Ecological Environment: A New Perspective
In coastal aquifers, saltwater intrusion may cause serious consequences in terms of both environmental and economic impacts. An attempt has been made in the present study to elucidate the quality of groundwaterin the study area in terms of the chemical parameter change due to the seasonal variation of water level. The present study deals with the physio-chemical characteristics of groundwater quality in Nagapattinam district.The study area showed generally similar hydrochemical characteristics slightly higher level of Cl-, Na+, and EC was observed. Based on the Cl- , Na+ and EC data, the groundwater falls within high salinity.
Ravine Lands: Greening for Livelihood and Environmental Security
This book, the only one of its kind on ravine lands, reflects the significant advances made over the past two decades in our understanding of gully erosion, its controlling factors, and various aspects of gully erosion. It also addresses central research gaps and unanswered questions, which include historical studies on gully erosion to better understand the different stages of their formation; appropriate measuring techniques for monitoring or assessing the geological and hydrological parameters and processes involved in gully development; interaction of hydrological and other soil degradation processes; ecology and biodiversity of fragile ravines; impact of climate and environmental change...
Allelopathy in Crop Production
Allelopathy offers great potential: (a) to increase agriculture production (food grains, vegetables, fruits, forestry), (b) to decrease harmful effects of modern agricultural practices (multiple cropping, leaching losses from N – fertilizers, indiscriminate use of pesticides viz. weedicides, fungicides, insecticides and nematicides and development of pesticides tolerant /resistant biotypes in pests) on soil health/productivity and on environment and (c) to maintain soil productivity and pollution free environment for our future generations. It is hoped that in the near future the allelopathy may be used in crop production, crop protection, agroforestry and agro-horticultural systems of developed countries. Therefore, it may be one of the strategies to increase agricultural production in Sustainable Agriculture of 21st century. This book is based on the research findings and addresses to various intricate problems of crop production, to which there was no definite answer in the past but now have been attributed to allelopathy.
Orchids of Eastern Ghats (India)
The book gives complete details of Orchids of Eastern Ghats in India. Brief details of Eastern Ghats, its geology, soils, climate etc, have been given at the beginning. A bracketed key to the genera and key to the species have been given. It is followed by systematic enumeration. A total of 197 taxa belonging to 66 genera of Orchidaceae have been systematically enumerated. Under each species, Citation according to latest ICN, synonyms to connect to National and regional floras, type, etymology, detailed description, Flowering and fruiting season, habitat, distribution (World, India, Eastern Ghats) and specimens examined have been given. All the references about orchids of Eastern Ghats have been given at the end. The essence of this book is the coloured Photographs for all the species available in Eastern Ghats. Line diagrams have also been given for some species. Endemic and Threat categories have also been mentioned. Index to genera and species has been given at the end.
Climate, Environment and Disaster in Developing Countries
The world is currently experiencing changes in climate and environment that often lead to natural disasters. Nearly three million people worldwide may have been killed in the past 20 years by natural disasters. In total, 90% of the natural disasters and 95% of all disaster-related deaths occur in the developing countries. Recently such problems have accelerated due to LULC change, biodiversity degradation, increased tourism, urbanization and climate change. This book, consisting of 27 chapters, explores the topics of climate, environment and natural disasters in developing countries. It is essential to discuss these diverse issues in the field of geography as it encompasses interdisciplinary...
Forestry Principles And Applications
This textbook is written for undergraduates & postgraduates, university & college teachers, scientists and professional foresters. It offers a real-life introduction to the field of forestry and an interdisciplinary overview of the theory behind it. This textbook covers forestry in great depth and the real strength of the book lies in its focus on the context and applications of the field. Thanks to its wide scope, it not only serves as a useful introduction to the field but can also be used to understand how many other key forestry topics have changed in recent years as a consequence of the technology advancement. This textbook will significantly help the students for preparation of UPSC-Civil Service Exam, UPSC-Indian Forest Service Exam, ICFRE & ICAR Scientists/NET Exam, University Entrance Exam for admission to M.Sc. and Ph.D. programmes.
Textile Manufacturing Processes
Textile manufacturing is an important subject in textile programs and processing industries. The introduction of manmade and synthetic fibers, such as polyester, nylon, acrylic, cellulose, and Kevlar, among others, has greatly expanded the variety of textile products available today. In addition, new fiber development has brought about new machines for producing yarns, fabrics, and garments. Textile Manufacturing Processes is a collection of academic and research work in the field of textile manufacturing. Written by experts, chapters cover topics such as yarn manufacturing, fabric manufacturing, and garment and technical textiles. This book is useful for students, industry workers, and anyone interested in learning the fundamentals of textile manufacturing.
Coastal Ecosystems
This volume incorporates theoretical and practical knowledge through case studies and reviews to serve as a baseline of information for coastal ecosystem research, and discusses the impacts of pollution, industrialisation, agriculture and climate change on coastal ecosystem biogeochemistry and biodiversity. The case studies address the role of coastal ecosystems as a carbon sink which is getting impacted by anthropogenic disturbances. Through this analysis, the book covers various strategies for the conservation and management of coastal ecosystems, considering their unique ecological and biogeochemical attributes and region-specific threats and impacts. The book will be of interest to a wide range of readers including students, researchers and professionals in coastal ecosystem science, coastal pollution, climate change adaptation, biodiversity conservation and environmental management.
