Sustainable energy management – the importence of the renewable energy sources, their difficulties and chances
145-154Views:74The biggest question of the century standing before us is that if people will be able to direct the development to sustainable direction. One of the components of global problems threatening
us is the pressure that the energy management puts on the environment, which can be significantly lowered by utilizing renewable energy sources. The aim of my study is to draft the
model of a sustainable energy management, putting the renewable energy sources into it in a sensible way, regarding the possibilities of Hungary. -
Role of living bacteria and other amendment in early development of maize
53-56Views:113Different bacteria and wood ash, as a possible micro-nutrient, and liming material, was examined in our experiment on the early growth of corn seedlings.
The development of renewing energy resources includes the use of energy grasses and energy forests. The intensive land use in forestry and in agriculture may cause the acidification of soils due to the harvest, or leaching of cations. To maintain the sustainability of soils necessary to maintain it’s the buffer capacity, and pH. Beside the lime the wood ash can is one of the most effective sources to provide the sustainability of intensive land use. The soil born micro organisms play a significant role in the maintenance of soil quality. The bio fertilizer, that contains soil originated bacteria (Azotobacter, and Bacillus sp.), was used in the experiments. The plants release several organic acids by their roots lowering the soil pH, and make more available the sparingly soluble minerals. The amounts of released organic matter depend on stress intensity, as the high pH is. The soil life has a significant role to keep the soil conditions on sustainable level, since there are several similarities in nutrient uptake mechanism between the bacteria and higher plants. Advantageous effects of bio-fertilizer were observed in our experiments.
We came to the conclusion that the use of wood ash is recommended instead of lime for the improvement of acidic soils, on the evidence of its pH increasing effect. The wood ash contains several micronutrients in an optimum composition for forestry and agricultural plants. The solubility of heavy metals is very low; therefore there is no risk to use the wood ash in the agriculture and in the horticulture by our experiments. The retardation of growth at higher ash doses can be explained by the modification effect to the soil pH, as far as the original soil pH was pH 6.8, and when ash was given to the soil, the pH increases to 7.8 pH, that is unfavourable for the uptake of most nutrients.

The examination of human resources in the Hódmezővásárhely micro-region on the basis of human resource hierarchy
91-110Views:72In this paper, I deal with the examination of the situation and change of human resources through the human resource hierarchy. My research covers the Hódmezővásárhely micro-region, which includes four settlements, two towns (Hódmezővásárhely as the centre of the area and Mindszent) and two villages (Mártély and Székkutas). Based on population density the micro-region is qualified as a rural territory, which is underpinned by the micro-region’s market town and homestead like character.
I took the human resource system of Cloke and Park (1985) published in their book of Rural Resource Management as a basis of my examination and I pursued my research in consideration of Fehér’s (2005) researches related to rural economy. The system of human resources provided a hierarchical and logical framework for my examination. In the course of the research I made analyses along the three levels of human resources concerning the micro-region and its settlements.
During the examination of the human resources of the Hódmezővásárhely micro-region I pointed out some negative changes and situations which unfavourably influence the socio-economic processes of the territory and its settlements. All this reveal that the human resources are not only factors of the economy of the micro-region as a rural economy but at the same time they are areas to be developed. The living standard (welfare) of the people living in the area and their quality of life (well-being) depend on the development and level of the different dimensions of the human resources largely. For that very reason there is a need for coordinated development of the human resources and the related fields with respect to the cause-effect relations.
My research contributes to the better cognition of rural resources of the Hódmezővásárhely micro-region, without this a rational improvement and sustainable development of the micro-region and its settlements based on inner resources cannot be imagined. -
Public opinion on the settlements’ environment and the use of renewable energy sources in the Micro-region of Gyöngyös
267-272Views:59This paper intends to give an overview on some results of our studies carried out on the public opinion of the above aspects (settlements’
comfort level and the use of renewable energy sources) directly or indirectly linked to the topic of climate change and possible adaptations.
These studies were carried out by applying questionnaire survey in the (altogether 25) settlements of the Gyöngyös Micro-region.
Knowledge on general human perceptions related to climate change and its impacts is considered to be important as it should advance the
elaboration of adaptation and applied scientific works. They are highly required as rural areas, due to their closer relationship (dependence)
to the physical environment, are more susceptible to changes resultant from the climate change with their possibilities to adaptation also
being impeded.
