Population explosion and the need to provide food for humankind and to increase the quality and quantity of food products in order to ensure food security with regard to its managerial, environmental, and developmental aspects has led to the use of new agriculture methods and technologies. Today, different approaches, such as plant breeding, genetically modified foods, in vitro planting, and the spread of closed ecological systems, are applied as a solution to increase food accessibility. In addition to these methods, using modern technologies under the title of precision agriculture have been proposed as ways to achieve food security. Early intervention to prevent the occurrence of unwanted events with the ability to monitor crops in all stages of production, from tillage to post harvest, are provided by using various methods, such as remote sensing and geographic information systems. In addition to the economic and environmental impacts of precision agriculture, expanding farmers' awareness through the use of modern technologies and the integration of scattered lands to achieve sustainability are known as social impacts of precision agriculture. In this manuscript we have tried to summarize the different methods of precision agriculture that could affect food security in its multiple branches.

One important goal of precision horticulture (PH), as well as precision agriculture (PA), is to measure and manage spatial and temporal variation in orchards. In this study, temporal and spatial analysis of yields were carried out over 2 years for a 0.5-ha apple orchard (at the Haymana Research Station of Ankara University, Turkey, from 2017 to 2018) to determine the variability of yields over time and included seven apple varieties: ‘Royal Gala’, ‘Red Chief’, ‘Braeburn’, ‘Mondial Gala’, ‘Jonagold’, ‘Fuji’, and ‘Mitch Gala’. To achieve this, yield data for two different years were analyzed for mean yield, temporal variance, and cv in terms of spatial and temporal stability, and their yield maps were produced. The results showed that ‘Jonagold’, ‘Braeburn’, and ‘Red Chief’ varieties yielded less than the average yield, whereas the other varieties produced average yields when the yield from 2 years was taken into account. Calculation of the values for determining temporal stability over time resulted in all existing varieties being identified as stable over time. For example, the ‘Jonagold’ and ‘Red Chief’ varieties showed 100% stability in terms of temporal variance. Results also showed that the ‘Gala’ varieties were stable for 2 years and produced high yields, whereas the other varieties were specified as stable and low yielding when spatial and temporal variability was considered in combination.
