SENEGAL is a West African country facing the Atlantic. It surrounds The Gambia and is bordered by Mauritania, Mali, Guinea, and Guinea Bissau, with an area of 197,000 km 2 . The country has mainly low plains, with foothills in the east. Twelve percent of the land is arable; 60% of the workforce in the population of 9.2 million (1999) is engaged in agriculture, which makes up 19% of the GDP. General information • GNI per capita PPP$, 2000: 1,480 • Internal renewable water resources: 26.2 km 3 • Incoming water flow: 13 km 3 • Main food consumed: rice, millet and sorghum, oil and fat, wheat, sugar and honey • Rice consumption, 1999: 71.2 kg milled rice per person per year Production constraints There are several constraints to sustainable rice production in Senegal: • Heat-induced sterility at the end of the offseason in irrigated areas • Cold-induced sterility in December • Shortage of water in the dry season • Poor maintenance of irrigation facilities • Cheap, low-quality rice imports • Inadequate and irregular input supplies: seeds, fertilizer, and credit • Lack of small farm equipment, especially for postharvest operations • Competition for labor by other production activities • Lack of a well-implemented rice policy • Weak research and extension support • Acid sulfate soils in the south (Casamance) • Periodic drought, affecting rainfed lowlands and uplands Production season Planting Harvesting Main season Jun-Jul Oct-Dec Off-season Feb-Mar Jun-Jul 216 Rice almanac
