Avaliação do potencial de valorização econômica de Pinus pinea L. no distrito de Bragança: abordagem centrada na gestão multifuncional

Abstract

The forestry sector in Europe, in general, has some particularities directly influenced by biotic and abiotic factors. These particularities lead to negative consequences on the economic and social sustainability of rural areas. In several cases these issuescan be improved using a multifunctional management approach,in which timber production is complemented with other non-timber productions. In this way,the present work aimed to analyze the economic viability of a stone pine plantation installed for woodproductionand late converted to cone production, located in the Mirandela region (Bragança), in the heart of Terra Quente Transmontana, based on the multifunctional management of the forest. It also aimed to identify the potential and constraints for theForestry Sector in the Northern Region based on an analysis of secondary information from statistical data on forest rows, referring to the last 10 years (from 2008 to 2018).In this work we elaborated the production account of stone pine in Terra Quente.For the economic viabilityanalysis of the stone pine, the economic indicators were calculated: Net Present Value, Internal Rate of Returnand Paybackperiod. The analysis was made for three situations: (a) based on the actual production (of pinecones); (b) based on estimated expected production; and (c) based on actual production complemented with honey production and mushroom collection. A sensitivity analysis was also performed varying the market prices of pine,woodand nonfamily workhours. The results obtained show that the three situations presented economic viability. However, the scenario with the greatest economic attractiveness is the one thatincludes the activity of pineconesharvests, honey and mushrooms. This phenomenon shows that even with the production of pineconeslower thanexpected, the harvest of honey and mushrooms proved to be viable income alternatives for the producer. In the sensitivity analysis, the market price of the pineconeand the costof itsharvest were the factors that most influenced the viability andeconomicinterest inthe simulations.
