Product Description
Today the world is facing a greater water crisis than ever. Droughts of lesser magnitude are resulting in greater impact. Even in years with normal precipitation, water shortages have become widespread in both developing and developed nations, in humid as well as arid climates. When faced with severe drought, governments become eager to act. Unfortunately, this eagerness usually wanes when precipitation returns to normal.

Drought and Water Crises: Science, Technology, and Management Issues explains the complexities of drought and the role of science, technology, and management in resolving many of the issues associated with the world's expanding water crises.

Contributors discuss a broad range of topics in attempting to answer these most pressing questions:

How can we can improve planning tools and make mitigation tools more readily available and adaptable?

How can we promote widespread adoption of new water-conserving technologies and encourage their use during non-drought periods?

How can seasonal forecasts and early warning systems be made more reliable and expressed in ways to better meet the needs of end users?

How can the drought-related policy experiences of some countries be systematically utilized to benefit others?

Drought and Water Crises collates considerable information from diverse disciplines with the goal of reducing societal vulnerability to drought. Featuring case studies and stressing new technologies, the book seeks to encourage nations to adopt a more risk-based, proactive policy for water and drought management. ... Read more

From the supplier: The sertao or backland in Brazil's northeastern region is a 900,000 sq.km. expanse of semiarid land which is prone to recurrent extremes of droughts and floods. Water storage has been the main strategy used for dealing with the problem but it is more of a short-term solution with limited effectiveness. Scientists believe that a strategy which emphasizes conservation and the prevention of environmental dessication is the best way to manage the droughts and floods in the region.

Description:
Hill evergreen forest is the dominant vegetation type in northern Thailand. In this region, there is higher atmospheric evaporative demand and lower soil moisture during the 5- to 7-month dry season than in the rainy season under influences from Asian monsoons. In an earlier study we revealed that canopy-scale transpiration is actively maintained even during the latter part of the dry season in hill evergreen forest. However, the impact of soil drought on tree water use was not investigated. To clarify the ecohydrological processes at this site, we used individual tree-scale measurements during a 2-year period to base our examination of whether limited water use in individual trees is caused by soil drought in the latter part of the dry season. Sap flow and water potential measurements were conducted in four evergreen trees, two large emergent trees 29.8 and 25.4m high, and two smaller understory trees 4.8 and 1.4m high. The amount of rainfall preceding the late dry season of 2004 was significantly less than that preceding the late dry season of 2003. Although a distinct decrease in sap-flow velocities in individual trees due to soil water stress was not found in the late dry season of 2003, it did become comparatively apparent in the late dry season of 2004; ranging from 10 to 40% for a given atmospheric evaporative demand. Furthermore, the reductions in sap-flow velocities and predawn stem-water potential were most significant in the smallest tree. The recovery of sap-flow velocities and water potential in the smallest tree after irrigation confirmed that the reductions in sap-flow velocity and predawn stem-water potential in the smallest tree were caused by soil drought. These results suggest that shallower roots could be reason for the significant decrease in water use in the smallest trees. The deeper roots of larger trees could be the reason for the reduced impact of soil drought on water use in larger trees, and canopy-scale transpiration might be maintained by larger trees, even in an unusually severe drought. These possibilities provide a new insight for management of evergreen forests under Asian monsoon influences. ... Read more

I got what I was looking for
Basically, I bought the book looking for a good and detailed classification of polluting agents, which I got.

Good structure, hard to find these days an actual book, all you get is a collection of papers from various authors, so for you, people, looking for a classical book, or even a lecture book, this is a right choice.

I gave just **** because five you get only after the third edition! ;)

Soil, Vadose Zone, and Ground-Water Contamination
I just use this book as a reference on occasion.I really don't like how it is setup or formatted.It does not contain an index which can make it a little difficult if you are trying to specifically find information.I generally go elsewhere if i need information quickly on vadose zone or contamination.I wouldn't recommend purchasing this unless you have had a chance to look at it in person and are sure that it has what you are interested in. ...

Product Description

One of the main problems confronting the world of the 21st Century is a shortage of water. There is already severe scarcity in many regions of the world, causing tremendous problems for local populations and indeed entire societies. There is insufficient water available for the production of food to alleviate poverty and starvation; the lack of water hampers industrial, urban and tourism development, forcing restrictions on other sectors, especially agriculture; health problems arise as the deterioration of ground and surface waters favours water-borne diseases, which flourish in the absence of decent water distribution and sewerage systems. Water conflicts still arise in areas under stress, while water for nature has become a vanishing priority in such zones.

This book is a guide to the establishment of regional and/or local guidelines for developing and implementing new ideas for coping with water scarcity. The basic premise underlying the book is that water scarcity will persist, so personal, human and society-wide skills will be needed to cope with it while living in harmony with the necessary environmental constraints. The book provides basic information to assist decision makers, water managers, engineers, agronomists, social scientists and other professions (and their students) in formulating coherent, hopefully harmonious and consolidated views on the issue. Guidelines are also given for introducing the general public to the concept of water scarcity and how to deal with it.

