Description of the SLM Approach
Short description of the Approach
This approach is the 'way' or 'how' the cut-off drain has been implemented on steepland in northern Thailand.
Detailed description of the Approach
Aims / objectives: The cut-off drain is a kind of soil conservation measure which functions in the way that excess runoff will gather in these drains, which are constructed parallel with each other, and leave the cropped field without causing damage to it. This cut-off drain will be constructed only on steepland with large acreage. Fields smaller than 0.16 ha will not have it. The digging of the cut-off drain will be done before rainy season, using one hand hoe breadth and 20-30 cm deep. In the following year, loose earth material may be dug up and the drain may eventually be as large as 40 cm wide and 40 cm deep. This is an indigenous practice which farmers do it by themselves in their farm and they are not paid for their wages by any agency. In some cases poorer people may be hired by richer ones to dig cut-off drains. State agencies and extension workers have never promoted this T and A anywhere.
