  • Tourism and sustainability in Hungary
    135-143

    Sustainable development is a very popular conception since many years. In practice there could be many difficulties.
    Economic, social and ecological systems are too complex to see all the consequences clearly. After all, sustainable criteria are indispensable for responsible planning.
    Tourism is one of the world’s dynamically developing economic sectors. But according to this development, we have to confront with a lot of negative effects, like air pollution, or mass. With globalization, the opportunities for tourism increase: thanks to modern transport, places which were too far to be accessible before are now able to be reached. But there are consequences to this expansion. Unfortunately, growth e.g. in air transport causes considerable environmental damage.
    In today’s fast-paced world, the sanctity of nature, a soundproof environment, clean air and rural life have become increasingly important. With the growth of demand and tourism globalized, these values can damage or disappear in a short time.  So, in tourism, it is vital to project development plans with sustainable principles.
    Just as other countries, in Hungary, the development of sustainable tourism is slowly becoming a priority. Fortunately, in plans for the next few years, there appear more concrete ideas on ways to make sustainable tourism grow.
    In my study, I assess Hungary’s position in sustainable tourism, examining how sustainable tourism indicators fit in sustainable development indicators and how can we measure aims of sustainable tourism.

  • The role of network administrative organizations in the development of social capital in inter-organizational food networks

    This paper is concerned with the role of network administrative organizations (NAOs) in the development of social capital in interorganizational
    networks aiming at supporting their members to innovate in the food sector through interacting with one another. A multi-case study approach is used whereby three Belgian interorganizational networks are investigated i.e. Wagralim, Réseau-Club and Flanders Food.
    Our study shows that there are many options available to NAOs to build social capital within the networks they are responsible for. We propose to categorize these options in three main distinct groups. First, NAOs may nurture the development of social capital within the network through creating ‘space’ boundary objects which appear, in our study, to be an absolute precondition for the development of interactions and hence creation of ties between network members. Second, NAOs may impact the development of social capital by favoring certain members – or set of members – over others due to their characteristics such as good reputation, possession of common past experiences, multidisciplinary  experiences, non-conflicting goals, similarity in terms of sector of activity and/or experience level and common mindset towards information exchange. Third and finally, NAOs may foster social capital development by enhancing effective communication between members on the one hand, and between members and the NAOs’ coordination and decision bodies on the other hand, via a clear mandate, network decision making
    bodies composed of members, the use of ex-post evaluations and formal governance mechanisms (e.g. legal contracts), and the selection of staff endowed with a proactive and perspective taking behavior and able to show neutrality when conflict arise. 

  • Regional economic achievements and reindustrialisation in Hajdú-Bihar county
    65-74

    The North Great Plain region is one of the backward regions of Hungary. The low level of economic development is mainly due to the lack of industrial development. The region is poor in natural resources, its main resources are land, natural gas fields, carbon dioxide, thermal water and the clay mineral stock.
    The structure of GDP per capita of the county is different than the country average mainly because of the high proportion of agriculture.
    The proportion of the industry and the building industry is not significant. Of the various service provider sectors, trade, transport and telecommunications have a small proportion, while financial and economic service providers have even lower share, which is due to the fact that these sectors are mostly concentrated in Budapest. The share of public and human service prodivers is higher than average due to the University of Debrecen.
    The GDP which expresses the economic development of the county in a complex way increased four times its previous value in nominal value between 1995–2009. However, if the real value is considered, the increase is less than 25%, as opposed to the country average, which was less than 40%.
    The most complex index of the development level of an economy is GDP expressed either in nominal or real value. If expressed in dollars, GDP is suitable for international comparison with the correction based on the purchasing power parity per person.
    The county represents 4.3% of the people employed in the industrial sector in Hungary, while its share in industrial production is only 3.3% which is lower than the regional and population share of the county within Hungary. As regards industrial production per person, Hajdú-Bihar was the 10th county in Hungary; therefore, it is considered to be a less industrialised county.
    The product structure of GDP is suitable for drawing useful development conclusions, but the result is more reliable if the income creation ability is also analysed on the basis of the employment structure.

