Within the framework of the nitrate directive, member states have the possibility to apply forderogation, i.e. increasing fertilization standards under certain conditions. Several EU regionshave made use of this possibility but all in a different way. In 2009, 6 different derogationpolicies were...

The paper discusses an ex ante evaluationof the derogation on the Nitrates Directive for Flanders,Belgium, which is a case of intensive but highlyproductive livestock areas. The aim is to develop anaccurate simulation model to detect small differences inmanure surpluses caused by changes of...

Organic farming and fair trade certified chains have emerged in West-Africa since the 1990s inanswer to new alternative markets in developed countries. These chains, involving actors fromNorth and South, are seen as an opportunity to sustainably valorise the small peasants agriculturein Africa...

A spatial price equilibrium (SPE) model of the world sugar market is programmed. The model coversmore than hundred regions and contains sugar in as a sole product. It has a detailed coverage ofpolicies and bilateral trade agreements. It is programmed as a mixed complementarity problem(MCP) in...

In South Africa water law has recently changed, adopting the principle of water as an economic good,thus levying charges on its use. For small-scale irrigators this is an important change, becausecurrently their water use is entirely subsidized. In the coming years, subsidies will gradually...

This article analyzes the efficiency of Water Users Associations (WUA) in the Cap Bon region(Tunisia) and studies its main determinants. The analysis is performed in two stages. First, theefficiency is measured via the nonparametric “Data Envelopment Analysis” (DEA) technique. TheDEA models...

The paper aims to investigate the economies of scale of Water Users’ Associations (WUA) inTunisia. During the last years there has been a lot of discussion in Tunisia about the optimal sizeof WUAs, which allows more efficient management of the water resources at the local level. Inthis work we...

The paper uses the case of Flemish investment support to make a quantitative analysis of pillarII support based on micro-economic data from the FADN and the administrative dataset of theinvestment support fund. A dynamic panel estimation quantifies the effect of support for settingupyoung...

An agricultural sector model for ex ante policy analysis is developed and applied for the simulation of alternative implementations of the Agenda 2000 Mid Term Review (MTR). The model uses an adapted version of Positive Mathematical Programming allowing simultaneous modelling of individual...

This study estimates the technical, allocative and economic efficiency obtained from the Data Envelopment Analysis (DEA) approach using farm level survey data to a sample of 100 poultry farmers in Bangladesh for the year 2007. The results from the DEA approach show that there is substantial...
