This method is applied when qualitatively describing the risks of, for example, zoonoses, traffic safety and noise from livestock farming.
The qualitative method is used when few data are available for a more quantitative description, or first to examine qualitatively whether there might be a problem. If risks are flagged up, at a later stage the impacts can be worked out quantitatively (for example, for noise from livestock farms).
This method is applied at the beginning of a planning process and reveals which health aspects are relevant and how they can be taken account of when further developing the plan. Its advantage is that health receives attention early in the development of the plan and concrete opportunities for healthy layout are mentioned. It is primarily aimed at inspiring and at generating ideas. A disadvantage is that it is fairly general and difficult to translate into quantitative goals.