The beauty of environment plays an important role in the settlements studied within the micro-region with more than two third of pollees
opting the environment as a factor they most proud of, especially among those residing in the villages for more than 10 years. It can be
presumed that any change in this environment would greatly impact their everyday life and emotional relationship to their home villages. The
overall picture after analysing the public opinion on the use of renewable energy source (as possible way of adaptation to the impacts of
climate change) is rather controversial. Even basic knowledge and information are limited regarding the relevant technologies calling
attention to the importance of raising environmental awareness and providing full information seems to be essential and should be
implemented, through the media and education. -
Comparative analysis in residential property price level and price dynamics in urban and rural areas of Hajdú-Bihar County
85-90Views:113In modern market economies residential real estate prices, price shifts and their correlations with macroeconomic factors are surveyed quite frequently. However, in contrast with the wide scope of foreign examples, so far existing analyses in Hungary have ignored examining relation and extensity of macroeconomic indicators and failed to examine their effect on real estate pricing. The scope of this survey is to highlight these potential correlations and thus develop new aspects of analysis. Although the examination needs further extension both in time and space, the results of this survey may help to understand the importance of the responsible management of the most precious element of national wealth from the perspective of sustainable rural development.
Based on my preliminary results, there exists a strong correlation between the number of inhabitants of a settlement and the average real estate prices. Nevertheless, the correlation seems to be significant only for cities. In the case of smaller settlements the correlation still exists but at a lower level. As opposed to the results of former publications and my own expectations, no direct link could be tackled between the amount of income tax paid by private individuals and real estate prices either in the cities or in the villages within the territory and time span examined in my analysis. Although this correlation is measurable on a macro-economic level, my micro-regional analyses revealed the complexity of asset pricing and price volatility. Continuing this survey, my goal is to identify the hidden factors influencing real estate prices, whose thorough mapping may promote conscious rural development.

New challenges in soil management
91-92Views:189Soil management represents two important tasks that are harmonization of the soil protection with demands of the crop to be grown on the given land under prevailing farming condition. Further goals are to preserve and/or develop the soil physical, biological and chemical condition and to avoid the unfavourable changes of the soil biological activity and the soil structure. Classical authors emphasised the importance of creating proper seedbed for plants. In the physical approach, tillage was believed to play an important role in controlling soil processes. Consequently, the period of several centuries dominated by this approach is referred to as the era of crop-oriented tillage (Birkás et al., 2017). The overestimation of the importance of crop requirements resulted in damaging the soils, which inevitably led to turn to the soil-focused tillage. Since the first years of climate change, as the new trends have raised concern, tillage must be turned into a climate-focused effort with the aim of reducing climate-induced stresses through improving soil quality.The development of soil management has always been determined by the economical background. At the same time, deteriorating site conditions have contributed to the conception of new tillage trends by forcing producers to find new solutions (e.g. dry farming theory in the past or adaptable tillage theory nowadays). Győrffy (2009) recited the most important keywords were listed in 2001 and that seemed to be important in the future of crop production. These keywords (endeavours) were as follows:− Biofarming, organic farming, alternative farming, biodynamic farming, low input sustainable agriculture;− Mid-tech farming, sustainable agriculture, soil conservation farming, no till farming, environmentally sound, environmentally friendly, diversity farming;− Crop production system, integrated pest management, integrated farming, high-tech farming;− Site specific production, site-specific technology, spatial variable technology, satellite farming;− Precision farming.Győrffy’s prognosis proved to be realistic and the efforts mentioned above have mostly been implemented. New challenges have also appeared in soil management in relation to the last decades. The most important endeavours for the future are:1) Preserving climate-induced stresses endangering soils.2) Turn to use climate mitigation soil tillage and crop production systems.3) Applying soil management methods are adaptable to the different soil moisture content (over dried or wet may be quite common).4) Use effectual water conservation tillage.5) Use soil condition specific tillage depth and method.6) Adapting the water and soil conservation methods in irrigation.7) Preserving and improving soil organic matter content by tillage and crop production systems.8) Considering that stubble residues are matter for soil protection, humus source and earthworm’ feed.9) Site-specific adoption of green manure and cover crops.10) Applying site-adopted (precision) fertilization and crop protection. Considering the development in agriculture, new endeavours will occur before long. -
The Effect of Atmosperical Aridity on the Changes of Quantitative Parameters of Horticultural and Arable Crops
40-45Views:104The occurence of atmospherical drought causes serious water-supply problems in the most cases of our domestic agricultural plant species. This paper was studied, how can we quantificate the atmospherical drought, with the help of a low input (relative humidityof the air, temperature) index. If this index (LSZI) characterized the atmospherical drought well, it will suitable to estimate the yield amount of agricultural plants.
