We study spin ice system on kagome, a two-dimensional lattice of corner-sharing triangles. We introduce lattice deformations, which imply phononic degrees of freedom in the adiabatic limit. We use analytical and MonteCarlo calculations to see how these new degrees of freedom affect the short and long range spin interactions. We also use Monte Carlo simulations to obtain the magnetization curves, explore the phases and the ground states of this system in the presence of magnetic field.
