Understanding Water in a Dry Environment

Understanding Water in a Dry Environment PDF Author: Ian Simmers
Publisher: CRC Press
ISBN: 9789058096180
Category : Science
Languages : en
Pages : 370

Book Description
In order to provide water security in the twenty-first century, there is universal agreement that a continuation of current policies and extrapolation of trends is not an option. Also clear is that from both water supply and development perspectives, the world's arid and semi-arid regions are those currently and potentially experiencing the highest water stresses. One third of the world's land surface is classified as arid or semi-arid, and about half of all countries are directly affected in some way by problems of aridity. The hydrology of arid and semi-arid areas is also known to be substantially different from that in more humid regions. It is therefore essential that investigation methods appropriate to the former are developed and applied, and that strategies for arid and semi-arid region water resources development recognise the principal characteristics of in-situ hydrological processes.

Vegetation, Water, Humans and the Climate

Vegetation, Water, Humans and the Climate PDF Author: P. Kabat
Publisher: Springer Science & Business Media
ISBN: 9783540424000
Category : Gardening
Languages : en
Pages : 598

Book Description
This book presents a state-of-the-art scientific overview of the influence of terrestrial vegetation and soils within the Earth system. It deals especially with interactions between the terrestrial biosphere and the atmosphere via the hydrological cycle and their interlinkage with anthropogenic activities. Measurements gathered in integrated field experiments in the Sahel, the Amazon, North America and South-east Asia confirm the importance of these interactions, but a substantial data consolidation effort still needs to be undertaken. Observations are complemented by modelling studies, including regional models that simulate flows and transport in river catchments, coupled land-cover and regional climate systems, and Earth-system and global circulation models. Water, nutrient and sediment fluxes in river basins are also discussed and are shown to be highly impacted and regulated by humans through land use, pollution and river engineering. Finally, the book discusses environmental vulnerability and methodologies for assessing the risks associated with regional and global climatic and environmental variability and change.The editors emphasise that the results reported in this book are based on the research work of many individual scientists and teams around the world associated with the objectives of the IGBP-BAHC and WCRP-GEWEX international research programmes.

Tamarix

Tamarix PDF Author: Martin F. Quigley
Publisher: Oxford University Press
ISBN: 0199898219
Category : Science
Languages : en
Pages : 513

Book Description
The invasive species Tamarix first attracted the public eye in the 1990's when it was suspected of contributing to widespread drought and wildfires in the Western United States. Once purported to consume as much water as entire cities, very few plant species have received as much scientific, public, and political discussion and debate as Tamarix. Written by 44 of the field's most prominent scholars and scientists, this volume compiles 25 essays on this fascinating species--its biology, ecology, politics, management, and the ethical issues involved with designating a particular species as "good" or "bad". The book analyzes the controversy surrounding the Tamarisk's role in our ecosystems and what should be done about it.

Environmental Physiology of Plants

Environmental Physiology of Plants PDF Author: Alastair H. Fitter
Publisher: Academic Press
ISBN: 0080549810
Category : Science
Languages : en
Pages : 396

Book Description
This is the third edition of an established and successful university textbook. The original structure and philosophy of the book continue in this new edition, providing a genuine synthesis of modern ecological and physiological thinking, while entirely updating the detailed content. New features include a fresh, unified treatment of toxicity, emphasizing common features of plant response to ionic, gaseous, and other toxins, explicit treatment of issues relating to global change, and a section on the role of fire in plant physiology and communities. The illustrations in the text are improved over previous editions, including color plates for the first time, and the authors' continuing commitment to providing wide citation of the relevant literature has further improved the reference list. This revision of Environmental Physiology of Plants will ensure the reputation of this title as a useful and relevant text well into the 21st century. - Includes enhanced illustrations, now with color plates - Examines new molecular approaches which can be harnessed to solve problems in physiology - Features new topics such as the unified treatment of toxicity, an explicit treatment of the issues relating to global change, and a section on the role of fire

Global Livestock Production Systems

Global Livestock Production Systems PDF Author: Timothy P. Robinson
Publisher: Food & Agriculture Organization of the UN (FAO)
ISBN: 9789251070338
Category : Animal Production
Languages : en
Pages : 0

Book Description
Informed livestock sector policy development and priority setting is heavily dependent on a good understanding of livestock production systems. In a collaborative effort between the Food and Agriculture Organization and the International Livestock Research Institute, stock has been taken of where we have come from in agricultural systems classification and mapping; the current state of the art; and the directions in which research and data collection efforts need to take in the future. The book also addresses issues relating to the intensity and scale of production, moving from what is done to how it is done. The intensification of production is an area of particular importance, for it is in the intensive systems that changes are occurring most rapidly and where most information is needed on the implications that intensification of production may have for livelihoods, poverty alleviation, animal diseases, public health and environmental outcomes. A series of case studies is provided, linking livestock production systems to rural livelihoods and poverty and examples of the application of livestock production system maps are drawn from livestock production, now and in the future; livestock's impact on the global environment; animal and public health; and livestock and livelihoods. This book provides a formal reference to Version 5 of the global livestock production systems map, and to revised estimates of the numbers of rural poor livestock keepers, by country and livestock production system.
