Tropical Regions

Location of the tropical and subtropical regions.

The tropical and subtropical regions are between the Tropic of Cancer (to the north by Mexico to the height of the end of Baja California until the Center of Tamaulipas, Mexico) and the Tropic of Capricorn (To the south, it pass by Peru and Brazil).

Between those two Tropical the rays of the sun arrive in a perpendicular angle, or more direct than on the tempered zones near the poles. The energy deposited in these zones penetrates with greater intensity. Here they are the more efficient terrestrial ecosystems as far as the solar transformation of energy to biomass (total mass of the alive beings that subsist in balance in a specific site).

Characteristics of the tropical and subtropical regions.

In view of its geographic location:

• They are rainy, by the high degree of vapor transpiration of those regions that the rain formation causes. Pluvial precipitation annual average oscillates between 1200 to 3000 millimeters. They have of 1 to 3 months of relative stations of rains.

• They are warm, because its annual average temperature, oscillates between 20 to 30 degrees Celsius.

• By its discharge pluvial precipitation, their grounds are predominantly acid, superficial, rocky and poor. The leaching (filtration) it causes that the grounds of these regions are poor in greater nutrients and minors. The high aluminum content dissolved in the water, is toxic for the plants, and it does that the radicular system does not grow sufficiently, which makes susceptible to being demolished by winds.

By that circumstance, the handling of these regions in general and grounds in special, must be careful not to lose indefinitely its vegetation and its animal diversity; as well as the natural landscape and its cultural surroundings, indispensable for the fortification of the tourist, social and cultural resources of such regions.

Importance of the conservation and sustainable development of the tropical and subtropical regions

The environmental services of the tropical and subtropical forests are diverse and among others they are:

• Protection against the erosion forests in their natural state retain the organic and inorganic matter present in grounds and they avoid that rains drag them to others sites.

• Water and protection of hydrographic river basins. In the forests it is captured, it retained and it released slowly the water stowaway and avoids that this one runs taking valuable nutrients. It allows to have water for consumption, irrigation and generation of electricity. They protect this way, the important hydrographic river basins (Usumacinta, Amazon, among others).

• Generation of carbon oxygen and capture. The emission of monoxide (CO) and carbon dioxide (CO2), originating of factories, automobiles, airplanes and other human activities, they warm up the atmosphere and they cause changes in temperatures, hydrological cycles and alter the climate in general. The forests by means of photosynthesis process captures carbon dioxide of the atmosphere and as secondary product releases oxygen, essential for the life.

• Diversity vegetable and animal, food and medicines. In those regions they inhabit diversity of species animals and vegetables, not yet discovered that they can serve for feeding of humans and animals; as well as to be of utility in the field of the medicine. When conserving the biodiversity of the mentioned regions, it contributes decisively to the preservation of the same human species.

In conclusion, when protecting the tropical and subtropical regions, are being contributed to reduce the global heating of the planet; to conserve the biodiversity; to protect excellent hydrographic river basins; to contribute to diminish desert areas and floods; and to conserve the natural, social and cultural surroundings, necessary to fortify the tourist resources; among other direct and indirect benefits, tangible and intangible, contained in the same ones.
