Abstract Maize refers to one of the major food crops worldwide. Its yield has a direct effect on global food security. Moreover, cultivated lands in the world have been undergoing serious degradation. In the present study, field experiments were performed in the middle of Jilin, China. A novel maize cultivating method, combining drip irrigation under film mulch cultivation and high photosynthetic efficient cultivation, is presented. NUE, WUE, accumulated temperature, plant growth and yield were determined in high photosynthetic efficient cultivation with drip irrigation under mulch and with there being under the mulch transparent and black film, respectively. As revealed from the results, the high photosynthetic efficient cultivation based on drip irrigation cultivation could increase the yield of rain-fed treatment by 53%; high photosynthetic efficient cultivation with drip irrigation under film mulch cultivation could also improve NUE and WUE compared with conventional drip irrigation under film mulch cultivation; transparent mulch could more significantly raise the soil temperature than black mulching, as well as improving the maize yield. The present study presents a novel planting mode in accordance with reliable theory to sustainably develop maize.

The world is currently experiencing a pandemic: a virus in the family Coronaviridae is causing serious respiratory infections in humans. The outbreak of novel coronavirus disease (COVID-19) was declared a pandemic by the WHO on 11 March 2020. The outbreak began in December 2019 in Wuhan, China, and has since spread throughout the world. Despite measures taken by governments throughout the world to contain and control the spread, economic disruption at the global level is imminent and will affect all economic sectors, particularly the food sector. In a post-pandemic scenario, the use of new technologies will be decisive in a new model of food commercialization. The production and distribution of food will be configured to make supply chains optimal and safe systems. Against this background, the present study aims to explore and analyze the implications of the COVID-19 pandemic for global food security.

The purpose of the article is to investigate the problem of food shortages for a significant number of the population worldwide, taking into account the history of the problem, its causes, consequences, statistics and prospects for solving in accordance with existing trends. Research methods. Methods used: theoretical generalization - for characterizing international organizations and program goals that work to combat hunger, analysis and synthesis - for consideration the dynamics number of starving people on the planet and identify regions and countries with largest expanding such problem, comparative evaluation - for comparing absolute and relative statistical indicators in various aspects of the problem, historical - for structuring over time the measures taken to ensure sufficient food supply and their actual results, graphic - for better visualization the comparative statistics. Research results. Information on the responsible institutions that settle food shortages around the world is provided, key issues that need attention in the context of food insecurity are described, quantitative indicators of the global food problem are considered, the uneven nature of its distribution is highlighted, given list of the factors that deepen social and economic problems for the population, a clear link between poverty and chronic malnutrition is determined, critical remarks about the reality of prospect to overcome hunger according to the planned schedule are formed. Scientific novelty. An assessment of development the situation with the number of starving people in the world in the coming decades is made, taking into account an expected demographic changes and potential resources of agricultural production as a key sector in this problem. Practical significance. The provisions of the article are aimed at underlining weaknesses in the global food security system, detailing them and presenting to domestic authorities and business structures in order to find a balance between expanding export potential, participating in international initiatives and maintaining economical-effective agricultural sector.

Mexico is hosting the 13th Conference of the Parts (COP-13) on the Convention on Biological Diversity. Participants will have another opportunity to "integrate biodiversity for wellbeing." Considering that food production is a major driver for the loss of biological diversity, despite the fact that ample genetic reservoirs are crucial for the persistence of agriculture in a changing world, food can be a conduit for bringing biodiversity into people's minds and government agendas. If this generation is going to "live in harmony with nature," as the Aichi Biodiversity Targets indicate, such an integration needs to be developed between the agricultural and environmental sectors throughout the world, especially as an increasingly urban civilization severs its cultural connections to food origin.

A comprehensive assessment of national food security should include an analysis of the physical and economic accessibility of food, the level and quality of nutrition of the population, the sustainability and competitiveness of agriculture, factors and trends of self-sufficiency in the main types of agricultural products, raw materials and food and the effectiveness of foreign trade in food. To assess the food security situation at the state level, it is necessary to conduct monitoring, which consists in determining the deviations of the main indicators from the criteria and thresholds established at the national level. The monitoring should determine the format of the national report on the country's food security. The number of indicators that make up its basis, should be optimal and sufficient to reflect the level of food security of the country and compare them with the situation in other countries. At the same time, it is necessary to analyze trends in ensuring food security at the global level in terms of the progress of countries and regions of the world in achieving the goals of sustainable development in agriculture, the elimination of hunger and poverty for the period up to 2030.  Conducting a study of the components of the global food security index, formed at the world level to measure the policy and efficiency of government agencies in the field of food security, is relevant and in demand for positioning the country within the framework of international comparison of countries.

The article examines the impact of the coronavirus pandemic on the world food system (WFS) through the prism of economic and social aspects. It is revealed that the paralysis of world trade caused by the coronavirus pandemic has had a devastating effect on the WFS and threatens global food security. It is proved that in order to prevent a food crisis in the foreseeable future, it is necessary to restructure food systems at the national and global levels, ensure their stability and continuity of operation. Some measures are proposed to prevent trade barriers, protect food supply chains and expand access to food. It is concluded that there is a need to expand domestic «food sovereignty», especially in countries that depend on agricultural imports and are involved in the global food trade system.

Sustainable development of saline water irrigation was restricted in HID (Hetao Irrigation District) by serious yield reduction and severe salt accumulation without an effective irrigation schedule. Field experiments were carried out to study the effects of drip irrigation thresholds on soil salt transportation and maize yield with shallow saline ground water in 2015 and 2016 in HID. The irrigation was triggered by four soil matric potential (SMP) treatments which measured 20 cm beneath the drip emitter. Results indicate that the shape of the wetting body approximated a one-fourth ellipse on the vertical profile perpendicular to the drip line, while the horizontal radius increased with the increase of SMP. Moreover, salt accumulation decreased with the increasing thresholds in the 0–40-cm layer, while the soil salt in the 40–100 cm layer was hardly affected by SMP thresholds under a drip irrigation quota of 22.5 mm. Maize yield showed a quadratic relationship with the SMP threshold, and the irrigation water use efficiency (IWUE) showed a linear increase in response to the decrease in SMP threshold. Taking into account the salt accumulation, yield and IWUE, a SMP threshold higher than −30 kPa is suggested as the appropriate indicator for maize mulched-drip irrigation with shallow saline groundwater in HID.
