Review: Fundamentals of Sustainable Development by Niko Roorda


There is an ever increasingly large number  of books on the market dealing with sustainable development, so any new book has to offer something new.  Fundamentals of Sustainable Development By Niko Roorda published under the  Earthscan imprint by Routledge (2012) offers just that in a very innovative way.  It goes against the trend of specialization within the area of sustainable development, which often creates inaccessible and  to my mind overly confusingly complex views, but gives a fresh approach to understanding the problems and to some extent the solutions to the crisis facing us today. Roorda describes the crisis in the develop world as the triple crunch  (i.e. climate change, economic crisis and oil depletion), which illustrates his no nonsense approach.

The book is broken down into two parts. Part I is called SWOT analysis (i.e. strengths, weaknesses, opportunities and threats) which explores the global situation. This is made up of four chapters: 1. Sustainable development: an introduction; 2.  Flaws in the fabric: people and nature; 3. Flaws in the fabric: people and society,; and 4. Sources of vigour, this later chapter dealing with global strengths.  Part II is Solution Strategies and  explores some of the ways in which sustainability can be achieved through a further four chapters : 5. Here and there; 6. Now and later; 7. Climate and energy; and 8. Sustainable business practices.  Based on case studies and littered with other examples and colour images  this is a fascinating book  and is as complete a text as I think could have been achieved.  It has numerous student questions which, with the support of an equally innovative and exciting website (www.routledge.com/cw/roorda), makes this text very interactive.

The book really is interdisciplinary, and while challenging in places is truly accessible to readers of all backgrounds.   The presentation of the book is excellent and the format makes this a very attractive paperback, and at 350 pages, it is not too big for students (and lecturers) to carry around. This is a colourful and intriguing textbook which I highly recommend.  It is the sort of book you wish you had written yourself, but Niko Roorda has done just that and in the process added a remarkable edition to the sustainability library.

Lucy Siegle - Ethical Fashion



Lucy Siegle is the author of a very interesting and challenging book ‘To Die For: Is Fashion Wearing Out the World.’
I think that the relationship between fashion, global economy (especially in the poorer areas of the world) and greenhouse gas emissions is a fascinating one.  It isn’t just about sourcing better and more sustainable fibres, it is the way we actually use and perceive  fashion in our everyday lives.  
Here is Lucy Siegle being interviewed for Chic Chat (shown onTHE OUTNET)

Organic food : Is it the sustainable option?

The term organic is often used as an alternative for the concept of sustainable, but is this really true.  There is no doubt that organic food is grown by people who care about the environment and work their land to strict conservation principles , but is it really best for the planet overall?  Organic farming has made an enormous contribution to altering farm practices and raising public awareness, especially in relation to biodiversity and conservation issues. Indeed many of the underlying principles of organic farming are now seen as best practice. So why is organic farming having such a bad time?
Sales of organic food has been falling in recent years and in 2011 it fell 3.7% in the UK alone with the number of producers also declining by a similar amount to just under 7,300.  This is in stark contrast to the ethical trading certification products such as Fairtrade whose have steadily risen over the same period with a 12% increase in 2011.   There are three reasons why people buy organic. The majority believe it is healthier (52% ), next come better animal welfare standards (34%) and a similar number buy organic because they believe it to be a more ethical way of farming (33%).
So what has changed? Quite simply consumers interested in sustainability are using different criteria in buying food such as is it in season, is it local, does it carry an ethical trading label such as fairtrade, and have welfare issues been addressed.  I must admit to being confused at some organic farmers markets where I have been confronted by out of seasonal vegetables, exotic fruit and vegetables that clearly all have large air mile tags attached.  Also authenticity is also another problem, especially with the price premium attached to many of these products sold in such markets.  A carrot looks very much like another, and with it now proven beyond a shadow of a doubt that organically grown is not really better than conventionally grown fruit and veg in terms of health or  taste, then we have to reassess the role of organic farming in terms of sustainability and supply the growing demand for food. The oft quoted WHO  estimate that 3 million people are hospitalized annually due to pesticide poisoning has been shown not to be relevant , as the trace pesticide residues found in conventional food, according to the Food Standards Agency in the UK, poses no risk to health.
Welfare of animals is normally higher with certified organic farmers, however there is sometimes a conflict between using proven chemical intervention (e.g. antibiotics , anti-inflammatory drugs and anthelmintics) and maintaining organic status.  In the UK antibiotics are allowed to be used by organic farmers in certain circumstances but largely banned in the US.  Farmers may be in a cleft stick, where necessary chemical intervention on welfare grounds could lose them their organic status.
Is organic farming sustainable? Probably not in terms of being able to  feed an ever increasing global population. Professor John P. Reganold in a recent article in Nature demonstrated that in developed countries organic farmers are achieving up to 20% smaller yields compared to conventional farmers which offset financially by charging a premium for organic produce.  In developing countries most organic fruit and vegetables are exported which brings  severely needed overseas currency into the country, but creating food scarcity within often highly productive areas.
Organic certification standards are excellent in Ireland and the UK but do vary widely between countries and the certification body, some of which may cause significant confusion to the consumer. So very often the consumer is unaware of exactly what they are buying.
So in terms of sustaining and promoting  biodiversity as well as protecting landscapes then organic farming is clearly advantageous over conventional farming, but the majority of farmers are now aware of the importance of these issues are responding by using a broad range of conservation techniques.  In terms of greenhouse gas emissions going the organic route may not be all that it seems. Certainly soil fertility and quality improves under organic regimes, but research carried at Oxford University suggests that while pollution per unit area of land farmed is lower than for conventional farming, it is generally higher per unit of food produced

