The Potential Cost to New Zealand Dairy Farmers from the Introduction of Nitrate-Based Stocking Rate Restrictions

Neal, Mark; Fulkerson, William; Levy, Gil; Wastney, Meryl; … - International Association of Agricultural Economists - IAAE - 2006

Introducing a stocking rate restriction is one possible course of action for regulators to improve water quality where it is affected by nitrate pollution. To determine the impact of a stocking rate restriction on a range of New Zealand dairy farms, a whole-farm model was optimised with and...

Approximating optimal numerical solutions to bio-economic systems: How useful is simulation-optimization?

Borner, Jan; Higgins, Steven Ian; Scheiter, Simon; … - International Association of Agricultural Economists - IAAE - 2009

approximating “true” optima of complex dynamic optimization problems using a technique called simulation-optimization. We develop a … standard discrete renewable resource use problem and solve it numerically using both simulation-optimization and non … simulation-optimization vis-à-vis non-linear programming in predicting optimal control and state variable paths. On the basis of …

Viability of the Raw Cotton Production in Spain After the Decoupling of the Subsidies

Arriaza Balmón, Manuel; Gomez-Limon, Jose Antonio; … - International Association of Agricultural Economists - IAAE - 2006

Considering the latest reform of the EU's Cotton Regulation of 29th April 2004, which will come into force in the 2006/07 season, we analyse its impact on the cotton production sector of Andalusia. The decoupling of subsidies implies that producers will be entitled to 65 percent of the amount...

Evaluating the Potential of Whole-Farm Insurance Over Crop-Specific Insurance Policies

Bielza, Maria; Garrido, Alberto - International Association of Agricultural Economists - IAAE - 2006

Since 1996, different formats of whole-farm insurance (WFI) have been launched in North America and Spain. Their rationale is to pool all farm's insurable risks into a single policy that provides cheaper coverage against the farm's revenue losses. We evaluate the gains of moving from a situation...

Payments for Environmental Services: A Peruvian Case Study

Rojas Lara, Teresa - International Association of Agricultural Economists - IAAE - 2012

Globally, land use changes and deforestation contribute with around 20% of the green house gases emissions. Payments for Environmental Services (PES) schemes constitute a way to cope with these problems and promote the conservation of natural resources using market-based incentives. Through...

Improvement of a bio-economic mathematical programming model in the case of on-farm source inputs and outputs

Aghajanzadeh-Darzi, Parisa; Jayet, Pierre-Alain; … - International Association of Agricultural Economists - IAAE - 2012

A signicant part of crop productions is not marketed and can be totally (fodders and pastures) or partly (cereals) used on-farm. Regarding inputs, Nitrogen fertilizers are also not only provided by the market, but they are signicantly on-farm provided by livestock. When outputs and inputs are...
