Última Políticas para estabilizar el mercado de la sandía (Citrullus lanatus) en México. Colegio de Postgraduados García Vázquez, Alejandra. Como consecuencia de la existencia de excesos de oferta, actualmente los productores de sandía (Citrullus lanatus) se enfrentan al problema de disminución de precios en los meses de mayo, junio y julio. Esta situación es recurrente cada año, y repercute de forma negativa sobre los ingresos y ganancias de los productores debido a la inexistencia de un organismo gubernamental que realice la planeación de la producción en el tiempo. Con el objetivo de modelar diferentes medidas de control de la oferta como alternativas para mejorar la ganancia de los productores, se formuló un modelo de programación lineal que incorpora características espaciales e inter-temporales del mercado de la sandía en México para el año promedio 2006-2008. Los resultados indican que... Palavras-chave: Ganancia; Mercado; Modelo de programación lineal; Oferta; Precios; Linear programming model; Market; Prices; Profit Supply; Maestría; Economía.

Ano: 2010 URL: http://hdl.handle.net/10521/93 IMPACTS OF POLICY REFORM ON SUSTAINABILITY OF HILL FARMING IN UK BY MEANS OF BIO-ECONOMIC MODELLING AgEcon Acs, Szvetlana; Hanley, Nick; Dallimer, Martin; Robertson, Philip; Gaston, Kevin J.; Armsworth, Paul R.. Hill farming in UK is experiencing very difficult economic circumstances and many farmers rely on subsidies provided by the government for a large fraction of their income. The Peak District National Park is used as a case study to examine how farmers might respond to current policy changes � in particular, the move from area- and headage-based payments to the Single Farm Payment, and how optimal business plans should respond to these changes. The objective of this paper is thus to develop production models that predict how farmers will respond to changing policy framework conditions. For this purpose socio-economic surveys were carried out on 44 sample farms, in order to investigate how the land is managed on hill farms including ongoing policies and...

Ano: 2008 URL: http://purl.umn.edu/6645 Conflicts over Water in the Upper Klamath Basin and the Potential Role for Market-Based Allocations AgEcon Jaeger, William K.. The curtailment of irrigation on the Klamath Reclamation Project in 2001 is estimated to have cost farmers more than $35 million. This study examines how alternative water allocations among irrigators in the Upper Klamath Basin could have lowered those costs. Per acre marginal water values vary by a factor of 20 due primarily to variations in soil productivity, with the highest productivity lands concentrated in the federal Project. A linear programming model estimates costs for alternative allocations. Findings indicate that compared to the 2001 allocation, costs could be reduced by 75% with a market-based approach.

Ano: 2004 URL: http://purl.umn.edu/31103 Linear programming model to optimize the water resource use in irrigation projects: an application to the Senator Nilo Coelho Project Scientia Agricola Frizzone,J.A.; Coelho,R.D.; Dourado-Neto,D.; Soliani,R.. The main objective of this paper was to develop a separable linear programming model, considering a set of technical factors which may influence the profit of an irrigation project The model presents an objective function that maximizes the net income and specifies the range of water availability. It is assumed that yield functions in response to water application are available for differents crops and describe very well the water-yield relationships. The linear programming model was developed genetically, so that, the rational use of the available water resource could be included in an irrigation project Specific equations were developed and applied in the irrigation project "Senator Nilo Coelho" (SNCP), located in Petrolina - Brazil Based on the...
