Community knowledge and utilization of mangroves in Panabo Mangrove Park, Panabo City, Davao del Norte, Philippines

Abstract. Alimbon JA, Manseguiao MRS. 2021. Community knowledge and utilization of mangroves in Panabo Mangrove Park, Panabo City, Davao del Norte, Philippines. Intl J Bonorowo Wetlands 11: 51-57. Awareness of community knowledge and utilization patterns of mangrove ecosystems and their services is integral to conservation and management. However, this aspect remains to be less explored, especially in the Philippines. Hence, this study assessed the community knowledge and utilization of mangroves in Panabo Mangrove Park, Panabo City, Davao del Norte Philippines, using a survey research design. Through a simple random sampling procedure, 154 residents living near the area were surveyed using a questionnaire. Data were analyzed using frequency and percentages. Results revealed that the majority were knowledgeable of the existence and the services of mangroves except for their medicinal uses. It was also found out that many respondents have less to no knowledge of the different species of mangroves. Further, most respondents reported that they used the mangrove ecosystem as a food source on varying frequencies but never utilized it for other purposes such as fuelwood, medicine, dyeing agent, construction materials, fishing poles, household furniture, and other items.

Its crucial to get information about lead (Pb) heavy metal pollution from mining and oil palm plantation on species density in mangrove ecosystem, to anticipate its impacts. This study aimed is to compare the types and densities of vegetation in mangrove ecosystems allegedly due to mining in Setarap village, Tanah Bumbu Regency and oil palm plantations in Kuala Tambangan Village, Tanah Laut Regency. We also analysis the condition of waters (TDS, pH and DO) and organic content in sediments to acquire data from the South Kalimantan mangrove ecosystems. The results showed there were four species of true mangroves (Avicennia alba, Acanthus ebracteatus, Nypa fruticans and Rhizophora apiculate) could live well in the environment affected by mining or oil palm plantations. The species density for trees was low (933 ind/ha) for mangroves affected by coal mines, while those affected by oil palm plantations had higher densities (1,067 ind/ha). pH value of waters in affected area by coal mining showed more acidic value (pH 5.76) especially at the back, while those by palm oil plantations are more acidic (pH 6) in the estuary. Organic matter content in sediments affected by coal mines was in the range of 0.61-6.59%, while those affected by oil palm plantations showed higher values (0.12-2.19%). Lead heavy metal content (Pb) in waters affected by coal mines was 0.031-0.056 mg/L, while the area affected by oil palm plantations was of higher value (0.110-0.128 mg/L). Lead (Pb) levels in sediments indicate higher values than waters, which reach 3.512-6.046 mg/Kg (affected by coal mines), and in areas affected by oil palm plantations reaching 6.658-6.66 mg/Kg. The general conclusion is that vegetation densities in areas affected by coal mines are lower than oil palm plantations. The level of lead (Pb) pollution in the sediments is higher than in the waters.

The study basically aims at uncovering the reading attitudes of the Bachelor of Business Administration (BBA) students of the Bangladeshi English medium private universities. It has been observed that the private university students, coming from Bengali-medium colleges, read very little in English and consequently they hardly grow up as better readers. The study has used both quantitative and qualitative methods. For collecting quantitative data, a structured questionnaire was administered among the sampling respondents, 120 BBA students from six private universities located in Dhaka city, selected using simple random sampling procedure. On the contrary, for gathering qualitative data, the researcher depended on a number of classroom observations, focus group discussions (FGDs) that took place among 20 different BBA students divided into two groups, and teacher interviews (10 teachers). It is revealed from the study that the students have mixed attitudes towards reading. In some cases, they have been found enthusiastic readers who read due to their passion for reading or for having pleasure out of reading. However, in many cases, they have affirmed that they become anxious and bored of extensive reading. Besides, they mainly read for passing the examinations or obtaining good grades. Finally, it has been unearthed that both teachers and reading materials play vital roles in developing learners reading attitudes.Journal of Business and Technology (Dhaka) Vol.11(1-2) 2016; 91-110

