Technological Solutions for Water Sustainability: Challenges and Prospects: Towards a Water-secure India
This book provides an overview of technical sustainable water management in the Global South, mainly in India, and is structured in five sections:
The current status and challenges for sustainable water management in India
New-age materials for water and wastewater treatment
New technologies for water and wastewater treatment
Sensors for water quality monitoring
Urban water management
Section 1 provides the latest information about the status and challenges for sustainable water management in India from the perspective of water quality, industrial and domestic wastewater treatment, urban water infrastructure and policy and governance towards water security. Section 2 discusses new framework solids for water purification, new materials for arsenic and fluoride removal, nanocomposites for water and wastewater treatment and removal of hazardous materials, and toxicity of these materials. Section 3 presents the new technologies developed for water and wastewater treatment; dealing with pulsed power technology, constructed wetlands, nutrient recovery, low-cost filters and pollution abatement using waste derived materials. Section 4 focuses on sensors, including the development of low-cost colorimetric sensors for eutrophying ions, sensors for conductivity and flow parameters, and multi-analyte assessment for water quality. Finally, Section 5 addresses the issues related to urban water infrastructure, sustainable urban drainage and integrated flood and water scarcity management.
This section also discusses virtual water.
The unique feature of this edited volume is its special perspective on emerging economies in the Global South, such as India. It provides information about adaption of technologies, development of new technologies, and management practices which are context driven and region specific. It also deals with economical and easy to use sensors for large-scale monitoring of water quality and water quantity parameters.

Floods and droughts are two contrasting extreme events that have become a major concern especially due to climate change and urbanization. These problems are due to distinct causes and effects at various places requiring different mitigation strategies. The risks due to floods and droughts cannot be eliminated but can be reduced or minimized. Transfer of the surplus water to areas of water deficit is a possible way of managing floods and droughts together. This would also help to create additional irrigational potential and promote hydropower generation to overcome regional imbalances. Other measures such as enhancing surface storage, managed aquifer recharge, interlinking of water bodies, and developing green infrastructures are practised globally under different names to combat these two extremes. This chapter presents a detailed insight into the effects and mitigation strategies of floods and droughts in general and with the case studies from the Republic of Korea and India.
