This work investigates the transmission dynamics of a proposed fractional-order cotton leaf curl virus (CLCuV) model considering effects climate change. High temperatures resulting from change and global warming significantly impact crop CLCuV transmission, causing substantial economic losses for farmers agricultural industries. The study aims to address these impacts contribute Sustainable Development Goals (SDGs) by promoting well-being healthy lives. characteristics model's solution are examined, including equilibrium points basic reproduction number. stability is analyzed in relation key parameters, sensitivity analysis controllable parameters performed. Additionally, optimal management strategies controlling spread explored, aiming minimal cost, improved health, reduced hazards. Numerical simulations conducted validate theoretical findings.
