Environmenatal climatology - ecophysiology interactions

The research objective is an analysis of the environmental interactions of typical existing and potential agroforestry and to develop a model to optimise tree density and tree-crop interactions. Comprehensive ecophysiological measurements in combination with soil and hydrologic parameters will be set up along the environmental gradients from the tree stem to open areas.  The integrated analysis will enable the determination of the spatial pattern crop stress index and growth along with a spatial mapping of tree and crop size.Interactions between the individual components may affect the others and a compromise must be reached largely within three areas: light, water and nutrient. Shade cast by the tree component will be assessed using both standard and innovative methodologies. The heat, energy and water balances are crucial to crop production where an optimal balance of production between trees and crops should be achieved. Thus the facilitation effects between crops and trees as well as counteracting competition effects are key processes. If these processes are better understood and can be quantified an optimised spatial planting scheme can be derived, which increases the ecosystem service provision in an ecologically and economically sustainable manner.
