Many decisions in a watershed or a river/lake basin are hampered by availability of adequate information. For example, which are the erosion hotspots in a watershed? What is the flow at various points in a basin? Which areas are susceptible to floods and droughts? What impact do upstream land use changes or future climate scenarios have on its hydrology? Answering these questions requires access to a range of multi-sectoral data that impacts multi-sectoral decisions in the basin context.
