Furthermore, Article 121 of the norms requires proponents to demonstrate, through these technical studies, that prevention and mitigation measures in relation to the forest resources, flora and fauna are undertaken during the implementation of the land-use change. These sectors are therefore also the main financial contributors to the CUSTF through the payment of in-lieu compensation fees. Activities are undertaken through compensation agreements between CONAFOR and landowners of deteriorated forested land who apply and meet the requirements of the CUSTF programme. This arrangement is between the developers requesting authorisation of land-use changes in forested areas and the government, which operates the compensation scheme.
