A few days back an article was published on this blog about water scarcity and rain water harvesting in FATA, some of the friends have shown deep interest in the matter and seem enthusiastic to do some thing. Their enthusiasm is highly appreciated, but at the same time i want to realize to them some possible methods of rain water harvesting in FATA.
- Small scale household level rain water harvesting is to be promoted in addition to communal water harvesting.
- In communal rain water harvesting schemes indigenous and local material must be used. Specially those stones should be used in construction of structures which are lying in the flood streams.
- No explosive material to be used for collection of stones, specially in FATA, as stones of various sizes are freely available in each stream.
- While constructing rain water harvesting structures slope of the catchment area, and volume of the structure should be taken in to consideration.
- Possibilities of future flooding and possible damages down stream should be minimized through proper designing.
- In addition to rain water harvesting some measures for increasing surface vegetation both up stream and down stream must be facilitated to help in mitigating the global climate changes.
These are recommendation for people who want to work on rain water harvesting. Now for the developed countries all the environmentalist should build a pressure to allocate significant budget for research on recycling of the carbon that they emit regularly. The scientists should be motivated for exploring possibilities of directly traping down the carbon dioxide and carbon monoxide and processing them for other uses such as fertilizers, or fuels even.
What we need for mitigating the global climate changes is increasing awareness, taking small steps ourselves, and advocating with the most powerful actors who are causing degradation. In this way we can make the water, air and planet more sustainable for our coming generations.