But the four tenants on which the Soil Association is based i.e.  health, ecology, fairness and care,  are now increasingly at the heart of conventional farming as well.   To this effect the Soil Association are now working with non-organic farmers which appears to be a sensible development for sides of the farming lobby.  So should we buy organic? If it locally sourced and seasonal then it is preferred by me, but cost will always be a factor as is the need to develop farming to meet the challenges of climate change and increased food demand.

Incredible Edible - Personal action at its best



Can the individual or community make a difference…you bet you can.  One of the many examples is the Incredible Edible initiative which was started by a group of volunteers in Todmorden in England who turned plots of unused land into communal vegetable gardens.  The video below is a presentation given by Pam Warhurst the co-founder. The idea has gone global with similar projects on every continent. Watch and see just how individuals can make a difference.


“I wondered if it was possible to take a town like Todmorden and focus on local food to re-engage people with the planet we live on, create the sort of shifts in behaviour we need to live within the resources we have, stop us thinking like disempowered victims and to start taking responsibility for our own futures." (Pam Warhurst)

“There's so many people that don't really recognize a vegetable unless it's in a bit of plastic with an instruction packet on the top.”  (Pam Warhurst)

Waste Storage Efficiency


I feel that improvement should be given on the recycling of household plastic and metal materials such as bottles, cans, etc. A problem with storing these materials for appropriate recycling is that they take up a lot of space in the home if not compressed properly, thus the containers they are kept in can overflow very easily, which not only discourages people from maintaining them for recycling, but also, for many, results in frequent visits to the recycling units.

Compression of recyclable material would allow more to be stored efficiently

However, if households were to contain a small yet strong compressor for these materials in order to flatten them completely, more of them can be stored between recycles. The amount of carbon emissions which would go into making these handy compressors would thus be returned by the increase in waste material recycled appropriately and the reduction of recycling trips required. This means that excess material would no longer have to be inappropriately discarded until enough space has been freed-up to dispose of them properly.

iCar or weBus?



Does the accentuated presence of the I in society cause unethical transport choices?
I have always believed Public Transport is a good choice for the environment. However, recently it dawned on me that this is only the case as long as ‘we’ are many who choose this option. In Dublin so few people are now opting for taking the bus, that it is more energy efficient to travel in a personal car with a driver and one passenger, than it is to take the bus...

I must here warn the reader that the following is to be thought of as a discussion queue on the subject of citizenship and public transport, not as a contribution on carbon calculations. Currently the most commonly registered car in Ireland has a B Band engine capacity which is estimated emitting around 140g CO2/km (Link). Divide this emission figure by two (driver plus one passenger), and it gives us around 70g CO2/passenger km. A Dublin bus with 90 passengers emits about 1,450g CO2/km (‘Surprise carbon offenders’, Link ). This would equate to around 16g CO2/passenger km if the bus had a constant of 90 passengers. However at current usage the emissions using Dublin bus is an unimpressive 77g CO2/passenger km (Link). Using this information, estimation calculation tells us that if we want our public bus service to be more energy efficient than a B Band car with a driver and one passenger, then we have to ensure that there is on average a minimum of 21 passengers per Dublin Bus at all times (1450/70).

Without shying away from the fact that the public transport system may need to change numerous aspects of its current service to make this more appealing, my question for the forum is not in terms of how Dublin bus can please us. It is rather philosophical in nature and asks if it is ethically sound to always embrace the ‘personal choice’ theorem? If the bus transport service in Dublin is losing some of its viability as a sustainable transportation method due to insufficient number of passengers, then is there an argument for public transport to be formulated more as a ‘citizen obligation’ for the better of the ‘we’, rather than as a ‘service’ available at the leisure of the ‘I’?
