The Government is also studying the exploitation of gold, platinum and sulpide. Agriculture, Fisheries and Industry Agriculture and fisheries still engage a substantial proportion of the population and are the mainstay of the rural economy. Though Oman lies in an arid region of the world, it has considerable agricultural potential due to its size and geography, which allow for local variations of climate. Heavy government investment has introduced modern farming methods and machinery along with new crops and livestock. Research and experimental stations maintain the progress.
Fisheries is recognised as a valuable natural resource.
This industry has been revitalised by the Government through the establishment of cold stores and the grant of subsidies for engines and boats. The government's efforts at diversification of the economy has resulted in the construction of major cement plants, an oil refinery, and a copper smelter as well as medium and light industry producing flour, textiles, electrical components, plastic material and food products. Initially Oman's industrial development was mainly geared to construction support. Originally, industry was directed towards import substitutes based on indigenous resources. More recently, industrial policy is being steered towards exports.
