Water quality trend of Batang Kayan and its relation to anthropogenic activities

Biological processes, anthropogenic activities and water resources within a river basin are clearly associated. Thus, water catchment is a good boundary limit to study ecological stress. Over the years, Lundu District has undergone a lot of development especially the agriculture sector. The most...
