Resumen:
Gebhardt et al. (2014) presented the Monitoring Activity Data for the
Mexican REDD+ program (MAD-MEX), an automatic nation-wide land cover
monitoring system for the Mexican REDD+ MRV. Though MAD-MEX represents a
valuable first effort toward establishing a national reference emissions
level for the implementation of REDD+ in Mexico, in this paper, we argue
that this land cover system has important limitations that may prevent
it from becoming operational for REDD+ MRV. Specifically, we show that
(1) the accuracy assessment of MAD-MEX land cover maps is optimistically
biased; (2) the ability of MAD-MEX to monitor land cover change,
including deforestation and forest degradation; is poor and (3) the use
of an entirely automatic classification approach, such as that followed
by MAD-MEX, is highly problematic in the case of a large and
heterogeneous country like Mexico. We discuss these limitations and call
into question the ability of a land cover monitoring system, such as
MAD-MEX, both to elaborate a national reference emissions level and to
monitor future forest cover change, as part of a REDD+ MRV system. We
provide some insights with the aim of improving the development of
nation-wide land cover monitoring systems in Mexico and elsewhere.