The index elaborated by the authors was tested on county average crop yield of 14 agricultural plant species. Moreover we compared the atmospherical drought index (LSZI) to other aridity parameters, how suitable for estimate the yield amount.
Result of experiments show that, the atmospherical drought index (LSZI) can be used well by several agricultural plant species in especially coern and sugar-beet to estimate yield amount. Excellent results were found by comparison to other aridity indexes, this means it is worth using in the aridity researches in the future. -
Economic questions of precision maize production on chernozem soil
293-296Views:122It is one of the main topical objective to establish the conditions of sustainable farming. The sustainable development in crop production also calls for the harmony of satisfying human needs and providing the protection of environmental and natural resources; therefore, the maximum consideratio of production site endowments, the common implementation of production needs and environmental protection aims, the minimum load on the environment and economicalness. Precision farmin encompasses the farming method which is adjusted to the given production site, the changing technology in a given plot, the integrated crop protection, cutting edge technologies, remote sensing, GIS, geostatistics, the change
of the mechanisation of crop production, and the application of information technology novelties in crop production. Modern technology increases efficiency and reduces costs. The efficiency of crop production increases by reducing losses and the farmer has access to a better decision support information technology system. In addition, we consider it necessary to examine the two currently most important economic issues: “is it worth it?” and “how much does it cost?”. During the analysis of agricultural technologies, we used the precision crop production experiment database of KITE Zrt. and the Institute for Land Utilisation, Regional Development and Technology of the Centre for Agricultural and Applied Economic Sciences of the University of Debrecen.
During our analytical work, we examined three technological alternatives on two soil types (chernozem and meadow). The first technology is the currently used autumn ploughing cultivation. We extended our analyses to the economic evaluation of satellite navigationassisted ploughing and strip till systems which prefer moisture saving. On chernozem soil, of the satellite-based technological alternatives, the autumn ploughing cultivation provided higher income than strip till. In years with average precipitation supply, we recommend the precision autumn ploughing technological alternative on chernozem soils in the future. On meadow soil, the strip till cultivation technology has more favourable economical results than the autumn ploughing. On soils with high plasticity – considering the high time and energy demand of cultivation and the short amoung of time available for cultivation – we recommend to use strip till technologies. -
The Role and Significance of Soil Analyses in Plant Nutrition and Environmental Protection
3-8Views:80Hungary has a rich history of soil analyses and soil mapping. Our main tasks today are the preservation of soil fertility as well as balancing the goals of production and environmental protection. The main requirement of agricultural production is to adapt to ecological and economic conditions.
In a series of consultative meetings in the past seven years, representatives from Central and Eastern Europe have analyzed nutrient management practices in their respective countries. According to a joint memorandum agreed upon in 2000, in the countries awaiting accession, the quantity of nutrients used per hectare is considerably smaller than the Western-European usage targeted through special subsidies. The current low nutrient usage contradicts the principles of sustainability and that of the efficient use of resources, jeopardizing soil fertility.
In Hungary, the use of inorganic fertilizers underwent a dynamic development, which manifested itself in an almost tenfold usage growth between 1960 and 1985. This growth slowed down somewhat between 1985 and 1990 and then reduced dramatically after 1990, reaching record lows at the usage levels of the 60s. The nutrient supply has had a negative balance for the last 15 years.
The increasing and then decreasing usage trends can equally be detected in the domestic yield averages of wheat and corn as well as in the nutrient supply of soils. Yields were the largest when usage levels were the highest, and decreased thereafter. Draughts have also contributed to smaller yields. The dramatic decrease in the use of inorganic fertilizers when adequate organic fertilizers are lacking endangers our soils’ fertility.
