INTRODUCTION 1.0 Background/Rationale Lake Mainit is the fourth largest lake in the country. It has a surface area of 149.865 km² more or less and lakeshore measuring about 62.10 kms. The lake belongs to Surigao del Norte and Agusan del Norte. It falls within the jurisdiction of the municipalities of Mainit, Alegria, Kitcharao and Jabonga. The lake is reported to be the habitat of rare fish species: the puyo or climbing perch and gabot . The species are said to have become rare due to the introduction of new fish species. Around the lake are habitats of other rare threatened wildlife. This gives the lake and its surrounding area a high ecological value, prompting a proposal to declare the Lake Mainit Watershed as a protected area under the National Integrated Protected Area System (NIPAS). The lake is very scenic. Its water has remained generally clear and clean. There are various points around it that are potential for tourist attractions. The Caraga Tourism Master Plan identified the lake area as one of the region’s tourism zones primarily for adventure and ecotourism. Major projects have been put in place in the area and various proposed interventions, which, include the establishment of a mini hydropower plant and flood control project in Jabonga, construction of more access roads and tourism project, among others, will be implemented. All of these will provide development opportunities to the area; however, some may bring threats, which could exacerbate the problems that are now being felt in the area. The stakeholders recognized the need to undertake careful planning and coordination of all policies and actions to sustainably manage the development of the lake resource. This concern prompted the Provincial Governments of Surigao del Norte and Agusan del Norte to establish a mechanism that could provide policy guideline in the protection, conservation, utilization and management of the ecosystem. With the assistance and interventions of the Local Government Support Program, the Lake Mainit Development Alliance (LMDA) was established on March 9, 1999. The creation of the Lake Mainit Development Alliance (LMDA) caters to the sustainable development of the area. Its thrusts, as outlined in the Environmental Management Plan (EMP), provide policy interventions in the implementation of programs, projects and related activities in the lake area. This document attempts to integrate the environmental management plan, municipal local development plans which include Comprehensive Land Use Plan (CLUP), Executive Agenda (EA), among others, to come up with a local sustainable development plan for lake Mainit. This plan is called the Lake Mainit Development Agenda, which attempts to integrate social, economic, technological, human, political, cultural and spiritual dimensions in the EMP. It also provides mechanism for the active participation of stakeholders in the management of the lake resource. Executive Summary 1 2.0 Objectives The Lake Mainit Development Agenda serves as a blue print for sustainable development agenda, that adheres to cohesive framework to provide policy-reference in the implementation of programs and projects. Specifically, the LA 21 serves as the basis to: 1. Ensure pro-active participation of the government, private sector, civil society, business and other stakeholders in the sustainable management of the lake resources; 2. Compliment the implementation of various programs/projects of government and non- government organizations; and 3. Provide unified policy interventions in the implementation of programs and projects. Integration Process The Governance for Philippine Agenda 21: Subprogramme on Localization (GO PA 21) Project has been an instrument in advancing the localization of Philippine Agenda 21, the local blue print for sustainable development in the country. With the GO PA 21 intervention, the LMDA has broadened its understanding in terms of managing the limited resources in line with sustainable development concepts. The logical step to follow after the strengthening of mechanisms and processes that advance sustainable development is the actual integration of sustainable development (SD) concepts into local development plans. This move is necessary in order to operationalize the concepts, and at the same time produce a concrete output as a document that serves as policy reference, for implementation of development programs and projects. Several legal contexts also pose as legitimate basis for the need to upgrade the existing EMP into a local agenda 21. Foremost is MO 47, issued last 1999, which direct the formulation of local sustainable, integrated, area-based development (SIAD) plans, as a continuing commitment to localize Philippine Agenda 21. A workshop entitled “Integration of SIAD in the Environment Management Plan of LMDA” was conducted to respond to the need to enhance the LMDA-Environmental Management Plan according to SD parameters and ensure that sustainable management of the lake is affected. A total of 46 participants attended the 3-day activity. 29 were LMDA members, while17 were from civil society organizations and the private sector. After the integration workshop, LMDA conducted a three-day writeshop. The writeshop attempted to integrate the basic elements of SD in the existing LMDA EMP and come-up with a Lake Mainit Development Agenda. Specifically, the writeshop intended to: a. Integrate the proposed changes in the EMP, as reflected in the outputs of the workshop (reformulated component objectives, additional/revised sub- components, change of component titles, other recommendations as outlined in the workshop outputs) b. Determine the final list of programs/projects for each of the component (High- Impact projects as priorities) Executive Summary 2 c. Formulate complete project briefs for all the identified high impact projects per component. The output of the Writeshop is a draft LMDA Development Agenda, which will serve as a complete guide in the sustainable management of the lake. However, this document still has to be subjected to series of consultation, preferably at the municipal level, involving all the major stakeholders (LGU, CSOs, private sector). The Lake Mainit Development Agenda shall be presented to the relevant development planning bodies and the local legislative bodies (provincial and municipal levels), and the LCEs. These activities will solicit and secure the support of the Provincial and Municipal Development Councils to the Lake Mainit Development Agenda, through legislated policies, such as ordinances, resolutions, or budget allocation in support of the plan. Lake Mainit Watershed: The Planning Unit The watershed framework as the basis for delineating the planning area. Watershed refers to the area that is drained by a common river system. For this particular plan, The planning unit covered the bigger Lake Mainit watershed which extends from Sison, Mainit and Tubod in Surigao del Norte and down to Tubay in Agusan del Norte. It covers all rivers that flow into Lake Mainit, the whole length of Kalinawan River and all its tributaries (See Figure 2). Activities within the watershed can have impacts on the lake or Kalinawan River, which will ultimately affect the coastal area of Tubay. The ridges of mountains serve as the natural boundaries of the watershed. Since these boundaries do not coincide with the political boundaries, there are some municipalities, which are not totally within the Lake Mainit watershed. In fact, only 81 out of 99 barangays are found inside the watershed.

