摘要：The last centuries of the Little Ice Age (1700-1900) led to a huge advance of flooded areas in the fluvial and endorheic basins of the Spanish peninsular center. This increase in the area of marshland appears to have had its origin in a combination of natural processes and anthropogenic activities. The former are related to considerable irregularities in annual rainfall as very dry years alternated with others of great humidity. The latterhave to do with human usage of soil and water. As a means of mitigating the general situation, countless works were undertaken to clear river beds and irrigation and mill ditches. These works, as well as the drying of wetlands, were carried out by wetland drainers known as paleros , an ancient profession which became remarkably important in some river basins of the region of La Mancha, such as the Záncara River, during the eighteenth and nineteenth centuries.
