climate change and farming in Ireland: part 2

In November, Minister for the Environment John Gormley said that �all sectors will have to cut emissions�. According to Minister for Agriculture, Fisheries and Food, Brendan Smith TD, �making significant cuts from agriculture will be very difficult�.
He warned against �significant downward pressure on animal numbers, something that would �in a global context make no sense�.
The Minister said that if Ireland was to reduce cattle numbers, the global climate change situation would actually be worsened because "Irish beef would simply be replaced on world markets by beef produced in a much less sustainable way".
This point of carbon leakage has been raised in many quarters. Essentially the suggestion is that if we stop producing, other less sustainable regions in the world will instead. This will increase rather than decrease overall GHG emissions.
Department of Environment representative, when queried, claimed that �there is no confusion between this Department and the Department of Agriculture on greenhouse gas emissions from the agriculture sector.�
Simple and straightforward. And yet, there since the EU targets were agreed, there has been a rumbling on going discussion on footing the GHG bill. Enough to remind one of Queen Gertrude's most famous line: 'The lady doth protest too much, methinks'.
What has been dubbed the 'cow tax memo' suggested, according to reports, that �imposing a levy on all livestock is the best way to avoid having to cut the size of the national herd�.
This memo proposes a levy set at �5 per tonne of CO2 emitted, to generate just over �100 million. This has been reported as an equivalence of a levy of �13 for each dairy cow, �7 for non diary cow, �1 for sheep.
Minister Brendan Smith and even the EU commission have all come out railing against the possibility of this cow tax.
According to former Green Party leader, Minister of State Trevor Sargent, who's brief also includes cattle breeding, �A myth has been peddled however claiming Minister for the Environment and Local Government John Gormley T.D. is in favour of a cattle cull to reduce methane emissions. This is completely untrue and is a gross disservice to the work Minister Gormley has been doing to help the long term viability of all sectors, including agriculture�.
He points to two crucial areas his colleague has achieved for Ireland and agriculture with regard to climate change: In the European climate change deal agreed before Christmas, �Minister Gormley ... achieved flexibility in the deal to ensure that Ireland did not face higher costs of reducing greenhouse gas emissions, and that we would not be forced to reduce our national herd�.
Gormley �also met with the European Presidency�s chief climate change negotiator, and was successful in having carbon leakage placed onto the agenda for future climate change negotiations�.
Just how much agriculture should pay is an altogether more interesting question in a contracting economy.
While demand for higher end food products may reduce abroad, it is likely that agriculture, which already provides 32% of net foreign earnings, will become more prominent in the future. Ireland have various practical advantages in producing food (e.g. climate, access to markets) which do not pertain in most other economic sectors.
According to Dr Mary Kelly of the EPA �The profile of greenhouse gas emissions in Ireland is unusual in the European context, with agriculture currently accounting for 27 per cent of all emissions and 40 per cent of emissions in the non-trading sector. This makes it very difficult to effect actual reductions on the scale required in the non-trading sector�.
The Koyoto targets, it seems, might be reachable due to recession. However the EU targets will prove far more difficult. Climate change experts have predicted that Ireland's' emissions will be down by between 5 and 9% in 2009, because of the recession.
Frank Convery, professor of environmental policy at University College Dublin, was reported recently as saying that Ireland's emissions may well be as close to the 63 million tonnes permitted under Koyoto. This would save the government E300 million in the purchase of carbon credits.
A recent EPA report, issued in March of this year, considers different scenarios, including that of economic shock until 2010 � decline by 7% each year until 2010, and then growth until 2020.
According to the EPA report, irrespective of economic performance, there is only one scenario for agricultural emission projections:
�Emissions are projected to decrease by 4% over the period 2007 � 2020 to 17.8 Mtonnes of CO2e.� This estimate was actually 18.95 Mtonnes in 2008, so agriculture is performing even better than just last year's predictions from the EPA itself. Agriculture in 1990 accounted for 35% of emissions.
Individual sectors performance within agriculture underscore this fact: According to Dr Gerry Boyle of Teagasc �Technological advances in dairy production, for example, have led to a drop of 12.4% in the amount of methane produced per kg of milk between 1990 and 2006�.
Most GHG emissions from Irish agriculture are methane from livestock and nitrous oxide from soils.
