Deforestation in Mexico - Dimensions

Based in Lund, HG, V. Torres, A. L. Turner Wood.2002. Mexico. Critical analysis of the available estimates deforestación.USAID. SEMARNAT. Indicates that there is enormous variation in estimates of deforestation in Mexico, ranging from 75,000 hectares a year to 1.98 million hectares per year. Takaki notes that "It is important to note that you can not tell that one or other estimate of the rate of deforestation is" right "or" wrong. "As were calculated with different definitions, methodologies and data sources
, only can say that an estimate of the rate of deforestation carried out for a particular purpose, can not be compared with one that responds to a different requirement. "

An explanation of the wide variation in the data deforestation, refers to the definitions. If, as mentioned, it could say that the phenomenon of deforestation include the permanent loss of any wildlife community, should be put in the accounts the wooded areas of forests and forest loss, but also add the areas of scrub, scrub, mangroves, and other wilderness areas have been transformed to other uses, or who have lost their attributes of "wild." If one takes into account all this, you can reach Victor Toledo estimate that in 1989 1.5 million hectares deforested annually.

However, if we reduce the estimate only wooded areas, we obtain figures more consistent. Following this approach and establishing parameters that seek to standardize methodologies and to generate comparable data across countries, FAO has published its rating of Forest Resources, which Mexico had 69.016 million hectares of woodland in 1990 and went on to have 65,540 in 2000 and 64,238 in 2005. This means that in the period 1990-2000 were lost in average annual 347.600 wooded acres between 2000 and 2005, 260.400 hectares per year. You can see the data published by FAO

For its part, INEGI Francisco Takaki, presents data showing that, according to the first digital map of Land Use and INEGI vegetation built in 1980, ie the number of letters I, Mexico had 51.5 million hectares of trees. By integrating the Series II cards with satellite data of 1993, had 37.5 million hectares of trees. When the Series III produced information cards 2002, had 34.5 million hectares. That is to say that in the past (1980-1993), lost an average of 1.076 million hectares per year and in recent years (1994-2002) the annual loss of forests and jungles fell to 336.500 hectares per year. These are the data Takaki, meeting in a single box:
