Lands of industrial regions are often subjected to long-term contamination with heavy metals such as cadmium, zinc, lead, copper etc. Heavy metals circulate mostly due to water flows, and in the areas with humid (micro) climate, the heavy metal pollution propagates from sources with increased intensity because of acidic environment and soil water logging. We established that natural or artificial drainage effectively increases the washout of heavy metal pollutants due to subsurface and groundwater flows.

In the Western region of Ukraine, melioration is both of economic and social importance. The area of reclaimed lands constitutes 2.2 million ha or 24 % of the total agricultural lands in the region. Thus, melioration is of great importance for social-economic development of agro-industrial complex of the territory. Under conditions of the land reform in Ukraine, reclaimed lands were subjected to sharing and privatization causing a negative impact on efficiency of its utilization and technical conditions of the reclaimed land infrastructure.

Some scenarios of probable climatic changes in the Czech Republic and the anticipated effect of these changes on the components of the hydrologic water discharge from drained agricultural and forest catchments are studied. The function of drainage systems on selected experimental lands is examined. The effect of climatic changes on the hydrologic balance and/or on the runoff from the catchments significantly varies up to +/-150% provided that we compare the average runoff.

This report presents the results of an extra budgetary project which analyses similarities and common approaches in European national forest legislation. The forest laws of 23 countries have been examined in order to find out whether provisions are made to put into practice the following three legal issues: (1) reforestation obligations after logging through final cutting or loss of forest cover due to fire and natural calamities, (2) regulations concerning public access to forests and (3) public use of non-wood forest products occurring on forest land.

Globally, according to FRA 2000, planted forests account ed for only 5% of forest area, but up to 35% of industrial roundwood supply. This is anticipated to rise to 40-44% by 2020. Planted forests reflect a higher social, environmental and economic importance than their area would suggest. Many countries have existing planted forest data that is not based upon forest inventory, is incomplete and often outdated. Thus it is difficult to measure and plan the quantity and quality of planted forest resources and the provision of goods and services that they supply.
