- Generally, the term biomass is used for all materials originating from photosynthesis. However, biomass can equally apply to animals. Conservation and management of biomass is very important. There are various ways and methods for biomass evaluation. One of these methods is remote sensing. Remote sensing provides information about biomass, but also about biodiversity and environmental factors estimation over a wide area. The great potential of remote sensing has received considerable attention over the last few decades in many different areas in biological sciences including nutrient status assessment, weed abundance, deforestation, glacial features in Arctic and Antarctic regions, depth sounding of coastal and ocean depths, and density mapping. The salient features of the book include: Several aspects of biomass study and survey Use of remote sensing for evaluation of biomass Evaluation of carbon storage in ecosystems Evaluation of primary productivity through case studies
- Generally, biomass is used for all materials originating from photosynthesis. In other words, biomass includes all plant growth, herbaceous plants, microalgae, macroalgae and aquatic plants. But biomass can equally apply to animal as well. In fact, biomass is carbon based and is composed of a mixture of organic molecules containing hydrogen, usually including atoms of oxygen, often nitrogen and also small quantities of other atoms, including alkali, alkaline earth and heavy metals. There are various ways and methods used for evaluation of biomass. One of these ways is remote sensing. Remote sensing provides information not only about biomass but also about biodiversity and environmental factors estimation over a wide area.
This information includes temporal resolution and a synopsis and digital formatting that allows for the initial processing of large amounts of data. There is a high correlation between spectral bands and vegetation parameters. The advantages of most remote sensing application for plants and phytoplankton in inland waters aim at the retrieval of the chlorophyll a, as this pigment is a useful proxy for the plant biomass. Although the pigment ratio provides an easily quantifiable approach to monitoring, doubts have been raised about interpretation of the results, so the method should only be used as one of several methods for monitoring. The shift in pigment ratio may be influenced by the fact that more old plant material is likely to be included in samples from sites where the organism is stressed. The great potential of remote sensing has received considerable attention over the last few decades in many different areas in biological science including nutrient status assessment, weed abundance, deforestation, glacial features in Arctic and Antarctic regions, depth sounding of coastal and ocean depths, and density mapping.
