Scope of the study The degradation of renewable natural resources in the arid areas of South West Asia has become a matter of great concern. Locally the effects of careless utili zation of the land and its resources had been felt long ago. It is, however, only relatively recently that the gravity of the situation is being generally and fully realised. It is now well understood that action is required to save what is left and possibly to restore what was once there. Such action requires organization and coordination, but above all knowledge of the present state of the resources and the impact of utilization processes. Part of this knowledge is already available.

Download or read book The Biology and Utilization of Shrubs written by Cyrus McKell and published by Elsevier. This book was released on 2012-12-02 with total page 677 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Biology and Utilization of Shrubs brings together the wide range of information about shrubs from many disciplines and world locations. The book is organized into seven parts. Part I describes the major shrublands found on each of the vegetated continents. It provides an overview of the dominant shrubland types as well as the associated features of soil and climate that influence the geographic distribution of major shrub species. Part II discusses environmental influences and plant responses. Part III considers the range of genetic diversity for important traits and how these may vary in different habitats. Part IV discusses the effects of stress on physiological processes of shrubs, and the kinds of strategies shrubs employ to meet physiological stress. Part V offers evidence to support the claim that the many virtues of shrubs provide a basis for sustaining shrub use for livestock fodder, wildlife habitat, reclamation and erosion control, fuel, and naturalized landscaping. Part VI outlines methods for collecting and processing seeds from natural stands or from superior genotypes planted in seed production orchards. Part VII describes cultural adaptation to shrub use in a livestock-dominated primitive culture, followed by a detailed economic analysis of establishing shrub plantations to improve livestock production.

This book was released on 2009-04-07 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: and used in munitions. Rather the requirements for the agent’s military effects took precedence. In addition, the interaction among the political, technical, and legal challenges connected with the known or possible risks posed by CW agents is complex and sometimes not well understood. This is usually because technical considerations, when acted on, are almost invariably informed by political ones, such as various legal requirements. The book contains nine chapters covering different aspects of the research on environmental consequences of war and its aftermath and covers in one additional chapter more general issues such as prevention of war and its environmental c- sequences, the legal, political, and technical background to selected environmental and human health effects of CW agents, and the atmospheric transport and depo- tion of persistent organic pollutants under warfare conditions to more specific ones related to two main tragic examples: the war in the Balkans and the Gulf War. Aspects of the war in the Balkans cover contamination by heavy metals in Serbian national parks, the impact of NATO strikes on the Danube river basin, and the problems associated with transuranium elements. The Gulf War in Kuwait covers other problems related to the impact of oil contamination, the impact on grou- water resources, and the soil damage of ground fortifications among other envir- mental and health problems.

Download or read book Handbook of Plant Palaeoecology written by R. T. J. Cappers and published by Barkhuis. This book was released on 2012-07-03 with total page 477 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant palaeoecologists use data from plant fossils and plant subfossils to reconstruct ecosystems of the past. This book deals with the study of subfossil plant material retrieved from archaeological excavations and cores dated to the Late Glacial and Holocene. One of the main objectives of this book is to describe the processes that underlie the formation of the archaeobotanical archive and the ultimate composition of the archaeobotanical records, being the data that are sampled and identified from this immense archive. Our understanding of these processes benefits from a knowledge of plant ecology and traditional agricultural practices and food processing. This handbook summarizes the basic ecological principles that relate to the reconstruction of former vegetations and of agricultural practices in particular. We hope this book will help palaeobotanists, environmental archaeologists, and colleagues from related disciplines optimize inferences based on what we could term old-style archaeobotany. And we hope that our observations will serve as an eye-opener and improve future research, not only as it is practised in our laboratories, but also as it is practised in the field.
Download or read book Vegetation Ecology of Socotra written by Gary Brown and published by Springer Science & Business Media. This book was released on 2012-05-22 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the unique flora of the Socotra Archipelago with its high degree of endemism has received much attention recently, little information is available on the vegetation and related ecological aspects. Based on their extensive field experience of the region, the authors have assimilated a vast amount of knowledge to produce this book, which gives a detailed insight into the plant ecology of Socotra, designated as a World Heritage Site by UNESCO in 2008. The book is divided into seven chapters. After a brief introduction and overviews of important abiotic features, various aspects of the vascular flora are presented in Chapter 4, together with accounts of the bryophyte and lichen flora. Ecology and adaptive strategies of the plants are dealt with in Chapter 5, and Chapter 6 gives a concise description of the main vegetation units. Finally, important management issues of the vegetation are discussed, an essential topic to ensure preservation of the natural heritage of the archipelago.

