Context:- The Haryana government has advised the district committees for ‘ground truthing’ of National Conservation Zone in the districts falling in the National Capital Region to not consider gair mumkin pahar (uncultivable land), outside Old Gurugram district, as Aravalis. To counter the above view Environmentalists have said that this was contrary to decisions taken at the NCR Planning Board meetings and would wrongly benefit real estate players and farmhouse owners, especially in Faridabad.

They continue up to Hariddwar buried under the alluvium of Ganga Plains.
