|Title:||Stochastic Dynamic Optimisation: An Analysis of Surface Grading of Peat Soils in Northern Norway||Contributor(s):||Lien, Gudbrand (author); Hegrenes, Agnar (author); Hardaker, John Brian (author)||Publication Date:||2003||Handle Link:||https://hdl.handle.net/1959.11/6618||Abstract:||Farmers in northern Norway have experienced severe winter damage on grassland rather frequently, especially on flat areas and peat soils in regions with an unstable winter climate around zero degrees Celsius. Traditional drainage with drainpipes is normally not sufficient to prevent such damage in these areas. During the past two decades the use of open ditches and surface grading has become the main method of reclaiming and draining peat land. A new heuristic stochastic dynamic analysis method for problems like this, combining simulation and optimisation, is used to explore the profitability of surface grading of peat soils. This analysis indicates that the year in which a ley should be reseeded depends on stage in the growth curve when eventually the winter damage happens as well as on the severity of the damage. Given the present acreage subsidy payment, surface grading is normally profitable from a farmer's point of view.||Publication Type:||Conference Publication||Conference Name:||NJF Seminar No. 345, Oslo, Norway, 2nd - 4th October, 2002||Conference Details:||NJF Seminar No. 345, Oslo, Norway, 2nd - 4th October, 2002||Source of Publication:||Farm Management: Proceedings of NJF Seminar No. 345, p. 137-154||Publisher:||Norwegian Agricultural Economics Research Institute||Place of Publication:||Oslo, Norway||Field of Research (FOR):||140201 Agricultural Economics||Peer Reviewed:||Yes||HERDC Category Description:||E1 Refereed Scholarly Conference Publication||Other Links:||http://www.nilf.no/Publikasjoner/Rapporter/En/2003/R200302Contents.shtml||Series Name:||NILF Report||Series Number :||2003-2||Statistics to Oct 2018:||Visitors: 164
