The Aalborg process and its Hungarian connections
Published May 23, 2006
5-14

The four European Conferences on Sustainable Cities and Towns gave birth to documents that are important from the point of view of local sustainability. These are, in chronological order, the Aalborg Charter – 1994 Aalborg, the Lisbon Action Plan – 1996 Lisbon, the Hannover Call – 2000 Hannover, and the Aalborg Commitments – 2004 Aalbor...g. Throughout the process, the emphasis gradually moved from planning to the implementation of plans.
Today, there are more than 2000 signatories of the Aalborg

Charter. The cutting edge of the process are Italy and Spain, the municipalities of these two countries add up to 80 per cent of all signatories. In both countries, the national commitment is given, but there is not a body that could coordinate the activities related to sustainability, so local governments play the major role in it. The constitutions of these two countries also pass on some duties that are relevant from the point of view of sustainability within the competence of local governments, and allow resources to implement them. In the case of the United Kingdom, the commitment of the national government, and especially the Prime Minister, is the major factor in the movement towards local sustainability.
The former socialist countries in Europe, as well as Hungary are relatively underdeveloped economically, so the social and environmental pillars of sustainable development are pushed into the background behind the economical pillar. As a result of the lack of national commitment, there is no guidance and there are no case studies available, so only a small part of local governments are informed of this important international movement, and so are committed to it. The lack of resources is also a problem. The consequence of all this is that there are 35 municipalities from the Eastern European countries that joined the EU in 2004, and only four from Hungary – to mention by name Aba, Kecskemét, Monor and Nagykanizsa – that signed the Aalborg Charter.

The institutional background of local sustainability strategies
Published July 28, 2008
7-13

The system of local sustainability strategies is shaped by the intentions of the central government and local initiatives together. From the aspect of the hierarchy of government organization in Hungary it means that there are institutions on the central government’s side – different ministries or other governmental institutions – the rol...e of which is mainly coordination; and local governments (regional and local as well) also form their institutions at the municipality.
It is important to examine the institutional background, as in Hungary the formation of sustainability policy is still in its infancy, so it is well worth taking the institutional background of countries the circumstances of which are similar to ours and have successful sustainability policies as a basis. In this presentation I will examine whether the top-down or the bottom-up approach is chosen, which institution is in charge of the process, what the legal background is like, and what sources are available for use in these countries.

Inhibitive factors of the Local Agenda process in Hungary
Published July 16, 2007
151-157

The concept of sustainable development is one of the most fashionable concepts in the world nowadays, but Hungary – 15 years after the Rio conference – is still far behind the times: it is the only country in the EU 25 that has not prepared a national sustainable development strategy.
The situation is not encouraging in the field of loca...l sustainability either. Although there are initiatives that can be described as ones that were prepared in the spirit of local sustainable development, no municipalities have working, formulated sustainability strategies.
One of the most important messages of sustainability is that the consultative process between the local government and the community can have far reaching consequences, which can influence the municipality’s life for a long time. In my paper, I explore the inhibitive factors bearing this duality in mind, as the lack of top-down initiatives together with the low number and the low support of bottom-up approaches have led to this image which is not too flattering for Hungary. I also aim to show, through the example of other countries, how these inhibitive factors can be reduced.

The use of MFA indicators in the characterization of the settlement sustainability
Published September 2, 2009
107-116

One of the key sustainability challenges for the coming decades will be to improve the management of natural resources in order to reduce current levels of anthropogenic environmental pressure and respect the biological and physical limits and the carrying capacity of the planet. The first step towards meeting this challenge is an enhancement o...f the understanding of the material basis of our society. In the past 15 years, scientists in several research institutes have created a fast growing field of research, a new family of different methods, named material flow analysis (MFA). These instruments have an increasing policy relevance: international organizations (UN, EU, OECD) have encouraged member states to establish MFA accounting in their statistical programmes and urged governments and economic actors to use these tools. In this paper I present selected examples to reveal how the MFA approach and derived material flow indicators can be used for the evaluation of sustainability policies at municipality level.

