Abstract
Over the past few decades, climate change has spurred significant changes in the weed flora within the arable biosphere of India. This impact is not direct but rather indirect, as climate change compels adaptations in agronomic practices. For successful strategies in weed control while maximizing crop yield, it is crucial to possess a comprehensive understanding of these transformative processes. Growing concerns revolve around the potential impacts of global CO2 enrichment in weeds and crop yields. Due to the impacts of climate change, there is a probable alteration in life cycles, phenology and infestation pressure. Certain weed species may be at risk of extinction, whereas others might exhibit increased aggressiveness as invaders. Comprehensive studies are of vital importance to assess the collective interactive effects of climate change factors. Such research will aid in predicting how weed-related challenges may evolve within the context of a changing climate scenario.
