What is bush fallow farming?
The bush fallow system of farming is widely practised in all the agroecological zones of the Volta Basin. Under this farming system, the family or household is the unit of decision making and production, and there is heavy reliance on personal and family labor for farming activities. The farming system is characterized by the use of simple tools and fire for clearing vegetation, and there is heavy dependence on the inherent fertility of the soil (Hunter 1969). The use of fire is a means of conserving energy, and the ash from burning makes some minerals (phosphates and potash) readily available for use by plants. Crops grown are basic food staples including cassava, yam, cocoyam, plantain, maize, and vegetables. Farm sizes are usually small, and the cropping system adopted is mixed, which help provide the subsistence needs of the family. Land ownership is communal, and the right to cultivate a piece of land is a birthright and/or with the consent of the land-owning group (Hunter 1969 ).

What is slash and burn agriculture?
Slash-and-burn agriculture is a generic term for agricultural systems in which the fallow vegetation is manually slashed, left to dry, and cleared from the field by burning before crop cultivation. “Swidden” is an English dialect word for a burned clearing; thus, swidden agriculture is a synonym for slash-and-burn agriculture. After a cropping phase, the land is abandoned to a fallow phase. Later, the cycle is repeated. Only those systems that alternate between crop and fallow phases are included in this definition. Multistory tree gardens, home gardens, and cocoa plantations, where crops are permanently cultivated, are excluded. With the exception of labor, slash-and-burn farmers use few or no external inputs. Implements such as machetes and hoes are most commonly used. Systems where machinery is used for clearance and irrigated systems are excluded from this definition. Not considered in this context are the systems such as the ankara of the Western Highlands in Cameroon, the nkule of the Tanzanian grasslands, and the gy of Ethiopia, in which vegetation is slashed, gathered, covered with soil, and then burned inside the soil mounds.
