This thesis investigates whether freely available, coarse-resolution, Passive Microwave Remote Sensing (PMRS) data (37 GHz) can be effectively used for early warning systems for floods in Malawi. The Shire River Basin in Chikwawa and the smaller-scale North Rukuru River Basin in Karonga were studied using two alternative, ratio-based satellite indices that make use of the signal difference between
Cycling has been identified as a central element of the solutions to some of the most pressing challenges for today’s cities, such as poor air quality, rising CO2-levels due to emissions from motorised traffic, traffic congestions, and sedentary lifestyles. A high-quality, safe, and widespread network of cycling infrastructure is a key part in the quest to encourage more people to choose the bicyc
Saltmarshes are areas of coastal grassland that are regularly flooded by seawater. They support a large number of resident and migratory bird species, both overwintering and breeding. The Mersey Estuary Site of Special Scientific Interest (SSSI) is situated in North West England and it supports nationally significant numbers of overwintering wildfowl and waders. Decline of three overwintering bird
This thesis investigated the phenomenon of pupils’ transportation in Abu Dhabi and studied the relationship between their transportation, stress levels, and school performance. This study combined standard and geospatial statistical tools with a quantitative survey of 982 grade 6 to grade 9 students from 40 classrooms of 17 public and private schools in Abu Dhabi Island. The thesis tested five hyp
European rivers experience increasing concentrations of total organic carbon (TOC) from terrestrial sources due to factors involving changes in land use, climate and soil acidity. However, low interest is given to the evolution of total organic nitrogen (TON) concentrations in surface waters, the links with TOC concentrations and the influence of the surrounding land cover on nutrient inputs. Inve
The urge for more sustainable and environmental-friendly transportation has never been as high as it is today. The demand will probably continue to increase as the knowledge about climate change continues to widen and as the expectations, of mitigation and adaptation measures, intensifies. One sector that is in great need of taking more mitigation and adaptation measures is the transport sector. T
Evaluating suppliers is something that the majority of companies has to do and is something that often is a complex problem with many parameters and variables involved. This is especially true for a company like Kiviks Musteri that purchases a variety of different products from all over the world from different types of suppliers that come from different cultures and backgrounds. It is also essent
Community based approaches to conservation in the developing world have generally been criticized for not meeting their goals of sustainable conservation and local development. Inadequate local participation and inequitable benefits sharing among others are some of the major concerns. In Tanzania wildlife management areas (WMAs) are one of the forms of community-based wildlife conservation initiat
Informal green spaces are “small green areas” which are some square meter plots along streets or in junctions, in front of public or private buildings. Informal urban green space become or remain in neglected condition due to the lack of capacity of the municipality to maintain them. Further, there is a lack of responsibility, competency and motivation of the residents to voluntarily take care of
Anthropogenic land-use covers a constantly increasing fraction of the terrestrial surface area. By employing a dynamic global vegetation model, human-induced changes in the terrestrial water balance as compared to an undisturbed scenario were simulated. The results suggest that humanity is a main driver of change in the terrestrial water balance in general and green water in particular. Most strik
Industry Foundation Classes (IFC) models from the Architecture, Engineering and Construction (AEC) -industries can contain information on building life-cycle entities. Urban planning and related domains are interested in data conversions between IFC and City Geography Markup Language (CityGML) because of this. However, the maintenance and versioning of CityGML life-cycle building data poses a s
The summer of 2017 was climatically close to normal in southern Sweden, whereas the following summer was unusually warm and dry. These two years therefore make an interesting case study for investigating the impact of severe drought on vegetation, particularly when considering that climate change is predicted to lead to an increased frequency of drought events in the study area. The comparison wa
Reducing inequality is number 10 of the United Nations sustainable development goals. Inequality in society affect economic growth, development and poverty reduction, and through these indirectly affect environmental degradation, food security and other major problems facing society today. Analyzing the temporal and spatial dynamics of economic inequality requires comparable data on finer scales.
Climate change and human impact play a huge role in the sustainability and development of ecosystems and the services they offer to societies over temporal and spatial scales. Fossil pollen-based estimates provide unique information on past land cover change, but to date there are not many methods able to create spatially continuous maps and have a fine scale of land cover changes inferred from po
Nitrogen dioxide (NO2) is an important air pollutant with both environmental and epidemiological effects. The main aim of this thesis is to explore spatial patterns and temporal trends of tropospheric NO2 concentrations globally using data from the OMI instrument aboard NASA’s Aura spacecraft. Additional aims are to validate the satellite data by comparing it to ground-based measurements, and to f
Fallow, understood as a period where no crop is cultivated during a growing season, is an important crop management practice. Fallow plays an important role in pest and disease management, and monitoring the presence and duration of fallow can have implications for understanding the extent and effectiveness of this agricultural practice. Therefore, fallow period mapping using remotely sensed data
Remote sensing image classification is used in land cover, forest type and tree species classifications but rarely considered for habitat suitability modelling of animal and plant species. It is instead common that land cover products derived from remote sensing data are used in these modelling problems, even though satellite imagery can provide more detailed information. The aim of this project w
During the last few decades, satellite remote sensing has proven to be an important non-invasive method for archaeological research in order to detect ancient sites and manage existing ones. Archaeologists have tried in the recent past to embed Geographic Information Systems (GIS) and image processing techniques in their research as non-destructive approaches, which can allow a wider perception o
Scientific summary: Ground settlement due to groundwater drainage during construction is important to be considered since ground settlement may cause severe building damages. The calculation of ground settlement contained several parameters with different magnitude of uncertainties. Thus a risk evaluation of ground settlement is necessary. The aim of this thesis was first to build a soil strata mo
