| description | The sustainable utilization of forest resources consists of using them to generate wealth, improving social indicators and avoiding environmental imbalance. The objective of the study was to determine the environmental sustainability of forest concessions in the Department of Huanuco, Peru, through a multicriteria analysis based on the use of indicators. Indicators were built including the diversity of edaphic macro-fauna evaluated down to 30 cm deep, as evidence of soil conservation and maintenance state. The indicators were standardized using a scale from 0 to 4.0, 4.0 being the highest value of sustainability; they were subsequently weighted by multiplying the scale by a coefficient, based on their importance with respect to sustainability. A forest concession is environmentally sustainable, if the Environmental Sustainability Index (ESI) is ≥ 2.0. The designed survey was applied to stakeholders and workers of forestal concessions. To know if the ESI in 60% of forest concessions exceeds the value 2.0, the Chi Square test was used; Pearson’s correlation was also performed between indicators, with 95% reliability. The Chi Square test confirms that forest concessions with manual forestal utilization (60% of the total) are environmentally sustainable (X2 = 0.056, p-value = 0.814). A strong statistically significant positive correlation was recorded (r = 0.970, p-value < 0.05) between "conservation and maintenance of soil resource" (CMSR) and "conservation of wild flora" (CWFl) indicators. Manual forest utilization maintains harmony with the natural environment, and even when mechanized forestal is utilized with a reduced impact, it generates damage to the ecosystem. |

El aprovechamiento sustentable de los recursos forestales consiste en utilizarlos para generar riqueza, mejorando indicadores sociales y evitando el desequilibrio ambiental. El objetivo del estudio fue determinar la sustentabilidad ambiental de las concesiones forestales en el departamento Huánuco, Perú, mediante el análisis multicriterio basado en el uso de indicadores. Se construyeron indicadores que incluyen la diversidad de macrofauna edáfica evaluada hasta 30 cm de profundidad, como evidencia del estado de conservación y mantenimiento del suelo. Los indicadores fueron estandarizados mediante escala de 0 a 4.0, siendo 4.0 el mayor valor de sustentabilidad; posteriormente, fueron ponderados multiplicando la escala por un coeficiente, según su importancia respecto a la sustentabilidad. Una concesión forestal es ambientalmente sustentable, si el índice de sustentabilidad ambiental (ISA) es ≥ 2.0. La encuesta elaborada se aplicó a titulares y trabajadores de las concesiones forestales. Para conocer si el ISA en 60% de concesiones forestales supera el valor 2.0, se empleó la prueba estadística no paramétrica chi cuadrada; también se realizó entre indicadores, la correlación de Pearson con un 95% de confiabilidad. La prueba chi cuadrada confirma que las concesiones forestales con aprovechamiento forestal manual (60% del total), son ambientalmente sustentables (X2 = 0.056, p-valor = 0.814). Se registró fuerte correlación positiva estadísticamente significativa (r = 0.970, p-valor < 0.05) entre los indicadores “conservación y mantenimiento del recurso suelo” y “conservación de flora silvestre”. El aprovechamiento forestal manual mantiene armonía con el entorno natural, y aunque el aprovechamiento forestal mecanizado sea de impacto reducido, genera daños al ecosistema.
