What is the Natural Capital Index (NCI)?

Question and Answer | 18-06-2015

The Natural Capital Index (NCI) is an indicator that approximates terrestrial and aquatic biodiversity of natural ecosystems and agricultural land, respectively. The NCI considers biodiversity as a stock entity containing all original species and their corresponding abundance. The NCI is the average abundance of the original species compared to their abundance in the natural or hardly affected (pre-industrial) state. NCI is calculated by the product of the size of the remaining ecosystem (quantity) and its quality. The quality is calculated by a representative cross section of original species, the so-called shopping bag approach.
