Hardy biofuel crops like Jatropha replace edible feedstocks that use arable land. In Rajasthan, Jatropha displaces grazing and forage on both public and private land. As Jatropha plantations mature, the loss of grass becomes more pronounced. Unconsidered impacts negate the benefits that the biodiesel program aims to create. Local land‐use impacts need to be integrated into decision‐making.