  • Development of and Lessons from the Institution System of the Common Agricultural Policy in Slovenia

    The comprehensive agricultural policy of Slovenia during the setting-up of its agricultural institutional system for implementation of the Common Agricultural Policy has enabled the setting-up and design of the Paying Agency system to handle national and EU subsidies according to schedule. The country has acted on the advice of the European Union to use the introduction of SAPARD measures as a preparatory and experimental field for utilising subsidies after EU accession. Moreover, in addition to the importance of gaining practical experience in the field of implementation of rural development measures, Slovenia has recognised the necessity to become familiar with the application procedures for obtaining direct payments relevant for the largest group of beneficiaries, farmers. Accordingly, farmers have been practicing for 3 years how to fill in application forms, and have gained important experience before opening the most relevant resources. Also, the advisers supporting farmers to obtain subsidies have been trained during the last 3 years, in order to provide real assistance. EU agricultural subsidies are not divided among the Member States; there will be a strong competition not only with the new Member States, but also with the farmers of the more developed EU-15.
    Slovenia has done its best in order to launch its farmers – due to the different development levels of the EU-25 Member States – into this very strong competition not like pupils, but at least like mature secondary school students.

    This paper tries to find connections between sustainable landscape and spatial development policy of the Northern Great Plain region on the basis of specific examples explained in scientific literature. Searching for the common roots of spatial development and sustainability the paper explains two interpretation of sustainability from the view point of landscape, than the most significant element of current landscape change, the polarization of landscapes, will be introduced. This trend in landscape change basically determines the direction of spatial development. This paper analyses the Northern Great Plain region form two different approaches. In the first grouping the region is exposed from the view point of landscape. In the second partitioning the area is divided into subject matters based on the principles of sustainability and polarization of landscape. This research – analysing development plans and strategies – considers the current situation and the tasks of the future within the subject matters.

  • Development directions of microregional spatial environments

    The question how economic, technological and infrastructural developments, as well as products and technologies contribute to the unity and constant strengthening of the society is still unanswered both in Europe and the whole world.

    The current erosion of the society and the weakening social cohesion is a regrettable process. These phenomena are a barrier to real development processes and weaken the extension of the economic space; therefore, this negative process has to be stopped and turned into a positive direction.

    For this reason, it is increasingly urgent to work out new, feasible solutions, since it has become obvious that solutions whose sole aim is to increase profit typically weaken the indispensable unity of the society, market positions, innovation processes, as well as natural and environmental harmony.

    In this situation, we analysed and interpreted the disadvantaged and multiply disadvantaged microregional spatial environments, with special regard to the strategic developments that serve both the strengthening of the microsocieties of microregional spaces and the development of the economy and the extension of economic space.

    The identification of disadvantaged microregional spaces is basically done by means of economic indexes, but it is also important to emphasise that these indexes can only be interpreted with social indexes, as they define the situation of the microregional space and the possible development directions together.

    The constant strengthening of social unity (cohesion) and the related economic development is basically a new focal point and objective.

    The development of rural areas is a key role for the European Union and its member states as well. The rural development primarily achieved through the development of agriculture, because the main beneficiaries of the grant are the farmers. Hungary today is close to 1 million units in agriculture, but only 10% are competitive. Agriculture as an industry according to its economic characteristics needs closely managed decentralization, where the autonomy of the units remain, but there is a central governing body, which constitutes a proffesional manager function. This is a superorganization, which stay above agricultural units, called cluster.

