There are around 55 identified traditional and indigenous yams and tuber crop species in Sri Lanka and they grow in almost all parts of the country. The specialty of traditional yams is that they are easier to grow and can withstand unfavorable harsh climate conditions. As they can endure such soil and climate conditions, they require relatively less agricultural input, thereby leading to lesser agricultural expenses.
Designated as one of the global biodiversity hotspots of the world, Sri Lanka has some of the most biologically diverse ecosystems in the world because of its climate heterogeneity, coastal influence, and varied topography. Given that, it is home to a wealth of life forms including animals and plants necessary to maintain and preserve the ecological and genetic diversity.
