Nature in farmland
The Netherlands is not particularly rich in ‘wild nature’. Comparatively, what we have is a lot of intensively used agricultural land. This means that from nature’s perspective there much to be gained by combining the ‘nature’ and ‘agriculture’ functions. Not an easy task in such a densely populated…
