ABSTRACT
The United Kingdom Department of Health published the Dietary Reference Values for Food Energy and Nutrients which introduced a framework which valued food not according to commonly established social indices of taste and cost, but according to its fundamental value towards subsistence of a healthy human life. The Recommended Daily Allowance (RDA) encourages responsible eating habits by expressing the food people eat in terms of vitamins and minerals it contains in order to provide a healthy and balanced diet. Organic farming is commonly regarded to be more environmentally friendly than conventional intensive farming because it is free from any chemical interference. The pigeon towers are an important part of Irans architectural heritage. The Vertical Farm is a concept that seeks to address the major concerns of environmental degradation and failings of current food production system in our modern cities. Overcrowded slums in Nairobi have been part of campaign looking to educate malnourished urban dwellers on the potential of urban agriculture.
