upper areas experience reliable rainfall while middle areas, medium rainfall and lower<br />

regions unreliable and poorly distributed rainfall. The short rains October-December are<br />

more reliable than long rains (April-June).<br />

Temperatures in the highlands, range between 14 o c to 17 o c while those of the lowlands<br />

between 22 o c to 27 o c.<br />

Unusual climate variability incidences arising from climate change were evident during<br />

the 1997 elnino rains and the 2001 drought, when flooding, landslides, high levels of<br />

erosion resulted to damage of infra structure, and high levels of malaria. During the<br />

drought period food production declined and water quality went low leading to high<br />

incidences of waterborne diseases.<br />
