Question

How is life cycle assessment (LCA) used internationally to address the economic consequences of drinking water supply under climate change?

Answer 1

In the designing of drniking water supply scheme the main point of consideration are mainly the water demand and its cost, and these two are dependent on various factors like -

1. Topography of the area

2. Climatic condition

3. Future growth of the locality

4. Source of water and many other...

And now we know that water supplies around the globe are growing complex and include more intense treatment methods than just decades ago. Now, desalination of seawater and wastewater reuse for both non-potable and potable water supply have become common practice in many places.

LCA studies have been used to support decisions in the planning of urban water systems and some important findings but LCAs of water supply systems being complex requires very large data collection efforts, with multiple sources of information, many of them not public and requiring cooperation.

The economic consequences of drinking water supply system by LCA are mainly-

A. Reducing the wastage of water and conserv it for future

B. The economical use of water helps in maintaining the nature and don' affects the life science

C. The direct impact like a systamatic way of using water and helpingvin development of vicinity

D. Indirect impacts like revenue, water businesses, electricity projects are also satisfied

E. Agriculture is also possible.

And also other impacts like source conservation and environmental help are found.