    This paper aims to make a settlement and micro region-level analysis in case of one of Hungary’s most backwater regions, the Hungarian-Ukrainian borderland. After a brief methodological and theoretical review, it creates a complex development indicator with the help of certain ratios belonging to appropriate groups. It analyzes the exceptionally heterogeneous settlement-level values with applied statistics methods and tries to determine the role of population, population density, the distance from the nearest border-crossing point and the travel time from the centre of the micro region and the county. As its main findings the followings can be mentioned: there are significant development level differences in case of the „periphery of the periphery” micro regions which depend on the number of population, population density and the travel time from the centre of the micro regions.

  • The Target Areas of Regional Development, Tool and Institutional Background, its Present and Future Prospects

    Regional politics determines the aims of regional structures, and the tools with the institutional background on the whole necessary achieve these. Realizing the aims of regional politics is a precondition of executing the basic principles of regional development and politics. The regional institutional system for handling the decentralized financial resources has not evolved in Hungary yet. The professional institutes for preparing the programs have not been set up, and the management of execution is slowly taking shape. There are still deficiencies in the domestic application of concentration and addition principles. A number of funds are provided on a national level, that are directly or indirectly aimed at regional development. The obvious coordination among the funds is not carried out neither on a national, nor on a regional level, partly to avoid parallel consumption aims. The future of Hungarian spatial structure depends on the type of decentralization strategy the country will follow for the new resources after the accession. Total decentralization offers the most efficient solution for Hungary.

    The study is going to reveal the role of landscape potential in spatial and rural development based on the analyses of scientific literature. The target area of the research is three micro regions in Hajdú-Bihar county. In addition to the analyses of scientific literature the study pays attention to the assay of local development concepts and programmes. The conclusion of the study is that the analyses of landscape changes on micro regional level are obstructed by the lack of micro regional spatial development and substantive landscape plans.

    Agriculture is the leading national economic sector of Hajdú-Bihar county. The proportion of employees in this sector and the share of pro ducts produced in this region is above the country average. The contribution of agriculture to the GDP is 6.3%, as opposed to the average value of the country (3.3%). Based on their primary activity, 8% of the enterprises in the county are classified as agricultural and forestry companies, while this proportion is only 5.3% in the whole country.

    Nearly three quarters (71.1%) of the sowing area is occupied by maize and other cereals, mainly wheat. This proportion is slightly more than the country average (69.2%). The proportional area of oil crops - including sunflower – and roughage is nearly the same as the country average. However, there is a significant difference in vegetable production. Due to the higher intensity of vegetable production, the area occupied by vegetables is three times the country average. 19.4% of the crop products, 23.5% of animal products and living animals, 25.8% of the income generated by production factors and 29.8% of net enterprise income of Hungary originates from the North Great Plain region.

    The facilitation of creating local markets, e.g. local public food supply, satisfying the needs of food trade with local goods, the necessary awareness raising actions, secondary and higher education of experts, as well as the more specific and targeted utilisation of development resources are agricultural development tasks.

    Cultural landscapes are haunting topic of the european spatial development. Cultural landscapes as cultural heritage determine the local and regional identity. The study shows the role and the significance of the cultural landscape by the help of UNESCO World Heritage Convention, the European Spatial Development Perspective and the European Landscape Convention. The article speaks about how can we maintain and develop cross border landscapes and cultural landscapes and through introducing Érmellék it would like to draw attention to the fact that landscape level planning and development of common landscape politics are one of the main interests of Hungary. That kind of politics play an important role not only in maintaining landscapes but in the regional economic development.

