Introduction
My interest is in applications of remote sensing technologies to the measurement and monitoring of forest ecosystems at local to regional scales; land cover/land use change, and above-ground biomass/carbon stocks using multi-sensor, multi-temporal, and object-oriented image-analysis approaches, spatial-statistical integration of field and remotely sensed data sources; understanding the dynamics of social forestry.

Over the past decade, several global maps of above-ground biomass (AGB) have been produced, but they exhibit significant differences that reduce their value for climate and carbon cycle modelling, and also for national estimates of forest carbon stocks and their changes. The number of such maps is anticipated to increase because of new satellite mi...

Droughts are scientifically studied with help of either a simple or a composite indices introduced by researchers and organizations like the Food and Agriculture Organization (FAO), World Meteorological Or...
Article
Greater variation in stand structure (i.e., individual tree size variation and stand density) is thought to promote aboveground biomass (AGB) better than species richness due to the canopy packing by different sized trees in the forest community. Here, we hypothesized that the relationships amongst species richness, stand density, individual tree s...

Forest shares 80% of total exchange of carbon between the atmosphere and the terrestrial ecosystem. Due to this monitoring of forest above ground biomass (as carbon can be calculated as 0.47 part of total biomass) has become very important. Forest above ground biomass as being the major portion of total forest biomass should be given a very careful...
