EVALUATING THE VARIATIONS IN THE FLOOD SUSCEPTIBILITY MAPS ACCURACIES DUE TO THE ALTERATIONS IN THE TYPE AND EXTENT OF THE FLOOD INVENTORY
Authors: Tehrany M. Sh. , Jones S.
Published: October 2017

Abstract. This paper explores the influence of the extent and density of the inventory data on the final outcomes. This study aimed to examine the impact of different formats and extents of the flood inventory data on the final susceptibility map. An extreme 2011 Brisbane flood event was used as the case study. LR model was applied using polygon and point formats of the inventory data. Random points of 1000, 700, 500, 300, 100 and 50 were selected and susceptibility mapping was undertaken using each group of random points. To perform the modelling Logistic Regression (LR) method was selected as it is a very well-known algorithm in natural hazard modelling due to its easily understandable, rapid processing time and accurate measurement approach. The resultant maps were assessed visually and statistically using Area under Curve (AUC) method. The prediction rates measured for susceptibility maps produced by polygon, 1000, 700, 500, 300, 100 and 50 random points were 63 %, 76 %, 88 %, 80 %, 74 %, 71 % and 65 % respectively. Evidently, using the polygon format of the inventory data didn’t lead to the reasonable outcomes. In the case of random points, raising the number of points consequently increased the prediction rates, except for 1000 points. Hence, the minimum and maximum thresholds for the extent of the inventory must be set prior to the analysis. It is concluded that the extent and format of the inventory data are also two of the influential components in the precision of the modelling.

Published: October 2017

Abstract. The central dry zone area of Myanmar is the most water stressed and also one of the most food insecure regions in the country. In the Dry Zone area, the total population is 10.1 million people in 54 townships, in which approximately 43 % live in below poverty line and 40–50 % of the rural population is landless. Agriculture is the most important economic sector in Myanmar as it is essential for national food security and a major source of livelihood for its people. In this region the adverse effects of climate change such as late or early onset of monsoon season, longer dry spells, erratic rainfall, increasing temperature, heavy rains, stronger typhoons, extreme spatial-temporal variability of rainfall, high intensities, limited rainfall events in the growing season, heat stress, drought, flooding, sea water intrusion, land degradation, desertification, deforestation and other natural disasters are believed to be a major constraint to food insecurity. For food vulnerability, we use following indicators: slope, precipitation, vegetation, soil, erosion, land degradation and harvest failure in ArcGIS software. The erosion is influenced by rainfall and slope, while land degradation is directly related to vegetation, drainage and soil. While harvest failure can be generate by rainfall and flood potential zones. Results show that around 45 % study area comes under very high erosion danger level, 70 % under average harvest failure, 59 % intermediate land degradation area and the overall around 45 % study area comes under insecure food vulnerability zone. Our analysis shows an increase in alluvial farming by 1745.33 km2 since 1988 to reduce the insecure food vulnerability. Food vulnerability map is also relevant to increased population and low income areas. The extreme climatic events are likely increase in frequency and magnitude of serious drought periods and extreme floods. Food insecurity is an important thing that must be reviewed because it relates to the lives of many people. This paper is helpful for identifying the areas of food needs in central dry zone area of Myanmar.
A NEW SPECTRAL-SPATIAL FRAMEWORK FOR CLASSIFICATION OF HYPERSPECTRAL DATA
Authors: Akbari D.
Published: October 2017

Abstract. In this paper, an innovative framework, based on both spectral and spatial information, is proposed. The objective is to improve the classification of hyperspectral images for high resolution land cover mapping. The spatial information is obtained by a marker-based Minimum Spanning Forest (MSF) algorithm. A pixel-based SVM algorithm is first used to classify the image. Then, the marker- based MSF spectral-spatial algorithm is applied to improve the accuracy for classes with low accuracy. The marker-based MSF algorithm is used as a binary classifier. These two classes are the low accuracy class and the remaining classes. Finally, the SVM algorithm is trained for classes with acceptable accuracy. To evaluate the proposed approach, the Berlin hyperspectral dataset is tested. Experimental results demonstrate the superiority of the proposed method compared to the original MSF-based approach. It achieves approximately 5 % higher rates in kappa coefficients of agreement, in comparison to the original MSF-based method.
On soil textural classifications and soil texture-based estimations
Authors: Martín Miguel Ángel , Pachepsky Yakov A. , García-Gutiérrez Carlos , Reyes Miguel
Published: October 2017

