The data documented the spatiotemporal anthropogenic pressures on reach-scale rivers across South and Southeast Asia from 1990-2014. The data used to produce the results reported in the manuscript "Changes to anthropogenic pressures on reach-scale rivers in South and Southeast Asia from 1990 to 2014". The attributes of the data are explained as follows: (1) "lengthkm": the length (km) of the river reach. (2) "order": stream order of the river reach, from Lin et al. (2019). (3) "nnCCI92": the anthropogenic pressures induced by irrigation in 1992. (4) "nnCCI00": the anthropogenic pressures induced by irrigation in 2000. (5) "nnCCI14": the anthropogenic pressures induced by irrigation in 2014. (6) "nnGHSL90": the anthropogenic pressures induced by human usage in 1990. (7) "nnGHSL00": the anthropogenic pressures induced by human usage in 2000. (8) "nnGHSL14": the anthropogenic pressures induced by human usage in 2014. (9) "sum90": the total anthropogenic pressures on river reaches in 1990. (10) "sum00": the total anthropogenic pressures on river reaches in 2000. (11) "sum14": the total anthropogenic pressures on river reaches in 2014. (12) "sum9014": the average anthropogenic pressures on river reaches from 1990-2014.
