The book adopts an application-oriented approach for ecorestoration of coalmine degraded. The theoretical aspects of ecorestoration, and steps involved in ecorestoration process and experimental aspects of thorough analytical procedures have been discussed in detail. It emphasizes on the types of mining, land degradation, and biodiversity conservation while giving details of technical and biological steps, topsoil management, selection of plant species, seeding, nursery practices; adoption of innovative approaches like mulching, biofertlizer application, hydroseeding, superabsorbent; use of grass-legume mix; monitoring and aftercare of reclaimed sites; the indicators of sustainable ecorestoration; and Rules and Acts implemented and followed across the world. Best ecorestoration practices, mine closure issues, collection, laboratory analysis and interpretation of minesoil and topsoil samples, monitoring biological parameters, litterfall and tree growth analysis, erosion management, design of drainage and sedimentation retention basin, and brief description of tree species with identifying character for field people are all part of the book. [Message by Prominent Academician] It is now urgent that methods of coal mining be integrated with engineering for ecorestoration because the larger society will not accept devastated waste land. A book, coming out from the hands of one of the persistent researchers of the field, cannot be more timely. Jayanta Bhattacharya, PhD FNAE Professor, Department of Mining Engineering Indian Institute of Technology, Kharagpur-721302, India.

This book is a comprehensive volume that brings together vast knowledge about agricultural prairies in one place, providing concise information and providing concise descriptions of natural resources and their influence on crop productivity. It provides detailed descriptions about natural settings as well as lucid discussions on soil fertility and crop production trends for various agricultural prairies distributed all across the earth. Chapters one through seven provide detailed descriptions on geologic aspects; physiography and agroclimate; natural vegetation and cropping history; human population, migration and development of settlements; natural resources such as soils, water, and crops; and environmental concerns. In particular, the first chapters cover the prairies of North and South America, namely, the Great Plains of North America, the Cerrado of South America, and the Pampas of South America. Chapter 4 deals with the steppes of Southern and Central Europe, Chapter 5 describes the savannahs of West Africa, Chapter 6 is concerned with Indo-Gangetic and Deccan plainsm, and Chapter 7 deals with prairies of Northeast China. The last chapter provides a comparative view of all agricultural prairies. Specifically, it compares the contrasting natural features, soil fertility, irrigation, and crop productivity. Agricultural prairies exist at levels of intensification. A few show subsistence or low input trends. Discussions pertaining to extent of intensification are included. Further, it includes interesting discussions on how the situation has grown into interdependence of man and prairies. It highlights the way prairies (crops) have influenced, naturally coaxed, and driven human activities to their own advantage.

Cyanoprokaryotes are probably the oldest organisms with plant metabolism. However, their cell structure and type of asexual reproduction prove their eubacterial origin. In spite of their existence from Precambrian onwards they have not lost their vitality, and still are able to colonize all possible biotopes, including very extreme environments (thermal springs up to 80 °C, rocks in extremely hot or cold deserts in both the tropics and Antarctica, hypersaline lakes and marshes, biotopes in volcanic regions, and other harsh habitats). This book is a review of all the cyanoprokaryotic taxonomic units, registered and recognizable from European natural biotopes, including the marine coasts. Our determination keys and taxonomic descriptions should permit the identification of natural populations, and should be related to known culture material. Numerous strains were isolated, kept in strain collections and used as important model organisms for experiments of various kinds. In culture only a few cyanoprokaryotes show the typical growth form known from nature, most others can be made to display their typical forms and life cycles by special procedures only. The identification of strains without previous knowledge of natural material needs to be carried out with special care. The aim of this book is to make possible the identification and standardization of known, morphologically and ecologically distinguishable cyanoprokaryotes that have been described from natural populations in Europe. Therefore, in the introductory part only data important for identification are presented. At the end of this chapter we append a list of basic literature, where all the detailed information necessary can be found. We have selected accurate drawings of the species described in the text. We also present illustrations of some non-European species if necessary for understanding the generic diacritical features or infrageneric diversity.

Wegen ihres Potenzials zur grundlegenden Veränderung ganzer Technologiefelder wird die Nanotechnologie als Schlüsseltechnologie angesehen. Sie wird in naher Zukunft nicht nur die technologische Entwicklung beeinflussen, sondern auch maßgebliche ökonomische, ökologische und soziale Implikationen mit sich bringen. Deutschland hält eine Führungsposition im Bereich der Nanotechnologie hinsichtlich der Forschungsaktivitäten und Fördermittel. Die hochaktuelle Studie, die vom Bundestagsausschuß für Bildung, Forschung und Technikfolgenabschätzung in Auftrag gegeben wurde, stellt eine umfassende Untersuchung zu Stand und Perspektiven der Nanotechnologie dar. Den Schwerpunkt der Studie bilden die vielfältigen konkreten Anwendungen und Anwendungsideen aus den unterschiedlichsten Bereichen.