Abstract. The soil texture representation with the standard textural fraction triplet 'sand-silt-clay' is commonly used to estimate soil properties. The objective of this work was to test the hypothesis that other fraction sizes in the triplets may provide better representation of soil texture for estimating some soil parameters. We estimated the cumulative particle size distribution and bulk density from entropy-based representation of the textural triplet with experimental data for 6300 soil samples. Results supported the hypothesis. For example, simulated distributions were not significantly different from the original ones in 25 and 85 % of cases when the 'sand-silt-sand' and 'very coarse+coarse + medium sand – fine +very fine sand – silt+clay', were used, respectively. When the same standard and modified triplets were used to estimate the average bulk density, the coefficients of determination were 0.001 and 0.967, respectively. Overall, the textural triplet selection appears to be application- and data-specific.

Published: October 2017

A mensuração do desempenho ambiental pela metodologia de Avaliação do Ciclo de Vida (ACV) possibilita a compreensão dos impactos ambientais nas etapas do processo de produção de uma edificação. Para facilitar esse processo pode ser utilizado o Building Information Modeling (BIM). Neste contexto, o presente trabalho consistiu no estudo e avaliação da aplicação do BIM na ACV de edificações a partir de um estudo de caso utilizando softwares que trabalham na plataforma BIM, o Autodesk Revit e o DesignBuilder. Foi possível estimar as emissões de CO2 na fase de pré-uso de uma edificação escolar. No entanto, notou-se problemas na questão da interoperabilidade quando o modelo é exportado do primeiro para o segundo software. A quantificação das emissões foi realizada ainda manualmente, para comparação com os resultados fornecidos pelo software. Os resultados mostraram que a quantificação de CO2 é mais precisa para sistemas construtivos homogêneos, como paredes de concreto. A principal contribuição do presente estudo foi a verificação da viabilidade do software DesignBuilder para a quantificação das emissões de CO2 no ciclo de vida das edificações, como uma ferramenta de projeto para edificações de baixo carbono. Abstract The measurement of environmental performance using Life Cycle Assessment (LCA) methodology enables comprehensive understanding of environmental impacts in all stages of the production process of a building. In order to facilitate this process can be used the Building Information Modeling (BIM). In this context, the present paper aims to study and evaluate the implementation of BIM in LCA of buildings from a case study using software that works on the BIM platform, Autodesk Revit and DesignBuilder. It was possible to estimate the CO2 emissions in the pre-use stage of a school building. However, problems have been noted in the interoperability issue when the model is exported from the first to the second software. The CO2 emission quantification was still performed manually, for comparison with the results provided by the software. The results showed that the quantification of CO2 is more accurate for homogeneous constructive systems, such as concrete walls The main contribution of the present study was the verification of the viability of the DesignBuilder software for the quantification of CO2 emissions in the life cycle of buildings, as a design tool for low carbon buildings.

Sustainability Reporting Practices: Evidence from Bangladesh
Authors: Akhter Sumaiya , Dey Pappu Kumar
Published: October 2017

The objective of this paper is to examine the nature and extent of sustainability reporting practices by the listed companies in Bangladesh. In order to fulfill this objective, the research has examined the content analysis of annual report (2015-2016) and website of the top 50 listed companies (according to market capitalization). Based on Global Reporting Initiative (GRI) G4 guidelines, the study investigates three broad areas i.e. economic, environmental and social with 40 indicators. The findings of the study demonstrate that organizations in Bangladesh address few sustainability issues. Companies focus more on community development which is 90%, followed by employment and employee benefits (67%). The level of disclosures in website is meagre where only 26% of the sample companies disclose at least one indicator. Organizations’ attention on issues like environment, human rights and product responsibility is limited in relation to other issues. The extent of disclosure is also poor that is 66% of the companies use less than 25 sentences in sustainability reporting. Moreover, only 16% of the sample companies use separate sustainability reporting section. The limited disclosures on sustainability issues may be because of voluntary sustainability reporting in Bangladesh.

