This blog was originally based on a course ran by Professor Nick Gray of the Trinity Centre for the Environment at Trinity College Dublin who also wrote a textbook for the module Facing up to global warming: What is going on and what you can do about it. Now working as an independent consultant, Nick continues to work in the area of environmental sustainability and looking at ways of making a difference without recriminations or guilt. Saving the planet is all about living sustainably.

Living Sustainably Course 2013: Defining Sustainability

This year’s Living Sustainably course (BCBOT) started on Monday and each year students are asked to write a personal definition of sustainability in no more than 50 words.  Last year’s students wrote some amazing definitions, many of which were posted.  To mark their achievement and to give our new students some inspiration you can download the complete list from last year here.

Watch out for new definitions which will be posted over the coming weeks.

Bill Gates on Zero Carbon Energy

Bill Gates presents an interesting TED talk about the need to develop alternative energy sources to develop Zero carbon emissions globally by 2050.  The thing that comes over for me is the need to set a realistic and fixed price for carbon emissions to stimulate the type of research that we need right now.

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)
