This book was released on 1997 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: By monitoring the greenness of vegetation, it may be possible to provide fire management agencies with timely information on changing forest hazard conditions. This study monitors general seasonal variation in greenness throughout the 1993 growing season in Ontario using 1-kilometre resolution Advanced Very High Resolution Radiometer ten-day composites. Data for several sample sites across Ontario's major forest regions are analyzed to report on the seasonal trends. A second aspect of the study monitors annual variation in greenness by studying four phenologically coincident scenes of the Sudbury Basin, with images taken over two decades using 50-metre-resolution LANDSAT data and analyzed to show increases in vegetation due to reductions in sulphur dioxide emissions. A simple regression equation that depends on a fuel moisture parameter was used to model and predict forest fire occurrence in the Basin area and indicate the effect of revegetation on forest fire decreases.

This book was released on 2008 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Monitoring of vegetation structure and functioning is critical to modeling terrestrial material and energy cycles, ecosystem productivity and land use/land cover dynamics within the general context of climate change. Satellite remote sensing is ideally suited for vegetation monitoring as it provides multi-decadal observations at a range of spatio-temporal scales. Consequently, there is now a pressing need to develop methodologies for generating consistent Earth System Data Records (ESDRs) from multiple satellite sensors. Leaf Area Index (LAI) and Fraction of Photosynthetically Active Radiation (FPAR) are sensor-independent measurable characteristics of vegetation. Multi-decadal global data sets of these variables generated with a physically based algorithm and of known accuracy are currently not available, although several short term research quality data sets exist. Therefore, the objective of this research was to formulate and demonstrate the performance of a synergistic approach for the retrieval of LAI/FPAR fields from measurements by multiple sensors. An algorithm to generate consistent LAI values from the Moderate Resolution Imaging Spectroradiometer (MODIS) and the Advanced Very High Resolution Radiometers (AVHRR) was developed. The approach is based on the radiative transfer theory of spectral invariants. The scale-dependent single scattering albedo and input data uncertainties govern the constrains to consistent retrievals of LAI from data of multiple sensors. A global monthly AVHRR LAI data set was generated from the corresponding Normalized Difference Vegetation Index (NDVI) fields for the period July 1981 to December 2006 using this algorithm. An evaluation of generated data set through direct comparison to ground data and inter-comparison with other LAI and surrogate data indicates good agreement both in terms of absolute values and temporal variations. The utility of the derived data set is demonstrated with a case study on characterizing climate and land use impacts on vegetation in the semi-arid tropics. It was found that large portions of the densely populated, tropical dry lands of the eastern hemisphere have experienced marked positive trends in vegetation greenness over the period 1981-2006. The results presented in this dissertation imbue confidence in the utility of this seamless, consistent satellite data product for large scale terrestrial-biosphere modeling and monitoring of global vegetation dynamics.

This book was released on 2001 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction Increasing conflagrations of forests and other lands throughout the world during the 1980s and 1990s have made fires in forest and other vegetation emerge as an important global concern. Both the number and severity of wildfires (accidental fires) and the application of fire for land-use change, seem to have increased dramatically compared to previous decades of the twentieth century. The adverse consequences of extensive wildfires cross national boundaries and have global impacts. Fire regimes are changing with climate variability and population dynamics. Satellite remote sensing technology has the potential to play an important role for monitoring fires and their consequences, as well as in operational fire management. In response to this need as well as to respond to other needs for more rapid progress in forest observation, in 1997 the Committee on Earth Observation Satellites (CEOS) initiated Global Observation of Forest Cover (GOFC) as an international pilot project to test the concepts of an Integrated Global Observing System. The GOFC program is currently part of the Global Terrestrial Observing System (GTOS). GOFC was designed to bring together data providers and information users to make information products from satellite and in-situ observations of forests more readily available worldwide. Fire Monitoring and Mapping was formed as one of three basic components of GOFC. This book contains eighteen contributions authored by scientists who represent the most active international research and development institutions, aiming at coordinating and improving international efforts for user-oriented systems and products. These papers were initially presented at a GOFC Fire Workshop held at the Joint Research Centre, Ispra. The volume is a contribution of the GOFC Forest Fire Monitoring and Mapping Implementation Team to the Interagency Task Force Working Group Wildland Fire of the UN International Strategy for Disaster Reduction (ISDR).

This book was released on 2009-09-25 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wildland fires are becoming one of the most critical environmental factors affecting a wide range of ecosystems worldwide. In Mediterranean ecosystems (including also South-Africa, California, parts of Chile and Australia), wildland fires are recurrent phenomena every summer, following the seasonal drought. As a result of changes in traditional land use practices, and the impact of recent climate warming, fires have more negative impacts in the last years, threatening lives, socio-economic and ecological values. The book describes the ecological context of fires in the Mediterranean ecosystems, and provides methods to observe fire danger conditions and fire impacts using Earth Observation and Geographic Information System technologies.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents research using high-resolution operational satellite data for monitoring and assessing numerically how to reduce the area and intensity of malaria outbreaks. Satellite data and imageries a powerful and effective tool for malaria monitoring and reduction of the number of affected people as it bypasses the limitations imposed by the dearth of near-the-ground weather data in many malaria-prone areas. With this in mind, this volume provides readers with: In-depth information in monitoring signs of malaria from operational polar-orbiting satellites Examples of country-specific models for predicting malaria area (1 and 4 km2 resolution) and intensity Information on the how the effects of climate change on malaria outbreak area and intensity can be monitored A new Vegetation Health (VH) methodology to estimate vegetation moisture, temperature and moisture/temperature conditions as indicators of malaria vector activity Advice to users on the application of VH technology for early assessments of malaria area, intensity and risk level Remote Sensing for Malaria is intended for an audience of public health practitioners, environmentalists, and students and researchers working in spatial epidemiology and disease prevention.
