  • Development Or Despoilation? - Krishnakumar
    Andaman Islands: Development or Despoilation? - Krishnakumar DEVELOPMENT OR DESPOILATION? The Andaman Islands under colonial and postcolonial regimes M.V. KRISHNAKUMAR Jawaharlal Nehru University, New Delhi <[email protected]> Abstract The last quarter of the 19th Century marked an important watershed in the history of the Andaman Islands. The establishment of a penal settlement and an Imperial forestry service, along with other radical changes in the islands’ traditional economy and society, completely transformed the basic pattern of their forest resource use and entire system of forest management. These colonial policies, directly or indirectly, had a drastic impact on the indigenous population and island ecology. This article analyses the sources of environmental change in the Andaman Islands by examining the general ecological impacts of the state initiated development programmes. It also analyses the ‘civilising missions’ and forestry operations undertaken by British colonial administrators as well as the Indian state’s development initiatives under the ‘Five Year Plans’ that followed Indian independence in 1947. Keywords Andaman Islands, forestry, development, environmental change, Andaman tribes Introduction On December 26th 2004 a tsunami triggered by an earthquake off the south east coast of Sumatra swept across the Indian Ocean swamping many low-lying coastal areas and causing death, destruction of properties and infrastructure and despoliation of crops. Amongst those territories worst affected by the surge were the Andaman and Nicobar Islands. When Indian prime minister Dr Manmohan Singh visited the islands in the immediate aftermath of the flooding he identified that the project to reconstruct and rehabilitate coastal areas of islands provided the opportunity for a ‘New Andamans’ in which sustainable agriculture and fishery enterprises could exist in harmony with the natural environment.

  • The Andaman Islands Penal Colony: Race, Class, Criminality, and the British Empire*

The Andaman Islands Penal Colony: Race, Class, Criminality, and the British Empire* C LARE A NDERSON School of History, Politics and International Relations University of Leicester University Road, Leicester LE1 7RH, UK E-mail: [email protected] ABSTRACT: This article explores the British Empire’s configuration of imprisonment and transportation in the Andaman Islands penal colony. It shows that British governance in the Islands produced new modes of carcerality and coerced migration in which the relocation of convicts, prisoners, and criminal tribes underpinned imperial attempts at political dominance and economic development. The article focuses on the penal transportation of Eurasian convicts, the employment of free Eurasians and Anglo-Indians as convict overseers and administrators, the migration of “volunteer” Indian prisoners from the mainland, the free settlement of Anglo-Indians, and the forced resettlement of the Bhantu “criminal tribe”.It examines the issue from the periphery of British India, thus showing that class, race, and criminality combined to produce penal and social outcomes that were different from those of the imperial mainland. These were related to ideologies of imperial governmentality, including social discipline and penal practice, and the exigencies of political economy. INTRODUCTION Between 1858 and 1939, the British government of India transported around 83,000 Indian and Burmese convicts to the penal colony of the Andamans, an island archipelago situated in the Bay of Bengal (Figure 1).

  • Arachnozoogeographical Analysis of the Boundary Between Eastern Palearctic and Indomalayan Region
    Historia naturalis bulgarica, 23: 5-36, 2016 Arachnozoogeographical analysis of the boundary between Eastern Palearctic and Indomalayan Region Petar Beron Abstract: This study aims to test how the distribution of various orders of Arachnida follows the classical subdivision of Asia and where the transitional zone between the Eastern Palearctic (Holarctic Kingdom) and the Indomalayan Region (Paleotropic) is situated. This boundary includes Thar Desert, Karakorum, Himalaya, a band in Central China, the line north of Taiwan and the Ryukyu Islands. The conclusion is that most families of Arachnida (90), excluding most of the representatives of Acari, are common for the Palearctic and Indomalayan Regions. There are no endemic orders or suborders in any of them. Regarding Arach- nida, their distribution does not justify the sharp difference between the two Kingdoms (Paleotropical and Holarctic) in Eastern Eurasia. The transitional zone (Sino-Japanese Realm) of Holt et al. (2013) also does not satisfy the criteria for outlining an area on the same footing as the Palearctic and Indomalayan Realms. Key words: Palearctic, Indomalayan, Arachnozoogeography, Arachnida According to the classical subdivision the region’s high mountains and plateaus. In southern Indomalayan Region is formed from the regions in Asia the boundary of the Palearctic is largely alti- Asia that are south of the Himalaya, and a zone in tudinal.

