Why is shifting cultivation sustainable?
When the soil’s fertility is exhausted, the tribe moves on and clears another small area of forest. The original area is regenerated, as it receives nutrients and seeds from surrounding vegetation. As no lasting damage occurs, this method of agriculture is sustainable.
Is shifting cultivation is a sustainable form of agriculture?
Shifting cultivation is a traditional, sustainable method of agriculture which has been practised by indigenous tribes for centuries. It occurs in areas of the Amazon rainforest, Central and West Africa and Indonesia.
Why was shifting cultivation good?
There are a number of benefits that urge farmers to choose a practice of shifting cultivation in their agricultural plan. In well-controlled shifting cultivation, a small plot of land is cleared and the vegetation is used to provide nutrients to the soil. The soil remains fertile for a few years to allow farming.
What is a sustainable farming alternative to shifting cultivation?
Agroforestry systems which substitute nutrient cycling between tree and crop layers for burning of woody biomass (in shifting cultivation systems) or use chemical fertilizer (modern cropping systems) as a means of maintain productivity, can be a more sustainable alternative.
Who uses shifting cultivation?
Shifting cultivation is one of the oldest forms of subsistence agriculture and is still practised by millions of poor people in the tropics.
Is shifting agriculture good or bad?
Shifting cultivation systems are ecologically viable as long as there is enough land for long (10–20 years) restorative fallow, and expectations of crop yield and the attendant standards of living are not too high. These systems are naturally suited for harsh environments and fragile ecosystems of the tropics.
What are the major problems of shifting cultivation?
Challenges to shifting cultivation include unseasonal and erratic rainfall, reduction in duration of fallow period due to pressure on land, reduction in yields due to decline in soil fertility, lack of interest among the younger generation in practicing it among others.
How do you stop shifting cultivation?
Forest Department personnel tried to use their knowledge of forestry to stop or reduce shifting cultivation by bringing the land under forest cover. For this, they implemented schemes like Social Forestry and National Afforestation Programme for tree plantations on jhum lands.
What are the negative effects of shifting cultivation?
Eventually, increased agricultural usage may lead to substantial loss of soil fertility, and consequently cropping conditions in the former dense woodland will no longer be superior to those in the open woodland.
What is the disadvantage of shifting agriculture?
– The primary disadvantage of shifting cultivation is cutting down of forest, which further leads to deforestation. – Shifting cultivation is also known as slash and burn agriculture, whereby a farmer clears down vegetation by burning down forest, an easiest way to prepare a land for cultivation.
What are two reasons why shifting cultivation is expected to diminish during the twenty first century?
(1) Shifting cultivation is expected to diminish because many new agricultural techniques and inventions such as genetically enhanced seeds, plows, tractors, irrigation systems, and many other things have made other types of agriculture more efficient.
What is the importance of shifting cultivation?
The secondary forests created by shifting cultivation are commonly richer in plant and animal resources useful to humans than primary forests, even though they are much less bio-diverse. Shifting cultivators view the forest as an agricultural landscape of fields at various stages in a regular cycle.
How was shifting cultivation Practised?
Shifting cultivation is an agricultural system in which a person uses a piece of land, only to abandon or alter the initial use a short time later. This system often involves clearing of a piece of land followed by several years of wood harvesting or farming until the soil loses fertility.
Is shifting cultivation a sustainable farming?
How does shifting cultivation affect the environment?
Shifting cultivation has been attributed to causing large-scale deforestation and forest degradation in tropical forest-agriculture frontiers. This view has been embedded in many policy documents in the tropics, although, there are conflicting views within the literature as to the impacts of shifting cultivation.
Where is shifting cultivation practiced?
In large parts of humid West Africa, shifting cultivation is still widespread—with the exception of Nigeria, where it has all but disappeared and remains present only in small pockets.
Is shifting cultivation bad?
Now, shifting cultivation is bad because it causes carbon emission and thus contributes to climate change. Recent research has however also provides evidence to the contrary. 1. Shifting cultivation is not a major cause of deforestation.
Is shifting cultivation legal?
Shifting cultivation, an age-old practice in parts of India, may soon get legal backing, with the government planning to define land use that will enable such cultivators access credit and agriculture-related benefits including subsidies.
Why was hifting cultivation sustainable in the past?
The response received 1 point in part C for explaining that “[s]hifting cultivation was sustainable in the past because there weren’t as many people, so there was plenty of land that was available for the practice.”
Which is an example of shifting cultivation in the past?
Slash-and-burn agriculture is then offered as an example of shifting cultivation. The response received 1 point in part C for explaining that shifting cultivation was sustainable in the past “because there was a larger amount of farmland available” and there were fewer people.
How is shifting cultivation related to sustainable intensification?
There is a need to transform shifting cultivation to sustainable intensification. The latter implies managements that produce more per unit area, time, and energy inputs. The goal is to restore soil quality, replace what is removed, and respond wisely to what has been changed by natural and anthropogenic perturbations.
Why is shifting cultivation expected to diminish during the twenty-first century?
Explain two reasons why shifting cultivation is expected to diminish during the twenty-first century. Reasons (2 points) Explanation (2 points) Technological advancements (e.g., fertilizers, hybrid seeds, pesticides) • Leads to increased yields/food quantity
What crops are grown in shifting cultivation?
Commonly, crops such as corn, millet, and sugarcane, are grown using shifting cultivation. An additional trait for shifting cultivation is that the farmers do not own the land they grow on. Rather, the chief of the village or an organized council owns the land and decides what happens.
Why is shifting cultivation expected to diminish?
The diminishing of shifting cultivation in the twenty-first century has been a major change in agriculture. New environment policies imposed by the government has been a primary reason for this. Government policies have been restricting deforestation, or the clearing of trees and other vegetation.