Background: The ability of pregnant women to deal with early response to high risks is still below the average, which is one of the causes of complications that can indicate the welfare of the mother and her fetus. Objectives: The aim of this study was to look at the determinants that influence early detection of high-risk pregnancies. Methods: This study used an analytic design with a cross sectional design. The sample size of 112 from a population of 155 was obtained by simple random sampling. The independent variables are individual factors, interpersonal influence, filial value and commitment, while the dependent variable is the family's ability to detect high risk of pregnancy for 3 months, namely August-October 2020 at PMB Ika Mardiyanti. This study uses a questionnaire. Data collection in the form of a questionnaire. Data analysis using SEM-PLS. Results: The results of the significance test concluded that all the path coefficients and the T statistical value of personal factors on interpersonal (0.453; 6.612), interpersonal on filial values (0.753; 7.267), filial value for commitment (0.851; 17.048), filial value for ability (0.667 ; 4,679), commitment to ability (0.358; 2.356) is significant. Because all have a T-statistic value that is more than the T-table 1.96. Conclusion: The determinant factors that contribute to the ability of families to detect high risk of pregnancy need to be considered so that families are independent and have efforts to maintain the health of pregnant women in their families. In further research, it is necessary to involve other factors to improve family capacity, especially in the ability of families to detect high-risk pregnancies early.

Abstract. Kristiningrum R, Lahjie AM, Masjaya, Yusuf S, Ruslim Y, Ma’ruf A. 2020. Fauna diversity, production potential and total economic value of mangrove ecosystems in Mentawir Village, East Kalimantan, Indonesia. Biodiversitas 21: 1940-1953. Mangroves play important role in life. The benefits of the mangrove ecosystem consist of ecological and socio-economic values. However, it is a challenge to discern how the mangrove ecosystem provides a comprehensive economic value. This research is aimed to analyze the Total Economic Value (TEV) of mangrove ecosystems in Mentawir Village, North Penajam Paser District, East Kalimantan Province. This aim will be achieved by conducting fauna inventory, analysis of mangrove wood production potential, social-economic interviews, and infrastructure cost analysis as the inputs to calculate four elements (i.e. Direct Use Value, Indirect Use Value, Option Value, and Existence Value) to sum up the TEV. The research used a mixed-method combining both qualitative and quantitative methods. Fauna inventory was conducted using boat survey method and interviews with local fishermen. Data on mangrove wood production was obtained using the systematic random sampling method by establishing two plots with an area of one hectare for each plot to calculate mean annual increment (MAI) and current annual increment (CAI). The economic value of the mangrove ecosystem was calculated using market price values, replacement costs, and the Contingent Valuation Method (CVM). The results of fauna inventory consisted of 3 species of mammals, 1 species of reptile, 16 species of birds, 25 types of fish, 8 species of crustaceans, and 7 species of mollusks. The economic valuation resulted in the contribution of direct use value with 39.56% in the form of wood (94,875,000,000 IDR) and fishery products (103,500,000,000 IDR); indirect use value with 53.47% in the form of breakwater (38,028,881,407 IDR), abrasion resistance (218,549,528,110 IDR), and carbon sequestration (11,580,313,067); option value with 6.92% in the form of biodiversity (34,690,085,038 IDR); and existence value with 0.05% (241,500,000 IDR). All these resulted in the total economic value (TEV) of the mangrove ecosystem in Mentawir Village of 501,465,307,621 IDR. Therefore, this value can be the basis for policymakers in managing natural resources so that the ecosystem is more protected and sustainable, and can continue to provide environmental services for the welfare of the community.

Abstract. Raganas AFM, Hadsall AS, Pampolina NM, Hotes S, Magcale-Macandog DB. 2020. Regeneration capacity and threats to mangrove areas on the southern coast of Oriental Mindoro, Philippines: Implications to mangrove ecosystem rehabilitation. Biodiversitas 21: 3625-3636. Regeneration capacity is important as it determines the fate of an ecosystem. This study assessed six mangrove areas in the southern coast of Oriental Mindoro, Philippines to evaluate their regeneration capacity status. Four mangrove ecotypes were delineated namely seaward, middle, landward and riverine zones at each mangrove ecosystem, where dominant mangrove species were identified and selected for regeneration capacity study. Three subplots measuring 1 x 1 m2 were laid within the five 10 x 10 m2 survey plots established per zone. The juveniles were counted and categorized according to their height classes, using linear regeneration sampling method; where: RCI (≤40 cm) considered seedlings; RCII (41-150 cm) as saplings; and RCIII (151-≤300 cm) as small trees. Potential threats both anthropogenic and natural were determined through key informant interviews. Seven dominant species were identified across ecotypes in all mangrove sites, namely Avicennia marina, Avicennia rumphiana, Ceriops decandra, Rhizophora apiculata, Rhizophora mucronata, Sonneratia alba, and Xylocarpus granatum. RCI (seedlings) is the most abundant across mangrove sites irrespective of the dominant species. Fishpond operation within the mangrove stand is considered a major threat to the juveniles and most mangrove ecosystems. Therefore, protection and constant monitoring of these mangrove ecosystems are necessary to ensure regeneration success in the future.
