    Willingness-to-pay for the conservation of mangrove site in Dumangas, Iloilo
    Agapito, Arianne I.; Guadalupe, Ronell D. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2011-03)
    This study was designed to determine the willingness-to-pay of the residents of Dumangas, Iloilo for the conservation of the existing mangrove sites in their area. Data were gathered through personal interviews using an interview schedule among 240 household representatives equally distributed in six barangays: three coastal, three noncoastal. Results of the study showed that most of the study participants were aware and knowledgeable about the existence of mangroves, its uses and benefits. The popular barangays identified to have mangrove sites included Sapao (31.33%) and Ermita (32.92%). Using dichotomous choice willingness-to-pay method with randomly assigned bid prices, results showed that most of the study participants both from coastal (89.17%) and non-coastal barangays (91.67%) were willing to pay for the conservation of mangroves. The main reason cited was that they want to participate in programs by the local government that aims to conserve the environment. When adjusted to level of certainty, there was slight difference in the number of study participants who were willing-to-pay; mean willingness-to-pay amounted to Php 86.47 without adjustment to level of certainty and Php 76.17 when adjusted to level of certainty. Knowledge index rating, civil status and bid price were the significant factors that affect the willingness-to- pay without adjustment to level of certainty at 5% level of significance. When adjusted to level of certainty, knowledge index rating (5%) and bid price (1%) were the significant factors. Annual surcharge in Community Tax is the preferred payment vehicle of the study participants for the conservation.

    Willingness-to-pay for the conservation of Mararison Island and its surrounding waters in Culasi, Antique
    Aguirre, Angelluz C.; Jauod, Ferly Mae P. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2016-06)
    The island of Mararison in the municipality of Culasi, Antique Province is rich in natural resources and its beautiful scenic view has been attracting tourists. Overtime, the number of tourists has increased, making the island and its surrounding waters vulnerable to degradation. Protection and conservation of the island and its surrounding waters will promote its sustainability. This study was conducted to determine the willingness-to-pay (WTP) of the local residents of the municipality of Culasi for the conservation of Mararison Island and its surrounding waters. The study also described the socio-demographic and economic characteristics, level of awareness, knowledge and attitude towards the conservation and the reasons for the willingness to pay of the residents for the conservation of the island and its surrounding waters. The Contingent Valuation Method was used to determine the study participants’ WTPs. Binary logit regression was conducted to identify the factors affecting the study participants’ WTP. A pilot-tested interview schedule was used to collect data from 300 randomly selected study participants in 10 barangays in the municipality of Culasi in January to April 2016. The results showed that 86 percent of the study participants were willing to pay (with adjustment to certainty) for the conservation program. Without adjustment to the level of certainty, the annual household income, the randomly assigned bid prices, and knowledge index were the variables that affect the willingness-to-pay of the study participants. With adjustment to the level of certainty, the age, educational attainment (elementary and high school), knowledge index and randomly assigned bid prices were the variables that affect the willingness-to-pay of the study participants. The annual mean WTP of the study participants with and without adjustment to the level of certainty were Pl66 and Pl40, respectively. This study can be used by the municipality of Culasi as basis in planning for the conservation program of the Mararison Island and its surrounding waters.

    Value chain analysis of sergestid shrimp (Acetes Spp.) in Oton and Tigbauan, Iloilo
    Andres, Junaelle Kyla B.; Iguban, Myra Marie B. (Division of Social Sciences, College of Arts and Science, University of the Philippines Visayas, 2014-04)
    The sergestid shrimp industry in the municipalities of Oton and Tigbauan has contributed to income and employment of the local shrimp catchers, traders, and processors. This study described and analyzed the value chain of sergestid shrimp in these municipalities. Specifically, the study described the market actors, their marketing practices, and the value chain; determined the revenues received, costs incurred, and gross margins received by the market actors; identified roles performed by the men and women in the sergestid shrimp value chain; and identified the problems facing the market actors. Data were collected from personal interviews of 14 shrimp catchers, 9 raw shrimp traders, 11 shrimp processors, and one shrimp product trader. The shrimp catchers caught an estimated 132,758 kilograms of shrimp in a year. Most were sold (129,182 kilograms, 97.31%), with only the three commission houses handling an estimated 128,702 kilograms (96.94%). The major outlets of the commission houses included raw shrimp retailers and different types of shrimp processors. The highest average selling price (P372.73/kg), gross margin (P168.65/kg), and net returns (P161.39/kg) was received by one shrimp product retailer. Generally, the shrimp catchers were price takers, with the commission people as quantity leaders and seemingly price leaders. The net added value of shrimp increases as it is transformed into new forms such as the shrimp paste, dried shrimp, and shrimp mill. The men performed more strenuous roles (such as catching, hauling, and loading shrimp) while the women performed more time-consuming roles (buying inputs in catching or processing and selling). Adding value to the raw shrimp through processing can increase returns. Creative ways to create demand for raw and processed shrimp should be introduced. New processing technology, new market outlets for processed shrimps, and better packaging can increase demand for processed shrimp. With more players in the market, price can be set by more players.

    Willingness-to-pay for the conservation of Bucari Pine Forest in Leon, Iloilo
    Anaquita, Argena Hera E.; Santos, Jose Maria D. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2016-06)
    The Bucari Pine Forest has provided the municipality of Leon in Iloilo Province with both economic and environmental benefits. However, due to development plans, the Bucari Pine Forest has become vulnerable to degradation. This study estimated the willingness-to-pay of the residents of Leon, Iloilo for the conservation of the Bucari Pine Forest using the Contingent Valuation Method. The study participants were 320 local residents from eight (4 upland, 4 lowland) barangays of Leon, Iloilo. The final data collection was conducted in January 2016 to March 2016. Seventy-five percent of the study participants were willing to pay for the conservation of Bucari Pine Forest. The calculated mean WTP of the study participants with adjustment to the level of certainty was P3 3 5.00 per year or P27.92 per month. The factor that significantly affected the willingness-to-pay of the study participants was the bid price. This means that the higher the bid price, the less likely the study participant was willing to pay for the conservation of the Bucari Pine Forest. The information in this study can be used by local policy makers in drafting conservation policies and provide awareness on the importance of the conservation of the Bucari Pine Forest.