About 50% of soils in Hungary are acidic. Acidity is mostly determined by soil formation, but especially on soils with a low buffering capacity, this acidity may intensify due to inorganic fertilizers. Sustainable agriculture requires the chemical improvement of acidic soils. According to their y1 values, the majority of our acidic soils need to be improved. This chemical soil remediation is required in 15% of the acidic soils, while it’s recommended for another 20% of these soils.
Results of the analyses conducted in the framework of the soil-monitoring system set up in Hungary in 1992 show that in 95% of the analyzed samples, the toxic element content is below the allowable limit. Cultivated areas are not contaminated; toxicity above the legal level was found only in specific high-risk sampling areas: in the vicinity of industry, due to local overload. The basic principle of sustainable agriculture is to preserve soil fertility without undue strain on the environment. The intensity of the production needs to be considered according to the conditions of the site; i.e.; nutrient management needs to be site-specific. It is recommended to differentiate three types of cultivated land in terms of environmental sensitivity: areas with favorable conditions, endangered areas, and protected areas, and then to adopt nutrient management practices accordingly. To meet all the above-mentioned goals is impossible without systematic soil analysis. Tests conducted by the national monitoring system cannot replace regular field measurements. -

The recent state of cryopreservation techniques for ex-situ gene conservation and breeding purposes in small ruminants: A review
81-87Views:269The viewpoint of the recent cryopreservation techniques (CT) suggests the use of a reduced volume of cryopreservation solution, high concentration of cryoprotectants and ultra-rapid cooling and warming rates help to reduce cryo-injury and maximize the viability of the preserved animal genetic resources (AnGR). The CT had now become widely accepted as one of the best methods of choice for the ex-situ conservation of AnGR due to its high success rate recorded and no-invasive nature as compared to the conventional slow rate freezing (CSRF). Rapid advances and wide acceptability of the use of assisted reproductive technologies (ART’s) particularly artificial insemination (AI) in animal breeding had resulted in a greater loss of a large number of good quality genes in virtually almost all the native breeds of animals across the globe. Small ruminant (SR) animals are not an exception in such present predicaments situation of erosion and dilution of the valuable AnGR among the native breeds. As a result of this, 148 and 16 breeds of sheep and goats respectively have already become extinct in Europe and the Caucasus. In view of the aforementioned situation, the present review aimed at exploring some of the current states of development, roles played and potentials of CT in the conservation of SR genes and genome for the immediate and future breeding purposes for sustainable development. It basically covers; animal genetic resource, the need to conserve AnGR, tools for ex situ in vitro conservation of AnGR and recent developments in breeding and cryopreservation of SR AnGR.
Cryopreservation is playing a pivotal role in ex-situ gene conservation of AnGR. Decline in genetic diversity among SR breed population was high in Europe and the Caucasus. There is therefore, need for improvent on current stringent measures on conservation of AnGR in this region of the world.

Status and Prospects of Integrated Pest Management in Apple Production in Hungary
307-316Views:81Farming methods supporting the ecological function of agriculture will play an even more dominant role in the near future than they do now, as much in Hungary as in the rest of the EU.
Several farming techniques supporting sustainable development have already evolved, and in this essay, I deal with integrated production i.e. integrated fruit production in Hungary and its perspectives. I analyze both European and Hungarian regulations on integrated production and their development.
It is obvious that in the orchards of Europe, integrated production is gaining ground. We can expect the increased spread of this western trend to Hungary, too, because one of the conditions for remaining on the market will be a product from integrated production. However, we cannot expect any rapid increase in the future. In my opinion, there are three ways to propagate integrated production:
− changes in the approach of farmers;
− vocational training of farmers because of the greater „knowledge-demand”; improving the consultant network;
− strict monitoring of the production process. -
Renewable energy resources in the EU (Policy scenario)
143-146Views:103The use of renewable energies has a long past, even though its share of the total energy use is rather low in European terms. However, the tendencies are definitely favourable which is further strengthened by the dedication of the European Union to sustainable development and combat against climate change. The European Union is on the right track in achieving its goal which is to be able to cover 20% its energy need from renewable energy resources by 2020. The increased use of wind, solar, water, tidal, geothermal and biomass energy will reduce the energy import dependence of the European Union and it will stimulate innovation.

