The potential of Paulownia tomentosa in agroforestry systems – a literature review.
P. tomentosa (princess tree, empress tree, Kiri-Baum, Blauglockenbaum) is a deciduous hardwood tree native to central and western China. It is fast-growing, has importance in Traditional Chinese Medicine, and may possess some potential for cultivation as bioenergy crop or inclusion in agroforestry systems in the Rhine-Waal region in the context of climate change adaptation. The purpose of this thesis is to compile and evaluate the existing literature on this tree species use a systematic literature review approach.

Caveats and Opportunities of Planting Urban Trees: Predictors for Effective Communication
Which are the factors that influence whether a public communication campaign for planting urban trees is effective? Which environmental and economic, social and cultural aspects of such initiatives foster or hinder their public acceptability? Which caveats and concerns, hopes and expectations do citizens express when confronted with plans for urban trees to be planted in their neighbourhood, and which are the communication measures these attitudinal changes correlate with?

Analysing the heat reduction effect of urban trees in Kleve.
Trees in cities can contribute to reducing the Urban Heat Island effect during hot summer days, thereby contributing to reduced energy consumption (for air conditioners) and health problems resulting from heat stress, for example. This thesis aims to experimentally determine the magnitude of this effect for selected urban green spaces in Kleve.

Analysis and recommendation of suitable urban tree species and management strategies under conditions of climate change.
Dry summers, the spread of non-native tree pests and other consequences of global warming put high stress on urban trees. This research, through a review of literature and expert interviews, aims to identify promising approaches for the city of Kleve to make its urban trees future proof, including species selection and tree management strategies.
