The efficiency of a recirculation system for the cultivation of C. auratus, fed with natural and artificial diets was evaluated. The experiment consisted of four treatments with four replicates. The first two treatments used recirculation system and the last two static system. In the first and fourth treatment, animals were fed with brine shrimp biomass (50% CP), while in the second and third treatments a commercial flake ration (42% CP) was used. At the end of cultivation (60 days), water samples were taken from all experimental units and subjected to standard plate count for determining the density of mesophilic bacteria. Final weight (g), final length (cm), specific growth rate (% day -1) and weight gain (%) were significantly different (p | A eficiência de um sistema de recirculação para o cultivo de C. auratus, alimentados com dieta natural e artificial foi avaliada.

Providing the water needed to produce food for more than 9 billion people by 2050 seems simple: agriculture must produce more food with less water. However, three complex issues are involved: First, water, food production and rural development do not have a simple correlation. Second, there are interactions between processes at local, basin and global scales. Third, change involves people in complex networks of institutions. The Challenge Program on Water and Food brings together agriculturalists, hydrologists and development specialists in a global-to-local programme that focuses on change through institutions. We believe that this scale, complexity and involvement are necessary to deliver plausible change.

Global food demand is increasing and changing rapidly as a result of multiple drivers as population growth or urban dietary shifts. Managing food consumption (people’s eating habits) might deliver important co-benefits from a water perspective. Many recent studies have addressed the relationship between diet habits and associated water impacts. The goal of this study is to assess and compare the water footprint (WF) of two recommended diets (Mediterranean and American) in Spain and US. Moreover also focuses on assessing the WF of the food consumption and its associated food waste in Spanish households during one year. Our results show that the American diet has a 29% higher WF, regardless of products' origin. Food consumption and waste WFs in Spain are 3,302 and 131 litres/person day respectively. A shift back to a Mediterranean diet, in which fruits, fish and vegetables account for a larger share of the food intake, would deliver great water savings.

"This Comprehensive Assessment of Water Management in Agriculture, involving more than 700 leading specialists, evaluates current thinking on water and its interplay with agriculture to help chart the way forward. It offers actions for water management and water policy - to ensure more equitable and effective use. This assessment describes key water-food-environment trends that influence our lives today and uses scenarios to explore the consequences of a range of potential investments. It aims to inform investors and policymakers about water and food choices in light of such crucial influences as poverty, ecosystems, governance, and productivity."--Jacket.
