Wear on the physical-chemical and microbiological quality of tropical forest soils
In previous publications, I have emphasized that the increasing deterioration of tropical forest soils, fundamentally the soils of the Amazon and Africa, is a topic generally omitted within the strategies of environmental conservation, executed in ecosystems that have been modified through anthropic influence, either by agricultural activities, livestock, mining, industrialization or construction of urbanisms.
In this sense, even though the progressive impoverishment of tropical forest soils has not generated immediate attention from environmental organizations to correct the nutritional and structural imbalance that threatens to erode the superficial part of the earth's crust that provides life, the consequences of not taking action to attack this problem are translated into the deterioration of the physicochemical and microbiological quality of soils, an aspect that is not encouraging for environmental health.
For Dr. Eduardo Rojas Briales, who was in charge of the Forestry Department of the United Nations Food and Agriculture Organization (FAO), the soils of the Amazon and Africa are older and poorer, so he warns that if they erode, they cannot be recovered, either because they have a greater loss of nutrients and, in any case, achieving this is much more difficult and costly.
However, in view of this threatening situation, the FAO suggests that it is necessary to diagnose what has happened after the constant forest fires, whether or not there has been a change of use in the Amazon, while in Africa it is more a question of land tenure and ownership, as well as the historical rights of peoples.

Therefore, it is urgent to promote agroforestry models that favor land tenure and avoid deforestation, in addition to considering compensation mechanisms that reduce the use of tropical soils for agricultural production, in other words, the actions proposed seek to create moderate deforestation rates.

Greetings @lupafilotaxia Unfortunately, erosion in this type of relief would cause irreversible damage to our planetary system, although contributions have been made in this regard, I think it has not been handled with the seriousness that such a problem deserves. Thank you for sharing and we continue reading.
Greetings @madridbg
That is precisely right, the problems of erosion resulting from forest fires and deforestation persist, because no serious measures are taken to counteract this unfortunate situation.
Hello friend, an interesting and important topic, I also agree that action should be taken to improve these spaces since they are fundamental to our lives, but unfortunately not everyone sees it that way, I think they put it in the background. They don't see the impact and the great consequences it can have.
Hi @franyeligonzalez
Your comment is very opportune and correct. Unfortunately, society has relegated everything related to the environment to a second level, and this is a counterproductive behavior, since we are attempting against our own species, violating the balances of the biosphere, a space that has guaranteed us life until today, and even so we do absolutely nothing.
Greetings friend @lupafilotaxia. An important topic to consider, and as you point out, it has not caused enough impact on public opinion. These are necessary:
Because agriculture represents the largest proportion of human land use.
Right, one point in favor is to start a mixed agriculture, under methods that are in balance with the cycles of nature. Thanks friend @emiliomoron for your kind visit.
Hello @lupafilotaxia.
What you explain very well in this publication gives the possibility to carry out agricultural activities that do not cause a negative environmental impact, especially those involving deforestation as that practice that affects our environment.
Greetings friend and thank you for sharing.
Deforestation must be accompanied by a program of afforestation by cycles (use of wood/food crops/forest crops), in the search to maintain ecosystems in balance, and the ecological restoration of soils. Thank you friend @carlos84 for your visit.
