Integrated agro-forestry projects are being implemented in barangays Magdungao, Tagubong, Gemumua-Agahon, Dalicanan, Sablogon, Nueva Union, and Aglalana. A social industrial forest management agreement of 294 hectares of land has also been inked by the City Environment Office with Brgy. Agtambo.

Banking and lending institutions, gasoline stations, pawnshops, telephone and cable services, drug stores, retail and general merchandising enterprises, rice and corn wholesalers and retailers, private shops and public markets are located in the Poblacion.
The strategic location of Passi City brought to its commercial centers buyers and sellers of goods from Roxas City, Jaro, Leganes, Iloilo City, Leon, Sta. Barbara, and San Enrique among others. The commercial activities regularly bring 200 transient merchants with their loads of fruits, vegetables, and other agricultural products to the city’s markets. Others sell their wares of textiles, shoes, electronic items, kitchen wares and appliances inside tents which are set up overnight and are dismantled as soon as market hours come to a close. The increase in commercial activities brought about an increased volume of waste during market days. As of the present, the city’s garbage truck collects waste from the markets once a day. The market administrators perceived this to be inadequate and suggested that the number of trips should be increased to 4 during market days and to 2 on the day after.
