How can we help cities to get more sustainable through our food habits?
Cities rely on regional and international food production to feed their inhabitants. The food system includes everything from the production of food, its processing, consumption and waste management. Improving City/Region Food systems allows for ameliorating the sustainability of our cities, also in terms of safeguarding human rights or adapting to climate change. As every city and region is an unique context, challenges faced and solutions to answer cannot be homogeneous. However, we can lean from others by sharing ides and innovations to create a virtuous learning loop where every experience may help in shaping sustainable future cities. World population and its urbanization is increasing ...
Grafting as a Sustainable Means for Securing Yield Stability and Quality in Vegetable Crops
Vegetable growers around the world only collect, on average, half of the yield they would obtain under optimal conditions, known as yield potential. It is estimated that 60–70% of the yield gap is attributable to abiotic factors such as salinity, drought, suboptimal temperatures, nutritional deficiencies, flooding, waterlogging, heavy metals contamination, adverse soil pH and organic pollutants, while the remaining 30–40% is due to biotic factors, especially soilborne pathogens, foliar pathogens, arthropods and weeds. Under climate change forecasts, the pressure of biotic/abiotic stressors on yield is expected to rise and challenge further global food security. To meet global demand, sev...

Small-scale Aquaponic Food Production
This technical paper begins by introducing the concept of aquaponics, including a brief history of its development and its place within the larger category of soil-less culture and modern agriculture. It discusses the main theoretical concepts of aquaponics, including the nitrogen cycle and the nitrification process, the role of bacteria, and the concept of balancing an aquaponic unit. It then moves on to cover important considerations of water quality parameters, water testing, and water sourcing for aquaponics, as well as methods and theories of unit design, including the three main methods of aquaponic systems: media beds, nutrient film technique, and deep water culture. The publication d...
