Summary Feasibility Survey with the Private Sector for Utilizing Japanese Technologies in ODA Projects Feasibility Survey for an Application of Hydraulic Solidifying Cement "Haidegas" to Climate Change Countermeasures 1. Surveyed Country and its Situation The Republic of Kiribati (Hereinafter as Kiribati) is an island nation located in the Central Pacific Islands spreading across Micronesia and Polynesia. The country consists of 32 atolls and one raised coral island dispersed within its Exclusive Economic Zone over 3.5 million square kilometres, 800km from its north to south and 3,200km from its east to west, straddling the equator, and bordering the International Date Line to the east Kiribati consists of the three regions such as Gilbert Islands (17 islands), Phoenix Islands (7 atolls, 1 island) Line Islands (5 atolls, 3 islands) Total population is 103,000 people (2010 national census) and 91% of people live in the Gilbert Islands. The capital of Kiribati is South Tarawa, which has the parliament, cabinet and judiciary. Climate change has caused many disasters and intensified them, including sea level rise, cyclone and high tide, which also has effected a secondary disaster including serious water shortage. 2. Outline of the Proposed Product/Technology Feasibility and its Overseas Marketing Policy Seawall construction is urgently needed due to the serious damages caused by the disasters including cyclone and high tide. Seawalls in Kiribati are constructed by mixing the aggregates contained salt and sea water, as fresh water supply is limited, thus, kept for drinking purpose, and also to save the cost of the construction. This condition makes the seawalls in Kiribati less durable. The government of Kiribati recognises this problem and is seeking construction of more durable seawalls. Hashikanpura Ltd and Dobokuchishitu Ltd have decided to collaborate in marketing the HDG concrete to the overseas market after seeing that it has potential market in the atoll island nations. The atoll island nations have limited water resources, thus, it was considered there may be a demand for HDG concrete that can be used with seawater for construction and repair of seawalls and as building material. 3. Outcome of the Feasibility Survey for the Proposed Product/Technology Utilizing in ODA Projects Two main terms of references of this survey are: 1. To confirm the feasibility of HDG concrete production in Kiribati (adaptability, efficiency), and 2. To examine the possibility of smooth implementation of the HDG seawall construction plan (possibility survey). Three visits to Kiribati have been made for the field survey. The feasibility survey of the HDG concrete production in Kiribati was focused on the compatibility of the HDG concrete with the locally available aggregates and see if it can cater local needs. The mix ratio of HDG in Kiribati was investigated, and conducted the various types 81

of test using local (Kiribati) materials in Japan. Also the demand for construction/repair of seawalls was studied and how they were assessed by interviewing authorities concerned and conducting questionnaires survey to general public. The information of seawall construction methods in Kiribati were gathered from MPWU, related organisations, questionaries survey, and the seawall construction sites inspection. The information on the damages caused by king tides and possibility of using HDG as house construction material were gathered. Table-1 Outline of Field Survey Title Period 1 st Field Survey 22/Oct/2016 (Sat) - 2016/Nov/3 (Thu) 2 nd Field Survey 14/Jan/2017 (Sat) - 29/Jan/2017 (Sun) 3 rd Field Survey 15/Apr/2017 (Sat) - 27/Apr/2017 (Thu) Made by JICA Survey Mission Adaptability of HDG Seawalls in Kiribati are considered less durable due to its aggregates used contain sea water and salt, with assumption of 5-10 years durability. As the HDG concrete enables construction of the seawall with higher durability, it may be able to receive support in Kiribati. Effectiveness Coral sand samples were brought to Japan from Kiribati to conduct compressive strength test and sulphuric acid deterioration test using HDG and blast fume slug mixed samples. As a result, it was confirmed the sample has more than 30N/mm2 compressive strength at material age of 28 days, and deterioration performance is more than 5 times higher than conventional cement concrete (deterioration speed is 5 times slower than the conventional cement concrete). It was confirmed therefore that the HDG concrete mixed with local aggregates and seawater in Kiribati can be more durable against deterioration Economic Efficiency HDG cement per 1kg costs 3.40 times more than the cement available in Kiribati, and the HDG concrete costs 3 times more than the cement concrete in Kiribati in 1m 3. However, its durability is more than 5 times. This means longer useful life and lower life-cycle cost. Figure-3 indicates the age of the seawall (reconstruction of seawall after 15 years for conventional concrete vs More than 50 years with the HDG concrete). The life-cycle cost is expected to be more than 50% lesser than the conventional concrete in Kiribati. Practicality 82

