The farmers' and non farmers'
data were collected from the periurban area of the
landscape Skåne (Southern part of Sweden) and the Mälardalen
region (the valley of Lake Mälaren; south-west Uppland, south-east
Västmanland, northern Södermanland and west of Stockholm), two
densely populated areas in Sweden (around 100 persons per km2)
with intense agricultural activities. The selected regions for this
study are important for Swedish agriculture; 25% of the Swedish
farmers live in these two areas (SCB data base, 2007a), differences
also do exist. For example, Skåne has a higher proportion of agricultural
land, higher mean temperature and humidity and lower numbers
of organic farmers as compared to Mälardalen (SCB database,
2007a; SCB, 2010).
