Moisture Retention Dams
To maximise the use of Thailand’s annual monsoon rains, His Majesty designed a system of small “check-dams,” which regulate the flow of water. The creation of multiple small reservoirs gives farmers immediate benefits and also replenishes groundwater.
• Royal Projects
In 1969, the King introduced a comprehensive program to assist northern hill tribe people engaged in unsustainable farming practices. By training the hill tribe communities in the production of various handicrafts, these programs have raised their income and their prospects, and at the same time have benefited the environment.
• Pa Sak Jolasid Dam Project
To help the farmers of Thailand’s central plains to exploit fully the waters of the Pa Sak River, His Majesty initiated a development project that created a new reservoir for water conservation and controlled irrigation. The dam has also helped with flood prevention on the outskirts of Bangkok.
• New Theory on Managing Agricultural Land
Combining concepts of water management with local control, His Majesty developed a strategy that promotes individual household reservoirs over large communal ones, maximising versatility while minimising costs. Overall agricultural production is boosted without the need for public funds.
• Use of Vetiver to Prevent Soil Erosion
To help stop the effects of soil erosion, the King initiated a program to plant certain varieties of vetiver grass, known for its ability to reduce siltation and stabilise the soil. The systematic application of the program has proven effective in maximising productivity and conserving precious water.
• The Chaipattana Aerator
Concerned with the quality of water in the Kingdom, His Majesty developed a device that keeps the water oxygenated and healthy. Its simple design and low cost make it easy to build and maintain, thus facilitating wide application nationwide.
• The Rama VIII Bridge
Always conscious of the daily problems facing Thais, His Majesty suggested the construction of a new bridge across the Chao Phraya River to alleviate congestion in Phra Nakhon and Dusit districts. Named after his brother, King Ananda Mahidol, Rama VIII, the graceful bridge has become a city icon.
• Pak Phanang Project
To stem the deterioration of the naturally fertile Pak Phanang River basin due to unmanaged population growth, His Majesty initiated co-operation between government agencies to use more effective agricultural resources, maximise economic gain, and reduce harmful environmental practices.
• Renewable Energy
Long before the need for renewable biofuels was widely apparent, His Majesty was actively researching the resource potential of locally-made palm oil. The resulting biodiesel has become a standard additive in the nation’s fuel, and its local sourcing is an inspiration for ongoing research.
