Planning a system of biosphere reserves

Mexico has a rich tradition of appropriate and locally-adapted use of its deverse biological resources. Unfortunately, the development of modern agriculture and growing demographic pressures are quickly causing the replacement of traditional land use by modern crops. This has meant an increasing loss of Mexico's biotic richness as ecosystems are transformed by deforestation and tillage. There is an urgent need to protect the country's natural heritage. national Parks and other conservation schemes have failed because they did not take into account the requirements of local populations. Biosphere reserves in Mexico, on the other hand contemplate the interests of local residents and include research for new rural development alternatives. Furthermore, they are conceived to protect representative parts of important biomes. Selection criteria for biosphere reserves can be grouped into four categories: political, biogeographical, ecological, and social. A system of biosphere reserves will help not only to conserve part of the biotic richness of Mexico, but will also help to generate new alternatives for the development of the country.
