What is shifting cultivation

Shifting cultivation is an This technique is often used in In shifting agriculture, after two or three years of producing vegetable and grain crops on cleared land, the migrants abandon it for another plot. Land is often cleared by slash-and-burn methods—trees, bushes and forests are cleared by slashing, and the remaining vegetation is burnt. The ashes add potash to the soil. Then the seeds are sown after the rains. Political ecology [ ] Shifting cultivation is a form of Fallow fields are not unproductive. During the fallow period, shifting cultivators use the The relationship between the time the land is cultivated and the time it is fallowed are critical to the stability of shifting cultivation systems. These parameters determine whether or not the shifting cultivation system as a whole suffers a net loss of nutrients over time. A system in which there is a net loss of nutrients with each cycle will eventually lead to a degradation of resources unless actions are taken to arrest the losses. In some cases The longer a field is cropped, the greater the loss of 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. People unused to living in forests cannot see the fields for the trees. Rather they perceive an apparently chaotic land...

Many of us do not know what is shifting cultivation what are its disadvantage, so, today we will discuss on this topic. So instead of looking elsewhere for this answer, stay here, and read the post completely, you will get the answer. Agriculture is the art and science of cultivating soil, growing crops, fruits, vegetables, flowers, and rearing livestock. It has the practice of plant and animal products for the people to use and their distribution to markets. Moreover, ⅔ of the Indian population is dependent on agriculture. Agriculture is basically divided into types based on the style of crop cultivated, the scale of cultivation, the passion for cultivation, the level of mechanization, livestock combinations, and how farm produce is distributed. What is shifting cultivation what are its disadvantage? In shifting cultivation, a plot of land is cleared by felling trees and burning them. Then, the ashes are mixed with the soil and crops. Shifting cultivation is also known as Slush & Burn agriculture. Therefore, the indigenous populations of Northeast India frequently use shifting agriculture, also known as “Jhum” as a method of agriculture. Today we will discuss one of the segments of agriculture, shifting agriculture. What Is Shifting Cultivation What Are Its Disadvantage? Wondering What is shifting cultivation what are its disadvantage, you should know about shifting cultivation. A traditional farming technique known as “shifting cultivation,” or “ Jhum cultivation,” entai...

Read on to learn about this agricultural system. Shifting cultivation definition Shifting cultivation, also known as swidden agriculture or slash-and-burn farming, is one of the oldest forms of subsistence and extensive agriculture, particularly in tropical regions (it is estimated that about 300-500 million people globally carry out this type of system) 1,2. Shifting cultivation is an extensive farming practice and refers to agricultural systems in which a plot of land is temporarily cleared (usually by burning) and cultivated for short periods of time, then abandoned and left in fallow for more extended periods of time than that during which it was cultivated. During the fallow period, the land reverts to its natural vegetation, and the shifting cultivator moves on to...

Shifting cultivation is generallypracticed in the thickly forested areas. These are the areas of heavy rainfall and quick regeneration of vegetation. A plot of land is cleared by cutting the trees and burning them. The ashes are then mixed with the soil. After the soil loses its fertility, the land is abandoned and the cultivator moves to a new plot. The major disadvantage of Shifting Cultivation is that many trees in the forest are cut and this increases soil infertility and leads to soil erosion.

This article is based upon work conducted by FAO under the genera/heading "Alternatives to Shifting Cultivation in the Use of Forest Land". A major part of this effort has consisted of case-studies - all in Africa - which have been conducted by the Overseas Development Institute (United Kingdom), the Department of Forestry of Wageningen Agricultural University (the Netherlands), the Institut de recherches d'agronomie tropicale et de cultures vivrières (Paris), the Forest Division of the Silviculture Research Station (Dar es Salaam) and the Forest Products Research Institute (Kumasi, Ghana). SHIFTING CULTIVATION IN SUMATRA forest-burning planting and abandonment What is shifting cultivation? How much area does it cover? How many people are involved? These questions are addressed here in an attempt to bring some clarity and precision to the subject of shifting cultivation and long-fallow agriculture, one of the most widely discussed topics in forestry today. In the literature referring to shifting cultivation, either the term is not clearly defined or its definition varies greatly from one author to another. These differences can be attributed but only in part - to the diversity of countries, areas, or communities being studied. In a regional or global review of the subject, it i...

Views: 53,582 What is Shifting Cultivation Shifting Cultivation is a form of farming, where farmers cultivate the land temporarily for two or three seasons. Then they abandon the land and leave it to allow vegetables to grow freely. After that, farmers move to a different place. They leave the place when the soil gets out of fertility or land is overrun by weeds. The cultivation time is generally less than when the ground is allowed to regenerate fertility. There is still the use of shifting farming in India. That is being used in the hilly areas of the North-Eastern Region, Andhra Pradesh, Sikkim, Bihar, Orissa, Madhya Pradesh, Tamil Nadu, Maharashtra, Kerala and Karnataka. How is Shifting Cultivation Practiced? It is a way of farming long followed in the humid tropics of southeast Asia, Sub-Saharan Africa, and South America. In Shifting agriculture in India, farmers would cut and burn the native vegetation. Then they sow crops in the ash-fertilized and exposed soil for 2 or 3 seasons in succession. Characteristics of Shifting Cultivation • It is ecologically viable if enough land for long (about 10 to 20 years) is restorative. • The demand and need for food should not be too high. • This system is suited for harsh environmental conditions and fragile ecosystems of the tropics. • And that is the reason we have only limited success in finding viable alternatives to Shifting agriculture in India. Types of Shifting Cultivation The different types of shifting agriculture are ...

But information about such landscapes is urgently needed to improve the outcomes of global earth system modelling and large-scale carbon and greenhouse gas accounting. This study combines existing global Landsat-based deforestation data covering the years 2000 to 2014 with very high-resolution satellite imagery to visually detect the specific spatio-temporal pattern of shifting cultivation at a one-degree cell resolution worldwide. The accuracy levels of our classification were high with an overall accuracy above 87%. We estimate the current global extent of shifting cultivation and compare it to other current global mapping endeavors as well as results of literature searches. Based on an expert survey, we make a first attempt at estimating past trends as well as possible future trends in the global distribution of shifting cultivation unt...
