Socio-Economics, Institutional Support, and Intervention Programs Toward Sustainable Fisheries Management in Lake Mainit, Philippines
Socio-Economics, Institutional Support, and Intervention Programs Toward Sustainable Fisheries Management in Lake Mainit, Philippines Asuncion B. De Guzman, Alita E. Openiano, Marilou M. Ologuin and Jeanette J. Samson Mindanao State University at Naawan, 9023 Naawan, Misamis Oriental E-mail: [email protected] ABSTRACT Lake Mainit is an important natural resource shared by two provinces in northern Mindanao, Surigao del Norte and Agusan del Norte, notable for being the deepest and the fourth largest lake in the Philippines. This wetland ecosystem supports a thriving freshwater fishery and the livelihood of more than 4,000 fishers. At least 19 types of traditional and ingenious modifications of fishing gears are used. On the average Lake Mainit fishers earn an estimated monthly income of Php4,340 which falls below the poverty threshold for an average family in rural Philippines. Part of a comprehensive resource assessment project in Lake Mainit is a socio- economic profiling and appraisal of the numerous intervention programs in fisheries management and livelihood development introduced into the lakeshore communities in an attempt to improve the ecological and socio-economic situation around the lake. The results of this assessment will provide the scientific basis for formulating a comprehensive fisheries management plan for Lake Mainit that shall, in turn, be integrated into the Lake Mainit Development Alliance (LMDA) development agenda to help restore Lake Mainit fisheries to sustainable levels by addressing issues on declining water quality, regulation of fishing effort, and decreasing fisher income. Keywords: Lake Mainit, socio-economics, management issues, intervention programs, LMDA. INTRODUCTION Lake Mainit is an ecologically important resource within two provincial jurisdictions in the Caraga Region, namely, Agusan del Norte and Surigao del Norte, bordered by eight municipalities that comprise the Lake Mainit Watershed (Fig. -

Indigenous Religion, Institutions and Rituals of the Mamanwas of Caraga Region, Philippines
Asian Journal of Social Sciences, Arts and Humanities Vol. 1, No.1, 2013 INDIGENOUS RELIGION, INSTITUTIONS AND RITUALS OF THE MAMANWAS OF CARAGA REGION, PHILIPPINES Ramel D. Tomaquin College of Arts and Sciences Surigao del Sur State University Tandag City, Philippines Email: [email protected] ABSTRACT The Mamanwas, one of the IP communities of Caraga region. Said to be one of the original settlers of Caraga and considered the Negrito group of Mindanao. Only very few literatures and studies written about them. Despite of massive acculturation of other IP groups of the region such the Agusan-Surigao Manobos, the Mansaka/Mandaya, Banwaon, Higaanon and Talaandig. The Mamanwas still on the process of integration to Philippine body-politic. It is in this scenario they were able to retain indigenous religion, institutions and rituals. Thus the study was conducted. It covers on the following sites: Mt. Manganlo in Claver, Lake Mainit in Alegria both Surigao Del Norte, Hitaob in Tandag City, Lubcon and Burgus in Cortes and Sibahay in Lanuza of Surigao Del Sur respectively. The study used ethnographic method with strict adherence of the right of pre- informed consent in accordance with RA 8371 or Indigenous Peoples Right Act of 1997. It can be deduced from the paper that despite of socio- cultural changes of the IP’s of Caraga the Mamanwas were able to retain these practices but for how long? Moreover, socio-cultural change is slowly taking place in the Mamanwa social milieu. Preservation of these worldviews is wanting as a part of national heritage and for posterity. -

Sespeñe†・Marla Maniquiz-Redillas・김이형・추연욱 Department of Civil and Environmental Engineering, Kongju National University Cheonan City, Korea (Received : 22 June 2016, Revised: 02 August 2016, Accepted: 02 August 2016) Abstract The Philippines is a naturally water-rich archipelago capable of sustaining its ecological goods and providing services and needs of its people. Several waterbodies have been declared as natural wetlands in the country supporting the needs of community like water and food. In this study, 65 natural wetlands were considered including six sites that were identified as ‘Wetlands of International Importance’ such as Naujan Lake National Park, Agusan Marsh Wildlife Sanctuary, Olango Island Wildlife Sanctuary, Tubbataha Reefs Natural Park, Las Piñas-Parañaque Critical Habitat and Ecotourism Area and Puerto Princesa Subterranean River National Park. There are 22 wetland types presented in this research categorizing the Philippine wetlands. Philippine wetlands are now facing tremendous challenges such as land use conversion, abuse of resources, pollution coming from domestic, industrial and agricultural activities, and climate change. This paper provides an overview of Philippine wetlands in terms of their characteristics and components, impacts in the ecosystem, and the challenges they are dealing with. -