    Mechanisms of regulation of litter size in pigs are complex and depend on many factors, including genetic regulation and also physiological and anatomical development of the reproductive tract in gilts. Improvement of growth rate in present breed pigs raises the question as to whether, with the development of the reproductive tract, sexual maturity would also be attained.
    The aim of the study was to assess the morphometric traits of reproductive tracts taken from gilts slaughtered at 100 kg body weight, i. e., just when they may become actively sexual mature.
    This study was concluded on 80 prepubertal gilts of the Polish Landrace (PL) breed tested at the Pig Program Testing Station. The animals were kept in individual pens with control feeding and standard management. They were slaughtered after attaining 100 kg body weight. Immediately after slaughter, the reproductive tract was removed and carefully assessed. The morphometric estimation of the reproductive tract involved the
    measurement of uterus weight with ligament, vagina-cervix length, uterine horns and oviducts length, ovaries weight, height and width. Uterus volume capacity was also determined, based on volumetric method of Kwaśnicki’s (1951) with own modification.
    All pigs were divided into three groups in respect to age at slaughter: A – below 160 days (n=38), B – from 160 to 180 days (n=28) and C – above 180 days of age (n=14). The results were elaborated statistically computing the arithmetic means (x) for every traits and standard deviations (s). One-way analysis of variance ANOVA was performed. The significance of differences between age groups was estimated using Duncan’s test.
    Calculations were performed with STATISTICA 8PL Software.
    Obtained results are presented in the tables below. The most pronounced differences in the development of the reproductive tract are dependent on the age of gilts concerning only the uterus weight (P≤0.01) and uterus vagina-cervix length (P≤0.05). Gilts at age 160-180 days attained the full stage of reproductive tract development. Differences between the compared age groups of gilts dealing with the other morphometric traits
    and ovary characteristics were statistically not significant.

    In the spirit of the Lisbon strategy, the European Union has set out the primary aims of innovation development and competitiveness. A potential method to reach these aims is to enhance the relation between science and practice and to apply scientific results. This is the case at the Agricultural Centre of the University of Debrecen as well, since the tighter and looser cooperations of the institution provide a scientific structure, which is now a significant prerequisite for Hungarian agro-innovation, primarily for rural development processes in the North Great Plain Region. The present study, based mostly on empirical findings, strives to analyze the field of activities in relation to rural development performed by the Agricultural Centre, University of Debrecen.

    The paper first negotiates the concept of multifunctionality, then the main steps of the development of the connection between agriculture and rural development are discussed. It presents the situation of a most disadvantageous sub-region that is aided by a complex program. The local rural resources are estimated by the multifunctional rural resource analysis method considering threefold function of the rural areas. It is concluded, that the land use systems and labour-intensive cropping systems have specific missions in multifunctional agriculture and rural development in the sub-region.

    The role of retaining population in agriculture is stronger and more significant in the long run in the North Great Plain Region compared to other regions. The region has a significant processing industry along with a good basis for producing raw materials, developed food processing capicity and high quality agricultural products typical of the region. The GDP in agriculture, forestry and game management is somewhat higher than the national average.
    Variety is of cardinal importance when establishing the quality of horticultural products and determining the product value. The Hungarian breeding results of apple, quince, apricot, cherry, raspberry, red and black currant are promising.
    The regulation system of EU the vegetable and fruit market is based on Retail Cooperatives Producers. With the establishment of national vegetable- and fruit production and retail organizations, the market regulation, production and quality development issues of the sector can be handled and solved. Reaching EU standards in fruit production can only be achieved with up-to-date plantation systems and breed selection. A key issue in development is establishing the required financial resources for investments and updating production. In order to reach these standards, significant state subsidies and good credit conditions are needed. By solving these tasks, the sector is expected to become self-financed without government help.
    The pursuit of safer production, improving quality and increasing yields require the establishment of up-to-date irrigation systems. The improvement of family farms, motivating land concentration is necessary for increasing average size of plants. Establishing the above mentioned conditions is important since the vegetable-fruit sector is of great significance in the employment of rurally based population, improving their living conditions and executing rural development programs.

  • Milestones in the development of agronomic management practices in crop production

    From the dawn of the history of the human race, agriculture has always been a profound activity of mankind producing food and feed as well as various plant originated materials for further processing.

    Agronomy, like any other human activity, depends on the perpetual development of knowledge and technical skills, - in a modern context – science and innovation. This paper is intended to provide the reader with information regarding the main phases of the development of agricultural production from the Neolithic societies through the early Mesopotamian and Egyptian empires to the inventions of first organised learned society of Rome. The major research findings of the past two millennia including agro-chemistry, genetics and technical development are presented.

