Potential Market

Despite the fact that NFI 2 clearly attests that 35% of Swiss forests' increments are produced by hardwoods, only 28% of that volume are harvested yearly. A mere eight percent of the working capacity of Swiss sawmills is used on indigenous hardwoods;imported logs take up an additional 4%. More than 50% of the hardwood sawlogs exploited in Swiss forests is thus exported without any processing. Studies realised by «Forum for wood» have shown that an important potential market exists for local timber and especially for hardwood products. This is due not only to its aesthetic qualities, but also to the mechanical properties which allow uses in construction. The decisive factors for better marketing opportunities for hardwood are mainly found in the wood processing industries. Only a voluntary marketing promotion conducted by the whole woodworking chain can bring about a significant breakthrough for hardwoods.

Orange Revolution

The upper Theresian Valley lies along the southwest-facing ridge of the Ukrainian Carpathians. Despite expansive forestation high water levels are frequent. The forest belongs to the state and is centrally administrated. Felling is sometimes outsourced to private companies and private companies have also been founded to process the timber. Job opportunities have become fewer and illegal work is increasing. A new democratic awareness has emerged since the «Orange Revolution» in 2004. With foreign investors, however, new risks emerge. The authors recommend giving monies from forest management to the communities, the founding of new wood processing enterprises and more transparent information.

Wood Processing

Sufficient supply of woodworking with raw materials while preserving the ecology and rational use of wood is a necessary condition for the functioning of the woodworking industry as one of the key segments of the national economy. The issue is of particular importance given the deepening of world integration processes and the introduction of a moratorium on timber exports from Ukraine. It actualizes the study of the state and dynamics of the formation of raw materials potential of domestic woodworks. The purpose of the article is a structural and dynamic assessment of the economic and environmental aspects of formation of the resource potential of Ukrainian woodworks in comparison with the countries of the European Union, as well as in the regional section by types of wood. In the structure of merchantable wood harvested in Ukraine, fuel wood share increased by 4.3 pp. during 2011-2016, whereas in 2017 it increased by 3.8 pp. compared to 2016 and amounted to 61.4%. Unlike in Ukraine, in the vast majority of EU countries business timber is the basis of the structure of harvested merchantable timber. Thus, in the neighboring countries with similar forest landscape – Poland and the Czech Republic – the share of fuel wood in 2017 was 11.6% and 12.3%, in Slovakia – only 6.3%, and in the EU as a whole – 23. 2%. Hence, the significant deterioration of the structure of the harvested merchantable timber in Ukraine can be interpreted as a threat to environmental, and therefore to national security. On the other hand, the results of the assessments revealed an increase in the volume of commercial timber harvesting in Ukraine (in 18 regions) in 2018, as well as in the level of forest reproduction in the leading regions from the harvesting of merchantable timber (Zhytomyr, Kyiv and Rivne regions) and a decrease in the death rate. The restoration of the logical patterns between the dynamics of the loss of stands and the harvesting of commercial and fuel wood are signs of the beginning of positive tendencies in ensuring the preservation and rationalization of raw potential of domestic woodworks and, at the same time, improving the conditions for deepening the level of wood processing. Further authors’ research in this area will be devoted to the search for effective forms of wood industry development in Ukraine, in particular in the Western region.
