WAVES Technical Report Laguna de Bay Basin November 2016 Pilot Ecosystem Account for Laguna de Bay Basin Wealth Accounting and the Valuation of Ecosystem Services www.wavespartnership.org WAVES – Global Partnership for Wealth Accounting and the Valuation of Ecosystem Services Wealth Accounting and the Valuation of Ecosystem Services (WAVES) is a global partnership led by the World Bank that aims to promote sustainable development by mainstreaming natural capital in development planning and national economic accounting systems, based on the System of Environmental-Economic Accounting (SEEA). The WAVES global partnership (www.wavespartnership.org) brings together a broad coalition of governments, UN agencies, non-government organizations and academics for this purpose. WAVES core implementing countries include developing countries Botswana, Colombia, Costa Rica, Guatemala, Indonesia, Madagascar, the Philippines and Rwanda, all working to establish natural capital accounts. WAVES also partners with UN agencies—UNEP, UNDP, and the UN Statistical Commission—that are helping to implement natural capital accounting. WAVES is funded by a multi-donor trust fund and is overseen by a steering committee. WAVES donors include Denmark, the European Commission, France, Germany, Japan, The Netherlands, Norway, Switzerland, and the United Kingdom. www.wavespartnership.org Acknowledgments This report reflects the work of the Laguna de Bay Technical Working Group (TWG), led by Jocelyn G. Sta. Ana of the Laguna Lake Development Authority (LLDA), with the guidance of Secretary J. R. Nereus O. Acosta. The ecosystem accounts were developed by the TWG members from the LLDA, namely: Emiterio C. Hernandez, Alvin A. Faraon, Neil V. Varcas, and Erwin Kim P. Mercado (Land Accounts); Rowena J. Pagdingalan, Brando M. Angeles, Cruzadel T. de la Cruz, Dennis A. Tiongson, Donnie A. Limtian, Sarah Louise S. Yumul, Adelio Rico, and Ma. Carolane P. Gonzales (Water Accounts); Adelina C. Santos-Borja, Bileynnie P. Encarnacion, Ireneo G. Bongco, Rose S. Bonifacio , Beniaflor G. Ada and Marigold M. del Prado (Fishery Accounts). The LLDA Public Information Unit also extended assistance. The work on the Laguna de Bay ecosystem account was coordinated by former Assistant General Manager Dolora N. Nepomuceno, who retired in June 2014, and was supported by the Philippines WAVES Project Coordination Unit at LLDA. The work likewise received technical inputs and advice from the National Economic and Development Authority (NEDA) and the Philippine Statistics Authority (PSA). It also received support from the National Mapping and Resource Information Authority (NAMRIA) through remote sensing analysis and additional datasets. The development of the ecosystem account was supported by the World Bank-led Wealth Accounting and the Valuation of Ecosystem Services (WAVES) project in the Philippines, which provided technical and financial assistance. The Philippines WAVES Team would like to thank and acknowledge the representatives and officials of the various local government units, civil society groups, private sector, non-government organizations, and the academe who were involved in or supported the development of pilot ecosystem account for Laguna de Bay. The GECOMON project of the European Space Agency also supported the development of the ecosystem accounts, which involved technical assistance by two consultancy companies, GeoVille and Argans. It was also supported by Gem Castillo (national expert), Verna Duque (national expert), Arnan Araza (national expert), John Power (Australian Bureau of Statistics), and Lars Hein (Wageningen University). The following peer reviewers provided helpful technical guidance and advice: Yolanda Azarcon (Senior Operations Officer, World Bank), Kenneth Bagstad (Research Economist, US Geological Survey), Christophe Crepin (Practice Manager, World Bank), Vickram Cuttaree (Sustainable Development Program Leader, World Bank), Stig Johansson (WAVES Program Manager, World Bank), Frauke Jungbluth (Lead Agricultural Economist, World Bank), Glenn-Marie Lange (Chief Technical Advisor, World Bank), David Llorito (Communications Officer, World Bank), Carl Obst (Director, Institute for the Development of Environmental-Economic Accounting and Lead Author and Editor, SEEA Ecosystem Accounting Guidelines), Stefano Pagiola (Senior Environmental Economist, World Bank), Agata Pawlowska (Portfolio and Operations Manager, World Bank), Ana P. Santos (Communications Consultant, World Bank), Stefanie Sieber (Task Team Leader, World Bank), Michael Vardon (Adjunct Fellow, Australian National University), and Maya Villaluz (co-Task Team Leader, World Bank). iii Laguna de Bay Basin Technical Report 2016 Note on the Report This final report presents the collective findings of the Technical Working Group for Laguna de Bay ecosystem accounting, a pilot undertaking conducted between January 1, 2014 and December 10, 2015 in the lake region. The Laguna de Bay ecosystem