Nitrogen Supplying Capacity of Brown Forest Soil under Different Cropping Practices and 0.01 M CaCl2 Soluble Organic Nitrogen
17-23Views:86The best known and most remarkable example of continuous production in Hungary is the Westsik’s crop rotation experiment, which was established in 1929, and is still in use to study the effects of organic manure treatment, to develop models, and predict the likely effects of different cropping systems on soil properties and crop yields. In this respect, Westsik’s crop rotation experiment provides data of immediate value to farmers concerning the applications of green, straw and farmyard manure, as well as data sets for scientific research.
Although commonly ignored, the release of nitrogen by root and green manure crops has a significant impact on soil organic matter turnover. The design of sustainable nitrogen management strategies requires a better understanding of the processes influencing nitrogen supplying capacity, as the effects of soil organic matter on soil productivity and crop yield are still very uncertain and require further research. In the treatments of Westsik’s crop rotation experiment, nutrients removed from soil through plant growth and harvesting are replaced either by fertilisers and/or organic manure. Data can be used to study the nitrogen supplying capacity of soil under different cropping systems and its effect on the 0.01 M CaCl2 soluble organic nitrogen content of soil.
The aim of this paper is to present data on the nitrogen supplying capacity of brown forest soil from Westsik’s crop rotation experiment and to study its correlation with hundredth molar calcium-chloride soluble organic nitrogen. The main objective is to determine the effects of root and green manure crops on the nitrogen supplying capacity of soil under different cropping systems. The nitrogen supplying capacity was calculated as a difference of plant uptake, organic manure and fertiliser supply.
The 0.01 M CaCl2 soluble organic nitrogen test has proved reliable for determining the nitrogen supplying capacity of soils. Brown forest soils are low in organic matter and in the F-1 fallow-rye-potato rotation, the nitrogen supplying capacity was 15.6 kg/ha/year. 0.01 M CaCl2 soluble organic nitrogen content was as low as 1.73 mg/kg soil. Roots and green manure increased the nitrogen supplying capacity of soil by more than 100%. This increase is caused by lupine, a legumes crop, which is very well adapted to the acidic soil conditions of the Nyírség region, and cultivated as a green or root manure crop to increase soil fertility. -
Renewables in higher education
151-154Views:134Unfortunately Hungary is not too rich in natural resources, so particularly important the materials and energy-saving technologies, waste recovery, increasing the share of renewable energy. It is a complex ecological strategy which priorities of the Hungarian education and calls on the student’s attention to ecological issues, pollution and the environmental load and look for specific opportunities for the realization of sustainable development. I consider, in addition to the specific operating continuously reduce costs of the campuses we should integrate the practical experience in to engineering education.

Environment-friendly nutrient supply in the area of NYÍRERDŐ Zrt
111-116Views:112The widespread realization of environmental friendly management is an important segment of seeking sustainable technological and
technical solutions. The methods ensuring sustainable development by exploiting natural facilities have great significance. Bacteria-based
biofertilizers and wood ash are good examples of them. Using bacteria-based biofertilizer means a kind of biofertilization that is using the
possibilities provided by the ecosystem. -
Soil – Environment – Sustainability
331-337Views:179The future and life quality of human society depends primarily on the success of the sustainable use of natural resources: the geological strata–soil–water–biota–near surface atmosphere continuum. Soil is the most significant conditionally renewable natural resource in our Earth’s system, with three unique properties: multifunctionality; fertility/ productivity; resilience. In the case of rational land use and precise soil management soil does not disappear, and its desirable „quality” does not decrease considerably, irreversibly and unavoidably. Its renewal, however, requires continuous care and permanent activities.
Consequently, the prevention, elimination or moderation of soil degradation processes and extreme hydrological situations (the two main factors limiting desirable soil multifunctionality) with rational land use and soil management are the key factors and priority tasks of sustainable development on each level and in each phase of the decisionmaking process. -
Food problem and its solution
19-23Views:111The Globalization processes substantially changed relations between countries. One of main factors of these processes is forming in ХХ century of Worldwide auction organization, which activity provided with swift growth of volumes in trade of food commodities. Thus, the solution for global food problem was found. At the end of the second half of ХХ century the production volumes of agrarian goods in countries with a different level of economic development grew considerably. However, a food crisis 2007–2008 led to the necessity to define factors, which would allow to grow production, converting an agrarian sector into sustainable growing industry, passing ahead the increase of quantity of population. -
Energy Use of Biomass
264-272Views:80In this study, energy utilization of biomass is introduced with a short description of renewable energy sources and utilization possibilities of biomass.