In addition, the researcher also carried out semi-structured interviews so as to explore factors affecting students' attitudes towards learning EFL.Findings of the study showed that the overall mean of attitudes of public and private schools' students towards learning in EFL is positive; however, the results indicated that students of private schools have more positive attitudes towards learning EFL than students of public schools.The findings showed that methods of teaching, the physical environment and the educational setting of schools were the main factors that affected students’ attitudes towards learning EFL.
Reading First, Science Last: An Investigation into Reading Comprehension Strategy Usage in Science Education
Authors: Fetters Carol , Ortlieb Evan , Cheek Earl H.
Published: October 2017

This qualitative exploration was designed to examine strategy-based reading instruction using science expository text in grades 2-5. This study centered on case studies of six elementary teachers and how they used reading strategies during science instruction. Findings revealed that although the teachers’ use of expository text was limited, teachers utilized particular reading strategies that extended and elaborated the students’ oral discussions during science instruction. The classroom conversations about science topics extended the students’ background knowledge of the science concepts that related to science expository text materials in grades 2-5. Further research could include alignment of reading strategy instruction with science instruction using print materials that are matched with the students’ instructional reading levels.
Lessons from the Bloody Rain: The Young Vic Production of A View from the Bridge and Miller's Tragic Form
Authors: Larner Daniel
Published: October 2017

This article examines the nature and structure of the tragic experience as encountered and revealed in the Young Vic, Ivo van Hove production of Arthur Miller's A View from the Bridge (New York, 2015). Miller's own writings on tragedy are critically examined against a backdrop of tragic theory, and a new vision of Miller's use of tragedy in this play emerges. Rigid definitions of tragedy are eschewed in favor of rich descriptions. Critical issues include the “size” of the action, the moral stature of the central character, the magnitude of the loss, and the dimensions of the tragic vision. This essay argues that the production's use of the chorus in the play leads us to a profoundly shocking experience, which both breaks the heart and expands it, exalting the vision the tragic experience releases at the bitter end of this production.
A View from the Bridge: The Absurdity of Tragedy
Authors: Marino Stephen
Published: October 2017

This article examines how director Ivo van Hove's groundbreaking production of A View from the Bridge reimagines Miller's realistic play. Van Hove transforms the tragedy into raw symbolic theater that employs many elements of the Theatre of the Absurd. This staging remakes the role of the narrator, Alfieri, who questions the meaning of Eddie Carbone's tragic ending and consequently may shed light on Eddie's possible homosexual desires.

Cambios en el uso del suelo en el municipio de Álamos, Sonora - México
Authors: Ramírez García Adán Guillermo
Published: October 2017

En el marco del desarrollo territorial, este trabajo analizó el cambio de uso del suelo y vegetación en el municipio de Álamos, estado de Sonora - México, para el periodo comprendido entre los años 1980 y 2001. El área de estudio caracterizó un rezago productivo, el alto índice de marginación y la sobreexplotación de los recursos naturales principalmente a causa de las actividades agropecuarias.El objetivo fue identificar la magnitud y distribución espacial del cambio de uso del suelo. Para la obtención del mapa de cambio de uso del suelo se utilizó la cartografía existente elaborada en distintas fechas y por diferentes autores, y se realizó una sobreposición mediante el empleo de un sistema de información geográfico (SIG), utilizando el programa ArcView GIS versión 3.2. En el periodo de estudio, los resultados muestran que la agricultura de temporal disminuyó de 73 688 a 57 588 hectáreas; los pastizales cultivados aumentaron en un 1.050%. En el caso de los matorrales, prácticamente todos perdieron superficie y en algunos casos desaparecieron.En cuanto a los bosques, el de pino–encino fue el único que perdió superficie (56%) al cambiar de 47 019 a 20 656 hectáreas. La selva baja caducifolia y subcaducifolia tuvieron una pérdida de 23% de su superficie. La superficie ocupada por los cuerpos de agua disminuyó en aproximadamente 40%, al reducir su superficie de 7963 a 4747 hectáreas. Sin duda la importancia económica de la actividad ganadera en el municipio es uno de los factores que explican los resultados encontrados.Producción Agropecuaria y Desarrollo Sostenible, Vol. 5, 2016: 13-30

