EXECUTIVE SUMMARY Executive Summary PREFACE 0.1 Submitted herewith is the Final Report prepared at the end of the field surveys on ‘the Preparatory Survey on Malitubog-Maridagao Irrigation Project Phase II (MMIP II)’. A survey team organized by JICA headquarters commenced a series of field surveys for the Preparatory Survey from the beginning of May 2017, and this report presents major findings, flood simulation, project components, project cost, implementation arrangement, project evaluation, environmental and social consideration including indigenous peoples’ issues, and conclusion and recommendations. (It is noted that non-disclose information for 3-year is included hereunder as procurement by the Philippines government is scheduled.) 1. RATIONALE OF THE SURVEY 1.1 National Economic and Development Authority (NEDA) Board officially approved the Philippine Development Plan 2017-2022 on February 20, 2017. In this Plan, growth is expected to be more inclusive, where overall poverty ratio for the nation is targeted to decline from 21.6 % to 14 percent, and poverty incidence in rural areas to decrease from 30 % in 2015 to 20 % in 2022. Thus, the Plan puts priority on the poverty reduction in rural areas, e.g. central Mindanao area where the MMIP II site is located. 1.2 The Plan 2017-2022 is founded on three main pillars of: 1) regaining of people’s trust, 2) inequality-reducing through increasing opportunities for growth, and 3) increasing of potential growth through sustaining and accelerating economic growth. Under the second pillar, opportunities in agriculture sector are expected to expand. Further, under the three pillars lie cross-cutting strategies, i.e.: 1) attaining just and lasting peace, 2) ensuring security, public order and safety, 3) accelerating infrastructure development, and so on. In this regard, MMIP I, the foregoing project to MMIP II, is well known to have contributed to the peace and order in that area. 1.3 The National Irrigation Administration (NIA) has its six-year plan for the period from 2012 to 2017. According to this plan, the rate of irrigation development in central Mindanao area was as low as 41.7% compared to the national average of 55.6% in the year 2015. In order to address such under-development in irrigation and the challenge to poor maintenance for the existing irrigation facilities, among other challenges, the plan aims at accelerating the development and rehabilitation of irrigation facilities as well as a partial transfer of the O&M responsibilities of National Irrigation Systems (NISs) from NIA to Irrigators Associations (IAs). 1.4 The project site for the MMIP II has not been yet socio-economically developed. The agricultural production is low in spite of its potential being high, and thus improvement on irrigation facilities and agricultural productivity is an important development issue in the area. Based on these circumstances, MMIP II is expected to contribute to poverty reduction and long-lasting peace of this area. MMIP II could benefit the population of this area by bringing about an economic development through the irrigation development, hence, the MMIP II should be implemented/ completed as early as possible, and accordingly this Preparatory Survey is commenced. 1.5 In fact, this Survey was initiated by a request for Japanese ODA loan funding to the Lower Malitubog Service Area (LMSA), or to a part of the LMSA as MMIP II has been undergoing since year 2011. However, it is noted that flood simulation undertaken in this Survey revealed that dyke construction surrounding the LMSA for the purpose of protecting the area from flood coming from Pulangi river is not feasible technically and finically. With this outcome in which dyke should not be constructed, NIA has recognized that the current NEDA approved budget could be enough to complete the remaining parts of the MMIP II. JICA 1 NIA Executive Summary 1.6 NIA issued a letter to Department of Finance on May 22, 2018 stating that NIA would intend to withdraw its proposal for the funding of MMIP II through the Japan ODA financing as NIA believes that the remaining balance is too inconsequential for it to be funded by ODA loan. Following this NIA’s action, government officials of the Philippines raised during a Japan-Philippines Economic Cooperation Infrastructure Joint Meeting held on June 21, 2018 that the GOP withdraws the ODA loan request for the MMIP II. 1.7 With above withdrawal, this Survey now places priority more on its feasibility and sound development plan formulation of the LMSA. The outputs of the Survey are thus the recommendations of the project components, and investment scale of the MMIP II with feasibility evaluation, including measures against flooding. The Survey is therefore to investigate and analyze the different aspects of the project and consolidate the results in form of a project implementation plan taking into account the impact of Pulangi river flooding. 2. THE PROJECT AREA 2.1 The Project, Malitubog Maridagao Irrigation Project (MMIP) is composed of MMIP I and MMIP II, and the entire Project area covers 17,709 ha consisting of 7,173 ha from MMIP I and 10,536 ha from MMIP II. The Project site is spread over 5 municipalities of Carmen, Kabacan, Pikit, Datu Montawal and Pagalungan. The first 3 municipalities fall in Cotabato province while the latter 2 municipalities in Maguindanao province (ARMM). A total of 13,343 farmer households or 67,114 persons was estimated to be benefitted from the entire MMIP (5,518 households from MMIP I and 7,825 households from MMIP II). 2.2 The Project area of MMIP I starts at the diversion point established on the Maridagao river, through which water is withdrawn into the Maridagao Service Area (MSA), and then after crossing the river with a siphon, it irrigates the Upper Malitubog Service Area (UMSA) upstream site. The irrigation water further reaches to the MMIP II area, namely, UMSA downstream site, the Pagalungan Extension Service Area (PESA) and the Lower Malitubog Service Area (LMSA). Thus, the MMIP area extends over from north to south, approximately 27 km, and form west to east about 30 km. The diversion point has the highest elevation of 35 m, while the most downstream point has the lowest elevation, almost 0 m. 2.3 The implementation of MMIP I was commenced in April 1993 and completed in 2011, thus it took more than 17 years to be completed due to unstable peace and order in and around the Project site. The total project cost for MMIP I amounted to 3,184.34 million Php equivalent to JPY 8.43 billion, and out of which, JPY 4.541 billion was from the Japanese ODA Loan. In the same year 2011, MMIP II was started, and as of July 2018, leaving the area for which ODA Loan was originally requested, the MMIP II area has been either completed, under construction, or to be worked by already awarded contractors. For the MMIP II, the NEDA-ICC approved project cost is 5,444.84 million Php. 2.4 The Project area has a tropical wet climate being constantly moist, represented with year-round rainfall. There is not much temperature fluctuation throughout year ranging from 20 to 35 Celsius degree, with a bit of increase in March – May. The monthly basis rainfall indicates no clear demarcation between seasons; however, it is generally said that the rainy season is from May to October while the dry season is from November to April of the following year. The annual rainfall in the Project site marks only 902 mm, of which about 40% falls during the dry season, while the annual rainfall at the most upstream edge of the catchment area marks as much as 6,477 mm. 2.5 The population growth ratio in the Project area is higher than that of the national average. In 2015, the population of Cotabato province marked 1,373,962 and its land area covered 9,317 km2, NIA 2 JICA Executive Summary giving 148 persons per km2 population density. The average household size was 4.29. On the other hand, the population of Maguindanao province was 1,172,381 with the land area of 9,968 km2, showing the population density of 118 persons per km2. The average household size was 6.03. The Census of Population and Housing 2010 estimated about 1.7% and 1.8 % population growths for Cotabato province, Region XII, while approximately 2.2% and 2.4% for Maguindanao province and ARMM.
