IRRIGATION BY FLOOD RECESSION |

Definition characters description and diffusion
An elementary form of irrigation is the use of land left wet after the inundation of the flood.
General characters description and diffusion
The practice has developed with the expansion of the company’s growers along the courses of the great rivers, the Nile, the Indus, the Tigris, the Euphrates, and the Yellow River. It is present on a small scale in the early Neolithic societies and widespread in arid areas as a form of ‘Nomadic cultivation’. In this case, non-resident groups sow beds of wadis or hydromorphic soils remaining waterlogged after the withdrawal of the floods. No other activity is carried out until the time of collection after the return journey to the place of the nomadic group. On the banks of the Niger this practice is still used today by villages located in a strategic place with respect to the periodic occurrence of floods.
Advantages and sustainability
Flooded lands are used to cultivate crops due to their water retention from the flood waters, this way cutting out the need for irrigation.
