Increase in world population, extreme weather conditions, decrease in fresh water supplies, and changes of dietary habits are major issues that affect global food security. We are expected to face the challenges of land use by 2050 because population will reach 9 billion while agricultural productivity losses are expected due to overuse of lands. How can we feed the next generations in a manner that respects our finite natural resources? Managing our resources in a sustainable way have only begun for selected crops. Much remains to be done to increase food yield. Cropping practices capable of sustainable production need to be elaborated, especially in fragile ecosystems. Typical applications...
This book is the sixth and final volume in the Tasks for Vegetation Science book series, and it concludes the most comprehensive scientific documentation dealing with hypersaline ecosystems of the world.
This volume focuses on reclamation, management, and utilization of salt-affected soils, their sustainable use, and evaluation of plants inhabiting naturally occurring saline habitats. It is of interest to scientists and students as well as agricultural institutions and farmers to increase the awareness of salinity problems. The volume is supported by UNESCO Doha, Qatar, and has an international authorship.
Contains 31 contributions presenting the results of recent decades' research on the extensive intertidal and inland saline flats of the Arabian Gulf Region, known colloquially as sabkhat. Only relatively recently acknowledged to be valuable ecosystems with research, development, and conservation value, sabkhat are thoroughly explored in this volume by biologists, geologists, archaeologists, ecologists, botanists, zoologists, and other researchers and scientists from many countries. The volume's 31 contributions are organized into three sections: distribution of sabkhat within the Arabian Peninsula and the adjacent countries (13); sabkha ecology (14); and sabkha land use and development (4). The book includes some fairly low-key b & w photographs, charts, and maps. Annotation copyrighted by Book News, Inc., Portland, OR.
Regions of the world with greatest biodiversity are shown to exhibit greatest linguistic diversity, strongly suggesting that the relationship between language and ecology is both symbiotic and spatially and temporally determined. This volume examines the expressions of, and threats and challenges to, this relationship in southern and eastern Arabia. Exploring the ways in which indigenous languages reflect the close relationship between people and their natural environment, this book presents an overview of the key threats and challenges, and introduces the methodologies used to investigate them. Across the chapters, case studies are presented dealing with language, gesture and ecology, the significance of naming, the role of narratives in the language–ecology relationship, and conservation and revitalisation of bio-cultural diversity in Arabia. Taking a multidisciplinary view, this book argues for the central role that language plays in facing the challenges and threats to bio-cultural diversity, and presents methods for the study of the language–nature relationship that can be applied globally.
Sustainable development is the key for the survival in 21st century. The natural resources are finite and cannot be used with impunity because we are the custodian of these resources and have responsibility to pass these to the next generation. This monumental task requires several major commitments and most important of them is to arrest population explosion which has already reached seven billion. Natural resources like air to breath, food to eat, and water to drink, and fossil fuel to maintain this life style are being overexploited. Unrestrained consuming culture will accelerate undesired situation. This situation will have more dire consequences in resource limited ecosystems like dry l...
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 toleran...
"Despite global progress in understanding the epidemiology of the human immunodeficiency virus (HIV), knowledge about the epidemic in the Middle East and North Africa (MENA) remains limited and subject to much controversy. In the more than 25 years since the discovery of HIV, no scientific study has provided a comprehensive, data-driven synthesis of the spread of HIV/AIDS (acquired immunodeficiency syndrome) in the region. Consequently, the effectiveness of policies, programs, and resources intended to address the spread of HIV/AIDS has been compromised. This report aims to fill the knowledge gap by providing the first-ever comprehensive scientific assessment and data-driven epidemiological ...
The book provides significant information on some of the promising edible medicinal plants and how these possess both nutritive as well as medicinal value. The significance of these edible plants in traditional medicine, their distribution in different regions and the importance of their chemical constituents are discussed systematically concerning the role of these plants in ethnomedicine in different regions of the world. The current volume focuses on the economic and culturally important medicinal uses of edible plants and a detailed survey of the literature on scientific researches of pharmacognostical characteristics, traditional uses, scientific validation, and phytochemical composition, and pharmacological activities. This book is a single-source scientific reference to explore the specific factors that contribute to these potential health benefits, as well as discussing how to maximize those potential benefits. Chemists, food technologists, pharmacologists, phytochemists as well as all professionals involved with quality control and standardization will find in this book a valuable and updated basis for their work.
This book is part of the Sabkha Ecosystems series. The series is designed to provide information on sabkha ecosystems of different regions. It will add to the collective knowledge available about saline ecosystems and also focuses on the African region where only limited information is currently available on.
