Forest fires pose a threat more serious than illegal felling in developing countries and are a cause of major concern for environmental security. Fires in tropical forests, though not devastating on a large scale as compared to large and infrequent fires in boreal or Mediterranean systems, still cause loss to biodiversity and economic and monetary value. In India, human-induced forest fires inc...

The area under pulse production has decreased continuously for the last 10 years in Bangladesh. With the expansion of irrigation facilities, the area allocated to production of cereal crops has increased significantly, while pulses have been pushed to marginal lands of low productivity. Additional production of pulses can be achieved by (1) increasing productivity through improved varieties, (2...

Leaf Water Content Index (LWCI) was proposed by Hunt, E. R. Jr., and et al (1987). At the beginning we tried and succeeded to develop this index for the practical application to the satellite remote sensing data such as Landsat TM. Next we performed vegetation monitoring using LWCI by SPOT Vegetation and we got same results. LWCI is not susceptible to influences from the atmospheric noise such ...

Forest policymakers, public lands managers, and scientists in the Pacific Northwest (USA) seek ways to evaluate the landscape-level effects of policies and management through the multidisciplinary development and application of spatially explicit methods and models. The Interagency Mapping and Analysis Project (IMAP) is an ongoing effort to generate landscape-wide vegetation data and models to ...

Landscape in the southern United States changed dramatically during the 1930s and the following decades when massive agricultural and abandoned logging lands were converted to forest lands through natural restoration and silviculture. The impacts of this forest restoration on hydrology were investigated in this study by conducting numerical experiments with a regional climate model. Climatic an...

Shifting cultivation is the main land-use system transforming landscapes in riverine Amazonia. Increased concentration of the human population around villages and increasing market integration during the last decades may be causing agricultural intensification. Studies have shown that agricultural intensification, i.e. higher number of swidden-fallow cycles and shorter fallow periods, reduces c...
