The historical role of agriculture in creating semi-natural vegetation is still not fully appreciated by many ecologists, conservationists, policy-makers or the general public. Nor is the fact that for many European landscapes and biotopes of high nature conservation value, the only practicable, socially acceptable and sustainable management involves the continuation of low-intensity farming. Consequently, too much emphasis is placed on attempting to ameliorate damaging effects of agricultural management rather than supporting ecologically sustainable low-intensity farming practices. More than 50% of Europe's most highly valued biotopes occur on low-intensity farmland. However, most of this farmland has no environmental policy directly affecting it; most management decisions are taken by farm businesses and determined primarily by European and national agricultural officials. As a result, there continues to be intensification or abandonment of traditional practices, changes which are equally damaging to the nature conservation value. However, the nature conservation importance of low-intensity farming systems is gradually being recognized. Reforms and reviews of agriculture policy are providing a variety of potential opportunities for maintaining such systems. Unfortunately, initiating change through policy is a slow process. There is therefore also a pressing need to look for other opportunities to maintain surviving systems and, where poss-. ible, to reinstate those recently lost. Although these systems may be considered low-intensity in terms of chemical inputs and productivity, they are usually high-intensity in terms of human labour. Therefore, the processes that make the low-intensity farmed countryside biologically rich and diverse must be understood, but at the same time mechanisms to make life easier and more rewarding for the people who work such farmland must be found. Ecologists and conservationists should think less of'remnants of habitat being left amongst farmland' and more of a farmland biotope for which optimum management practices need to be developed. At the same time the current emphasis on site-based conservation should be complemented by strategic initiatives that promote wise management of the wider countryside.

Development and implementation of the Norwegian monitoring programme for agricultural landscapes

The recent trend in the European Union for environmental objectives to be incorporated into agriculture policy is not simply because policy-makers in Brussels have been convinced of the important biological value of farmland. Environmental payments to farmers have become a mechanism for supporting farmers whilst at the same time not generating increased production. There are two important reasons why production must be controlled: (i) because former production policies have been so successful, many sectors have over-produced (for example, there are currently 700 000 tons of beef held in EU intervention stores) and this cannot continue: (ii) because the EU has agreed with its world trading partners (through GATT) virtually to remove production subsidies to farmers by the turn of the century. The danger, already apparent, is that environmental objectives will be misused to provide financial support to farms that are of intrinsically low biodiversity and nature conservation value. This will not be admissible under GATT and there is a danger that the misuse of environmental payments will cause major problems in the next round of GATT negotiations. There are therefore good political as well as ecological reasons for much better targeting of environmental support for farmland. Ecological studies that help us to understand the biological processes on farmland may therefore have to be used, not only for developing a more targeted environmental policy but also in the GATT negotiations.
