Aquaponics: The Basics

Aquaponics is a technology that is part of the broader integrated agri-aquaculture systems discipline which seeks to combine animal and plant culture technologies to confer advantages and conserve nutrients and other biological and economic resources. It emerged in the USA in the early 1970s and has recently seen a resurgence, especially in Europe. Whilst aquaponics broadly combines recirculating fish culture with hydroponic plant production, the application of the term aquaponic is broad and many technologies claim use of the name. Combining fish culture with aquatic-based, terrestrial plant culture via aquaponics may be better defined via its nutrient resource sharing credentials. Aquaponics applies several principles including, but not limited to, efficient water use, efficient nutrient use, lowered or negated environmental impact and the application of biological and ecological approaches to agricultural fish and plant production. Water sources are important so that the nutrients required for fish and plant production are available and balanced, and system water chemistry is paramount to optimised fish and plant production. Systems may be configured in several ways, including those that are fully recirculating and those that are decoupled. Aquaponics importantly seeks to apply methods that provide technical, biological, chemical, environmental and economic advantages

Environmental Archaeology: What is in a name?

This book aims to thoroughly discuss new directions of thinking in the arena of environmental archaeology and test them by presenting new practical applications. Recent theoretical and epistemological advancement in the field of archaeology calls for a re-definition of the subdiscipline of environmental archaeology and its position within the practise of archaeology. New technological and methodological discoveries in hard sciences and computer applications opened fresh ways for interdisciplinary collaborations thus introducing new branches and specialisations that need now to be accommodated and integrated within the previous status-quo. This edited volume will take the challenge and engage with contemporary international discussions about the role of the discipline within the general framework of archaeology. By drawing upon these debates, the contributors to this volume will rethink what environmental archaeology is and what kind of input the investigation of this kind of materiality has to the reconstruction of human history and sociality