Baludo1*, Rey Donne S. Papa3, and Francis S. Magbanua2 1Institute of Environmental Science and Meteorology; 2Institute of Biology University of the Philippines Diliman, Quezon City 1101 Philippines 3Department of Biological Sciences, College of Science; and Research Center for the Natural and Applied Sciences and the Graduate School University of Santo Tomas, Manila 1015 Philippines Relatively limited information exists on Lake Wood’s limnology and ecology, an ancestral lake of the Subanens. Here, we provide a limnological characterization of the lake – exploring its physical, chemical, and biological features. The data on lake morphometry were gathered using an echosounder; lower depth water samples were collected using a Niskin water sampler for physicochemical analyses while surface water samples were collected at five sampling sites for phosphate (PO4) analysis; and zooplankton samples were collected at several depths through vertical towing in March–April 2019. Lake Wood, located at 320 m above sea level, has an extensive surface area covering 7.38 km2 with a maximum depth of 85 m. Lake water comes from rainfall, small rivers, and groundwater and empties into the Dumanquilas Bay via its only outlet – the Biswangan River. Land use of the lake is predominantly cultivated land. Moreover, based on the trophic state index (TSI), the lake’s current trophic status is eutrophic. During the study periods, thermocline and oxycline formed at 15 m below the surface of the lake. -

Floral Assessment in Lake Mainit Watershed, Caraga Region, Mindanao Philippines
Annals of Studies in Science and Humanities Volume 1 Number 2 (2015) : 12{28 http://journal.carsu.edu.ph/ Online ISSN 02408-3631 Floral Assessment in Lake Mainit Watershed, Caraga Region, Mindanao Philippines Meljan T. Demetillo1,∗, Richie P. Lador2 and Romell A. Seronay1 1Department of Biology, Caraga State University, Butuan City, Philippines 2Environmental Science Division, Caraga State University, Butuan City, Philippines Received: January 4, 2016 Accepted: June 15, 2016 ABSTRACT Lake Mainit is one of the Key Biodiversity Areas (KBA) in the Philippines with unique biodiversity resources that are at risk due to forest degradation and conversion of forested land to agriculture, shifting cultivation, and small scale mining activities. Thus, it is the main concern of this research to identify and assess the endemic and endangered flora of Lake Mainit and its watershed. The survey revealed a total of 202 species of which 14threatened species, 52 endemic species and 57 economically important species. The floral diversity in Mainit wa- tershed area is currently facing variety of threats which need to be countered if conservation of biodiversity can be seriously considered. Among the threatened species were Toona calan- tas, Dracontemelon dao, Dipterocarpus validus, Shorea negrosensis, Shorea contorta, Shorea polysperma, and the Agathis philippinensis. Noteworthy is the discovery of Raflessia mixta, a new species of plant found in a secondary growth forest of Mainit Surigao del Norte. This species is also considered site endemic, rare, and threatened. Thus, the result of this study would serve as basis for the formulation of policies for the protection and conservation of these species before these plants become extinct and the formulation of the Lake Mainit Watershed Management Plan. -
08 Incursion of Technology the Case of the Kaliwa Kanan Dam in Tanay, Rizal
• INCURSION OF TECHNOLOGY: THE CASE OF THE KALIWA·KANAN DAMIN TANAY, RIZAL ~CTF Research Staff "/ The worldwide reorganization of industrial production brought about by changed conditions for capital expansion 1 on the one hand, and the rise of authoritarian states in the Third World on the other - serve as the context against which the nature and extent of the impact of technology in the Philippines could be better understood. It is only in understanding such a context that "development" and ''underdevelopment'' could be seen as related facets of a single process rather than separate phenomena. In the mid-fifties, a new scientific and technological revolution swept • the industrialized countries bringing forth a new basis in the international division of labor. 2 The innovations that emerged out of sophisticated high technology brought with them new conditions for the expansion of capital. 3 Technological advancement in transport, communications, data trans mission and processing rendered production control less dependent on the geographic distance of industrial locations. It became "possible to have producion units in many different locations and yet control the whole network with a global management policy from the central headquarters.Y'' Hence in the mid-sixties, a reorganization of industrial production on an international scale ensued in the form of a massive relocation of world .' market-oriented industries for the industrialized capitalist countries to the Third World. This was the beginning of a re-devision of labor on the basis of which a small number of industrialized countries and a much greater number of under-developed countries (integrated into the world economy essentially as suppliers of raw materials and occasionally of cheap labor) stood ranged against each other:'s 'The new order of the international economy has made it possible for the Third World to become production sites of light, labor-intensive industries which utilize locally available cheap manpower to produce low-cost manufactured products of luxury food for export. -