Presently, the necessity of renewable energy sources is increasingly obvious. Among renewables, energy from biomass is to be highlighted, since this allows versatile, cheap utilization of the sun’s energy. In this respect, Hungary has advantages. Direct heat utilization and biogas production are available procedures today, whereas biodiesel and bioethanol are expected to spread in the near future. Biogas production is possibly the most versatile method for biomass conversion: it can produce energy from materials inapplicable for other utilization; at the same time, it is capable of neutralizing harmful wastes; in the end, it produces also valuable fermentative products, from bio-manure useful in agriculture, to pharmaceutical raw materials. -
Deproteinized plant juice as part of circular economy: A short review and brief experimental data
23-26Views:1485As the population of the Earth is constantly growing it generates an unmet demand for protein, which is an urgent problem. The protein extraction process is a potential solution, which offers high-quality plant protein suitable for animal and human nutrition at a favorable price. The process used within our project produces green juice from the green alfalfa biomass through pressing. After the coagulation of protein from this green juice, the by-product is called DPJ (Deproteinized Plant Juices) or brown juice. Our preliminary results match the international literature, namely that brown juice take up as much as 50% of the fresh biomass in weight. To utilize this by-product is a crucial part of the process to make it environmental-friendly and financially viable as well. The examined brown juice samples came from a small-scale experiment of alfalfa varieties carried out in the experimental farm at the University of Debrecen. According to our preliminary results, brown juice has high macro- and micronutrient values, furthermore, it has a potentially high amount of antioxidant compounds. The study highlights that brown juice is suitable as an ingredient in microbiological media, in plant nutrition as a supplementary solution, for feedstock and for preparing human food supplements or functional foods. The potential utilization of all biorefinery products makes it a very appropriate technology for today’s challenges.

Optimized balance between crop productivity, restoration and maintenance of vital soil functions and soil carbon sequestration and storage – the SmartSOIL (FP7) project
213-215Views:93Soils provide the most indispensable function of supporting the production of food and feed for a growing human population. At the same time they provide a range of regulating and supporting functions related to climate change and removal of greenhouse gases. The majority of the soil functions are closely linked to the flows and stocks of soil organic carbon (SOC); low levels of both flows and stocks may seriously interfere with several of the essential soil functions and thus affect the ecosystem services that soils deliver. Soil degradation is considered a serious problem in Europe and a large part of the degradation is caused by intensive cultivation practices in agriculture. The aim of the SmartSOIL project is to link the results of different scientific fields through a holistic and multidisciplinary approach and as a result develop a decision making tool contributing to sustainable development.

The impact of employment and income circumstances on the development of regions
15-19Views:161The economic condition of an area is fundamentally determined by the extent of employement, as well as the size and composition of its active population. No sustainable economic growth is possible without the necessary amount of employees with the proper skills.
As regards the proportion of employees, i.e. economically active people is significanlty lower in Hungary than not only in Western Europe, but also countries which joined the EU recently. One of the reasons for this fact is the low amount of part-time employment and the other is the phenomenon that the number of agricultural employees – who had a significant role – greatly decreased in the county.
The employment level of the population in the county is nearly identical as that of the North Great Plain region and it is lower than the country average. The activity proportion, i.e. the joint proportion of employees and unemployed people in the population between 15–74 years of age is 3 percentages lower than the country average. The proportion of unemployed people greatly varies depending on the small regions of the county. The proportion of registered unemployed people in the population of active age is the lowest in Debrecen and the highest in the Hajdúhadház small region. The unemployment of career-starters is a further problem to deal with.
The composition of employees in the county is different than the country average. When compared in terms of different economic sectors, it can be observed that agriculture, game management, forestry and fishery are more significant than the country average. Of the provider sectors, the proportion of financial activity, real estate matters and economic services is lower, while that of accommodation services and hospitality is higher than the country average.
There are regional differences similar to unemployment in terms of the income size which is the basis of personal income tax per taxpayer.
