A Rice Field with Poor Drainage (RMME) is a cultivated rice field enclosed by embankments, relying on an irregular water supply, and facing potential water scarcity risks at the onset, during, or towards the conclusion of the cropping cycle. Specific rice varieties are particularly well-suited to this type of rice …

The role of small dams with weirs is to raise the water table, expand rice growing areas and extend the availability of water in lowland areas to complete the agricultural cycle of lowland areas (rice and vegetable growing).

A water reservoir for growing off-season increases the farmed area, yields and production. A second growing season thus becomes possible.

The role of masonry micro-dams is to raise the level of the water table so as to supply wells and create water reserves for off-season farming activities.
