    The global energy consumption is continuously growing, because the population of Earth and the standard of living expands day by day. As a result, the emission of greenhouse gases increases further more. The various countries use the different types of fuels in varying amount.In this study we have examined the primary energy consumption of the countries, according to the BP Statistical Review of World Energy June 2016 (BP, 2016), based upon their usage of fuels.The assay resulted in a 7 cluster model. With one exception, each cluster contains a resource, which is used in a much larger amount than in the other clusters. As a result, we may differentiate between an average cluster, and the clusters of countries that use primarily hydropower, nuclear energy, renewable energy, coal, fossil oil, and natural gas.We have examined if there is any connection between the location of a country in a cluster and its HDI, as well as the countries’ competitiveness.

    Poultry is highly ranked in theWorld meat production and consumption (it accounted for 32% in 2007), and, in the past 20 years it was growing with an annual rate of 3–6%, higher than in case of any other meat-types. This tendency is also valid for Hungary: poultry has the largest share (29.8 kg/person/year, 47%) in the domestic meat consumption since 2000, which is among the EU top (KSH, 2007). As the result of the animal health and nutrition scandals, the EU animal welfare and quality requirements and the advancements in health consciousness the Master-Good group launched the production, processing and trade of free-range poultry under the brand “Free-range chicken”. The new products had good consumer responses, because at present 1.5% of the processed chicken in Hungary (25 tons/week) is under this brand. As it regards the future of this product, we can expect the decrease of the current 1.5 times higher production price over broiler chicken, due to the increasing energy, labour and other cost items, thus the increase of the domestic consumption by 25–30% per annum can be foreseen. Besides the growth in domestic demand, increasing foreign consumer demand can also be expected because of the space requirement of the production. Summarising the above mentioned: „Free range chicken” can be one of the most successful products of the Hungarian poultry industry. In order to realise the prognosis mentioned above, it is inevitable to learn the consumer attitudes towards the brand. A primary market research programme supported by the Master Good group has been launched to study the main features of the domestic chicken meat consumption – including the „Free-range chicken” as highlighted brand. The primary aim of the research was the complete assessment and evaluation of the Hungarian chicken consumption habits and the identification of the possible take-off points. The research undertaken resulted basic information concerning the internal structure of the Hungarian poultry consumption (including that of the „Free-range chicken”), the potential consumer groups and their requirements, provided information on the consumers’knowledge of the products and identified the elements of the consumers’ judgements. This will serve as basis for a marketing communication programme to increase the domestic „Free-range chicken” consumption.

    The aim of the paper was to determine the influence of the fertilization level on the energy and economics efficiency of the production technologies of selected crops processed into bioethanol or biogas. There were investigated the following crops: rye, triticale, wheat, sugar beets, maize, sorghum, reed canarygrass and Virginia fanpetals. In the energetic efficiency the Energy Return on Energy Investment index (EroEI) was used. Apart from the ERoEI ratio, the Net Energy Value (NEV) ratio was also used. In the economics efficiency attitude, the Gross Margin (GM) was determined.The investigations proved that in general, the production technologies of crops where the lowest levels of nitrogen fertilization were applied proved to have the highest energetic efficiency. The highest economic efficiency was characterized by the production of corn for biogas. In the case of the production of bioethanol (all plants), ratios were on the verge of profitability or the lack of it showed.The analysis proved that the efficiency of the technologies of production of the crops to be processed into biogas is several times higher than the energetic efficiency of the technologies of production of the crops to be processed into bioethanol.

    The problem of nutrition security is getting worse in Africa, due to increasing population growth and poor progress in efforts directed at reducing food insecurity in many countries in the continent. The paper undertook an assessment of the food security situation and food consumption pattern in rural households in Ogun state, Nigeria. A multistage sampling technique was used to select 260 rural households from whom data were collected through structured questionnaire. The tools of analysis were descriptive statistics and food security index. The former described the consumption pattern, and households’ sources of food availability, while the latter was used to analyse the food security situation. The result of the rural households’ consumption pattern reveals that the rural households derived more of their energy from carbohydrates at the expense of other classes of food items. The result also shows that majority (75.5%) obtained their food through their own production and supplemented same with food purchased from the market to meet up with their family needs. Based on the recommended daily calorie intake (R) of 2,470 kcal, 59.6% of the rural households were food insecure while 40.4% were food secure. The calculated head count ratio (H) for the food insecure households was 0.6, confirming that almost 60% of households in the study area were food insecure. For secure households, the head count ratio (H) was 0.4, further confirming that only about 40% of households in the study area were food secure. The shortfall index and surplus index were 0.2787 and 0.3498 respectively, meaning that the energy requirement was less by about 27 percent and in excess of 34 percent for the food insecure and food secure households. The paper recommends that while enhancing production of arable crops - roots, tubers and cereals, a sensible balance of tilting towards meeting the requirements in the consumption of animal protein/legume, fats/oils, fruits and vegetables must be maintained to ensure food security. This policy thrust could be enhanced through mass education.

