    Economic valuation of seagrasses in Nueva Valencia, Guimaras: A contingent valuation study
    Bundal, Kristine Shiela Mae B.; Taperla, Roald Ray B. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2015-06)
    This study assessed the willingness of the residents of Guimbal, Iloilo, to pay for the conservation of seagrasses in Nueva Valencia, Guimaras. The study was conducted to find solutions to the problem of growing seagrass decline in the area. The lack of necessary policies or programs and conservation financing, that would protect and improve the integrity of the resource are putting a lot of pressure not only on the associate resources, but also on the livelihood of the people who are dependent on the resource. The contingent valuation method (CVM) was used to elicit people’s willingness-to-pay to contribute to a conservation trust fund for the protection and improvement of the state of the estimated 20- hectare area of seagrasses in Barangay Tando. It has been under serious threats of rapid decline ever since the occurrence of the 2006 M/T Solar-1 oil spill, which also affected the area. The study found out that 89.32% of the respondents would be willing to pay to support the conservation of the seagrass ecosystem. The study also found out that the primary motivation behind the willingness-to-pay of the respondents was their concern for the benefit of future generations. In addition, based on the people’s WTP, an estimated amount of PHP 900,917.64 could be raised annually to fund or support the conservation of the seagrasses and its associate resources in Barangay Tando. Given this potential source of revenue, the residents preferred a payment collection scheme through additional taxes on property or utility bills like electricity bill. Furthermore, this study reveals pertinent socioeconomic and conservation financing implications that need to be considered in managing seagrass resources.

    Conservation values of selected Bacolod City High School students for coral reefs in Sagay Marine Reserve, Negros Occidental
    Bocario, Sydney B.; Togonon, Celina C. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2016-06)
    Most studies on economic valuation take household heads as respondents since they earn money for the family and usually make most of the decisions. Other sectors of the society, especially the students or members of the youth, are rarely involved in these kinds of studies. Contrary to popular practices, this study considered the youth, particularly high school students, as the respondents of the survey. Through stratified and systematic random sampling, 400 respondents were chosen from five public high schools. Data was gathered from 80 students per school through a group administered survey. A protocol for a group-administered survey was constructed in order to ensure that data is collected in an unbiased, organized and systematic way. The willingness-to-pay of students in public high schools in Bacolod City for the conservation of the coral reefs in Sagay Marine Reserve (SMR) amounted to Php 3,156,894.02, per month. The selected mode of payment was through student government collection. The top reasons for their decision to pay were because of existence values, altruistic motive, and bequest value. Some of them were not willing to pay because they lacked funds, they did not trust the government, and/or they believe that the residents in coastal areas were the main reason why the resource is depleting. The factors that affected the students’ willingness-to-pay were price bid, household size, monthly income and perceived importance. This study found that high school students can contribute resources either in money or in-kind, and in fact the monetary WTP was within their capacity and cash received. This study may be significant to the youth by amplifying their roles in the conservation of natural resources. The methods employed in this study may also benefit future researchers and policy implementers.

    Socio-economic analysis of municipal fishing in selected barangays of Banate, Iloilo
    Bayani, Marie Joy G. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1999-03)
    The main objectives of the study were to determine the social and economic characteristics of municipal fishermen, costs structure, profitability level, and problems encountered by municipal fishermen in Banate Iloilo. The study made used of cost and return analysis to determine the economic condition of the respondents. This study covered the municipal fishermen of selected barangays of Banate, Iloilo. The study was dependent on the data given by the respondents and not all data maybe reliable. The assumption that changes in effort and adjustment in fishing stocks were taken into consideration. The findings of the study showed that 93.75 % of the fisherman respondents were dependent on fishing for their livelihood. All the fishermen except the hook and line operators could not be considered as absolute poor as their income compared to the poverty threshold. The cost and return analysis of the study showed that fish corral operators incurred the lowest opportunity cost, which amounted to PHP 31.47, while crab pots registered the highest opportunity cost of PHP 48.39. Set gillnet incurred the highest variable cost of PHP 80.62 per trip. Crab pot incurred the highest fixed cost, which amounted to PHP 56 0 per trip. In profit, crab pot incurred the highest gross profit with PHP 380.58, and hook and line registered the lowest gross profit of PHP 1.30 per trip. As expected, the crab pot incurred the highest net profit of PHP 276. 19 per trip. Moreover, in all profitability indices, crab pot, push net, and set the gillnet posted positive receipts. Fish corral and hook and line incurred negative profitability indices. The variations in the results can be attributed to the difference in gears used by the respondents, average trip per week, average hour per trip, percentage of motorized and non-motorized boats, and the average volume of catch per trip. The most common problem faced by the respondents was the presence of illegal fishing in their area. In line with the goals to increase the productivity and welfare of the small-scale fishermen in Banate, the government should give support and assistance in order to upgrade the living conditions of the municipal fishermen.

