Report from a conference at the Royal Swedish Academy of Agriculture and Forestry April 12th 1999
Nitrogen efficiency in practical agriculture is a topic of extreme importance, particularly with regard to identification of where the real problems are to be found.
The theme of today’s discussion is how efficiently one can use nitrogen that is present in the soil, nitrogen that is built into the soil, and nitrogen provided through the addition of manure, organic matter or fertilisers. Of key interest are global changes and changes in the composition of the atmosphere. Additionally, we may touch upon the research that is ongoing in Sweden into wetlands and the establishment of wetlands as nitrogen sinks, primarily with the aim of getting the nitrogen into the air rather than into the waterways, together with the removal of N-rich residues and careful irrigation.

This report of the Bertebos Conference 2010 outlines challenges and long-term outlooks for food security and the futures of farms. Speakers from China, Ethiopia, India, Brazil and Russia give their views on how small and large scale agriculture are developing in their countries and continents. Trends and possible scenarios for the future are presented. Certain threats will be overcome – others require urgent action.
Arbetsgruppen har arbetat utifrån dagens polariserade skogsdebatt, som inte bara grundar sig på skogsbrukets faktiska konsekvenser för biologisk mångfald och klimat utan också på allmänhetens negativa upplevelser av dagens skogsbruksmetoder. Framför allt tycker man inte om hyggen. Gruppens arbete har resulterat i drygt trettio idéer som skulle kunna minska spänningarna i samtalet kring den brukade skogen.