  • Using sustainable development tools for solving property rights in Montenegro

    In recent months Montenegro has been faced with serious budget problems , one proposed solution of which has been to reduce the number of employees in state administration. Additionally, the costs of living are above the disposable budget of most households, in particular the high cost of electricity. While the government warns about a lack of electricity, the citizens are hardly in the position to cover these costs. Montenegro is dealing with the double challenge of inefficient use of space (the country features over 100,000 illegal homes)(I don’t understand the link between inefficient use of space and illegal homes) and inefficient energy use (Montenegro needs an average of 8.5 times more energy per unit produced than an average EU country). How can these problems be solved in a way which pleases both sides? In this paper, an approach is presented which links the solving of the problem of illegal construction with increasing the level of energy efficiency in households, businesses and other facilities. There is a model developed by UNDP Montenegro – an integrated policy solution to the double challenge of providing energy efficiency measures to incentivise households to legalise their homes. The legalisation of illegal buildings by the introduction of mandatory energy efficiency measures in them may at the same time result in an increase of revenue to the central and local budgets, the reduction of negative impacts on the environment, an increase in employment, the engagement of the economy, a reduction of electricity consumption and thereby to reduce the need to import electricity, and ultimately the increased welfare of the population.

    Climate change is considered as one of the biggest challenges of XXI century and global action is needed to mitigate greenhouse gases (GHG) and adapt to changing water levels and temperatures, which affect food supply and ecosystem integrity. Climate change will have significant economic and social impacts in many regions of EU and sectors like agriculture is considered to bear greater adverse affects. Less developed regions and certain sections of society (the elderly and/or low-income households) are expected to suffer more from climate change. Climate change policy of EU, adopted in December 2008, includes ambitious targets for 2020. The policy is focused on a sustainable future with an energy-efficient economy by (i) cutting greenhouse gases by 20% (30% if international agreement is reached), (ii) reducing energy consumption by 20% through increased energy efficiency and iii) meeting 20% of energy needs from renewable sources. In the frame of the headline targets of Europe 2020 Strategy, this paper discusses most important greenhouse gas-emitting activities in agriculture, emphasizes the importance structural changes through the modernisation of infrastructure particularly in developing regions of EU and calls for enhancing the competitiveness of economy to promote energy efficiency.

    The portion of oil could be estimated 33 % of global primary energy consumption in 2012 (BP, 2012) and its average price – beside the products produced from it as well - significantly increased, unlike the demand for transport which has been reduced. This tendency is expected to remain unchanged in the long run, therefore, there is a great importance for the variety of diesel fuel distributors, in comparison of the ratio value for each of them, and replacing them with biodiesel can be used in the comparison. We executed 3 dynamometer measurements performed to determine three different dealers purchased diesel oil, some economical examinations of the diesel oil retail price, and the use of biodiesel all based on the expected economic studies in the literature studies of extra fuel consumption values. The results of these tests indicate that the differences of consumption between diesel oils can be up to 5 %, the conclusion is that distinctions of diesel oil consumptions are almost the same when we tested the differences between diesel oil and biodiesel. This means we can reach the same result with a high quality biodiesel as with poor quality diesel oil. This also means that– below 20% of mixing ratio we can easily choose by prices alone. Between these prices and products ( D1, D2, D3), we can save 4.8% diesel oil by using D2, 6.2% diesel oil by using D3 compared to D1. There could be a little revolution variance (D2: 2.9-6%, D3: 4.9- 7.1%), but this variance is under 1% so it is negligible.

  • Water footprint in Hungary

    More and more news report on water-related extreme environmental phenomena. Some of these are natural, which are often beyond the human race. But others are definitely due to anthropogenic effects. I think the water footprint index is able to highlight national and international water-use processes and gives us the opportunity of organizing a sustainable, consumer-, environmental- and governancefriendly management. 81% of the fresh water withdrawal is from surface water bodies in the EU. In Europe as a whole, 44% of abstraction is used for energy production, 24% for agriculture, 21% for public water supply and 11% for industry. Public water supply is confined to ground waters. To the water resources related human activity caused qualitative and quantitative amortisation will grow worse in the foreseeable future due to the climate change. Beside seasonal differences the sectoral differences are increasingly becoming critical between different areas, such as Southern and Western Europe. The former, wrong agricultural support system has worsened the situation since it gave financial aid for the used improper techniques of water-intensive crop cultivation. By today, this seems to be solved. Public water abstraction is affected by many factors, of which mostly are based on social situation and habits, but technological leakage receives a big role as well. Interesting, that for example the residents’water consumption in Eastern Europe decreased because price were raised and regular measurements were introduced. But in Southern Europe it increased due to tourism in the past period. Industrial water withdrawal decreased across Europe because of the decline of industry and the development of technologies. According to the European Environment Agency (EEA), the Union needs a sustainable, demand-driven leadership which focuses on the preservation and use efficiency. This have already appeared in politics and legal administration as well. Current research calls the attention to the significance and difficulties of this kind of domestic estimation presented trough the water footprint calculation of bread and pork in Hungary. The received data indicate the domestic water consumption trends in a modern approach. There is no doubt for me about the urgent necessity of water footprint calculation because as a result innovative, sustainability supported environmental, social, economical, and political relationships can be created – not just on local, regional or national level, but on interregional, European and even global stage.

