The latter is often due to failure to prove that the land proposed for compensation activity has been degraded or else failure to demonstrate the legal ownership or tenure of the land. Furthermore, the existing setup does not allow tracing a specific compensation project back to a particular land-use change, thus limiting the ability to assess the environmental effectiveness of the overall scheme. A clear shortfall of the scheme is that compensation projects have a duration of only up to three years, without mechanisms in place to ensure continuity and permanence of the measures implemented.