Specific measures under the Rural Environment Protection Scheme (REPS) �are expected to raise awareness amongst farmers of the need to address climate change and also to promote greater acceptance and uptake of technologies that contribute to greenhouse gas abatement, such as use of minimum tillage and the adoption of low emission trailing shoe technology for slurry spreading� a DAFF spokesperson said, when queried.
Other abatement strategies include: dietary modifications, additives or probiotics to reduce methane production, breed selection, increasing the length of the grazing season and breeding more efficient animals.
The spokesperson also pointed out that the nitrates directive had resulted in �better use of nutrients with consequently less nitrogen application and therefore fewer nitrous oxide emissions�. This includes matching nitrogen use to soil type, increasing clover use on farms, use of nitrate inhibitors�.
It was also suggested that �in terms of reduced fertiliser use and consequent emissions, organic farming will also have a role to play and is supported through the Department of Agriculture Fisheries and Food's Organic Farming Scheme.�
Forestry and energy crops are also relevant. To encourage energy crop cultivation, the National Energy Crop Premium (E80 per hectare) was introduced in 2007 to supplement the EU Premium of E45 per hectare.
A new Bioenergy Scheme was also launched offering establishment grants worth E1,450 per hectare to plant willow and miscanthus. Land planted with energy crops can also benefit under the Single Payment Scheme as well as REPS and the Disadvantaged Areas Scheme, subject to some restrictions on the areas planted.
The main issue from a farming perspective is, according to Gerry Boyle, �Gaining credits for afforestation and biomass production for bioenergy is problematic�. However, �there is no basis in logic for the agricultural sector not benefiting in accessing these offsets given that it is farmers that will need to alter their land use practices�.
However, there are other laggard areas. Gary Lanigan is a Teagasc research officer based in Johnstown Castle. His area of speciality is emissions, including GHG emissions, and soil carbon content.
According to Lanigan, while fertilizer usage is down down 20-25% from 1998, and while sheep and cattle numbers are down too, he estimates that �Only about 1% of farmers are using clover�.
Considering the numerous cost and environmental benefits, this is an astounding figure.
There are many considerations in the debate on GHG emissions. A complete and comprehensive life cycle analysis might skew all the figures again: While the application of fertilizer produces GHGs, so to does the making of fertilizers.
A nagging worry of course is the possibility that the scale of the problem and the scope of the solutions simply do not match up.
In the meantime, matching efficiencies and emissions, and seeing opportunities in the constraints may help agriculture move forward sustainably.

farming's future sustainability
Here's an interview I did with Richard Douthwaite (right) of FEASTA. It appeared in last week's Farming Examiner as the front page and centre page spread.
Oliver Moore: Can you outline the overall situation with regard to the sustainability of farming, as you see it Richard?
Richard Douthwaite: Modern industrialised farming, particularly tillage, has been described as a way of converting fossil energy into food energy. There�s a lot of energy used in the application of fertilizer, in tractors, in sprays, then in packing and getting the food to the customer. The whole process is not sustainable. In traditional forms of farming, it took 4 units of energy to produce each unit of energy in food. Most of that energy was directly from the sun, and all from renewable sources. Now there are 40 units of energy going into the production of food in the Europe, and perhaps up to 90 in the
OM: Within this broad picture, what is the key problem?
RD: The problem is that we�re not recycling the nutrients. Quite a lot of the nitrogenous fertilizer breaks down in the soil and becomes nitrous oxide, a powerful greenhouse gas (GHG), and one of the main sources of GHGs in farming. A lot of energy is used in the production of those nitrogenous fertilizers and most of it is wasted because the nitrogen is not taken up by the plants. There's more waste when the crops leave the farm because the nutrients they contain aren�t recycled: There�s nitrogen in the proteins that go off, and there�s phospates going off too. They are consumed by whoever eats the food and go into the sewage system, and don�t get back onto the land. As a consequence of this, we need to apply more artificial fertilizers. There is a growing problem with phosphorous. There�s a finite supply: rock phosphate is getting scarcer and scarcer, and that then means that more and more energy is needed to make it available to us and to transport it from places like
So we need to think of how fertilizer can be better retained in the soil, so that if you are putting nitrogen on, it stays there. We need to minimise the use of artificial nitrogen, and to start replacing it with organic sources, such as legumes which fix nitrogen. Then, we need to make sure that any that escapes is recycled.
RD: Agriculture is likely to become more labour intensive again. The trend towards the larger farms will be reversed as the cost of food and fuel rises in real terms and takes a higher proportion of non-farmers' incomes. Farmers won't just be growing food. They will be producing fuel, chemicals, fibres and building materials as well. A whole new category of multi-purpose crops will emerge.
