Economic Development of an Area Burdened by the Surface Mining of Brown Coal , with Regard to the Principle of Sustainable Development

The article deals with an analysis of the economic development of an area which has been burdened with the surface mining of brown coal over a long period. It is an area in the northern part of the Czech Republic (Most Basin). The contribution mainly deals with the economic perspective, which is closely linked to the region’s social and environmental conditions. For the purposes of compiling the contribution, it was necessary to utilize materials relating to sustainable development and prepared statistical analyses together with the authors’ practical experiences. The model area has an unemployment rate which is among the highest in the Czech Republic (8.2%); however, it is the lowest in the last 2 years. The demographic situation contends with an ageing population and the migration of productive inhabitants inland in the direction of the capital. At the same time, there is a large proportion of socially disadvantaged people here. However, the geographic location enables cross-border cooperation with neighboring Germany and, thanks partly to updated infrastructure, a better connection is possible. GDP is currently at the level of CZK 275,214 (EUR 10,089). It has increased compared to previous years. The region’s potential lies mainly in new recreational areas, which will be created within the scope of reclamation after mining, and which will strengthen tourism and the service sector. After mining ends, around 2055, the transition to a renewable energy source will mean a further investment. Despite the negative image of the area of interest, particularly in terms of pollution as a result of mining, it is a region with the potential for sustainable economic development.


Introduction
The area of interest, which comprises the districts of Chomutov, Most, Teplice, and Ústí nad Labem (Figure 1) has been significantly affected by intensive mining and industrial activity for almost 200 years.Under the influence of mining and energy industry activities, the burden on the landscape gradually increased.
The Podkrušnohoří Basin region was deliberately designated for the interests of the increasing mining of brown coal, whose combustion became a basic energy source for the material-and energy-hungry Czech economy.The territory of the model area, which is the subject of research by the Faculty of Environment of the Jan Evangelista Purkyně University in Ústí nad Labem, takes up an area of 2276 km 2 and is home to 486 thousand inhabitants.The area is a typical industrial region which, in the late 1980s, thanks to the large-scale method of brown coal mining, was part of the "Black Triangle", then referred to as the most devastated area in Central Europe.To date, as a consequence of the transformation of the Czech economy, significant changes have taken place in the area of North Bohemia-a decline in mining and industrial manufacture, and a reduction in the intensity of agricultural production, which brings with it other specific regional disparities, i.e. social and economic differences.827 [2].
The economic development of the model area is still strongly influenced by ongoing mining activity, and local industrial activities are to a greater or lesser extent connected with the mining, transport, combustion, or other processing of brown coal.The economic subjects are also focusing on smoothing over the consequences of anthropogenic activities connected with mining-reclamation, restoration, and resocialization [4].In particular, the health impacts connected with the dustiness of the mines and with the combustion of coal affected the region's demographic curve in the 80 s and 90 s, as the increased occurrence of SO 2 and NOx in the air caused a number of lung diseases.Today, thanks to new technology, these impacts have been eliminated, but this region still has the highest occurrence of lung diseases in the Czech Republic.And from an economic perspective, the unemployment rate in the area of interest is still among the highest.Given the gradual decline of mining, investment is shifting to other sectors -recreation, agriculture, etc. Thanks to the subsequent reclamation, there is a high probability that the situation here will improve to a certain extent, but the demographic and social development does not indicate a significant improvement.The contribution deals with the link between economic development and the sustainable development of an anthropogenically burdened region.It summarizes documents which are closely related to the region's economic development, with regard to the economic pillar.At the same time, it presents the specific economic, social, and environmental problems which the model area is facing, and proposes possible solutions.Although the contribution deals with the economic, or more precisely the business development of the model area, the social and environmental situation is an essential part of the analyses.

