  abstract = {{A} protocol for characterizing patterns of rice cropping practices and injuries due to pathogens, insects, and weeds was developed and used in six sites in tropical {A}sia covering a wide range of environments where lowland rice is cultivated. {T}he data collected in a total population of 456 individual farmers' fields were combined to site-specific weather data and analyzed using non-parametric multivariate techniques : cluster analyses with chi-square distance and correspondence analyses. {T}he main results are : (1) patterns of cropping practices that are common across sites can be identified ; (ii) conversely, injury profiles that are common across sites can be determined ; (iii) patterns of cropping practices and injury profiles are strongly associated at the regional scale ; (iv) weather patterns are strongly associated with patterns of cropping practices and injury profiles ; (v) patterns of cropping practices and injury profiles allow for a good description of the variation in actual yield ; and (vi) patterns of cropping practices and injury profiles allow for a good description of the variation in actual yeild; and (vi) patterns of cropping practices and injury profiles provide a framework that accurately reflects weather variation and site diversity, and reliably accounts for variation in yield. {T}he mean estimated yield across sites (4.12 t/ha) corresponds to commonly cited averages in the region and indicates the potential for increased productivity with better management practices, especially an improved water supply. {I}njuries due to pests are secondary compared with other yield-limiting factors. {I}njury profiles were dominated by stem rot and sheath blight ({IN}1) ; bacterial leaf blight, plant hoppers, and leaf folder ({IN}2) ; and sheath rot, brown spot, leaf blast, and neck blast ({IN}3)...