Gastropod Fauna in Key Habitats Surrounding Lake Mainit, Philippines with Notes on Snail-Associated Diseases 1Joycelyn C
Gastropod fauna in key habitats surrounding Lake Mainit, Philippines with notes on snail-associated diseases 1Joycelyn C. Jumawan, 1Leonardo A. Estaño, 1Gemma H. Siega, 1Kariza A. Maghinay, 2Meriam M. Santillan, 1Jess H. Jumawan 1 Biology Department College of Arts and Sciences, Caraga State University; 2 College of Engineering and Information Technology, Caraga State University, Ampayon, Butuan City, Philippines. Corresponding author: J. C. Jumawan, [email protected] Abstract. Lake Mainit is the deepest lake in the Philippines. Nonetheless, cases of schistosomiasis were also reported in several communities surrounding the lake adding to concern to the tourism in the area. This gastropod survey was conducted in ten barangays surrounding Lake Mainit to provide an inventory of gastropods and their possible preference to habitats surrounding the lake. Collection of samples was done monthly from February to November 2014. A total of fifteen gastropod species from nine families were identified, with four species endemic to the country. Of these species, only one, Vivipara angularis, was utilized for food, and is collected abundantly in the lake. Other species were either considered agricultural pests (Ampullaria luzonica, Pomacea luzonica) while others were known vectors of zoonotic diseases such as Oncomelania hupensis quadrasi, Melanoides tuberculata, and Radix rubiginosa. Notably, known vectors of schistosomiasis were found in rice fields and creeks but not in the lakeshore study stations. This study is the first documentation of gastropods in five habitats surrounding Lake Mainit and will be helpful as baseline data for researches on snail-associated zoonotic diseases in this area. Key Words: schistosomiasis, zoonosis, diversity, Caraga region. Introduction. Lake Mainit is the fourth largest lake in the Philippines, and the deepest in the country (LMDA 2005). -
Large-Scale Active Fault Map of the Philippine Fault Based on Aerial Photograph Interpretation
活断層研究 39号 29〜37 2013 資料 Material 29 Active Fault Research, No. 39, P. 29~37, 2013 Large-scale active fault map of the Philippine fault based on aerial photograph interpretation Hiroyuki Tsutsumi*1 and Jeffrey S. Perez*2 Abstract The Philippine fault is a ~1250-km-long, left-lateral strike-slip fault extending NNW parallel to the Philippine archipelago. This fault has been very active in the past 200 years with several destructive earthquakes accompanied by surface rupture. However, there was no large-scale map of the Philippine fault, which is essential for mitigating seismic hazard from future earthquakes. We mapped the surface trace of the Philippine fault on 1:50000-scale topographic maps based mainly on interpretation of ~1:30000-scale aerial photographs. We then compiled these fault trace data on a Geographic Information System to produce the first digital active fault map of the Philippine fault. These 1:50000-scale active fault maps are available from the website of Philippine Institute of Volcanology and Seismology (PHIVOLCS). These maps reveal that there are notable along-strike variations in fault trace geometry and magnitudes of historical seismicity of the Philippine fault. The Philippine fault in central Luzon and Mindanao Islands are well segmented and produced large (M≥7) earthquakes. In contrast, the fault in Masbate and Leyte Islands are more continuous and produced only moderate earthquakes in the past 400 years. There are geomorphic and geodetic evidence of aseismic creeping on the Philippine fault in northern and central Leyte. These observations suggest that the Philippine fault may be comparable to the San Andreas fault in that both of the faults are composed of locked, transition and creeping segments as previously suggested.
