdays Glasgow Evening Times: Save water plea ... after wet summer It was about Scottish Water's recently launched campaign to encourage people to save water. The reason for this campaign is not a shortage of water but a drive to save energy in treatment and pumping of the water. While I do support any measures that we can take to reduce energy use and carbon emissions, I feel that this is Scottish Water trying to pass the responsibility on to the public rather than dealing with their own wasteful inefficiencies.  They lose more water through leakage than the total domestic consumption, as noted here , so whatever individuals do to save a little bit of water is nothing compared with the amount leaking from pipes.  The volume of water lost through leakage will not reduce even if the volume used by consumers is reduced significantly, in fact it may increase as the pressure in the system would increase (leakage is hig

Martyr or Mug

It’s early. 5:45 AM to be precise. I have a large paper cup of coffee in front of me with one of those dastardly plastic lids. The ones that jettison steaming hot coffee up your sleeve when you walk. Looking to my left, out of the window, I see the lights of the still sleeping city rumble by. Full of people snuggled up in bed, still in their own personal dreamland: dreaming of past glories and future ambitions, subconsciously sifting through the meaning of life. I should be there too. Now I look forward. I see a long and wearisome day ahead. Two days ago, my presence was requested, nay, demanded, at a meeting in London later this morning. Other commitments yesterday and tomorrow mean that I must travel there and back again in a day so I’m on the day’s first Virgin train service out of Glasgow. I hope to arrive 400 miles away in London in four and a half hours. I thought long and hard about how to travel. Whether to go for the speed of flying versus the slower but greener train, eve

The Changing Seasons

There was a nip in the air this weekend as the season begins to change and, if we needed it, a timely article in this Sunday's Independent serves as a reminder of some of the things we can do to save energy over the autumn and winter. The ten suggestions from the Independent are summarised below with some comments and a few other suggestions of my own: 1. Small changes - with emphasis on energy saving lightbulbs: Incandescent light bulbs are no longer available for domestic use so we should all be using low energy bulbs now or in the near future. 2. Efficient heating - ensure your radiators are working effectively and aren't blocked by furniture. Upgrading your boiler is also suggested but this can be a significant financial investment. The savings from upgrading your boiler depend on how inefficient the old one was and there may be other more cost effective energy saving investments. 3. Keep the heat in - draught proofing, loft insulation, cavity wall insulation and dou

Clyde Fastlink - A Revolution in Public Transport

Image
The problems with delivery of Edinburgh's new tram system has been well reported in the media, mostly because of the disruption caused by the works, its immense price tag and lengthy delays but Glasgow's bold new transport initiative has grabbed a lot less headlines, probably because of its more modest price tag and, more likely, due to its spectacular lack of impact on the city.

Here Comes the Rain - Part 2

Image
It is official. Britain has had the wettest summer since 1912 according to the Meteorological Office . This follows one of the wettest springs on record. Is this evidence of climate change or simply natural variation in the weather? To try answering this question, data from a weather station near Glasgow has been analysed . The first part of this article presented annual rainfall records and concluded that there has been only a slight increase in annual rainfall over the past decade compared with a baseline of 1961 to 1990 but that there had been a marked increase in variability. Also of interest is whether rainfall patterns have changed throughout the year, from month to month and between the seasons which is the subject of this post. In order to provide some context, June 2012 was the wettest recorded June in 54 years with 130mm of rainfall which is almost double(196%) the average rainfall for the month and July is the fourth wettest with 75% more than average. Apart from this year

Here Comes the Rain - Part 1

Image
Summer 2012 may be remembered for the Olympic Games. Or it may be remembered for the rain. From doom laden predictions of the worst drought for a generation in the southern half of Britain with disastrous consequences for farmers in the spring to torrential rain, floods and, yes, disastrous consequences for farmers in the summer. The burning question is whether this is just the natural variability of weather or whether underlying climate change has a hand in driving these weather systems. To investigate this question, I have studied some local weather records. My statistical skills are about High School level: mean and standard deviation of a normal distribution. Data for Glasgow Airport from 1959 to 2012 was obtained from the  Meteorological Office website but the 2012 data was discarded as it is only provisional and represents an incomplete year. The data included monthly rainfall, sunshine and maximum and minimum temperatures and the focus of this study was the rainfall data. Ann

