Suitability map for AWD in the wet season.

<p>Map shows the pixels identified as suitable for AWD in the wet season based on soil specific percolation rates (using the basic settings column in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0145268#pone.0145268.t004" target="_blank">Table 4</a>) and for suitability class breakpoints (using the basic settings row in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0145268#pone.0145268.t005" target="_blank">Table 5</a>).</p

10 year mean rainfall in mm/dekad.

<p>Top left panel shows the rice extent map as a reference, then sequentially from left to right, top to bottom the remaining 37 panels show the spatial distribution of the 10 year mean daily rainfall per dekad. The border of each rainfall map shows if the dekad is in the dry season (red), wet season (blue) or off-season (gray).</p

The Philippines and key spatial datasets for Cagayan province.

<p>Panel A: The Philippines, with Cagayan province highlighted. Panel B: Extent of the rice growing area in Cagayan province: Panel C: Soil Mapping Units (SMU) in Cagayan province derived from the Harmonized World Soil Database (HWSD).</p

Sensitivity analysis on Pot_Pc for AWD in the wet season.

<p>Area of wet season rice (in hectares) deemed climatically suitable for AWD, by suitability class. The basic setting breakpoints were used for the suitability classes and each bar in the chart represents the suitable area for different Pot_Pc setting in the soil specific Pot_Pc rates (top panel) and fixed Pot_Pc rates (bottom panel).</p

10 year mean Pot_ET in mm/dekad.

<p>Top left panel shows the rice extent map as a reference, then sequentially from left to right, top to bottom the remaining 37 panels show the spatial distribution of the 10 year mean Pot_ET per dekad. The border of each Pot_ET map shows if the dekad is in the dry season (red, wet season (blue) or off-season (gray).</p

Schematic display of the water balance in flooded rice fields without irrigation (redrawn with modifications after [32]).

<p>Blue (thick) arrows in the figure are the only water fluxes considered in the water balance calculations. Black arrows show other water flows that are not considered.</p

<p>a,b,c,d,e,f. Mean diel patterns of CH₄ flux during the different growth periods of the rice plant (vegetative, reproductive, and ripening) in the dry seasons (DS) of 2013 (a,b,c) and 2014 (d,e,f). The solid line represents the mean of all days at a given time of day (in 30 min intervals) and the shaded area represents the standard deviation.</p
