Multiple use of water- the need of the hour

Water is one of the most precious natural resources after soil and these two resources provide the foundation for food, nutritional and livelihood security. The declining per capita water availability coupled with degrading land and water resources pose serious challenge to humanity and underscore the need for protection and efficient management. Multiple use of water is one option which has the potential to meet future demand for increasing productivity in the long term.

From agricultural point of view, multiple uses of water may be made in various production systems e.g. crops, horticulture, forests, fishery, livestock, poultry, duckery, small scale industries, domestic are prominent water users of agriculture. These production system needs to utilize same water resource in an efficient way. It is a challenging task to improve the water productivity at the field level as well as at system or region level. The major aim of the multiple uses of water is:

* enhancing water productivity
* increasing farm productivity without any additional diversion of water
* enabling diversification to high value outputs
* reducing risk, better use of resources and increased resource use efficiency
* ensuring increased income and better flow of income throughout the year
* enabling better utilization of otherwise wasted/depleted water resources, water congested/waterlogged areas

However, the conventional system of water resource development do not consider the multiple uses while designing the system and hence, putting it in different uses at a later stage will certainly creates several problems such as pollution, wastage, waterlogging, etc. Hence, multiple uses have to be considered right from the planning stage.

+1KS. And, aside from multipel uses, also to look out for opportunities to harvest water for instance when constructing houses, greenhouses etc. can we design them with water harvesting in mind.

We here in Chicago are fond of using "brown water" rainwater runoff, dishwatear, bathwater, etc to irrigate our lawns and backyard gardens. Thanks for reminding about multiuse.

Thanks Pradip - I am just figuring out how to save my "gray water" and use it. We really do waste so much of everything!

Nice Pradip.... I also love this idea of multiple water use. Clean things and re-use that water if it is still safe!

Fourth of July on the Lake

This past weekend was the annual celebration at the lake house in Connecticut. It is amazing that the lake is still so clear and beautiful after all these years. The watershed association has done a wonderful job protecting these waters from the damaging effects of development.The wood grill was finally ready to cook on, so we didn't miss the propane tank fueled grill anymore. The food actually tasted fresher than in the past and was easy to keep fueled.Dad was very proud of the solar hybrid…See More

In this blog post I will focus on a plant that is abundant in our nature, and which is immensely nutritious. It's of course the Stinging Nettle.

In addition the Stinging Nettle consists…See More

Future

FutureToday is 2020/1/1. It is just like yesterday. The war is still continuing. It has started since 2010. In 2010, that year was a horrible year. Almost every energy ran out. Every country’s governments were crushed down at the same time. There were riots everywhere. All of the big company’s bosses were killed xdeadx in the riots. Troops fought each other everywhere. Food was bought up xawayx at once. There were no more food supplies in any shops. The economy was all crushed down. All the…See More

public servants

The exchange works directly for state and public workers and servants. It gives them credit in exchange for the amount of public work they contribute to the community. The more constructive they are based off a base rate the more credit they recieve.
