Sustainable provision of woody biomass for energy production in agroforestry systems
We investigate alley-cropping systems which combine the production of woody biomass as energy feedstock with conventional field crops in Germany. The aim is an ecological assessment of this novel land-use type.
Agroforestry describes the simultaneous production of trees and crops on one field. That means a spatial combination of forestry and agricultural elements. The aim is to achieve economic and / or ecological additional value by using synergy between trees and crops. A modern form of agroforestry systems are strips of fast growing trees like poplar and willow on agricultural area. The implementation of short rotation coppice (SRC) strips on cropland as agroforestry systems may result in positive effects for close-by crops as well as for the environment. Essential for optimal success is a thoughtful planning of the structure.
The aim of our project is to investigate whether, depending on the conditions of the respective fields, SRC strips can be used to generate wind shelter or reduce water erosion, whether the SRC strips facilitate soil regeneration and carbon storage and whether flora and fauna take advantage from the low-input and structurally diverse agroforestry system.
Within workpackage 3.2, we are studying the significance of poplar strips for the conservation and promotion of functional aspects of biodiversity within the agroforestry system.