account explores potential pathways to developing specific accounts based on a comprehensive framework called the System of Environmental-Economic Accounting-Experimental Ecosystem Accounting (SEEA-EEA), which shows the interactions between the economy and ecosystems, consistent with the System of National Accounts. Although experimental in nature, the account is replicable across time and geographical scales (e.g., national). It is also useful in policy making. Through this groundbreaking endeavor, substantial capacity has been built locally to produce ecosystem accounts and update them on a regular basis, thus helping ensure effective policy making and sustainable management of natural resources. Case Study Area The pilot ecosystem account covers the physical watershed of the Laguna Lake. The name commonly used for this area in the Philippines is the Laguna de Bay (LdB) basin, which is used throughout this report. ‘Laguna Lake’ refers to the lake itself. iv www.wavespartnership.org EXECUTIVE SUMMARY As the largest inland water body in the Philippines and the third largest in Southeast Asia, the Laguna de Bay has been confronted with growing pressures on its ecosystems. Over the past decades, population expansion, urbanization, industrialization, deforestation, and land conversion have led to degradation of the lake water and its watershed. These are some of the key challenges facing the Laguna Lake Development Authority (LLDA) and other relevant government agencies tasked to manage and protect the lake and its resources. The dire situation affecting the lake today assumes greater significance when one considers that this large freshwater body is a multiple-use natural resource. It supports the fisheries sector and provides livelihood for more than 24,000 fisherfolk including fishermen and people working in the fishing industry; supplies domestic water through water concessionaires; provides irrigation water for approximately 103,000 hectares (ha) of agricultural land; and supports hydropower production. The lake is also used for recreation and industrial cooling and serves as a waste sink for household wastes and industrial and solid, liquid, toxic, and hazardous wastes. The Philippines is taking steps to address these and other ecosystem trends in the Laguna de Bay basin and elsewhere in the country. A vital step in this direction is the national government’s revitalized efforts to mainstream natural capital accounting (NCA), an evidence-based tool that takes stock of the state of a country’s natural resources, into policy making. An integral part of NCA is ecosystem accounting, which links natural capital analysis with economic data, thereby clarifying the contributions of the ecosystem to economic activities. Ecosystem accounts are useful for monitoring trends in natural capital and enforcing resource management policies. Today, the Philippines is one of the core implementing countries of a World Bank-led global partnership called Wealth Accounting and the Valuation of Ecosystem Services (WAVES). This initiative aims to promote sustainable development by mainstreaming natural capital in development planning and national economic accounting systems. As part of the WAVES project, the Laguna de Bay basin was selected as one of two pilot test sites in the Philippines to develop ecosystem accounts (the other being Southern Palawan). The ecosystem account was developed using an adopted standardized system called the System of Environmental Economic Accounting (SEEA) – Experimental Ecosystem Accounting (EEA) framework, which ensures consistency with regularly produced economic statistics at the national and international level. The ecosystem account covers the Laguna de Bay watershed and the Laguna de Bay region, the administrative jurisdiction of the LLDA,1 and comprises the following specific accounts: • a land account containing land cover and changes • a water account providing information on water quantity aspects • an ecosystem condition account indicating various terrestrial and water quality indicators, changes in lake bathymetry, and sediment loading 1 Covering the whole provinces of Rizal and Laguna; the towns of Carmona, Silang, and General Mariano Alvarez, and Tagaytay City in Cavite; the towns of Tanauan, Sto. Tomas, and Malvar in Batangas; the town of Lucban in Quezon; Pateros town; and the cities of Muntinlupa, Taguig, Pasig, Marikina, Quezon, Caloocan, Pasay, and Manila in Metro Manila v Laguna de Bay Basin Technical Report 2016 • an ecosystem services supply and use account indicating the flow

