Which is the most important reason that the agricultural practice of shifting cultivation occurs primarily in tropical rainforest regions?

Itinerant agriculture advantages and disadvantages

Itinerant, migratory or nomadic agriculture, also known as slash-and-burn agriculture[1] (although some differences can be established between the two), is subsistence agriculture practiced in vast regions of dense vegetation (jungle and tropical forests). Farmers open clearings in the vegetation, burn the trees, so that the ashes bring fertility to the soil.

After the soils are exhausted, farmers must go to another plot, which after being exhausted, they will move to another plot, and in the end, they will start again from the first plot they burned because the soils are replenished after a while.

Where is slash and burn agriculture practiced?

This agricultural practice, known as slash-and-burn agriculture, is common in the lowland areas of Ecuador, in eastern Peru and Bolivia, in the Amazon, in lower Colombia, in parts of Central America, in the Caribbean islands and in Madagascar.

What is slash-and-burn agriculture?

Maya slash system

Deforestation or logging is a process generally caused by human action, in which the forest area is destroyed.[1][2] It is directly caused by human action on nature, mainly due to logging or burning by the timber industry, as well as to obtain land for agriculture, mining and livestock.

Among the factors that lead to large-scale deforestation are: medieval neglect and ignorance of the intrinsic value, lack of attributed value, irresponsible management of forestation and deficient environmental laws.

Not all deforestation is the result of intentionality. Some is caused by human and natural factors such as forest fires and intensive grazing, which can inhibit the growth of new tree shoots.

Deforestation has many negative effects on the environment. The most dramatic impact is the loss of habitat for millions of species. Seventy percent of animals and plants inhabit the Earth’s forests and many cannot survive the deforestation that destroys their environment.

What problems does shifting agriculture generate?

Loss of soil fertility, forest fires, loss of biodiversity and alteration of environmental quality.

What is a tomb in agriculture?

What is the grave in agriculture? According to Sánchez (1981), slash and burn is defined as a system of crop field rotation, rather than crop rotation, with short harvest periods alternating with fallow or stubble periods, generally longer.

What is sedentary agriculture?

Sedentary rainfed agriculture has existed since the beginning of agricultural production techniques, when many peoples overcame nomadism and settled permanently in geographical areas with climatic conditions characterized by a lack of water.

What is traditional itinerant agriculture?

Itinerant-traditional agriculture. It is an agricultural system typical of tropical countries (in savannah and steppe formations) and equatorial countries (in jungles). It is characterized by being a traditional, subsistence agriculture, with few technical means. … SLASH-AND-BURN AGRICULTURE.

How does slash and burn affect agriculture?

When only annual crops are grown, the common result is land degradation. In the process, natural forests are decimated by extracting firewood and timber, or burned to make room for more crops. The typical consequences are soil depletion, species extinction, poverty and hunger.

Qué es la agricultura itinerante

El estudio de los sistemas agrícolas tradicionales supone una opción para la conservación de los ecosistemas naturales y el aumento de la producción de los cultivos. El sistema de tala y quema (RTQ) ha sido declarado obsoleto y perjudicial, pero esta perspectiva no es concluyente. El objetivo de este estudio es promover una mejor comprensión de su dinámica ecológica, que pueda orientar para la toma de decisiones del manejo racional de los ecosistemas donde se encuentra. Se analizó una cronosecuencia de barbecho del RTQ en un bosque tropical caducifolio sobre leptosoles, con el objetivo de describir la relación de las comunidades microbianas con el periodo de barbecho y la materia orgánica del suelo. Se reporta la diversidad funcional de las bacterias heterótrofas (índice de Shannon – H’) y su actividad, ya que el perfil metabólico de las poblaciones microbianas utilizando placas BIOLOG-ECOTM, el contenido de materia orgánica, el nitrógeno total, el nitrato, el amonio, el fósforo extraíble, la textura, la densidad aparente, la capacidad de campo y el punto de marchitez permanente. Las propiedades físicas del suelo fueron similares en todas las parcelas. El tiempo de barbecho afectó al pH, al contenido de materia orgánica y a los nitratos. No se encontró una relación clara entre H’ y el tiempo de barbecho (t), pero hubo diferencias significativas de H’ (p < 0,05) entre un tiempo de barbecho mayor y menor.
