For the next ten to 15 minutes I will give the committee a background on conservation agriculture because there can be a degree of misunderstanding about what is involved in the system. I will outline to the committee the significance of this system of farming on a global basis and the extent to which we in Ireland have fallen behind somewhat in recent years with regard to uptake of this system. Huge benefits can accrue from conservation agriculture, not just to the farming community but also to rural populations and society in general.
Conservation Agriculture Ireland was established in late 2002. We are an independent voluntary, not for profit organisation and our remit is to improve awareness and education on conservation agriculture. We maintain at all times the goal of economic and environmental sustainability in farming, which is of crucial importance. Our organisation is affiliated to the European Conservation Agriculture Federation. That federation brings together a network of 14 different organisations, both from member states and outside member states in the EU. We interact with those people in terms of research, development and farmer to farmer experiences.
Conservation in agriculture is crop production with minimal soil disturbance. When I say "crops" members might assume I am talking about wheat, barley, oats, oilseed rape, triticale or linseed. That is the case but it is also involved in grass production because when we receive grassland to improve our productivity on grasses, we sometimes plough to re-establish a new sward but we do not need to do that with this system. There is no ploughing and we adopt constant soil cover, where possible.
Conservation agriculture is not organic farming because we believe in the judicious use of pesticides and other inputs like fertilizers to enhance the yield potential of our crops. That is important because we can achieve significant cost reduction at farm level and my two colleagues here, one a large-scale farmer and the other a part-time farmer, have enjoyed these cost reductions. As a system, conservation agriculture has very positive environmental impacts and it is a truly sustainable system. Part of the Department of Agriculture and Food's mission statement is to put in place a sustainable agriculture.
Since the late 1980s there has been ongoing and increasing uptake of the system worldwide. Recent figures compiled for 2004 suggest that 80 million hectares are being used for this system throughout the globe. In Europe the situation is very different. The percentage of arable area under conservation agriculture is very small. In most countries it is below 5% and in Ireland it is below 0.05%. If we consider the percentage of arable land under conservation agriculture and examine the top seven countries worldwide, we see that in excess of 30% of those lands on average are devoted to conservation agriculture, that is, the production of crops without recourse to the plough.
Another aspect members might notice about these various countries — Paraguay, Argentina, Brazil, Bolivia, Australia, the USA and Canada — is that they do not have direct subsidies to farmers. Farmers adopt this system on a worldwide basis to remain viable and economically sustainable. More importantly, they have realised enormous environmental benefits.
Ireland's contribution to conservation agriculture development internationally comes in the guise of my colleague, Patrick Wall. He is now based in Harare, Zimbabwe. Last year he was based in Mexico where I visited him. He has received the order of merit from the Bolivian Government for his contribution to agriculture and environmental sustainability in that country. He is a colleague of Norman Borlaug, Nobel peace prize winner. In my discussion with Patrick Wall he told me that the subsidy system in Europe could be used to encourage farmers to change to conservation agriculture practices because everybody would benefit.
The story is different in Ireland. While we are increasing conservation agriculture in terms of uptake, the green bars on the submission refer to winter crops and the orange ones refer to spring crops. We have seen ongoing increases since the year 2000 up to this year but in terms of uptake we are still under 12,000 hectares. Our arable area is in excess of 375,000 hectares.
Teagasc has been researching the system in depth from 2000 to date. Tony Fortune will be able to provide the committee with details of that research should it wish to have further data. In 2000, it examined machinery performance, soil physical, chemical and biological properties, nutrient leaching and greenhouse gases. That research is continuing to date. In 2001, Teagasc introduced studies on fauna, earth worms, slugs and aphids and the impact of the system on those different species. With respect to flora, it examined weed species and populations. Those studies are ongoing.
In 2002, Teagasc started research on cover crops and interactions with spring crops. That is of vital importance because cover crops are hugely important in South America. In the state of Parana, in southern Brazil, an area greater than the size of Ireland is devoted to cover crop production annually, in conjunction with cash crops. They use the cover crops to build up fertility in the soil, reduce weeds and pest species and allow the soil be ready for the subsequent cash crop that is introduced.
Teagasc is looking at greenhouse gas fluxes, carbon dioxide, nitrous oxide and methane. It is also examining changes in soil carbon. That is extremely important because we are talking about carbon sequestration — the fixing of carbon in our soils. As members are aware, that is one of the goals and objectives under the Kyoto Protocol.
Thirty years of international research provides the following findings. For the farmer, and this is the case throughout the world, we see reduced costs, reduced labour, reduced diesel usage, reduced crop inputs and it is a simpler system to use once the skills are developed. More importantly for us, the public and public representatives, there are enormous benefits for the environment and society. These are the results of the research obtained.
