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. Hence the thesis work used this tool to characterize the potential shifts in vegetation cover within and between years in Kilombero river catchment in Tanzania and make connection to the hydrology in the area. Separate time series analyses conducted on data pertaining to NDVI values

Abstract:

The Caspian Region includes the Caspian Sea and five littoral states: Azerbaijan, Iran, Turkmenistan, Kazakhstan and Russian. 40% of the Caspian coastal zone is arid, 69% of this territory undergone desertification according to international reports. Among the reasons are soil erosion caused by water, wind and irrigation, the salinization of soil, intense bioresources usage, and soil pollution due to oil extraction and production. Desertification is a serious problem, at global, national and local scales. It is important to know what should be sustained or developed in order to protect land fr

The need for water conservation continues to increase as global freshwater resources dwindle. In response, many golf course superintendents are implementing new methods and tools to become more frugal with their water applications. For example, scheduling irrigation using time-domain reflectometer (TDR) soil moisture sensors can decrease water usage. Still, TDR measurements are time-consuming and only cover small scales, leading to many locations being unsampled.

Abstract:

Since the early 1800's, many studies have recognized increased heat in urban areas, known as the urban heat island (UHI) effect, as one of the results of human modification to the natural landscape. UHI is related to differences in land surface temperature (LST) between rural areas and urban areas where factors of the built environment such as the thermodynamic capacities of materials, structural geometry, and heat generating activities cause increased storage and re-radiation of heat to the atmosphere. This thesis examines the correlation between factors of urbanization and differences in l

Abstract:

This work presents a geological/geomorphological analysis in the scale of 1: 100,000 of Domain Vaza Barris, using geoprocessing techniques, with the purpose of delivering data to geo-environmental planning. The study area is represented by the Vaza Barris Domain which displays a gneissic complex surfacing in two emplacements, being surrounded by a metavolcano-sedimentary cover highly deformed. This work is the mapping and the application of satellite imagery fusion techniques Landsat 8 with SRTM methodology data for the geological and geomorphological analysis by homologous zones and the use o

Student Number : 0216831W - MSc research report - School of Environmental Sciences - Faculty of Science<br>This report deals with the relationship between the NDVI obtained from the NOAA AVHRR sensor and that obtained from the MODIS sensor. The relationship is quantitatively assessed for distinct polygons over various land-cover types in the northeastern Kwa-Zulu Natal Province of South Africa. Spatial and temporal variations in the relationships are addressed and discussed with reference to spectral response, sunsensor- target geometries and atmospheric factors. Specifically, various

Through analyses of multi-temporal satellite images, it is possible to detect large-scale forest canopy changes caused by typhoon disturbances. We calculated normalized difference vegetation index (NDVI) from 3 SPOT images (10 August 2000、5 September 2000、1 July 2001) to detect vegetation changes in Fushan before and after typhoon Bilis struck Taiwan on 21~23 Aug. 2000. Results indicate that standard deviation of the NDVI was very small suggesting that the vegetative

The daily lowest temperature during the period was the lowest at Lien-hua-chi Experimental Forest since 1961 when the regular monitoring of weather started. The lowest temperature was 1oC at an elevation of 520 m above sea level and should be below 0oC at higher elevations. We analyzed the SPOT images of Lien-hua-chi Expereimental Forest of 30 December 2003, 26 February 2004, 13 March 2004, 29 December 2004, 7 March 2005, and

Abstract:

The feasibility of using optical sensors and non-nitrogen limiting reference crops to determine post-emergent nitrogen fertilizer requirements of canola was evaluated. Normalized difference vegetation index was well suited for estimating yield potential and nitrogen status. Although sensor-based nitrogen management was generally agronomically feasible for canola, the economic benefits of doing so remain uncertain because of the added cost of applying post-emergent nitrogen.<br>February 2008

Abstract:

Vegetative species diversity is under threat from environmental pressures, particularly climate change. As the impacts of climate change vary from place to place, response of vegetative species diversity to a changing climate also vary depending on geographical location. The response of vegetative species diversity under dry conditions in Zimbabwe is not well known. This study assessed the impact of climate change on vegetative species diversity under semiarid conditions of Masvingo province in Zimbabwe. This was achieved by determining climate change trends over a period of forty years