Description:
Fine roots are the most important plant organs for water and nutrient acquisition. Water and ion uptake is most sensitively altered by the formation of new roots in favourable sites. Fine root turnover, i.e. shedding and replacing fine roots, is therefore important in maximizing root system efficiency. Some evidence exists that accelerating fine root turnover is appropriate to counterbalance negative effects caused by drought albeit formation of new roots in drying soil is a high-risk investment. In the present study, fine root (@?2mm diameter) dynamics in a stand of mature Fagus sylvatica (European beech) was observed during summer 2003 that was extraordinary dry in Central Europe. Depth-related fine root formation and mortality (between 3.4 and 41.6cm soil depth) were observed and related to soil water content and soil temperature. The environmental parameters measured appeared as significant but surprisingly weak determinants for fine root formation and none of them influenced fine root mortality significantly. Fine root mortality was not counterbalanced by root formation but pronounced fine root shedding was found for non-suberized and superficial fine roots. Despite severe soil drying, fine roots were primarily invested in upper and thus unfavourable soil strata. The fine root system of F. sylvatica underlay an almost continuous replacement but there was no evidence for altered fine root turnover as an important response to soil drying. Rather the relative conservative fine root investment pattern and the large losses of fine roots indicate high construction costs at low benefits on the whole plant level and thus may limit the vigour of F. sylvatica if comparable drought periods occur frequently. ...

Description:
The genetic variation in shoot growth, water-use efficiency (as assessed by @d^1^3C) and gum production was compared among eight Acacia senegal provenances originating from contrasting conditions of the gum arabic belt in central Sudan. The experimental site was in the clay plain region. Carbon isotope ratios were obtained from leaves and branch wood samples of the dissimilar A. senegal provenances. The clay provenances were distinctly superior to the sand provenances in all traits studied but especially in basal diameter and crown width, reflecting their adaptation to the environment. Values of @d^1^3C were less negative in the sand group compared to the clay both in leaves and in branch wood. This suggests that sand provenances displayed conservative water use and high drought tolerance. Of the clay provenances, the local one displayed a high negative @d^1^3C value, which indicates less conservative water use that results in high productivity at this particular clay-soil site. Water use appears to correspond to the environmental conditions prevailing at collection sites for these provenances. Results suggest that A. senegal provenances in the clay part of the gum belt are adapted for fast growth rate and high biomass and gum productivity as compared with the provenances from the sand regions: a negative correlation was found between tree gum yield and @d^1^3C. The variation in water use and gum production was greater among provenance groups than within them, suggesting that selection among rather than within provenances would result in distinct genetic gain in gum yield. ...

Description:
Water and nutrients are two of the most important factors controlling the growth of trees. Numerous studies show that fertilization is most effective when trees are not water-stressed and that irrigation is most effective when nutrients are not scarce. The goal of this work was to test the responses of Eucalyptus grandis seedlings to drought as affected by soil type and fertilization with nitrogen (N) or phosphorus (P). Seedlings of E. grandis were planted in pots with two different types of soil: a sandy soil and a clay (black) soil. Plants were fertilized with N or P, and half of them were water-stressed. Fertilization did not affect the growth reduction brought about by drought in the red sands; in the black soil, plants fertilized with P showed a moderate growth increase under drought, compared to non-fertilized plants. Dry mass allocation to roots was decreased by fertilization in water-stressed and well-watered plants in the sandy soil, and in well-watered plants of the black soil, but it increased in water-stressed plants fertilized with N in the black soil. Water use efficiency (WUE), i.e., the grams of water transpired per gram of dry mass accumulated, was not altered by fertilization or water stress in the black soil, although it increased with P fertilization in well-watered plants in the sandy soil. Osmotic adjustment was observed only in plants fertilized with P in the black soil, and in non-fertilized plants in the sandy soil. Osmotic adjustment in water-stressed plants was associated with an increased stomatal conductance. We conclude that water stress tolerance strategies are altered by fertilization depending on soil properties, and that fertilization with P is recommended in black soils even if a moderate drought is likely to occur, but on sandy soils fertilization is recommended only under good water supply. ...

Product Description

Although valuable resources in river basins and other aqueous environments, sediments often receive much less attention from researchers, policymakers, and other professionals than other components of the ecosystem. Until now. Highlighting the important role that sediments play in the geoenvironment, Sediments Contamination and Sustainable Remediation focuses on sediment management for the purpose of environmental cleanup or management. It provides the in-depth understanding of the sediment-water environment needed to develop better management practices and meet sustainability requirements.

The book discusses the contamination of sediments resulting from discharge of pollutants, excessive nutrients, and other hazardous substances from anthropogenic activities. It examines impacts observed as a result of these discharges, including the presence of hazardous materials and eutrophication, and elucidates the remediation techniques developed to restore the health of sediments and how to evaluate the remediation technologies using indicators. The text explores the problems inherent in dealing with contaminated sediments in rivers, lakes, and estuaries and includes numerous case studies that illustrate key concepts.

The authors provide wide-ranging coverage of the topic and include methods for evaluating the effectiveness of different remediation technologies. They make the case for the development and application of innovative management practices that create long-term solutions to sediment contamination to reduce natural resource depletion, continued landfill contamination, and diminished biodiversity in the aquatic geoenvironment.
