The aim of this paper is to review the issues surrounding water security in terms of quantity and quality and its impact on food availability.
The research involved an examination and evaluation of existing literature so that the key elements of a water security policy model could be determined.
Water demand and availability is multifaceted and the degree of water security can be determined at a personal, national or international level. One of the key drivers of water security is the current and continued ability of water resources to meet the often conflicting needs of domestic supply, food production and amenity uses, including the requirement to irrigate food production areas in order to improve food yields and feed the growing global human population and mitigate the impact of any environmental change.
This paper provides an overview of the subject of water security and therefore will be of value to policy makers, academics or those developing environmental risk management strategies for organisations within the food supply chain.
