Wood production NNK model

Ecosystem service

Biomass is the general name given to organic material from plants and animals. The agricultural industry produces biomass in forms such as animal feed, crop residues, straw and manure. Nature produces biomass as well, in the form of wood and plants, for example. Biomass may be in an unprocessed form (e.g. tree trunks), or a processed form (furniture or paper).

Biomass can be used for a variety of purposes, including agricultural fertilization, manufacturing and energy generation. The energy extracted from biomass is known as bio-energy, and it may be used as electricity, heat or gas. Biomass-based energy is obtained by combustion, gasification or fermentation of the biomass. Biomass that people eat is not referred to within the ecosystem service classification system as biomass, but as food.



Maps from the NNK-model

Five maps about biomass for energy on Atlas of Natural Capital are based on the Dutch Natural Capital Model. The maps can be viewed by clicking on the titles below.

  • Potential energy production from crops
  • Potential energy production from cultivated grassland
  • Potential energy production from forest
  • Actual energy production from crops
  • Actual energy production from forest

Technical documentation

Some maps within the ecosystem service of biomass for energy are developed according to the Dutch Natural Capital Model (NNK-model). Starting point for the modelling of these maps is the method of natuurrapport 2014 (see reference). Subsequently the model was adapted for the Dutch situation.
