6. Estimation of Evapotranspiration through remote sensing. Comparison between three different resolution sensors at Barrax field, Spain.
University essay from Lunds universitet/Avdelningen för Teknisk vattenresursläraAbstract : Nowadays importance of water balance regarding measurements and water cycle pathways are of prime interest in a new perspective. Global issues, like Earth warming, or regional planned uses of water, e.g. irrigation, demand an increase in accuracy and coverage of different components of the water balance. READ MORE

7. Investigating vegetation changes in the African Sahel 1982-2002 : a comparative analysis using Landsat, MODIS and AVHRR remote sensing data
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : There has been much debate concerning the concept of degradation and desertification in semi-arid lands, in particular semi-arid Sub-Saharan Africa, during the last two decades. However, recent findings suggest a consistent trend of increasing satellite-derived vegetation greenness in much of the African Sahel as interpreted from Pathfinder Advanced Very High Resolution Radiometer (AVHRR) Normalized Difference Vegetation Index (NDVI) data for the period 1982-1999.

8. The usefulness of coarse resolution satellite sensor data for identification of biomes in Kenya
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : Vegetation phenology (seasonal rhythm) is closely related to seasonal dynamics in the lower atmosphere and is therefore an important element in global climatic models and vegetation monitoring. Remote sensing is the primary means by which we can observe the dynamic characters of the earth's biosphere. READ MORE

9. The utility of NOAA AVHRR data for vegetation studies in semi-arid regions : a minor field study in the Hoanib catchment of Namibia
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : The relationship between field measurements of vegetation in a semi arid region and NDVI from the 1 km NOAA AVHRR was investigated within this study. The Hoanib catchment in the northwestern Namibia was chosen as study area. The field measurements were carried out during the month of February 1999. READ MORE

10. Different GIS and remote sensing techniques for detection of changes in vegetation cover : a MFS study in the Nam Ngum and Nam Lik catchment areas in the Lao PDR
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : The Lao People’s Democratic Republic (Lao PDR) is a small landlocked country in South-East Asia, where virgin forest still covers almost 47 % of the country’s total area (1991). Logging offers the potential to improve the economy of the Lao PDR. READ MORE
