The landscape represents a living space not only for humans but also for all living organisms, where they live in mutual interaction. Man can be considered the principal shaper of the landscape in which he resides. Human activities in the landscape take various forms (Izakovičová et al. 2017):
- placing artificial elements into the natural landscape – construction of anthropogenic buildings, areas, lines, etc. The result of this process is the creation of cultural objects (cultural landscape).
- large-scale exploitation of the natural landscape – zones of agriculture, forestry, etc. The result of this process is the creation of semi-natural landscape.
- selecting different functional zones in order to protect elements of the natural landscape (protected natural landscapes, protected zones of water resources, etc.). The result of this process is protection and preservation of natural landscape elements (natural landscape).
Man also leaves his footprint on the landscape in less obvious ways: human activities cause stress factors which lead to landscape deterioration – introduction of harmful artificial substances, soil degradation processes, etc. The result of this process is a change in the ecological conditions of natural ecosystems and their subsequent degradation. The result of this interaction of people and nature at a given time and in a given place is the creation of a landscape structure with different landscape types consisting of natural, artificial, or mixed elements. Current landscapes are a mixture of human activity with expressions of biodiversity – that is, they are biocultural landscapes (Bridgewater, Walton 1996). Biocultural diversity denotes the link between biodiversity and human diversity (Diaz et al. 2015, Hill et al. 2011). Each historical period brings certain changes and imprints elements of the landscape, shaping its character. These changes can be not only positive, but also negative, when rare and valuable landscape structures are degraded and disappeared. In Slovakia, we have so far identified a total of 26 landscape types, of which 13 were natural, 4 anthropogenic and 9 mixed biocultural landscape types.
Over the course of historical development, man has significantly influenced the structure of the natural ecosystems, which has been manifested mostly by expansion of man into space originally occupied by forest ecosystems, causing deforestation and subsequent transformation into agricultural land, especially arable soil (Izakovičová 2000). This activity created new types of landscape structures. Remains of old landscape structures have been preserved, the so-called archetypes (Hreško et al. 2010). A massive intensification of agriculture took place during collectivisation under socialism, with frequent deforestation, drying-up and ploughing-up of the land. The traditional forms of farming were destroyed along with the traditional rural lifestyle (Slavkovský 2002, Izakovičová et al. 2010). Hedges and terraced fields were ploughed up, grassland and meadows were destroyed. Progressive use of heavy machinery resulted in elimination of green infrastructure, which created unstable monotonous, intensively-used agricultural landscapes. This was particularly evident in the geographical regions with favourable nature conditions for agriculture with prevalence of lowland and flatland relief and with the most fertile soils and favourable warm climate (Feranec et al. 2010).
Urbanization together with industrialization has also had major effects on the natural ecosystems. Artificial objects were created, whether industrial or residential. New city districts and uniform apartment blocks were built. Historic centres with accompanying vegetation of considerable biocultural value were destroyed (Skanes, Bunce 1997, Medvedkov, Medvedkov 2007). A significant change in landscape types was also recorded in the transformation period, as in other post-socialist countries. Extensive construction of industrial parks and logistics centres began. On the other hand, many industrial and agricultural buildings were closing, gradually falling into disrepair and remaining abandoned, becoming “brownfields” that are aesthetically inappropriate elements in the landscape (Haase et. al. 2013). Significant changes have occurred in the rural landscape, especially in satellite villages with extensive migration of urban populations to the better conditions of the rural countryside.
The new market economy has also significantly affected the agricultural landscape since the accession of the SR to European Union. There has been a change in the types of crops being cultivated. Socio-economic conditions have encouraged the cultivation of energy crops that are not environmentally friendly (Jepsen 2015). The abandonment of farmland has affected high nature value farmland, which is the most valuable agricultural landscape type from biodiversity and biocultural point of view, although they form a low proportion of the SR by area. These areas have often been shaped by specific mountainous natural conditions and ecologically-friendly management (Dobrovodská et al. 2019). In many countries, these agricultural landscapes have been created, shaped and maintained by generations of farmers and herders using locally adapted, distinctive and often ingenious combination of management practices and techniques, and creating significant biodiversity in the area (Hong et al. 2014). Maintaining valuable habitats and landscape types requires appropriate management. Certain sites reflect specific techniques of land use that guarantee and sustain biological diversity (Bridgewater, Rotherham 2019). Many of these rare landscape structures are disappearing in Slovakia due to less favoured conditions for farming or low economic profit. They are covered in weeds, slowly being overgrown with the invasion of woody plants, and thus creating new elements of landscape structures which are inappropriate from the landscape-aesthetic point of view (Halada 2017). They are also threatened by pressure from investors to seeking to build new residential and recreational areas.
The mountain regions are the regions with the highest ecological quality, characterised by a high rate of natural ecosystems. Non-forest habitats were mainly influenced by shepherds’ activity in the past. Mountain regions with a high proportion of natural ecosystems are at risk due to the intensive development of recreation. Many forest ecosystems are affected by the construction of technical recreational infrastructure – ski slopes, hotel complexes, accommodation and catering facilities (Kuemmerle et al. 2007). Changes in forest structure also occur as a result of the impact of climate change, which causes significant damage to forest ecosystems due to wind disasters, drought, fires, pest multiplication, etc. Similarly, wetlands and water-dominated types are also negatively affected by changes in climatic conditions.
If we want to preserve this biocultural wealth and heritage, we must pay attention not only to the protection of individual types of landscape but also to their management (ELC 2011, Grunewald, Bastian 2015). In Slovakia, landscape protection is insufficient. Protection is focused only on the protection of the individual components of water, of soil, and – predominantly of biota. Protection is also predominantly biased towards the more attractive forms of biota – endemic, rare, endangered, and habitats. The most notable omission is the lack of protection for lowland and basin areas, which do not qualify for any forms of nature protection despite being very important geographical units of Slovakia (Miklós et. al. 2006). Traditionally significant protection tends to be received by mountain and high-mountain landscape types, which have been declared national parks. Separation of nature from human culture has been identified as a serious problem in the conservation of both nature and heritage (e.g. Rotherham 2008, 2014). Therefore, it would be desirable to develop and apply a new approach to protection of valuable biocultural landscape types, which is not limited to natural habitat types and wildlife, but also takes into account human activities. Many valuable types of landscapes and habitats are the result of e.g. agricultural activity and are considered part of the natural heritage (Halada et al. 2011). Many artificial, man-made landscape elements are also accompanied by the presence of valuable ecosystems, creating important biocultural types of landscape, e. g. species-rich-habitats on terraced landscapes (Kladnik et al. 2017; Slamova et al. 2015).
The protection of the biocultural landscape must respect the fact that culture and nature mutually interact. These links have developed over time through mutual adaptation and possibly co-evolution (Poe et al. 2014, Hill et al. 2011, Loh, Harmon 2005).
In order to reverse this unfavourable trend of the disappearance of valuable landscape structures, it is necessary to provide support for appropriate management. This is also possible through the rural development program. It is also necessary to ensure awareness and effective education in this area. Recognising and then appropriately managing these biocultural elements is the key to successful future conservation of nature and cultural expression. Furthermore, to achieve this objective effectively, a more integrated and joined up approach is required that leads from research, to policy, and to implementation (Bridgewater, Rotherham 2019).