Materials and Methods
The model area is part of a larger unit, the Ústí nad Labem Region, which comprises a total of seven districts.given territory, irrespective of their citizenship.
Regional accounts, the most important source of regional macroeconomic indicators, are a regional analogy to national accounts.Gross domestic product (GDP) is a key indicator of the development of the economy.It is a set of values added of individual institutional sectors or individual industries in activities considered by the ESA to be productive (i.e.including both market and non-market services) and net taxes on products (it is thus expressed in purchaser prices).From the point of view of use, the GDP is equal to the sum of final consumption (of households, general government, and non-profit institutions serving households), gross capital formation (fixed capital and balance of inventories and acquisitions less disposals of valuables), and the external trade balance.
Gross value added (GVA) is the sum of values added of individual industries (i.e.GDP excluding net taxes on products, which cannot be divided among individual industries).
Gross fixed capital formation (GFCF) includes the value of acquisition of both tangible and intangible fixed assets (purchased, taken over free of charge or produced by own activities), deducted by the value of its sale and the value of assets handed over free of charge.It also includes acquisition in the form of financial leasing.The target of the acquisition is always to use the fixed assets for productive activity including housing in the dwelling of its owner.Only assets used in production for a period longer than one year are fixed capital.It includes also e.g.equipment for military purposes, research and development expenditure and the like.
Net disposable income of households is an amount that households can give to final consumption, savings in the form of financial assets, and to accumulation of tangible and intangible assets.Disposable income results from the generation and distribution of income and it is the balancing item of the secondary distribution of income account.
For the needs of the international comparison, selected indicators are converted to euro currency unit.
Another primary document was the Sustainable development strategy of the Ústí nad Labem Region 2006-2020 [7].The document includes economic, social, environmental pillar and governance, which is seen as a place where sustainable development takes place.It is based on the current situation in the region.Qualification and quantification of priorities and strategic objectives is related to 2005.The document is processed according to Anglo-American planning model with small modifications and adaptation according to regional conditions.The methodical approach chosen was tested and innovated in the conditions of the

Demographic Situation
In order to evaluate the region's economic development, it is essential to analyse the demographic situation.We have processed the current data from the Statistical yearbook of the Ústí nad Labem region [5].At present, the model area in question shows a number of more or less distinct (inter)regional disparities compared to its surroundings which affect both current development and quality of life.It is an area with a highly dense population which is concentrated in cities.
The basin region has become an important area for immigration, where the number of inhabitants in cities and villages has increased 2-to 4-fold during a for the Czech Republic (134 inhabitants/km 2 ).In the district of Ústí nad Labem, which is also a regional city, 295 inhabitants live per 1 km 2 , which is the highest value in the model area.
When we look at the population status of the model Podkrušnohoří Region, we see that the highest population density over a long period has been in the Teplice district, where the number of inhabitants at the end of 2015 was 128,734.The second most populous district has-also over a long period-been Chomutov (124,335 inhabitants at the end of 2015).They are followed by the Ústí nad Labem and Most districts.The population density trend in these districts fluctuates in each one, with certain similarities.In the monitored time interval of 2000-2015, the population density of all the districts reached its maximum values in 2008-2010.In the Most and Chomutov districts, we note a decreasing trend in the number of inhabitants, while the Ústí nad Labem and Teplice districts have shown a certain stability of values in recent years (Figure 3).
During the monitored time period, the proportion of women in all the districts in question was slightly higher than that of men.The Chomutov district has long shown the largest proportion of men.The trends regarding the proportion of men in the population are not similar across the districts.However, during the past few years, the values of this indicator grew slightly for all the districts.
The ageing trend of the population is evident in all the districts in the model area.It is identical to the national and regional trend.It is best shown by the growing age index.This indicator expresses the number of persons aged 65 and over per 100 persons aged 0 -14 (usually expressed in %).The value of 100% was exceeded at a national level in 2006, while at a regional level and the level of most of the examined districts it was only exceeded in 2012 (Figure 4).Therefore, this means that the model area does not belong among the areas with the oldest populations.The smallest proportion of inhabitants of post-productive age has long been shown in the Chomutov district, with the largest proportion being in the Ústí nad Labem district.After 2009, the proportion of the population of pre-productive age began to grow slightly in all the monitored districts, with the greatest increase in the Ústí nad Labem district.

Macroeconomic Indicators
In 2014, the Ústí nad Labem Region accounted for 6.0% of the GDP of the Czech Republic, with a decreasing trend from 2012 onwards.The Gross Fixed Capital  The model area, and by extension the Ústí nad Labem Region, possesses a strategic advantage in its connection to Germany, and thanks to its dense infrastructure is one of the most connected regions to the European Union.The largest proportion of Gross Value Added in the region in 2014 was represented by services (50.1%) followed by industry (41.4%).Thanks to its mineral resources and direct connection to Germany, Ústí nad Labem is still a region of significant economic potential in the Czech Republic (Table 2).