Download or read book Woody Plants in Agro Ecosystems of Semi Arid Regions written by Henk Breman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a quantitative analysis of the role of woody plants in semi-arid regions, for the aSSessment of their benefits in agrosylvopastoralland-use systems with productive and sus tainability objectives. The insights presented and conclusions drawn allow the additional benefits of woody plants for specific climatic and physical site conditions and land-use systems to be estimated. The Sahel and Sudan zones in West Africa, on which the book focusses, represent resource-poor conditions, whose ecological dynamics have been relatively well studied. The role of woody plants in this region, as assessed in this book, is extrapolated to other semi-arid regions, leading to general conclusions on agroforestry's potential as an option for sustainable land use in semi-arid regions. The origins of this book go back to 1982, when the Club du Sahel requested that available data on woody plants in the Sahel region be synthesised, to provide basic information to enable better attention to be given to woody plants in rural development programmes. We are grateful to the Club du Sahel for this challenge. Various people contributed to studies used in this book. The preliminary inventory of the data available was made by Frits Ohler; later his work was continued by Franciska Dekker.
Download or read book Euphrates and Tigris Mesopotamian Ecology and Destiny written by J. Rzóska and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scope and limitations of this book I am trying here to present the natural history of a land largely created and dominated by two great rivers, the Euphrates and Tigris. All rivers have two main functions, quite different from lakes; they transport water and eroded material sometimes over large distances. The astute Greeks, who penetrated here in the 4th century B.C., called the land Mesopotamia, an apt name; it is the only region in the Near East, except Egypt, having the benefit of large rivers. Another name coined in antiquity was 'Fertile Crescent', stretching from Egypt to present day Iraq; Herodotus marvelled at the fertility of the soils, the abundance of water and the magnificent cities of Mesopotamia. Thus a further role of some great rivers is recognized as foci of human development. The desire to collate this book arose from a similar motif as in the Nile book (1976), the intricate connection between man and rivers.
Download or read book Rivers of the Sultan written by Faisal H. Husain and published by Oxford University Press. This book was released on 2021-03-05 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Tigris and Euphrates rivers run through the heart of the Middle East and merge in the area of Mesopotamia known as the "cradle of civilization." In their long and volatile political history, the sixteenth century ushered in a rare era of stability and integration. A series of military campaigns between the Mediterranean Sea and the Persian Gulf brought the entirety of their flow under the institutional control of the Ottoman Empire, then at the peak of its power and wealth. Rivers of the Sultan tells the history of the Tigris and Euphrates during the early modern period. Under the leadership of Sultan Süleyman I, the rivers became Ottoman from mountain to ocean, managed by a political elite that pledged allegiance to a single household, professed a common religion, spoke a lingua franca, and received orders from a central administration based in Istanbul. Faisal Husain details how Ottoman unification institutionalized cooperation among the rivers' dominant users and improved the exploitation of their waters for navigation and food production. Istanbul harnessed the energy and resources of the rivers for its security and economic needs through a complex network of forts, canals, bridges, and shipyards. Above all, the imperial approach to river management rebalanced the natural resource disparity within the Tigris-Euphrates basin. Istanbul regularly organized shipments of grain, metal, and timber from upstream areas of surplus in Anatolia to downstream areas of need in Iraq. Through this policy of natural resource redistribution, the Ottoman Empire strengthened its presence in the eastern borderland region with the Safavid Empire and fended off challenges to its authority. Placing these world historic bodies of water at its center, Rivers of the Sultan reveals intimate bonds between state and society, metropole and periphery, and nature and culture in the early modern world.

Download or read book Halophyte Plant Diversity and Public Health written by Münir Öztürk and published by Springer Nature. This book was released on 2023-03-01 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: Salinity is one of the acute problems causing enormous yield loss in many regions of the world. This phenomenon is particularly pronounced in arid and semiarid regions. Halophytes can remove salt from various types of problematic soils due to their unique morphological, physiological and anatomical adaptations to these environments. Halophytes are also used for the treatment of certain diseases but scientific documentation in terms of current phytotherapic applications is deficient in this unique group of plants. Different ethnic groups around the world use medicinal halophytes according to their own beliefs and ancestor’s experiences. However, their knowledge about the use of salt tolerant medicinal plants is usually confined to their own community. There is thus a knowledge gap on halophytes which should be bridged and preserved. This book provides a comprehensive account on the distribution of halophytes, their ethnobotanical and medicinal aspects, economic importance, and chemical constituents along with scientific description. The book therefore serves as a valuable resource for professionals and researchers working in the fields of plant stress biology and ethnobotanical aspects.
