Confronting South Africa’s water challenge: A decomposition analysis of water intensity

The Value of Free Water: Analyzing South Africas Free Basic Water Policy

This paper analyzes South Africa’s Free Basic Water Policy, under which households receive a free water allowance equal to the World Health Organization’s recommended minimum of 6 kiloliters per month. I structurally estimate residential water demand, evaluate the welfare e¤ects of free water, and provide optimal price schedules derived from a social planner’s problem. I use a unique dataset of...

Analysis of Quran and Hadith on Confronting Water Pollution Using Rainwater Catchment Systems

Today, water quality reduction and water pollution are some of the challenges in different countries around the world. One way to meet these challenges is to harvest and store rainwater using rainwater catchment systems. By collecting rainwater using rainwater catchment systems, water does not flow on the ground. Therefore, using the rainwater catchment system helps to prevent rainwater from mi...

Decomposition Analysis of Water Treatment Technology Patents

Water treatment technology development supports a steady, safe water supply. This study examines trends in water treatment technology innovations, using 227,365 patent granted data published from 1993 to 2016 as an indicator of changing research and development (R&D) priorities. To clarify changes in R&D priorities, we used a decomposition analysis framework that classified water treatment tech...

Water intensity of transportation.

As the need for alternative transportation fuels increases, it is important to understand the many effects of introducing fuels based upon feedstocks other than petroleum. Water intensity in "gallons of water per mile traveled" is one method to measure these effects on the consumer level. In this paper we investigate the water intensity for light duty vehicle (LDV) travel using selected fuels b...
