Give five reasons why afforestation is being encouraged in Kenya

KCSE Geography Paper 2 2002 Section B Question 6.

Use the photography bellow  to answers the questions that follows;

Identify the type of photograph.

• Ground / close up photograph

Evidences from the photograph

• Forest
• Workers/people
• Logs/heap of logs
• Cleared area
• Stumps
• Cleared area
• Poles
• Litter
• Sky/clouds/horizon

​iii) Describe the appearance of the forest shown on the photograph.

• The trees have straight sterns
• The forest has tall trees
• The trees are close to each other/thick forest
• The trees are almost the same height.
• They are of the same species.
• There are some scrubs/undergrowth
• Some trees are conical shaped
• Trees are thin

​b) i) What is Agro – Forestry?

• Agro forestry is a land use system, which enables the production of trees, crops and livestock on a given unit of land either in spartial arrangement or/over time to maximize productivity and sustainability of the land.

​ii) Give five reasons why afforestation is being encouraged in Kenya

• To ensure continuous supply of wood fuel/timber/herbal/medicine/raw material for paper making.
• To protect the soil from erosion.
• To protect the water catchment areas/create microclimates/maintain hydrological cycle.
• To create scenic beauty.
• To expand the habitat for wildlife/conservation of wildlife.
• To create employment opportunities.
• To reduce importation of forest products/save foreign exchange.

​c) Compare forestry in Canada and Kenya under the following sub – headings.
i) Tree harvesting
ii) Transportation of logs.

(i) Trees harvesting. 

• In Canada, harvesting is done through clear cutting while in Kenya it is selective logging.
• In Canada logging is done in winter while in Kenya cutting takes place throughout the year.
• In both countries, commercial logging is mechanized.
• N.B. Comparisons must be complete.

(ii) Transportation of logs.

• In Canada, logs are transported using melt water/rivers while in Kenya transportation is by road.

​d) Explain two problems that affect forestry in Canada.

• Accidental fires which consume large tracts of the forests reduce the area under the forests.
• The cold climate leads to trees taking too long to mature which delays harvesting time.
• Rugged landscape especially in the mountainous areas hinder smooth exploitation of the forests.
• Northern parts are inaccessible in winter due to very cold climate conditions.
• Overexploitation in some areas have created a shortage in some of the true species while taking a long time to mature.
