The study was carried out in Paundi Khola Sub-watershed of Lamjung District, with the objective of evaluating the effects of terrace riser slicing practice and it's alternatives. Terrace riser slicing height and signs of erosion were recorded through field observation and direct measurement. Key informantís survey, semi-structured walk and focus group discussions were also undertaken to acquire relevant information on positive and negative effects of slicing practice, perception of farmers on different issues and possible alternatives of terrace riser slicing.
Significant signs of erosion and its effects were not observed up to 1m sliced riser height. But beyond 1m the erosion signs appear significantly. The more the slicing height, high is the erosion and vice-versa. . Farmers perceive that benefit of keeping natural grasses on terrace riser is less than slicing them from the riser. Farmers believe that cutting the grass foliage periodically and partial slicing (low height of riser) may be good technique to keep grasses on terrace risers and edges without inducing soil loss and insect pest problem.
Key words: Effects, terrace risers, slicing, erosion, alternatives, improved varieties
