Download or read book Plant Responses to Hyperarid Desert Environments written by Monier M. Abd El-Ghani and published by Springer. This book was released on 2017-11-10 with total page 601 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive discussion on plant responses in hyperarid regions of Egypt, China, Mexico, and Pakistan. It describes their location, physiographic features, accidental vegetation along two transects, endangered vegetation species, human impact, and variety of plant types (e.g. climbing, succulent, and parasitic). Studies on biotic and abiotic interactions, plant biodiversity, and soil-plant relationships are also covered. Covering a wide range of plant conditions and adaptations, this book analyzes what happens when plants must endure very high temperatures and aridity. Plants have adapted by evolving their physical structure to store and conserve water. Examples are the absence of leaves which reduces transpiration and the growth of extremely long roots, allowing them to acquire moisture at, or near the water table. Plants in hyperarid habitats have also made behavioral adaptations in order to survive by synchronizing with the seasons of greatest moisture and/or coolest temperatures. For example, desert perennials remain dormant during dry periods of the year, then spring to life when water becomes available. The book includes many color illustrations, and has extensive and up-to-date references for further reading.

Download or read book The Exploitation of Plant Resources in Ancient Africa written by Marijke van der Veen and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents a completely new and very substantial body of information about the origin of agriculture and plant use in Africa. All the evidence is very recent and for the first time all this archaeobotanical evidence is brought together in one volume (at present the information is unpublished or published in many disparate journals, confer ence reports, monographs, site reports, etc. ). Early publications concerned with the origins of African plant domestication relied almost exclusively on inferences made from the modem distribution of the wild progenitors of African cultivars; there existed virtually no archaeobotanical data at that time. Even as recently as the early 1990s direct evidence for the transition to farming and the relative roles of indigenous versus Near Eastern crops was lacking for most of Africa. This volume changes that and presents a wide range of ex citing new evidence, including case studies from Nigeria, Burkina Faso, Ethiopia, Uganda, Egypt, and Sudan, which range in date from 8000 BP to the present day. The volume ad dresses topics such as the role of wild plant resources in hunter-gatherer and farming com munities, the origins of agriculture, the agricultural foundation of complex societies, long-distance trade, the exchange of foods and crops, and the human impact on local vege tation-all key issues of current research in archaeology, anthropology, agronomy, ecol ogy, and economic history.

Available in PDF, EPUB and Kindle. Book excerpt: This book is an attempt to compile and integrate the information documented by many botanists, both Egyptians and others, about the vegetation of Egypt. The ? rst treatise on the ? ora of Egypt, by Petrus Forsskal, was published in 1775. Records of the Egyptian ? ora made during the Napoleonic expedition to Egypt (1778–1801) were provided by A. R. Delile from 1809 to 1812 (Kassas, 1981). The early beginning of ecological studies of the vegetation of Egypt extended to the mid-nineteenth century. Two traditions may be recognized. The ? rst was general exploration and survey, for which one name is symbolic: Georges-Auguste Schweinfurth (1836–1925), a German scientist and explorer who lived in Egypt from 1863 to 1914. The second tradition was ecophysiological to explain the plant life in the dry desert. The work of G. Volkens (1887) remains a classic on xeroph- ism. These two traditions were maintained and expanded in further phases of e- logical development associated with the establishment of the Egyptian University in 1925 (now the University of Cairo). The ? rst professor of botany was the Swedish Gunnar Tackholm (1925–1929). He died young, and his wife Vivi Tackholm devoted her life to studying the ? ora of Egypt and gave leadership and inspiration to plant taxonomists and plant ecologists in Egypt for some 50 years. She died in 1978. The second professor of botany in Egypt was F. W.

Book excerpt: Egypt has one of the oldest and most productive agricultural systems in world, yet it has become one of the world's largest food importers. Today, as the Egyptian government undertakes a major agricultural reform program, the lessons of its past practices and current development need to be shared with the rest of the world. This text--written by Egyptian agricultural experts and other specialists--provides a comprehensive introduction and reference to Egypt's agricultural practices from their earliest origins through the 1990s. Topics range from the country's environmental history, to shifting population dynamics, to changing governmental and economic structures. Detailed descriptions of agricultural production and development in the northern Littoral region, the Delta, middle and upper Egypt, and the deserts are also provided. Written for agronomists, historians of the Middle East, and students and policy makers specializing in third-world development and agricultural systems, this work is an indispensable guide to the region's agricultural history and conventions.

This book was released on 2021-05-31 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews the economic potential of various natural resources found in the Egyptian deserts that could help fill the food gap in Egypt, e.g., the date palm, olives, and domestic animals. Bearing in mind that the entire country is subject to arid or hyperarid climatic conditions, only a small portion (3% of total area) is agriculturally productive in comparison, the dominant deserts. These aspects, combined with a growing population (ca. 100 million citizens) and water resources scarcity, have produced severe adverse effects on natural resource utilization. This book presents innovative methods for addressing desert soil's key problems (soil erosion, salinity, pollution, decreased fertility, minerals, and weed and pest control). Its goal is to help authorities reclaim the desert and optimally utilize the minerals and the available natural resources to support the sustainability agenda 2030. Besides, it offers researchers guidance on remaining gaps and future research directions. Lastly and importantly, it provides essential information on investment opportunities in desert cultivation, such as the fields of food, fodder, and medicinal plants.

Available in PDF, EPUB and Kindle. Book excerpt: There is an essential connection between humans and plants, cultures and environments, and this is especially evident looking at the long history of the African continent. This book, comprising current research in archaeobotany on Africa, elucidates human adaptation and innovation with respect to the exploitation of plant resources. In the long-term perspective climatic changes of the environment as well as human impact have posed constant challenges to the interaction between peoples and the plants growing in different countries and latitudes. This book provides an insight into/overview of the manifold routes people have taken in various parts Africa in order to make a decent living from the provisions of their environment by bringing together the analyses of macroscopic and microscopic plant remains with ethnographic, botanical, geographical and linguistic research. The numerous chapters cover almost all the continent countries, and were prepared by most of the scholars who study African archaeobotany, i.e. the complex and composite history of plant uses and environmental transformations during the Holocene.
