Thailand had issued a national strategic development master plan with issues related to water resources and water security in the entire water management. Water resources are an important factor of living and development of the country's socio-economy to be stable, prosperous and sustainable. Therefore, water management in both multidimensional and multi-sectoral systems is important and will supports socio-economic and environmental development. The direction of national development in accordance with the national strategic framework for 20 years that requires the country to level up security level in terms of water, energy and food. To response to the proposed goals, there is a subplan to increase water productivity of the entire water system for economical development use by evaluating use value and to create more value added from water use to meet international standard level. This study aims to evaluate the water productivity of Thailand in each basin and all sectors such as agricultural sector, service and industrial sectors by using the water use data from water account analysis and GDP data from NESDB during the past 10 years (1996-2015). The comparison of water productivity with other countries will also be conducted and in addition, the measures to improve water productivity in next 20 years will be explored to response to the National Strategic Master Plan goals. Water productivity is defined as output per unit of water depleted. The simplest way to compare water productivity across different enterprises is in monetary terms. World Bank presents water productivity as an indication of the efficiency by which each country uses its water resources. There are two data sets used for water productivity analyses, i.e., the first is water use data at end users and the second is Gross Domestic Product. The water use at end users are estimated by water account method based on the System of Environmental-Economic Accounting for Water (SEEA-Water) concept of United Nations. The water account shows the analyses of the water balance between the use and supply of each water resource in physical terms. The water supply and use linkage in the water account analyses separated into each phases, i.e., water sources, water managers, water service providers, water user at end user under water regulators of all kinds of water use activities such as household, industrial, agricultural, tourism, hydropower, and ecological conservation uses. The Gross Domestic Product (GDP), a well- known measuring method of the national economic growth is not actually a comprehensive approach to describe all aspects of national economic status, since GDP does not take into account the costs of the negative impacts to natural resources that result from the overexploitation of development projects, however, at present, integrating the environment with the economy of a country to measure its economic growth with GDP is acceptable worldwide. The study results will show the water use at each basin, use types at end users, water productivity in each sector from 1996-2015 compared with other countries, Besides the productivity improvement measures will be explored and proposed for the National Strategic Master Plan.

물발자국은 제품과 서비스를 생산하는데 전과정 혹은 전체 공급망에서 사용된 담수의 양을 나타낸다. 물발자국 평가는 인간의 활동과 관련된 물의 희소성 및 오염과 관련된 정보를 파악하는데 보다 많은 정보를 주기 때문에 물소비관점에서 지속가능한 물관리에 기여할 수 있을 것으로 기대된다. 물발자국 제도의 도입을 위해서 물발자국 데이터베이스/물계정이 필수적인데 국내에서 전 산업부분에 적용할 수 있는 DB가 전무하다. 따라서 이 연구의 목적은 산업연관분석법을 이용해 국내의 403개 산업분야에 대한 물발자국 인벤토리를 개발하는 것이다. 주요 연구결과로는 농업분야의 물사용량이 전체 직접수의 79%를 차지하며, 공업분야는 간접수의 사용량이 82%로 주를 이루는 것으로 분석되었다. 물사용량은 벼가 가장 많지만, 다음은 수산양식과 과일 생산으로 조사되었고, 가장 물사용강도($m^3$/원)가 높은 것은 비식용작물(103,263 $m^3$/백만원)로 분석되었고, 이와 같은 결과는 비식용작물(초지생산등)의 직접수는 많지만 경제적 가치가 매우 낮아 높은 물사용강도를 보여주고 있다. 다음은 육림, 철광석, 원목, 수산양식, 상수도, 잡곡 등의 순으로 물사용 강도가 높게 나타났다. 전체적 관점에서 총 물사용량중56%가 간접수가 차지하기 때문에 간접수를 고려한 산업분야의 수자원관리, 즉 공급망에서 전과정을 고려한 관리가 물사용 효율성을 높이는데 중요하다는 것을 알 수 있다. 전과정 개념과 산업연관분석법을 이용한 물사용강도 자료는 물발자국 도입시 제품단위 물발자국 산정의 기초 인벤토리로 이용될 수 있을 것으로 기대된다.

