Changes in air temperature and precipitation and impact on agriculture
Abstract: Air temperature and precipitation are among the main factors for agricultural production. The aim of the present research work is to analyse changes in air temperature and precipitation in non-mountainous part of Southern Bulgaria in terms of the opportunities for the development of agriculture in the region. The trend in variability of seasonal and annual air temperature and precipitation is determined by the linear regression method. An analysis of the combination between air temperature and precipitation gives a tool to classify the climate according to dry and wet conditions of the territory. For this purpose the Gaussen-Bagnouls classification method is used in the present paper. In terms of air temperature, the investigated area is favourable for growing thermophilic plants. In order to investigate thoroughly the impact of climate change, the quantitative research has been complemented by a qualitative study – case study of farmers from the region of Stara Zagora. Case studies show that farmers are vulnerable to various degrees to the expected annual variability and average changes in yields depending on farm size, crop varieties and availability of irrigation.
Keywords: air temperature, precipitation, Gaussen-Bagnouls classification, case study of farmers, climate change, agriculture

The sediment transport of the Siret River during the floods from 2010
Abstract: Beginning with 2004 in the Siret River Catchment there occurred exceptional flash floods that exceeded the maximum historical values recorded, on the main river and on its tributaries (2004, the Trotuş River; 2005, the Siret River, the Trotuş River, the Bistriţa River, the Putna River; 2006 – the Clit River from the Suceava River Catchment; 2008, the Siret River, the Suceava River). The 2010 summer flood from the Siret River also falls in this category. This paper uses hydrological data (water discharge, suspended sediment discharge) between the 20th of June and 10th of July 2010 from 5 gauging stations located on the Siret River: Siret, Hutani, Lespezi, Dragesti, Lungoci, and also meteorological data (rainfall) measured at different gauging stations from the Siret River Catchment. The rainfall recorded in this time of the year in the catchment was very high, with values up to 210 l/m2 in approximately 10 days. The hydrographs of the flash flood indicate the fact that the transit of the water trough the reservoirs system from the Siret River (Rogojeşti – Bucecea and Răcăciuni – Bereşti –Călimăneşti – Movileni) reduced the maximum water discharge with values between 7-27%. The values of the maximum sediment discharge also recorded a reduction while transiting this reservoirs system with approximately 60%. The evolution of the Siret river bed channel during this flood (aggradations with values between 15-100 cm and degradations starting from 65 cm until 200 cm, in different moments of the flood) is influenced by the high values of the water and sediment discharge and by anthropogenic interventions on the river bed (pit-ballast, regularization of the river bed, reservoirs). Processing the hydrological and meteorological data recorded during the flood (20th of June – 10th of July 2010) indicates two important features of this event: the climatic variability – exemplified by the big values of precipitations from the catchment and the anthropogenic impact revealed by the transit of the flood wave and the evolution of the river bed.

Rural Development Potential of Peripheral Areas – Case Study Bochov (Bohemia)
Abstract: This paper analyzes the microregion of the town of Bochov in the Karlovy Vary Region as an example of an area located in the internal periphery of Czechia and at the same time indicating typical characteristics of the borderland, the result of postwar population transfer. Long-term population development can be characterized by a decreasing population and at the same its concentration in the center. Educational attainment statistics indicate unfavorable findings. Employment is dependent on commuting. Possible strategies include ensuring good living conditions for the population, supporting small and medium businesses, regional marketing, developing tourism and landscape stewardship, and maintaining the rural characteristic of the microregion. Microregions such as the Bochov microregion do not nor cannot have the same preconditions for development as central microregions. Their development should be focused on improving quality of life for local residents and visitors.

The Functional Transformation of Settlements in Central Serbia
Abstract: Because of its natural differences, the Goč Mountain and its foothill was respected and taken as experimental space of Central Serbia. This territory covers 402.1 square kilometers and is spread between 166 and 1127 m above the sea level. Exactly 26 settlements on the territory of the Goč Mountain and its foothill were observed. Functional characteristics were determined for every single settlement. Determination has reclined on the data of employees, by fields of activities. The results from the 1971 census were compared with those from 2002. At the end, the results were illustrated on two different ways. One has had the form of triangle and other has the form of a map. The triangle from 1971 clearly shows that the majority (53.8%) of settlements had “agriculture – industry” characteristics. After thirty years, only two settlements in the mountainous part of the territory didn’t change their characteristics. Most of the settlements have “industry – service” or “service – industry” characteristics. In comparison with the micro-regions from Central Serbia, the Goč Mountain and its foothill have very good conditions for agricultural development. More than 45% of the territory does not exceed 300 m above the sea level. Climate conditions are optimal. The space is rich in underground waters and small river streams. The agricultural fields account for more than 41% of the Goč Mountain and its foothill. About 13% of territory covers fertile alluvial soil etc. However, in 2002, there was not registered a single settlement with “agricultural” characteristics.

The Role of Borders in the Demographic Trends of Hungary
Abstract: During the period of communism, international borders were closed in Hungary. Borderland regions were in a disadvantageous situation and they strove with serious out-migration. The border regions of the counties (NUTS-3 level) face a similar situation. This paper tries to describe the population change trends of the Hungarian settlements connecting with the situation of borderlands. The settlements have been divided into three groups according to their location/function (inner border, county-border, international border) and it was inferred that the population change trends of the two border regions are similar.
