Info

SRI LANKA, a small island at the southern tip of India, had a population of 18.6 million in 1999. The country has an area of 65,600 km 2 , which is divided into two climate zones, wet in the southwest and dry elsewhere. The land is mainly flat with a central mountain range. Arable land is 14% of the total. Agriculture accounts for 38% of the workforce and 21% of the GDP. Rice is the second largest crop after tea. General information • GNI per capita PPP$, 2000: 3,460 • Internal renewable water resources: 43.2 km 3 • Main food consumed: rice, wheat, nuts, sugar and honey, oil and fat • Rice consumption, 1999: 99.2 kg milled rice per person per year Production season Planting Harvesting Major (Maha) Oct-Nov Feb-Mar Minor (Yala) Apr-May Aug-Sep Production constraints Both the harvested area and yield have remained more or less unchanged during the last 10 years, indicating the need to create a more dynamic rice research and development program. The major constraints to sustainable rice production in Sri Lanka are • Small holdings, limited ownership of land, and high costs of inputs, especially labor • Lack of credit and inputs (fertilizer and seed) • Inadequacy of trained personnel for decentralization of agricultural extension • Inconsistent government policies on rice imports • Low soil fertility • Degradation of irrigation facilities 222 Rice almanac
