Última Analysis of Environmental and Economic Efficiency: Application of the Overseer model and simulated data AgEcon Ramilan, Thiagarajah; Scrimgeour, Frank G.; Marsh, Dan. New Zealand’s success in raising agricultural productivity has been accompanied by higher input use, leading to adverse effects on the environment. Until recently, analysis of farm performance has tended to ignore such negative externalities. The current emphasis on environmental issues has led dairy farmers to target improvements in both environmental performance and productivity. Therefore measuring the environmental performance of farms and integrating this information into farm productivity calculations should assist informed policy decisions which promote sustainable development. However this is a challenging process since conventional environmental efficiency measures are usually based on simple input and output flows but nitrogen discharge is a...

Ano: 2009 URL: http://purl.umn.edu/97161 Water sharing for the environment and agriculture in the Broken catchment AgEcon Farquharson, Robert J.; Ramilan, Thiagarajah; Stewardson, Michael; Beverly, Craig; Vietz, Geoff; George, Brendan; Dassanyake, K.; Sammonds, M.. The Commonwealth of Australia Water Act 2007 changed the priority for water use in the Murray-Darling Basin (MDB) to first ensure environmentally sustainable levels of extraction and then to maximise net economic returns to the community from water use. The Murray- Darling Basin Authority (MDBA) is expected to deliver a draft Basin Plan in 2011 providing a framework for future water planning. The Plan will include Sustainable Diversion Limits (SDLs) which define water diversions for consumption while maintaining environmental assets and ecosystem functions. The 2009 MDBA Concept Statement acknowledged that in some areas less information is available to determine the SDLs. The 2010 MDBA Guide to the Basin Plan proposed SDLs reducing the current long-term...

Ano: 2011 URL: http://purl.umn.edu/100547 Abatement Cost Heterogeneity and its Impact on Tradable Nitrogen Discharge Permits AgEcon Ramilan, Thiagarajah; Scrimgeour, Frank G.. Nitrogen discharge into the Waikato River has been identified as the primary source of potential water quality degradation. Rising nitrogen levels in water are attributed to non point source pollution from agricultural activities. Pastoral farming is the predominant agricultural land use in the catchment. Increased nitrogen fertilizer use and higher stocking rates have the potential to increase the nitrogen loading into water. There is a range of best management practices and policies proposed to reduce nitrogen discharge from farming systems. Water quality trading is a policy tool that could improve the cost effectiveness of achieving environmental goals. Economic theory suggests that tradable pollution permit systems encourage polluters to reallocate...

Ano: 2006 URL: http://purl.umn.edu/31972 Modelling Waikato Farm Nitrogen Discharges for Policy Analysis AgEcon Ramilan, Thiagarajah; Scrimgeour, Frank G.. This study describes the development of bio economic models examining the economic and water quality impact of various proposed policy options in the Upper Waikato catchment. In the first phase nitrogen emissions are determined for representative farming systems using the Overseer nutrient budget model. These model components are integrated into an economic model, which predicts producer responses to various policy options. The second phase determines catchment wide costs and water quality impacts of riparian buffers by combining geographic information system, bio economic modelling and experimental data. The results of the study signals directions for policy initiatives and further analysis exploring policy design and all costs associated with production...

Nitrogen levels in water resources in the Waikato region are increasing, mainly as a result of non-point source pollution from agricultural activities. Non-point pollution management is a complex issue requiring sufficient information and appropriate institutions. This paper considers the environmental policy literature and analyse how institutions, contract design, and monitoring and transaction costs in the presence of farm heterogeneity encourage optimal abatement. The analysis identifies the key institutional issues to be addressed in the design of appropriate policy measures to address water quality in Waikato river sub-catchment.

Ano: 2007 URL: http://purl.umn.edu/10408 Modelling riparian buffers for water quality enhancement in the Karapiro catchment AgEcon Ramilan, Thiagarajah; Scrimgeour, Frank G.; Marsh, Dan. The use of riparian land buffers is widely promoted as a method of mitigating the effects of sediment and nutrient runoff from intensive land use in New Zealand. Farmers receive advice and financial assistance from Regional Councils for activities such as establishment and planting of riparian buffers, but funding is limited. The effect of buffers on water quality goals varies across land types so the optimum size of riparian buffer width varies across farms. We build a stylised model to determine the optimum buffer width and apply it to the Karapiro catchment. The model can easily be extended to model salinity removal, conservation reserve programmes, establishing wetlands and carbon sequestration.