RD: It may emerge in a way similar to the co-op creamery structure of a century ago, where the co-op would take the milk and the farmer would take back the whey. I envisage a co-op bio-refinery in each community to which farmers would deliver crops like miscanthus, which would be refined to give protein powder, biogas, diesel fuel, plastics like nylon, pesticides and soil improvers. The farmers would take the improvers back to their farms to recycle the nutrients that were in the crop they delivered to the refinery. Because transport will become more expensive, the plants' bulk will be reduced in rural areas and there will be centralised refineries regionally that take the valuable bits and process them further. At the bioenergy show in Tullamore this year, miscanthus was being sold in compressed blocks for people's fires, just like the wood blocks made from compressed sawdust. But 20% of dried grass is plant protein � that�s too valuable to burn. Quite simply, we should be taking out the valuable bits before burning any biomass.
RD: Yes, but I should emphasise that these would be second-generation biofuels, produced by breaking down the cellulose found in all plants. Feasta is very much against the production of most first-generation biofuels, such as ethanol from maize and wheat and biodiesel from oilseed rape. These make no sense from an energy or a climate point of view. Their production is entirely driven by tax-breaks and the net result has been to increase hunger around the world. The only first generation biofuel that is acceptable is ethanol from sugar cane in
RD: If farmers can increase the carbon content of their soils, or the semi-permanent biomass that�s growing on them, they need to be rewarded in some way for doing this because they would be helping prevent climate change. Part of their reward would be that they made their soil much better. It is however, very difficult to measure the carbon content of soils to pay farmers a set amount per tonne for the carbon that they have taken in. Feasta is therefore setting up a working party to develop a new concept of best practice - to develop a better understanding of the types of farming that involve sequestering more and more carbon in the soil or in the plants growing on the soil. It needs to become financially beneficial to follow best practice. There could be payments through REPS, or the price of the crops could be subsidised in some sort of way. We�re going to need people in the working party with expertise in this area, and we�re getting very good co-operation from the universities and from Teagasc on this.
RD: Feasta has become particularly interested in the inclusion of charcoal in the soil. It has recently been discovered that the pre Columbian Indians put charcoal into the soil because it held the nutrients there. Also, there was an increase in microbial and fungal activity which made the soil more fertile. These soils still exist in the Amazon basin where they are called terra preta, which means dark earth. What happens, it seems, is that the fungi feed on sugars sent down by the plants, and they in turn send up nutrients to the plants. So the plant sequesters carbon too. Terra Preta promises to do three things: 1 sequester more carbon in the soil; 2 hold nutrients there more efficiently; 3 give bigger crops.
RD: We don't think there should be a debate at all. Some civil servants seem to think that because cows' digestive systems give off methane, a GHG,
RD: Methane is a very serious GHG. It�s probably 60 times worse than CO2. Official figures suggest that it is 23 times more, but that�s over a 100 year period. However, all its heating effect is concentrated in the first few years before it is broken down. But - and this is crucial - the carbon in the methane released by cows comes from natural sources. It is not adding continuously to the carbon in the air, because the plants that the cows grazed on picked up the carbon from the air. So the cows are part of the natural carbon cycle. They are not leading to a net increase in the warming effect. If you increase the size of the national herd, you get a once off increase in methane; you don�t get a continuous increase in CO2 levels, as you do if you are burning fossil fuels in a car. So there is no comparison at all between cars and cows.
RD: If meat and milk is to be produced anywhere in the world, Ireland should be one of the places producing them because the fossil fuel emissions from producing them here are lower than they would be almost anywhere else. You've also got to consider the carbon emissions if forest is cleared for beef production in places like
RD: Yes, I think so. But many more cattle will be kept indoors so that the slurry can be turned into biogas. This will be used for heating, for electricity and compressed to run vehicles. Farmers have been very slow to realise that the energy content of a bullock's dung is worth more than its meat.

Training opportunities in the organic centre, rossinver
Interested in training in an aspect of organic farming or growing? Or are you interested in learning more about how to make your life more sustainable and self-sufficient? Then have a look at the Organic Centre�s 2008 course and training programme.