    Costs and returns analysis of municipal hook and line fisheries in selected coastal barangays of Hamtic, Antique
    Baldevia, Joan R. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1998-03)
    This paper aims to determine the social and economic conditions of municipal hook and line fishermen; the cost structure of the hook and line fishing method; the profitability level of the municipal hook and line fishermen; the sharing system employed in the municipal hook and line fishery; and to identify the problems of the municipal hook and line fishermen. The study utilized the cost and return analysis. The limitation of this kind of analysis is the assumption that changes in effort and adjustment in fish stocks are taking place simultaneously. The percentage and average analysis failed to take full consideration of the time element of the study since it was based at a "one-shot" interview. The locale of the study are the selected coastal barangays of Hamtic, Antique namely Brgy. Caridad, Mapatag and Asluman. Any conclusions in this study is only applicable to the area concerned by this fishing gear and does not apply to other fishing grounds. Findings of the study showed that the average income of the municipal household was PhP 4168 which was below the average monthly income in Region VI which was PhP 5339.8. They can not be considered absolutely poor however because their average monthly income was still higher to the regional poverty threshold which was PhP 8197/year. Food was the biggest cost outlay of the municipal household which accounted for 68% of the total household expenses. In terms of cost structure, variable cost accounted for 84% of the total cost per trip. This showed that in every fishing trip, the fishermen needs to have enough money to cover its operating expenses. The small percentage of the total fixed cost relative to the total cost shows the level of mobility of the fishing unit to move to another gear type or even to another market of the fishing industry. Labor cost accounted for 48% to total cost per trip which showed how labor intensive is the hook and line fishing method. The opportunity cost, on the other hand, accounted for 13% of the total cost per trip. Almost all indices of profitability posted a negative values. This negative economic profit indicate a definite evidence of economic overfishing. It also indicate that the fishermen should seriously rethink their position in the fishing industry. The differences in findings of the study among the three sample barangays can be attributed to three important variables. First, is the average hour/trip and the average trip/per week. Since this is a per trip analysis, this had an implication on all variables. Secondly, is the number of motorized boats per barangay. Motorized boats have a higher depreciation cost, opportunity cost of owned capital and running cost. Third, would be the number of boats with crewmen/operators per barangay. This reflect the percentage of the respondents with a sharing system and this would entail a higher labor cost and consequently to total cost per barangay. The sharing system was flexible as evidenced by the different sharing arrangement between Brgy. Mapatag which had a 50-50 sharing arrangement compared to Brgy. Asluman and Caridad which was 60-40. The primary problem of the municipal fishermen was the presence of big fishing vessels like the baby purse seiner. Other problems mentioned were the illegal fishing operations like trawling which operate during the night, lack of capital for repair and maintenance and bad weather conditions. The improvement of the socioeconomic conditions of the fishermen should call for a general improvement of the environment in which they operate. The recommendations of the study asserts that the government should develop additional employment opportunities outside the fishery sector. Fishing effort should be controlled by regulation of entry in terms of number of boats or gears employed because of economic overfishing. Large scale fishing like the baby purse seiner should be regulated and trawling be effectively prohibited to increase the resource base of the small-scale fishery. A clear boundary line should then be put up to avoid encroachment of the big fishing vessels to the municipal waters.
