The
Northern Region is much drier than southern areas of Ghana, due to its
proximity to the Sahel, and the Sahara. The vegetation consists
predominantly of grassland, especially savanna with clusters of
drought-resistant trees such as baobabs or acacias. Between May and
October is the wet season, with an average annual rainfall of 750 to
1050 mm (30 to 40 inches). The dry season is between about November
and April. The highest temperatures are reached at the end of the dry
season, the lowest in December and January. However, the hot Harmattan
wind from the Sahara blows frequently between December and the beginning
of February. The temperatures can vary between 14°C (59°F) at night and
40°C (104°F) during the day.
Months
of inadequate household food provisioning has been defined as the time
between stock depletion and the next harvest (Bilinsky and Swindale,
2007). It is usually used as a measure of food insecurity in a highly
subsistence-oriented area where production is primarily for home
consumption and households do not make significant sales or purchases in
the market. Quaye (2008) reported that most farmer
households experience significant degree of food insecurity with food
insecure periods spanning between 3 and 7 months (Fig. 2). Upper East
Region was the worst affected as it experienced the longest food
shortage period of 6 months. The Northern and Upper West regions
recorded 5 months of food inadequacy.
