Photographs of major NTFP species. References. In India, Non Timber Forest products (NTFP) provide about 40 percent of total official forest revenues and 55 percent of forest-based employment. Nearly 500 million people living in and around forests depend on NTFPs as a critical component for their sustenance. It is now felt increasingly that management and development of NTFP resources is essential for various reasons. First, forest management focused on the production of NTFPs may be ecologically and economically sustainable provided that extraction rates do not exceed the maximum sustainable yield. Tribal communities have been involved in NTFP utilization for centuries without destroying the resource base. Managing forests for production of NTFPs also implies maintaining biological diversity of both plant and animal species. In one estimate it is suggested that up to 35 percent of the income of tribal households in India comes from the collection of unprocessed NTFPs. Also, since NTFPs involve a large variety of seasonal products, returns are frequent and relatively continuous. Though NTFP has become very important for social and commercial economies in developing countries but only timber production received major management attention. Now, rising commercial as well as social demands and high market prices of NTFPs have resulted in their large scale exploitation. Exploitation is generally being done without caring for the sustainability of the species and the ecosystem. More over the knowledge about planned, scientific and sustainable exploitation of majority of the species is lacking. As such many of them have become endangered, vulnerable and threatened. Some have reached extinction, threshold or might have become extinct. Considering NTFPs contribution in rural economy and livelihood of rural communities as a whole in the country and Uttarakhand in particular, the present book focuses on policy formation, research and management issues for ensuring sustainable development of these resources.…

Hardcover. Zustand: New. 1st Edition. Fisheries science is the academic discipline of managing and understanding fisheries. It is a multidisciplinary science, which draws on the disciplines of limnology, oceanography, freshwater biology, marine biology, conservation, ecology, population dynamics, economics and management to attempt to provide an integrated picture of fisheries. In some cases new disciplines have emerged, as in the case of bio-economics and fisheries law. Methods in Fisheries Science & Aquatic Ecology is a text book targeted for UG (B. Sc, B. F. Sc. Degree courses) and PG (M. Sc, M. F. Sc., Degree and Diploma courses) students studying Ichthyology or Fish and Fisheries (General, Applied) or Fishery Science or Aquatic Ecology as a subject in the traditional or Agricultural Universities of India. The large part, especially the content on fishery and to great extent habitat ecology is suitable for use by the students of marine ecology and fishery science as these methods are common in fresh and marine water, both. In respect of ecology, salinity is an additional factor. The book has two sections A) Field and Laboratory Techniques in Limnology/Aquatic Ecology or Biology/Aquatic Environment/ and B) Techniques in Fishery Biology/Science. Both sections cater to fresh and marine water. The methods described in the book can be directly used for carrying out a practical exercise. New practical exercise(s) can be taken up from the book and included in the syllabus, both at UG and PG level or related Diploma courses. Since the book provides methods on water analysis and fishery science at one place, it is also a suitable reference book for researchers getting introduced to the field of fishery and environmental science, as well. …

Propagation technology of Bamboo. 6. Management of bamboo stand. 7. Post harvesting technology of bamboo. 8. Bamboo preservation. 9. Market and socio-economics of bamboo. References. Bamboo occurs in greatest abundance and variety in the South and South-East Asian countries. India has the distinction of being the second highest bamboo producing country after China. Beside its diverse uses as fuel, food, fodder, fiber, small timber, paper and pulp, cottage industry and construction, it is ideal species for conserving soil, moisture, and protecting river banks and nallas. these are very fast growing grass species having high carbon sequestration potential. Being poor man's timber it is one of the important forest species distributed throughout the country as a source of income for millions of rural people for sustaining their livelihood. The objective of this book is to provide guidelines for bamboo resources, propagation and management. Efforts were made by many institutions to develop farmers friendly, cost effective, easy propagation technologies of bamboos. Keeping in view the non availability of seeds for growing planting stock, the main emphasis is given to popularize farmer's friendly propagation technologies of bamboo developed by Forest Research Institute Dehradun for promoting bamboo plantations in the country which will help in employment and income generation for rural masses.