Unemployment in the Model Area
The proportion of unemployed persons (number of accessible jobseekers aged 15 -64 per number of inhabitants aged 15 -64) was 4.90% at the end of  Over the last month, the proportion of unemployed persons decreased in almost all the districts in the region.The most significant decrease was recorded in the Teplice Region (6.3%).The smallest proportion of unemployed persons was recorded in 2008 (Figure 5).At the end of November 2016, employment offices in the Ústí nad Labem Region recorded 43,717 jobseekers, with a total of 27,831 persons in the model area.The largest number of jobseekers is in the Chomutov district (7198 persons).Since the start of the year there has been a gradual decrease of the number of jobseekers in the model area, in the Ústí nad Labem Region, and nationwide.The largest decrease in the number of jobseekers, of 1503 persons, was recorded in the Ústí nad Labem district.A significant difference in the number of jobseekers was also recorded in the Ústí nad Labem district in comparison with the same month in 2015 when 1462 more people were looking for work there.

Analysis of the Region's Economic Development with Regard to Sustainable Development
In 2004, the Ústí nad Labem Region registered for the project "Support during the Preparation of a Sustainable Development Strategy in Selected Regions of the Czech Republic", whose scope includes the pilot processing of the presented Sustainable Development Strategy for the Ústí nad Labem Region 2006-2020 (hereinafter the "SDSÚR").This strategy aims to set the framework for the region's long-term development, which will apply the principles of the sustainable development concept and will be in accordance with the human sustainable development mandate, and in the context of the sustainable development strategy  of the Czech Republic [11].Sustainable development is a European Union horizontal topic.The SDSÚR includes the economic, social, and environmental pillars, as well as the administration of public affairs, which is perceived as the space in which sustainable development takes place.It is based on the region's existing situation.In order to fulfill the main objectives of the institutional securing of sustainable development at a regional level, the Ústí nad Labem Regional Council established the Regional Development and Tourism Committee as its initiating and advisory body [6].
The following section describes results of the study concerning the public opinion of the inhabitants of the Ústí nad Labem Region within the scope of sociological research about sustainable development.In general, the inhabitants of the region regard the following problems as being the most serious: 1) The area of economic development -Do not support mining and heavy industry in the future; give preference to tourism and the service sector.
-Make more use of the vicinity of the German border for an inflow of funds into the region.
-Requalification of the workforce, and good quality infrastructure.
-Reduce unemployment in the region by supporting new entrepreneurial activity.
-Investment in road reconstruction and improving the quality of motorways.
2) Socio-cultural area -Improve the quality and availability of specialized doctors, and medical spa and rehabilitation services.
-Support the prevention of socio-pathological phenomena.
-Improve the integration of minority groups into society.
-Increase the number of completed new apartments, and restore old housing stock.
-Improve the quality of education, and increase the number of leisure activities.
3) Environmental area -Support the expansion of special protection areas in the Ústí nad Labem Region.
-Investment in environmental protection, particularly air and landscape protection.
-Reduce noise level and improve air quality in connection with traffic.
-Improve the accessibility and increase the number of containers for recycling.

SWOT Analysis of the Ústí nad Labem Region in Terms of the Economic Pillar of Sustainable Development
The SWOT analysis was made within the Sustainable development strategy of the Ústí nad Labem region 2006-2020 and the results can be summarized as follows.
Strengths: -The region's advantageous geographical location (enabling cross-border cooperation with regions in Germany; influencing the proportion of foreign visitors who prefer multi-day tourism); presence of part IV.Berlin-Prague-Brno-Bratislava-Budapest-Sofia-Istanbul Trans-European multimodal corridor (D8 motorway; 090/815 railway line; Elbe waterway); dense regional road and rail network; good transport links among important regional centres; tradition of qualification for industrial manufacture (chemical, mining, energy, and glass-making industries); significant mineral reserves; sufficient and available labour force; diverse tourist potential of the region (large proportion of protected areas in the north-east part of the region; spa centres; winter sport complexes).

Weaknesses:
-Persistence of the region's negative image; strong focus of the economy on industrial sectors with high material demands; small number of small and medium-sized enterprises which have been prospering over a long period; low proactivity by companies and enterprises in the region during the creation of a cluster system; high unemployment level, and imbalanced supply and demand in the labour market; large number of unused, derelict areas and buildings ("brownfields"); preparation of quality developmental projects and effective utilisation of EU financial instruments; utilisation of the potential of eco-friendly tourism, including the possibility of eco agrotourism within the scope of the primary sector; the growing role of corporate social responsibility; -"public-private partnership".

