Back to the future: Multi-functional farms with climate and biodiversity benefits
'We lived off the land for centuries and then we lived off oil for a few decades which was an aberration in our history. Now, living off the land will be the new normal again,' says Dr Wouter van Winden, chief fermentation scientist at the multinational firm DSM-Firmenich.
He was speaking at the Finding Common Ground festival at the RDS in Dublin recently. At the event, policymakers, academics, farmers and landowners spoke about finding new opportunities for, and more value from, Irish land.
It took place against the backdrop of the Land Use Review, phase two of which has been completed. When it is made public, the review will offer suggestions on future land use in Ireland. Phase one, completed in 2023, gave baseline figures on current land use in terms of the types of agriculture, forestry and associated areas.
The bigger picture involves a realisation that land can no longer be seen solely in terms of food production, but instead with multiple roles in an interconnected system.

Land has multiple potential uses when you consider the broader bioeconomy in which value can be extracted at various stages of food production. Every part of the process, including farmyard manure, offers the possibility of an income stream.
'This multifunctional land use includes farm land with biodiversity and climate benefits, but we need private and green finance to fund the transition,' said Prof Mark Scott, of University College Dublin's School of Architecture, Planning and Environmental Policy.
Prof Scott, who chaired the technical group for the review, says change is needed at scale because current land use will undermine both biodiversity and the economy.
Phase two will inform the Government's climate-action plans to achieve emissions reductions in the areas of land use, land-use change and forestry. This is in the context of potential EU fines for overshooting our agricultural emission targets. There is also a need for climate adaptation to protect our rural landscapes from the effects of climate change.
Prof Scott added that as so much land is owned by farmers, rural communities must be central to managing change in the long term. 'We need to give farmers certainty about how they use their own land,' he said. 'Deciding about land-use goals should be a social process rather than a top down technological process.'
At the festival, Dr David Styles, associate professor in agri-sustainability at the University of Galway, presented a number of future scenarios. They included maximising livestock protein within environmental constraints (i.e. specialising in dairy with significantly less beef farming) and a focus on cattle and nature through extensive rather than intensive grazing.
Ireland is way behind on its forestry-planting targets
He also emphasised a focus on pigs, poultry and protein crops (all of which have lower emissions than cattle farming), with grass in clover to reduce fertiliser input and a bioeconomy focus with plant protein, willow and energy.
'We have a very productive land bank but if we used less land for animals and animal feed, we could bring down phosphates and ammonia levels,' said Dr Styles. 'We could produce more protein with half the land, so business as usual isn't necessarily the way forward for food security. Business as usual is very negative with a 2050 lens.'
Dr Styles suggests a well-designed bioeconomy could deliver well for both the Irish economy and environment.
'In the fourth scenario, farmers could grow protein crops (peas and beans) and grass for biorefineries, which produces high-value animal feed as a replacement for imported soyabean,' he says. 'They could also grow willow on marginal land as a feedstock for bioenergy plants producing energy, which could compensate for residual agricultural emissions.'
He talks up the importance of farmers engaging in honest and open conversations about future land-use policy. 'Farmers could be more prosperous. We need to know what fits together for resilience in an uncertain future.'
Dr Styles also suggests that 16,000 hectares of forestry be planted annually from 2030 onwards. Currently, about 2,000 hectares is planted annually, which is about one-quarter of the current target.
Paul O'Brien is a sheep and tillage farmer in Co Kilkenny as well as South Leinster regional chairman of the Irish Farmers Association. He is concerned about the expectations being placed on farmers.
'We are asked to reduce greenhouse gas emissions, increase biodiversity, change our land use and participate in wind and solar energy production, but where is the funding going to come from for all this?' he says.
Mr O'Brien stresses the need to compensate farmers in the event of new policies failing. In this context, he mentioned ash dieback disease, which damaged the majority of ash trees planted by farmers in recent years.
Dr Andrew Kelly from EnvEcon environmental consultancy firm suggests Ireland needs to engage strongly if the European Commission decides to develop an emissions trading system for agriculture. Such a development would, in essence, be the equivalent to a carbon tax on agriculture emissions.
'The emissions trading scheme for energy companies has generated investment in renewables,' he said. 'There are different types of farms and levels of profitability and some farmers won't be viable in the future, just like some businesses fail.'
Prof Yvonne Buckley of Trinity College, co-chair of the All-Island Climate and Biodiversity Research Network, said at the event: 'To be agile in the future and to make money from land, we need diverse landscapes. Healthy ecosystems are at the heart of this. We need to protect the ones we have and restore degraded ones.'

