Introduction
Water is an essential resource for life on the planet. Although water is the most widespread compound in the world and only three percent of it is freshwater that is suitable for human use. Freshwater is of the upmost importance not only for a stable drinking supply but also for irrigated agriculture, industries, natural ecosystems, rural and urban water supply and sanitation etc.
A very important reason for a growing pressure on limited freshwater resources is the population growth. The population is already over 7 billion people and the minimum requirement for water is 50 liters per person per day. That alone accounts for an enormous amount of freshwater. When we put the populations need for food in the equation we can get a sense of exactly how scarce freshwater will become. For example it takes about 1000 tons of water to grow one ton of grain and 2000 tons of water to grow a single ton of rice. That is why properly managed water resources are a critical component of sustainable growth, poverty reduction and equity.
Water resources management
1 What is WRM
Water resource management is the activity of planning, developing, distributing and managing the optimum use of water resources. Water resource management planning compares all the competing demands for water and seeks to allocate water on an equitable basis to satisfy all uses and demands but that is almost impossible in practice. It is a sub-set of the water cycle
