Sukumbasi Livelihood

The majority of Sukumbasis (Internally Displaced People) who live along the Manohara river make their living by collecting sand for the construction companies. I think the ramifications of people taking so much sand out of the river has to be properly studied. Among many, one of the studies says, the depletion of sand is causing the water level of the river to gosubstantially down. How much these people need to be compensated, or the ways to find alternative ways of making living for them, also needs to be properly addressed.
