AbstractOver the past 10 years, the organic sector has expanded continuously in Europe due to policy support and a growing market demand for organic products. In line with this development, many farmers converted to organic farming each year. Nevertheless, the total number of organic farms has not increased constantly in Europe. In several countries, the absolute number of organic farms actually decreased in some years of the past decade. Some of the deregistered farmers gave up completely; others reverted to conventional agriculture. Against this background, this article aims (i) to give an overview of the extent of reversion to conventional agriculture in Europe based on statistics, (ii) to conceptualize the decision to revert in the form of a theoretical model, (iii) to compare farmers’ reasons to revert to conventional farming based on existing studies, and (iv) to identify further research needs. The importance of reversions to conventional agriculture is difficult to determine with the existing data, especially as in most cases it is not recorded as to what happened to the farms after deregistering from organic certification. The data nevertheless show that there are large fluctuations in the organic sector with many farmers entering and exiting each year. In order to reveal the farmers’ reasons for deregistering, various qualitative as well as quantitative surveys have been carried out already. For most farmers, the decision to revert is a result of different factors. Reasons for the reversion of their farms can be classified into economic motives, difficulties regarding certification and control, problems with organic production techniques as well as the farms’ macro environment. In most cases, however, economic reasons played a main role. Suggestions for organic legislation bodies, advisory services and policy makers are derived out of the findings. A deeper understanding of the influencing aspects regarding reversions and the necessary changes in the organic sector to avoid them should be an important objective of forthcoming research.

Increasing use of agrochemicals, higher production cost and deterioration of ecosystem health have advocated the need to change the traditional and external input using agriculture towards safe and sustainable organic production. The article reviewed on general overview of organic agriculture in Nepal. The article aims to put light on the current scenario of the dawdling-paced organic agriculture and the options to revive the pesticide dominated conventional agriculture. Promotion of organic agriculture was first appeared as a priority in the10th Five Year Plan of the Government of Nepal. Now it has been embedded in the national agricultural policy. Organic agriculture provides benefits in terms of environmental protection, conservation of nonrenewable resources, improved food quality, improve health status and the reorientation of agriculture towards areas of market demand. Various institutions, individuals and farmers are engaging in organic farming. Nepal is exporting organic products to international markets. The adoption of organic agriculture increases agricultural production and improves soil health and consumer health and seems a better option in countries like ours where fortunately integrated crop-livestock system is still prevalent. It is found to be viable option for better livelihood in the context of Nepal. Because the haphazard pesticide use has marred the conventional agriculture, all these contexts gesture this system to be scrutinize thoroughly and supplanted by organic farming system as a viable option towards food security and agricultural sustainability.

Organic production (including agriculture, wild culture, forestry and aquaculture) is a worldwide phenomenon that is practiced in at least 172 countries. The Organics Olympiad presents 14 indices of global organics leadership, each at three levels (Gold, Silver and Bronze). The Organics Olympiad of 2016 yields 29 countries as global organics leaders, and confirms that organics leadership is diversely distributed across countries, large and small, rich and poor, developed and less so, and cuts across linguistic, ethnic and cultural boundaries. Australia continues to lead the world in organic agriculture hectares. Australia also leads in the increase of organic hectares over the past four years (since the Organics Olympiad 2012) and in the number of WWOOF (Willing Workers on Organic Farms) hosts. Finlandleads in organic wild culture hectares. Vietnam leads in organic aquaculture hectares, and Tunisia leads in organic forest hectares. Germany leads in biodynamic hectares, as well as with the number of members of IFOAM-Organics International. India leads for the number of organic producers. The Falkland Islands (Malvinas) leads in terms of the percentage agricultural land dedicated as organic. Switzerland leads with the value of organics consumption per capita. USA leads in the value of the organics market. Denmark leads in the publishing of organics research papers over the past four years. Namibia leads in the percentage increase in organic hectares over the past four years. The overall global organics leaders, on the basis of aggregated scores, are Australia, Germany, and Switzerland, in positions one, two and three, respectively. This study demonstrates the successful global diffusion of organics, and identifies that leadership lessons can be available from a broad diversity of countries. Key implications are identified.

