    Opis:
    Sustainable Agriculture innovations include least soil unsettling influence, lasting soil cover through yield deposits or cover harvests, and yield revolutions for accomplishing higher profitability. In India, endeavors to create refine and scatter preservation based farming advancements have been in progress for almost two decades and gained huge ground from that point forward despite the fact that there are a few imperatives that influence Sustainable Agriculture. Especially, huge endeavors have been made on no-till in wheat under a rice-wheat pivot in the Indo-Gangetic fields. There are a greater number of settlements than tradeoffs for selection of Sustainable Agriculture be that as it may; the balance among the two was comprehended by both adopters and promoters. The advances of Sustainable Agriculture give chances to decrease the cost of generation, spare water and supplements, increment yields, increment trim expansion, enhance effective utilization of assets, and advantage the earth. Nonetheless, there are still requirements for advancement of Sustainable Agriculture advances, for example, absence of suitable seeders particularly for little and medium scale agriculturists, rivalry of yield buildups between Sustainable Agriculture utilize and domesticated animals sustaining, blazing of yield buildups, accessibility of talented and logical labor and conquering the inclination or outlook about culturing. The need to build up the arrangement Sustainable Agriculture sing and procedures is pressing to advance Sustainable Agriculture in the district. This article audits the developing worries because of constant selection of ordinary farming frameworks, what's more, examinations the imperatives, prospects, arrangement issues and research requirements for preservation Agriculture in India.

    Opis:
    The elimination of low-emission sources harmful to human health, mainly domestic boilers, has recently grown into a nation-wide problem in Poland. Emissions of harmful substances from power plants are many times lower than from domestic coal furnaces and are subject to strict regulatory regimes. Hence, companies of the professional and thermal power industry can play an important part in the process of liquidation of low emissions by offering to replace the combustion of coal in home furnaces with the use of it for the production of electricity and system heat in electrical cogeneration, which can then be used for home heating purposes. In addition, it is essential for the professional power industry to maintain a constant daily load of power units, so that the loss of efficiency in regulatory work, increased failure frequency or the need for frequent commissioning does not negatively affect the economy of production. Therefore, the selection of the part of the dispersed heat market that can be replaced with system heat and the use of electricity for heating purposes, while contributing to the elimination of low emissions and improving the economy of new energy units by increase their work in the night low demand periods, must be carried out properly.

    Opis:
    The article proves a particular bias in the agricultural land use for assessing the ecological and economic efficiency of only cost indicators. The methodology for evaluating the ecological and economic efficiency of agricultural land use by the energy content of foods is considered. The purpose of the article is to consider the methodology and justification of the practical significance of assessing the environmental and economic efficiency of the agricultural land use by the energy content of products. The article presents the initial ata for correlation-regression analysis on the average performance of agricultural producers of Ukraine to determine the weight of each indicator. We used land statistical collections, National reports on the state of the environment in Ukraine for the period 2012–2018. The analysis was carried out based on the average performance indicators of agricultural producers of Ukraine to determine the weight of factors and leverage on the ecological and economic efficiency of agricultural land use. The output of a unit of land in relative terms through exchange energy is not only a kind of indicator, a criterion for the efficient use of agricultural land but also a criterion for the effectiveness of all production activities of agricultural producers, a particular district, and even regions. The main advantage of the proposed approach is the focus on achieving the ultimate goal of agricultural production, which allows us to recommend it for extended use in assessing the ecological and economic efficiency of agricultural land use.

    Opis:
    Power stations in marine locations cause multi-faceted impact on the environment, man and the economy. There are not many studies devoted to modeling energy benefits for CO2 emissions. The paper presents the issues of assessing the efficiency of offshore wind farms, defined as the ratio of benefits to life cycle inputs. The scientific goal was to develop a mathematical model for efficiency in the design, manufacture, use and management of offshore wind power. The papers practical purpose is the experimental designation of the impact of selected post-use management methods, time of use and maritime location, i.e. average annual productivity of wind power plants on the efficiency of energy benefits from greenhouse gas emissions. The mathematical model of the integrated cost-benefit ratio has been developed for energy use assessment, taking into account the benefits generated by electricity production and the life-cycle CO2 emissions based on the LCA analysis using the CML method. Mathematical model validation was performed by determining the value of the indicator for an existing 2 MW offshore wind farm and comparatively for fossil fuel production: lignite, stone, fuel oil and natural gas. Analytical and research work carried out showed that the higher the efficiency index, the higher the value of the indicator. It has been shown that the location of the power station at sea produces more favorable CO2 elimination rates, due to higher productivity compared to in-land wind power plants. A more favorable form of post-consumer management for CO2 has been determined as recycling. It was found that for electricity generated from offshore wind farms, the value of the energy efficiency benefit from CO2 emissions is higher than for fossil fuel energy production.

    Opis:
    Research background: The value of clusters in developing advanced technology products and services as well as promoting regional growth is acknowledged by many policymakers and researchers (Lee et al., 2012). Hence, clusters are identified as enablers of the circular economy and resource efficiency in this study. Companies aim to enhance competencies and create competitive advantages in global competition and this can be achieved through pulling from a common and accessible pool of resources, information and demand for innovation which means that companies can profit from belonging to a cluster. Purpose of the article: The main aim of the article is to overview the scientific literature that addresses the circular economy, identify clusters and their role in the circular economy and suggest how small and medium enterprises could engage in a circular economy through clusters' performance development. Methods: Bibliometric literature analysis enables identifying the latest trends in scientific articles regarding a circular economy and clusters. The analytical hierarchy process (AHP) allows for composing the scheme of the cluster?s competitive advantage within circular economy. Findings & Value added: The findings suggest that resource efficiency is considered to be one of the most important ambitions and clusters can work as enablers of a circular economy for small and medium enterprises (SMEs), gaining a competitive advantage at the same time. Clusters can encourage and provide conditions in which SMEs would turn to a circular economy. The scheme of Cluster's competitive advantage proposed by the author can help cluster's coordinators, policymakers and all the concerned parties to verify the importance of clusters' involvement in the circular economy.

