Despite international initiatives such as the Earth Summit in 1992 and ongoing efforts to implement the Kyoto Protocol, human activities continue to register a destructive toll on the planetary environment. At root, research on global environmental risk seeks new pathways for reversing unsustainable trends, curtailing ongoing destructive activities, and creating a life-sustaining planet. This book takes stock of the distinctive challenges posed by global environmental risks, the capacity of knowledge systems to identify and characterize such risks, and the competence of human society to manage the unprecedented complexity. Particular attention trains on engaging, in ways conducive to enhancing social learning and adaptation, the large uncertainties inherent in these risks. Various chapters enlist different scales of analysis to explore the manifestation and causes of global environmental risks in all the diversity of their regional expression. Throughout, the editors and contributors accord prominence to the vulnerability of people and places to environmental degradation. Understanding vulnerability is a neglected key to assessing the nature of the risks and determining strategies for altering trajectories of threat. Global risk futures, the editors argue, are not intractable, and are still amenable to a risk-analysis enterprise that is democratic in principle, humanistic in concept, and geared to the realities that pertain to the particular societies, locales, and regions that will ultimately bear the risk.

The ecology of halophytes has a wide scope of interest, appealing to people of many disciplines. It covers widely different fields such as climatology, soil science, phytogeography, adaptive biology and agriculture. Ecologists study these specialized plants in relation to estuarine ecosystems, biology of dominant genera, germination ecology, water relations, salt secretion, and senescence. The present volume is divided into three parts and attempts to elucidate new aspects of the problems faced by this special group of plants. It tries to give the reader an overall view of saline environments and the ecology of plants found therein. In the first chapter of part one Zahran presents the halophytic vegetation of Egypt, which includes the inland and the littoral (Red Sea and Mediterranean Sea) salt marshes. The plants he describes have been classified as succulents, excretives and cumulatives, according to their adaptability to saline soils and according to their different life-forms. The second chapter throws light on the estuarine ecosystem ofIndia. The estuaries are described by Joshi, and Bhosale as being rich in diversity of mangrove species. Making varied use of estuarine ecosystems is not only possible, but also essential because they are the meeting point between terrestrial and marine life.
