Adivasi in the context of "List of Scheduled Tribes in Odisha"

The Scheduled Castes (SCs) and Scheduled Tribes (STs) are officially designated groups of people and among the most disadvantaged socio-economic groups in India. The terms are recognized in the Constitution of India and the groups are designated in one or other of the categories. For much of the period of British rule in the Indian subcontinent, they were known as the Depressed Classes.

In modern literature, many castes under the Scheduled Castes category are sometimes referred to as Dalit, meaning "broken" or "dispersed". The term was popularised by the Dalit leader B. R. Ambedkar during the independence struggle. Ambedkar preferred the term Dalit over Gandhi's term Harijan, meaning "people of Hari" (lit. 'Man of God'). Similarly, the Scheduled Tribes are often referred to as Adivasi (earliest inhabitants), Vanvasi (inhabitants of forest) and Vanyajati (people of forest). However, the Government of India refrains from using these terms that carry controversial connotations. For example, 'Dalit', which literally means 'oppressed', has been historically associated with notions of uncleanness, carries implications of the concept of untouchability. Similarly, 'Adivasi', which means 'original inhabitants', carries implications of native and immigrant distinctions and also perpetuates the stereotypes of being civilized and uncivilized. Therefore, the constitutionally recognized terms "Scheduled Castes" (Anusuchit Jati) and "Scheduled Tribes" (Anusuchit Janjati) are preferred in official usage, as these designated terms are intended to address socio-economic disabilities, rather than to reimpose those social stigmas and issues. In September 2018, the government issued an advisory to all private satellite channels asking them to refrain from using the derogatory nomenclature 'Dalit', though rights groups have come out against any shift from 'Dalit' in popular usage.

In India, social classification based on caste has its origin in ancient times. It was transformed by various ruling elites in medieval, early-modern, and modern India, especially in the aftermath of the collapse of the Mughal Empire and the establishment of the British Raj. Caste is traditionally associated with Hinduism, but is more pervasive in extent: an estimated 98% of contemporary Indians, including Hindus, Muslims, Christians, Sikhs, Buddhists, and Jains, identify with a caste.

Beginning in ancient India, the caste system was originally centered around varna, with Brahmins (priests) and, to a lesser extent, Kshatriyas (rulers and warriors) serving as the elite classes, followed by Vaishyas (traders and merchants) and finally Shudras (labourers). Outside of this system are the oppressed, marginalised, and persecuted Dalits (also known as "Untouchables") and Adivasis (tribals). Over time, the system became increasingly rigid, and the emergence of jati led to further entrenchment, introducing thousands of new castes and sub-castes. With the arrival of Islamic rule, caste-like distinctions were formulated in certain Muslim communities, primarily in North India. The British Raj furthered the system, through census classifications and preferential treatment to Christians and people belonging to certain castes. Social unrest during the 1920s led to a change in this policy towards affirmative action.

The medical ethnobotany of India is the study of Indian medicinal plants and their traditional uses. Plants have been used in the Indian subcontinent for treatment of disease and health maintenance for thousands of years, and remain important staples of health and folk medicine for millions. Indians today utilize plants for both primary medical care (principally in Rural and undeserved areas) and as supplementary treatment alongside modern medical science. It is estimated that 70% of rural Indians use traditional plant based remedies for primary healthcare needs. This reliance of plants for medicine is consistent with trends widely observed in the developing world, where between 65% and 80% of people use medicinal plant remedies.

Herbal medicine in India is largely guided by folk medicine, both in codified cultural practices shared widely (Ayurveda, Siddha, Unani), and highly localized practices unique to individual tribes or tribal groups (Adivasi). Between 3,000 and 5,000 species of medicinal plants grow in India with roughly 1,000 threatened with extinction. Of these, more than 2,400 plant species have been documented for medicinal use.

Thaker is an Adivasi tribe of Maharashtra, India. This tribe was originally living in hilly areas of Maharashtra and is now also found scattered all over the Maharashtra state of India.(Not to be confused with Thakar)

The West Rapti, also known as the Kuwano, is a river which drains Rapti Zone in Mid-Western Region, Nepal, then Awadh and Bhojpur-Purvanchal regions of Uttar Pradesh state, India before joining the Ghaghara. It is a major left bank tributary of the Ganges, and is also known as the Karnali in Nepal.

The West Rapti is notable for janajati ethnic groups – Kham Magar among its highland sources and then Tharu in Inner Terai Deukhuri Valley, for its irrigation and hydroelectric potential, and for recurrent floods that led to its nickname "Gorakhpur's Sorrow".
