Sensing Soil Properties in the Upper Ewaso Ng'iro Basin by means of Reflectance Spectroscopy and GIS
Hett, Conny
Master's Thesis, University of Bern, Switzerland This thesis is a proof of method study of the Soil Sensing Approach, a new approach for rapid assessment of soil properties using near-infrared spectroscopy. The study was carried out in a small tests area of ten by ten km in the Upper Ewaso Ng’iro Basin, Kenya. The topical aim was to assess soil chemical properties in relation to land cover/land use. Through application of chemometric models soil carbon and nitrogen were predicted based on their near-infrared reflectance curves. CART classification and regression trees were used for modelling the two properties. It was shown that classification trees did not perform nearly as good on the samples as the regression trees. Finally relationships between land cover/land use and soil carbon and nitrogen were assessed and soil carbon and nitrogen showed very similar results. The good results of the Soil Sensing Approach make its use possible for mapping soil carbon and nitrogen properties using satellite imagery. Download
The Challenge of Applying Geographic Information Systems to Sustainable Mountain Development
Heinimann, Andreas
"In recent years, Geographic Information Systems (GIS) have increasingly been used in a wide array of application contexts for development cooperation in lowlands and mountain areas. When used for planning, implementation, and monitoring, GIS is a versatile and highly efficient tool, particularly in mountain areas characterized by great spatial diversity and inaccessibility. However, the establishment and application of GIS in mountain regions generally presents considerable technical challenges. Moreover, it is necessary to address specific institutional and organizational issues regarding implementation."

GIS based watershed classification in Lao P.D.R
Heinimann, Andreas
The Mekong River Commission (MRC) elaborated a spatial explicit Watershed Classification (WSC) for the Lower Mekong Basin. Based on topographic factors derived from a high-resolution Digital Terrain Model, five watershed classes are calculated, giving indication about the sensitivity to resource degradation by soil erosion. An analysis of the WSC in conjunction with forest cover data revealed that the more the 37% of Laos can be considered as critical with regard to degradation risk by soil erosion. The WSC allows spatial priority setting for watershed management and generally supports informed decision making on reconnaissance level. In the conclusions the article focuses on general considerations when GIS techniques are used for spatial decision support in a development context.

Die Jungfrau – unermesslich schön?
Droz, Marcel
Master's Thesis, University of Salzburg, Austria Die touristisch enorm attraktive Hochgebirgslandschaft des Welterbe-Gebiets steht in direkter Wechselbeziehung mit der Umgebungslandschaft. Das sich daraus ergebende Spannungsverhältnis zwischen Schutz und Nutzung lässt die langfristige Sicherung der von der UNESCO ausgezeichneten Alleinstellungsmerkmale als grosse Herausforderung erscheinen. Erschwerend für das Gebietsmanagement kommt hinzu, dass die Natur- und Kulturlandschaft durch naturbedingte Veränderungsprozesse (Stichwort Klimawandel) sowie durch den (land-)wirtschaftlichen Strukturwandel fortwährend überprägt wird. Deshalb sind Monitoring- und Controllinginstrumente erforderlich, um Veränderungen zu erkennen und ihren Einfluss auf die Werte und Potenziale des Welterbes einschätzen zu können. Während Datengrundlagen aus bestehenden Monitoringsystemen in einzelnen Bereichen eine wertvolle Ausgangslage darstellen, fehlt bislang ein operationeller Ansatz zur Identifizierung und Überwachung der von der UNESCO dem Gebiet attestierten aussergewöhnlichen natürlichen Schönheit und ästhetischen Bedeutung. Die Operationalisierung von Landschaftsästhetik stellt damit das Kernstück dieser Arbeit dar. Download

PhD Thesis, University of Bern, Switzerland "The present study seeks to generate a comparable information and knowledge base about land cover change on a mesoscale level for the entire Lower Mekong Basin. Such information is crucial to both informed decision making and the transboundary negotiations on the use and protection of the shared natural resources in regional bodies such as the Mekong River Commission. It may form the basis for achieving a common understanding regarding resource management in the Basin despite diverging national interests.

GIS applications for determining the hydrographic characteristics of rivers
Ershova, Natalia
For the identification of hydrographic characteristics of water facilities as the water collection area, the length of a river, the number of tributaries etc. the opportunities posed by GIS technologies are examined. Within the Sokuluk River Basin this task was tackled using ArcView GIS with the extension Spatial Analyst and Hydrologic Modelling modules. The potentials of the use of geo-information technologies lie within the specification and acquisition of different hydrographic characteristics, analyses, modelling of hydrologic processes and phenomena. However, some of the algorithms (i.e. determining watershed outlines) are imperfect and the tasks need to be perfomed manually in order to improve the results of hydrologic calculations.

Spatial assessment of erosion and its impact on soil fertility in the Tajik foothills
Wolfgramm, Bettina
"Efficient planning of soil conservation measures requires, first, to understand the impact of soil erosion on soil fertility with regard to local land cover classes; and second, to identify hot spots of soil erosion and bright spots of soil conservation in a spatially explicit manner. Soil organic carbon (SOC) is an important indicator of soil fertility. The aim of this study was to conduct a spatial assessment of erosion and its impact on SOC for specific land cover classes. Input data consisted of extensive ground truth, a digital elevation model and Landsat 7 imagery from two different seasons. [...] The results show distinctly lower SOC content levels on large parts of the test areas, where annual crop cultivation was dominant in the 1990s and where cultivation has now been abandoned. On the other hand, there are strong indications that afforestations and fruit orchards established in the 1980s have been successful in conserving soil resources."

Analyse de la situation de l’environnement sanitaire des quartiers défavorisés dans le tissu urbain de Yopougon a Abidjan, Cote d’Ivoire
Dongo, Kouassi
The integration into a Geographical information system (GIS) of multi-source data from QUICKBIRD imagery, ancilliary data and the results from socio-environmental investigations alowed to analyse the sanitary environment of 6 precarious settlements located along an open and exposed drainage channel, in Yopougon (Abidjan, Côte d’Ivoire). The observatory of the sanitary environment of these deprivileged areas were conducted through analysis and mapping of main factors influencing the life quality of the populations. The spatial sharpness of QUICKBIRD imagery contributed to update the land use/land cover map. Analysis of various factors witch characterise the sanitary environment reveals many insufficiences as regards the management of the sanitation system of the settlements, thus exposing the populations to illness related to sanitation like malaria and diarrhoea. The findings will permit planing appropriate measurements to overcome sanitation problems in these précarious areas. In: VertigO – La revue en sciences de l'environnement 8(3). Download
Monitoring and Modeling Crop Growth, Water Use and Production Under Dry-Land Environment North-West of Mount Kenya
Gitonga, Jeremiah Njeru Lewis
PhD Thesis, University of Bern, Switzerland "This study was initiated with the aim of using long term monitoring data collected at two representative semi arid stations to examine the impact of biophysical environment (climate and soil) and cultivation method (with and without water conservation) on crop performance (growth and production). Using the knowledge gained from this analysis, the study evaluated and adapted the Agricultural Production Simulator (APSIM) model to develop a simulation tool for the production system practiced by the smallscale farmers in the study area. The adapted APSIM model was used to examine the impact of water conservation on maize growth and production." Download
