FUNCTION OF WATER IN THE LANDSCAPE OF THE VILLAGES IN THE PAST AND IN PRESENT, ON EXAMPLE OF VILLAGES IN LOWER SILESIA

Since ancient times, water was associated with colonization, being one of the main factors determining the localization of both cities and villages. Rivers, streams, water reservoirs were also the element contributing to the attractiveness of the rural landscape. Initially, the function of surface waters in the rural areas was limited to utility and connected with farm production. With time, the surface waters started being used for energy production and for industrial purposes. Proper management of surface waters also contributes to increase retention and reduce the risk of flooding. With time, streams and ponds became being used in mansion parks, which have been the endeavor enriching the composition. Today, rivers and water reservoirs in the villages no longer play such a significant utility and industrial role. Their function changed into mainly decorative and recreational. However, in many places the potential of using the areas adjoining rivers and ponds is not used by the village residents, which result in backfilling small water reservoirs in the villages and closing the visibility of flowing streams.


INTRODUCTION
Rural landscape was shaped by many factors.One of them were the anthropogenic processes that are a blend of cultural, social and economic factors [Marcucci 2000].Significant element of the rural landscape are the surface waters.They are the one of the most important components of the natural environment, having the impact on the attractiveness of the landscape [Iwicki 1997].Water for centuries had a profound influence on the location and development of settlements.The water was the element, which was the basis for the existence of rural residents.Initially settlements were located in close proximity or near the natural forms of surface waters.Thus, in the rural landscape there are ponds, rivers and streams, which frequently were performing utility, farm and disposal functions [Borcz, Pogodziński 1994].In rural areas, reservoirs and watercourses, although performing utility functions, influenced on a large diversity of landscapes [Wagner 2005].
With the development of civilization, the man used the water, increasingly transforming the landscape by creating new forms of water reservoirs and watercourses [Borcz, Potyrała 1993].During this time, the rank of water has increased from basic, connected with the everyday life of rural residents, to more advance use of water as an energy source, which was the basis for creating a variety of industries.The other new function of water was a decorative one, within the development of the palace and park complexes.This application appeared most frequently in the case of palace parks and gardens, which often were located deliberately near rivers.In the composition both natural elements like oxbow lakes, springs, streams and other watercourses, as well as artificial water features (ponds, canals, fountains) were used [Bernat 2003].In many villages the whole systems of water management were created, allowing retention of the excess water, as well as the possibility of obtaining it in times of shortage.Today we often underestimate the importance of water in shaping the rural landscape.Many of the old water reservoirs inside the built-up areas of the villages are backfilled without analyzing their historical role and the watercourses are covered and hidden.This causes not only the consequence of depletion of the rural landscape in terms of scenic view, but also periodic flooding of buildings, which is often a big surprise for residents.
The question must be asked whether nowadays the role of surface waters in shaping the rural landscape is appreciated and whether these resources are used by the rural society in the right way.Natural capital that brings many benefits for society are varied and multifunctional landscapes [de Groot 2006].One of the most important elements of these landscapes are surface waters.Therefore, so important objective of water management in agriculture and rural areas is protection of surface waters against improper or excessive exploitation.Now a serious threat against the achievement of these objectives is intense urbanization and fragmentation of rural areas.As a result of these processes, the existing natural, water supply and drainage systems are threatened by destruction [Kaca 2009].

