Printed at: Maitry Off set Press Masangally, Kathmandu, Nepal Tel.: 4230840 Foreword Alien species that become invasive are considered to be main direct drivers of biodiversity loss across the globe. Management of invasive alien species (IAS) is seen as major challenge in the field of biodiversity conservation. IAS, the non-native species threaten ecosystems, destroy habitats and create problems to other native species through invasion. It is considered as the second greatest agent of species endangerment and extinction. The ecological cost is often the irretrievable loss of native species and ecosystems. It also causes heavy economic loss, in terms of reduced crop and livestock production, reduced native biodiversity, increased production costs and so forth. Nepal is also suffering from the introduction of IAS. Chitwan National Park, the first national park in the country listed in the world heritage site has been invaded with Micania macarantha in the last decade threatening the habitat of some of the global significant species inhabiting the park. It is degrading the habitat of rhinoceros and prey species of tiger, thus reducing the resource base of these keystone species. Similar problems of invasion of non-native alien species are witnessed in eastern Terai, mid-hills and even in the high Himalayas. The protected areas (PA) in Nepal are under huge pressure from poaching and illegal activities and the invasion have further compounded pressure to the PA management. Research, monitoring, and management of biological invasions have not yet been a priority in Nepal. Very limited works have been initiated but these activities are not well coordinated. In this context, NTNC initiated to organize the International Conference on Invasive Alien Species Management (ICIASM) with an aim to provide valuable input while revising National Biodiversity Strategy (NBS). We are thankful to Asian Development Bank (ADB) and the USAID funded Hariyo Ban Program for providing financial support for the conference. The conference, through the Chitwan Declaration attracted attention of global community for the effective management of IAS in a coordinated manner. The conference has also noticed the negative impacts of IAS not only in agriculture, livestock productivity, forests, wetlands, and water scarcity but also in fisheries, wildlife conservation, and human health. The conference has urged for the urgent need of comprehensive national strategies for prevention. It has been a special platform to discuss over the IAS issues in the globe and needs to be continued in the days to come. At the end, I would like to extend our sincere thanks to all of the agencies and individuals involved to make the conference successful. Thanks to NTNC’s BCC, technical committee, and management committee for the effective management of the conference. Special thanks to all of the delegates from Australia, India, Nepal, Pakistan, South Africa, United Kingdom, and United States of America for their valuable presence and sharing. Thank you, Govinda Gajurel Member Secretary National Trust for Nature Conservation Preface Invasive Alien Species (IAS) pose a profound impact on humans as well as on the ecosystems as it can be a cause of heavy economic loss, in terms of reduced crop and livestock production, reduced native biodiversity, costs involved to control their rapid spread and impacts on human health. Thus, these non-native species destroy ecosystems, habitat, or species and are also the second greatest agent of species endangerment and extinction after habitat destruction. Flora and fauna have entered an age of globalization just like economic globalization. Species are being moved around the planet at a rate much greater than we ever expected. The issue of IAS is caused by human activities associated with global linkages, network and ease of access by road, rail or air. In order to control their spread, measures have to be taken at national and local level. Realizing the threat of biological invasion, more attention has been given on research, monitoring, control and management of invasive species in the recent years by global communities. The Convention on Biological Diversity (CBD) calls for its signatory nations to prevent the introduction, control or eradication of those alien species. The different bioclimatic zones of Nepal favor the introduction of several alien species. Research, monitoring and management of biological invasions have not yet been a priority in Nepal. Very limited works have been initiated and, moreover, these activities are not well coordinated. On the other hand, there is no national strategy document for the scientific management and control of invasive species. In this context, National Trust for Nature Conservation (NTNC) organized the International Conference on Invasive Alien Species Management (ICIASM) at NTNC’s Biodiversity Conservation Center (BCC), Sauraha, Chitwan National Park from March 25–27, 2014 with an aim to provide valuable inputs while revising National Biodiversity Strategy (NBS) and implementing other biodiversity conservation and management initiatives.Major financial support for the conference was provided by the Asian Development Bank (ADB) and the USAID funded Hariyo Ban Program. The conference provided a good platform and opportunity to present and share research findings, outcomes, recommendations and innovative ideas regarding IAS management all over the globe.The international character of this conference is illustrated by the participation of representatives from Australia, India, Nepal, Pakistan, South Africa, United Kingdom and United States of America. 27 research papers were presented by the participants in the conference. In addition, the conference, through Chitwan Declaration, agreed to draw attention of global community to initiate joint management to control spread of IAS. The conference also drew attention to the negative impacts of IAS not only in agriculture, livestock productivity, forests, wetlands, and water scarcity but also for fisheries, wildlife conservation and human health and urged for the urgent need of a comprehensive national strategy for prevention. This proceeding contains the collection of key note paper and technical papers presented at the conference and it is intended to demonstrate how different dimensions of IAS problems impinge on each other and to provide recommendations to counteract and deal with the current and future IAS management problems and challenges. Opinions and statistics included in the technical papers do not necessarily reflect the opinion and views of organizer and supporting agencies. Last, but not the least, I would like to extend my sincere gratitude to all the conference participants, agencies and individuals, institutions who provided financial support, members of technical and management committees and entire NTNC team for their support and cooperation to make this conference successful.

