    Economic analysis and adaptation measures of small-scale aquaculture in Roxas City, Capiz
    Baes, Marla May A. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2015-06)
    This research was conducted to find out the contribution of the aquaculture industry to the city and to the small-scale farmers of Roxas City. It also determined the socio-economic impacts brought by the hydrometeorological events and identified the adaptation measures employed by the local government and the aquaculture operators. This study used cost and returns analysis, market based approaches and OLS regression to analyze the data gathered from the 187 small-scale milkfish, mussel, and oyster farmers in Roxas City. The findings showed that the aquaculture industry significantly contributed to revenue, employment, production and profit. However, the industry was affected by hydrometeorological events which brought about significant damage cost. Most of the aquaculture operators employed various adaptation strategies to cope with these hydrometeorological occurences. Some of them, however, did not find it necessary to adapt because either they do not have enough money to finance adaptation strategies or they perceive that the impacts are not that significant. This study recommends that the government should provide other alternative climate-resilient livelihoods to the small- scale operators. It should also employ sustainable adaptation measures aside from providing trainings and seminars about aquaculture operation such as by integrating climate change adaptation techniques to aquaculture farming.

    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.

    Cost analysis of coral gardening in Bato Bukay MPA, Guimbal, Iloilo
    Acob, Philina Riva L.; Rojas, Jan Katherine C. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2016-06)
    This study analyzes the costs of coral gardening in Bato Bukay MPA in Guimbal. Iloilo. Cognizant of the degradation of their coastal areas and fisheries, the community of Bgy Nalundan, where the marine protected area is located, sought to find solution through marine conservation and coral gardening. Being the habitat and breeding grounds of fishes, coral reefs are one of the most important natural resources that people must protect. Hence, several projects were implemented to propagate the establishment of Marine Protected Areas such as the deployment of artificial reefs and coral gardening activities. Costs of coral gardening in the site were estimated using key informant interviews with individuals who were involved with or who were knowledgeable on the establishment and maintenance of the project, and from secondary sources, thereby enabling the computation of the total costs. A survey of randomly selected participants that included Contingent Valuation Method was conducted in barangays Nalundan, Calampitao and Cabubugan, to determine the socio-economic profile and estimate the local community support through their willingness-to-pay and willingness to support in kind. Proportional sampling formula, adjusted to small population was used to determine the number of these participants across the barangays. The total cost for coral gardening on its first year was estimated as Php 336.684 combining all the fixed, variable and opportunity costs incurred. Out of the total costs, 40% amounted as fixed costs, while 33% were variable costs, and 27% constituted opportunity costs. More people were willing to pay in-kind by volunteering than to pay in monetary terms for the project’s fund for sustainability.

    Valuing the conservation of sea turtles in Brgy. Lawi, Jordan, Guimaras: An application of discrete choice experiment method
    Aborka, Rio Rina B.; Gange, Gay Margaret A. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2017-06)
    To increase the population and remove the endangered status of sea turtles in Brgy. Lawi, Jordan, Guimaras, an effective and sustainable conservation program is a must. Using discrete choice experiment valuation method, this study determined the residents’ preferred conservation scheme for sea turtles in Brgy Lawi and estimated the conservation value for these creatures. A total enumeration of 204 residents was employed in the study. Improvements in listing status and the establishment of conservation facilities were the identified attributes of conserving sea turtles in the area. Results show that the establishment of conservation facilities with souvenir shop attribute level was mostly preferred. Income and age significantly affect the choice of the residents for improvements in a conservation scheme. Also, results show that the residents have positive attitudes towards conserving sea turtles and are willing to pay for it. The inclusion of an eco-tourism scheme, such as the addition of a souvenir shop that would open opportunities and generate income while still promoting the protection and conservation of sea turtles in the area is thus recommended. For further studies, the research recommended to include more attributes that could capture a wider scope of characteristic from the resource or good being valued.

    Factors affecting women's participation in small-scale fisheries in Miagao, Iloilo
    Abordaje, Ira; Nocon, Kimberly (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2023-05)
    Small-scale fisheries is considered as a source of income that contributes to food security and livelihood sustainability, especially in coastal communities. However, women who fish are marginalized due to traditional gender roles. Their contributions to fisheries are frequently overlooked in economic analysis, fisheries management, and policy decisions. Women also uniquely experience multiple burdens due to gender roles and social expectations. This study analyzed the factors affecting women's decision to participate in small-scale fishing in Miagao, Iloilo. The study used surveys and the data were analyzed through binary logistic regression. Results showed that age, educational attainment, marital status, family income, and husband's income were significant in predicting women's participation. Furthermore, women are given secondary, easier tasks than men, participating in fisheries impacts women’s economic contribution and empowerment, and women in this industry still allot time for reproductive work despite spending most of their time accomplishing productive work in small-scale fisheries.

    Analysis of the consumption pattern of microcredit borrower and non-borrower households from three urban coastal barangays in Culasi, Antique
    Ammen, Neil D. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2011-03)
    This paper analyzed the consumption pattern of microcredit borrower households from the three urban coastal barangays in Culasi, Antique, and compared that with the non-borrowers. A total of 140 households were surveyed of which 46, 50, and 44 came from barangay Centro Norte, Centro Población, and Centro Sur, respectively. Out of the total households surveyed, 40% were ‘identified borrowers and the remaining 60% were non-borrowers. In addition, while only 33% were identified as fishers, the bigger percentage belonged to the non-fisher households. Consequently, these groups were further categorized into (1) fisher-borrower, (2) non-fisher-borrower, (3) fisher-non-borrower, and (4) non-fisher-non-borrower and a comparison of the differences in their consumption patterns was executed. Survey results showed that the top three household expenditures of the three urban coastal barangays were food, debt repayment, and education. This study also investigated the impact of per capita monthly expenditure and other household characteristics on the budget share of 20 commodities (food and nonfood) consumed by borrower and non-borrower households and found that income elasticities of the said commodities significantly vary among household categories. Results from the estimation and correlation on the quadratic model suggested that borrowers of microcredit programs are better off in terms of consumption than non-borrowers.

    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.
