Bioenergy versus Processing: What is possible from an ethical point of view?
Agricultural production and public perception More than 90% of the German population have no personal relation to agriculture. Their conception of agriculture is – to a large extent – determined by aesthetic impressions and intermittent perceptions, often based on the negative example of crises (e.g. BSE, „rotten meat“, pollution of the environment). Knowledge about agriculture […]

Economic und ecological aspects of bio-energy production
Summary Bio-energy is used in Europe mainly as a result of government policies. Justifications for government intervention are the reduction of CO2 emissions and dependency on energy imports. Surplus agricultural production for many years favoured the governmental promotion of bio-energy. Recent supply shortage for agricultural products calls for a critical review of past policies of […]

Estimation, effectiveness and opportunities of long term genetic improvement in animals and maize
Introduction Genetic improvement in animals and plants for food consumption has been practised and realised since domestication. Intensive improvement, increasingly with incorporation of genetic principles, has been undertaken for a century or more. Much of this has been highly intensive and effective, notably in poultry. There are consequently concerns that genetic variation is being exhausted […]

Global Potential for Energy Recovery from Renewable Resources
Crop based bio-energy can be an important and increasing factor for the energy supply, if the agricultural sector is able to provide mass-produced energy crops. One relevant factor presently limiting the development of bio-energy systems based on energy crops is the availability of land for biomass production. Land availability for energy crop production depends on […]
