Assessing socio - economic and eco - environmental effectiveness of forest production in Yen Lap, Phu Tho province

Abstract

There are six models of forest production plantation in Yen Lap and intensive small timber plantation models have high survival rate, the growth indicators and forest volume are high. There are no significant differences among the species, these indicators are significantly higher than with extensive forest plantation models. Effective evaluation results show that all plantation models of forest production are profitable, including large timber plantation model with the highest economic efficiency. However, large timber plantation model has generated the lowest number of labor forces per year in comparison with plantation model of Acacia mangium and Acacia hybrid. In aspect of ecological environment efficiency, Eucalyptus plantation models has higher soil erosion intensity (1.5mm year - 1 ha - 1) than the model of Acacia (0.78mm year - 1), intensive afforestation model has intensity erosion (0.81mm year - 1) compared with models extensive afforestation (0.71mm year - 1). Evaluating the synthetic effectiveness of models shows large timber planting has the highest Ect (0.82), this is the most efficient model while the eucalyptus plantation model has lowest Ect (0.60). Based on study results, the paper has proposed some solutions to improve the efficiency of forest production plantation development in Yen Lap.
