Emerging technologies in precision weed management: Tools, techniques, and the future of agriculture

Abstract

In recent decades, the global population surge has created a demand for increased food production, placing greater stress on agricultural systems. Challenges such as climate change, water scarcity, and diminishing arable land further jeopardize the sustainability of farming. Weeds pose a significant threat to food production by competing for natural resources, thereby diminishing product quality and productivity in agricultural systems. To ensure effective and sustainable weed management, a balanced integration of various control methods (cultural, mechanical, and chemical) is essential, avoiding excessive mechanization and herbicide usage to prevent harm to the overall agrarian ecosystem. Conversely, advancements in weed control technologies offer opportunities for increased food production, reduced input requirements, and minimized environmental impact, ultimately moving us closer to more sustainable agricultural practices like precision farming. This chapter comprehensively examines the limitations of both traditional and innovative methods for weed control, as well as the development of tools and constraints associated with precision weed management, all analyzed through a sustainability lens.
