In Rhineland-Palatinate (Germany), a high percentage of the forest area is located on poor soils with low buffering capacity. Extensive liming applications were performed to compensate for the negative consequences of acid deposition. In 1988, three

Atmospheric deposition of nitrogen (N) has exceeded its demand for plant increment in forest ecosystems in Germany. High N inputs increased plant growth, the internal N cycling within the ecosystem, the retention of N in soil and plant compartments,

This chapter recaps the outcomes of the National Forest Soil Inventory (NFSI) and the Intensive Forest Monitoring studies, discussing their implications for forestry and forest policies. Clean air policies and forest liming show an effect against soi

The optimization of complex adaptive operating systems is certainly a challenge. Such a system exhibits emergent behavior through learning and adaption of the entities it is composed of. We propose the OR control tower concept to address the optimiza

The rapid re-establishment of forests following large disturbances is being seen as one option to increase the contribution of forests to climate change mitigation. The temporary inclusion of pioneer trees as nurse crops on disturbed sites can facili

Space antennas with a helical geometry are an advantageous choice for many applications, for instance if the transmission of electromagnetic waves with a circular polarization is intended, or if signals from terrestrial objects shall be received with

Workforce planning is a critical success factor for every organization and an important field in operations research (OR). In contrast to most existing OR workforce models we explicitly consider the heterogeneity of real world workforce systems by in
