@masterthesis{Gehrmann, type = {Bachelor Thesis}, author = {Gehrmann, Bastian}, title = {The Impact of Planted Green Facades on Biodiversity and Tem perature in the immediate Surroundings of urban Buildings}, school = {Hochschule Rhein-Waal}, abstract = {People and nature are affected by climate change in different ways. The effects of diminishing green spaces, increasing sealed spaces, and higher summer temperatures are particularly noticeable in built-up and urban areas. The constant use of land and development means that insect habitats, which are essential to a functioning ecosystem, are being lost. But this development is not only problematic for insects: increased sealing also increases the potential risk of the heat island effect, which poses a threat to human health. One possible solution for providing habitat and food for insects in urban areas could be green fa{\c{c}}ade systems. These could partially restore ecosystem services lost to development and have a positive effect on ambient temperature through shading of the building and evaporation from the plants. In order to measure this effect of fa{\c{c}}ade greening on the environment, in particular on insect diversity and insect population, this work measured the number of insects using two different counting methods over several days on two external fa{\c{c}}ades, one with fa{\c{c}}ade greening and one without. In addition, to determine the effect of the green fa{\c{c}}ade on the ambient temperature, the temperature was measured at different parts of the fa{\c{c}}ades at both measurement locations. The result of the work is that the fa{\c{c}}ade with plants has a significantly higher insect biodiversity and insect density than the fa{\c{c}}ade without plants. Temperatures are cooler, in most cases, on a green fa{\c{c}}ade. However, they are not particularly significant and show large fluctuations. The paper also outlines a possible way of analysing demand and developing a possible sales concept.}, language = {en} } @masterthesis{Marquardt, type = {Bachelor Thesis}, author = {Marquardt, Johanna}, title = {Biodiversity changes in vegetation and insects following the creation of a wildflower strip: A Case Study}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-7061}, school = {Hochschule Rhein-Waal}, pages = {112}, abstract = {With the Global Climate Change, the loss of biodiversity is one of the most current and biggest crises of today and the future. The loss i.e., the decrease of biodiversity, does not only have negative effects on vegetation and animals, but also on humans. If nature is doing well, people are doing well. In order to counteract the loss, this bachelor thesis attempts to increase plant and insect biodiversity at a specific location with insect-friendly seed mixtures and by measuring the change using comparison areas. Accordingly, the two research questions were addressed: (1) "How does plant-biodiversity change in the backyard and front yard on the seed mixture plot compared to plant-biodiversity in the backyard and front yard next to the seed mixture plot?" and (2) "How does insect-biodiversity change in the backyard and front yard on the seed mixture plot compared to insect-biodiversity in the backyard and front yard next to the seed mixture plot?" To answer these research questions and to obtain more suitable data, a wildflower strip was established in the backyard and one in the front yard, each with an adjacent reference field, to ensure equal environmental conditions and to detect changes in flora and fauna. Plants and insects were observed and documented during the flowering period in order to determine differences in biodiversity sizes afterwards. The comparison of the different biodiversity sizes shows that an increase in insect and plant biodiversity can be achieved by planting insect-friendly wildflower strips. As the increase of plant biodiversity also leads to the increase of insect biodiversity. Further research in the field of biodiversity enhancement could be done by collecting more measurement points of the coefficients at additional locations to extend the data set and to improve the applied method of this bachelor thesis. Also, the recordings could be repeated over a longer time period of several years.}, language = {en} }