The income level in the North Great Plain region is lower than the country average mainly in terms of income paid for work, where this difference is 23%, while it is only 5% in the case of social income. Altogether, the income and expenditure data of the North Great Plain region are not favourable. -
Hungary’s correspondence with the EU regulations regarding liquid bio fuels
119-128Views:72During the recent years researchers from different countries have found that our environment is at risk. It has been recognised by the leaders of the member countries and they have made decisions together concerning environmental protection in several agreements, contracts. Unfortunately, these decisions have been weakened and adumbrated on numerous occasions by certain interests.
However, the energetic exploitation of the biomass has been supported by the economic and social changes of the previous years, more specifically, that of the bio fuels. The significant increase in the price of the traditional energy sources, the import dependency of the countries, the foreseeable exhaustion of the resources, the changes occurred due to joining the EU are all such problems that facilitates the application of bio fuels, as a good solution.
Our country decided to modify the then existed bio fuel component rate of 2% to 5.75% which has to be achieved by 2010. Since then, in March 2007 it has been expanded to 10% until 2020 (concerning energy content). This decision was taken knowing that this year (2006) the bio fuel rate has been 0.5%. However, the rate of 2% has not been achieved even in the EU. One can understand that the implementation cannot be fulfilled without significant political decisions and support. The main reason for this is that the price of bio fuels is not competitive with the present fossil-origin energy prices in Hungary. So in 2007 several regulations were modified. The most important one is perhaps the regulation of the revenue tax, which caused the successful tax-differentiation concerning bio fuels in more member states between 2007 and 2008. Its essence is that the revenue tax is not decreased, but if the fuel does not contain a bio fuel component of 4.4 bulking percentage per litre, „punishment” tax has to be paid. Moreover, on behalf of the implementation, regulations concerning bio fuels and bio fuel components are improving
At present the production and the application of bio fuels without any support are not economical yet. That is why it is important to emphasize the support policy of our country. After joining the Union, the new members can receive some shares from the direct disbursements, but only a tan increasing rate, we can achieve the 100% in 2013, though there is an opportunity for national contribution. Energy plants produced in agriculture receive separate supplementary support which is an advantageous opportunity for the farmers of the sector. Bio fuels cannot only be supported through agriculture, of course, but by research development, investment etc.
All in all, it can be concluded that Hungary seeks to fulfil the EU responsibilities taken and by this, to contribute to the maintenance of the sustainable progress, decrease of environmental pollution and the import dependency of energy sources. -
The importance of predator species in the population dynamics of the Brown hares (Lepus europaeus, Pallas 1778) – Literature review
43-49Views:181One of the conditions for successful small game management is the good management of predator species. The predator species play an important role in the sustainable utilization of the domestic brown hare populations. A portion of these species are under nature protection and with the rest of the species can be utilizing by the wildlife management professionals. Important prey species of brown hares: perspective are red fox, domestic dog and domestic cat. Based on latest date of the National Game Management Database in hunting bags increasing every year the number of the European badger, the stone marten and the golden jackal. In Hungary the brown hare’s most important predator bird species are common buzzard, marsh-harries and goshawk. The human race is not only as a top predator affects the number of the population of brown hares with the wildlife management but indirectly with traffic, (soil cultivation, mowing, and pest control) as well. The control of predators is absolutely necessary for successful small game management, but without sufficient habitat size and habitat development it is hardly sufficient.

Case study based analyses of economic viability of Hungarian beef farms
184-193Views:73Our country has great traditions in the field of beef production. As early as the Middle Ages, Hungary was known as Europe’s beef exporter. In this decade, production of the Hungarian Grey has increased, due to the popular method of keeping these animals extensively. These animals were even exported to the European markets on foot.
After joining the European Union, this sector of agriculture has been receiving attention due to the major subsidies which were given. Accordingly, numerous farmers have tried to enter this sector of production. However, the power relations have been changed lately, as have the technology used in production, which has undergone several developments. The integrative connections in the sector had been split and also the size of optimal and sustainable production has arisen.
The economic activities must be judged by their effectiveness and profitability, but in most cases their effectiveness can only be seen through such outstanding facts which are independent from the farmer.
I would like to model the economy of a certain enterprise, and the size and the level of its production, through my research under the actual economic circumstances. In my research, I pay special attention to the circumstances which are important in the Hungarian agricultural sector and rural development.