In Europe, the goji crop is expanding rapidly, to satisfy the increased market demand for functional foods, with effects in chronic diseases treatment (cancer, diabetes, atherosclerosis, etc.). Romania has become in recent years one of the most important growers of goji berry, especially for organic production, as the species was quite resistant to main pests and diseases. Still, in 2008, a non-indigenous species of Eriophyid mites, called Aceria kuko, was identified on goji plants in UK and spread rapidly throughout the EU. The plant protection institutions took eradication measures, however the pest continued to spread in new plantations and recently on spontaneous plants. Based on GBIF, iNaturalist, personal observations and communication, the paper presents the current distribution of goji berry gall mite in Europe and in Romania and also suggests the use of new citizen science tool - ProtectGoji maps, that aims both to increase awareness of goji producers and consumers about this pest and to geolocate the species expansion in Romania for a better containment and control strategy.

Oil palm is an oil-producing crop of major importance at the global scale. Oil palm mesocarp lipids are used for myriads industrial applications, and market demand has been growing for decades. In addition, oil palm seeds are oleaginous, and the oil extracted therefrom can be used for several purposes, from food to cosmetics. As such, there is a huge need in oil palm seeds to maintain the global cohort of more than 2 billion trees. However, oil palm seed germination is a rather difficult process, not only to break dormancy, but also because it is long and often reaches lower-than-expected germination rates. Surprisingly, despite the crucial importance of germination for oil palm plantation management, our knowledge is still rather limited, in particular about germinating oil palm seed metabolism. The present review incorporates different pieces of information that have been obtained in the past few years, in oil palm and in other palm species, in order to provide an overview of germination metabolism and its control. Further insights can also be gained from other oleaginous model plants, such as Arabidopsis or canola, however, palm seeds have peculiarities that must be accounted for, to gain a better understanding of germinating seed metabolism.

SUMMARYA large body of published research now exists on economic, social, technical and policy related aspects of organic production. The dramatic increase in published research over the last 20 years reflects not only the existence of policy support for organic farming in some countries but also the availability of government funding for research on organic farming. This has resulted in a broadening out of organic research from privately funded, specifically organic research organizations, into universities and mainstream research institutes. In parallel, publication of research results from organic farming has increasingly appeared in refereed literature in addition to literature sources more available to farmers and advisors. Research scientists from Europe, North America and Australasia have all made important contributions to the peer-reviewed literature. The literature is dominated by comparisons of organic and other forms of agriculture, although in many cases these comparisons are not fully valid. Research directed specifically at organic systems is often much more valuable in developing improved production systems than comparative research. Research on organic farming embodies both holistic and reductionist research approaches. Trans-disciplinary research also has an important role to play in understanding the complexities of the ecological approach to agriculture typified by organic farming. Working within the principles and standards of organic agriculture will mean that some research will always be specific to organic production systems. However, in future an increased transfer of knowledge from organic to conventional agriculture and vice versa is envisaged.

Subject. This article assesses the reasons why the economic policy of the Government and Central Bank of Russia does not cause the economic advance. The article tries to find out why the two strategic programmes adopted over the past ten years have not been implemented in most indicators. Objectives. The article aims to analyze the results of financial and monetary policies in Russia over the past ten years, and establish why the Russian economy has been growing within one percent yearly average all these years, and its share in the world economy has not grown, but got reduced even. Methods. For the study, we used the methods of analysis and synthesis. Results. The article proposes certain measures and activities to move to soft financial and monetary policies of the State and corresponding changes in the structure of the Russian economy. This will help ensure six to seven percent GDP growth annually. Conclusions. High loan rates have become the main obstacle to GDP growth in Russia. It is necessary to accept concrete actions and decisions concerning the Bank of Russia key rate, expansion of the functions of the Central Bank of the Russian Federation, industrial policy, support of consumer demand, long-term government contracts for the real sector enterprises, etc.

