To use forest incentives for the favorable conservation of forest that are in private properties is a difficult process, that has encountered obstacles since the creation itself of the incentives and their conception through their application on part of fanners. In the actuality, exist tax and economic incentives that principally favor landowners and big companies and that in other cases propitiate deforestation of the natural zones. The certificate of forest incentive for conservation (CIF) is the incentive that is nearest to biodiversidad protection but in Colombia hasn’t been applied. The economic valuation of the benefits provided by the forest (positives externalities), may solve this conflict, if it compensates proprietors as well as the tropical countries. But the absence of volunteer, to pay people and the countries benefits is a link of a chain that it is missing. Since this panorama, the small proprietors of natural zones should organize and work to get tax and economic exemptions. This process should accompany research, technical assistance and financing on part of the national government.
