GIS mapping and pattern distribution of smallhold pig farms in selected Barangays in the Municipality of San Joaquin, Iloilo

Abstract

This study was to produce a digital map of smallhold pig farms in selected barangays of San Joaquin, Iloilo through Geographic Information System (GIS) with the general objective to locate smallhold pig farms in the Brgys. of Balabago, Bulho, Dacdacanan, and Qui-anan. It also aimed to determine the annual production of pig farmers, analyze the pattern distribution in terms of different stages of pig production (breeder, grower, and finisher), and create a thematic map showcasing the location and pattern distribution of smallhold pig farms in the Municipality. San Joaquin is the southernmost Municipality of Iloilo province and has a land area of 234.84 km² with 85 barangays and purposely conducted the study in Barangays Balabago, Bulho, Dacdacanan, and Qui-anan. Smallhold pig farming is a classification of small-scale farming tending 20 sows and below or a maximum of 41 grower-finisher swine in a pig farm. The location of smallhold pig farms in four selected barangays, annual production of 1,057 heads of swine, pattern distribution with Observed Mean Distance of 492 m, 697 m, 507 m and Expected Mean Distance of 472 m, 553 m, and 482 m for breeder, grower, and finisher pig production, respectively, are concluded as random. The results of the study recommends for additional data collection of smallhold pig farms in San Joaquin, as to the suitability of the area for smallhold pig farming. As to the ongoing outbreak of African Swine Fever (ASF), GIS mapping of pig farms can be used for disease security outbreaks within a 3 km radius, thus preventing the spread of the virus to other pig farms while also reducing the implications to the economy of the Municipality.
