Tanzania like the other African countries mainly depends on Agriculture to support its economic activity and earn foreign exchange earnings. It has over 44 million hectares of arable land out of which only 33 percent is presently under cultivation. This highlights the potential of agriculture the country holds. The nine main food crops in Tanzania are , sorghum , millet , rice, wheat, beans, cassava, potatoes, and bananas.
Presently, the country is marred by a few challenges like primitive approach, diversity in soil, droughts and floods that lend trouble to agriculture. Dar es Salaam is most important urban centre in Tanzania and accounts for about 35% of its total urban population. It is here that home gardening and urban farming is making serious waves as a means to generate income and reduce costs.
