SUMMARY : Senegal imports six times more rice than it produced. In order to reduce the cereal deficit, the Senegalese government has undertaken the restoration and valorisation of saline soils. The Ndoff Valley project was implemented by GREEN SENEGAL in collaboration with ISRA with GEF funding. This paper describes the results of four activities: 1) the building of the dam to store rain water and stop the influx of saline water from the river; 2) the training of a hundred and twenty women on seed production technique; 3) testing of the adaptability of three species; and 4) participation of hundreds of women in several communities in production of rice seed. Three types of landscapes were identified as suitable for rice production: (1) The uplands for early varieties (90 days) - Same Sakhame, Gafrith and Electer 1- (2) The intermediate slope lands for early varieties that are tolerant to temporary flooding : Momobal, Momorane, Electer 2 ; (3) The flooded lands for late varieties (120 days) : Bacoundabal, Bacoundayèkh, Sintango. The recorded difficulties include erratic rainfall, salt accumulation and constraints in dam management. The dam built enabled the desalinisation of up to one kilometre of saline lands. The higher yield show that agrobiodiversity is possible in salty soils.
