Contrasting Benchmark Sites on Objectives
Bio‐physical and Socio‐economic Characteristics
and Implications for
Conservation and Sustainable Management of To characterize the bio‐physical, socio‐economic and
BGBD political environment of the benchmark areas to
determine constraints for adoption of conservation
and management of below‐ground biodiversity
