Description of the SLM Approach
Short description of the Approach
The Land Development Department has promoted lowering of saline groundwater table in recharge areas since 2014. The approach used is through: (1) Public relations and information spreading; (2) Planning demonstration sites; (3) Selection of farmers interested in participating in the project; (4) Providing knowledge and advice to those farmers participating in the project; (5) The preparation of demonstration plots, with shallow wells, in farmers' land.
Detailed description of the Approach
Lowering shallow saline groundwater is one method of preventing the spread of salt in soils. This has been promoted under the Land Development Department (LDD) at Bua Yai district Nakhon Ratchasima province since 2014. The LDD has been drilling shallow wells to: (1) provide water for farming, (2) reduce the amount of saline groundwater, and (3) to create a positive economic impact.
The approach used is through: (1) Public relations and information spreading using soil doctors, volunteers, community leaders, and sub-district administrative organizations who clarify project details to community leaders, sub-district administrative organizations and farmers; (2) Planning demonstration sites; (3) Selection of farmers interested in participating in the project. These farmers must have agricultural land in the recharge area and within the project focus of the LDD; (4) Providing knowledge and advice to those farmers participating in the project; (5) The preparation of the demonstration plot, with a shallow well, in the farmer's land.
The demonstration plot implemented in the recharge area under Mr. Boonchu Supho is planted with rice, sugar cane and various kinds of vegetables throughout the year, for greater productivity. Importantly, even in droughts it is still possible to pump enough groundwater for the crops. Rice yield have increased up to 5-10%, surface salt patches have decreased significantly, and the surrounding environment has more vegetation and living things. The farmers outside the area and surrounding areas have come to learn in the demonstration plot and want to engage in the project. The area covered by demonstration plots has risen to about 1,000 rai (160 hectares).
