Tourism belongs to the industries with significant energy consumption. Visitors as well as hotel managers have, however, a positive attitude towards the responsible use of energy resources. The level of research on visitors' preferences of using different types of renewable energy is low, unlike findings on factual characteristics of conventional and renewable energies. That is why our aim was to assess visitors' preferences of environmentally friendly energy sources in hotels. Preferences of six types of renewable energy-"green" tariff energy, solar panels on the rooftops, solar panels on the ground, heat pumps, AD, wind turbine, were measured at four tourist destinations in the Czech Republic. The positive attitude of tourists towards the selected types of energy sources was confirmed. The highest preferences were found for solar panels installed on the rooftops. A typology of preferences was revealed by cluster analysis and differences between clusters were tested for independent variables. Clusters of visitors with a high and low interest in any type of renewable energy were identified as well as a cluster of visitors with interest in all types apart from solar panels installed on the ground-the visitor's origin was found as the main differentiation factor.

A basis for the identification of potential tourist development areas was defined as a combined use of the model of area load by visitors, the territorially-located database of tourist attractions, and the perception of their attractiveness by visitors. A distinctive inequality was identified in the area load and the distribution of tourist attractions. The areas of development were determined on the basis of a difference between the relative attendance and the relative attractiveness of the partial territorial units of a regular hexagonal network, sized approximately 3 km2, with a concurrent requirement of above-average total attractiveness

The paper is focused on the current status of land consolidation in Czechia. The survey is based on a questionnaire distributed electronically to municipalities and related subjects (agricultural organizations, farmers) in areas where the land consolidation has been completed, is in progress, or is under preparation. Small farmers and municipality representatives perceive the land consolidation as a measure facilitating permeability of the landscape and protection from erosion and/or from flooding. Land consolidation is important for companies in clarification of the land ownerships and as a remedy for the landscape needs. About half of the respondents believe that the measures have rather brought benefits, whereas 41% of respondents mainly highlight problems. The negative side of the land consolidation is mostly seen in the time delays and demanding administration; agribusinesses also point out complications with land management. Nevertheless, 75% of small farmers and municipalities and 62% of agribusinesses are interested in land consolidation. The main differences between small farmers and large companies consist in their attitude to reduction of the acreage of large plots and their division by common facilities.

The significance of the vulnerability of nature-rich areas with high development potential for tourism was studied using three types of data: 1) spatial distribution of tourist attractions, 2) the appeal level of these attractions, and 3) the number of visitors. The Bohemian Forest and South Bohemia were chosen as study areas. Nine types of landscape spatial appeal were identified in the study area. Two most important types were defined based on their appeal where there are rare relic features in the natural environment dominated by the presence of peat bogs and natural habitats with scrub undergrowth or virgin forests. These types were also found in the areas with the greatest potential for tourism development. However, these areas are also the most important from the point of view of nature conservation and landscape protection in Central Europe.
