4.3.4.1. Heritage services. Soilsmaintain our geological, ecological and archaeological
archive. Studies on the economic value of heritage services
are largely missing from the literature (Table 6).
Recreation services. Soils provide an environment for recreational
activities, for example ecotourism (Decaens et al., 2006) and different
sports. Recreational value is commonly assessed using the travel cost
method. However, studies of soil recreational services are largely missing
with the exception of Eastwood et al. (2000), who assessed the reduction
in recreational value due to soil erosion. The authors found it
to be 1% of the operations cost for national conservation estates in
New Zealand, amounting to id$571,720 a year
