Rainwater harvesting

"The collection of rainwater from a surface that allows for the rainwater to be stored and used at a later time. In a typical rainwater harvesting situation, rainwater is collected from an impervious surface such as the roof of a building and then stored inside of a tank or cistern. Rainwater can be collected from other surfaces as well. Other surfaces include parking lots, roadways, driveways, and even land surfaces (once surface runoff from the land surface begins). Rainwater can be harvested and stored for many uses including landscape irrigation, potable and nonpotable indoor use, and stormwater management. Harvested rainwater can be particularly useful when no other source of water supply is available, or if the available supply is inadequate or of poor quality." (Innovative Water Solutions, 2019)

Interview with Dr Khalid Mahmood, Assistant Professor at the University of the Punjab

Could you describe your professional career and/or personal experiences related to space technology and water? Where does your interest in those sectors come from?

I started my research career in 2013, with research interests revolving around various environmental concerns that were deeply rooted in water related issues of Pakistan. Having an educational background in Space Science, it was quite intuitive to possess understanding of the very high potential of applicability of Geospatial technologies in the water sector.

I should note that this interview does not aim to compare the San women of Platfontein with the Zulu women from Folweni as these are totally different communities. Also, as much as I am a Commissioner, this interview is not done on behalf of the Commission on Khoi-San Matters (CKSM) but on my personal capacity as a researcher and academic who has an interest on issues pertaining to women.

European Space Agency’s “Water Scarcity” Kick-Start

The challenge

Water is one of the most important substances on Earth and covers 70% of the planet. However, freshwater makes up a very small fraction with 97% being saline and ocean-based. While the amount of freshwater on the planet has remained fairly constant over time, the world’s population has exploded, meaning that freshwater is threatened by significant forces, like overdevelopment, polluted runoff, and global warming.
