Food irradiation and its role in improving the safety and security of food

Food security depends on available world supplies of food, the income of the designated population, and the population's access to the available supplies. Consequently, though seldom recognized in national food security policies, there is a direct relationship between food security, world trade in food, and the domestic policies that govern access to international markets for food. On all three scores, I believe we can be optimistic about improvements in world food security over the next quarter century. Over the next quarter century, the world's supply of food will grow somewhat more rapidly than will the demand for it, leading to lower real prices of food. Thus, the trend of food prices, as measured by grain prices, is likely to continue the trend of the current century, though at a slower rate of decline.' The remarkable reduction in the international price of grain that has occurred in this century is given all too little emphasis in discussions of the world food situation, certainly so in the discussions of the food pessimists. I am confident that the real per capita incomes of the majority of the population in the developing countries will continue to increase, contributing to an improvement in food security. Finally, I believe that, with the changes in agricultural policies in the major industrial countries, world trade in farm products, especially grains, will be further liberalized in the future. In addition, more and more developing countries are reducing barriers to trade, thus increasing access to world food supplies. Thus, all the broad trends point o an improvement in world food security and a reduction in the number of persons adversely affected by both long-term or short-term inadequate access to food. This does not mean that in every country food security will improve. Some governments may continue to follow national and trade policies related to food that restrict domestic food production, limit the growth of per capita incomes, and restrict access to the available world food supplies. When this happens, food security and adequacy will not be im roved or not improved as much as they po entially could be. At this time, there can be little doubt that the poor performance of agriculture and the insecurity of food supplies in sub-Saharan Africa over the past quarter century have been due primarily to inappropriate policies-to policies that discriminated against agriculture and resulted in large-scale governmental interventions in international trade. Misgovernment plus civil and ethnic wars have exacted and continue to exact a

Irradiation of food

9 - World Distribution in Relation to Economic Losses

A third of all food produced globally by weight is lost or wasted between farm and fork – that's more than 1 billion tonnes. Converted into calories, this equates to 24% of the world's food supplies. Food loss refers to loss at or near the farm and in the supply chain. For the present study, it is important to know the losses of agricultural products that occur between the level at which production is recorded and the household, i.e., storage and transportation. The prevalence of overweight and obesity is emerging as a problem in Bulgarian society as well. Revealing the relationship between food loss from agricultural products and the prevalence of obesity is the aim of the study. The data source is the Food and Agriculture Organization (FAO). Data from Food Balances and from Food Security and Nutrition were used. The data refer to the period 2000–2021. For per capita supply, all four FAO indicators were used: Food supply quantity (kg/capita/year), Food supply (kcal/capita/day), Protein supply quantity (g/capita/day), Fat supply quantity (g/capita/day), separately for vegetal and animal products. One indicator was used as a measure of population nutrition: Prevalence of obesity in the adult population (18 years and older). For the last indicator, there is data only for the period 2000–2016, so our analysis is limited to this period. The main hypothesis is that food losses affect the per capita supply, which in turn affects the nutrition of the population and the prevalence of obesity. A simultaneous equations model (SEM) was used to model these relationships and process data. After evaluation of the SEM model, the following results were obtained: Losses of vegetal products directly influence the prevalence of obesity in the adult population (18 years and older). The relationship is negative – greater losses of vegetal products lead to a lower prevalence of obesity in the adult population (18 years and older), which coincides with preliminary expectations. Losses of animal products indirectly influence the prevalence of obesity in the adult population (18 years and older). The relationship is mediated by food supply (kcal/capita/day). The relationship between losses of animal products and the mediator variable is positive; greater losses lead to greater per capita supply. This contradicts preliminary expectations that greater losses will lead to a smaller per capita supply. The relationship between per capita supply and the prevalence of obesity in the adult population (18 years and older) is positive; larger per capita supply leads to a higher prevalence of obesity in the adult population, which coincides with preliminary expectations. Some of the mediator variables have an independent influence on the dependent variables.

At the current stage, food security is one of the main aspects of ensuring national and global security. This is explained by the fact that ensuring the consumption and access to the consumption of food is the foundation of the formation of a high level of quality of life. Russia's aggression against Ukraine clearly indicated the vulnerability and dependence of the national and global food systems on various factors: armed conflicts and as a result rising food prices, crop shortages due to disruption of the ecosystem due to military actions, disruption of global food supply chains. Domestic scientists dealt with the problem of food security considers the main dimensions of food security. In the modern conditions of Russia's aggression against Ukraine, considerable attention is paid to the analysis of Ukraine's food security during the war. Food security directly affects such important national and economic interests that determine the future of the country, its well-being and the prosperity of the people of Ukraine. Ukraine occupies one of the main positions in the system of ensuring global food security due to the active export of food. The main articles of Ukrainian food exports are products of vegetable origin – the average specific weight of 24.83% and fats and oils of vegetable origin with the average specific weight of 10.88%. Other articles of food export are insignificant. Ukraine provides its population with food independently, which is evidenced by a constant positive balance and a significant coverage ratio. At the same time, Ukraine was threatened by significant dependence on food exports. Subsequent events confirmed these threats. After the start of Russia's aggression against Ukraine, the world faced a threat to global food security. The article pays considerable attention to the place of Ukrainian food exports in the system of global food security. After the start of Russia's aggression against Ukraine, the world faced a threatworld food security. To ensure the world's food supply security measures are proposed at the national and international level.Onat the national level, it is proposed to: meet the work needs of countries with providing the population with long-term storage food in regions where Fierce military actions are taking place, the formation of a guarantee storage network withsafe movement of ships involved in the shipment of grain and food products from national ports.

