High-mountain environment becomes gradually the attractive place for various forms of the investments. Naturally, that is not a new (neither unexpected) trend. The specific, and simultaneously the weak feature of the Tatra Mts is their insular position, since they have no equivalent from north, cast, and even from west. Among the adverse factors belongs also a relatively small area of the mountains, especially the valley systems that arc generally the most attacked by humans, due to their accessibility and hiking possibilities. The Tatra Mts lie in the field of view and interest of two gradually developing post-socialist countries (Poland and Slovakia). They have already prepared plans and particular projects for an intensive development of tourism in this area. Business and political lobby groups both latently and clearly manifest their interest in commercial utilisation of the Tatra Mts. In the paper we mention the significance of geomorphologic research and its applications for more worthwhile landscape-ecological analysis, synthesis, planning, and control of the landscape environment utilisation. Especially in the high-mountain landscape, close to timberline, the georelief attributes (static and dynamic) belong to the main limiting factors for human activity. A natural hazard assessment of actual or potential processes requires existing knowledge about the activity (intensity) of the process, procured either by direct observations (measurements) or by using simplified models combined with aerial or space photograph analysis. The measured (or calculated) parameters should be processed into a database information system. The evaluating process includes analyse of defined spatial units (morphodynamic systems), which is based on two types of criteria: criteria resulting from the human demands and interests (and conversely impacts, influences etc.), and criteria resulting from the proper dynamics of natural processes (and influences of natural conditions on each process). The hazard assessment in high-mountain area is often complicated by the risks related with the concrete estimation of losses and also casualties. Nevertheless, it becomes a component of the indicators for sustainable utilisation of natural resources.