    Such a review should not lead to any scientific conclusions, but rather a philosophical postulate similar to that of Jonathan Swift written some centuries ago: “And he gave it for his opinion, that whoever could make two ears of corn, or two blades of grass, to grow upon a spot of ground, where only one grew before, would deserve better of mankind, and do more essential service to his country, than the whole race of politicians put together”.

    In the Hungarian Rural Development Programme (RDP) climate change adaptation is addressed through the measures in Axis 1, 2, 3 and 4. Under Axis 1 farmers can receive support for farm modernisation that will help them adapt to climate change. The processing industry will also be able to use the available resources for capital expenditure on buildings and new equipment. Axis 2 and especially the soil and water package within the agrienvironmental
    measure aim to support production methods, which protect soil quality and will help adaptation to climate change. Measures of Axis 3, such as basic services for the economy and rural population, village renewal and development will provide local communities the opportunity to identify actions that can be undertaken to deal with the effects of climate change. On the other hand, the extension of forest resources contributes to climate change mitigation and enhances carbon sequestration. New methods have been elaborated to the sustainable regional water management, irrigation, water regulation, defence against internal water, and soil protection established. Water management contributes to the balance of water quantity on one side, but also to mitigating the climate change on the other.

    The development of the new economy in Hungary involves a complexity of economic and social processes. The sectoral structures and territorial location of the industy and the higher education show significant inequalities. Capital city concentration, low level of research orientation and insufficient linkages with industries are the most important barriers of the development of higher education and reindustrialization. The regional and cohesion policies need strong relations between economic restructuring and higher education development. The paper focuses on demonstrating the regional differences in these fields in southern and eastern Hungarian regions.

    The development of the Hungarian LEADER programme was organised by the Institute of Rural development, Training and Consultancy under the control of the Ministry of Rural Development. Starting the programme without earlier experiences, lead to problems, but these were solved by the efficient work of the organizing institutions. The changing European economical situation makes it necessary to review and update the Local Development Strategies along with opening the programme again. This makes the programme work more effectively with every new turn. Continusing LEADER in Hungary after 2013, by using the hungarian and Western European knowledge, can bring economical and social benefits for rural areas and for the whole nation as well.

    Common Agricultural Policy has identified three priority areas for action to protect and enhance rural heritage: (i) the preservation and development of natural farming and traditional agricultural landscapes; (ii) water management and sustainable use and (iii) dealing with climate change. Measures of Rural Development Plan in EU countries promote the development of agricultural practices for preserving the environment and safeguarding the countryside. This is achieved by targeting rural development and promoting environmental friendly, sustainable practices, like agri-environment schemes. Farmers are encouraged to continue playing a positive role in the maintenance of the countryside and the environment. Changes in total emission between 1990
    and 2007 do not show any correlation with the total GHG emission. GHG emission was reduced in Hungary, Slovakia, Lithuania, Czech Republic, Romania, Poland, Estonia and Bulgaria, where GHG efficiency is low.

  • The social basis of regional development in the North Great Plain Region

    It is a widely accepted practice in the European Union to break down countries into regions according to their stage of development, their cultural and economic characteristics. The basis of this methodology is the EU-conform MOTS system, which distinguishes territorial units on five levels. Besides the MOTS system, Hungary uses another system, too, which is the basis of our public administration, and whose roots go back to the times of King Saint Stephen: the county system. In Hungary, developmental decisions are taken by a county’s general assembly; at the same time, from an economic point of view the characteristics and competitive advantages of a county can be defined more precisely than those of a region.

    Szabolcs-Szatmár-Bereg County and Hajdu-Bihaur County may be described with completely different characteristics, albeit both of them are part of the North Great Plain Region. On a county level economically important and justified developmental areas may be mapped more precisely.

