Última REDUCING NITROGEN LOSSES FROM AGRICULTURAL SYSTEMS: AN INTEGRATED ECONOMIC ASSESSMENT AgEcon Hartmann, Michael; Hediger, Werner; Peter, Simon. The loss of reactive nitrogen from agriculture into the environment is a major threat to the global environment and a challenge for agri-environmental policy. We therefore investigate the problem of reducing nitrogen losses from agriculture into the environment from an economic perspective. Based on a recursive-dynamic linear programming model, our study reveals that the above difficulty is primarily due to the rigidities associated with the nutrientforage cycle and existing production structures. Moreover, we assess the cost and effectiveness of different nitrogen taxes for the case of Switzerland. Our results show that a tax on fertilizers only exhibits the best performance in terms of cost-effectiveness.

Ano: 2007 URL: http://purl.umn.edu/7583 Evaluating the efficiency of a N-input tax under different policy scenarios at different scales AgEcon Petsakos, Athanasios; Jayet, Pierre-Alain. Nitrate pollution from agriculture is an important environmental problem, caused by the excessive use of inorganic fertilizers. The internalization of this externality, via a tax on mineral nitrogen, could lead to a second best solution, reducing nitrate emissions. Several authors suggest that a reduction in agricultural support could produce similar results. In this paper we examine the effects of a nitrogen levy on nitrate pollution from agriculture in northern France under two different policy scenarios corresponding to (i) the Agenda 2000 and (ii) the Luxembourg reform of 2003, including the 2006 arrangement. The analysis aims at revealing what synergies or conflicts are created between a fertilizer levy and the policy scenarios, with respect to...