Taking into account the critical contributions of social philosophy to the most pernicious elements of capitalist modernity, Which find their most extreme expression in the globalized society, the connection between moral degeneration, the role of education and the dangers faced by democracy under the infuence of certain hostile elements is pointed out, like the market, the corporate culture, and the interests that are inherent to them.Realidad: Revista de Ciencias Sociales y Humanidades No. 148, 2016: 169-184
Cincuenta paradojas del siglo XX
Authors: Ribera Ricardo
Published: October 2017

This essay makes an overview of relevant events of the first half of the Twentieth Century deploying an innovative and appealing procedure. It uses anecdotes and curiosities that engage the reader and avoid the boredom that historic topics provoke among the younger generations. The superfcial can be a way of access to more profound issues and the irrelevant a way to the essential. This methodology mantains, nevertheless, the primordial goal of historical studies: the interpretation of facts over the erudition of data, refection on meaning before a fruitless memorization of events. Addressed in such a manner, if history is to teach something, it is to think critically.Realidad: Revista de Ciencias Sociales y Humanidades No. 148, 2016: 27-59
Desborde emocional y ficción ética en las novelas centroamericanas de guerrilleros
Authors: Leyva Héctor M.
Published: October 2017

The following essay explores a series of Central American novels from the 1960s to the 1980s, especially Pobrecito poeta que era yo… by Roque Dalton. The analysis begins with the premise exposed by Brian Massumi which sustains that when bodies encounter, collide and rub with each other they unleash emotive and intellective currents that are prone to be captured by the semantic grids of ideologies. This assertion is close to that of Judith Butler about the selfrefective turn which constitutes the subject in its attachment to a normative power. The essay would attempt to show the mode in which these novels allow to recognize an emotional overfow in contact with social realities and models of revolutionary ethics by which they were captured and helped to conform the guerrillero as heroic figure.Realidad: Revista de Ciencias Sociales y Humanidades No. 148, 2016: 61-80

Authors: Fernández Nadal Estela
Published: October 2017

The paper aims to contribute to the breakdown of the “masculine monologue” that, according to Raúl Fornet-Betancourt, unfairly traverses the history of Latin American philosophy, ignoring the long female role in that field of knowledge. For this purpose, it proposes an approximation to the critical philosophy produced by three latinoamerican women thinker. They are: brazilian Ivone Gebara, who develops a critical epistemology of modern philosophy and theology from an ecofeminist point of view; bolivian Silvia Rivera Cusicanqui, who elaborates the theory of internal colononialism and a conception of historicity in which the present is inhabited by a multi-temporality; and ítalo-mexican Francesca Gargallo, who brings a profound fieldwork and a solid theoreticalcritical interpretation about communitarian feminisms in the indigenous women of the continent.Realidad: Revista de Ciencias Sociales y Humanidades No. 148, 2016: 149-167

A determinação da maturidade e do momento adequado de colheita são aspectos importantes a serem considerados na produção de sementes de alta qualidade. Objetivo deste trabalho foi estudar o processo de maturação de sementes de pimenta, variedade Dedo-de-moça, com a finalidade de determinar a época de maturidade fisiológica das sementes, bem como a tolerância das mesmas ao retardamento de colheita. A partir de 50% dos botões florais em antese, as flores foram etiquetadas e os frutos foram colhidos aos 30, 45, 60, 75, e 90 dias após a antese (DAA), sendo avaliados quanto à coloração. A qualidade fisiológica das sementes foram avaliadas quanto ao teor de água, massa de matéria seca, germinação, primeira contagem de germinação, índice de velocidade de emergência e envelhecimento acelerado. As sementes atingem o máximo acúmulo de matéria seca (maturidade de massa) aos 74 dias após antese, sendo que a maturidade fisiológica das sementes (máximo de germinação e vigor) ocorre no período de71 a81 dias após a antese, que representa uma soma térmica de1064,28 a1128,53 graus dias.

