1. 16. Land Surface Phenology as an indicator of performance of conservation policies like Natura2000

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Gunjan Sharma; [2016]
   Keywords : MODIS NDVI; Natura2000; Land Surface Phenology LSP ; ecological indicators; TIMESAT; trend analysis; GEM; Earth and Environmental Sciences;

   Abstract : Considering the growing pressure on various ecosystems all around the world, the development of ecological indicators for assessing the health and condition of the ecosystems has become an integral part of environmental management and policy making efforts. Such indicators do not only simplify the complex ecosystem processes but can also act as a measure of performance of a conservation policy. READ MORE

3. 17. Spatial assessment of NDVI as an indicator of desertification in Ethiopia using remote sensing and GIS

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Gezahagn Negash Seboka; [2016]
   Keywords : NDVI and Rainfall; land degradation; climate change; desertification; NOAA AVHRR; land cover; GIS; Physical Geography and Ecosystem analysis; Earth and Environmental Sciences;

   Abstract : Desertification is a serious environmental and socio-economic problem occurring at global, regional and local scale. According to Article 1(a) of the United Nations Convention to Combat Desertification (UNCCD), define the term “desertification” means “land degradation in arid, semi-arid and dry sub-humid (dry lands) areas resulting from various factors, including climatic variations and human activities”.

4. 18. Relationship between tree species composition and phenology extracted from satellite data in Swedish forests

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Stefan Arvidsson; [2015]
   Keywords : MODIS; forests mapping; fractional mapping; satellite derived phenology; GIS; Physical Geography and Ecosystem analysis; TIMESAT; NDVI; EVI; Earth and Environmental Sciences;

   Abstract : This study investigated the “relationship between tree species composition and phenology extracted from satellite data in Swedish forests”. The proposed method investigated in this study aims at mapping the fractional composition of deciduous/coniferous tree species and also the fractional composition of Norway spruce (Picea abies) and several pine (Pinus sp.

5. 19. Characterization of plant-water interaction in Kilombero River Catchment in Tanzania using Normalized Difference Vegetation Index (NDVI)

   University essay from Stockholms universitet/Institutionen för naturgeografi och kvartärgeologi (INK)

   Author : Michael Getachew Minas; [2014]
   Keywords : NDVI; NDVI classes; areal coverage; time-series analyses; hydrological data;

   Abstract : Remote-sensing based indices such as Normalized Difference Vegetation Index have yielded valuable information about plant health. As the availability of water is one of the factors that controls plant's response to their environment, it is possible to indirectly studythe hydrology of an area via vegetation indices. READ MORE
