Agriculture still constitutes the major interaction between mankind and the natural environment. In the process of 'agricultural development' local environmental constraints may be overcome, step by step, but side-effects of this development will often lead to new environmental constraints. These new constraints may act at a larger scale, regional or national /global and may jeopardize the sustainability of the farming system itself. Table 1 gives some criteria foe judging whether farming systems may be considered 'sustainable'. Non-sustainability can be caused by not fulfilling the criteria at any of the three scales mentioned. Usually to the farmers only criteria at the local level are obvious.
