Sustainable energy development implies an effective use of economic, human, technological, renewable and non-renewable natural resources. The gradual process of natural environment degradation and the inevitable exhaustion of natural fossil fuel deposits force the search for alternatives. A comparison of alternative opportunities to generate energy allows to identify their advantages and drawbacks. The article attempts a systematic review of factors ‘in favour of’ and ‘against’ the use of renewable energy sources (RES) in accordance with the principle of sustainable development. The study applies descriptive methods, including comparisons. CSO and ERO were the sources of data for 1988- 2018. According to sustainable development principles, investments in RE need to be widely promoted and supported by the state, especially in rural areas. The attempt to systematise factors contributing to the use of renewable energy resulted in the identification of: the importance of economic circumstances and the traditional approach to the energy sector; the need to protect the natural environment by the reduction of pollution and mitigation of the greenhouse effect; the need for continuing the education of society on the implementation and fast development of technology and the desire to enhance self-reliance and independence in energy supply with a special consideration of rural areas.
The aim of this study was to evaluate individual farms which predominantly dealt with crop production, but also kept sheep. Information about the farms’ cash flow was collected by way of direct interviews with the owners of the farms. The cash flow analysis revealed problems with liquidity. Therefore, it was necessary for some farms to have financial resources available for periods of negative financial flows or to be able to sell farm products. The national sheep industry which focuses on the production of lambs for slaughter, gives the opportunity to improve revenue. This was especially necessary in the second quarter, in which a lack of liquidity was observed. The share of income from sheep production in total revenues ranged from 19 to 50%, and proved that keeping sheep as a supplementary activity was beneficial.
Proper environmental project management is a significant element in shaping a positive, pro-environmental image of urban agglomerations and adjacent towns. Environmental resource management and protection, as well as spatial planning in accordance with sustainable development principles, are the most important factors in creating a positive image of, and strategies for, cities. An example of a large, innovative environmental project implementation is the Central Sewage Treatment Plant in Kozieglowy, in the agglomeration of Poznan, and its installations and equipment impact assessment studies. Important aspects of the project were mediations, which took place from May 2011, until the end of April 2012.

The paper reviews the concept of sustainable agriculture, indicating its various dimensions. The similarities between sustainable development and sustainable agriculture are demonstrated. The fundamental objective of the paper is to conceptualize sustainable agriculture in Poland. The paper raises several essential issues concerning the lack of such studies in the past and proposes research objectives. Firstly, to present the main issues of sustainable agriculture and to show the possibilities of implementing the idea of sustain� able development, an evaluation through the prism of change directions and dynamics, as well as regional differentiation of Polish agriculture, was necessary. Secondly, to present the situation in the economic sus� tainability of Polish agriculture in the period 2000-2010, the following research methods were employed: monographic and descriptive methods, analysis and synthesis, induction and deduction. Findings of foreign scientists were also used in the research. The analysis of the condition of agriculture considers the main changes that occurred between the years 2000-2010. These were presented on the basis of Main Statistical Office data from statistical yearbooks and reports of agricultural censuses results.
The analysis of logistics costs in agricultural enterprises in process aspect was carried out in the paper. The aim of the research was to identify those process activities, in which the optimization of logistics costs can influence the realization of strategic aims of sustainable development. As a result of the research, some indexes of logistics costs for agricultural enterprises were estimated. Also, the differences among the costs, depending on the area shape and used technologies, were shown in the paper.
Subject and purpose of work: The aim of the study was to evaluate activities of farms located in the Czarnorzecko-Strzyżowski Landscape Park according to the principles of sustainable development. Materials and methods: Survey research was carried out in the Korczyna commune among randomly selected farm owners at the turn of 2014 and 2015. Results and conclusion: Agricultural production is rather versatile and unspecialized in most of the farm-holdings covered by the study in Korczyna Local Government Area (LGA). Cereals dominate the cropping system, while animal husbandry is predominantly by using the Simmental cattle breed. The farmers are aware that they farm in specific conditions, where sustainable land use is crucial for protecting biodiversity and preserving cultural heritage, thus permitting inhabitants to live in an uncontaminated environment. The Korczyna Local Government Area enjoys favourable conditions for the running of ecological farms, but with farmers visibly lacking in motivation as they consider such farming system as unprofitable, besides requiring lots of time and work.
The Brazilian Amazon supplies the world with several forests ecosystem services, many of which are essential to sustain human life on earth. Nevertheless, the Amazon is threatened by deforestation and degradation implying in reductions on the provision of these. According to economic theory, as ecosystem services are positive externalities and public goods, agents do not take into consideration the costs and benefits of their consumption and production of ecosystem services into their economic decisions. To address this problem payment for ecosystem services – PES – emerged, aiming to provide a source of income to the poor people living in forest areas, stimulating them not to deforest, and making agents who are indebted with the nature pay for their overconsumption of ecosystem services. There is still controversy about possible impacts of the instrument. This article accesses the potentials of PES to contribute to sustainable development in the Brazilian Amazon using the three goals related to sustainable development proposed by the ecological economics theory: efficient allocation, fair distribution, and sustainable scale. The study shows that PES as a pure market approach is unlikely to solve neither the scale nor the distribution problems. Therefore, for PES to achieve sustainable development, markets for ecosystem services should first be constrained by a maximum sustainable scale. Then, measures should ensure fair distribution in second place. Only after these questions have been tackled, it is desirable that agents interact in the ecosystem services markets to lead to an efficient allocation of resources.
The aim of the study is to show the advantages of using horses and modern horse-drawn machines in organic farming. The study presents the benefits derived from using horses in agriculture from the aspects of sustainable development. Workhorses, both in organic farming as well as on small family farms, serve as sources of renewable energy thus contributing to the protection of biodiversity. Modern horse-drawn machines and tools improve farms’ self-reliance, enhances the living standards of on-farm workers, empowers local communities and leads to job-creation. The need for further studies and analysis of the use of workhorses in aspects regarding sustainable development in Poland was also signified.

The role of environmental protection in education

88%
In this report we point out the requirement of local communities for environmental education of society that results from accession of Poland to the project titled „Decade for Sustainable Development 2005-2014”. The paper includes results of the surveys carried out among students, teachers and officers of communes that reveal the role of environmental education in schools, communes and universities. The results demonstrate that environmental education should become connected with actions in aid of both natural and social local environments.
Mit dem Beitritt der neuen Mitgliedsstaaten im Mai 2004 werden die Disparitäten zwischen den Ländern, aber auch zwischen den Regionen in der Europäischen Union um einiges größer werden. Es betrifft sowohl Beschäftigung nach Sektor, Arbeitslosenquote als auch Pro-Kopf-BIP. Es wird die Regionaldifferenzierung auf der Grundlage von diesen Kennzahlen zusammen für alle Regionen, sowie getrennt für jedes Land der Gemeinschaft bestimmt.