According to Hans, there is plenty for people interested in becoming a full time commercial grower: �we have a one year FETAC level five course for those interested in professional organic growing.�
�We�re also working with the new NATS organisation, the National Organic Training Skillsnet, formerly the Western Organic Network, and together we offer courses for commercial growers. These are for people who may be already in production, who want to diversify, upgrade their skills and son on. These include a seven day commercial horticultural course starting on Monday 18th February, protected cropping on 26th February, Orchards on 11th of March, medical herb production in April and organic salad production with Jim Cronin in Clare in June�
Their programme also lists a course that can be done on individual days, or in one, five or 10 day blocks, called The Complete Organic Garden. This starts next Saturday, February 2nd.
As well as these courses, there are courses on cooking - one that caught my eye was �cooking by your blood group� with Dr. Prannie Rhatigan, a public health doctor; others include cheese making, gourmet mushroom growing, bread making and the like. While some of these could lead onto commercial enterprises, the Centre retains a focus on what could be termed a self-sufficient well fed lifestyle.
Then there are the small scale renewables courses, the arts and crafts courses and more again that are difficult to categorise. Sustainability includes energy conservation, sustainable house design and construction, reed bed systems; the arts and crafts includes silk painting, willow sculpture and micro hydro power generation. The novel, quirky one that most stood out for me was, without doubt a course on The Planning Process - a Layperson�s Guide to Supporting or Objecting to Planning Developments.
A classic catch all course on offer is called How to Live the Good Life, which does exactly what it says on the tin: it offers life skills over five days in growing vegetables organically, growing and using herbs, growing fruit for the home, making yoghurt and soft cheeses, baking and cooking with wholemeal and storing and preserving, introductions to yoga and relaxation techniques, sustainable building, a seaweed walk on a local beach and a visit to a local organic farm.
According to Hans, the Good Life course is moving from being a hobby course into a slightly more business-focused, skills course. �People have started to learn how to be more efficient and conscious, so its now more a survival skills course. People have starting using this course to also make a better living on their enterprise, over the five years its been running.�
With all of this going on, I asked Hans if �Organic Centre� was a bit of a misnomer as a name: there are so many courses in what could be called the non-commercial growing area on offer. �I suppose it is. We have changed our subtitle, which used to say training and education in organic growing and farming. Now we�ve added sustainable living.�
Indeed they have.

oil and Ireland's coping strategies: that $100 moment
Don't worry foodies, there's plenty on food in it! I do regret not including the following things, however, so I'm glad to be able to include them now:
best place for info on peak oil is probably: this place! http://www.feasta.org/
John Gormley also obviously introduced the VRT changes and the lightbulb changes
and decoupling in Irish Agriculture has reduced the emissions from agriculture.
So here is the article:
With globalisation has come global sourcing of foods and agri-food inputs; we in
According to the junior minister with responsibility in the area, Trevor Sargent, there are less than a dozen large scale vegetable producers left in
Just-in-time deliveries by road mean that supermarkets have jettisoned their storage spaces and instead opted for storing food in refrigerated trucks on the roads. Food processing is ever-increasing too � both involve more oil.
So, seeing as we are so dependent on it, how much oil is left then? That depends upon how you measure it. For example, optimists suggest that there are bound to be reserves. According to the
�Those who believe a peak is imminent tend to consider only proven remaining reserves of conventional oil, which they currently estimate at about 1.2 trillion barrels�this is a pessimistic estimate because it excludes the enormous contribution likely from probable and possible resources, those yet to be found.�
So what is
The new Energy Minister, Eamon Ryan has begun to put some mitigating factors into place: these include funding for renewables research, the smart electricity metering programme for houses which will be rolled out in April, and improved north south energy co-operation. A National Energy Efficiency Action Plan is being finalised at present, which according to the Minister, �will allow us to save �1.7 billion or 3 million tonnes of oil every year.�
Minister Ryan states that �We are also committed to making energy efficiency savings of 20% by 2020. The public sector will have to make energy savings of 33% by this date.�
In Kinsale, students from the 2 year permaculture course in the local college along with their then teacher, Rob Hopkins, designed an energy decent plan, which has received some funding from the local council. The plan goes through all the key aspects of socio-economic and cultural life in Kinsale, and produces a road map for how to reduce energy use.
�We didn�t think it was going to be that big a deal, but the plan has been downloaded over 5000 times around the world� according to Klaus Harvey, who sits on the Steering Committee of Transition Towns Kinsale. This plan has become an intergal part of what has become the known as the transition towns movement. For Kinsale, food, education, housing, economy and livelihoods, health, tourism, transport, waste, energy and marine resources are all examined and mapped out in energy decent terms.
