Ingeniería y Universidad - Engineering for development covers research focusing on sustainable human development. Targetted manuscripts consider Humans as final recipients of engineering research activity. This activity comes from any engineering field that provides solutions aimed at improving the quality of life by reducing risks, introducing new sustainable materials, more efficient use of natural resources, satisfying energy and food demands, increasing industry competitiveness and designing new safe jobs for human beings. Contributions with global relevance with potential of local application considering social, ethical, cultural, economic, environmental aspects are especially welcomed.