Over the past decade, on-surface fabrication of organic nanostructures has been widely investigated for the development of molecular electronic devices, nanomachines, and new materials. Here, we introduce a new strategy to obtain alkyl oligomers in a controlled manner using on-surface radical oligomerisations that are triggered by the electrons/holes between the sample surface and the tip of a scanning tunnelling microscope. The resulting radical-mediated mechanism is substantiated by a detailed theoretical study. This electron transfer event only occurs when <i>V</i><sub>s</sub> < -3 V or <i>V</i><sub>s</sub> > + 3 V and allows access to reactive radical species under exceptionally mild conditions. This transfer can effectively ‘switch on’ a sequence leading to formation of oligomers of defined size distribution due to the on-surface confinement of reactive species. Our approach enables new ways to initiate and control radical oligomerisations with tunnelling electrons, leading to molecularly precise nanofabrication.

Background: The therapeutic strategies to manage neurodegenerative diseases remain limited and it is necessary to discover new agents for their prevention and control. Oxidative stress and inflammation play a main role in the pathogenesis of neurodegenerative diseases. The aim of this study is to review the effects of green tea catechins against the Neurodegenerative Diseases. Methods: In this study, we extensively reviewed all articles on the terms of Green tea, catechins, CNS disorders, and different diseases in PubMed, Science Direct, Scopus, and Google Scholar databases between the years 1990 and 2017. Results: The present study found that catechins, the major flavonoids in green tea, are powerful antioxidants and radical scavengers which possess the potential roles in the management of neurodegenerative diseases. Catechins modulate the cellular and molecular mechanisms through the inflammation-related NF-&amp;#954;B and the nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathways. Conclusion: The findings of the present review shows catechins could be effective against neurodegenerative diseases due to their antioxidation and anti-inflammation effects and the involved biochemical pathways including Nrf2 and NF-kB signaling pathways.<P&gt;

Over the past few decades, conventional agriculture has been facing serious crises caused by numerous factors, including poor soil management and the excessive application of pesticides. Thus, alternative production systems have been developed, including agroforestry systems, especially those that produce both energy and food. The objective of this study was to environmentally evaluate the culture of Aleurites fordii Hemls. (Tung) using the Life Cycle Assessment method with the SimaPro 7.3.2 software. The results revealed that in family farms that use less mechanization to harvest crops, the primary category of environmental impact was land use, which included the removal of animal and vegetable species and ecosystem changes. The full impact of this category was 1741.21 m2yr PDF (potentially disappeared fraction). Subsequently, prognostics were established for the reduction of such impacts, and we conclude that Tung has a high potential for agricultural installation with high responsibility to the environment.

AbstractWe analyzed the Korean National Health and Nutrition Examination Survey (KNHANES) database to determine the trends of hypertension treatment and control rate in Korea over the past 10 years. In addition, we tried to investigate the effect of chronic medical conditions on hypertension management. We investigated the hypertension prevalence, awareness, treatment, and control rate from 2008 to 2017. KNHANES, which uses a stratified multistage sampling design, is a cross-sectional, nationally representative survey conducted by the Korean government. A total of 59,282 adults (≥ 20 years) were included, which was representative of the total population of around 40 million Koreans per year. The mean age was 50.7 ± 16.4 years and 42.6% were male. The prevalence of hypertension, hypercholesterolemia, diabetes mellitus, and obesity significantly increased over the 10 years. During this period, the hypertension treatment and control rate significantly improved. Hypertension treatment rate was significantly lower in the younger age group compared to the older age group, but the control rate among the treated patients was not significantly different between age groups. The treatment and control rates of hypertension were higher in patients with multimorbidity, which implies that it has a favorable effect on the treatment and control of hypertension. Hypertension treatment and control rate have improved over the past 10 years. The higher treatment and control rate in patients with multimorbidity suggest that the more aggressive surveillance might be associated with the improvement of hypertension treatment and control rate in Korea.
