Consideration of landscape in the framework documentation during the evolution of the Rural Environment Protection Scheme (REPS) in the Republic of Ireland.Whelan, Jackie; Fry, John; green, stuart; Teagasc Walsh Fellowship Programme (Teagasc, Oak Park, Carlow, Ireland, 2010)This paper looks at the changing concept of landscape during the evolution of REPS. It reviews and groups definitions of landscape and identifies their agri-environmental relevance. Descriptions were devised to amplify each grouping with reference to an Irish context and were used as an analytical framework to categorise each landscape reference in REPS documentation. There was an increase in the use of the term landscape with each version of the scheme and expansion in the range of different landscape categories to which this apparently applied. However there has been no coherence in its use. This paper makes recommendations to improve the framework for the treatment of landscape issues in REPS and its future evolution.
Modelling the Marginal Abatement Cost of Mitigating Nitrogen Loss from Agricultural LandChyzheuskaya, Aksana; O'Donoghue, Cathal; Buckley, Cathal; Ryan, Mary; green, stuart; Gibson, Mark (Teagasc, Oak Park, Carlow, Ireland, 2012)With the deadline identified by the Water Framework Directive (2000/60/EC) approaching in 2015 there is increasing pressure on policymakers to introduce new regulations to achieve water quality targets. Agriculture is one of the contributors of diffuse pollution entering watercourses and will come under pressure to reduce pollutant loads. This paper produces Marginal Abatement Cost (MAC) Curves for eight policy measures that could potentially reduce nitrate leaching from agricultural land on Irish dairy farms. These include: 1) reduction of fertiliser application by 10%; 2) reduction of fertiliser application by 20%; 3) livestock unit reduction to limit organic N to 170 kg ha-1; 4) reduction of livestock units by 20%; 5) change of feed mix to reduce cow dietary N intake; 6) fencing off watercourses to introduce a buffer zone; 7) improved dairy cow genetic merit by introducing higher performing dairy breeds; 8) more efficient slurry application. Results from this study indicate that there will be reductions in farm gross margins across nearly all policy measures. However, MAC and the ranking of MAC vary across individual farms and aggregate MAC does not reflect the heterogeneity of impacts across individual farms. This paper shows that any measure introduced in a “one size fits all command-control” fashion will not yield efficient economic results.
Public access to the countryside: An exploration of the costs and benefits of farmland walking trailsHowley, Peter; Doherty, Edel; Buckley, Cathal; Hynes, Stephen; van Rensburg, Tom M.; green, stuart; Department of Agriculture, Food and the Marine, Ireland (Teagasc, Oak Park, Carlow, Ireland, 2010)To date, estimates of individuals’ willingness to pay (WTP) for access to the countryside have typically been on sites of special interest such as developed walking routes, public rights of way in specific areas, national parks and forests (see Lockwood and Tracy, 1995; Bennett and Tranter, 1997; Crabtree and MacDonald, 1997; Liston-Heyes and Heyes, 1999; Garrod et al., 1998; Bennett et al., 2003; Buckley et al., 2009; Morris et al., 2009). There has been little if any attempt to derive estimates of individuals’ WTP for the provision of walking trails in the wider countryside at a national level. The present study aims to build on previous work by examining the demand for particular types of walking trails through a nationally representative survey of the Irish population. One further advantage of this research is that apart from valuing walking activities in a generic sense this paper investigates what types of investment in facilities associated with walking trails generate the greatest welfare gains. Furthermore, using a nationally representative survey of the farming population this paper examines farmers’ willingness to participate in a hypothetical walking scheme whereby the general public will be allowed access to specific trails. First by way of background this paper will discuss the situation in relation to access rights to the countryside across a number of countries. Second this paper will outline the research approach which is followed with a discussion of the empirical results. Finally this paper will conclude with a discussion of the papers main findings and their implications for the provision of public access to the countryside.
