Agricultural Technology and Food Security

Introduction

Agriculture is the backbone of the global economy and a primary source of food, livelihood, and raw materials. With the world population continuously increasing, ensuring food security has become a major challenge. Agricultural technology, also called AgriTech, refers to the use of modern tools, machinery, information systems, biotechnology, and innovative practices to enhance farm productivity, efficiency, and sustainability.

Food security is defined by the United Nations’ FAO as a condition where all people have physical, social, and economic access to sufficient, safe, and nutritious food to meet their dietary needs for an active and healthy life.

This post explores the importance, challenges, technological innovations, sustainable practices, and global strategies in agricultural technology and food security.