The ain impacts of the Lisbon Strategy on tobacco growing
Published May 23, 2006
80-87

The Lisbon Strategy of the EU promises a more competitive Europe with more and better workplaces, in addition to sustainability.
Tobacco production is one of the most controversial industries of the agricultural sphere in the European Union. This crop is a „leader” of the world’s economic growth, a promoter of globalisation and has bee...n an economic channel between America and Europe for more than 500 years. It is also a motor of technical development, due to its inducing effect on profitability and work efficiency. The tax competition of the states and the increase in consumption have become such a self-inducing system in which the increase of production created an increasing number of jobs, especially in tobacco growing, where the replacement of manual labour was much slower than the increase of the demand for raw material. The fact that smoking is becoming general should be handled as a social demand, though its health risks cannot be denied. However, the extreme objection to smoking cannot be accepted, especially not when it evokes social strains and concludes that people smoke because of tobacco production, al though the real situation is the opposite: People smoke in Europe, so the tobacco should be grown here, as is in our economic interest.
There is a contradiction between the strategic objectives and the roles of the industry which should be ceased urgently. Al thong aim is the creation of jobs, stopping tobacco growing could result in unexpected agro-social disadvantages. Rejection of the industry’s sustainability questions the realization of the keystones of the strategy. Competitiveness, sustainability and social cohesion should be implemented as a unit of the strategy also in tobacco growing.

41-44

UN Conference on Environment and Development óta (1992 Rio de Janeiro) a sustainable development fogalma bevonult a nemzetközi szervezetek és a nemzeti kormányok programjaiba. A fenntartható fejlődés megvalósítására sok országban stratégiákat dolgoztak ki. Magyarországon ilyen stratégiai a dokumentum ma még nincs, de valószín...ű, hogy rövidesen elkészül. A szerző ehhez az előkészítő folyamathoz kíván hozzájárulni javaslataival. A fenntarthatóság (sustainability) megvalósításához hosszú időre és konkrét cselekvési programok összefüggő láncolatára van szükség. A szerző javaslatai szerint a következő 3-5 évben tíz prioritást célszerű támogatni a kormány és a civil társadalom részéről:
1. Környezetvédelem
2. Környezeti nevelés és tudatformálás
3. A szemét, a hulladék eltávolítása és hasznosítása

Interpretation of sustainability in the utilization of renewable energy sources
Published November 20, 2011
61-64

The utilization of renewable energy sources (res) is crucial regarding to sustainable reconstruction of energy systems. The target is a balanced, sustainable development of Hungarian energy management considering equally the ecological, social and economic aspects. There are many different technologies of utilization of res varied by sources, c...onversion processes, size and products. The comparison of each technology and their sustainability assessment are required by the importance of efficient remodeling of energy infrastructure. The group of attributes was composed by numerous important parameters in the course of our analysis with the choice experiment (ce) methodology. The estimation of each attributes’ influence on the individual’s preferences and choices was possible by this method and the preferences of the statistical population was concluded. So thus the utility derived from each attribute was estimated. The result of the ce analysis for the population of experts is demonstrated in the current phase of our research.

Role of living bacteria and other amendment in early development of maize
Published April 23, 2014
53-56

Different 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.

39-46

Hungary’s new national sustainable development strategy is expected to be drawn up by 2012 and social debate for discussion has already been under way. This document provides the basis of all other strategies, programs and plans. I prepared a survey by the method of structured in-depth interviews to explore the opinion of experts engaged in e...nvironmental issues and strategy development about sustainable development, the situation of the Hungarian strategy adopted in 2007 and applied indicators. The picture is highly diverse: there is a lack of unified viewpoint even about the concept of sustainability. However, the definition of a common, jointly adopted concept is the first stage in strategy development. Precisely formulated objectives and their related indicators are required for a strategy to fulfill its role – this is the theoretical part of strategic thinking.

Soil Fertility Management in Westsik’s Crop Rotation Experiment
Published December 4, 2001
34-39

The crop rotation experiment, established by Vilmos Westsik in 1929, is the best known and most remarkable example of continuous production in Hungary. It is still used to study the effects of organic manure treatment, develop models and predict the likely effects of different cropping systems on soil properties and crop yields. Westsik’s cro...p rotation experiment provides data of immediate value to farmers concerning the applications of fertilisers, green, straw and farmyard manure. The experiment also provides a resource of yield, plant and soil data sets for scientific research into the soil and plant processes which control soil fertility, and into the sustainability of production without environmental deterioration. The maintenance of Westsik’s crop rotation experiment can be used to illustrate the value of long-term field experiments.

The Role and Significance of Soil Analyses in Plant Nutrition and Environmental Protection
Published March 4, 2006
3-8

Hungary 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 pas...t 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.

close relation. This means that policies related to the economy and the environment cannot be handled without each other. The United Nations Conference (Stockholm, 1972) was the first global conference to signal that environment concerns have increasingly become subject of mainstream socio-economic policies. The process started in the Seventies..., laying emphasis on environment protection, plays an important role in the policy of international agencies. The use of environmental indicators is essential for monitoring the effects of environmental measures. The best way of evaluating sustainability if the results can be compared on a global level. International efforts are being made by the United Nations (UN), the Organisation for Economic Co-operation and Development (OECD), the Statistical Office of the European Commission (Eurostat) and other international agencies to develop a framework for environment statistics. This study deals with these frameworks, paying attention to agri-environment indicators. Hungary became a member of the UN in 1955, of the OECD in 1996, and will become a member of the European Union in 2004. The first summary in connection with environmental indicators of Hungary, taking the OECD Pressure – State – Response framework as a basis, was published in 1994. As a result, comparability of environmental indicators for Hungary with those used international are given.

