Including natural value in decision-making (Nature Index)


The Nature Index tool provides a method to quantify the change in nature value within a project area that results from proposed interventions. The tool translates a nature value into nature points, to allow for a quantified comparison between alternatives. It requires four steps to determine the effect of a certain intervention on the number of nature points. The tool can be used when the feasibility of an intervention or project has to be demonstrated or when an (i.e. cost effective) alternative has to be chosen.
