The relationships between precipitation and temperature in the central Sudano-Sahelian belt are investigated by analyzing 50 years (1959-2008) of observed temperature (Tx and Tn) and rainfall variations. At daily time-scale, both Tx and Tn show a marked decrease as a response to rainfall occurrence, with a strongest departure from normal 1 day after the rainfall event (−0.5 to −2.5 °C Sudano-Sahelian architecture refers to a range of similar indigenous architectural styles common to the African peoples of the Sahel and Sudanian grassland (geographical) regions of West Africa, south of the Sahara, but north of the fertile forest regions of the coast. This style is characterized by the use of mudbricks and adobe plaster, with The Sudano-Sahelian region falls within the Sudan and Sahel savanna ecological zones. The major occupation in the area is rain-fed farming with few engaging in fishing, trading, weaving, making cottage, etc. The area enjoys tropical continental climate with two distinct seasons, wet and dry seasons. The wet season lasts for only 3-4 months Many studies on the Sudano-Sahelian ecological zone (SSEZ) of West Africa in general, and Nigeria in particular, have established a general trend in rainfall towards aridity (Adejuwon et al., 1990; Folland et al., 1991; Nicholson, 2001; Hulme et al., 2001). Recently however, some scenarios (based on greenhouse gas emissions) have suggested that the observed trend towards aridity will be put on Hulme M (2001) Climatic perspectives on Sahelian desiccation: 1973-1998.
