| Zusammenfassung |
| For the European Union, the increasing use of renewable energy sources is an
important instrument to reduce its greenhouse gas emissions and to achieve
greater independency from energy imports. Here, agriculture has the chance
to become an important contributor by the cultivation of bio-energy crops.
In this paper, the potential role of irrigated cropland for the cultivation
of silage maize for biogas production is analyzed on the European level. A
methodology is developed to identify suitable locations for maize
cultivation and to evaluate their performance in respect of the amount of
irrigation water and land needed for energy production. For this purpose,
GIS analysis techniques are combined with simulation results from the
process-based vegetation model LPJmL for maize yields and irrigation water
requirements. The generated information can serve as input for the
development of European-scale bio-energy policies and for further analysis
of the water footprint and energy balance of bio-energy systems. |