    13 SACRAMENT AS A CULTURAL TRAIT IN RAJVAMSHI COMMUNITY OF NEPAL Prof. Dr. Som Prasad Khatiwada Post Graduate Campus, Biratnagar [email protected] Abstract Rajvamshi is a local ethnic cultural group of eastern low land Nepal. Their traditional villages are scattered mainly in Morang and Jhapa districts. However, they reside in different provinces of West Bengal India also. They are said Rajvamshis as the children of royal family. Their ancestors used to rule in this region centering Kuchvihar of West Bengal in medieval period. They follow Hinduism. Therefore, their sacraments are related with Hindu social organization. They perform different kinds of sacraments. However, they practice more in three cycle of the life. They are naming, marriage and death ceremony. Naming sacrament is done at the sixth day of a child birth. In the same way marriage is another sacrament, which is done after the age of 14. Child marriage, widow marriage and remarriage are also accepted in the society. They perform death ceremony after the death of a person. This ceremony is also performed in the basis of Hindu system. Bengali Brahmin becomes the priests to perform death sacraments. Shradha and Tarpana is also done in the name of dead person in this community. Keywords: Maharaja, Thana, Chhati, Panju and Panbhat. Introduction Rajvamshi is a cultural group of people which reside in Jhapa and Morang districts of eastern Nepal. They were called Koch or Koche before being introduced by the name Rajvamshi. According to CBS data 2011, their total number is 115242 including 56411 males and 58831 females. However, the number of Rajvamshi Language speaking people is 122214, which is more than the total number this group.
  • History of the Gurkhas

    History of the Gurkhas

    Sheet 2 History of the Gurkhas Gurkhas have been part of the British Army for almost 200 years, but who are these brave fighters? Gurkhas are people from Nepal. According to a legend, they got their name from a warrior saint, Guru Gorkhanath, who lived 1200 years ago. He had predicted that his people would become world famous for their bravery. The word Gurkha also comes from the name of a city, Gorkha, in western Nepal. Britain tried to invade Nepal when it was trying to conquer the northern parts of India. The British soldiers had fine rifles whilst the Ghurkas were armed only with their traditional knives called Kukris. But the Nepali soldiers were such courageous and clever fighters that the British soldiers could not defeat them, After six months of fighting, Britain decided to make peace with Nepal. The British army began to recruit Gurkha soldiers because they wanted them to fight on their side. Since that day, the Ghurkas have fought alongside British troops in every battle across the world. Nepal became a strong ally of Britain. One hundred thousand Gurkhas fought in the First World War. They fought and died in the battlefields of France in the Loos, Givenchy, Neuve Chapelle and Ypres as well as many other countries. Again the whole of the Nepali army fought for Britain during the Second World War. There were 250,000 Gurkha in total. The were used by the British to put down revolts in India. Gurkhas fought in Syria, North Africa, Italy, Greece and against the Japanese in Singapore and in the jungles of Burma.

KOHL! 019eas Invasive Alien Plants An Ecological Appraisal for the Indian Subcontinent FSC ...wesc.org MIX Paper from responsible sources `FSC C013604 CABI INVASIVE SPECIES SERIES Invasive species are plants, animals or microorganisms not native to an ecosystem, whose introduction has threatened biodiversity, food security, health or economic development. Many ecosystems are affected by invasive species and they pose one of the biggest threats to biodiversity worldwide. Globalization through increased trade, transport, travel and tour- ism will inevitably increase the intentional or accidental introduction of organisms to new environments, and it is widely predicted that climate change will further increase the threat posed by invasive species. To help control and mitigate the effects of invasive species, scien- tists need access to information that not only provides an overview of and background to the field, but also keeps them up to date with the latest research findings. This series addresses all topics relating to invasive species, including biosecurity surveil- lance, mapping and modelling, economics of invasive species and species interactions in plant invasions. Aimed at researchers, upper-level students and policy makers, titles in the series provide international coverage of topics related to invasive species, including both a synthesis of facts and discussions of future research perspectives and possible solutions.

Two authentic samples, (3S,3′S)- and meso-stereoisomers 1b and 1c, were chemically synthesized according to the method previously developed for (3R,3′R)-alloxanthin (1a). Application of this method to various alloxanthin specimens of aquatic animals demonstrated that those isolated from shellfishes, tunicates, and crucian carp are identical with (3R,3′R)-stereoisomer 1a, and unexpectedly those from lake shrimp, catfish, biwa goby, and biwa trout are mixtures of three stereoisomers of 1a–c. Keywords: carotenoid; alloxanthin; synthesis; chiral HPLC separation; absolute configuration 1. Introduction Alloxanthin (1) (Figure 1) was first isolated from Cryptomonas algae [1] and its structure was determined to be 7,8,7′,8′-tetreradehydro-β,β-carotene-3,3′-diol by MS, IR and 1H-NMR spectroscopies [2].
