Virtual Water
The groundbreaking new concept that reveals the true and hazardous extent of our everyday water consumption. How much water does it take to make a cup of coffee? The answer may shock you: 140 litres! That's the true amount of water used in growing, producing, packaging and shipping the beans you use to make your morning coffee. Your lunchtime hamburger takes 2,400 litres and that favourite pair of blue jeans a whopping 11,000 litres. In fact, all the goods we buy - from food to clothing to computers - have a water cost in the form of virtual water: the powerful new concept that reveals the hidden facts of our real water consumption. At a time when the world's resources are being used up at increasingly alarming rates what can we do to help tackle the threat to our planet's most precious resource? World water expert Tony Allan - creator of the virtual water concept - shows the way. In this stimulating and enjoyable book he exposes the real impact of our modern lifestyle and shows how we as individuals, and governments globally, can make a vital contribution to managing our water use in a more sustainable and planet-friendly way.
Water Intake, Body Water Regulation and Health
The purpose of this Special Issue, “Water Intake, Body Water Regulation, and Health”, is to present novel reviews and experimental data regarding hydration physiology and its implication in overall health. Water has previously been dubbed the forgotten nutrient due to humans’ and animals’ ability to subsist seemingly unchanged across a wide range of daily water intakes. However, with the introduction of stressors such as exercise, diseased states, and/or chronic high or low water intake, the homeostatic signals related to body water regulation can influence organ and whole-body health. This Special Issue will discuss water intake, the scientific rationale surrounding the U.S. and European water intake guidelines, homeostatic mechanisms, diseases related to dysfunction of water regulation, and differences in the volume and the vehicle in which the water is contained (i.e., plain water versus mixed beverages) on water intake during and following exercise. The aim is to continue discussion surrounding water, the previously forgotten nutrient, and highlight the importance of water in daily life.
Water Consumption and Scarcity
People are only able to use about 1 percent of Earth's water. More than 1 billion people do not have access to clean water. Learn more in Water Consumption and Scarcity.
Water Consumption and Factors Influencing Hydration Status
Objectives. This study aimed to provide data on water intake from food and beverages of free-living adults in their natural environment, and investigate how this is affected by physiological, psychological, social and environmental factors. A further aim was to monitor the hydration status of free-living adults and relate this data to water intake. Methods The consumption of all food and beverages was recorded in a diary over three consecutive days by 80 healthy adults (40 males, 40 females), aged 18 to 65 years, who were instructed to continue their normal eating and drinking habits and lifestyles throughout the study. The data was analysed to determine total daily water intake and how this...
The Water Footprint of Modern Consumer Society
Water is not only used in the domestic context, but also in agriculture and industry in the production of commercial goods, from food to paper. The water footprint is an indicator of freshwater use that looks at both direct and indirect use of water by a consumer or producer. The water footprint of an individual, community or business is defined as the total volume of freshwater that is used to produce the goods and services consumed by the individual or community or produced by the business. This book shows how the water footprint concept can be used to quantify and map the water use behind consumption and how it can guide reduction of water use to a sustainable level. With a number of case...
World Water Demand and Supply, 1990 to 2025
Presents two alternative scenarios of water demand and supply for 118 countries over the 1990 to 2025 period and develops indicators of water scarcity for each country and for the world as a whole. This study is the first step in IWMI’s long-term research goal: to determine the extent and depth of water scarcity, its consequences for individual countries and what can be done about it.
Total Water and Tapwater Intake in the United States
Presents estimates of total water and tap water intake in the population of the continental United States, based on data collected during the 1977-78 Nationwide Food Consumption Survey of the U.S. Department of Agriculture. Describes in detail the methods used to derive the estimates. Data are presented by age group, sex, season and geographic region, and separately for pregnant women, lactating women, and breast-fed children.
