History Of

Two major earthquakes in 1897 and 1950 had a deep impact upon the environment and humans in north-east India. The massive seismic disturbance of 1897 played a crucial role in shaping the physical history of this region. Seismologists have observed that this earthquake holds a 'prominent place among the great earthquakes of the world'. Another earthquake in 1950 disturbed the region's physical setting. This article will examine how these earthquakes transformed the landscape of Assam, and, in so doing, affected the lives and livelihoods of human communities. It will detail the various geological and hydrological consequences of earthquakes, which included the creation of floods, landslides, fissures, sand vents and artificial river dams. It will demonstrate how these changes affected Assamese agriculturalists and fishing communities. In so doing, it will shift the historiography of earthquakes away from a largely urban focus to examine the rural experiences of seismic activity.

Insight Into

North- East India is an under veiled region with an awe-inspiring landscape, different groups of ethnic people, their culture and heritage. Contemporary writers from this region aspire towards a vision outside the tapered ethnic channel, and they represent a shared history. In their writings, the cultural memory is showcased, and the intensity of feeling overflows the labour of technique and craft. Mamang Dai presents a rare glimpse into the ecology, culture, life of the tribal people and history of the land of the dawn-lit mountains, Arunachal Pradesh, through her novel The Legends of Pensam. The word ‘Pensam’ in the title means ‘in-between’,  but it may also be interpreted as ‘the hidden spaces of the heart’. This is a small world where anything can happen. Being adherents of the animistic faith, the tribes here believe in co-existence with the natural world along with the presence of spirits in their forests and rivers. This paper attempts to draw an insight into the culture and gender of the Arunachalis with special reference to The Legends of Pensam by Mamang Dai.

Background: Duck farming plays a significant role, next to chicken in the socio-economic uplift men of the rural farmers of North-East India. Pati duck is the most common duck breed in the Brahmaputra valley of Assam and the other common variety reared in North-East India is Chara-Chambeli, however it originatein Kerala. Genetic characterization plays a significant role for formulation of breeding strategies for improvement of any breed. Microsatellites are codominant in nature and are highly polymorphic. High level of allelic variation, co-dominant mode of inheritance and potential for automated analysis make them an excellent tool for genotyping, mapping and genetic characterization. Pati duck is the most common duck breed in the Brahmaputra valley of Assam and the other common variety reared in North-East India is Chara-Chambeli however its origin in Kerela. Therefore, the present investigation was carried out to characterize these two duck breeds using microsatellite markers to evaluate the genetic diversity in these two duck population. Methods: For the present study, Blood sample were collected from 50 Patiducks and 50 Chara-Chambeli ducks from different parts of North-East India. Assessment of genetic characterization of duck breeds of north-east region were carried out using 16 microsatellite markers and population genetics analysis were done by POPGENE software. Result: In the present study, all the studied loci were highly polymorphic. Analysis generated a total of 41 microsatellite alleles. The number of observed alleles (Na) with an overall mean of 1.93±0.258. However, the effective number of alleles (Ne) with a mean of 1.6933±0.2712. The Shannon’s information index was found to a mean value of 0.5685±0.1693. The overall means for observed (HO) and expected (He) heterozygosities were 0.2889±0.2477 and 0.5289±0.0853, respectively. The chi-square (χ2) test for Hardy-Weinberg equilibrium revealed that all the loci are in within Hardy-Weinberg equilibrium.

Corporate Social Responsibility has become a mainstream global business strategy in recent years and a large number of firms in the world issue numerous activities as a part of it. India is one of the first among few countries in the world to have a CSR act and the first to bring about legislation to implement CSR activities.The Government of India has made two significant interventions in the field of CSR-- in 2010, it made compulsory for public as well as private enterprises to spend 2 to 5 percent of their net profit on CSR; and it amended the Companies Act, 1956 that made compulsory provision for CSR under Section 135 in 2013. In this context this article is an attempt to discuss the progress in CSR initiatives in India over the years.

Economic Ties

With the emergence of globalization, the need for economic integration has been realized by the international communities and lately by the Less Developed Countries (LDCs). Most of the countries both developed and less developed, have reoriented their development strategies to improve their growth performance by integrating their economies with the world economy. In this process, India has experienced some significant changes and the country is identified as one of the fastest growing economies in the world. In this direction, India’s Look East Policy is worth mentioning. Under this policy, India seeks economic cooperation with the ASEAN  and its neighbouring countries through North-Eastern Region (NER) of the country

This paper is an attempt to study the inter-state border disputes in north-east India with special reference to Assam-Nagaland border conflict in the border areas of Golaghat district. The north-east region of India comprising of eight states has been gradually transforming into a conflicting area that breaks the harmony between the states and also undermines the concept of north-east India as a prosperous and culturally rich region of India. Due to some social, political and economic issues, this north east India divided into various states which were under the same umbrella at a time. Several inter-state disputes take place in this region with the upcoming of political and social unrest. The Naga insurgency that started in the late 1950’s is known as one of the unresolved armed conflicts in India. So, through this paper the researcher makes an attempt to study how the recent Naga-Assamese clash happened in the border areas of Golaghat district is responsible for breaking down of communal harmony, humanity, and inter-state peace process. As the dispute between Assam and Nagaland is currently the most prominent with a history of violent clashes between border areas, this paper aims to concentrate mainly on this issue. Moreover this paper will try to examine the role of the government regarding the above issue. Thus the above issues will be highlighted in the paper.

Global warming is contentious and difficult to measure, even among the majority of scientists who agree that it is taking place. Will temperatures rise by 2ºC or 8ºC over the next hundred years? Will sea levels rise by 2 or 30 feet? The only way that we can accurately answer questions like these is by looking into the distant past, for a comparison with the world long before the rise of mankind. We may currently believe that atmospheric shifts, like global warming, result from our impact on the planet, but the earth's atmosphere has been dramatically shifting since its creation. This book reveals the crucial role that plants have played in determining atmospheric change - and hence the conditions on the planet we know today. Along the way a number of fascinating puzzles arise: Why did plants evolve leaves? When and how did forests once grow on Antarctica? How did prehistoric insects manage to grow so large? The answers show the extraordinary amount plants can tell us about the history of the planet -- something that has often been overlooked amongst the preoccuputations with dinosaur bones and animal fossils. David Beerling's surprising conclusions are teased out from various lines of scientific enquiry, with evidence being brought to bear from fossil plants and animals, computer models of the atmosphere, and experimental studies. Intimately bound up with the narrative describing the dynamic evolution of climate and life through Earth's history, we find Victorian fossil hunters, intrepid polar explorers and pioneering chemists, alongside wallowing hippos, belching volcanoes, and restless landmasses.
