area in the city covers only 109.12 hectares. Sugar is the major commercial crop in the city. About 36% of the city's agricultural land is planted in sugarcane, yielding 1.16 million gross kilograms annually for the domestic and foreign markets. Bais is also home to two sugar mills or centrals: Central Azucarera de Bais and URSUMCO. Fish production is the city's second income earner, with about 428 hectares of the land area devoted to fishpond development and operation and fish culture. Bangus (milkfish) culture is the dominant activity. In 2000, the bangus yield in the city was at 722 tons. The government of Bais operates ecotourism activities in the city, highlighted by whale and dolphin watching and nature treks. Two annual Bais festivals have also become tourism events: the Hudyaka sa Bais Mardigras (which was changed to Sipong Festival and later on changed back to Hudyaka) and the Christmas Festival (which showcases the city's, perhaps the province's only, giant rotating Christmas tree and colorful decors) since 1950. A concern of the city is its liquid and solid waste management. At present, liquid wastes are emptied directly without treatment into the Bais basin. The current dump site for solid waste is due for closure, and site development for a new 12.5-hectare sanitary landfill is being finalized. Bais is reported to be the last stronghold of the Spanish language in the Philippines, since some of the Spaniards are in the first settlement area of Negros, (and southeast of Bais) Tanjay. Education Bais has separated its DepEd Division (Department of Education) from the provincial division. Most of its 35 barangays have their respective public elementary schools, and only a few have public secondary schools. In the city proper, elementary and secondary public schools, a college, and a state university are situated.
