This book presents a fascinating, ethnographic account of the challenges faced by communities living in Majuli, India, one of the largest river islands in the world, which has experienced immense socio-environmental transformations over the years, processes that are emblematic of the Brahmaputra Valley as a whole.Written in an engaging style, full of the author's insider perspectives, this insightful volume explores the processes of flooding and riverbank erosion in Majuli, including re-configuration of the island's geographies, loss of local livelihoods, and large-scale displacement of the population. The book begins with an examination of the physical geography of Majuli and its ecological complexities, leading to discussion on the role of the state in water governance and hazard management, as well as popular resistance by the rural communities on the island. The book focuses on livelihoods as a way of offering economic context to living in challenging environmental conditions and examines the interactions between the state and a whole host of non-state actors, and the everyday, arbitrary functioning of the bureaucracy in a hazardscape.This volume is an invaluable resource for scholars interested in political ecology of hazards and vulnerability, water and hydraulic infrastructure, rural livelihoods and agrarian questions, state theorizations, island studies, and resistance and social movements, as well as those with an interest in northeast India more generally across various disciplines.

Plants are autotrophs and sessile, while animals are heterotrophs and motile. Sessility has imposed on plants 94% hermaphroditism, 23% selfing, 3% polyploidization and 39% clonality, in comparison to < 5% herma-phroditism, < 1% selfing and 2% clonality in motile animals. Whereas plants consist of 374,000 species but 1,664 variety/species, animals comprise 1,543,196 species and 210 variety/species. Hence, plants have undergone variety diversity, while animals have species diversity. In animals and plants, the species ratio is reduced from 4.1 animals : 1.0 plant to 1.4 for pollinating animals : 1.0 pollinated plants. In pollination, animals are benefited dietarily but plants are cross pollinated, generating new gene combinations - the raw material for evolution and speciation. For the reduced species diversity in plants, reasons are traced to 90% hermaphroditism, ~ 23% selfing and 39% clonality. Clonality decreases from 100% in 6-7 tissue typed sponges and 3 tissue typed algae drastically to 0.7% in 60 tissue typed worms but gradually to ~ 23% in 60 tissued typed angiosperms. About 12-15, 5-8 and 77-80% of all animal and plant species are distributed in marine, freshwater and terrestrial habitats, respectively. Animals have conserved the 'right' sequence of gametogenesis but plants have gone through a 'wrong' sequence prior to settling with right one albeit with double fertilization in angiosperms. Both animals and plants are 80% male heterogametics. Only 0.5% of them can afford semelparity. While 20 and 57% angiosperms are perennial trees and herbs, annual herbs make up 23% only. In all of them, 85, > 19 and < 1% are pollinated by fast flying animals, wind and water, respectively. Increasing pollen load enhances fruit- and seed-set. In contrast to animals, the life cycle of plants is direct but complicated. Unlike animals, plants have greatly contributed to weathering of rocks and the atmospheric gas composition during the geological past. From dormant spores and seeds of plants, life can be restored after thousands of years.

William Curtis (geb. 11. Januar 1746 in Alton, Hampshire; gest. 7. Juli 1799 in Brompton) war ein englischer Botaniker, Apotheker und Entomologe. Sein offizielles botanisches Autorenkürzel lautet Curtis.Die Pflanzengattung Curtisia Ait. aus der Familie der Hartriegelgewächse (Cornaceae) ist nach ihm benannt worden.Curtis war Vorsteher des Chelsea Physic Garden. Er gründete botanische Gärten in Bermondsey, 1771 in Lambeth und 1789 in Brompton. 1787 begründete Curtis das Botanical Magazine und war bis zu seinem Tod dessen Herausgeber.

