Two-Sided Concerns of The Tribes In The Amazon Rainforest

AMAZON CREATES IT’S OWN RAIN

Have you ever imagined about an ecosystem which produces its own rain? Well, the Amazon forest is a special case, wherein the rainy season was welcomed two months before it hit Latin America. The Amazon is also home to a number of isolated tribes. This means that the tribe-folk have to adapt to environmental changes in the area.

Previously, the researchers were confused regarding the early arrival of monsoon in Amazon but recent discoveries state that Amazon forest prepares its own rainfall. Generally, the process of transpiration is a part of photosynthesis, wherein, the moisture is extracted from the roots of the plants, accumulates on the leaves, and then, finally evaporates into the atmosphere.

According to the World Economic Forum, researchers at the University of California believe that at Amazon, the above-mentioned process goes one step further. The amount of moisture released into the atmosphere with the help of transpiration allows the occurrence of rainfall. The moisture released by the trees alters the atmosphere, thus causing a shift in the patterns of the wind that pulls the moisture from the ocean.

In a report published in 2012, scientists have studied the connection between the (early) Amazon rainfall and its flora. They found out that the plants release tiny salt particles which help the atmosphere to prepare the rainfall. At Amazon, plants play an important role in creating and controlling the rainy season.

FIGHTING AGAINST MODERNIZATION

If not the challenging ecosystem, the tribesfolk are fighting against the rapid rate of modernization. The various development processes at the Amazon region such as the construction of dams, roads, etc. are causing an effect on the thousands of last refuges of the indigenous tribes who depend completely on the forest resources.

Antenor Vaz, who was formerly associated with the National Indian Foundation in Brasilia, combined a wide range of records to map which confirmed about the isolated groups in seven South American countries. He laid the map over the maps of oil and gas production areas, deforestation, and planned or under-construction hydroelectric dams. Though the maps reveal the isolated groups are settled within the protected areas, these development activities are slowly creeping within their protected lands.

He also reveals that his maps generally do not cover the roads, which can create a major threat as they tend to catalyze deforestation etc.Developments in the Amazon forest are moving closer towards the tribes living in the deeper forest and who do not have any contacts with the outside world. We can just hope that the authorities do not ignore the interest of the tribes and work out a way so as not to disturb the delicate ecosystem of the Amazon.

Vaz says, “This [rush of] development is the greatest risk factor for isolated indigenous peoples and those in recent contact.”

The Amazon is a magnificent expression of life on Earth. We must keep in mind that, in the rush for development, biodiversity and indigenous lives cannot be compromised.
