Aufbauend auf einer vorherigen Arbeit, die sich mit der Implementierung einer Komponentezum Auslesen mdizinischer Sensordaten mithilfe eines Arduino und eines Raspberry Pi befasst hat, beschäftigt sich diese Arbeit mit der Visualisierung sowie Auswertung der durch das System gesammelten Daten. Das Ziel dieser Arbeit ist es, über einen Zeitraum von etwa drei Monaten mithilfe der Komponente Daten zu sammeln und diese Daten in einem sinnvollen Kontext visuell darzustellen. Zudem sollen diese Daten mithilfe unterschiedlicher Algorithmen des Maschinellen Lernens ausgewertet werden,
um mögliche Muster und Zusammenhänge erkennen zu können. In diesem Kontext konnte die Hypothese aufgestellt werden, dass ein Zusammenhang zwischen der Körpertemperatur und der Sauerstoffsättigung im Blut besteht.
Wetlands offer different ecosystem services that contribute to human well-being (Kovács et al., 2015). According to the Ramsar Convention Secretariat (2018) wetland located in urban areas have been threatened by several activities such as drainage, pollution, encroachment, agriculture, among others. On the other hand, wetland degradation reduces the resilience of hazards like floods and storm surges (Kumar et al., 2017). For that reason, ecosystem-based disaster risk reduction (Eco-DRR) is an important strategy which enhances the conservation and restoration of ecosystems to reduce disaster risk aiming to sustainable development and resilience (Estrella & Saalismaa, 2013). Despite international recognition of the importance of wetlands, urban wetlands have diminished their capacity to cope with flood threats (Boyer and Polasky, 2006) due to the aforementioned human impacts.
That is why this thesis aimed to identify the role of urban wetlands in Bogota, Colombia, that has an urban wetland complex that is recognised as a Ramsar site in 2018. However, wetlands in the city reduced its area from 50.000 hectares to less than 800, approximately, in less than 40 years, mainly because of urban expansion and encroachment (IDIGER, 2018). To achieve this objective, an analysis of the city’s risk management framework was conducted, as well as a stakeholder analysis based on semi-structured interviews and a spatial-temporal analysis for the period 1998-2017, for which the Jaboque wetland was used as a case study. This wetland is located near the Bogotá River and is in the area threatened by flooding.
It was possible to determine that national and district policies on wetlands, biodiversity, and climate change adaptation address some ecosystem functions. Still, disaster risk reduction is not strongly linked to them. Thus, based on the case study, the wetlands in Bogota have not played a decisive role in flood risk management in the city.
