Abstract:

A summary of the project for the MAB programme presented at the XVI session of UNESCO. Emphasis is laid on the many-sided, logical and highly accurate el1aboration of this project. Critical consideration of the preference for studies on natural ecosystems over ecosystems changed and created by man. The reason for this preference is based on the idea: a knowledge of the functioning of natural ecosystems will permit of (1) understanding the functioning of transformed ecosystems and (2) foreseeing side-effects, the degree of stability etc. of transformed ecosystems. Thus the ecosystems created by man should be formed in the image and likeness of natural ecosystems. In polemizing with this idea the following assumptions are put forward: (1) biocenoses of cultivated fields are more productive than natural ecosystems: they are essential and the area they occupy will increase: (2) a knowledge of their ecology and functioning will be obtained more rapidly by studying them directly than by comparing their life with the life of natural ecosystems: (3) the biocenoses of cultivated fields are frequently ecosystems so altered (plant monocultures) that they may often be subject to other laws and ecological regularities than natural ones: in such cases even a full knowledge of the organization (structures and functions) of natural ecosystems may be insufficient for obtaining a knowledge of the ecology of culttvated field biocenoses.
