Water is an essential recurring input for agriculture productivity and key to food security. Its availability in space and time has been a matter of great concern in many parts of the world. In India there is growing awareness about the scarcity of water under the increased water demand from agriculture and other sectors. Further, the projected reduction in water availability to the agriculture sector from the share of 89

Summaries (En) | What will happen to food production and global food security as water becomes increasingly scarce? What steps can we take to avert threats to global food supply, the environment and the livelihoods of those lacking access to clean water? Using state-of-the-art computer modelling to show how water availability and demand are likely to evolve, the book contends that if current water policies continue, so will high levels of food insecurity, environmental degradation, and water-related ill health. Further neglect of water issues could produce genuine water crisis, which in turn could lead to a food crisis. The authors show exactly which policies and actions could ensure sustainable and efficient water use, enough food for the world's people, and adequate drinking water for all. | Gift

Are we headed toward a worldwide water crisis? The increasing demand for water among households, industry, the environment, and especially agriculture is making global water scarcity a perilous possibility.What will happen to food production and global food security as water becomes increasingly scarce? What steps can we take to avert threats to global food supply, the environment, and the livelihoods of those lacking access to clean water? Using state-of-the-art computer modeling to show how water availability and demand are likely to evolve, World Water and Food to 2025 contends that if current water policies continue, so will high levels of food insecurity, environmental degradation, and water-related ill health. Further neglect of water issues could produce a genuine water crisis, which in turn could lead to a food crisis. But we can avoid these outcomes if we make fundamental policy changes now.The authors show exactly which policies and actions could ensure sustainable and efficient water use, enough food for the world’s people, and adequate drinking water for all."-- "About This Book

Reuse of water in the food industry is attracting much attention due to the increasing cost of water and water discharge. A major obstacle for extensive reuse is the associated risk of microbiological contamination of food and the production environment. A hazard analysis critical control point based generic model has, therefore, been elaborated for implementation and evaluation of systems for the reuse of water in the food industry. The model includes information on food and water borne pathogens and their sensitivity towards various water treatment methods. Previous implementation of the pre-requisite programs and combination of knowledge from very different research areas are also required for safe implementation of water reuse in the food industry.

Current use of ion exchange unit process in water treatment for food industry is mainly for boiler feed water softening. However, potentials of ion exchange in water treatment process are of greater significance, which is exactly the matter researched in this paper. After a short review of ion exchange unit process basics, and ion exchangers as an equipment (in scope of that, a suggestions for investitor about techno-econommic analysis of offered solutions for ion exchanger line design is given, in order to minimize errors in plan and design, which might be harmful for investitor), options of using ion exchange in some phases of water treatment process for food industry are discussed, like removing of: mineral matter (softening, decarbonization, demineralization), natural organic matter, and some other constituents (nitrate, ammonia, heavy metals).
