The environmental challenges within drylands to providing sustainable water, food, and energy for an increased population test the capacity of integrated science to represent, apply, and project our knowledge to future forecasts. Scientists in this discipline need to provide (i) quantitative understanding of natural resources (land and water), their characteristics, and their interactions within the soil-water-plant-atmosphere continuum; (ii) the valuation of primary resources and their use for food production; and (iii) knowledge for the building of a translational framework between the scientific and the policymaking communities to advise policymakers how to better manage these resources. The use/reuse of two potential water resources can play pivotal roles in improving water and food security in drylands; once potential challenges and gaps in physical water accounting and characterization are addressed, new water and green water can be a part of future water and food policymaking and bridge the ever increasing water–food demands in drylands.

Green water is defined as the water in soil that is potentially available to plants for uptake and subsequent transpiration. Despite the fact that crop biomass is directly related to transpiration and the global transpiration flow alone matches that of all the rivers in the world, green water has until recently been largely neglected in research on food security. That long neglect is redressed by a review of recent research on the role of green water in the production of agricultural commodities to meet current and future world food demand, including how the differences in water requirement between plant-based and animal-based commodities play out in respect to the food-water nexus. Informed by current literature, a case is made for optimizing green water management to achieve a global increase in food production from 20 to 40 percent without an expansion of either agricultural land use or the volume of water withdrawn for irrigation.

Relevance. Grain is the key to strategic products to ensure food security. From this point of view, the creation of large grain farms is a matter for the country's selfsufficiency and it leading to a decrease in financial expense for import. Creation of such farms creates an abundance of productivity from the area and leads to obtaining increased reproductive seeds. The main policy of the government is to minimize dependency from import, create abundance of food and create favorable conditions for export potential.The purpose of the study: the development of grain production in order to ensure food security of the country and strengthen government support for this industry.Methods: comparative analysis, systems approach.Results. As shown in the research, if we pay attention to the activities of private entrepreneurship in the country, we can see result of the implementation of agrarian reforms after which various types of farms have been created in republic.The role of privateentrepreneurshipinthedevelopmentofproduction is great. Тhe article outlines the sowing area, production, productivity, import, export of grain and the level of selfsufficiency in this country from 2015 till 2017.

Food insecurity in Indigenous communities in Canada continue to gain increasing attention among scholars, community practitioners, and policy makers. Meanwhile, the role and importance of Indigenous foods, associated knowledges, and perspectives of Indigenous peoples (Council of Canadian Academies, 2014) that highlight community voices in food security still remain under-represented and under-studied in this discourse. University of Winnipeg (UW) researchers and Fisher River Cree Nation (FRCN) representatives began an action research partnership to explore Indigenous knowledges associated with food cultivation, production, and consumption practices within the community since 2012. The participatory, place-based, and collaborative case study involved 17 oral history interviews with knowledge keepers of FRCN. The goal was to understand their perspectives of and challenges to community food security, and to explore the potential role of Indigenous food knowledges in meeting community food security needs. In particular, the role of land-based Indigenous foods in meeting community food security through restoration of health, cultural values, identity, and self-determination were emphasized by the knowledge keepers—a vision that supports Indigenous food sovereignty. The restorative potential of Indigenous food sovereignty in empowering individuals and communities is well-acknowledged. It can nurture sacred relationships and actions to renew and strengthen relationships to the community’s own Indigenous land-based foods, previously weakened by colonialism, globalization, and neoliberal policies.