  • 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.

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.

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.

  • 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.

    FLOOD HAZARD MAPPING OF RIVER BASINS IN CARAGA REGION, MINDANAO, PHILIPPINES THROUGH THE CSU PHIL-LIDAR 1 PROJECT Meriam Makinano-Santillan and Jojene R. Santillan CSU Phil-LiDAR 1, Caraga Center for Geoinformatics, Caraga State University Ampayon, Butuan City 8600 Philippines Email: Email: [email protected] KEY WORDS: LiDAR, flood hazard mapping, Caraga Region, Mindanao, Philippines ABSTRACT: In this paper, we share our activities and recent accomplishments in utilizing high spatial resolution Light Detection and Ranging (LiDAR) datasets and other geospatial datasets and techniques for flood hazard mapping of river basins in Caraga Region, Mindanao, Philippines through the CSU Phil-LiDAR 1 project. CSU Phil-LiDAR 1 is one of several projects under the “Phil-LiDAR1: Hazard Mapping of the Philippines using LiDAR” program initiated and supported by the Department of Science and Technology (DOST). Projects under this program are being implemented nationwide by fifteen (15) higher education institutions (HEIs) for 3 years starting 2014. An extension of the University of the Philippines’ Disaster Risk Exposure Assessment for Mitigation (DREAM) program, Phil-LIDAR 1′s purpose is for HEIs to utilize LiDAR datasets to generate flood hazard maps of their assigned project areas which are distributed throughout the Philippines. CSU Phil-LiDAR 1 in particular aims to derive Digital Surface Models (DSMs) and Digital Terrain Models (DTMs) from preprocessed LiDAR data, and to utilize these elevation datasets, together with data gathered from field surveys (cross-sections, bathymetry and hydrology) as inputs in the development of flood models. The flood models are then used to generate flood hazard maps of the river basins and watersheds of Caraga Region.
