NECESSITY OF SOIL CONSERVATION IN THE FAR NORTH,

Abstract

The carrying-out of conservation laws is ofter complicated, not only by organizational factors concerning which much has been written, but also by insufficient ability to foresee the consequences of human activity, which may variously affect different geographic topographical zones. This may be easily seen in the example of Northeast Siberia. The Maritime (Pacific Coastal) Plain from the Omoloi to the Kolyma, an extent of 1000-1100 km, is built up mainly of lacustrine-alluvial sediments containing an enormous amount of subterranean vein-ice, forming 50-60% of the volume of the top 50-100 m layer of the ground. Indeed the very existence of the plain is possible only thanks to the ground's remaining frozen. Its thawing can cause large sections of the earth's surface to sink below sea level. (Author)
