“…Water use can be mitigated through the use of more water-efficient growing systems (such as hydroponic systems), though these can result in increased energy demand in pumping and lighting, and associated GHG emissions. For example, hydroponic 13 systems have been shown to have lower water demand than soilbased production, in addition to avoiding the need for a solid growing medium and the associated energy inputs of its provision (Albaho et al 2008). However, Barbosa et al (2015) have modeled energy and water demand for hydroponic and conventional production systems for lettuce; while water demand was reduced by 92% (250 to 20 l kg −1 y −1 ), energy demand increased by 8100% (1100 to 90 000 kJ kg −1 y −1 ), due primarily to heating and cooling loads (74 000 kJ kg −1 y −1 ), artificial lighting (15 000 kJ kg −1 y −1 ) and circulating pumps (640 kJ kg −1 y −1 ).…”

“…With respect to soilless production systems, Albaho et al (2008) state that aeroponic 15 systems require an uninterrupted electrical supply but it is unclear as to whether this energy demand is offset by lower inputs and higher yields relative to conventional controlledenvironment or hydroponic systems. A summary of the energy implications of production methods is provided in table 3, along with estimates of energy implications from efforts to scale up UA in table 4.…”

There is an increasing global interest in scaling up urban agriculture (UA) in its various forms, from private gardens to sophisticated commercial operations. Much of this interest is in the spirit of environmental protection, with reduced waste and transportation energy highlighted as some of the proposed benefits of UA; however, explicit consideration of energy and resource requirements needs to be made in order to realize these anticipated environmental benefits. A literature review is undertaken here to provide new insight into the energy implications of scaling up UA in cities in high-income countries, considering UA classification, direct/indirect energy pressures, and interactions with other components of the food-energy-water nexus. This is followed by an exploration of ways in which these cities can plan for the exploitation of waste flows for resource-efficient UA.Given that it is estimated that the food system contributes nearly 15% of total US energy demand, optimization of resource use in food production, distribution, consumption, and waste systems may have a significant energy impact. There are limited data available that quantify resource demand implications directly associated with UA systems, highlighting that the literature is not yet sufficiently robust to make universal claims on benefits. This letter explores energy demand from conventional resource inputs, various production systems, water/energy trade-offs, alternative irrigation, packaging materials, and transportation/supply chains to shed light on UA-focused research needs.By analyzing data and cases from the existing literature, we propose that gains in energy efficiency could be realized through the co-location of UA operations with waste streams (e.g. heat, CO 2 , greywater, wastewater, compost), potentially increasing yields and offsetting life cycle energy demands relative to conventional approaches. This begs a number of energy-focused UA research questions that explore the opportunities for integrating the variety of UA structures and technologies, so that they are better able to exploit these urban waste flows and achieve whole-system reductions in energy demand. Any planning approach to implement these must, as always, assess how context will influence the viability and value added from the promotion of UA.

“…However, sustainable intensification differs from conventional agriculture in its greater emphasis on technologies and practices that reduce resource use, protect ecosystem functions, and build resilience against shocks like climate change (Balwinder-Singh, Humphreys, Gaydon, & SudhirYadav, 2015;Fish, Winter & Lobley, 2014;Lal, 2015;Rochecouste, Dargusch, Cameron, & Smith, 2015;van Ittersum, Cassman, Grassini, Wolf, Tittonell, & Hochman, 2013). Some of these technologies, such as biological control, protected production systems, and soilless production systems, excite little controversy as legitimate components of sustainable agriculture (Albaho, Thomas, & Christopher, 2008;del Amor, López-Marin, & González, 2008;Delgado & Berry, 2008;Maurino & Weber, 2013;Pinkington, Messelink, van Lenteren, & Le Mottee, 2010;Pliego, Ramos, de Vicente, & Cazorla, 2011;Rovira-Más, & Sáiz-Rubio, 2013;Wang & Pang, 2013;Yang et al 2014;). More controversial, a growing number of proponents of sustainable intensification are convinced that application of biotechnology is a necessary element in any strategy to meet world food demand (Albajes et al, 2013;Bennett, ChiHam, Barrows, Sexton, & Zilberman, 2013;Berkhout, 2002;Flavell, 2010;Jacobsen, Sorensen, Pedersen, & Weiner, 2013;Mackey & Montgomery, 2004;McGloughlin 2010;Teixeira, Proença, Crespo, Valada, & Domingos, 2015;Wield, Chataway & Bolo, 2010).…”

“…Choi et al [23] concluded that FAI technique for coir substrate was best in hydroponics due to sustainable use of water and fertilizers in strawberry. Albaho et al [24] concluded that continuous sub irrigation capillary system is the best among hydroponics in strawberry.

Hydroponic systems for crop production are nowadays essential to maximize yields. Sometimes, the benefits of hydroponics have been questioned by the researchers as compared to growing of crops in other soilless culture. The growers raised the crops through hydroponics system get yields more compared to conventional practices as hydroponically grown plants dip their roots directly into nutrient-rich solutions. Therefore, the aim of the current chapter is to provide accurate and updated information about their different nutrients and their composition used hydroponically compared to conventional production mode. This chapter will be divided as the following sections: (1) rationale, (2) nutrient solution technique, and (3) work done on fruit crops. With this chapter, we hope to present an updated information, comparing hydroponic versus conventional technique.