We have reduced carbon dioxide emissions; less nitrate and phosphate leaching into waterways; less silt contamination of waterways; less pesticide run-off; reduced soil erosion; increased organic matter; improved soil structure; and increased biodiversity. Those last four points — soil erosion, organic matter, soil structure and biodiversity — come under Article 5 of an EU regulation and various directives. This is from work done in Kilkenny from 1989 by Michael Neill of Inland Waterways, now the Environmental Protection Agency. We are looking at five river catchment areas. Beginning in the bottom left hand corner is the Shannon. Moving up to the Burren area in the top right hand corner — that is Jim McCarthy's area. There is a direct correlation between the percentage of land area ploughed and the nitrogen lost to waterways.
With regard to conservation, agriculture and wild birds, environment directive 79/409/EEC provides that we must improve and maintain the habitats for wild birds in our agricultural communities and rural areas. This chart shows work done by Alastair Leek in the UK as part of the linking the environment and farming research project there. Across four species — the skylark, the tree sparrow, the chaffinch and the yellowhammer — there was a dramatic increase in numbers where conservation agriculture was practised in comparison with plough-based agriculture. Ours is an all-Ireland body and one of our members, Clive Weir, from County Down has recorded the highest number of yellowhammers in the British Isles on his farm. An ongoing research project has been taking place on that farm by the Royal Society for the Protection of Birds.
The forest at the back of my house in Tipperary is a natural forest. Every year we see leaves fall from the trees and a flush of growth in the spring time when new leaves grow. There is no input or interference from man. At the base of the forest floor there is constant soil cover and there are high organic matter levels as exemplified by the fungus that is growing on the forest floor. What relevance has this to agriculture? In this picture we see a tillage field near Kildalkey in County Meath. This was previously a crop of oil seed rape. The plants members see growing are old rape seeds that fell out at harvest. However, members can also see mushrooms growing in the area, which are indicators of high organic matter.
What is the practical benefit for the farmer from this? He can drill his crop direct into the soil. He does not need to cultivate or to plough. This farmer has switched from plough based to reduced cultivations over a three-year period. Next year he will not plough any of his land. There is another net benefit of particular importance to society. This picture shows the same field two years apart. Members can see the haybarn in the background. On the left hand side, under water, there is a plough-based field. There was heavy rain in October and November 2002. Two weeks prior to that photograph being taken, there were 4.3 inches of rainfall. In November of last year there was an equal period of heavy rainfall when there were 4.1 inches in two weeks. Where is the lake of water in the photograph? As a result of improving the soil and its structure, we have improved the inter-relationship between rainfall, water infiltration and the build up of ground water supplies. It is clean water because it is sieved through the soil profile. In the left hand picture there is surface water run off and contamination of waterways.
The truth about ploughing, even though we are not prepared to face the fact at times, is that it is not necessary for crop production or weed control. It costs money and makes farming uncompetitive. It reduces organic matter in the soil and destroys soil structure. Ploughing can lead to soil erosion. This is a direct violation of good agricultural and environmental conditions as instanced by Article 5 of Council regulation EC 1782/2003.
Other member states have seen the light. I am now showing information from the Federal Republic of Germany. We are looking at subsidies for conservation agriculture in four federal states. Subsidies range from €25 to €115 per hectare to reduce sediment run off and soil erosion and to maintain constant soil cover through the use of cover crops over winter months. This funding comes from the national exchequer, not Europe. Local governments in these federal states see the environmental benefits of these systems and are prepared to put their taxpayers' money into promoting uptake and adoption of the system. This happens also in Portugal. Under different schemes there are subsidies, from the national exchequer, ranging from €26 to €69 per hectare. I can show similar slides for France, Switzerland and the Netherlands.
Our delegation is here today to ask the committee to consider the following. We can, through the judicious use of European subsidies, put in place arable grassland agriculture that is economically and environmentally sustainable. With regard to tillage, we could ring fence modulated funds from the tillage sector. We can promote economic and environmental sustainability at farm level. Farmers who practise or adopt conservation agriculture could be encouraged and supported using modulated funds. Graded support could be given for reincorporating straw to build organic matter in the soil; for direct drilling or no tillage as it is called; for reduced or minimum tillage, which over 100 farmers in Ireland are practising at present; for the use of cover crops in conjunction with spring crops — using cover crops over winter to protect the soil, reduce weed competition and pests attack and to keep the soil open in readiness for the subsequent sugar beet, spring oil seed rape, spring barley, spring oats or spring wheat crop.
Ireland's agricultural policy needs change. We do not need to simply give handouts to farmers but to put in place an agriculture that is sustainable economically for farmers such as Jim McCarthy, so he will be able to compete in 2010 and beyond, and Bartie Cash, who is a part-time farmer so he will be able to maintain his lifestyle of doing part-time work and engaging in tillage production. We must change our mindset. Members of the committee are free to ask questions about my presentation. I firmly believe that this is the way forward. We have seen it happen in other countries where farmers do not receive subsidies. We should try to get where the ball will be, rather than have to chase the ball all the time, like under-12 footballers.