Summer Holidays

Have you had your summer holiday yet? Did you stay local or did you fly away somewhere exotic? How do you fancy this three thousand mile trip: First stop off in France to soak up the culture then on to Mont Blanc and the Swiss alps for a few weeks rest and recuperation in the beautiful mountain scenery. It can be cool in the mountains, even in the summer so head south into Italy, perhaps Tuscany or further south again to Sicily. If that isn’t warm enough, take a short hop over the Mediterranean Sea to Libya then across the Sahara to Lake Chad. It’s not an itinerary that you’ll find in many travel brochures but it is quite popular in certain circles.  Mungo, a bird from near Loch Katrine made that very trip and met up with Chance who travelled by a different route from Loch Katrine, via Belgium and Austria, and Chris from the Norfolk Broads.  They are all Cuckoo’s that have been tagged by the British Trust for Ornithology (BTO) in order to track their annual migrations to Africa.  C

Water Saving in an Maritime Climate

I am fortunate to live in an area blessed with a plentiful supply of water.  Our maritime climate is driven by moist air coming in from the Atlantic Ocean, heated by the Gulf Stream.  The air cools as it rises over the mountains and loses its excess moisture as rain. Loch Katrine in the Trossachs has supplied the city of Glasgow with clean fresh drinking water for over a century and a half thanks to the work of the Victorian engineer John Frederick Bateman . When we have such an abundance of water there is little pressure to save water and you may be thought daft for even suggesting it but are there wider environmental benefits of reducing water consumption here?

Milk

Image
Sometimes nothing beats a cool refreshing glass of the milk. But the White Stuff is not as innocent as it looks. In fact, its cool clean exterior masks a multitude of sins. Milk has hit the headlines recently in a battle between farmers and the processors which are imposing cuts to the price paid to farmers for milk.  This is leading to farm gate prices which are less than the cost of producing the milk .  This is not a new fight.  For several years the large powerful dairies, such as Robert Wiseman (now owned by Müller), have put downward pressure on the farm gate price of milk.  This in turn has driven “efficiency” measures in the farming sector, i.e. industrialisation of the process.  About ten years ago I spoke with a farmer planning to build a huge shed so that his cattle could be kept indoors all year round.  This was, he said, due to pressure to cut costs. It was necessary of his farm was to remain sustainable .  The surrounding pasture that the cattle had grazed for generatio

Tell Shell

Image
Tell Shell that you don't want them drilling for oil in the Arctic. It is one of the least spoiled places on earth but Shell want to explore for oil. Climate change is more rapid in the Arctic than almost any where else on the planet, leading to greater areas of the Arctic Ocean being ice free than ever before in the history of oil exploration. This makes oil exploration easier, an opportunity that Shell are keen to exploit. But picture this: if a leak or spill occurs as the ocean begins to freeze over for the winter, there are no tools or methods available to contain and recover the oil. Floating booms won't work. Detergents won't work (and can cause damage themselves). The oil will be locked in the ice, travelling around the ocean until it melts next year, depositing a filthy slick

BMW Attacks Efficiency Targets

BMW accused of hypocrisy over opposition to European car targets | Environment | guardian.co.uk : BMW  is lobbying to water down European plans to improve the fuel efficiency of cars at the same time as trumpeting its green credentials as the  official car sponsor of the Olympic Games , according to internal documents seen by the Guardian. According to this Guardian article, BMW want to delay or reduce implementation of Europe wide fuel efficiency targets for 2015 and 2020.  BMW believe that premium  manufacturers (such as themselves) will be disadvantaged compared with manufacturers of normal cars. In other words people who can afford more expensive premium cars can afford the higher fuel prices and these wealthy people don't need to worry about climate change or limited supplies of oil.

Aphid Resistant GM Wheat

The Rothamsted Institute has frequently been in the news in recent weeks over their trials of a new genetically modified strain of wheat. This particular genetic modification splices genes from other plants, such as mint, hops or apples, which naturally produce an odour which simulates that released by aphids when distressed or under attack. This phenomenon has evolved in some plants as a natural defence as aphids that would otherwise attack the plant detect the odour and avoid the host plants.

Plastic Recycling

Image
Look at the recycling logo on a plastic bottle or container. It depicts a continuous loop, a virtuous circle, if you like, of plastic being made into bottles then being recycled into new bottles then the whole process repeating endlessly. Nothing falls out of the cycle and nothing new is introduced. It is a bit misleading. It doesn't take much imagination to realise that energy needs added to the process at the very least - energy for collecting the used plastic, treating it and manufacturing the new bottles. Less obvious is the fact that very few food grade bottles contain material from recycled bottles. Plant has been developed to do this but at this time its use not widespread.

