Discarded fish in European waters: general patterns and contrasts ArchiMer
Uhlmann, Sebastian S.; Van Helmond, Aloysius T. M.; Stefansdottir, Elisabet Kemp; Siguroardottir, Sigriour; Haralabous, John; Maria Bellido, Jose; Carbonell, A.; Catchpole, Tom; Damalas, Dimitrios; Fauconnet, Laurence; Feekings, Jordan; Garcia, Teresa; Madsen, Niels; Mallold, Sandra; Margeirsson, Sveinn; Palialexis, Andreas; Readdy, Lisa; Valeiras, Julio; Vassilopoulou, Vassiliki; Rochet, Marie-joelle.
To reduce the practice of discarding commercially fished organisms, several measures such as a discard ban and extra allowances on top of landings quotas (“catch quota”) have been proposed by the European Commission. However, for their development and successful implementation, an understanding of discard patterns on a European scale is needed. In this study, we present an inter-national synthesis of discard data collected on board commercial, towed-gear equipped vessels operating under six different national flags spanning from the Baltic to the Mediterranean Seas mainly between 2003 and 2008. We considered discarded species of commercial value such as Atlantic cod (Gadus morhua), haddock (Melanogrammus aeglefinus), European hake (Merluccius merluccius),...

En driftsøkonomisk analyse af økologisk jordbrug - med fokus på teknologi og regelændringer Organic Eprints
Madsen, Niels.
Ny teknologi vil reducere omk. på bedrifter med specialafgrøder, men ikke på bedrifter der har trad. afgrøder. Et skift til 100 pct. økologisk foder, halm og husdyrgødning vil være en fordel for kvægproducenter og en ulempe for planteavlere.

Forbud mod konventionel gylle og foder vil fordyre økologisk planteavl Organic Eprints
Madsen, Niels; Jacobsen, Brian.
Udvikling i økologisk produktion hænger sammen med de fremtidige udviklingsmuligheder. I det gennemførte projekt er de økonomiske konsekvenser af skærpede økologiregler og ny teknologi i økologisk jordbrug beskrevet. Gennem dialog mellem forskere og rådgivere er der først udarbejdet en teknisk og biologisk beskrivelse af 8 økologiske case-bedrifter, hvoraf 4 er planteavlsbrug, 3 er mælkeproducenter og en er svineproducent (Nielsen et al., 2003). Ved valg af sædskifte og arealomfang er det søgt at beskrive fremtidens økologibedrifter. I analyserne opgøres ændringerne i forbruget af arbejdskraft og maskiner samt omkostninger og indtægter. De mest interessante innovative teknologier i en økologisk sammenhæng er blevet udvalgt. Teknologierne omfatter...

Impact of new technologies and changes in legislation on the income on organic farming Organic Eprints
Madsen, Niels; Jacobsen, Brian.
In this project the economic consequences of legislative changes and new technology in organic farming has been examined. Through an interactive process between research experts and agricultural advisors is a technical and biological description of 8 organic case-farms encountering 4 arable, 3 dairy and a single pig farm envisioned (Nielsen et al., 2003). The crop rotation and the production structure of the case farms were chosen as to depict the organic farms of the near future. In order to analyse the consequences on labour input, machinery input and operational cost, case studies have been chosen as the overall methodology. Scenario planning is used as the method of combining factual data and expert evidence to create imaginable and credible scenarios...

Organic farming at the farm level - Scenarioes for the future development Organic Eprints
Jacobsen, Brian H.; Madsen, Niels; Ørum, Jens Erik.
The purpose of this report is to present possible impacts of new technology and changes in legislation on the profitability of different types of organic farms. The aim is also to look at both the current and future trends in the organic area in Denmark. Besides the economic aspects, the report also shows the nutrient surplus for selected organic farms. Analyses carried out at the Food and Resource Economic Institute (FOI) have previ-ously shown that price premiums of up to 50% on pig meat and 20% on arable farm products is needed to make the organic production profitable. The price premium on cereals and dairy products have in the 1990’ties been higher than required, but in re-cent years the price premium has dropped, leading to low profitability,...