Published: October 2017

O comportamento não estacionário de séries de dados hidrológicos configura-se como um desafio para a gestão e planejamento dos recursos hídricos, pois o modelo atual considera que não há alterações significativas nas series hidrológicas ao longo do tempo. Neste contexto, o objetivo deste trabalho foi verificar o comportamento no regime fluviométrico no Rio Paraopeba, MG, em decorrência das modificações da cobertura vegetal. A estação fluviométrica utilizada está localizada no município de Juatuba, MG. A série possui período de observação de 76 anos (1938 a 2014). Para a verificar a hipótese de estacionariedade e de tendência temporal foram utilizados os testes de Spearman e Mann Kendall com nível de significância de 5%. A verificação da alteração da cobertura vegetal foi utilizado o Índice Vegetativo por Diferença Normalizada (NDVI), obtido através da plataforma Google Earth Engine (GEE). Observou-se aumento das áreas de cobertura vegetal com alto vigor vegetativo na região correspondente a área de contribuição da estação fluviométrica, o qual pode ter influenciado na tendência de redução das vazões máximas e mínimas.

thin films with transition hard AlCrN interlayer deposited by magnetron sputtering and
PACVD technology respectively were used. Observations of topography were made using
a scanning electron microscope (SEM), and the atomic force microscope (AFM). The
structure of samples was performed using a Raman microscope. The microhardness tests
of thin films were made by Oliver & Phare method.
Findings: Studies confirmed that the combination of research SEM and AFM provide
crucial information on the structure and topography of the samples. It was possible to obtain
information about the topography parameters and allow for the assessment of morphology
and quality of the tested coatings. Study of the structure using Raman spectroscopy
revealed the band corresponding to the DLC and TiC thin films.
Practical implications: The current application areas for low friction thin films are
constantly growing, and the intensive development of techniques requires the use of new
technologies what leads to the production of the specific surface layer and a thorough
examination.
Originality/value: Growing area of low friction coatings with specific properties requires
the use of specialized tools aimed at assessing the topography and structures which are
responsible for tribological properties.
Influence of the conditions of casting and
heat treatment on the structure and
mechanical properties of the AlMg10
alloy
Authors: Kordas P.
Published: October 2017

Purpose: Assessment of the possibilities of shaping the structure and improvement
of mechanical properties of casting from AlMg10 alloy through a selection of casting
technology and precipitation hardening.
Design/methodology/approach: the work evaluated the impact of casting and heat
treatment technology on the mechanical properties and structure of AlMg10 alloy castings.
The tests were performed on 200 mm × 100 mm × 25 mm plate castings produced by
gravity casting methods for sand and metal moulds and by a liquid state press moulding
technology. Castings made with these technologies solidify in substantially different heat-
evaporation conditions and exhibit varying degrees of primary structure fragmentation.
Metallographic and strength tests were performed on raw castings and after heat treatment.
Findings: The changes in the morphology and size of primary crystals and the dispersion
of the reinforcing phase according to the casting solidification rate and the precipitation
hardening treatment were analyzed. Solidifying castings in the form of sand show a globular
structure, whereas in die and press castings, a typically dendritic structure occurs, with the
dendritic crystals in pressed castings being much smaller in size than the die castings. In
castings which were not heat-treated, the reinforcing phase of Al3Mg2 occurs in interdendritic
spaces, and its dispersion increases with the rate of cooling. After supersaturation and
ageing treatments, the phase α has a grain structure in all samples. The largest dispersion
of reinforcing molecules is characterized by press castings. In a raw state, the highest
mechanical properties are shown by castings made in the form of sand and the method of
pressing in a liquid state. Heat treatment of AlMg10 alloy castings significantly influences
the increase of mechanical indexes in all castings investigated. The highest features of Rm
are approx. 330 MPa and A5 above 10% is obtained in castings made by the press method.
Research limitations/implications: Particular attention should be paid to the avoidance
of the effects of slag inclusion, shrinkage and magnesium oxidation during casting of
AlMg10 alloys. In die castings of a plate type, due to own stresses, a significant decrease in
mechanical properties occurs.
Practical implications: The most advantageous mechanical properties of AlMg10 alloy
castings are obtained by using liquid-state pressing technology. In addition, this technology
makes it possible to produce thin-walled castings of high dimensional accuracy, high air-
tightness, fine grain structure, lack of surface defects and low roughness.
Originality/value: The paper presents the possibility of improving the mechanical
properties of AlMg10 castings by applying heat treatment. It has been proven that the
casting method has a significant effect on the mechanical properties of the castings.
ECONOMIC AND FINANCIAL CONDITION OF AGRICULTURAL
PRODUCTION COOPERATIVES IN POLAND
Authors: Adamski Marcin
Published: October 2017

