Abstract
Change in climate, increasing world population and industrialization have placed considerable stress on water availability at certain places. Water Footprint accounting is a reliable technique that can be used for a better water management. This study focuses on establishing a doable methodology on water footprint accounting and assessment for direct water consumption from domestic and institutional sectors located in an urbanized environment such as Klang Valley, Kuala Lumpur. It includes investigation of Water Footprint at domestic household, schools, colleges, terminals and offices in Klang Valley. The value of water consumption, water production and water pollution will be determined using Hoekstra’s approach for green water, blue water and grey water. In addition, findings from this study will be linked to two other elements namely energy and food. This link is named as Water-Energy-Food Nexus. This study will establish the quantity and criteria of Water-Energy-Food Nexus specifically tailored to domestic and institutional sectors in Klang Valley.
Highlights
Water Footprint (WF) concept was introduced in year 2002 at the International Expert Meeting on Virtual Water Trade,that was held in Delft, the Netherlands (Hoekstra, 2003)
Water use is measured in terms of water volume consumed and water polluted per unit of time
First objective is to list all the variables that may affect the water usage, food intake, energy consumed of consumer in domestic and institutions sector of Klang Valley
Summary
Water Footprint (WF) concept was introduced in year 2002 at the International Expert Meeting on Virtual Water Trade,that was held in Delft, the Netherlands (Hoekstra, 2003). Aldaya (2010), water footprint is an numerical indicator use for a consumer or producer (the data can be individual or a group data). Water use is measured in terms of water volume consumed and water polluted per unit of time. A water footprint can be calculated for process, product, consumer, group of consumers such as municipality, province or state and producer such as public organization and private enterprise. WF can be clasify into three kinds which are green, blue and gray water. The green water is the soil water held in the unsaturated zone, produced by rainfall and available to plants only. The grey WF is the volume of water needed to dilute a certain amount of pollution
