Consider the following pairs regarding the Western Ghats Ecologically Sensitive Area (WGESA) notification framework and the bodies/instruments associated with it:

Pairs

1. Legal authority for declaring the WGESA — Environment (Protection) Act, 1986
2. Gadgil Committee report — recommended a bottom-up, panchayat-level grading of the entire Western Ghats as ecologically sensitive
3. Kasturirangan Committee report — recommended a smaller, geographically delineated 'natural landscape' zone for ESA protection, excluding most human-settled areas
