After a review of more or less systematic approaches for normal as well as anomalous particle transport phenomena across a magnetic field, simplified macroscopic models are discussed. A reduced two‐field model for collision‐dominated low‐temperature plasmas is presented. Although it looks similar to its high‐temperature analogue (known as the Hasegawa‐Wakatani equations), it has significant peculiarities which are discussed in detail. Some basic results following from the reduced two‐field model, e.g. anomalous transport scaling close to the onset of collisional driftwave instability, are discussed.
