Peatland surface subsidence has long been used as a measure of carbon loss throughout the world. There are questions, however, on whether the method is always applied appropriately. In this paper, we show that it is necessary to measure over long periods and at a large number of locations to obtain meaningful results. Applying the most thorough protocol, subsidence rates in an around oil palm plantations in Jambi, Indonesia, are found to be quite constant at rates around 5 cm y-1. This number applies both to young and mature plantations, at water table depths around 0.6 m on average.
