This book comprising seven parts is organized under two sections. The first section deals with environment containing four parts, whereas the second section, containing three parts, is on energy. The first part deals with some aspects of hydrologic impacts of global warming and anthropogenic changes. Part II is on bio-environment and discusses plants, biomass, and bacterial species. Part III focuses on chemical environment. Section one is concluded with Part IV on social environment. Section two starts out with Part V on solar energy. Hydropower is discussed in Part VI. The concluding Part VII deals with biogas. The book will be of interest to researchers and practitioners in the field of water resources, hydrology, environmental resources, agricultural engineering, watershed management, earth sciences, as well as those engaged in natural resources planning and management. Graduate students and those wishing to conduct further research in water and environment and their development and management may find the book to be of value.

Now greatly expanded and completely updated, this ever popular work includes over 700 magazines in 69 subject categories, from Abstracts and Indexes to Women's Interests. The entries include date of establishment, issuing agency or authority, bibliographical data, and a concise review of the publication. Appendices provide a basic list of magazines for small- to medium-size libraries, magazines outstanding for their illustrations, magazines useful for career and vocational guidance, and magazines indexed in periodical indexes and abstracts.

This book is the compilation of research papers and review articles contributed by the eminent scientists and research workers. There are articles on the various groups of plants,bacteria ,fungi,algae,lichens,pteriodophytes and phanerogams,particularly on their diversification in relations to humon welfare. Pteridophytes in soil conservation of genetic resources,aquatic edibles, pharmacognosy of drug-plants, diversification of algae and lichens,phytodiversity of wetland and grassland are some of the fascinating and informative articles of this volume. The book in its totality,contains useful information for the postfraduate students,teachers and researchers dealing with applied botany,genetics, microbiology and environmental biology.

Weeds are variously defined as plants growing where they are not wanted, plants that interfere with human activity. Weeds affect everyone in the world by reducing crop yield and quality, delaying or interfering with harvesting, interfering with animal feeding, reducing animal health, preventing water flow, as plant parasites, etc. It is estimated that those problems cause $ billions worth of crop losses annually and the global cost of controlling weeds also runs into many $ billions every year. Atlas of Weed Mapping presents an introductory overview on the occurrence of the most common weeds of the world. The book notably includes: Description of cropping practices and explanations for the global distribution of weeds Invasive plant mapping Aquatics and wetland plants with histological plant details Theoretical and practical aspects of weed mapping Aspects on the documentation of herbicide resistance Biodiversity, rare weeds and the dominance of the most common weeds Fully illustrated with more than 800 coloured figures and a number of tables, this new characterisation of anthropogenic vegetation will be interesting for readers of a great number of disciplines such as agriculture, botany, ecology, geobotany and plant community research. More than a hundred experts have contributed data to this unique compilation.
