The world’s food production needs to be doubled in order to cover the need of the population by 2050 even if it exceeds 9 billion. The output of agriculture is expected to increase by 1.7% every year until 2020 (OECD, FAO 2011) which is a major decrease in comparison with the average 2.6% increase of the previous decade. At the same time, the meat, dairy, sugar and vegetable oil consumption is likely to increase by 2020 to a higher extent than so far. Due to the increasing food prices, the amount of starving people will increase and food consumption will decrease – especially in developing countries – as people will be able to buy less and only cheaper food products. Also, obesity may become a more severe problem and the inequality of the population’s health status could increase. One of the most important elements of adapting to global climate change is food safety; therefore, it is especially important to breed new biological bases and to introduce production systems which contribute to adapting to changed circumstances.

The article considers various global factors influencing rural development under the conditions of liberalization of the agricultural land market in Ukraine. The author assesses the impact of global processes and global capital on the development of national farms, income distribution, access to land resources, production processes and equitable development in this country. It is proved that globalization, leading to increased concentration of agri-food production and business and expanding the role of large transnationalized corporations, is primarily aimed at exploiting the country’s existing comparative advantages, rather than increasing them, and promotes, in many recipient countries, a model of double economy split in the technological and socio-economic dimensions into qualitatively heterogeneous sectors. The author concludes that although global factors of agricultural production may have a relatively positive impact in macroeconomic terms, the dominance of multinational (transnational) companies, large exporting companies and financially powerful sovereign welfare funds in the market may create risks and threats of crowding out Ukrainian farmers from the market and blocking the sustainable development of rural areas. At the same time, Ukraine's agricultural sector will be transformed into a raw-material link of global food production chains dominated by large transnationalized entities, and a kind of raw-material enclave of transnationalized production will be created within the Ukrainian economy. The article argues that in today's global economy, where cardinal transformations are taking place and uncertainty is growing, land will become an increasingly valuable asset, attractive not only to agricultural producers but also to land speculators and those who try to maintain the value of their assets under the conditions of growing global risks. Under such conditions, investment in land will not at all necessarily contribute to the development of agricultural production, because speculative capital in the face of widespread expectations of a long and significant upward trend in land prices will prevail over productive agricultural capital. In general, this might lead to a significant increase in the cost of agricultural production and food prices. The author proves that the liberalization of the land market leads to increased risks of transfer of the control over Ukraine’s land resources to foreigners (sovereign financial funds and major international corporations), given their dramatic advantage by available financial resources for land acquisition, compared to those possessed by Ukraine’s residents. The article substantiates a set of policy measures and national policy instruments necessary to minimize the risks associated with the introduction (in the context of globalization) of free purchase and sale of agricultural land, which comply with the regulation principles of the European Union.

AbstractBioenergy is expected to play an important role in the achievement of stringent climate-change mitigation targets requiring the application of negative emissions technology. Using a multi-model framework, we assess the effects of high bioenergy demand on global food production, food security, and competition for agricultural land. Various scenarios simulate global bioenergy demands of 100, 200, 300, and 400 exajoules (EJ) by 2100, with and without a carbon price. Six global energy-economy-agriculture models contribute to this study, with different methodologies and technologies used for bioenergy supply and greenhouse-gas mitigation options for agriculture. We find that the large-scale use of bioenergy, if not implemented properly, would raise food prices and increase the number of people at risk of hunger in many areas of the world. For example, an increase in global bioenergy demand from 200 to 300 EJ causes a − 11% to + 40% change in food crop prices and decreases food consumption from − 45 to − 2 kcal person−1 day−1, leading to an additional 0 to 25 million people at risk of hunger compared with the case of no bioenergy demand (90th percentile range across models). This risk does not rule out the intensive use of bioenergy but shows the importance of its careful implementation, potentially including regulations that protect cropland for food production or for the use of bioenergy feedstock on land that is not competitive with food production.

Global food security is one if the major issues that needs utmost attention of the scientific community in near future. The growing food demand of the society is putting enormous pressure on the resources over which the food supply of the civilization depends. The two major components affecting the global food security are population and global climate change. The rate at which the population of the World is increasing, the food production needs to be doubled to meet the growing requirements. Consequences of global climate change not only reduce the productivity of major staple crops, but also cause destruction of the arable land that can be used for agricultural purposes. The present chapter discusses the effects of population increase and climate change upon food production, which will play a significant role in food security around the globe in near future.

Antibiotic and multi-drug resistant (MDR) Salmonella poses a significant threat to public health due to its ability to colonize animals (cold and warm-blooded) and contaminate freshwater supplies. Monitoring antibiotic resistant Salmonella is traditionally costly, involving the application of phenotypic and genotypic tests over several days. However, with the introduction of cheaper semi-automated devices in the last decade, strain detection and identification times have significantly fallen. This, in turn, has led to efficiently regulated food production systems and further reductions in food safety hazards. This review highlights current and emerging technologies used in the detection of antibiotic resistant and MDR Salmonella.


Degradation currently affects 25 % of the land on Earth and 40 % of the agricultural land on Earth. Environmental effects of soil degradation are widespread, including increased soil losses, deterioration of water quality, decline of biodiversity and degradation of ecological resources and associated values, especially where actual land use is disrespectful (natural use in circumstances where land is in conflict with the environment. Changes in temperature, wind velocity, and precipitation patterns can affect the production of plant biomass, land use, land cover, soil moisture, infiltration rate, runoff and crop management, and eventually land degradation. In recent decades, powerful partnerships have been seen between global climate change and land loss processes. In order to reliably define or forecast the effect of climate change on the loss of land, models of climate change and land use models should be combined with hydrology. Until the first seventies land degradation and geological process weren't thought of a serious issue in most Mediterranean regions. Traditional agricultural systems were believed to be able to keep those processes under control. So low priority was appointed to research programmes and comes on eroding and conservation, preference being given to the impact of farm machinery on soil structure and compaction beside the role of organic matter within the soil. To regulate the destruction of soil, it is therefore important to have limited and global strategies and regulations. Land use and land cover changes influence carbon fluxes and GHGs emissions that directly alter atmospherical composition and radioactive forcing properties. Land degradation aggravates greenhouse gas-induced global climate change through the discharge of CO2 from cleared and dead vegetation and thru the reduction of the carbon sequestration potential of degraded land. The present analysis furnishes effects of climate amendment on land degradation.

The coronavirus disease 2019 (COVID-19), caused by Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has created an opportunity to rethink and rectify the existing loopholes in the global food production system. The continuing ‘illegal’ attacks of human being over the environment for decades has taken a turn back in the form of a novel pandemic virus. This is not the first time we are facing a setback due to our invalid and primitive food habits that has been followed by certain sections of the society in different parts of the globe. Considering the current scenario, it is necessary to update our food habits and food culture as it is the need of the time. Although several studies have proven the persistence of viral particles on the surface materials that are routinely used in the food production systems. Further studies are required to explore the possibilities of SARS-CoV-2 transmission via food and food packaging materials. Although the pandemic has created a bit of awareness among the people, further campaigning is required to achieve an effective food safety system. The strict implementation of FSMS (food safety management systems) such as GMP (Good Manufacturing Practices), HACCP (Hazard Analysis and Critical Control Points) is advised for improving the food supply chain. Besides these, proper cleaning and sanitization, GHP (Good Hygienic Practices), and efficient packaging systems are also necessary to generate wholesome food from farm to fork.