Surface waters in the villages in Wisznia Mała Commune
Initially, the surface waters in the villages were used mostly for utility purposes.During this time, together with buildings and whole village development of each village, surface waters fitted to the natural environment.Work and life of the rural society in a natural way was linked with nature and its cycles.Both, the watercourses and water reservoirs had influence on rural landscape.The build-up areas in the villages were localized and shaped depending on the location of the village relative to the flowing stream.The strongest impact had the streams flowing inside the village, along the buildings, due to the need of taking into account the flood plain, without the possibility of situating any buildings there.It was necessary to build watercourse crossings to individual farms located on the other side of the stream.Sometimes two roads on both sides of the river with several major crossings connecting the two parts of the village were built.Along the rivers, high vegetation was planted, mostly fruit trees.An equally important role in the village was played by water reservoirs whose function and importance varied with changes of the rural areas.Ponds located in the center of the village, one or more, over time became in many cases fire protection reservoirs with concreted edges and gridded, metal fence.Previously available for all village residents, at this time completely cut off from the possibility of close contact with them.This process has also unfavorable visual reflection by isolation of the space and raw concrete edges of the banks.
In order to test these issues the villages from the Wisznia Mała commune from Lower Silesia Region were selected.In these villages the changes in terms of surface waters, that occurred up over time, were examined.Analyses were carried out on the basis of the comparison of the messtischblatt maps from the early twentieth century with contemporary maps and on the basis of field surveys.Also the studies conducted in 2002 [Niedźwiecka-Filipiak 2002]were used to determine whether last years had positive impact on the approach of the village residents and local authorities to the subject.In 2002 it was demonstrated that the role of surface waters had still great importance, despite the loss of a number of water reservoirs in recent years.The aim of the analysis was to determine what is the quantitative situation of water reservoirs now and also if the actions of the village residents and local authorities have recently had a positive impact on this situation.Another issue is whether the landscape potential of surface waters in the villages is used through proper management of their surroundings.
The commune of Wisznia Mała is located in the immediate vicinity of Wroclaw, bordering it from the north side.It is therefore situated in the area of strong suburbanisation processes, but it is also a potential place of recreation for Wroclaw's inhabitants [Niedźwiecka-Filipiak, 2013].Figure 1 shows on a graphical scheme the changes that have taken place in this area in comparison to the year 1942.In most of the villages the built-up areas has expanded and some of them have merged with each other (Rogoż with Kryniczna or Ligota Piękna with Wisznia Mała).The villages Raków and Cienin also underwent significant changes.These villages have been almost totally razed to the ground (Cienin) and the greater part of the land is utilized as a military training ground.Currently in part of the former Raków built-up area the Toya golf course has been built, together with a housing estate.
The studied area is located in the river basin of Widawa, which runs through the south-western part of the area.Table 1 shows that at present only one village in the whole Wisznia Mała commune has no surface waters.It is the village Piotrkowiczki.However, in the first half of the twenti-eth century, also in this village there were two small ponds within residential areas, which have not survived to the present day.In three villages there are small watercourses Ława and Mienia  flowing along the built-up areas (Mienice, Ozorowice and Strzeszów), and in one example also flowing crosswise to the village (Pierwoszów).Krzyżanowice, Psary and Szymanów are located in the vicinity of the river Widawa that flows beside the built-up areas.
During the analysis of the amount of water reservoirs in the studied localities it was concluded that within approx.100 years their number in urban areas have declined sharply, it is now a half smaller.Liquidated water reservoirs inside the old manor complexes (eg.Mienice), in the center of the village (eg.Ozorowice), the mill ponds (eg.Strzeszów) and other, particularly the small ones.Over the last 10 years the total number of all ponds inside the village has not changed, but the differences are in the various localities.Unfortunately, water reservoirs, especially those small are still being backfilled.Such examples are villages Kryniczno and Pierwoszów.In Kryniczno, following the map from year 1942, there were four water reservoirs inside the village (Figure 3).One of them was located inside the manor farm buildings, another was situated nearby and the other two had probably economic and retention functions.Even in 2002, in the village three water reservoirs were located there.The one situated near the mansion have been backfilled, but the another one located nearby was still preserved.However, it was overgrown by vegetation and neglected.The third pond, which was situated near the church, in the meantime was turned into a concrete fire protection reservoir, fenced with a mesh and became inaccessible due to the dangerous steep banks.The last pond was located within the private property, during this time its size had been reduced but the pond is now well-maintained with the addition of the bridge, however, not very visible from the road.Over the last 10 years, another two ponds were filled.The only one which remained was the one located within the private area.The new reservoir located in the vicinity of built-up areas of the village is overgrown and neglected (Figure 4).
In terms of water reservoirs situated in the immediate vicinity of the built-up areas the quantitative changes are much smaller.Their number decreased till 2002, but in the last 10 years has risen to the status of the early twentieth century (Figure 2).The biggest changes concern the development of the two recreational areas, in which new water reservoirs were created.The first is the restaurant Miłocin with water reservoir in Pier-woszów.The other is a golf course, in which there are currently six major water reservoirs and a few smaller ones, along with the Toya Golf housing estate.These sites are an example of good use of water reservoirs and creating them attractive not only for the residents of the commune, but also for Wroclaw's inhabitants and in the case of golf courses also the region.However, it should be noted that in any villages from the studied area the potential of watercourses flowing through the villages was not used to improve the quality of space around.In the village of Mienice a small part of the river surroundings within the private property have been developed in a model way (Figure 5), while within the area around the common building located by the river, the values of water haven't been taken into account.The building is fenced, cut off from the watercourse, both functionally and visually (Fig. 6).Although the public space could be enlarged by designing a descent to the water and including the river into the project, as was it done in the private property.It should be added that this is not a bad will of the inhabitants, more the lack of awareness, because the village is well cared for, and its inhabitants are active.

Contemporary functions of water reservoirs. Good practices from Poland and from abroad
The example of the right approach to the potential of existing resources and the use of surface waters in shaping the rural landscape is the village Rumbau located in Rhineland-Palatinate in Germany.The village currently has 480 residents, the  Inspired by this idea in Rumbau, next to the pond the engineers planned small oblong pool with comfortable handrails enabling easy entrance to it for all interested persons, including the elderly.Another example of good practice is an ongoing project of land development of area by a small river in the village of Ottersheim in Germany, Rhineland-Palatinate (Figure 11).This project is worth showing because without the residents of the village the realization of it would not be possible.Earlier the area adjoining the river was consisted of the private plots.Because this was the area of floodplains, there were gardens and or- chards.In the village there was little public space being favorable for integration of the inhabitants.It was therefore decided by the commune to buy the fragments of private plots adjoining the river at a symbolic price (with the consent of the inhabitants).That enabled the creation of the promenade with scenic places to rest and new public space favorable for the integration of the inhabitants.Different example of the village, where the surface waters are partially used, is the village of Bagieniec located in the commune of Świdnica.The surface waters in the village were used as early as at the beginning of the twentieth century (Figure 12).Then the inhabitants of the nearby town of Świdnica were comming to Bagieniec, searching for the ability of resting in peace among the ponds and green areas.Today, the complex of preserved ponds is used again for fishing and as a recreational area (Figure 13).

CONCLUSION
Former economic function of surface waters in the villages has changed and now they have lost their former rank.As shown on the example of the analyzed commune, the biggest changes concern small water reservoirs within residential areas, from which many were liquidated during the last 100 years.Although having the potential of performing the representative functions, being a place for recreation and the decoration of the village, only a small proportion of the small water reservoirs, which remained, is properly managed.Residents do not see their potential, rather only trouble and breeding area for onerous mosquitoes.Similarly, the potential of rivers, streams and watercourses flowing through the villages is not used.With appropriate land development they could also conduct representative and recre-ational function.The best used examples of water reservoirs are larger ponds located outside the villages.They are used as for fishing and swimming purposes.These water reservoirs are the base around which the areas with recreational and touristic function are built.
