Globally, agriculture is a cornerstone of food security and livelihoods – roughly 26% of the world's workforce is employed in farming – yet plant diseases inflict massive losses. Humans get 80% of their food from plants, but up to 40% of global crop production is destroyed by pests and pathogens each year, costing on the order of USD 220 billion annually.

In India, where agriculture remains a rural backbone, recent data show about 42.3% of the population depends on farming (and roughly two-thirds of rural Indians derive their livelihood from agriculture). Crop diseases commonly cut Indian crop output by 10–30%, with some analyses even citing 30% annual productivity loss due to pest infestations. Such declines are especially harmful for millions of smallholder farmers, where even modest yield drops can undermine income and food access.

Moreover, climate change and modern farming amplify these threats: warming allows pathogens (like fungi) to spread into new regions, and large-scale monocultures of genetically uniform crops provide ideal breeding grounds for outbreaks.

In this context, early disease detection is vitally important. AI and machine-learning tools can rapidly scan plant images or sensor data to diagnose infections before they become widespread. By providing fast, precise, and automated diagnostics, these technologies cut labor and response time and enable targeted interventions—spot-treating only infected areas.

In practice, AI-driven monitoring helps farmers act quickly, quarantining or treating diseased plants in time, thereby minimizing crop loss and strengthening food security. Given agriculture's socio-economic importance (especially in India) and the growing strain of disease pressures, timely plant disease detection through AI/ML methods is critical to reduce losses, sustain yields, and support rural livelihoods.
