show a dry spell only in the middle of the decade. Only a sustained dry period upstream produces drought conditions in the lower Mantaro Basin. Summarizing the results for the Mantaro River Basin, Figure 6.9 provides the average monthly results for the historical data, for 2050–2059, and for 2090–2099, when the trend-line scenario is used as an input in the hydrological model. For the Mantaro River Basin, as indicated in the figure for the Pongor and Mejorada sites, overall water availability decreases. However, a shift in the distribution of runoff is projected, with reducFigure 6.9.