The aim of this study was to present the changes that occurred in the group of large-scale farms functioning
in a form of agricultural production cooperatives (APC) in 2013-2015. Due to little availability of information
concerning this form of farms in Poland, the data for the analysis were gathered from the database of the Institute
of Agricultural and Food Economics National Research Institute. This database was created in connection
with the annual publication of Top 100 APC. The analyses show that the surveyed group of cooperatives in
2015 reached a worse financial ratios than in previous years. However, this did not result in discontinuation
of investment and modernization in these farms.
OPPORTUNITIES AND BARRIERS TO THE IMPLEMENTATION OF THE AGRI-ENVIRONMENT PROGRAM ON THE EXAMPLE OF FARMS FROM THE MUNICIPALITY OF MŁAWA
Authors: Gotkiewicz Wojciech
Published: October 2017

The aim of this article is to analyze and evaluate the factors affecting the low level of interest of farmers in the agri-environment program. Modern agriculture in significant contributor to environmental degradation. To prevent this, the EU has created many instruments, including a mandatory agri-environment program. Based on the research conducted in 2016 in the Mława County on two groups of farmers (45 beneficiaries of the program and 45 people who did not join it), the program is an effective tool, but not without defects. The most important of them is too much emphasis on formal issues, which causes many farmers, especially the older and less educated, to be afraid of joining the program. There is also a lack of research that will answer the question of whether and how the program affects the preservation of natural resources. Eliminating these barriers would certainly increase the number of beneficiaries of the program, thus contributing to an even better protection of the environment.
EUROPEAN UNION CLIMATE AND ENERGY POLICY – CHALLENGES
AND CHAINS FOR THE DEVELOPMENT OF RURAL AREAS
Authors: Gradziuk Piotr , Gradziuk Barbara
Published: October 2017

The main objective of the article is to identify the implications of implementing climate and energy policy for rural
areas.Due to their quantitative and qualitative potential, rural areas participate to a significant degree in the achievement
of the indicative targets resulting from the climatic package. Thanks to the production of biomass and, increasingly often,
energy itself during the 2006-2016 period, the share of RES (renewable energy sources) in the production of primary
energy grew twofold from 7.8% to 13.9%. Biomass was the main source, but since 2010 the use of wind and sun in the
production of energy has been growing rapidly. Based on the analysis, it can be argued that by 2050 most of the energy
and renewable energy resources will be produced in agriculture and rural areas. Implementing the commitments stemming
from EU climate and energy policy can be an impetus for rural development.
ECONOMIC AND ENVIRONMENTAL SUSTAINABILITY OF AGRICULTURAL HOLDINGS WITHOUT ANIMAL PRODUCTION
Authors: Kołoszko-Chomentowska Zofia
Published: October 2017

This article undertakes to evaluate the economic and environmental sustainability of agricultural holdings not engaged in animal production. Studies covered agricultural holdings in the Podlaskie voivodeship included in the FADN system in 2014. The evaluation accounts for selected agri-ecological indicators, supplemented by material pressure indexes and economic indexes (profitability of land and labour). Obtained results indicate that environmental sustainability conditions were met only with regard to the vegetation cover index but were not met with regard to the remaining indexes (share of permanent grasslands, crop structure, balance of organic substances). Holdings without animals exerted lesser pressure on the environment than holdings engaged in animal production from the perspective of consumption of means of production. Both groups of holdings did not achieve economic sustainability. Income parity in 2014 amounted to 0.73 for holdings without animals and 0.84 for holdings with animal productions.
THE CONTRACT OF LEASE OF AGRICULTURAL PROPERTY
OF THE TREASURY IN THE LIGHT OF FREEDOM OF CONTRACT
Authors: Majchrzak Adam
Published: October 2017