Die von meiner Mutter ererbte Vorliebe zum Raritätensammeln beeinflusste schon in der Schule die Wahl des einzigen mir naheliegenden Faches: Geologie. Der Entscheidungsprozess ging zeitlich einher mit der weltanschaulichen Gedankenentwicklung der Pubertätsjahre, die mich zum Anhänger der zionistischen Idee machte. Beide Gesichtspunkte entschieden 1924 meine Einwanderung ins damals britische Mandatsland Palästina, um beim Aufbau der zionistischen Siedlungen sowie ein Jahr später auch an der Hebräischen Universität mitzuwirken. Es galt also, die Universitätslaufbahn einzuschlagen und diese mit der geologischen Exploration des Landes Israel zu verbinden.Nach Schilderung der Jugend, der Studentenzeit und der Einwanderung ins Heilige Land folgt die Beschreibung der Lehr- und Forschungstätigkeit. Zu Beginn meiner Universitätstätigkeit anno 1925 gab es für geologische Forschung und Lehre keinerlei Lehrmaterial, keine Bibliothek, keine topographischen Karten, bis Mitte der dreißiger Jahre fehlte ein motorisiertes Fahrzeug für die Feldforschung.Der chronische Geldmangel der Hebräischen Universität sowie ihr zunächst nicht besonders großes Interesse an der Einführung des Faches Geologie konnten mich nicht abhalten, durch persönliches Schnorren halbangestellte Laboranten zur Weiterbildung ins Ausland zu schicken, Erforschtes zu publizieren, mit Vorträgen an Kongressen teilzunehmen und mich in der Praxis vor allem der Grundwasser- und in späteren Jahren auch der Erdölexploration und anderen Aufträgen in der angewandten Geologie zu widmen. Das noch recht bescheidene Laboratory of Geology entwickelte sich erst in den folgenden beiden Dekaden zu einem wirklichen Institute of Geology.Mit der Gründung des Staates Israel 1948 kamen dann staatliche Aufgaben hinzu: die Schaffung des "Geological Survey", geologische Kartierung, Überwachung der Erdölkonzessionen und außer der Forschung des Grund- und Quellwassers auch die der Oberflächengewässer zwecks Errichtung des Tiberias-Jordan-Negev-Wasserkanalsystems. Das waren Arbeiten, die endlich jungen Geologie-Absolventen erstmals die Chance eines eigenen Einkommens in ihrem Fach verschafften.Die Evolution der geologischen Wissenschaft und ihre Anwendung gleicht somit in vieler Hinsicht der landwirtschaftlichen wie auch dem zunehmenden industriellen Aufbau des Landes und verdient zu Recht gleicherweise als "pioneering" angesehen zu werden....

Friedrich Gottlob Hayne wurde am 18. März 1763 in Jüterbog geboren und ist am 28. April 1832 in Berlin gestorben. Er war ein deutscher Botaniker, Apotheker und Hochschullehrer. Sein offizielles botanisches Autorenkürzel lautet "Hayne".Das Werk "Getreue Darstellung und Beschreibung der in der Arzneykunde gebräuchlichen Gewächse" umfasst 13 Bände mit 2.596 Seiten und 624 Kupfertafeln und ist in der Zeit von 1805 bis 1837 erschienen. Dieses Werk ist die Grundlage diese Buches.Ich gebe zu, ich bin ein großer Freund von alten Illustrationen. Die Illustrationen von Pflanzen und Tieren, zu denen auch die Insekten zählen, sind sehr detailreich. Diese Illustrationen wurden mit hohem Aufwand hergestellt und man kann sie mit gutem Gewissen als künstlerische Werke bezeichnen!Alle Illustrationen waren anfangs handkolorierte Kupferstiche, die die Texte komplettieren sollten. Die Identifikation der Pflanzen wurde durch diese exakten morphologischen Detailzeichnungen vervollständigt. Dazu war natürlich eine enge Zusammenarbeit von Botaniker und Illustrator von großer Wichtigkeit.Mit der Wiedergabe der Illustrationen in diesem Buch, möchte ich die Arbeit der Illustratoren würdigen.
