Abstract
There are several frameworks which have been developed to describe the Natural Capital assessment approach. However, some of these frameworks are not fully operational in practice, and there is no unified methodology. Furthermore, calls have been made to increase the public's awareness and understanding of Natural Capital issues. To address some of these limitations it has been suggested to incorporate citizen science methods, an approach which has been increasingly growing in the Natural Capital field. The purpose of this article is to present a framework within the context of UK environmental policy as a case study. It illustrates the practicalities and the potential of using citizen science and other forms of public engagement approaches within a pre-existing Natural Capital accounting framework. This article first reviews current UK Natural Capital assessment approaches, as well as the potential for including citizen science and public engagement approaches. Combining these approaches, the inclusion of citizen science within the Natural Capital assessment framework is explored through the development of a conceptual model. We argue that the inclusion of a citizen science approach, and other forms of public engagement within the Natural Capital assessment can support in gathering a multidimensional perspective on comprehensive Natural Capital assets, and ecosystem service benefits. Knowledge generated could then be implemented to support holistic decision-making for nature-based solutions.