Dr James Moran, lecturer in ecology and biology at Atlantic Technological University in Galway, believes 30-year planning for land use is essential. 'We need to start working together on future policy and we need to consider the interlinked challenges of biodiversity, water quality, food and health of humans and animals,' he said.
Dr Moran acknowledges that in more recent years, the Common Agricultural Policy (CAP) has moved from a food-first approach to one that 'protects nature and water in a liveable climate'.
He said: 'All other EU policies on climate, nature, soil, water need to be integrated into CAP now and we have to transform our land system. Business-as-usual is not an option and a national land-use framework will need to be implemented at regional and local level.'
Niamh Garvey, senior policy analyst with the National Economic and Social Council, says scaling up would give more farmers a sense of what future land use might look like. He also points to the importance of lengthening many of the European Innovation Partnerships and EU Life Programme projects that have proved inspirational.
Patrick Barrett, agricultural inspector at the Department of Agriculture, suggests that the biotechnology and food sectors could eventually come together.
He said: 'The Government will need to support investment in cluster-type developments where one company's waste is another's feedstock and the agrifood sector will be part of this, supplying feedstocks and energy to anaerobic digesters and biorefineries.
'For farmers, foresters, fishers to get more value from what they produce, this sidestream of products needs to be unlocked. This is as much a cultural journey as anything else.'

Privatisation of AIB
Sir, – The privatisation of AIB has been greeted in many quarters as a celebration. In fact, it should be regarded as history repeating itself as a potential tragedy. It is welcome AIB management admits its 'profound regrets the bank had to be rescued by the State' and admits that 'it owes a great debt of gratitude to the taxpayer' for the vast support given to the then largest indigenous private sector firm in Ireland. Diarmaid Ferriter reminds us that 'The Irish banking management culture was reprehensible in relation to customer charges, interest rates, facilitation of tax evasion and calamitous risk taking.' (' How can we stop corporate gombeen men running amok again? Credit unions could be the answer ,' June 20th). Banking is similar to a utility like water, the roads, electricity and gas lines. Banking is too important to hand back a dominant company to a small group of self-interested, self-supporting private individuals. READ MORE SMEs and individuals will suffer. History will repeat itself. – Yours, etc, PAUL SWEENEY, Milltown, Dublin 6.

The Irish Times view on planning in Ireland: vital clarity must be restored
An Coimisiún Pleanála was quietly ushered into existence last week. The Minster for Housing, James Browne, formally established the body which has taken of the role of An Bord Pleanála, the previous appeals body for planning applications. It had lost the confidence of the public and the previous government amidst serious governance failures and lengthy planning delays. The establishment of the new commission comes as a worrying sense of drift envelopes this Government's efforts to address the seemingly intractable shortage of housing. The lengthy gestation of the new body is in itself evidence of a seeming lack of urgency. The Planning and Development Bill which created it was was first brought before the Dáil in November 2023, but was only passed by the Oireachtas last October. That was an inexcusably long time, even allowing for committee debate. It took another six months for the minster to commence the section relating to the planning commission. Many other measures remain to be commenced. The costs of such delay are clear for all to see. The latest figures from the Central Statistics Office - published last Friday - show that residential construction activity is falling. READ MORE Paul Reid, a former head of both Fingal County Council and the Health Service Executive has been appointed chairman of the governing body of the new commission. He would seem well qualified to meet the challenges of leading the new body. The biggest is restoring public, political and industry confidence in the speed and clarity of the planning process which rightly carries much of the blame for the housing shortage. The new statutory targets that have now been set for decisions on planning cases including critical infrastructure projects for transport, water, grid and energy as well large-scale residential developments , need to be met. For that to happen the new body will have to get the resources it needs when it needs them. If it doesn't, then the new commission risks being seen as little more than old wine in a new bottle.

