Shifting cultivation is known by many various names around the world, including "Slash-and-Burn Agriculture", "Swidden", and "Rotational Bush Fallow agriculture." Nearly 30% of the world's uplands from Africa, Latin America, Oceania, and South and Southeast Asia are covered by it and practiced in the wet tropics. It is the most prevalent kind of prehistoric land use on the planet and is found in hilly tropical regions, mainly in South and Southeast Asia, Africa, and the Americas. Since the beginning of the Neolithic period, which began around 7000 BC, this has been happening. Large swaths of various regions of the world continue to practice the practice. Scholars' perspectives on changing cultivation might vary greatly. While some see it as a wasteful and unprofitable practice, others believe it to be good for ecology and the ecosystem. Given the current situation, where the population is rapidly growing, the amount of land available per person is decreasing, and the climate change is a reality, it is high time we took a closer look to grasp the relevance of shifting agriculture.

1.1 GENERAL DESCRIPTION There is a folk tale from India which is mentioned under relevant situations. This tale teaches how different perspectives lead to different points of view. The tale of the blind men and an elephant originated in the ancient India, from where it has been widely spread to different parts of the world. This famous ancient tale mentions about six blind men who had never come in contact with an elephant during their lifetime and who know and visualize what the elephant appear like by touching it and feeling. In the tale it is highlighted that every blind man touches a different part of the elephant's huge body, but only one part, such as the leg, ear, tail, body or the tusk. These blind men then go on to narrate about the elephant on the basis of their touch and feeling and their recount of the elephant varied widely from each other. They were told that elephants could trample forests, carry huge loads and is very big in size. The six blind men were taken to the elephant and asked how it look like (Fig.1.1). The first blind man reached out and touched the side of the huge animal. "An elephant is smooth and solid like a wall!" he declared. "It must be very strong and powerful." The second blind man put his hand on the elephant's trunk. "An elephant is like a giant snake," he said. The third blind man felt the elephant's pointed tusk. "I was right," he decided. "This creature is as sharp and deadly as a spear." The fourth blind man touched one of the elephant's big ear and announced "I believe an elephant is like a huge fan or may be a magic carpet that can fly over mountains and treetops". The fifth blind man touched one of the four legs. "What we have here," he said, "is pillar of a house." The sixth blind man gave a tug on the elephant's coarse tail. "Why, this is nothing more than a piece of old rope and it appeared to him dangerous, indeed”.

2.1. GENERAL DESCRIPTION Forests covered only 31 per cent of the land in the world in 2011, while land used for agriculture, (cultivable land, perennial crops and pastures), covered 38 per cent (FAO 2011). In the history of humankind, agriculture is a recent invention (Mazoyer and Roudart, 2005). With the transition from the huntergatherer lifestyle to one of agriculture during the Neolithic Revolution, farmers quickly expanded their activity into forest areas. They developed shifting cultivation, an agricultural practice with temporal rotations in forest ecosystems. Shifting cultivation still exists today in tropical regions and is the livelihood basis for hundreds of millions of people (Mertz et al., 2009). The range in the population estimate is extremely wide, because of difficulties in counting smallholders spread out under the tree canopy at the margins of tropical forests, as also due to confusion that exists in differentiating shifting cultivators from other farmers involved in small-scale agriculture (Thrupp et al., 1997).

3.1 GENERAL DESCRIPTION Indigenous communities depending mainly on hunting, collection of food from the forests and managing natural resources to meet their requirements, have lived intimately with nature. Shifting cultivation has helped these communities to earn their livelihood for centuries to become to be food secure. Besides being a source of subsistence, the shifting cultivation has also been a repository of agro-biodiversity. Not considering this, the authorities have tried to impose the practice of intensive agriculture on indigenous people for conversion to mainstream agriculture (Singh et al. 2016). The way of life of indigenous people has been grossly impacted by the stress of market oriented development, government schemes, and interventions by some NGOs. The ‘dimensions of shifting cultivation’ not only includes the area under shifting cultivation and the number of shifting cultivators in the world but, various forms, shapes, methods and other aspects of the practice on spatial and temporal basis as well (Fig. 3.1).

4.1 General description Most temperate forest habitats support a small number of animal and tree species with wide geographic distributions, whereas the montane forests support a large number of species with narrow geographic distributions. "For mankind's most prevalent disease, we have a multiplicity of diagnoses, each provided with maximum casualness," Prof Galbrith writes in one of his publications. Poverty is a difficult situation to be in. It would be beneficial if we knew what was causing the problem. Obviously, there isn't a single answer. Many explanations are presented because they include a small amount of truth. However, one reason of poverty is pervasive: the historical or present link between land and people. Food, clothing, and shelter are all provided by the land. Poverty exists if these are not available." This statement by Galbrith, which is relevant for shifting agriculture areas with excessive rains and turbulent rivers, summarizes the genesis and cause of every responsible individual's considerable worry for good land management and soil maintenance. To round out the aspects of this issue, there is need to add 'environment' and 'ecology’ to this.

