The world today faces increasing freshwater shortages due to a growing global population, climate change, pollution, rising consumer demand, and resource exploitation. To combat this, water desalination has become a crucial method for producing freshwater. Meeting water demands efficiently, cost-effectively, and sustainably requires the right combination of renewable energy and desalination technology.

Desalination is essential for addressing the rising global need for freshwater by converting seawater or brackish water into potable water. This technology is particularly vital in arid and water-stressed regions. The primary goal of desalination is to remove dissolved salts and other impurities from water, making it suitable for drinking, irrigation, and industrial use. Techniques such as reverse osmosis, distillation, and electro dialysis are used to separate salts and contaminants, resulting in clean and usable freshwater.

While desalination offers a reliable solution to water shortages, it also presents challenges. The process can be energy-intensive, raising concerns about environmental impact and sustainability. Additionally, disposing of the brine byproduct generated during desalination poses environmental challenges. Despite these issues, advancements in desalination technologies, ongoing research, and increasing global water demands have driven the continued development and adoption of desalination as a crucial component of water resource management. As water scarcity issues escalate, desalination’s role in providing a sustainable and diversified water supply is likely to become even more significant.

Another significant issue along the coastal areas is saltwater intrusion, posing both human-made and natural challenges. Saltwater intrusion is the process by which seawater enters and contaminates freshwater aquifers, making the water unsuitable for drinking, irrigation, and other uses. This phenomenon is a significant problem for contamination of freshwater supplies, ecosystem disruption and soil salinization, increased costs for water treatment and property damage, etc.

To address these issues, a workshop has been planned to exchange experience and practice, to educate students and also to inform other stakeholders about environment-friendly technologies for desalination and saltwater intrusion. This webinar, jointly organized by IAHR, the National Institute of Ocean Technology, India (NIOT), the Indian Institute of Technology Madras (IITM), and Anna University, will cover the following topics:

  • Various desalination technologies and projects

  • Renewable energy-powered desalination

  • Experience and practice associated with saltwater intrusion control

  • Sustainable solutions and technologies
