There many academic and policy deliberations on the nature and cause of the problem. Apparently there are solutions to the problems.
However, the approach to this issue historically is never apolitical. Often, we come across short cut solutions to the material bases of this social problem, and in the opposite sense, the social bases of the materialistic or environmental concerns.
A policy statement and a budgetary provison will not be enough to address the issue. In an era of deepening democracy, everything has been politicised and many of the concerns like this are part of everyday politics. And the powerful in the society shaped and shapes the policy and action, in mega structures as well as in micra structures. The socially excluded have been, and are excluded. Many times, a solution coming from the excluded section, when comes in sporadic cases, would be analysed in terms of economic efficiency, overlooking the social relevance.
And if does not make any political sense for a local political leader aspiring to be a Sarpanch or regional political leader in a state, the problem and the solution will not be visible to the authorities.