  • LIFE HISTORY of PACHLIOPTA RHODIFER Das (Oberthiir), Papilio Mayo Atkinson, Or Pachliopta Rhodifer (Butler)
    Journal of the Lepidopterists' Society 48(2), 1994, 111-120 LIFE HISTORY OF PACHLIOPTA RHODIFER (PAPILIONIDAE: TROIDINI) K, VEENAKUMARI AND PRASHANTH MOHANRAJ Central Agricultural Research Institute, P. B. No. 181, Port Blair, 744101, Andaman Islands, India ABSTRACT. The Andaman c1ubtail, Pachliopta rhodifer (Butler), is one of, three papilionids endemic to the Andaman and Nicobar islands, India. This elegant red-bodied swallowtail, with its unique red spatulate tail, previously was known only from the imago. We detail the life history of this species and discuss implications for butterfly conservation in these islands. Additional key words: Aristolochiaceae, butterfly conservation, Andaman Islands, Nicobar Islands, India. The Andaman and Nicobar islands have been identified as one of the provinces of the Indomalayan biogeographic realm requiring urgent attention to ensure adequate protection of their disltinctive biological communities (Anonymous 1985, ICBP 1992). These islands are situated in the Bay of Bengal, Indian Ocean, between 6-14°N latitude and 92- 94°E longitude, and consist of 306 islands. They stretch over 700 km and occupy a total area of 8249 km2 (Anonymous 1986). The Andamans are separated from the Nicobars by the Ten Degree Channel, a distance of about 100 km. The two island groups have characteristic biotic elements, with each island group harboring a set of unique endemics (Anonymous 1986, Rao 1986). On the basis of the number of endemics found in a region, Collins and Morris (1985) rate the Andaman and Nicobar islands sixteenth out of a total of 51 critical swallowtail faunas worldwide. In spite of the high priority ranking, no attempt has been made to study the life histories, food plants, and other requirements of Graphium epaminon­ das (Oberthiir), Papilio mayo Atkinson, or Pachliopta rhodifer (Butler), the three endemic papilionids that are thought to be confined to Great Andaman (which includes the three neighboring islands of North, Mid­ dle, and South Andaman).

  • Flaked Glass Tools from the Andaman Islands and Australia
    Flaked Glass Tools from the Andaman Islands and Australia ZARINE COOPER AND SANDRA BOWDLER BETWEEN THE FIFTEENTH AND NINETEENTH CENTURIES, Europeans colonized many parts of the world that were already occupied by other people. Many of the previous landholders were people using stone-based technology. In the longer term, they were generally unable to hold their land in the face of invasion by people with metal and gunpowder technology. In the shorter term, however, there was often a period during which the indigenous people maintained their traditional lifestyle, but adapted elements of the new culture to its pursuance. One example of such adaptation is the use of glass to produce tools of a kind pre­ viously made out of stone by means of percussion, a technique known as flaking or knapping. Flaked glass artifacts dating to a period of culture contact between stone-flaking cultures and glass-producing cultures have been recorded in several countries. In this paper we discuss examples from the Andaman Islands and Western Australia to show how cultures with no historical relationship but a similar tech­ nological base made similar adaptive uses of a new material. While these exam­ ples are drawn from societies that survived into recent historical times with hunter-gatherer economies, it is possible that any culture with a knapping tech­ nology could have made similar adaptations. PROBLEMS OF IDENTIFICATION There is a problem in the identification of flaked glass artifacts, as noted by Beaumont (1961) for South Mrica. As he and earlier writers whom he cites point out, physical characteristics identical with those derived from human trimming are easily produced on fractured glass by accidental means.
