BIO-ECONOMIC MODELING OF WATERSHED RESOURCES IN ETHIOPIA
Okumu, B N; Jabbar, Mohammad A.; Colman, D; Russel, N - International Livestock Research Institute (ILRI), … - 1999
This paper examines the theoretical and practical aspects of natural resource use in the poor tropics given limited technological and policy intervention. Results show that if farmers were to reallocate their land use activities based on land suitability, and utilize between 10-20% of their farm...

Reducing the impact of Sclerotinia disease by determining optimum crop rotations using dynamic programming
Vosough Ahmadi, Bouda; Burnett, Fiona J.; Young, Caroline S. - Land Economy and Environment Group, Scotland's Rural College - 2013
Sclerotinia rot is a disease caused by the fungus Sclerotinina sclerotiorum which affects a wide range of crops and causes major yield and economic losses. Crop rotation is an important strategy for minimising losses. A dynamic programming (DP) model was developed to study the trade-offs between...

Die Berücksichtigung von Unsicherheit und Flexibilität in der Investitionsplanung – dargestellt am Beispiel einer Vertragsinvestition für Roggen
Musshoff, Oliver; Hirschauer, Norbert - In: German Journal of Agricultural Economics 53 (2004) 4
Investment decisions are, as a rule, characterized by uncertainty, irreversibility and flexibility. Simple net present value calculations will not account for these features. In many situations even flexible investment planning with decision trees, which represents the most advanced method of...

A Dynamic Optimisation Model of Weed Control
Cacho, Oscar J.; Jones, Randall E. - School of Economics, Business School - 2000
It is argued in this paper that static approaches to weed management, where the benefits and costs are only considered within a single season, are inappropriate for assessing the economic benefits of weed control technologies. There are carryover effects from weed management as weeds that escape...

Optimisation of policy interventions in environmental quota
Buysse, Jeroen; Van der Straeten, Bart; Nolte, Stephan; … - European Association of Agricultural Economists - EAAE - 2010
The paper analyses the governance choices in production quota with the Flemish nutrient production rights as a case. A static model of quota trade in the short run shows the inefficiency of discrete non-auctioned trade with fixed transaction costs. This model also shows that an obligation to...

An analysis of sugarcane harvesting options in the Tully mill area using dynamic and linear programming
Lawes, R.A.; Wegener, Malcolm K. - Australian Agricultural and Resource Economics Society … - 2002
Sugarcane in a perennial crop harvested annually over a six-month season from June to December. Each crop cycle consists of a plant crop followed by several ratoon crops. Time of harvest influences both commercial cane sugar (CCS) content in the current season and yield in the following season....