The study discusses the issue of concluding an agreement for the lease of state agricultural land,
which is now the basic form of management of APSST real estate. From the point of view of the principle
of contractual freedom, circumstances which, under the applicable legal norms, limit this principle are
presented. In addition, key elements of the contract are presented from the point of view of the tenant’s
interest. Considerations lead to the conclusion that the protection of the public interest is more important
than the stability of tenure for tenants.
EVALUATION OF SOCIO-ECONOMIC POTENTIAL OF RURAL AREAS
IN MAZOVIECKIE VOIVODESHIP IN 2004 AND 2016 ACCORDING
TO THE SELECTED CONCEPTS OF THE REGIONAL DIVISION
Authors: Pomianek Iwona
Published: October 2017

The aim of the article is to compare and evaluate the socio-demographic potential of semi-urban and rural LAU 2 units
in the Warsaw Metropolitan Area, the area of Integrated Territorial Investment and new regions (PL91 and PL92 NUTS 2
units) in the light of the concept of division of Mazowieckie Voivodeship since 2018. Both in 2004 and 2016 the high level
of the potential characterised mostly units located within Warsaw: only one unit from the capital area was ranked as of low
socio-demographic potential in 2004. The most favourable values of socio-demographic indicators were recorded in the
ITI area, which proves the high attractiveness of these communes. There were also observed some positive changes in the
values of the analyzed socio-demographic indicators, also taking place (although more slowly) in the non-metropolitan and
peripheral areas.

Published: October 2017

In the paper the farmers’ opinions about the problems of natural environment protection has been discussed from the point of view of sustainable development. The analyses revealed that in general farmers were aware of negative changes ongoing in the natural environment, however they don’t link them with the negative consequences of agricultural production. Over a half of the respondents declared knowledge of the concept of sustainable agriculture - many of them correctly identified the fundamental principles of this concept as well.
THE ECONOMIC COMPARISON OF CAGE AND DEEP-LITTER SYSTEMS IN HUNGARY
Authors: Szabó Virág
Published: October 2017

It is all the more difficult for the actors to hold their ground on the global market of caged egg
production, that is why I believe it is important that the producers be able to judge their own competitivity,
and bring their economic decisions based on this. However, the issue is raised whether the move
towards alternative technologies indeed creates the opportunity of competitive management, so the aim of
my research is the analysis of the economic relations of laying hen farms producing in different keeping
technologies. There was no example in previous studies of a detailed economic comparison of the cage
and deep-litter system from a national database in Hungary, so the cost-benefit analysis of these systems
from Union accession to 2014 will lead to new scientific results.
CHANGES IN YIELDING OF VARIETIES OF WINTER WHEAT AND RYE IN VARIETY TESTING IN POLAND
Authors: Wicki Ludwik
Published: October 2017

The aim of the study is to determine the significance of varietal progress and changes in level of inputs on changes in yield level of winter wheat and winter rye varieties in conditions of variety testing. The analysis covered the years 2006-2016. The data from post-registration varieties testing coordinated by COBORU were used. It was found that the yield of winter wheat varieties in varieties testing network increased by 12.5 and 13.8 dt/ha in the analyzed period respectively at lower and higher intensity of production. The share of biological progress in observed growth was estimated at level 60 and 38%, respectively. The average annual increase of yields as a result of biological progress was determined at level of 0.92 and 0.58%. For rye the yield growth was 7.4 and 8.5 dt/ha, and the share of biological progress in this increase was determined at level of 41 and 32%. The average annual yield increase resulting from biological progress was 0.50 and 0.38%. The higher effects of biological progress were observed for the lower level of production inputs. Biological progress in cereal production still plays a significant role in the increase in yield. For winter wheat and rye the share was calculated at level 30 to 60% depending on intensity of production and was higher for wheat. Another important factor in achievement yield increasing is correct technique of production, especially proper level of inputs. Under conditions of high-intensity production, the importance of introducing new varieties decreases. Taking it into account, research in the field of plant breeding in future should be more strongly oriented towards obtaining resistance to biotic and abiotic stresses.