Risks:
-Reduction of the inflow of foreign capital, selection of unsuitable foreign investors and ineffective utilization of investments; growth in unemployment connected with the decline in heavy industry, energy industry, and mineral extraction; insufficient development of small and medium-sized enterprises in the region; outflow of highly qualified workforce; increase in passenger transport capacity, in particular private car transport, as a result of the "forced mobility of the inhabitants" caused by insufficient job opportunities in their place of residence; lower quality of tourist services and infrastructure compared to competing neighboring regions [7].The problems of the economic development of the model area of Podkrušnohoří are partly related to climatic restrictions, which result in unsuitable conditions for agriculture.Nevertheless, after mining ends, the location may be suitable for a transition to wind energy, given the favourable meteorological situation [12].The region's advantageous geographical location also enables cross-border cooperation with regions in Germany, but this is connected to the problem of the insufficient development of the technical infrastructure.However, this problem has been partly resolved thanks to the completion of the D8 motorway, which was opened in all directions on 20/09/2017 [13].This resolved the transport interconnection of the Ore Mountains with the Capital City of Prague and with Germany.At the same time, the villages on the route between these cities are no longer endangered by intensive freight transport.However, the quality of II. and III.class roads, and local routes-including railway linesremains a problem.Another issue regarding the economic development of the model area is tourism, which is negatively affected by the ongoing mining.But the planned recultivations are a unique opportunity to build new recreational zones, especially water bodies, which are created within the scope of hydrological recultivations [14].A particularly important aspect will be the construction of good quality recreational facilities, because the Ore Mountains are also visited by German citizens from Saxony.The most serious issue in the area of interest is unemployment, which is closely linked with the social situation in the entire Ústí nad Labem Region.The number of job opportunities is increasing, and unemployment has decreased considerably since 2014 [10], but it is still a region where a large proportion of unemployed persons is recorded due to a high concentration of inhabitants who misuse the Czech Republic's social system.The economic development of the Ore Mountains is also restricted by the protection of large areas for decisive sources of drinking water for the Ústí nad Labem Region and north-west Bohemia [7].At the same time, the region must contend with distinct signs of demographic regression, an ageing population, and the departure of inhabitants for the inland.In the future, it would also be appropriate to develop eco-friendly agriculture and forestry.For harmonious regional development, it is important to preserve the balance among the social, economic, and environmental pillars, which are the basic concepts for sustainable development [11].

Conclusions
The model area of the Most Basin has long been affected by the surface mining of brown coal, which in the past brought about the considerable development of industry and job opportunities; after its decline, however, economic, social, and environmental problems began to appear.The contribution is based primarily on materials dealing with sustainable development, which will ensure suitable conditions for future generations.The demographic situation in the region must contend with an ageing population, and a reduction in the number of productive persons who could strengthen the economy.The main issue is unemployment, which, however, has improved from 12% to 8.2% since 2014.Positive development is expected in the future, but modification of the social welfare system, which is being abused by some of the inhabitants of the Ústí nad Labem Region, is essential.Nevertheless, the region has the potential for economic development thanks to its advantageous location adjacent to the Free State of Saxony.The gradual addition of recultivated areas will lead to the creation of new recreational zones, which will help develop tourism and the service sector.Another opportunity for this area is its mineral reserves, though it is necessary to proceed with regard to sustainable development.Macroeconomic indicators show weak economic growth (GDP grew by almost CZK 20,000 compared to 2014).From an environmental perspective, the model area is one of the most polluted regions in the Czech Republic, but this situation is also improving.After the mining limits are reached around 2055, a transition to renewable energy sources will be necessary; these will provide new opportunities, and improve the region's economic development.
The novelty of contribution is the fact that areas devastated by coal mining may still have positive economical development and that reclamation and restoration processes could be a great chance how to make future economic development sustainable.At the same time, the contribution gives a guide whose documents and analysis should be made in order to describe economy of the chosen territory with respect to the sustainable development.This study can serve as a basis for future decision making process within the reclamation and restoration, because it summarizes strengths, weaknesses, opportunities and threats of the Ústí region.Future research should be focused on better implementation of sustainable development principles into social, economic and en-P.Vráblík
