The present Occidental Mindoro is an agricultural area devoted to the production of food. It 's economic base is rice production (Oryza sativa culture), a Philippine staple crop. It is the leading activity and source of seasonal employment in the province, participated in by almost 80 per cent of the population, including children.
Wet land or lowland rice is a rainy season crop, being heavily dependent on water, and therefore produced from July (planting season) to October (harvest season). Tobacco, onions, garlic and vegetables are rather grown during the dry season (November to May)since they are not water-intensive crops, and require longer photoperiodicity.
Rice, corn, onions, garlic, salt, fishes(both wild water and cultured) are some of the relatively significant surpluses produced in the province in exportable quantities. Mangoes, cashew nuts, cooking bananas (saba) and some other fruits grown in upland orchards are among the other exports of Occidental Mindoro that have traditionally contributed to its income. Peanuts are also comfortably grown in some parts of the province, as well as cassava, sweet potatoes, ginger and other minor cultivars.
Forest resources include timber and minerals, among them gold, copper, silver, chrome, and non-metallic minerals such as lime for making cement, and greenstones for ornaments. Timber groups include many species of hardwoods, such as mahogany, and other types of trees in high demand for durability.
There are no large industries in the province. The government is the biggest employer, absorbing most of the off-farm labor force. The local electric cooperative, Occidental Mindoro Electric Cooperative (OMECO), is the biggest employer in the private sector, with nearly 150 regular employees. The rest of the population are engaged in private trades.
