Many case studies and research works on Environmental Science related areas have been carried out by academic institutions all across the world. In this context, the Central Department of Environmental Science at Tribhuvan University has realized that documenting the findings of its students and that of its Faculties’works as well as those of other institutions on related research topics will be a contribution to the knowledge-generating and sharing process. Thus, the Department has come up with the publication of Nepal Journal of Environmental Science (Nep J Environ Sci) as an attempt to participate in the above-mentioned missions.
