Drift waves are a dominant mechanism for particle, energy, and momentum transport across magnetic field lines in magnetized plasmas. This review discusses the current understanding of drift-wave transport, including its role in plasma confinement experiments, theoretical descriptions, and simulations. Drift waves arise from density, temperature, and trapped particle gradients, and their transport properties are influenced by sheared flows and magnetic shear. The review covers the mechanisms of drift-wave generation, their turbulent behavior, and the associated transport phenomena. It also discusses the nonlinear dynamics of drift waves, including the formation of vortices and the role of resistive effects. Theoretical frameworks such as weak turbulence theory, Kolmogorov anisotropic spectral indices, and mixing length are used to describe drift-wave turbulence. The review highlights the importance of drift waves in plasma confinement, particularly in tokamaks and other magnetic confinement devices, and their impact on transport in different regimes of plasma collisionality and geometry. The study also addresses the experimental observations of drift waves in laboratory settings, including the identification of drift-wave structures and their characteristics. The review concludes with the significance of drift waves in understanding and controlling plasma transport in fusion energy research.Drift waves are a dominant mechanism for particle, energy, and momentum transport across magnetic field lines in magnetized plasmas.
