In the post-war period, the area of the Sudety Mountains (also known in English as the Sudetic Mountains or the Sudetes) has been subject to two main trends regarding the transformation of the landscape in rural areas. In a first phase – intensifying above all in the period from the 1950s through to the 1970s – it was possible to observe an abrupt depopulation process, most especially affecting the areas at higher elevations. The result of this was the disappearance of many villages, or else marked decreases in numbers of both inhabitants and buildings. Knock-on effects from that included the onset of secondary succession on abandoned fields, with the result that new areas of forest have emerged in many parts of the contemporary landscape that were once cultivated fields or pastureland. Equally, from the end of the 1990s, a new trend as regards the management of rural areas in the Sudetes began to make itself apparent. This entailed an intensive development of single-family building construction, including in the form of summer homes. This development has unfortunately been chaotic in many areas, making no reference to the spatial structure originating in villages established far earlier; the result being disruption of the spatial order. At the same time, there has been no return to villages’ former functions, and nor is it possible to observe any increase in the area put to use as farmland. Nevertheless, it is true to say that many areas of what had been waste ground undergoing secondary succession have now been brought back under management, not least in connection with the implementation of joint agricultural and environmental programmes of the European Union. Various actions are today underway with a view to the typical cultural landscape of the Sudety Mountains (including the Jelenia Gora Basin) being reinstated and protected, with the rural aspect to the mountain landscape being promoted as an attribute favourable to further regional development (inter alia of the Klodzko region).
