Like most countries in sub-Saharan Africa, Ghana has recently transformed from being predominantly rural to having a majority of people living in cities. In the general absence of planning and infrastructure, urban growth leads to sprawl, which is likely to lead to the conversion of good agricultural land to urban purposes (Kusimi, 2008). Land beyond the former urban periphery may then transition to agriculture (Yorke & Margai, 2007; Pabi, 2007; Braimoh, 2004).
