Genetically modified crops: An overview

Abstract

Global demand for food is increasing with the growing world population and decreasing arable land. Food and agricultural systems have to respond to several changes with increasing international competition, globalization and rising consumer demands for improved food quality, safety, health enhancement and convenience. Modern biotechnology involving the use of RDNA technology/genetic engineering emerged as a powerful tool for improving the quantity and quality of food supply. Available worldwide with aim of enhancing productivity, decreasing the use of certain agricultural chemicals, modifying the inherent properties of crops, improving the nutritional value or even increasing shelf life. Concerns about the potential risks associated with their impact to human health, environment and biological diversity.
