This book, together with the game that forms part of it, tellsan important part ofthe story of Shikha Ecovillagein rural eastern India. The chosen focus of the story is water management. There are two reasonsfor this: firstly, in times of worsening climate change the use of freshwater is a major challenge, in India as well as in other parts of the world. Secondly, the story of water management is naturally interwoven with all the main activities at the ecovillage. Through this topic, the reader and player can get an overall idea of what life is like at Shikha. We hope that this will give valuable insights into our local area and generatefurther interest.There is a particularly strong link between water, energy and food. This is sometimes called the “water-energy-food nexus”. At Shikha Ecovillage, we see these relationships play out in a real-life example: we use electricity from solar panelsto pump water and distribute it for both domestic and agricultural use. The food we grow for our community depends on good management of the available water, and on understanding the impact of the dry season and the monsoon season. This Regen-D game points out both thestrengths and the vulnerabilities of our water management in this context.Part of the content of this book is the result of research (see the reference to research and development projects in the acknowledgements). However, this book is notan academic research paper. Instead, through the game format we want to presentthe story of how we experimented with water management and developed it on our sites in a way that is not merely an abstract intellectualsummary. We have integrated well-researched detail with multimodal content to give the playersa tangible experience.Compilingand organising the multimedia materials has taken as much effortas writing the book,if not more. These materials are central to the documentation of ourcase study and not a supplementary add-on.
