Valuing critical zone services in intensively managed landscapes
The critical zone (CZ) includes the range of biophysical processes occurring from the top of the vegetation canopy to the weathering zone below the groundwater table. CZ services provide a measure to value processes that support the goods and services from landscapes. In intensively managed …
