This book explores the relationship between climate change–induced migration and conflict in Bangladesh – one of the most ecologically fragile countries in the world. It explores why people migrate from their original place of land and how the migration of people with a different background to an ethnically distinctive region due to environmental changes can become a source of conflict and violence between the host peoples and migrants. The volume focuses on the Chittagong Hill Tracts (CHT), which has experienced long-standing ethnopolitical conflict due to the settlement and migration of the Bengali people from the plain land of Bangladesh. This settlement and migration were mainly caused climatic events such as floods, cyclones, sealevel rise, and disasters. It traces the history of the ethnic conflict in the region and presents key findings from the field, as well as the dynamics of everyday politics in the region. This volume also highlights how internally climate-displaced people generate violence and civil strife in the major urban cities through their settlements in slums. The volume will be of great interest to scholars and researchers of environmental studies, human geography, migration and diaspora studies, public policy, social anthropology, and South Asian studies.

Anabas testudineus (Bloch, 1792) is locally known as koi, familiar to people for its exceptional taste. Although koi is listed by IUCN as data deficient, its abundance in natural water bodies of Bangladesh is reduced at a severe scale in comparison to a decade before. Considering the present biodiversity status of A. testudineus in nature, the author conducted this work for conservation of the genetic resources of the fish through cryopreservation of spermatozoa. The book will explain different steps in sperm cryopreservation protocol chronologically which can be applied further in relevant fish species.

Migration is an unavoidable continuous process from the very beginning of civilization which has been considered as an important livelihood strategy for both rural and urban population. It also plays an important role (positive or negative) in the development of any country. In developing countries like Bangladesh, migration to cities creates more hazards in development. So, it is important to assess the socio-economic conditions of migrants and their causes. This study focuses this issue and recommends some policy which plays an important role for further advanced research. Clearly, it would be very helpful for policy makers, program designers to design or redesign programs or existing programs considering the identified risk factor of migration to cities in Bangladesh.

Due to the environmental and economical concerns, it is expected that a huge number of wind farms are going to be connected with the existing networks in the near future. However, the wind being intermittent sources of power, cannot meet the load demand all of the time. Wherever intermittent power sources reach high levels of grid penetration, energy storage becomes one option to provide reliable energy supplies. Therefore, this book deals with different approaches to stabilize a grid-connected wind farm.Among the various energy storage devices SMES is one of the options to provide reliable and fast response energy to the grid. These devices can help to make renewable energy more smooth and reliable, though the power output cannot be controlled by the grid operators. They can also balance micro grids to achieve a good match between generation and load demand. Also, it can significantly improve the load availability, a key requirement for any power system. The energy storage, therefore, is a desired feature to incorporate with renewable power systems, particularly in stand alone power plants. Thus this book investigates different methods to use SMES for stabilizing windfarm.

Industrial estate is an increasing source of pollution. The aim of study was assessment of pollution of Mongla Industrial Estate & its impacts on health and socio-economic Status in BD. These experiments give a result that in water polluting industry BOD (1190 mg/l), COD (4330 mg/l) and TDS ( 8840 mg/l) are very high and pH (2.23) shows very acidic in nature of the effluent of MSFPI. Air pollution is severe in this area, at the ball mill (MCF) SPM was 520 g/m3, & ambient air of area contains 510 g/m3 of SPM. Noise level at ball mill average 100 dB. These values do not meet the DoE std. & affects the workers & people in vicinity of estate. 39%, 23%, 17%, 13% are suffered by skin diseases, diarrhea, typhoid, dysentery respectively. 32%, 30%, 7%, 25%, 5% of people are suffered by breathlessness, wheezing, bronchitis, asthma and allergy respectively. 31%, 23%, 21%, 14% of people are suffered by sleeping problem, headache, heart pain, blood pressure respectively. The treatment cost of the people is 7% of their yearly income. About 59%, 11%, 30% of people are industrial labor, farmers and other type of workers respectively.

The genus of Botrytis is a fungus that causes botrytis blight or gray mold fungal disease in much herbaceous plant. Botrytis has a several species and Botrytis cinerea is the most common among them. It can be epidemic when rainy, drizzly weather continues several days. It causes botrytis gray mold in chickpea resulted crop loss up to 95%. B. cinerea isolates were characterized in terms of cultural, morphological, physiological and pathogenic aspects and showed significantly variations on media. B. cinerea grew well at 20 C and pH 4.5, respectively. Luxuriant growth and the quickest sclerotia initiation were obtained on CDA medium. B. cinerea exhibited different reaction of highly susceptible to resistant to a set of chickpea cultivars. Among the 7 tested fungicides, Bavistin, CP-Zim, Sunphanate and Rovral were the most effective to inhibit the radial growth of B. cinerea at a lower concentration. This book would be helpful for the professional researchers, undergraduate and graduate students to determine the cultural, morphological, physiological and pathogenic variability of B. cinerea isolates and to make them some suggestions to the field levels for its appropriate management.
