Seawater desalination of arid regions: comparing the policy of the Kingdom of Saudi Arabia and Indonesia

Abstract

Problems with clean water in coastal areas alongside an increase in population and community economic activities have diversified community activities. Coastal settlements bordering the high seas are characterized as arid areas with a lack of clean water. Here, the use of the range groundwater supply against seawater intrusion means that the water consumed by the community tastes salty and brackish. The availability of abundant seawater, processed through desalination technology, can be used to meet the daily clean water needs of coastal communities. Sustainable development goal (SDG) 6 Water and Sanitation is concerned with ensuring that everyone has access to clean water and sanitation. In this regard, desalination technology is considered viable to achieve the SDGs in the environmental sector. Some countries have focused on using desalination technology to achieve target 6.4 by 2030. This goal aims to improve the efficiency of water use to reduce the number of people experiencing clean water scarcity by ensuring a sustainable supply of fresh water. The objective of this study is to examine the application of seawater desalination technology for clean water in the Kingdom of Saudi Arabia (KSA) and Indonesia, and identify the implications of desalination policies in these countries. Comparative studies were conducted using secondary data and literature studies on transforming seawater into clean water with technology. KSA applies seawater desalination technology to meet water needs. However, in Indonesia, policymaking has not holistically examined the potential of using seawater desalination technology for clean water. Until now, unlike in the KSA, Indonesia has not addressed the importance of the use of desalination technology in state policy.
