Biodiversity as a key theme requires a fundamentally different perspective on value than is usual in the economic domain. Whoever focuses on it will certainly be able to create value: natural values. Presumably also unique natural values. The route is via the introduction of the richest possible range of plant species, which strengthen the force field of ecological succession, and possibly one or more forms of soil treatment. However, a direct reflection of these values in the sense of monetary income is doubtful, at least in the current economic context. Nature entrepreneurs can, however, generate derived economic value, for example by offering paid guided tours to visitors, or by providing additional services such as forms of hospitality. A modest source of income could also be the small-scale sale of food products to a 'self-picking' public. 


Higher biodiversity can also be expected to generate additional economic value for agricultural producers in the direct vicinity, for beekeepers, and for managing parties such as water boards or drinking water companies. The direct financial remuneration of ecosystem services such as pest prevention and water purification and storage is developing cautiously, and it remains to be seen when this will change and from what angle. In addition, the enrichment of existing forest and nature areas generates new knowledge that will be of value elsewhere through wider dissemination and exchange. However, without creative, integral and innovative arrangements, direct income in this 'branch of sport' cannot be expected. 


For the time being, the choice for local biodiversity through a food forest therefore seems to be a matter of investment, and of forms of goodwill from society. This does mean that the initiator can take the freedom to focus on specific categories of natural values or certain qualities of biodiversity - and in the meantime generate additional income such as from visits and small-scale sales.

Start your measurements

We have simplified the data and information for Welna estate a little, and also added an economic cautionary measure by skimming another 25% off the costs and benefits for the two themes where harvesting is high.

We then built a tool with which you, in your own environment, can make a pretty nice customised report that can serve as a conversation starter for your own supporters, family, financiers, etc.

Of course, this is only the beginning and the plant list consists of plants that do well on sandy soils, and we base our models on assumptions, but every year there will be more real data and all your heads will be calculating with us, so help us to make this matter more beautiful together. Enjoy.
