“…; IATSS ). This paucity of studies is consistent with the established lacuna in Philippine lake literature, namely the scarcity of small lake studies despite their abundance in the country, noting the overwhelming majority of the studies focus on major lakes (Brillo ; see also Guerrero , ), and the dearth of development‐oriented studies (with the overwhelming majority being limnological and aquaculture studies; see Brillo ,c, ,b,c). This situation suggests the need for a formal study on Pandin Lake ecotourism development to supplement the lack of information on this small lake, as well as ameliorating the literature deficit to a small degree.…”

This study examines the development of Pandin Lake, a small lake in the Philippines, particularly the unconventional evolution of the ecotourism enterprise for the lake and the accompanying issues. The study concludes that Pandin Lake ecotourism development is mainly an endogenous initiative and that the intervention of the relevant administrative agencies is critical in addressing the contemporary issues. This study discusses the following issues: (i) the reasons for studying small lakes in the Philippines; (ii) Pandin Lake and its administration; (iii) the ecotourism enterprise evolution and issues regarding the lake; and (iv) the conclusions. It also addresses the extant gap in Philippine lake literature: specifically the scarcity of scholarly works on development‐oriented studies, noting the field is dominated by limnology and aquaculture studies, and on small lakes, noting the field concentrates heavily on studies of big lakes.

“…1). Lake Taal was formed by the explosion of Taal Volcano (Papa and Mamaril Sr., 2011), and the SMLs were formed by the explosion of Mount Cristobal (Brillo, 2016a). Two of the SMLs, Lakes Yambo and Pandin, are referred to as twin lakes due to their proximity to each other, and unlike Lakes Calibato and Taal, these twin lakes are not heavily used for aquaculture but are popular tourist destinations (Brillo, 2016b).…”

“…Lake Calibato, the deepest of the SMLs (Tab. 2), is used for fisheries and aquaculture, the main source of the local community's livelihood (Brillo, 2016a), while Lake Taal, the third largest lake in the Philippines, has multiple resource uses, including tourism, recreation, and aquaculture and fisheries essential to the local community. Due to their economic importance, these lakes have been at the center of lake ecosystem management programs to mitigate human disturbances (Mendoza et al, 2019a(Mendoza et al, , 2019b.…”

Identification of aquatic consumer trophic pathways in four volcanic tropical lakes using fatty acid biomarkers

et al. 2022

Food web studies rely heavily on the use of traditional gut content analysis or the fairly popular stable isotope analysis rather than fatty acid analysis (FAA) despite its straightforward process, and ability to identify and characterize more diverse trophic pathways. In this study, we employed fatty acid (FA) biomarkers as a preliminary attempt to trace and characterize trophic pathways in food webs of four tropical lakes of volcanic origin in Luzon Island, Philippines - three clustered maar lakes (Yambo, Pandin and Calibato) and a large caldera lake (Taal). These lakes have a long history of human disturbance but limited ecological data. Knowledge of basal food sources and existing trophic dynamics of organisms are generally non-existent. Particulate organic matter (POM), zooplankton, and fish species were collected in August 2019 from the study lakes as representative of three trophic guilds. Non-metric multidimensional scaling (NMDS) and principal component analysis (PCA) were conducted to analyse FA profiles and characterize trophic relationships between representative organisms. For the POM, within lakes comparison of taxon-specific FA profiles showed a significant difference between the surface and near bottom depths, with the former dominated by photoautorophs and the latter by chemotrophs, suggesting the ability of FAA to effectively delineate between micro-organisms. Between lakes comparison also showed significant difference between the caldera and maar lakes, with the latter containing higher composition of bacterial FA, reminiscent of the considerably smaller lakes’ response to the impact of unmitigated organic loadings from anthropogenic activities. Taken together with the primary consumers’ FA profiles, analysis confirmed the ability of FAA to discriminate between FA profile sources. PCA explained >70% of the variance in the FA compositions for three trophic guilds in the two deepest lakes, which delineated both zooplankton and fish species food selectivity in each lake, alluding to FAA’s capacity to characterize dietary reliance of various species in an environment with numerous food sources. Although certain limitations were encountered, such as the specificity of the sampling depths for POM, and the small sample size of the representative species of the third trophic level, this study demonstrated the effectiveness of FAA as a powerful ecological tool for disentangling intricate lake food webs comprising various food sources. Overall, this study provided baseline information on basal food sources and trophic pathways of representative organisms from four tropical lakes. Taken together, FAA studies have wide application in understanding food webs, including anthropogenically-threatened lake ecosystems.

“…The concentration of such studies, however, is on the abiotic and biotic features of large lakes throughout the country (Brillo ; see also Guerrero , ). To date, and despite their abundance in the country, few studies have dealt with small lakes, particularly on aspects of their governance (see International Lake Environment Committee (ILEC) ; Downing ; United Nations Development Programme‐Water Governance Facility (UNDP‐WGF) ; Brillo ,c, ,b,c). The reality is that biological and physical studies alone, without complementary governance studies, are simply inadequate to sustainably develop lakes and address their problems.…”

Local governance of Gunao Lake, Tikub Lake and Dagatan Lake: Small lakes of the Mount Banahaw–San Cristobal–Malepunyo Corridor, Philippines

Although many lakes in the Philippines are threatened, the effectiveness of their governance has not received sufficient attention to date. This predicament is most severe in regard to small lakes as their localized governance has least been given consideration over the years. Predicated on this observation, this study explores the local governance of three small lakes (Gunao Lake; Tikub Lake; Dagatan Lake) situated between the Mount Banahaw–San Cristobal and Mount Malepunyo area. Specifically, it analyses the role of local governments in managing and developing the small lakes. Using data from interviews, observations and the few existing documents on these lakes, this study contends that the main feature of governance regarding the three lakes is the Municipal Governments’ commitment and determination, which is consequential in their development over time. For Gunao Lake, the failure of the Municipal Government of Dolores to link the development of the lake with the tourism agenda in the Mount Banahaw area has resulted in its lack of tourism development. For Tikub Lake, the consistent push of the Municipal Government of Tiaong for its tourism agenda is key in the incremental improvement and preservation of the lake. For Dagatan Lake, the persistence of the Municipal Government of San Antonio in pursuing the restoration project and searching for a patron to finance the endeavour is crucial in the revival of the lake. Overall, this study highlights the distinct praxis of local governance regarding each of these small lakes, extends scholarship in regard to lake governance and offers a broad template for managing the many existing small lakes in the country.
