The wetlands support subsistence and livelihood to thousands of people through fishing, collecting edible plants, agriculture, irrigation and commercial fisheries, besides rich in biodiversity and maintain environmental quality of a region. The role of such wetlands in socio-economic condition of the people of their surroundings is very significant. With the increase of human population and technological development, which accelerates many activities brought about drastic change in the overall environment of the region. At the same time the nature provides ample opportunities for human settlement as well as many economic activities in the region. Encroachment, over fishing, solid and liquid waste disposal in such areas, various engineering structures constructed for different purposes are identified as some of the factors responsible for such changes. The cause and effect of such changes have been taken into account for understanding the present environmental status or ecological set-up of the Itila Jan as well as to foresee the near future situation and has been analyzed here from geographical perspective. Itila Jan is a lotic type in nature, narrow long channel, which is considered as wetland of Dimoria Development Block under Kamrup(Metro) district of Assam, India. To know about the present status of the wetlands environment, a few parameters of water and soil have been selected for analysis. The results of the water quality parameters like pH, turbidity, TS, DO, BOD, COD, ammonia(NH4+N), phosphate(PO43-) etc. and soil quality parameters like pH and OC have been found to be significant in evaluating the status of the wetlands. In the present investigation, one important wetland i.e. Itila Jan have been identified for study as it witnessed various anthropogenic and other activities near the wetlands and it has tremendously impact on the environment of wetlands. Based on the analysis of the results of relevant data a few remedial measures have been suggested for conservation and proper management of the wetlands, which may be reflected in similar wetlands of other parts of the world.