In north
And it�s not just the ecovillage itself. �The ecovillage is a partner in a European project called SERVE - Sustainable Energy for the Rural Village Environment. This is providing over �2 million in funding for the area around Cloughjordan to improve energy efficiency in existing houses and expand the use of renewable energy. This will cover such additions as more insulation, double glazing, solar panels, wood pellet boilers and better central heating controls�.
Is it all enough? In the final analysis that depends upon whether we resist or embrace change.
Tuesday, March 6, 2007
A recent DEFRA report, conducted by the Manchester Business School, has grabbed some headlines for claiming to prove that organic food isn�t always better for the environment.
A clear headed reading of the report reveals that most organic meats and wheat have lower energy uses, and all organic products have lower or no pesticide uses.
However, most media that have covered this story seem to have latched onto the fact that some of the time, some environmental impacts of some organic foods are considered higher than is the case for some conventional foods.
For example, much has been made of organic milk�s negative environmental contribution. However, if you read the report, it is clear that the energy used to produce 1lt of organic milk is less than half that used in conventional milk.
Where organic milk falls down relates (in an unspecified way) to the type of feed used by organic producers in the UK. In a context where certification means maintaining organic all the way from production to consumption, sometimes products and inputs have to have to be moved long distances. A more local conventional source may sometimes be available, but then the consumer doesn�t get a certified product.
This is always an issue for organics, and does obviously contribute to food miles. However, the question has to be asked � what�s the alternative? It is likely that with the increase in organic consumption, more products, inputs and services will be available in more and more places, thereby reducing the carbon footprint of these organic foods. The alternative to supporting organics and waiting for this to happen is to support conventional, with all its myriad environmental problems.
But in many cases, the research is, in my opinion, limited or flawed in a number of ways.
It is limited in not considering the farm as a place where the environment actually is. It�s as if there are farms, and there is the environment, and both are separate entities. In this flawed methodological construct, the lands used up by organics to produce food makes organic seem more damaging.
However, it is possible to view this construction in an entirely different way. Organic farms have been proven in numerous reports to be higher in biodiversity levels than conventional farms. So there is more nature in, or on, organic farms. There is more biodiversity in terms of farmed products and more in terms of plants in fields, life in hedgerows, birdlife and so on. Conventional farming has done enormous damage to biodiversity levels over the past 60 years.
Despite its stated focus on sustainability, this report does not consider biodiversity, animal welfare, soil condition or (in a comprehensive sense) water usage, so the report cannot be considered all-encompassing.
The UK�s Soil Association also claimed that the model used for the study amplified the amount of nitrous oxide emissions, while also increasing the land area used by organics by half.
Some good points are made, however. Car transport to and from supermarkets has a more negative effect on the environment than much food production. Interestingly, sometimes local production, even of organic, can be more energy intensive. Tomatoes produced in heated UK greenhouses have a greater negative impact than those produced in unheated ones in Spain.
So it all comes back to thinking about what you eat. If the product is out of season, and produced nearby, a lot of energy has probably been used to do this.
For all its flaws, it is clear from this report that the move towards agri-industrialisation in organics has had some inevitable negative impacts: the spirit of organic suggests more natural feeds and less concentrated feeds for animals, more crop rotations and less liquid feeds and so on. If you are lucky enough to know organic producers working in these more natural ways, make the most of them.
Overall, the three amigos � seasonal, local, organic � need to form a holy alliance. And in a choice between giving up because organic certification sometimes results in extra transport, and working toward a food system functioning with an awareness of the benefits of combining local, seasonal and organic, I know which one I�m choosing.

This week in the Examiner, I'll be both highlighting and critiqing aspects of a report commissioned by DEFRA, conducted by the Manchester Business School. The report focuses on sustainability and food provisioning, with a particular focus on energy.
Some good points made, but plenty of errors picked up by various anti-organic truffle hounds....
The article will be more factual than theoretical, pointing to various misreadings out there and mistakes in the research itself. However, there will also be a focus on the salience of combining seasonal, local and organic, otherwise even local organic food can leave a heavy footprint (see also embedded food miles).
Theoretically, one of the main criticisms will be the conceptualisation of nature and the farm as two completely separate things...
The farming supplement of the Examiner is out on thursday....why not prepare for the article?