    Consumer lifestyle and health are relevant factors to understanding consumption preferences.The number of lifestyle diseases has dramatically increased worldwide. The main cause for these diseases is the change in lifestyle; including a lack of attention to physical activity and good nutrition. Health and lifestyle are important factors by purchase decision process. In accordance with these, I examine the consumer behaviour toward soft drinks with special regards to healthy lifestyle and the state of health. My examinations can be considered mainly as a qualitative research among German students, which can serve as a basis for further analyses and research, however, the conclusions and experience gained from it are worthy of consideration. I differentiated five categories: ice tea, carbonated soft drinks, fruit juices, mineral waters, sport and energy drinks and studied the consumer behaviour toward them. The study focuses on the consumption of these and the factors influencing their purchase with special regards to lifestyle.

    Food production and supply has been on the decline in Nigeria with a consequent impact on household food security. This study examined the influence of urban farming on household food security in Oyo State, Nigeria. Multi-stage sampling procedure was used to select 159 farm households in a cross-sectional survey. Structured questionnaire was used to obtain data on socio-economic characteristics, determine the food security status of urban crop farming households in the study area, and examine the effects of urban crop production on households’ food security status. Data were analysed using descriptive statistics while the statistical tools were Food Security Index (FSI) and Probit Regression Model (PRM). Results revealed that 84.9% of the respondents was male, 81.2% married. The average age, household size, and farm size were 49.6 years, 6 persons, 1.1 hectares respectively. Most (75.5%) of the respondents did not have access to consumption credit and 62.3% did not belong to any farmers association. Based on minimum daily energy requirement per adult equivalent of N230.8, 90.6% of the farm households was food secure.

    The PRM showed that age (β = -0.1, p<0.05), household size (β= -0.4, p<0.01) and economic efficiency (β = -61.6, p<0.05) reduced the probability of household food security while access to consumption credit (β= 1.7, p<0.05) and allocative efficiency (β = 67.9, p<0.05) increased the probability of household food security. The study concluded that urban farming significantly influence household food security.

    Renewable technologies and the extension of their scope of usage basically has to face the general obstacles like any other novelties newly introduced to the market. In the case of environmentally friendly and clean technologies we must consider another critical aspect: the knowledge and the trust of the potential future users. To influence these people first we must extend their knowledge regarding renewable energies so they will be able to change their own approach about them. Usually the most crucial factor is the economic efficiency which determines the attitude of the majority of the users. Even the ones whose decision making process is highly based on the environmental patterns. In the case of any technology, the economic aspect is significantly influenced by its operational effectiveness. So this analysis – besides the direct economic matters – aims to examine how the performance of thermal water heating in greenhouses can be improved by using heat pumping.

    The Dutch greenhouse horticulture industry is characterized by world leadership in high-tech innovation. The dynamics of this playing field are innovation in production systems and automation, reduction in energy consumption and sharing limited space. However, international competitive advantage of the industry is under pressure and sustainable growth of individual enterprises is no longer a certainty. The sector’s ambition is to innovate better and grow faster than the competition in the rest of the world. Realizing this ambition requires strengthening the knowledge base, stimulating entrepreneurship, innovation (not just technological, but especially business process innovation). It also requires educating and professionalizing people. However, knowledge transfer in this industry is often fragmented and innovation through horizontal and vertical collaboration throughout the value chain is limited. This paper focuses on the question: how can the grower and the supplier in the greenhouse horticulture chain gain competitive advantage through radical product and process innovation. The challenge lies in time- to-market, in customer relationship, in developing new product/market combinations and in innovative entrepreneurship. In this paper an innovation and entrepreneurial educational and research programme is introduced. The programme aims at strengthening multidisciplinary collaboration between enterprise, education and research. Using best practice examples, the paper illustrates how companies can realize growth and improve the innovative capacity of the organization as well as the individual by linking economic and social sustainability. The paper continues to show how participants of the program develop competencies by means of going through a learning cycle of single-loop, double-loop and triple loop learning: reduction of mistakes, change towards new concepts and improvement of the ability to learn. Finally, the paper illustrates the importance of combining enterprise, education and research in regional networks, with examples from the greenhouse horticulture sector. These networks generate economic growth and international competitiveness by acting as business accelerators.
