Abstract

Agri-food systems include branching ramifications, which connect in the upstream the input suppliers with farmers, and downstream farmers, processors, retailers and consumers.

In the last decades, at the level of the regions, food systems have undergone rapid transformation as a result of technological progress.

The paper analyzes the changes made to the structure, behavior and performance of the agri-food system and the impact on farmers and consumers. Also, the role of agricultural research as a determinant factor of transformation of agri-food system is analyzed.

The research objective is to develop technologies that cover the entire food chain (from farm to fork) and meet the specific requirements of consumers (from fork to farm) through scientific solutions in line with the principles of sustainable agriculture and ensuring the safety and food safety of the population.

Abstract

In the last decades, the awareness of the harmful effects of environmental pollution on the quality of life of human beings has greatly increased.

This awareness led to the legal regulation of the fundamental right to breathe fresh air, to drink clean water and to eat safe food. Among the concerns of the European institutions, we highlight the right to a healthy environment, as recognized in the Stockholm and Rio statements, but also the consumer’s right to use safe consumer products.

Creating a framework of principles and procedures in accordance with the Universal Declaration on Human Rights, to guide States in the formulation of bio-laws, policies or other instruments in the field of bioethics, legislation to protect and promote the interests of present and future generations and to emphasize the importance of biodiversity and its conservation as part of the common heritage of humanity.

Abstract

The results of energy estimation of a crop rotation link in the western part of Forest Steppe of Ukraine are presented. It is established that all proposed fertilizer systems are effective in terms of energy storage. It is proved that the use of mineral fertilizers in combination with organic fertilizers increases Kee indices by a factor of 1.2.

Abstract

Eco-efficiency is based on environmental, social and economic principles, focusing not only on the use of fewer natural resources (raw materials) and energy but also on the cost-effective use of new technologies (eco-innovation) for the same volume of production and generation of low waste (efficient production). Agro-ecosystems globally, once with the development of the pesticide industry (plant protection products) and under the influence of aggressive marketing, have been based on the large-scale application of big amounts (perhaps too high) of pesticides. Many of the pesticides used in agriculture have a high persistence and degrade very slowly, which leads to the soil, water and even air pollution, with negative effects on plants, animals and, implicitly, humans. If these are used in short term and at low concentrations, pesticides can have beneficial effects (crop protection and their conservation and prevention of vector-borne disease) but in large quantities and applied over a long period of time can be toxic to humans and with a negative impact on the environment and ecosystems (degrading essential ecosystem services).

Abstract

On the international scene, Europe expresses its views and acts concerted at an economic and political level, from trade and trade agreements to citizens’ safety and security as priority areas.

Member States’ security cooperation has become routine. But the EU-27 is still the main promoter of European citizens’ food safety and security through sustained, transparent and sustainable deners, in order to combat climate change, limiting the use of bioresources conservation of genetic resource biodiversity.

One of the strongest enemies of biodiversity is “poverty” and protection against it necessarily implies improving the well-being of humanity and fighting against underdevelopment.

Abstract

Although relatively recent, peach culture has grown great in our country due to the special quality of the fruit, its very complex chemical composition and the large production that can be obtained without much effort. Peach is a species slightly adapted to our climatic conditions, suffers from winter frost, but can provide productive and long productions of 10-15 years.

Abstract

Cannabis cultivated as the main raw material for textiles is another than the one used for its psychotropic effects. From a botanical point of view, however, plants are virtually imperceptible.

What is changing is the concentration level of the active principle, depending on the type of cannabis. Cannabis Indica has a higher amount of resin and a higher cannabidiol percentage than the Sativa variety.

The hemp cultivated for fibers and especially Cannabis sativa L, which includes the types grown in Romania and generally in Europe, have a low content of narcotic and hallucinogenic substances (0.2-0.3%). This hemp is specially formulated and used for the production of fibrer.The hempcultivated for drug is not grown in. Romania. Because there are no processing plants factories, all the production in Romania is sold for export. Subsidies are given for the cultivation of these varietes. The benefits are great because textiles obtained from hemp are superior to those from countries like China and Germany. The hempcultivated for drug is not grown in Romania.

Abstract

This work was conducted on 23 samples distributed between springs, wells and boreholes tapping the shallow and deep aquifer in the M’Daourouch-Drea area located in extreme northeast of Algeria. Ca2+, Mg2+, Na+, K+, Cl, SO4 2−, HCO3 and NO3 were analysed. The interpretation of the geological-geophysical data allowed us to highlight two aquifers. The first consists of conglomerates, sandstones, gravels, sands, marls, limestones, lacustrine and alluvial deposits varying in thickness from a few tens to a few hundred meters, representing Neogene-Quaternary filling of the studied basin. The second is more important localized in the cracked and karstified limestones of upper Cretaceous age; these limestones are outcropped on the flanks of the syncline and the borders of the basin. The first aquifer sometimes rests directly on the second which allows hydraulic communication between them. The hydogeochemical and statistical study, with the combination of numerous tools, indicates that the chemistry of groundwater in the M’Daourouch-Drea Plain is controlled both by the dissolution of the minerals of the evaporite formations and those of the carbonate formations.

Abstract

At the end of 2016 there were 84 wind farms under construction in 11 European countries. Investments in this sector are enormous. The average cost of a wind farm construction amounts to approx. 4 mln EUR per 1 MW of installed power. Offshore wind energy production also plays a significant role in the process of ensuring energy security in Europe, and in reduction of greenhouse gases. The objective of this paper is to present prospects of offshore wind energy farms development in the leading member states of the European Union as regards this problem. In this paper offshore wind farms in Germany and Denmark have been studied. In the paper the power of wind farms, the support systems as well as criteria related to location of wind farm offshore have been analysed. German and Danish sectors of offshore wind energy are strongly supported by respective governments. Both countries aim at yearly increase of wind energy share in total energy production. The research has been conducted based on the analysis of acts, regulations, the subject’s literature and information from websites.