omega-Atracotoxin-Hv1a is an insect-specific neurotoxin whose phylogenetic specificity derives from its ability to antagonize insect, but not vertebrate, voltage-gated calcium channels. In order to help understand its mechanism of action and to enhance its utility as a lead compound for insecticide development, we used a combination of protein engineering and site-directed mutagenesis to probe the toxin for key functional regions. First, we constructed a Hairpinless mutant in which the C-terminal beta-hairpin, which is highly conserved in this family of neurotoxins, was excised without affecting the fold of the residual disulfide-rich core of the toxin. The Hairpinless mutant was devoid of insecticidal activity, indicating the functional importance of the hairpin. We subsequently developed a highly efficient system for production of recombinant toxin and then probed the hairpin for key functional residues using alanine-scanning mutagenesis followed by a second round of mutagenesis based on initial "hits" from the alanine scan. This revealed that two spatially proximal residues, Asn(27) and Arg(35), form a contiguous molecular surface that is essential for toxin activity. We propose that this surface of the beta-hairpin is a key site for interaction of the toxin with insect calcium channels.

Rift grows in GM debate

After decades of steady growth, the world's food supply is no longer keeping up with population increases. Production of fish and grain per person has slowed to the point where feeding the 90 million being added each year is possible only by reducing consumption among those already here. These are the findings in this fourth volume in the Worldwatch Environmental Alert series from the Worldwatch Institute. The bottom line, according to Lester Brown and Hal Kane, is that the world's farmers can no longer be counted on to feed adequately the projected additions to our numbers. Achieving a humane balance between food and people now depends more on family planners than on farmers. This issue will increasingly preoccupy national leaders, reorder national priorities, and dominate international affairs. In this volume, the authors propose a global strategy to restore food security and a budget to implement it. Their global food security budget calls for stepped-up expenditures on both sides of the food/population equation. It includes investments not only to provide family planning services to all who want them, but also to eliminate the underlying causes of high fertility, such as female illiteracy. It also includes investments in an extensive reforestation and soil conservation effort, one that will arrest the deterioration of the agricultural resource base.

This review looks at how Indian agriculture and adaptation tactics are affected by climate change. Due to human activity, climate change is causing problems including extreme weather occurrences and rising temperatures. Increased temperatures have the potential to cause heat stress in crops, which lowers yields and results in lower-quality produce. Farmers employ climate-resilient crop development and planting date adjustments as adaptation strategies. Variable or irregular rainfall patterns can lead to drought conditions, which can dry out farmlands and result in crop failures. However, floods brought on by too much rain can harm crops and soil and cause disruptions to agricultural activities, particularly during the monsoon season. Initiatives for precision farming, urban food production, and soil conservation all support resource recycling and food security. Efficient water management and better irrigation are necessary to address water scarcity. The number of agricultural pests is impacted by climate change, endangering the world's food supply. Numerous adaptation tactics are used, such as socioeconomic initiatives, resource-conservation technologies, and traditional behaviours. Precision farming and other climate-smart agricultural technology boost resilience and yields. Regional appropriateness, economic feasibility, and group execution are all necessary for success. Agriculture is subject to climatic, economic, and policy risks in a complex socio-ecological system. Climate-smart agriculture methods that are site-specific are essential for the resilience and food security of smallholders. Adoption of these technologies can be aided by publicly offered agricultural extension services, but obstacles like budgetary limitations and cultural considerations need to be taken into account. This assessment highlights the necessity of comprehensive, context-specific strategies to address climate change vulnerabilities in Indian agriculture and guarantee a sustainable future for smallholder livelihoods and food production.

The Recombinant DNA (rDNA) technique is expected to bring about a great progress in the improvement of breeding technology and the development of new plant varieties showing high quality and high yield, such as those with excellent pest and disease resistances, those with environmental stress tolerance, etc. In the USA, a late ripening tomato variety (FLAVR SAVRTM) developed through the rDNA technology was commercialized as the world's first recombinant food in 1994. Seven transgenic crop plants, such as herbicide tolerant soybean and canola, insect resistant corn and potato, were complied the all safety assessments with the guidelines required and they are marketable in Japan.General public, however, are not familiar with rDNA technology, and some seem to feel uncomfortable with biotechnology. It is caused by the difficulty of the technology and lacking of sufficient information. In order to promote agricultural biotechnology, it is important to give precise information about rDNA technology to general public so that they can comfortably accept biotechnology and the products. Because, the rDNA technique is an most important technology to improve world's food supply and global environment in the next century.