"Recycling" Food Waste

There are moves afoot to begin uplifting food waste separately from other waste to allow energy to be extracted through the use of anaerobic digestion. On the face of it this sounds like a very good idea – not only does it extract energy but the residual waste can be used as a commercial grade compost, unlike the low grade compost extracted from Mechanical Biological Treatment (MBT) systems. This would see large reductions in material going to landfill. My concern is that large scale adoption of this technology will encourage more waste or, at best, stop any further reduction in the food we waste. Here is why.

Mechanical Biological Treatment: an alternative to kerbside recycling?

Continuing with the theme of Recycling Week, here is a brief introduction to Mechanical Biological Treatment of domestic waste. What is Mechanical Biological Treatment (MBT)? It is a method for sorting through domestic waste and separating it into materials that can be recycled such as glass, metals and plastics or organic materials that will decompose, such as food waste. What are the benefits of it?

City Living

Image
I took this photograph while out on a bike ride with the kids at the end of March this year.  I had been thinking about urban biodiversity after reading an article on Nature Deficit Disorder and this view captured my train of thought.  We are in Robroyston Park, one of Glasgow's parks which is designated as a Local Nature Reserve.  A diverse range of habitats are present. The pond at centre frame attracts the swans pictured and other birds, insects, fish and amphibians.  To the right of the frame is deciduous woodland providing cover for small mammals and birds, including a heron which nests in the trees and to the left we have rough grassland which is attractive to many insects and various ground nesting birds. Juxtaposed in the background are several blocks of high rise flats - a potent symbol our densely populated urban environment.

More Recycling, Please

Recycling week runs from today, the 18th of June until the 26th with the aim of promoting recycling at home and away. There are many events around the country promoted by the Recycle Now website run by WRAP (Waste & Resource Action Programme). The website also contains a lot of information on recycling. Recycling helps to conserve limited resources and using recycled materials often use less energy than virgin materials. In addition, recycling reduces the amount of waste that goes in to landfill, hence extending the life of existing sites and reducing the need for opening new sites at great environmental and social cost.  Recycling week is focusing on kerbside recycling (home) and recycling centres where you can take recyclable waste that is not collected kerbside(away).  Another aspect of "away" that does not appear to be addressed is the dearth of recycling options in public places.  In some countries, they standard pavement bin will have compartments for glass, metal

Electric Cars

Image
Glasgow is a compact city.  Nowhere in the city is much further than 10 miles from any where else.  It is perfect for electric vehicles(EVs) which typically have a short range. Pictured above are two of the forty electric vehicles being trialled by Glasgow City Council.  The trial which began over a year ago is scheduled to run for three years.  The vehicle fleet operated by the City Council comprises over 1200 vehicles of which over 350 are cars or car derived vans with the remainder including everything from small vans to bin lorries, minibuses and even articulated lorries. This is surely a welcome measure to reduce the city's carbon footprint and improve air quality. Or is it?

Can Organic Agriculture Feed the World?

I'd like to think that it can, but I have often wondered wether organic agriculture could feed everyone or whether we need more intensive agriculture. There are many environmental benefits to organic methods including reduced use of herbicides and pesticides such as neonicotinoids which are implicated in the decline of bee numbers. Another benefit is the greater diversity of vegetable varieties also associated with organic farming. This is for two reasons: to use varieties with greater natural resistance to pests and to use more flavoursome varieties to differentiate from non-organic produce.  A recent study of studies of yield from organic methods compared with so-called conventional methods has recently been published in Nature and reported here by the BBC. From the BBC report: The headline conclusion is pretty unequivocal; across the board, organic farming produces lower yields than conventional methods, by about 25%. For fruit, the difference is marginal, just a few percen

Plastic bags: it's not all about carbon

Image
I recently read an article which discussed how we could tackle the problem of the 800,000 tonnes of plastic bags thrown away each year in Europe, an average of 191 for every citizen of the European Union.  It highlighted the much smaller carbon footprint of disposable single use plastic carrier bags compared with alternatives.  Part of the article described re-using plastic bags as bin liners rather than using purpose made bin liners and it had a nifty graphic .  To a point, this makes sense but considering that many people use plastic bags for almost all of their domestic purchases, then to use every carrier bag once as a bin liner would require all that was bought to be disposed of in the bin.  I know that there is a lot of waste packaging in groceries but it does generally compact down to a smaller volume than the original (unless you live entirely on tinned produce) therefore assuming that all plastic bags are re-used in this way is stretching things a bit.  To then hypothesis

Even Worse Than NIMBYs...