Korean distant water trawl fisheries were sector of most important distant water fisheries with tuna long liner fisheries during the development age in Korea. Nevertheless Korean distant water trawl fisheries have suffered from catches and Income problem. It was caused to the strengthen regulation of costal countries, the rapid liberalization trend of trade on the fishing products and the shortage of cheap manpower, etc. In this situation, Korean government is inclined to convert big adjacent trawl fisheries of distant water trawl fisheries for structure adjustment In domestic fisheries. that is analyzed to incorrect method because the efficiency of management indicator in adjacent trawl fisheries was bad than distant water trawl fisheries. Then this policy of Korean government needs to convert anything else. Also it was compared with one of Japan to the efficiency of management indicator of Korean distant trawl fisheries. The result of analysis, Korea was better than Japan in some factor, especially labor cost Then if Korean government will put weighted policy on this viewpoint, Korean distant water trawl can more grow.

Fisheries constitute an important sector in national economic development, and estimate to contribute about 3% of the total GDP and 5% of the GDP in agriculture. Fish production from aquaculture has been estimated at 950 tonnes for 2004. In 2003, Ghana produced only 51.7% of its requirements from its domestic sources and in 2004, achieved 68.1% of its fish requirement through domestic production and imports. It has been estimated that the production from ponds and culture-based fisheries is worth about US$ 1.5 million a year. The aquaculture sub sector comprises largely small-scale subsistence farmers who practice extensive aquaculture in earthen ponds in contrast to the intensive practices of commercial farmers. There is one cage facility which produces 200 tonnes or 21.1% of the total output. There are several laws to regulate and govern the sector and the government has set up institutions that are responsible for developing fisheries and aquaculture policy and directing and establishing research priorities. The Directorate of Fisheries (DoF) is the lead government agency for aquaculture development and the Water Research Institute of the Council for Scientific and Industrial Research (CSIR) is mandated to carry out aquaculture research. To promote fish farming, imports of farm fish are not allowed.

This study analyzed agricultural water distribution systems for the utilization of water demand-oriented water supply systems. Three major TM/TC(telemeter/telecontrol) districts of agricultural water management were selected for analyzing the characteristics of the water distribution systems. In addition, the characteristics of the water supply systems for general water supply zones based on irrigation facilities were also investigated, along with the case of special water management during the drought season. As a result, high annual and monthly variations were observed for the water supply facilities, including the reservoirs and pumping stations. In particular, these variations were more obvious during the drought season, depending on the type of facility. The operations of the pumping stations and weirs were more sensitive to the stream levels than the reservoirs, and the smaller reservoirs were influenced more than the larger reservoirs. Therefore, a water-demand-oriented water supply system should consider the existing general practices of water management in the agricultural sector, and focus on achieving a laborsaving system rather than water conservation in the case of reservoirs. Equal water distribution from the start to the end point of irrigation channels could be an effective solution for managing pumping stations.

In the past decade, many countries developed varies promising theories, methodologies and technologies for water resources management, such as Smart Water in Korea, eWater in Australia, Intelligent Water in Untied States, and Internet of Water in China. It is no exaggeration to say that Smart Water Management(SWM) will have a major role to play in addressing the global water challenges in the background of climate change, population growth and rapid urbanization. As a result, we can see major shifts taking place in the structure of the water industry, with a need for new approaches, skills, and water management policies. All these point towards a brighter future for the smart water sector and a new water paradigm, with applications and potential throughout the water cycle. However, each countries have their technology and industry standard system which may swift similar innovation and technology into different channels. In that sense, developing a common performance index and standard docking adapter for assessing Smart Water Management Initiatives(SWMI) is crucial for drawing a linkage of SWMI and SWMs to a way to implement advanced technology across Asia and Pacific. The performance index and standard docking adapter will facilitate quantitative and qualitative effects of utilized SWM techniques.

This study analyzes the perception of public value created by Korea Rural Community Corporation, a representative public corporation in the agricultural and rural sector. We categorize agricultural and rural public values as 'stable food supply,' 'conservation of national environment and nature,' 'formation and cultivation of water resources,' 'prevention of soil loss and flooding,' 'conservation of ecological system,' 'conservation of rural tradition and culture.' For the qualitative analysis, we apply content analysis. And, for the quantitative analysis, we use topic modeling and Latent Dirichlet Allocation (LDA) analysis which is used widely in the field of text-mining. Results show that internal perception for value suppliers are mainly created for 'stable food supply,' 'formation and cultivation of water resources,' and 'conservation of rural tradition and culture.' External perception for value demanders are created for all public values, but its evaluation and demand include various aspects including both positive and negative opinions.
