Monitoring forest degradation in Mexico based on the national forest and soil inventory (Infys)

| description | There are many definitions of forest degradation, however, most of them are not operational because they do not propose variables to measure it. Its measurement is complex. Evaluation involves comparing the status of the forest at a given time with a previous state (reference condition or baseline). The challenge to follow-up the degradation process begins with its definition and the identification of the baseline. The present paper proposes a General Index of Degradation (IGD, for its meaning in Spanish) to assess forest degradation that occurs in Mexico in the time period between measurements of the National Inventory of Forest and Soil (Infys). The IGD is composed of indicators that take as input the Infys database. At the same time, the study aims to build a base line that will allow monitoring forest degradation in future years. The results at the scale of federal entity indicate that the states of Puebla, Veracruz, Morelos and Colima show no evidence of degradation processes (IGD) during the period evaluated. On the contrary, Querétaro, Tamaulipas and Mexico City recorded certain process of degradation. The value of the IGD weighted at the national scale indicates that in general, for the five-year periods evaluated (e.g. 2004-2009, 2005-2010, etc.) the country’s ecosystems do not record any significant degradation, i.e., the value obtained from the IGD is equal to the baseline value. However, at the local scale it is possible to identify areas severely degraded or even deforested. |

Sin embargo, la mayoría no son operativas dado que no proponen variables para medirla. Su medición es compleja; evaluarla implica comparar el estatus del bosque en un momento dado con un estado previo (condición de referencia o línea base). El reto del seguimiento (monitoreo) de la degradación inicia con su definición y con la identificación de la línea base. En este trabajo se propone un índice general de degradación (IGD) para evaluar la degradación forestal que ocurre en México en el periodo que transcurre entre mediciones del Inventario Nacional Forestal y de Suelos (Infys). El IGD está compuesto de indicadores que toman como insumo la base de datos del Infys. Paralelamente, el estudio pretende construir una línea base que permita dar seguimiento a la degradación forestal en años futuros. Los resultados a escala de entidad federativa indican que los estados de Puebla, Veracruz, Morelos y Colima no muestran evidencia global de procesos de degradación en el periodo evaluado. Contrariamente, Querétaro, Tamaulipas y el D.F. (Ciudad de México) registran cierto proceso de degradación. El valor del IGD ponderado a escala nacional indica que, en general, para los periodos evaluados de cinco años (e.g. 2004-2009, 2005-2010, etc.) los ecosistemas del país no registran procesos considerables de degradación, es decir, el valor obtenido del IGD es igual al valor de referencia. Sin embargo, a escala local es posible identificar áreas severamente degradadas o incluso deforestadas.