    Hajdu-Bihar County is the 4th most populous county in Hungary. With 80.2% of the population living in cities, the county is significantly urbanized. 2010 statistics show that the birth rate per 1,000 people in the county is practically the same as the birth rate of the country and that of the North Great Plain Region. Following the trends in developed countries, mothers now tend to give birth in an older age. Almost half (44.5%) of the children in Hajdu-Bihar County are born after their mother’s 30th birthday.

    The general health condition of the population of Hajdu-Bihar County can be described with various indicators. In terms of medical and hospital care no difference can be observed between regional and national data, the county’s health care does not straggle behind. In sum, with the health care system of the county, estimated life expectancy of men is higher than the regional average, and in case of women it is higher than both the regional and national average, according to the given year’s mortality.

    Children’s ratio among the county’s population is 15.9%, which is more than 1% over the national average. The ratio is higher in case of girls and boys alike. The income of the county’s population depends not only on labour income but also on social benefits. According to the analysis, the proportion of old-age pensioners and those receiving pension-like allowances within the whole population is somewhat lower in the county than the national average. The number of children receiving child-welfare and daytime care is prominent in the county.

    The number of families and children receiving child-care allowance has not changed significantly in recent years. All important elements of social benefits have increased in the last decade. The quality of life of the county’s population is largely affected by the presence (or absence) of basic infrastructure in their environment. Research conducted at the settlements of the county shows that currently the greater part of the population has access to basic public utility services which form part of everyday services. Although they affect the general quality of life, the network of roads and passenger traffic have their real significance in terms of economic development. The county’s modern, paved road-system had already been built earlier.

    Roads and pavements in inner-city areas have been paved up to 70%. The technical condition of roads and pavements can seriously impede the population’s mobility and it may hinder the development of certain settlements and districts.

  • Strategic Steps in the Sheep and Goat Branches

    The balance of the sheep and goat branches can be summarised as follows:
    If the increase in stock size, specific yields, genetic improvement and modernisation are not realised, several thousand shepherds will lose their jobs and possibilities to work, and their families will lose their only source of livelihood.
    Several hundred hectares of grassland will become weedy and the costs of crop protection will increase in these regions. Pollen pollution, the number of allergic ailments and medical costs will increase, mentioning only the main disadvantages. Its financial requirement is nearly equal to the one required for development without any essential compensation or production.
    In order to develop a competitive branch, a subsidisation of 10-20 billion HUF is needed until the accession of Hungary to the EU, depending on the scale and progressivity of development. The subsidisation and realisation of the strategic steps would result in:
    – the establishment of a registered livestock with 1.5 million ewes, which would ensure better market position for the branch in the EU (5%),
    – the establishment of a competitive and marketable branch with a production value of 15-25 billion HUF, calculated using the present price level (after accession, the branch would be self-operating and profitable, with the 6-8 billion HUF/year normative subsidisation by the EU),
    – the establishment of a genetic potential which would ensure our participation in profitable international breeding animal market, which provides extra profit,
    – the establishment of a sheep husbandry with better genetic potential and phenotypic performance, producing a quality of international level,
    – the maintenance of the workplace of more than 10.000 people (saving 3-5 billion HUF/year of the budget),
    – the maintenance of the condition of growing areas of grasslands with their advantages (crop protection and public health) whose financial effect is considerable.

    In every economic sector, the enacted and expected quality of the products strongly affects its market entry and subsistence. The aim of management is success, competitiveness and subsistence that require adequate human and material resources and enough production stock. We must also notice that the quality of tools and instruments significantly influences work productivity. This applies to both plant production and animal husbandry.

    The author researched milk production factors with methodical observation, document analysis and interviews. Data were collected with a ten-year interval, thus this assay can highlight the field, volume and sources of investments during this period and that the production stock increased in most farms and decreased in few. The data also shows the influence of investments on work productivity - there are differences between farms of equal size, so there are still ways of development.
