A city’s potential for food self-sufficiency is expected to increase through the distribution of innovative, high-tech, green agricultural practices of producing food in an urban environment, which can improve the city’s food security due to increased food accessibility in terms of quantity and quality. Aim. Based on the systematization of theoretical approaches and analysis of institutional aspects, the study aims to propose ways to strengthen the city’s food security by improving food supply in urban areas, increasing the socio-economic and environmental sustainability of urban food systems, and changing the diet of urban residents.Tasks. The authors propose methods for the development of urban agricultural production in a large industrial city based on the principles of green economy and outline the range of strategic urban activities aimed at implementing green agricultural production technologies associated with the formation and development of the culture of modern urban agricultural production.Methods. This study uses general scientific methods of cognition to examine the specificity of objectives of strengthening a city’s food security by improving the quality of food supply to the population. Methods of comparison, systems analysis, systematization of information, and the monographic method are also applied.Results. A strategic project for the development of urban agricultural systems through the implementation and green development of advanced urban agricultural technologies is described. Green development mechanisms will create conditions for the city’s self-sufficiency in terms of organic and safe products, functioning of short supply chains, and green urban agriculture.Conclusions. Managing the growth of urban agriculture will promote the use of highly effective, easily controlled, resource-efficient, eco-friendly, weather- and season-independent, multi-format urban agricultural technologies. The study describes actions aimed at creating conditions for stabilizing a city’s high-quality food self-sufficiency with allowance for the growing differentiation of citizen needs.

Ecosystem services (ESs) is a term used to describe the foundations of the well-being of human society, and several relevant studies have been carried out in this area. However, given the fact that the complex trade-offs/synergy relationships of ESs are a challenging area, studies on matching mechanisms for ES supply and demand are still rare. In this study, using the InVEST model, ArcGIS, and other professional tools, we first mapped and quantitatively evaluated the supply and demand of five ES types (water yield, soil conservation, carbon retention, food supply, and leisure and entertainment) in Hangzhou, China, based on land use, meteorology, soil, and socio-economic data. Then, we analyzed the matching characteristics between the supply and demand of these ESs and analyzed the complex trade-offs and synergy between the supply and demand of ESs and factors affecting ESs. The results of this analysis indicate that although the ES supply and demand of carbon retention tended to be out of balance (supply was less than demand), the supply and demand of the other four ES types (i.e., water yield, soil conservation, food supply, and leisure and entertainment) were in balance (supply exceeded demand). Finally, the spatial heterogeneity of the supply and demand of ESs in Hangzhou was significant, especially in urban areas in the northeast and mountainous areas in the southwest. The supply of ESs was based on trade-offs, whereas the demand of ESs was based on synergy. Our results further show that the supply and demand of ESs in the urban area in Hangzhou were out of balance, whereas the supply and demand of ESs in the western region were coordinated. Therefore, the linkage of ES flows between this urban area and the western region should be strengthened. This innovative study could provide useful information for regional land use planning and environmental protection.

Abstract Aquaculture is currently one of the most rapidly growing food production industries in the world. The increasing global importance for this industry stems primarily from the fact that it is reducing the gap between the supply and demand for fish products. Commercial aquaculture contributes significantly to the economies of many countries since high-value fish species are a major source of foreign exchange. This review looks at the aquaculture industry, the issues raised by the production of fish through aquaculture for food security, the sustainability of the practice to agriculture, what the future holds for the industry in the next 10-20 years, and why there is a need to have available analytical procedures to regulate the safe use of chemicals and veterinary drugs in aquaculture.

Liberia's 14 year civil war destroyed domestic agricultural production, veterinary and agricultural education, extension services and domestic food security. These losses severely limited domestic food production, and basic hygiene and sanitation: potable water, abattoirs, cold chain and food storage were greatly diminished. The average Liberian life expectancy fell from 45.8 in 1990 to 41.8 years presently. The population birth and death rate are two of the highest globally with a resulting population growth rate, of 2.7% per annum; this growth rate requires an immediate and concerted focus on domestic food production to alleviate nutritional inadequacy and hunger, trade imbalances and loss of foreign exchange credits. Food supply nationally is presumed adequate because of importation, though domestic production is inadequate. Unequal distribution precludes food security for all Liberians. Value chain augmentation, enhancing food availability across all sectors of Liberian society and ensuring distribution of a safe food supply needs critical development. Infant mortality remains one of the highest in the world (approximately 160/1000 births), much of which is attributed to food insecurity, food contamination and lack of uniformly available potable water. Recreation of Liberia's public health and food security requires redevelopment of disease monitoring and laboratory diagnostic capability to re-establish safe food production and handling practices across all sectors. This will allow determination of endemic disease burden for the principal livestock species: poultry, sheep, goats, cattle and swine. Creation of a national disease surveillance/monitoring system allows for targeted disease intervention, ensuring vaccination for correct serotypes and most critically prevalent diseases. Creation of community level training and support will target intervention of local diseases, but also allow for national prioritization of diseases. Targeting which are most prevalent or most likely to cause production limiting effects will require periodic surveillance, targeted vaccination, and chemotherapeutic intervention and evaluation of therapeutic success.

Abstract Background On an individual level, food security has multiple dimensions and consumers exhibit heterogeneity in the extent to which different attributes matter in their quest for enhanced food security. The aim of this paper is to explain how the quest for individual food security arises and its dynamic nature and its implications for how food security-enhancing attributes are defined and how they are signaled, and for the role of regulators and food supply chains in establishing credible signals. Results The paper finds that the quest for enhanced individual food security is a dynamic process that responds to the disequilibrium that change brings. The changing role of standards and grades as signals in food markets is discussed as a precursor to considering the implications for both market and non-market (regulatory) failure in determining the appropriate role for the public sector in regulating food safety and quality standards and labeling. The rise of private standards is examined, along with a consideration of how these standards differ in terms of scope and objective and their implications for international trade in increasingly globalized food supply chains. Conclusions Despite the growth of private standards, a clear role remains for mandatory public standards, yet challenges arise when these standards differ across countries.

Across the world, the COVID-19 pandemic has disrupted food supply chains and threatened food security. Singapore is highly dependent on food imports and has an open economy that exposes it to volatile global markets, so it is acutely vulnerable to the effects of the pandemic on other countries, the effectiveness of measures taken by foreign governments to combat the spread of the virus and overall disruptions of international trade links. Proactive and reactive steps have been taken to protect Singapore's food supply chains against the adverse impacts of COVID-19. In this paper, we discuss food security in the city state, the impacts of COVID-19 in the population, the local production, and imports from two main trade partners: Malaysia and China. We conclude by acknowledging the complexity of achieving food security under the very difficult circumstances.