Soil – Environment – Sustainability
Published November 13, 2012
331-337

The 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: multifunctionali...ty; 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.

Baking quality of winter wheat (Triticum aestivum L.) in the long-term experiments on chernozem soil
Published October 5, 2010
152-156

Agriculture has traditionally an important role in Hungarian economy and rural development. About 75 % of Hungary’s total territory
is under agricultural land use. Because of ecological conditions and production traditions cereals (wheat, maize etc) have the greatest
importance in Hungarian crop production. In the 1980’s the country-a...verage yields of wheat were about 5,0-5,5 t ha-1 („industrial-like”
crop production-model). In the 1990’s the yields of wheat dropped to 4,0 t ha-1 because of low input-using and wide application of the issues
of environmental protection and sustainability. Winter wheat production for quality has a decisive role in certain regions of Hungary
(eastern and middle-parts).
The quality of wheat is complex and different. Three major growing factor groups determine the quality of winter wheat: genotype,
agroecological conditions and agrotechnical factors. In wheat production for quality the selection of the variety is the most important
element. Our long-term experiments proved that the quality traits of a variety means the highest (maximum) limit of quality which could not
be exceeded in fact. During the vegetation period of wheat the different ecological and agrotechnical factors could help or on the contrary
could demage the quality parameters of wheat.
The agrotechnical factors determining the baking quality of wheat can be divided into two groups: the first group means the factors with
direct effects on quality (fertilization, irrigation, harvest); the second group contains the elements with indirect effects on quality (crop
rotation, tillage, planting, crop protection).
Appropriate fertilization could help to manifest the maximum of quality parameters of a wheat genotype and could reduce the qualityfluctuation
in unfavourable ecological and agrotechnical conditions.

Tourism and sustainability in Hungary
Published July 28, 2008
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.

Insect base-protein: A new opportunity in animal nutrition
Published May 20, 2020
129-138

The consumption of insect protein, as well as its use in animal feeding, has become a trend. This trend is particularly receiving a lot of attention in animal nutrition because the current protein source of the highest quality in animal feeding which is fishmeal is unsustainable, expensive and its demand is higher than supply. Insect protei...n can be of great potential in combating world hunger as the world population continues to increase. The potential of insect protein is wide-ranging, it could improve the economics of feed production, lead to cleaner production due to its low environmental footprint.

This review focuses on the need, (nutritional and environmental) advantages of insect protein in feed production, as well as previous research findings.

The unanimous conclusion of the reviewed papers is that insect protein has a great potential in feed production in terms of nutritional value, environmental implication, sustainability as well as economic implication.

However, there is a need for the intensification of research on this alternative protein source in Europe, especially in aquaculture due to the approval of 7 insect species in aquafeeds by the European Union. Another reason for the intensification is that there is still much to be done as a result of past research which shows that growth effects vary based on species and inclusion level.

Comparison of Pálfai’s drought index and the Normalised Precipitation Index in the North Great Plain region
Published February 17, 2015
59-64

Agriculture has always been an important role in economy, food supplies, sustainability of society and creation of job opportunities in Hungary. Our country has resource-related strength of agriculture, because we have more than 4.5 million ha for agricultural production. Agricultural production can be influenced by several factors, including c...limate, hydrology, soil conditions and antropogenic impacts. Climate determines the quality and quantity of the crop yields. The climate conditions in Hungary are variable and it shows spatial and temporal extremes. As a result of this, drought have become more frequent in our country (2003, 2007, 2009, 2012), which is reflected in the decline in yields as well. In the present study, Pálfai's Drought Index (PAI) and the Standardized Precipitation Index (SPI) were compared 2003–2012 in Debrecen. The temperature and precipitation data were calculated from data provided by a local meteorological station to work out PAI, while the SPI-3 index values were downloaded from the database of the European Drought Observatory. This allowed to drought assessment in a local and regional scale. Our study was supplemented with SPI-3, soil moisture anomalies, PAI and yields of wheat (Triticum aestivum L.) and maize (Zea mays L.) to evaluating the impact of drought on agriculture.
