land use of sylhet has changed gradually. this is found from the field survey that in 1970 the area was dominated by marshy land (645.33 katha), vacant land (430.88 katha) and crop land (336.17 katha). by 1988 there was no university in the area. residential area also increased. it covered 39.11 % of total study area. now in 2007 there is a radical change noticed in the area in comparison with ...

Remote sensing has been a vastly under-utilized resource involving a multi million dollar investment. Even when utilized, the credibility has been at stake, largely because of lack of tools that can assess, visualize, and communicate accuracy and reliability in real time and at desired confidence levels. Consider an imminent scenario: What message does a remote sensing-derived landcover landuse...

Climate change is occurring: where is psychology? The conventional wisdom is that amelioration of the impacts of climate change is a matter for earth and ocean science, economics, technology, and policy-making. This article presents the basis for psychological science as a key part of the solution to the problem and describes the challenges to this both from within psychology and from other poi...

Land-cover and land-use changes are an important part of global change but determine as well livelihoods at local and regional level. The knowledge of change trajectories and possible future conditions is important for a sustainable development strategy. Further on, reliable scenarios with spatial explicit simulations are needed as planning tools for decision makers. This paper describes an exa...

Aim Whether richness patterns and determinants are consistent between common and rare species remains controversial, and the answer is fundamental for the conservation of species in vulnerable habitats. Although effects of climate and geological history on species richness have been widely explored, their relative contribution among common and rare species is poorly understood. Here, using a va...
