AGRICULTURE: Sustainable water solutions urged, Drip irrigation, waste water may be studied by Nanchanok Wongsamuth
Thailand should pursue a holistic approach toward water management, since the current system focusing on short-term solutions such as digging reservoirs has proved unsuccessful, says Natural Resources and Environment Minister Suwit Khunkitti.
"Currently we are only looking at an end solution to the problem by setting up small projects such as digging reservoirs. We have used billions of baht and we have never been successful, whereas the problem has grown bigger," said Mr Suwit.
He advised looking at the cause of the problem, as well as the whole picture, such as how to allocate the amount of water we have to various areas, as well as the demand in each area.
"Marketing strategies are also supported by choosing to plant crops that give high returns, as well as teaching farmers to study world market prices."It may be a one-time investment using half the amount of the budget used for the government's skytrain projects worth 1.3 trillion baht," he said.
Skytrains provide service to only a few people while costing billions of baht. By investing in the water system, the government will receive its income back in terms of increased value of products. We should think of it not as a solution because water itself is a solution to life. It is used for drinking, agriculture and industry.
The minister made the comments on the sidelines of a seminar on Israel's water solutions, held by the Federation of Thai Industries and the Embassy of Israel in Thailand.
Abraham Tenne, the head of the desalination division with the Israel Water Authority, stressed the importance of educating people in the effective use of water.
Water in Israel costs US$2-3 per cubic metre since the government stopped subsidising water 2-3 years ago.
"Prices went up by around 50%, while the amount of water consumption decreased. Then people started to think before using water, because it means that if you want to save money, save water," said Mr Tenne, adding that the government now developed more water projects using the money from citizens.
Mr Tenne said increasing the utilisation capacity of waste water for irrigation was a good start.
In Israel, 80% of treated waste water is used in irrigation, which it expects to increase to 100% within five years. The figure is only 15-17% in Spain, 5% in Australia, 5% in California and less than 1% in the United States.
Mr Tenne added that in Israel, 90% of the agricultural sector used drip irrigation, with almost 100% for gardens in the city.
Mr Suwit said the sugar company Mitr Phol's drip irrigation system had almost tripled the productivity of sugarcane from seven to 20 tonnes per rai. The costs of setting up a drip system can be recovered within three years. "That means you double income for farmers and less subsidy from tax."
The agricultural gross domestic product (GDP) of Thailand's northeastern region was 350 billion baht per year. Drip irrigation could help increase the figure to one trillion baht, he said.

water management - the process of managing the use of water when there is not enough, to make the best of the water resources that we do have (See Wikipedia)

drip irrigation - applying water slowly to the roots of plants with the goal of minimizing water and fertilizer usage (See Wikipedia)
waste water - sewage, used water from residential, business or industrial sources and has suffered a loss of quality as a result of use, household wastewater includes water from toilet drain outlets, and household waters drained from kitchens and bathrooms (See Wikipedia)