5.1 GENERAL DESCRIPTION As more is discovered about tropical soils, shifting cultivation has gained popularity as a symbol of change and showing "ingenious adaptations to unfavourable environments, based on a remarkably complete knowledge of local ecology and soil potential" (Allan 1972). The acidic tropical soils are found in about one billion ha of land in the World. Out of this, about 700 million ha of land is in the high rainfall tropics and, 300 million ha in the savanna, and practically all of it is in developing countries (IBSRAM 1987). The shifting cultivator lives in a humid tropical area with acidic soil. The use and protection of the forest to restore soil fertility is "at the heart of every agricultural system," and the tropics' swiddeners have devised a way that works (Benneh 1972). The integrated swiddener prefers field locations with existing mature forest, either "primary" or "secondary," because it recognises that it is vegetation which supply nutrients to the crop (Dove 1983a; Allan 1965; Rambo 1983; Posey 1983). The availability of nutrients to food crops increases after a burn, but these nutrients fast deplete due to leaching and erosion (Nye and Greenland 1960 and 1964). Nye and Greenland (1964) discovered the soil within the shifting cultivation to be quite variable due to fallen timber, termite mounds, and irregular ash distribution following the burning. These differences will be used to create microsites that will be planted with various crops based on the swiddeners' understanding of which crops benefit from rich soils and which are unaffected by poor soils. The field is left fallow after the cropping cycle is completed (typically 1 - 4 years), while tree crops may be harvested for years. If the site is not utilised for a long time, it will recover its fertility; if it is used too soon, degeneration will occur. It may be difficult to detect degeneration, particularly if it occurs gradually over multiple generations. It's especially tough with Shifting cultivators since they "look to be so self-sufficient, so well integrated with their surroundings" (Street 1969). The assumption is that the longer the land is left fallow, the greater the soil recovery will be. The system should be sustainable if extended fallows can be maintained. Shifting cultivators’ response to the requirement to produce food without using manures, fertilisers, or alluvial deposition is soil replenishment by fallowing (Greenland 1974). The technique works if a long fallow time is maintained; if the fallow period is shortened, soil fertility falls. Shifting agriculture is considered environmentally sound while population pressure is mild, but it is environmentally damaging when land scarcity precludes a long enough fallow interval to recover soil productivity. It's crucial to distinguish between traditional shifting cultivation and shifting agriculture in a state of disequilibrium (Watters 1971).

6.1 general description Between 13,000 and 3,000 BC, Neolithic period, mountain people in Asia, Africa, and Latin America have practiced shifting cultivation (Mazoyer and Roudart 2006). A cultivation phase, consisting of removing forest and crop production for 1 to 3 years, is followed by a fallow phase, in which agriculture is discontinued to allow soil nutrients to recoup (Conklin 1961). Conklin (1961) distinguished between total and partial shifting cultivation. Pioneer shifting cultivation, in which primary or apex forest is cleared annually, and replaced by shifting cultivation, which entails clearing mostly secondary forests, are both essential forms of cultivation that are primarily practised for farmers' subsistence. Partial shifting cultivation, on the other hand, is done as a supplemental or temporary activity (Conklin 1961). Throughout history, indigenous peoples have used fire to manage their land and natural resources. Pastoralists and hunters-gatherers in Africa's savannas, for example, have used fire to preserve the ecosystem's productivity for livestock and game for millennia (McClanahan and Young 1996). In pre-colonial times, indigenous peoples in North America also significantly altered the landscape, establishing and preserving pastures and open forest savannas through regulated burning (Pyne 1982, cited in: Schneider 2000).

7.1 General Description Shifting cultivation is a type of land use that dates back to the dawn of agriculture. It's done in places where forest resources are still plentiful. It usually refers to the gradual transformation of primary forests into a mosaic of secondary forests at varying stages of growth, rather than the complete abolition of forests. However, primary forest removal occurs gradually in order to preserve the same fallow time despite population development. As no primary forests remain (or as the remaining primary forests are entirely protected by local customs or conservation legislation), secondary forests fade away, and new techniques arise or are adopted, the fallow period shortens. Natural capital is gradually replaced by man-made productive capital, or the system approaches a state of crisis, depending on whether the limitations to these changes can be levered. In theory, the new land uses allow for more forest protection because they require less territory to provide the same output. In practice, they are triggered or triggered by a series of more radical changes, such as infrastructure development, migrations, financial investments, and new consumer habits, all of which frequently end in large-scale deforestation.

