The initiative provided tremendous benefits to various parties from an individual level to a global level, that is, farmers, RID, Thailand, and the ultimate world. At an individual level, farmers gained an understanding of water demand and supply in the areas, thus saving water for the next crop season. In 2009, farmers helped save water about 10 million m3 in the dry season. Farmers were able to do farming activities more than one time per year as well as to apply the crop diversification. Farmers’ income grew from US$3,900 per household/year to be US$5,233 per household/year (US$1 = 30 Thailand Baht). The yield of main crops in the area, i.e. rice and sugar cane, rose significantly. The rice yield of the first and second crops increased from 2,000 kg/acre to be 2,530 kg/acre and from 2,125 kg/acre to be 2,635 kg/acre, respectively. The sugar cane yield was 25 ton/acre and then turned to be 35.4 ton/acre after implementing the initiative. The plot preparation of tail-end farmers was reduced from six weeks to be four weeks because the initiative made the irrigated water flow faster through the end of a canal. The water conflicts between farmers and farmers and between farmers and public irrigation staff were dramatically decreased. Farmers were able to resume their relationships in the community. Farmers got great satisfaction in water service delivery supported by the initiative because they received water in a sufficient and timely manner. Finally, the initiative was a forum to devolve the water management decision-making to farmers, either through representatives or committee bodies, thus reinforcing the democratic society.
The initiative also assisted the RID in better maintaining the irrigation structures although its manpower was continuously downsized according to the 2003 Good Governance Reform Royal Decree. The manpower of the Kra Seaw Operation and Maintenance Office, for example, was 110 and 58 persons in 2001 and 2010, respectively. This helped save the salary about US$312,000 per year. The annual budget for canal and ditch maintenance was considerably saved US$53,333. The service satisfaction evaluated by farmers in the areas soared to 90% in the year 2008. The initiative helped the Kra Seaw Operation and Maintenance Office completely serve at least 6,740 farmers under the irrigation areas of 52,000 acres. The saving water allowed the Kra Seaw Operation and Maintenance Office to further supply water for domestic use of farmers outside of the irrigation areas of 28,000 acres during wet and dry seasons.
At the national level, the initiative led to ease water conflicts in Thai society. The increase of farmers’ income helped alleviate the standard of living of farmers. This helped maintain agricultural careers, which accounted for 34% of the country, conserved the irrigation areas, and enhanced the food and energy security of the nation. The agricultural export served as one of the main contribution of the GDP.
At the global level, the initiative promoted the food security of the world. The security was built on the food availability and food access through the Thai agricultural export.
