Groundwater extraction through electrically operated tubewells offers a resilient source of irrigation supply in arid regions especially during droughts. However, interrupted and low-voltage electric supply with limited availability and frequent trips increases repair and maintenance costs of tubewell irrigation and reduces tubewell discharge resulting in less-efficient and non-uniform water application. This study evaluates performance of an indigenous system of groundwater irrigation that was evolved over the generations in arid region of Gujarat, India to address electricity-triggered issues of irrigated agriculture. In this system, groundwater extracted during electricity availability hours is stored in surface reservoirs for later supplying to irrigate crops under gravity flow irrespective of electricity availability. A comprehensive survey of the indigenous system is conducted in a village of Gujarat to make inventory of all tubewells and storage reservoirs about their depth, size, pump type and horsepower, command area, crops, irrigation timing and frequency, etc. Discharge of tubewells was measured and their locations were recorded. Results revealed that the indigenous system is advantageous over the direct tubewell-irrigation in terms of 37.4% higher water-delivery rate and 50% more average irrigation capacity. These findings prove adequacy of the indigenous system in regulating irrigation supplies to deal with electricity-induced intricacies of irrigated agriculture. Amount of water lost through unit area of earthen (seepage and evaporation ~2.77 m) and masonry (evaporation ~1.22 m) reservoirs collectively accounts for a negligible proportion (0.9%) of groundwater draft. Furthermore, a methodology is devised to precisely estimate village-level groundwater draft for irrigation, which is validated by 0.9% deviation between observed and predicted values of groundwater draft. Moreover, the indigenous system is simple, cost-effective and easy to implement in other parts of the world especially in arid regions of the developing countries where low-voltage and intermitted electricity supply persists.

Groundwater for Sustainable Livelihoods and Equitable Growth explores how groundwater, often invisibly, improves peoples’ lives and livelihoods. This unique collection of 19 studies captures experiences of groundwater making a difference in 16 countries in Africa, South America and Asia. Such studies are rarely documented and this book provides a rich new collection of interdisciplinary analysis. The book is published in colour and includes many original diagrams and photographs.
Spring water, wells or boreholes have provided safe drinking water and reliable water for irrigation or industry for millennia. However, the hidden nature of groundwater often means that it’s important role both historically and in the present is overlooked. This collection helps fill this knowledge gap, providing a diverse set of new studies encompassing different perspectives and geographies. Different interdisciplinary methodologies are described that can help understand linkages between groundwater, livelihoods and growth, and how these links can be threatened by over-use, contamination, and ignorance.
Written for a worldwide audience of practitioners, academics and students with backgrounds in geology, engineering or environmental sciences; Groundwater for Sustainable Livelihoods and Equitable Growth is essential reading for those involved in groundwater and international development.

Kachchh, the westernmost district of India is historically known for its unique landscape, distinct traditions and arid climate. For a long time, the arid region of Kachchh had limited economic growth and limited habitation due to water scarcity caused by erratic rainfall. In 2001, the seismically active region of Kachchh experienced a large earthquake measuring 7.7 Mw but, the region has shown considerable development post-disaster. Growth strategies for agriculture, manufacturing and tourism implemented by the government and supported by industries and other agencies have not only made the region a dynamic economic hub in the state of Gujarat, but also has highlighted the long-neglected region on the world map. Due to the lack of perennial surface water availability and limited rainfall, the development has been fuelled by exploiting the groundwater resources to a great extent. The objective of this chapter is to highlight groundwater use in Kachchh, known as one of the most arid regions of India with low rainfall and high variability. Groundwater is playing a vital role in meeting the demand for all societal usage, irrigation, domestic requirements and industries. The authors highlight how the region is blessed with a suitable geological formation, forming a potential freshwater aquifer system which has served society for centuries even with a grossly adequate recharge. They highlight the importance of looking into the sustainable use of groundwater, a priceless natural resource of the region.
