INTRODUCTION
INTRODUCTION
The students of environmental science class together with environmental resource conservation students set out for three and a half day field trip a field trip in different ecosystems mainly in the rift valley region. These ecosystems included; the savanna, aquatic, and forest ecosystems
AIM
To familiarise the students with ideal situation on how human activities and other factors have led to different environmental impacts on the above mentioned ecosystems. To provide practical knowledge on how these activities have led to environmental degradation.
OBJECTIVES
Observing the vegetation structure in various ecosystems and identifying the dorminant plant and animal species
To find out the main socio-economic activity in the areas visited. And divulging the environmental impacts of the human activities on the environment
Identify other environmental problems in the area and observing efforts being made to address the environmental problems
To suggest other mitigation measures on these problems
METHODOLOGY
The main method of acquisition of data was observations photographing and interrogating the local communities living in these ecosystems
RESULTS AND DISCUSSION
SAVANNA ECOSYSTEM
(a)Mai mahiu
Vegetation structure is mainly comprised of shrub, herbs, grass and few scattered trees. Dorminant tree species are the acacia (Senegal,tortilis) and the euphorbia species. Small animals like the rodents and few bird species are also found here. The main socio-economic activity is cultivation though pastoralism is also practised.several problems were noted for example cultivation on the slopy areas which has led to massive soil erosion sedimentation of few streams leading to loss of biodiversity.overgazing and deforestation has also caused major destruction in this ecosystem. Road construction has to erosion leading to sedimentation. No effort was noted as far as conservation of the environment is concerned.Slopy
