The current global environmental crisis is primarily the result of non-standardized parameters for environmental regulation, and is impacting e.g. clean air, safe drinking water and the quality of food, particularly in developing nations. Due to their poor/lax execution of EIA protocols, newly developing countries are preferred destinations for establishing pollution-emitting industries, which results in the degradation and depletion of their natural resources. Lack of environmental policy intervention is another major incentive to base “dirty” industries in these nations. In order to ensure sustainable development, the highest-priority issues include the monitoring and eradication of environmental problems stemming from economic development; virtually every form of economic development primarily results in the loss of forests and thus biodiversity, followed by declining air quality and the contamination of natural resources. Sustainable development ensures responsible interactions with the environment, so as to minimize the depletion or degradation of natural resources and preserve environmental quality. It involves integrated approaches to understanding the importance of environmental management systems and policy measures that lead to improved environmental performance. This book addresses the environmental concerns associated with economic development, and with approaches to attaining sustainable economic development, which include monitoring the quality of water resources, soil erosion and degradation of the natural environment.

The National Botanical Research Institute came into being as the 13th among a chain of National Laboratories established during April, 1953 under the Council of Scientific and Industrial Research by the Govt. of India for advanced research in fields of specialisation which have a direct bearing on socio-economic, industrial and scientific advancement of the nation. Christened initially as National Botanic Gardens, the nucleus around which the institution took shape under its founder- Director Late Prof. K. N. Kaul, was a large herbarium of Indian flora and a centu- old botanical garden spread over 35 ha of land on the banks of River Gomti in the heart of Lucknow city. It’s a matter of great pleasure and profound satisfaction to me that a Golden Jubilee volume entitled, “Pteridology in the New Millennium” is being published and released during the Golden Jubilee year of NBRI in the honour of Professor B. K. Nayar who laid the foundation of the Pteridology Laboratory of the NBRI, which is now a well equipped laboratory for the study of Indian pteridophytes. Professor Nayar is a holistic Botanist as evident through his contributions and publications in almost all the areas of study of Pteridophyta. The contribution of Professor Nayar towards the development of modern Pteridology and the role of NBRI in it is indeed great and very important. His publications will be valuable for the younger generation of scientists in the field as well as for the more mature research workers and teachers.

This work is a comprehensive information on the indigenous bioresources of North Eastern India with the scope of bioprospecting for discovery and commercialization of new sources and products and long-term ecological balance. The exploration, conservation and sustainable utilization of bioresources of world’s Megabiodiversity Hotspots are undeniable. North Eastern India is a recognised biodiversity hot spot where the evolutionary forces are at its optimum, making this region as centre of origin for many species. Although little bit exploratory studies have been conducted in this part of the globe but a scientific exploitation of the bioresources is almost lacking. Unscientific exploitation and overexploitation without proper knowledge of the bioresources may lead to imbalanced ecosystem of this mega diversity region. At the same time, very less exploration and exploitation will hamper biodiversity based development. Today, unscientific dramatic changes are underway in this region. Human activities are changing, degrading and destroying the bioresources in an unplanned manner. Scientific bioprospecting of the bioresources will boost the economy while ensuring conservation. This book offers comprehensive information about various levels of bioprospecting of the gene pool of this Indo-Burma Mega Biodiversity Hot Spot, the North East India, which is endowed with huge biodiversity potential for exploration and exploitation for the benefit of humankind. Also, this book highlights the less and merely explored part of the indigenous biodiversity of North East India with explanation towards their better sustainable exploitation for benefit of the people, economy and environment. The novelty of the book lies in expert coverage of the bioresources of this mega-diverse region including plants, microbes, insects etc. with provisions for their sustainable scientific utilization. This book portrays North East India as a melting pot of bioresources which are little explored and also those resources which are still to be explored. The book mainly highlights the bioprospecting approaches for North East Indian bioresources, and thus, it make itself a unique one in filling the knowledge gap that is there regarding the bioprospecting of the biodiversity of this special region on the earth. The book concludes by the ecotourism potential of this region. The target audiences for this book include biodiversity economists who are working on technology and bioresource management issues, and especially on biotechnology and biodiversity, development economists addressing the issues of bioresources in developing countries. These people may be in academia, in government, in non-governmental organizations and in private companies. The other target audiences group is policy scholars in government/public sectors who are interested in issues of biotechnology, IPRs, and biodiversity. In addition, scholars/experts in both development studies and resource management studies form another group of target audiences. Also, the book will be useful for the interaction between developed and developing nations regarding the issues of biodiversity and bioprospecting, as North Eastern India is the hub of Biodiversity.
