| Today, sustained land use is a concern which is
in demand worldwide due to continuing erosion, a loss of bio-diversity and stress on the
water resources. Sustainability is given if the social, ecological and economic
consequences of land use show a positive effect for those concerned. In this investigation
a system of indicators is developed which serves for the classification and delimitation
of various agricultural interventions in the nature and landscape household and which
indicates the stress on the resources on a 5-grade scale. 13 stress potential indicators
are defined. The area under study is the biosphere reserve Oberlausitzer Heide and pond
landscapes in the Free State of Saxony (Federal Republic of Germany). The area comprises
27.000 ha, 9.200 ha of which being agriculturally used. The actual land use (scenario 0)
is assessed with the help of the indicator system and compared with 2 alternative systems
of land use (scenario I and II). The land use systems are based on two differing levels of
acceptance by the farmers, on prerequisites from the regulations of protected zones as
well as on supplementary considerations regarding sustained land use. The eco-logical and
economical consequences are demonstrated at the level of atotal of 95 individual
landscapes defined according to geo-ecological criteriaand criteria of use. To date, the
cultivation method of Integrated Production meets with the greatest acceptance. With the
ecological farming, the least pressure is put on the landscape household. Under the
agrarian-economic conditions presently existing, ecological farming proves to be
economically profitable. Freyer, B., Hartnagel, S., Heiz, B., Kaufmann, B. & D.
