Item Pag-amlig kang dunang manggad: An analysis of the protected area management practices in the Northwest Panay Peninsula Natural Park (NPPNP)Biadora, Edison N., Jr.; Elizada, Glenn Cymark E.; Laging, Stewart E.; Salgado, Cielo (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2023-07)There is growing evidence that despite the government's efforts to preserve and conserve the Philippines' forests through implementing the Protected Areas (PA) System, threats to natural resources continue to rise. There is also a continued decline in the number of endangered species. There is thus a disconnect between efforts in establishing PAs and the increasing biodiversity loss, prompting government implementers, scholars, and NGOs to rethink and reevaluate their efforts against these threats. Our study investigated the case of the Northwest Panay Peninsula Natural Park (NPPNP) to identify and analyze the preservation and conservation strategies implemented by institutional and non-institutional actors and assess their effectiveness in response to the emergence of human-induced threats. To achieve these objectives, the researchers utilized an adapted METT-4 questionnaire supplemented by key informant interviews (KIIs), focus group discussions (FGDs), and document analysis to analyze the overall effectiveness of PA management. Data from management institutions and other organizations was utilized to scrutinize the emergence of human- induced threats vis-a-vis conservation and preservation strategies. Our study revealed that preservation and conservation measures employed by institutional and non- institutional actors do not translate to a reduction of human-induced threats in NPPNP. The overall result further implies that the NPPNP is currently targeted for the exploitation of natural resources for commercialization purposes.Item Does a coral reef enhance the productivity of its surrounding waters?Peñafiel, Christen P. (University of the Philippines Visayas, 2019-06)Coral reefs have long been assumed and continually claimed to be origins of very high productivity, but how they attract organisms from and export nutrients to their neighboring waters remains largely unknown. Specifically, this study aimed at determining the space-time dynamics of nutrients and biomass redistribution around Hibotkan Rock Sanctuary (HRS), Banate, Iloilo, a sanctuary reef established by Municipal Fisheries Ordinance No. 12 covering an area of 25 ha. Twelve (12) sampling stations were established for space-time nutrient profiling, phytoplankton count, and supplementary measurements of water parameters, and four (4) stations for fish (biomass) visual survey. Results were analyzed using spatio-temporal plots and the Pearson correlation matrix (5% significant level). Nitrite was observed to be limiting, while nitrate was the most abundant in the waters of HRS. The predominant temporal variations of nutrients followed the flood tide (FT) and ebb tide (ET) cycles. In general, the tidal current direction appeared to control the redistribution of the nutrients (NO3-, NO2-, PO43-, and SiO44-). This study further revealed that stations of high nutrient concentration usually coincided with low levels of dissolved oxygen (DO). Species of fish observed were all indigenous and well-known inhabitants of the coral reefs. Furthermore, no other families of fishes (such as those of commercial value) were caught on record. Overall, there was no clear indication of import or export of living biomass in the HRS area. It can be inferred from the results that the fabled high productivity of coral reefs has no clear scientific basis; consequently, the Marine Protected Areas (MPAs) concept also appears to have no solid foundation.
