the crop (Denmark). Experience in Switzerland with rape seed shows not much difference in attractiveness<br />

compared to small strips of fallow. Large fields of fallow could be disapproved of due to the impression<br />

of decay and disorder during winter. Sunflower is much appreciated for its yellow flowers<br />

(Greece, Italy – northern plains). On the other hand, the perception of this could be negative in hilly<br />

regions with its own colour changes (Italy – central part).<br />

Miscanthus and willow do not offer much for variation in colour compared to fallow crops with high<br />

diversity in colour and in flowering periods.<br />

A summary of the results is given in Table 5.5, showing the overall conclusion per crop as assessed<br />

by expert judgements per country.<br />

It should be noted that these results are neither objective nor representative of the respective populations.<br />

Nonetheless they give an illustration of the impact of energy crops on landscape and confirm that<br />

the perception of people towards the impact of energy crops on the landscape varies within countries<br />

and between countries.<br />

Conclusion on visual impact of landscape changes<br />

• The method to assess the impact of biofuels on landscape by the variation is structure and colour<br />

seems a valuable method that is relatively easy to carry out and for which data are readily available.<br />

However, the method needs improvement on aspects relating to objectiveness and representativity.<br />

• The clear yellow flowers of rape seed and sunflowers are appreciated by many. However, in areas<br />

that are attractive without these flowers, their introduction may be seen as a disruption.<br />

• The positive contribution of perennials to the attractiveness of a landscape is due to their variation<br />

in structure; while the negative aspect lies in the fact that the same crop remains for many years and<br />

that in the later stages the crops may block the view as a result of their height. All in all the positive<br />

and negative aspects appear to balance each other out.<br />

5.4 Political factors<br />

How does the future for bioenergy look like? This depends on the demand for bioenergy and the space<br />

for producing it. At this moment, bioenergy is hardly an interesting energy option. It is clear however<br />

that there is a societal demand for green energy, in order to reduce the greenhouse effect. The European<br />

Commission’s White Paper “Energy for the future: renewable sources of energy” (European Commission<br />

1997) clearly states that most sources of bioenergy should be promoted with all possible means.<br />

Currently biomass accounts for 3 % of total inland energy consumption (for the EU15). If bioenergy is<br />

promoted effectively, an increase up to 8.5 % should be feasible. The White Paper also states that no<br />

more than 7 % of the agricultural area in the EU could be used for biomass crop production in a sustainable<br />

way. Moreover, surplus agricultural land can also be used for other purposes. One could extensify<br />

food production (less fertilisers and pesticides) or even go for organic food production. For this,<br />

more land is needed, due to lower yields. Another option is to expand nature areas. Clearly, the imple-
