“…Identification of these CSA's can be resource intensive but once indentified potential costs and benefits of a variable buffer can be assessed at a local level . Doody et al (2012) provide a critical overview of CSA identification for policy formulation, especially in catchments with sensitive water bodies. By assessing farmers' willingness to accept compensation to participate in these CSA buffer zone schemes, following the approach discussed in this paper, policy makers would be in a position to target areas with the highest benefit-costs ratios.…”

In the European Union, mitigation measures to abate diffuse pollution from agricultural land are implemented under the direction of the EU Nitrates and Water Framework Directives. As these measures are implemented in national policies, a review process will look at the efficacy of the measures with a view to recommending further measures as necessary and following scientific and stakeholder consultation. Riparian buffer zones, beyond those zones used as mandatory set back distances for fertiliser and organic manure spreading, have been used as filters in some countries to attenuate nutrient rich runoff and may be proposed as supplementary measures elsewhere. Notwithstanding the ongoing research on the physio-chemical efficiency of riparian buffer zones, this study examined the willingness of farmers to adopt such features on agricultural land. The sample size was 247 farmers in 12 catchments (approximately 4-12km 2 ) in the Republic of Ireland. The survey was based on a proposal to install a 10 metre deep riparian buffer zone on a five year scheme and the analysis was based on principal components analysis, contingent valuation methodology and a Generalized Tobit Interval model. Results from this analysis indicated that famers' willingness to supply a riparian buffer zone depended on a mix of economic, attitudinal and farm structural factors. A total of 53% of the sample indicated a negative preference for provision. Principle constraints to adoption include interference with production, nuisance effects and loss of production in small field systems. Of those willing to engage with supply, the mean willingness to accept based cost of provision for a 10 metre riparian buffer zone was estimated to be €1513 ha -1 per annum equivalent to €1.51 per linear metre of riparian area.

“…Controlling nutrient loads from agriculture therefore depend not only on how much the inputs can be reduced, but how those inputs are managed on the farm and how cultivation and cropping practices can be adapted to reduce the mobilization and transport of legacy soil nutrients through runoff and erosion [32,109,110]. Critical source areas and delivery pathways of P transfer on farms are numerous, dynamic and complex, and will clearly differ between landscapes with permeable and impermeable soils, and only their accurate identification will provide a sound basis for the implementation of effective options to mitigate P transport [111][112][113]. End-of-pipe (retention) solutions are arguably not a sustainable method of reducing eutrophication risk [58].…”

Abstract:The eutrophication of surface waters has become an endemic global problem. Nutrient loadings from agriculture are a major driver, but it remains very unclear what level of on-farm controls are necessary or can be justified to achieve water quality improvements. In this review article, we use the UK as an example of societies' multiple stressors on water quality to explore the uncertainties and challenges in achieving a sustainable balance between useable water resources, diverse aquatic ecosystems and a viable agriculture. Our analysis shows that nutrient loss from agriculture is a challenging issue if farm productivity and profitability is to be maintained and increased. Legacy stores of nitrogen (N) and phosphorus (P) in catchments may be sufficient to sustain algal blooms and murky waters for decades to come and more innovation is needed to drawdown and recover these nutrients. Agriculture's impact on eutrophication risk may also be overestimated in many catchments, and more accurate accounting of sources, their bioavailabilities and lag times is needed to direct proportioned mitigation efforts more effectively. Best practice farms may still be leaky and incompatible with good water quality in high-risk areas requiring some prioritization of society goals. All sectors of society must clearly use N and P more efficiently to develop long-term sustainable solutions to this complex issue and nutrient reduction strategies should take account of the whole catchment-to-coast continuum. However, the right balance of local interventions OPEN ACCESS Sustainability 2014, 6 5854 (including additional biophysical controls) will need to be highly site specific and better informed by research that unravels the linkages between sustainable farming practices, patterns of nutrient delivery, biological response and recovery trajectories in different types of waterbodies.

“…For good water quality in Irish water bodies, it is considered that P additions from all sources should not give rise to a concentration > 0.035mg l −1 (Bowman 2009). To date, arable land in Ireland has received limited attention for its potential to impact on water quality (Doody et al 2012).…”
