Tiivistelmä: | In this paper, identified are a number of essential ecosystem services, and their generation is estimated by the Swedish agricultural landscape under different production intensities. This is exemplified with data from a low-intensity period (of 1950s) and a high-intensity one (of 1990s). The services are described in qualitative and, to the extent possible, quantitative terms, and the ecological functions that support these services are identified. About 20 % of Swedish agricultural land has been removed from production during the past 40 yrs. It is argued in the paper that all of these changes affect the ability of the landscape to generate ecosystem services. Most of the measures derived in this paper indicate a loss of ecosystem services from the Swedish agricultural landscape. This is tantamount to losing an important form of 'local ecological insurance', and could lead to serious problems in a future with lower access to external resources, or with an altered energy policy. |
