Needs Identified to Improve Baseline Definition

To improve the baseline estimation, an analysis of the impact of recent LU policies should be carried out, particularly the policy changes in the 2000s of the animal husbandry and forestry sector. 

Deforestation Dynamics Monitoring

Are current deforestation rates known?
Yes[3]
Deforestation Rate Target
23,420 km²/yr[3]
Deforestation Rates
Sources:[4][5]

Mainly driven by conversion to pasture land and to a lesser extent by agricultural land. Also, due to a lack of forestry related economic activities.

Rates of deforestation are based on the available LU-maps, produced by INEGI, scale 1:250,000. These maps have a high uncertainty, particularly at the local scale, as the minimum resolution of the maps is 50 hectares (deforestation in Mexico is a small-scale activity).

A satellite-based standardized monitoring system needs to be set up in combination with ground-based monitoring plots that can estimate deforestation at a scale of 1-2 hectares. The imagery is available, but a permanent infrastructure and personnel is required. Historic trends can be improved, as imagery is readily available for this scale.

Forest Degradation Dynamics Monitoring

Are current degradation rates known?
Yes[6]
Forest Degradation Rates
Sources:[7]

Degradation is partly due to agricultural practices (shifting cultivation with periods of forest fallow, mixed with periods of agricultural production), due to impacts of hurricanes, and unsustainable forest management.

Rates of degradation are based on the available LU-maps, produced by INEGI, scale 1:250,000. These maps have a high uncertainty, particularly at the local scale, as the minimum resolution of the maps is 50 hectares (deforestation in Mexico is a small-scale activity).

The carbon stocks in woody vegetation are derived from the national forest inventory data. About 1000 permanent inventory plots were established in Campeche during 2004-2007. A separate data based on allometric equations, developed in Mexico, was generated from an extensive literature search. These equations were used to convert the inventory data to biomass. A 50% carbon content was used to convert dry biomass to carbon stock. The soil carbon densities are derived from the INEGI national database on soil profiles that were established since 1960. About 220 soil profiles correspond to Campeche.

Currently, the national forest inventory is re-measuring all the permanent plots. As of 2009 on ward, all carbon pools are measured or estimated. These data are in the process of analysis. With these data a first approximation of the relationships between the various carbon pools and the occurring disturbance regime can be estimated, although with a high degree of uncertainty at the level of the state of Campeche, due to the small number of plots available. A network of permanent plots needs to be established, especially taking into account the various disturbance regimes and the state of recovering of the forest from disturbance.
