In Eastern Himalayan region, snow melt is the major source of fresh water. Also, snow covered areas lying at low altitudes are expected to be most vulnerable to global warming. Thus, assessment of the snowmelt runoff under different climatic scenarios is important for efficient management and planning of water resources, which can be used towards mitigating the influence of climate change.

The city of Kolkata is one of the most urbanized and densely populated regions in the world and a major industrial and commercial hub of the eastern and northeastern region of India. In order to classify the seismic risk zones of Kolkata we used seismic hazard exposures on the vulnerability components, namely land use/land cover, population density, building typology, age and height.

This study presents the characteristics of aerosol black carbon (BC) from a rural continental site, Agartala, located in the North-Eastern part of India using two year measurements from September 2010 to September 2012. Diurnal and seasonal variations are examined in relation to the unique geographical location, changeable meteorological conditions and distinct source characteristics. Winter season is characterized by extremely high BC concentration (17.8 ± 9.2 µg/m3) comparable

Northeast Microbial Database (NEMiD) is a first of its kind digital database on microbial diversity from North East (NE) India, which provides information on culturable microbes (bacteria, fungi and actinomycetes) isolated from soils of the region (Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland, Tripura, Sikkim and parts of North Bengal) distributed across landscape elements (LSE) spread in various ecosystems. The database is based on the primary data through survey, isolation and
characterization of the microbes during 2008–2012.

the northeastern states of India are co-endemic for Plasmodium falciparum and P. vivax malaria. The transmission intensity is low-to-moderate resulting in intermediate to stable malaria. Malaria control prioritized P. falciparum being the predominant and life threatening infection (>70%). P. vivax malaria remained somewhat neglected. The present study provides a status report of P. vivax malaria in the northeastern States of India.

Importance of soil organic carbon (SOC) in maintaining soil productivity and natural ecosystem has been a major concern throughout the globe. SOC in the humid tropical climate becomes more important in view of undulating hilly terrain in the north eastern region of India. The major concern in such landscape is soil erosion and the necessary conservation practices. In the present study, we discuss the technique of pedometric mapping to link SOC and soil loss.
