Agriculture is one of the largest water-consuming industries globally, accounting for approximately 70% of global freshwater use. However, many regions across the world are grappling with water scarcity, climate change, and erratic rainfall patterns. As a result, farmers face numerous challenges to ensure sufficient crop yields while minimizing water usage, reducing labor inputs, and improving overall profitability and sustainability. Fortunately, smart irrigation systems are playing an essential role in mitigating these challenges. In this article, we explore how smart irrigation systems increase efficiency and reduce losses in agriculture.
