Última The non-permanence of optimal soil carbon sequestration AgEcon Hediger, Werner. Carbon sequestration in agricultural soils is considered as an option of greenhouse gas mitigation in many countries. But, the economic potential is limited by the dynamic process of saturation and the opportunity cost of land use change. In addition, this article shows that permanence cannot, in general, be achieved in the strict sense of maintaining the soil carbon stock on an increased equilibrium level. Rather, a cyclical pattern with periodical release of sequestered carbon can be economically optimal from both the farmers’ and societal point of view.

We investigate the question whether the concept of corporate social responsibility (CSR) could be used to replace or complement those of multifunctionality and sustainability in the agri-food sector. It shows that the double role of citizens as tax payers and customers requests and allows us to directly link the problems of governance and stakeholder society in an intertemporal framework of total value maximisation and sustainable development. Thus, the concept of CSR provides a link between the views on agriculture’s multifunctionality and sustainability. Moreover, the fact that some actors in a vertical market, such as the agri-food chain, can exercise market power and absorb tax money and resource rents enforces the need of a broader perspective which...

Ano: 2008 URL: http://purl.umn.edu/36854 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.
