This thesis examines water quality status and deterioration in the Upper-
Athi-Nairobi sub-catchments which covers an area of 1154.4 km2 with an annual
discharge rate of 99242 m3/year (9.9 X 104 m3/yr). It is based on field and
laboratory analysis of water quality parameters.
The subject matter includes the assessment of land use processes
responsible for water quality deterioration. These include Industrial and
Agricultural activities. The study demonstrates how useful industrial

Effects of soils, vegetation and land use on infiltration
rates and related soil physical properties of the semi-arid
Sirima and Hukogodo catchments in Laikipia district were
investigated. Representative six soils in Sirima and four
soils in Hukogodo, surveyed at detailed level, were assessed.
Within soil types, four site condition treatments with respect
to vegetation cover and land use designated as Tr_ee/Bush _(TB),
Open Grass (OG), Bare Ground (BG) and Cultivated Surface (CS) -

This paper describes the environmental degradation that has occurred in Kenya since early this century, initially due to the introduction of plantation farming. Forests have been further targeted for farmland, fuel wood, building materials and hardwood species. Range land species have also become threatened due to continued infiltration of the population. The discussion considers the efforts of the Kenyan government to legislate and administrate against the further loss of natural resources and the consequent development of environmental awareness among the populace.

The intent of this study was to examine the impact of
changing land use patterns on the numbers and distribution
of livestock and wild herbivores in the Tana River District,
Kenya.
A multi-method approach of aerial surveys,
questionnaires, interviews and secondary data sources were
employed to realize the objectives.
Results indicate that changes in land use patterns and
types have created conflicts that led to the reduction of
the range and affected distribution of pastoral livestock
