N-2007 Agriculture, Development, and Nitrogen A problem of too little or too much

The last 40 years have seen an extraordinary change in the global nitrogen cycle. As recently as the 1960s, nitrogen availability on Earth was controlled by natural processes, but the human creation of synthetic nitrogen fertilizer and the release of nitrogen from fossil-fuel combustion now match the natural rate of formation of reactive nitrogen on the planet’s landscape.
The use of nitrogen is imbalanced, with industrialized countries suffering pollution problems from too much nitrogen and low-income countries having a shortage of nitrogen that constrains food production. The goal of the N2007 Symposium is to address these two challenges in an integrated manner. The meeting will bring together some of the world’s best nitrogen scientists with development experts to build a new agenda towards a sustainable use of nitrogen in our planet.

International Congress on Modelling and Simulation

Land, Water and Environmental Management: Integrated Systems for Sustainability

On 19, 20 and 21 March 2007, Wageningen UR (The Netherlands) and the University of Kiel (Germany) organize the International Conference on Ammonia in Agriculture: Policy, Science, Control and Implementation. It addresses ammonia in agriculture in a broad sense; from the policy on ammonia inventory and abatement in different world regions to measuring methods and mitigation strategies.

The Conference is held in Conference Centre "De Reehorst", Ede, The Netherlands. Hotel accommodation is available at the Conference Centre (approx. 80 rooms) and at the Wageningen International Conference Centre (WICC) in Wageningen (approx. 200 beds).

The issues of concern at the 1st International Workshop on Uncertainty in Greenhouse Gas Inventories, held September 24-25, 2004, in Warsaw, Poland, rooted in the level of confidence with which national emission assessments can be performed, as well as the management of uncertainty and its role in developing informed policy. The 1st Workshop covered state-of-the-art research and developments in accounting, verifying and trading of GHG emissions and provided a multidisciplinary forum for international experts to address the methodological uncertainties underlying these activities. The topics of interest covered national GHG emission inventories, bottom-up versus top-down emission analyses, signal processing and detection, verification and compliance, and emission trading schemes.
