Rainfed agriculture can be protected by adopting farm ponds. The harvested runoff water in a farm pond creates salinization / water logging problems so, it has to be lined to control the seepage losses. The article presents a review on the type of lining materials viable and to explore for a cost effective sealant which can be adapted. In comparison to clay lining, bentonite, LDPE and HDPE, HDPE in combination with concrete increases the durability along with the 100% seepage control with benefit cost ratio for HDPE lining in combination with concrete showed highest value of 10.4:1. Bentonite, though costly has shown significant results by reducing the seepage losses by 72% to 96% respectively, depending on the thickness of application. In vertisols, lining did not show any significant variation. Whereas alfisols, luvisols of arid and semi-arid regions require lining materials with diversified crops and conservative irrigation practices.
