The Kenya Government has over a number of years pursued policies geared towards the promotion of secondary towns. Included in this strategy is the achievement of an orderly and coordinated urban land development. However, experience from these towns indicates that, planned land development has encountered a lot of bottlenecks particularly in relation to the institution of private ownership of land. This paper traces the land tenure systems that have existed in the Kenya’s secondary towns.

Fourty eight mature Ethiopian Menz ewes were used to investigate the effect on nutrition on oestrous and ovarian activity in tropical sheeA control group was fed on hay alone and a high nutrition group received an additional 400g per ewe per d of a concentrate feed providing 263 g crude protein/kg dry matter and 10.5 MJ metabolisable energy/kg dry matter. Half the ewes in each group interacted with harnessed vasectomized rams to detect oestrous, which was also verfied by weekly plasma progesterone assays. Ram presence did not depress feed intake or liveweight gain.

Vertisols and soils with vertic properties are an important soil group in the Ethiopian highlands. Poor drainage, soil, water and nutrient erosion are the most serious problems on highland Vertisols. Due to their high moisture- storage capacity, they have high production potential and this potential remains underutilised because of the difficulty of managing these soils. This paper summarises available information on chemical properties, N, P and mineralogy.
