The main objective of this work was the evaluation of TM (Thematic Mapper) and MSS (Multi Spectral Scanner) data of Landsat 1 and 5 for a large scale forest damage assessment in the black triangle region. The area covers the Krusne Hory and neighboring mountain areas (border area of Germany, Poland and the Czech Republic. A temporal comparison of land use of 1975 and 1989 of a sub area and a class
A medium scale map of the vegetation-types and their distribution in the Kärkevagge valley, located in the northern Lapland has been made based on photo-interpretation of aerial infra-red colour photographs (scale l : 60 000). Following vegetation types have been identified: High altitude vegetation, two types of wind heaths: Dryas octopetala and Empetrum hermaphroditum respectively. Three main ty
In this study, physical properties of a small glacier in Kebnekaise Mountains, northern Sweden, are investigated in order to evaluate its erosionai capacity. By definition, glacial cirques are cut out by erosion by cirque glaciers. In areas characterized by low precipitation and pemafrost, small glaciers have very low erosional capacity. Is it possible that a small glacier can excavate a cirque fo
This is a survey of the environmental impact of the eight major waste disposal sites in Malmöhus län, Sweden, as viewed from a hydrogeological perspective.
Infiltration capacity was measured with a double ring infiltrometer at 50 locations in two drainage basins in southern Zimbabwe. The infiltration capacity was tested against various factors recorded at each location to find relevant factors to use for mapping purposes. The factors recorded were land use, biotope, bedrock, landform, siteposition, ground cover, slope, aspect, organic content and tex
This is the result of a field study performed during July -September 1990 in Bakel, eastern Senegal. The village Bakel is in a semi-arid region with low agricultural productivity as a result of drought, degraded soils and excessive rainwater runoff. The thesis presents environmental conditions of the region and the water harvesting techniques introduced by a Swedish funded reforestation project. A
The purpose of the investigation was to explain the genesis of transverse ridges in the south Bolmen area, western Småland, south Sweden. A geomorphological map was made of an area with 39 transverse moraine ridges and a sedimentological study was carried out in one of them. The ridges were interpreted to be made out of mass movement till which was deposited supraglacially in troughs of a stagnant
The river of Bråån is heavely polluted by nutrient leakage from arable land. The aim of this study is to propose measures designed to reduce nutrient transport within the dranaige basin (165 km2). Leaking areas of the arable land were located and measures were suggested where they would be most effective. The west part of the basin tends to leak more through the soil profile as a result of very in
Climate and vegetation growth of an area are interrelated processes; both take place on small to global scales. However, climate change and variability impacts on vegetation in most places in the world including Tanzania is of great concern since vegetation supports many socio-economic sectors, and plays a crucial role in atmospheric greenhouse gas moderation. This study aims at investigating the
An objective method for calculating shelter effect of shelter belts - The projekt describes a method for objective classification of shelter effect for natural shelter belts. lt is aimed at producing a number of diagrams from which the shelter effect of a natural shelter, with a photographically determined porosity, can be predicted. Measurements of shelterbelt porosity has been made by analyzing
Popular science: Public transport plays an important role in enabling people to move from one place to another. The provision of information related to public transportation enables travelers to pre-plan their journeys and even save time that would have been spent asking around or looking for this information from other sources. The city of Nairobi has a population of about four million people, mo
Central America in general and Costa Rica in particular have been facing with increasing number of Chronic Kidney Disease (CKD). Experts have recently (2013) recommended spatial analysis of the relevant data for better understanding of the situation. This study was performed to evaluate geographical distribution of CKD mortality in Costa Rica through spatial analysis of CKD mortality data. The s
Aerosol particles affect the global climate due to its influence on the scattering and absorption of short-wave and long-wave radiation. The extent of the influence of aerosol particles on the climate varies a lot by time and space, and needs to be quantified. One of the most important natural sources of atmospheric particles is new particle formation (NPF). However, the contribution of NPF events
Disturbances such as wildfires are key players involved in the shape, structure and function of the ecosystems. Fire is rarely included in Dynamic global vegetation models due to their difficulty in implementing its processes and impacts associated. Therefore, it is essential to understand the variables and processes involved in fire, and to evaluate the strengths and weaknesses before going forwa
Precision agriculture requires detailed information regarding the crop status variability within a field. Remote sensing provides an efficient way to obtain such information through observing biophysical parameters, such as canopy nitrogen content, leaf coverage, and plant biomass. However, individual remote sensing sensors often fail to provide information which meets the spatial and temporal res