I grew up in a small(ish) town before moving to the big city to study then settle down. I still go back to the small town from time to time and I notice the changes, some I like but others I don't. I like the riverside park that has been extended and I dislike the creep of houses and shops in to the countryside on the periphery of town. But I do not live there. I have chosen not too, therefore I must accept the changes made by those who do. In the big city we have many amenities; why should the small town not have some too if the townsfolk want them? Unfortunately there are some that don't see the world that way. They move to the bright lights but they want the old place to remain as it was when they left, as they remember it. They will go to great lengths to keep it that way despite the desires of those living there to improve the place. Worse still are those who have never lived there but have some ancestral ties that they believe gives them the right to decide what is an

Another Landslide

Another  landslide closes the A83 Rest and Be Thankful with the road expected to remain closed until at least Friday.  This time debris has not landed on the road but the remote monitoring system triggered an emergency closure. This landslip occurred after nearby Tyndrum recorded 54mm (2") of rain in 24 hours. Also announced today is a project to remove a bottleneck on the A82, which is the main route from Glasgow to the west highlands and the diversionary route when the A83 is closed.

How Green are Green Fingers?

Gardening turns out to be very eco un-friendly ... The Independent According to an article in this morning's Independent, gardening is not very environmentally friendly but I think that it depends on your approach.  This is my approach to minimising the negative effects of gardening: Compost I keep a compost heap for garden waste and vegetable trimmings which reduces the amount of waste being carted to a landfill site and produces a compost suitable for use as a soil improver.  Personally, I find it too coarse for use as a potting compost so I use a commercial peat-free compost for potting and other general purpose uses. I have successfully grown  potatoes in bags with a mixture of the peat-free compost and earth.  

Wind Energy Costs

Image
Following the recent attack on wind farms by MPS, I wanted to look at the cost of wind energy in fairly broad terms.  The latest attack on wind farm development is by a list of over 100 hundred Members of Parliament from across the political spectrum (I counted 2 Labour, 2 Lib-dems, one DUP, with the remainder being conservative) who wrote an open letter to the Prime Minister calling for a ban on any subsidies and tightening planning controls to make it easier for people to block developments. This coming from a government that wants to reform planning to include "presumption in favour of sustainable development".  They appear to rate wind farms as unsustainable while new housing on greenbelt is perfectly sustainable; we have so much green space that we can build on it now without limiting future generations ability to build on it too!

The Broomielaw

Image
The Broomielaw and the Tradeston Footbridge A long time ago, spring 2009 to be precise, Stephen Purcell, the leader of Glasgow City Council formally opened the Tradeston footbridge over the River Clyde from the Broomielaw on the North bank to Tradeston.  The new bridge formed the focus of a £33 million regeneration scheme for the area which involved strengthening existing quays walls to create an attractive public space. But not for long. At the opening Purcell said: “The Tradeston Bridge and the wider scheme to develop new public places will act as a catalyst for future regeneration of the Tradeston area.  It is important that the public purse continues to invest in the city’s infrastructure at this difficult time to bolster Glasgow’s economy and pave the way for future development along the Clyde waterfront.” This is where the conflict seems to come in: creating public spaces and bolstering the economy no longer appear compatible.

When the Wind Blows

Image
How the mighty have fallen - Mature tree in Pollok Park destroyed in December storms It has been fairly windy in Scotland over the past year. Back in May , unseasonable storms battered the country causing one fatality, power outages, travel disruption, damage to crops  and felling many trees.  We do not normally have such high winds during the spring and summer when the trees are in full leaf so they were more susceptible to damage and many mature trees were lost. The next big storm was in September when the tail end of Hurricane Katia brought heavy rain, flooding and more trees down. It was not nearly as severe as Huricane Irene that struck the north east US a couple of weeks earlier but it still caused at least one fatality and significant disruption. A relatively calm and mild but wet autumn followed as local government prepared for heavy snow like that which caught them out last year. Then came hurricane force winds on the 8th of December . They had been forecast a few