There are no design specifications (ground plan/cross section) for construction of conventional sand bag seawalls. Newly introduced seawall, mass concrete type, has a standard drawing only to refer to for its construction. There are some examples that seawalls were built over a tree. This indicates they were constructed without checking the site topography, geological condition, surveying. Performance of the HDG concrete may be hindered by lack work experience in seawall construction and quality control knowledge among the on-site workers, even though the HDG concrete can build more durable seawall. For constructing seawall using the HDG concrete, enhancing the technical ability of MPWU and the on-site workers is needed. In order to solve the abovementioned possible hurdles, the following measurements are needed: The On-Job-Training (OJT) will be carried out to enhance experience in proper seawall construction. The OJT plan will be made in collaboration with those who concern. Technical workshop will be carried out to enhance skills and techniques of the on-site supervisor.

Poor mixing (honeycomb) Gaps at the joint of the concrete form caused slopes. Overusing of old concrete form caused gaps. The gaps filled with paper, when it melts, the gaps goes to cavity and weak point. Picture-2 Defect Sample 84

. 4. Proposal for Formulating ODA Project As discussed above, the HDG concrete has a great local adaptability and effectiveness. The project should include the seawall construction using the HDG concrete, making the seawall construction plan by OJT targeted on the engineers of MPWU providing the lectures for on-site workers. Table-2 The Project Plan (aim, action, expected result) Aim Proving superiority of the HDG concrete quantitatively by building the HDG concrete seawall as well as to and to prepare for future operation by strengthening institution of the counterpart through enhancing human resource for construction of quality seawalls. Expected Result Action Result 1: Superiority of the HDG concrete seawall is proven Result 2: Enhanced human resource for construction of quality infrastructure and institution of the counterpart is strengthened for the maintenance capability Result 3: Increased recognition of the HDG concrete made seawall and business operation plan is ready NB: PCDA Cycle=Plan, Do, Check, Act Cycle 1.1 Seawall construction (Divided into two sections) Identifying the problems and its solutions at the time of construction by PDCA Cycle, with an aim of improvement to construction and its quality. 1.2 Preparation of the seawall construction plan To construct high quality seawall at other locations 1.3 Verification of the superiority over the conventional concrete made seawalls quantitatively 2.1 Seawall construction by PDCA Cycle Dividing into 2 sections, identifying the problems and its solution of the seawall design and construction by engineers and on-site workers. 2.2 Holding a technical workshop for supervisors and construction companies. Planning of the workshop contents (Process/methods/important notes/handling of HDG) will be conducted when the above 1-1 starts. 2.3 Preparing the construction plan through OJT Providing the opportunity of learning a series of work including planning, simple field test, design policy, design, and costing. At the planning step, the cost and the expected degree of damages caused by the natural disaster will be assessed, instead of building the seawall at the designated site randomly. 2.4 Preparation of the manual and instruction book/workshop Providing the lecture for the companies who participated in the workshop held by MPWU. This lecture will be specialised in the technique of the seawall construction, and aiming at the technical improvement of the construction industry 3.1 Promotion to the private sector by opening the construction site during the construction work to the general public.

Detailed Plan of the Business Operation Table-3 Schedule for the Business Operation Period During Verification Survey 2 years after Verification Survey 3-4years after Verification Survey 4-5 years after Verification Survey Activities At the same time of the pilot survey, launching of the HDG marketing operation to the private seawall owners by collaborating with the government owned sea sand enterprise. Marketing to Kiribati Housing Corporation. Marketing to Kiribati s development partners Enhancing the sales outcome as privately owned seawall construction and house building materials in Kiribati. Commencing marketing to Marshall Islands and approach to the Pacific Islands Centre. Launching the sales operation in Marshall Islands Made by JICA Survey Mission 86

6. Expected Developmental Effects Marketing the HDG concrete for seawall construction can assist reduction of the life-cycle cost of seawalls, and facilitate more public and private seawall construction in Kiribati. This will allow resilience, thus, confidence, against natural disasters caused by climate change such as severe coastal erosion in Kiribati and other atoll nations. The effect of this resilience will assist the desire of most of the people in Kiribati; continue to live in Kiribati. It can also reduce the risks of the emigration to other country that may cause conflicts with the residents in the host countries. 87