Proceedings on the Second Multi-Sectoral Consultation and Workshop 1 INTRODUCTION Stakeholder participation shall be a vital foundation of the management and development of the Marikina River Basin, in consonance with the Philippine Integrated River Basin Management and Development Master Plan’s encouragement of stakeholders’ participation. The rationale behind this is to (a) make service providers more responsive and accountable to beneficiaries; (b) align the provision of services with users’ needs and ability to pay, thereby improving cost recovery and sustainability; and (c) tailor arrangements for water service management to local practices. Involving stakeholders in the management and development of MRB allows for the joint identification of needs, innovative ways to meet these needs and ensures sustainability, in the long run. Further, it creates ownership of the decisions regarding Marikina River among the stakeholders, that will eventually ensure stable benefits, access to information and opportunities for the local communities, primarily but other key stakeholders both horizontally and vertically. In particular, the objectives of stakeholder participation are: Improvement of decision-making as the focus is on the views, perspectives and needs of the involved parties; Encouragement of public input and feedback mechanisms as proof that

    DAIRY DELIGHTS If you happen to be in the vicinity of Rizal province, you will find a packet of farmers engaged in carabao raising. The place is in Jalajala, Rizal. To oldies, it bespeaks of the many foregone memories when it was still under the now defunct KKK Program of the Ministry of Human Settlements. To the vetereran technicians, they called it “Saudi Arayat’ in reference to Saudi Arabia, local form since it seems far flung if you get to have this as your assignment. It is near Manila but, if you are lucky to be assigned there, you’d feel like in some remote places. Lights are not so common despite its proximity to geothermal plants. The land area is vast, but come to think of it, it’s mostly rocks and the river beds are dried up. Circling the Laguna de Bay on the south side, it’s lacking in activity. Not so many people could be seen except for some barrio folks with some goats lagging behind them. The teenagers are playing basketful, but they are quite a handful. By 5 in the afternoon, it seemed the sky has turned to grey with amber streaks of the sun already folding with the clouds in cover. Nothing could be as boring if you’d look at it. However, if you traverse some more kilometers after Pillia Rizal, you will see the town of Jalajala. In it, is a peculiar barangay of Llano. Some people have cows, goats and carbaos. They happen to comprise the Llano Farmers Multi-Purpose Cooperative, Inc.

The methodology employed in the project combined the 2000 Family Income and Expenditure Survey (FIES), 2000 Labor Force Survey (LFS) and 2000 Census of Population and Housing (CPH) to estimate poverty incidence, poverty gap, and poverty severity for the provincial and municipal levels. We acknowledge with thanks the valuable assistance provided by the Project Consultants, Dr. Stephen Haslett and Dr. Geoffrey Jones of the Statistics Research and Consulting Centre, Massey University, New Zealand. Ms. Caridad Araujo, for the assistance in the preliminary preparations for the project; and Dr. Peter Lanjouw of the World Bank for the continued support. The Project Consultants prepared Chapters 1 to 8 of the report with Mr. Joseph M. Addawe, Rey Angelo Millendez, and Amando Patio, Jr. of the NSCB Poverty Team, assisting in the data preparation and modeling. Chapters 9 to 11 were prepared mainly by the NSCB Project Staff after conducting validation workshops in selected provinces of the country and the project’s national dissemination forum. It is hoped that the results of this project will help local communities and policy makers in the formulation of appropriate programs and improvements in the targeting schemes aimed at reducing poverty.

    Pattern of investment allocation to chemical inputs and technical efficiency: A stochastic frontier analysis of farm households in Laguna, Philippines Orlee Velarde and Valerien Pede International Rice Research Institute Laguna, Philippines 4030 Selected paper prepared for presentation at the 57th AARES Annual Conference, Sydney, New South Wales, 5th-8th February, 2013 Pattern of investment allocation to chemical inputs and technical efficiency: A stochastic frontier analysis of farm households in Laguna, Philippines † Orlee Velarde †and Valerien Pede International Rice Research Institute Abstract This study focuses on the pattern between investment in chemical inputs such as fertilizer, pesticides and herbicides and technical efficiency of farm households in Laguna, Philippines. Using a one‐stage maximum likelihood estimation procedure, the stochastic production frontier model was estimated simultaneously with the determinants of efficiency. Results show that farmers with a low technical efficiency score have a high investment share in chemical inputs. Farmers who invested more in chemical inputs relative to other variable inputs attained the same or even lower output and were less efficient than those farmers who invested less. The result shows that farmers who invested wisely in chemical inputs can encourage farmers to apply chemical inputs more optimally.
