Perennial crops in European farming systems and land use change: a model assessment

Ben Fradj, Nosra; Aghajanzadeh-Darzi, Parisa; Jayet, … - International Association of Agricultural Economists - IAAE - 2012

The aim of this paper is to estimate the perennial crop potential regarding new uses like second generation biofuels. We focus on the introduction of a perennial yearly harvested crop, namely the miscanthus, in European agricultural short term supply model - AROPAj. Inserting this crop in the...

Managing water as a Scare Resource in Beef Feedlots

Pluske, Johanna M.; Schlink, A.C. - In: Australasian Agribusiness Review 15 (2007)

Using a bio-economic model, H2OBeef, that includes traditionally considered parameters associated with running a beef feedlot but also incorporates aspects associated with water, changes that can alter water consumption and or price are examined. The results indicate that when water does not...

Theory and Application of Positive Mathematical Programming in Agriculture and the Environment

Mérel, Pierre; Howitt, Richard - In: Annual Review of Resource Economics 6 (2014) 1, pp. 451-470

This review critically looks at the theoretical and empirical foundations of positive mathematical programming and its evolution in the past decade or so. We show how the need to model new empirical phenomena has induced the literature to rethink model specifications and to address new questions...

Economic Impacts of Total Water Use Control in the Heihe River Basin in Northwestern China—An Integrated CGE-BEM Modeling Approach

Li, Na; Wang, Xiaojun; Shi, Minjun; Yang, Hong - In: Sustainability 7 (2015) 3, pp. 3460-3478

This paper develops an integrated modeling approach combined with a top-down dynamic computable general equilibrium (CGE) model and a bottom-up bio-economic model (BEM) to study the economic impact of a total water use control policy in the Heihe river basin, northwestern China. The integrated...