8.1 General Description Based upon ethnic values and culture, both private and common property land tenure regime is found in existence in the shifting cultivation system. In Odisha state of India, shifting cultivation locally called as podu, there exists both private and common property regime (Dash 2006). In case of Meghalaya state, while the private land ownership pattern does exist among the Khasi and Karbi tribes, the Garo tribes, on the other hand, resort to community land ownership pattern (Deb et al., 2013). Furthermore, an ethno-agrarian economy based on shifting cultivations is self-sufficient, and such shifting cultivators typically rely on outside sources for alleviation of their economic demands very infrequently, if at all (Gupta 1994). The use of human labour is the key input in the shifting cultivation system and the practice of mutual exchange of labour amongst these shifting cultivator communities is also not uncommon. In practices like harvesting, the groups of families join hands together to harvest the crop of each plot one by one. This practice of community labouring reduces drudgery and increases work productivity. During this harvesting time, it is said that farmers exchange their innovations and look at each other’s innovations as they work. Further, it is customary to arrange food and drinks by the family of the plot which is being harvested. The community recognizes these harvest periods as festive events which makes their work enjoyable. The case of village named Nawalparasi, Nepal, shows that shifting cultivators work in an innovative way in their community in which the part of the village land is set aside and is cultivated by the members of whole community jointly. The benefit they harvest from this area is used to fund for teachers’ salaries in community school (kerkhoff and Sharma 2006). Further, the close knit and kinship ties are not only necessary for labour sharing but also important for technology diffusion among the members (NAEB 2008). The division of labour exists between men and women. It varies from place to place. The Manipur shifting cultivation characteristics portray that the women predominate in seed selection and planting, weeding and other operations, the activities like cutting of the trees in jungle, clearing, burning are generally done by men Both men and women participate in harvesting of produce and so harvested produces are carried to the villages by head loading.  

9.1 General Description Education can help farmers in impoverished nations move away from environmentally damaging slash-and-burn agriculture (Nganje et al. 2001). The goal of their study was to see how much extension education can help people embrace agricultural strategies other than slash and burn. In Cameroon, farmers' cropping patterns are modelled as a function of farm size, farmer educational level, and extension professional visits, whether slash and burn, varied crops, or monocropping. According to the data, higher extension visiting rates reduce not just the risk of farmers choosing slash and burn agriculture, but also encourage them to switch to monocropping. Because monocropping is a trend toward export-oriented agriculture in Cameroon, it may help to promote greater economic development in Western Africa (Nganje et al. 2001). Continued extension education activities are therefore vital in decreasing the environmental damage caused by slash and burn agriculture while also encouraging the adoption of more profitable cropping strategies. The negative impacts of shifting cultivation on the environment as farmers strive to provide for higher populations and the associated decline of shifting cultivation into an unproductive system have led most governments in Southeast Asia to perceive it as a backward method of cultivation (Thanh and Vien 2017). Consequently, governments throughout the region have tried to ban shifting cultivation. In Malaysia, for example, huge development programmes have been implemented to improve shifting cultivators livelihoods when they abandon shifting cultivation (Majid, 1983). The government of Laos has enacted land-use and forestry policies aiming at expanding forest cover, eliminating shifting farming, and supporting intensive commercial agriculture (Castella et al., 2013). For many years, the Vietnamese government has implemented strict rules and procedures to combat shifting cultivation. These include a large-scale programme called 'Fixed Cultivation, Fixed Residence' (officially known as Resolution No. 38/CP), which aims to permanently settle 'shifting fields' and 'shifting people' (McElwee, 2004), as well as a forestlandallocation policy that ties people to specific plots of land, effectively making shifting cultivation impossible (Castella et al., 2005).

10.1 General Description The soil, water, and biodiversity of the land make up a complex composition. Together, these three components produce goods and services that lay the groundwork for people to live sustainably and in peace with one another. Yet an estimated 3.2 billion people's security, livelihoods, and health are at stake due to land degradation. Any decrease or loss in the biological or economic productive capability of the land resource base is referred to as "land degradation." Natural processes contribute, but humans are primarily to blame for the harm. Degradation is frequently intricately connected to biodiversity loss and the effects of climate change. Restored lands provide access to clean water, reduce erosion, preserve livelihoods and biodiversity, create forest products, and supply biomass fuel. Trees in agricultural environments can enhance soil fertility, hold onto moisture, and boost food output. Trees and forests slow climate change by storing carbon; intensive restoration efforts may lead to a reduction in the atmospheric concentration of carbon dioxide. Restoration can assist communities in adjusting to the effects of climate change by ensuring water supplies or reducing the effects of severe storms. Plant cultivation was only a modest activity of primarily nomadic populations in the second millennium BC, and it had little impact on the vegetation. After 0 BC/AD, sedentary civilizations created enormous settlement mounds, and on the dunes, a shifting agricultural system with fields and fallows was constructed. Park savannas, an agroforestry system with protected wild fruit trees scattered throughout the fields, were used for cultivation (Höhn and Neumann 2012). Extensive farming with protracted fallow periods was conducted during the first millennium AD. The composition of the woody vegetation changed as fallow seasons shrunk and the impact of cattle herding on the vegetation increased towards the start of the second millennium AD. The substantially lower species richness of the contemporary woody forest was eventually brought about by declining precipitation and anthropogenic pressure (Höhn and Neumann 2012).
