Irrigation methods in vegetables: Past to future

With water becoming increasingly scarce, climate patterns shifting, and global food demand rising, farmers are under more pressure than ever to use water wisely. To meet these challenges, modern irrigation technologies are stepping in to make agriculture more sustainable. This paper takes a closer look at both traditional and advanced irrigation methods, including flood, furrow, drip, sprinkler, central pivot, micro-sprinkler, and capillary irrigation. It explores how each one works, its benefits, drawbacks, and potential future developments. Central pivot irrigation, for example, is a favourite in large-scale farming thanks to its efficiency and automation, but it comes with high upfront costs and energy demands. Micro-sprinkler systems are great for precision watering in orchards and vegetable farms, though they can be costly and prone to clogging. Capillary irrigation, which includes systems like mats and wicks, is beneficial in greenhouses and small-scale setups, offering efficient water use but limited scalability. The good news is that technologies like the Internet of Things (IoT), artificial intelligence (AI), remote sensing, and Variable Rate Irrigation (VRI) are transforming how these systems operate. Looking ahead, emerging technologies such as predictive analytics, nanotechnology, and blockchain could take water management and irrigation efficiency to the next level. This review emphasises the urgent need for affordable and sustainable irrigation solutions, especially in regions where water is scarce. As global food demand increases and climate challenges intensify, adopting modern irrigation methods is crucial for ensuring food security and developing climate-resilient agriculture. Many of these methods work by delivering water directly to the plant roots through systems of valves, pipes, and emitters.
