Revised EIA regulations, which came into effect in 2003, expand the possibility to require EIAs for proposed development in environmentally sensitive areas such as coasts, riverbanks and stream corridors (MoEP, 2008). Most EIAs consider species and habitat diversity, endangered species, and connectivity issues (i.e. with regard to ecological corridors). However, the terms of reference (ToRs) of EIAs only occasionally consider impacts on biodiversity directly, and EIAs seldom incorporate estimates of new development projects’ biodiversity costs and benefits.
