Sack Farming: Innovation for Land Scarcity Farmers in Kenya and Ghana Abstract: Food insecurity and poverty create environmental challenges in many developing countries. These challenges become compounded as agriculture, urbanization and industrialization compete for space. In this restrictive context, agricultural land use extensification become superseded by intensification. Nonetheless, there is hunger and starvation in Africa and other areas which practice less agricultural intensification. As a result, innovations are required to address food insecurity and poverty. In this regard, urban agriculture plays significant role as exemplifies by green rooftop farming, backyard gardens, community gardens, commercial farms and public institutional gardens. A latest addition to urban farming (sack farming – garden in a sack) has come to supplement urban vegetable production by making use of urban soils, spaces and waste. Examples of sack farming in large African cities like Nairobi, Kenya and refugee camps in Uganda offer very useful lessons particularly for the latest introduction in Ghana. This paper provides a review.