Curragh boss says marathon World Pool programmes not a problem for racegoers
Next Sunday's €1.25 million Dubai Duty Free Irish Derby will be the centrepiece of another bumper nine-race card and Curragh officials insist such marathon programmes are not an issue for racegoers. Last year, Irish racing's HQ hosted the first nine-race meeting in modern times to facilitate the lucrative Tote World Pool betting. The Curragh first hosted the pool run by the Hong Kong Jockey Club in 2023 , when it prompted the Derby date to be switched to Sunday for the first time in 14 years. Almost €30 million in global betting turnover was generated on the Curragh action in 2023. Sunday's action could end up being worth up to €700,000 for the Tote here, as well as the Curragh and Horse Racing Ireland . READ MORE Last month's Guineas festival at the Curragh was part of the pool for the first time and also saw a nine-race programme for 2,000 Guineas day. It prompted some complaints about the length of the card, while there was also disquiet at Epsom earlier this month when Derby day there was included on the World Pool and led to an eight-race card. The pool is the biggest co-mingled market in world racing and operated at Royal Ascot last week. The Irish Champions Festival in September is also included in it. The Curragh's Derby festival kicks off on Friday and once more, a €100,000 handicap has been added to Sunday to make it nine races. Brian Kavanagh, chief executive of the Curragh, said he wasn't aware of criticism relating to the length of the programme at last year's Derby or at last month's 2,000 Guineas. 'I think the big days are days when people are here for a day out,' he said on Sunday. 'We've had days when, at the finish, people are looking for more races. 'It has worked fine. It's a chance to put on a €100,000 handicap as an extra race for three-year-olds, which was run for the first time on Derby day last year. Hopefully it will generate plenty of interest and activity." Part of the commentary at Epsom last month revolved around a lack of quality in some of the contests that backed up the big race. Kavanagh said that won't be the case this coming Sunday. Horse Racing Ireland put the fixture list together; that's not just our call — Brian Kavanagh 'These are all premier handicaps, very competitive races, backed up by a number of Listed races and obviously the Derby, the feature race itself,' said the Curragh boss. 'I think people come for the day and whether they stay for all the races or some races is a matter for themselves. It's a good opportunity to put another high-value race and Hong Kong, the World Pool, will take nine races if we put them on. That's the logic to it.' Ticket pricing for the Irish Derby has also come under the spotlight in recent years, nominated sometimes as a contributory factor to underwhelming attendance figures for Ireland's premier classic. An official figure of 11,418 was returned for Derby day last year. The capacity in the grandstand alone is 13,000. Kavanagh pointed out that the entry cost for Sunday's action is €35, providing people buy their tickets online up to Friday. He says this is 'very good value'. After the Friday cut-off, tickets increase to €45. He also confirmed that officials will look at reducing next year's Guineas festival to two days and losing the Friday evening card. However, a similar move in relation to the Derby festival won't be considered. 'Horse Racing Ireland put the fixture list together; that's not just our call. We will look at that (Guineas festival) for next year,' he said. 'But three days is well established for the Derby. The Friday for the Guineas was added just before or just after Covid. The Derby has been three days for more than 20 years, so I doubt that will change.' [ Kevin Prendergast, influential trainer, dies aged 92 Opens in new window ] An unsettled weather outlook for the week ahead could prove an important factor in deciding likely opposition to the Epsom Derby winner Lambourn on Sunday. Aidan O'Brien's star is odds-on in most betting lists ahead of Tuesday's latest acceptance stage where supplementary entries can be made. However, some ease in the going could make the Curragh a possible option for the Epsom runner Lazy Griff. The Dante winner Pride Of Arras failed to act around Epsom and is another potential cross-channel contender.