    The article considers a comprehensive study of the problem of land relations development in the region. It identifies the main directions for their further development, which include improving the legislative framework, economic and monetary valuation of land, leasing land relations and ensuring the formation of a market for agricultural land and ecologically safe land use. The article aims to determine the interrelated components of the organizational and economic mechanism for managing land resources of agricultural enterprises in the context of ensuring land-use efficiency based on the choice of a land-use optimization model. The theoretical and methodological bases for the development of land relations in the conditions of market economy formation are generalized. The directions for improving the ecological status of agricultural land are justified. The state regulation of land relations is analyzed, and ways to improve land legislation are proposed. The directions of the formation and development of the agricultural land market are justified. The ways to improve the ecological condition of the land, taking into account the regional characteristics of the Vinnytsia region, are proposed. To determine the relationship of rational use and reproduction of resources, considering the problems of choosing the optimal strategy for the impact of the economy on the ecologization of land resources, the system of rational use and reproduction of natural resources is developed. The optimization model describing the conditions for the process of stimulating landowners and land users in the direction of protection and rational land use is established.

    Opis:
    Zadania podjęte przez Radę Ministrów dotyczące polityki energetycznej Polski, zobowiązują do zwiększenia o 15% udziału OZE (Odnawialnych Źródeł Energii) w energii finalnej oraz pobudowania 2000 biogazowni rolniczych produkujących nie mniej niż 1,7 mld m³ biogazu w 2020 roku. Dla zrealizowania powyższego planu, zakłada się wykorzystywanie głównie biomasy z roślin uprawnych poprzez spalanie w elektrociepłowniach oraz fermentację w biogazowniach rolniczych, wykorzystujących również substraty odpadowe. Zapotrzebowanie na biomasę do 2020 roku wynosi według szacunku IUNG-PIB ok. 10,0 mln ton suchej masy, w tym 3,0 mln ton słomy i 2,0 mln t biomasy z lasu. W celu poznania przydatności jednorocznych roślin uprawnych, przeprowadzono w latach 2007 – 2009 w Zakładzie Doświadczalnym Stary Sielec porównanie następujących gatunków: sorgo, kukurydza, konopie włókniste, pszenica ozima, pszenżyto ozime i żyto jako poplon ozimy. Doświadczenia przeprowadzono na glebie lekkiej zalegającej na glinie (kl. IV). Dlatego ich wyniki będą miały zastosowanie w praktyce na glebach gorszej przydatności rolniczej i opadach < 550 mm rocznie. Na podstawie dotychczas uzyskanych wyników można rekomendować uprawę sorga i kukurydzy, które plonują > 20 t/ha suchej masy przy niskich kosztach produkcji (< 10 zł/GJ) oraz uprawę żyta w poplonie ozimym. Najwyższą wydajność energetyczną uzyskano w uprawie kukurydzy na ziarno, użytkowanej na potrzeby energetyki łącznie ze słomą (527 GJ/ha). Natomiast wykorzystywanie ziarna zbóż na cele energetyczne daje najgorsze wyniki (94 GJ/ha) stanowiące zaledwie 20% wydajności energetycznej kukurydzy lub sorga. Z powyższych powodów przeznaczanie ziarna zbóż na spalanie jest nieuzasadnione (za wyjątkiem ziarna skażonego).
    Polish Council of Ministers (the Cabinet) has undertaken to implement energy policy and committed itself to boost the share of energy produced from renewable energy sources (RES) in the final energy output by 15%, as well as to erect 2,000 agricultural biogas plants that would produce no less than 1,7 bn m³ of biogas by 2020. In order to achieve the above, it is assumed that the biomass will primarily be obtained from cultivated plants to be combusted in combined heat and power (CHP) plants, or fermented in agricultural biogas plants, which will also use waste substrates. The Institute of Soil Science and Plant Cultivation (IUNG-PIB) estimates the demand for biomass to amount by 2020 to 10,0 mln t dry mass, including 3.0 mln t of straw and 2,0 mln t of forest biomass. In order to investigate the usability of cultivated annual plants, a comparison of the following cultivars was performed by the Stary Sielec Experiment Plant from 2007 through 2009: sorghum, maize, hemp, winter wheat, winter triticale, and rye as winter aercrop. The experiment was conducted on light soil occurring on loam (class IV). Therefore the results obtained can be practically applied to the soils of lower agricultural quality given the annual rainfall of < 550 mm. On the basis of the results obtained so far the cultivation of sorghum and maize can be recommended, as these cultivars yield > 20 t/ha of dry mass at low costs (< PLN 10/GJ); another recommendation concerns rye as winter aercrop. The highest energy efficiency was obtained from the cultivation of maize grown for grain, used for power industry in combination with straw (527 GJ/ha). The lowest results (94 GJ/ha) have been obtained when using cereal grain for energy purposes, as it has only 20% of energy efficiency of maize or sorghum. These results prove that it is unjustified to designate grain for combustion (with the exception of contaminated grain).
