Activity based costing of the nucleation techniques implemented in forest clearings due to oil exploration in the Central Amazon
The objective of this work is to present the costs of nucleation techniques in environment restoration from damaged areas due to oil exploration at the Geologist Pedro de Moura Operation Base – BOGPM, identified by Petrobras as LUC 15, JAZ 104 and JAZ 94. Three nucleation techniques were used: topsoil, artificial perches and dead wood/sticks. Nucleation consists in forming propagation nuclei in small strategic points of the area to be restored. The technique takes advantage of existing natural resources in the area, which reduces the cost of restoration. We registered the time of execution from each activity, the manpower and the input used. The data was analyzed by the method of Activity-Based Costing (ABC). For the three techniques, we found that cleaning of the damaged area was the activity that consumed more resources. For the topsoil technique, the activity of collection and transportation of the forest floor were also identified. The use of topsoil was the most costly technique, followed by the activities of dead woods/sticks and artificial perches respectively. We suggest the use of nucleation techniques to promote soil recovery to increase the number of propagule seedlings, to attract wildlife, and to act strategically in the landscapes, while minimizing erosion and costs.
Key words: restoration cost, Activity Based Costing (ABC), nucleation, oil exploration.
