(c) Explain three reasons why horticultural farming is encouraged in Kenya.To earn foreign exchange which help to improve the economy. To create employment which enables people earn income hence improve their living standards/reduces unemployment. To provide raw materials which support the development of related industries. To enable farmers with small pieces of land earn high income. To improve food supply in the country thereby ensuring food security.

(Any 3 x 2 = 6 marks)

(d) Give three factors which favours beef farming in the Nyika plateau.Presence of watering points/rivers/swamps. There are large tracks of ﬂat land with natural grass. The local people who keep livestock as their occupation. The semi-arid conditions of the area favour beef cattle keeping.

(Any 3 x 1 = 3 marks)

a) Explain four ways in which land is being rehabilitated in Kenya.By ﬁlling open pits/land scaping in order to be used for farming/settlement. By constructing terraces thereby reducing the speed of surface runoff. By planting trees / grass strips on degraded land thereby protecting it against the agents of erosion. By building gabions in order to hold/trap the soil carried by water. By constructing dykes along river banks/dams across rivers in order to control ﬂoods. By supplying manure /fertilizer on derelict land in order to restore its fertility. By irrigating semi-arid areas/during dry seasons in order to provide water required for crop growth. Bush fallowing to allow land to regia.n fertility. Mulching / cover crops/ cut off drains to retain soil moisture/ add humus. Drainage trenches to remove excess water from the land. Controlled grazing to allow regeneration of pastures. (Any 4 x 2 = 8 marks)

(b) (i) State two ways in which the salinity of the polders is reduced in the Netherlands.

– Chemicals are applied to lower salts in the soils.

– Fresh water is ﬂashed to the soils to remove/dilute the excess salts.

– Reeds are planted to use up the excess salts.

– Continuous pumping of water from the polders.

(Any 2 x 1 = 2 marks)

(ii) Explain four ways in which the Zuyder Zee project beneﬁts the Netherlands. Reclamation has increased the size of the land which is used for farming/ settlement. The reclaimed land has increased agricultural output hence more food/ raw materials for industries.Damming created a freshwater lake thus improving the supply of water for domestic/industrial use/ lowering salinity of the soil. It has led to employment of many people thus improving their standards of living. Roads have been constructed thus improving transportation. Reclamation has created sceneries that have become tourists attractions thereby earning foreign exchange. Construction of the great dyke shortened the coastal distance. It also controlled the disastrous ﬂoods. (Any 4 x 2 = 8 marks)

(c) You intend to carry out a ﬁeld study on irrigation farming in Mwea Tebere Irrigation scheme.

(i) Identify the two types of hypothesis you would develop for the study. Alternative/substantive/positive.Null / negative. Question form. (2 x 1 = 2 marks)

(ii) Name three crops grown in the scheme you are likely to identify.Rice Maize Tomatoes Beans/peas Vegetables Water melons Onions (3 x l = 3 marks)

(iii) Give reasons why you would sample the area of study. (2 marks)It is cheaper to study portions of the scheme.It saves the amount of time spent on the study. I brings out the details of the area under study. It enables one to make generalised conclusion about the area under study. (2 x 1 = 2 marks)

9. (a) Deﬁne the term ﬁshing.It is the extraction/exploitation of aquatic animals/ﬁsh. (2 marks)

(b) Explain two ways in which each of the following factors negatively affect ﬁshing in Kenya.

(i) Agricultural activitiesPoor farming methods cause soil erosion thereby leading to siltation of the lakes/rivers which hinders the movement of ﬁshing vessels/ death of ﬁsh. Agro-chemicals used on farms were washed into the lakes/rivers thus polluting the water/kill ﬁsh/eutrophication. Abstraction of water from the river/lakes for irrigation reduces the level of the water thereby limiting the types of ﬁsh species.

(Any 2 x 2 = 4 marks)

(ii) Water Weeds

– The growth of the weeds on the surface of the water harbours dangerous animal/predators thereby scaring away the ﬁshermen.

– The weeds growing on the water form a thick barrier/insulate the water thereby hindering the amount of sunlight required for the growth of Planktons

– The weeds on the water choke the ﬁshing vessels thus hindering their movement.

– The Weeds compete for oxygen with ﬁsh which leads to death of ﬁsh.

(Any 2 x 2 = 4 marks)

(C) Use the map of North-West Atlantic ﬁshing ground to answer question (c) (ii) and (iii).

(i) Give three types of ﬁsh species caught in the North-West Atlantic ﬁshing ground.

– Shell ﬁsh

– Herring

– Cod

– Mackerel

– Haddock

– Menhaden

– Lobseters

(3 marks)

(11) Name the ocean currents marked.

M – Cold Labrador current (l mark)

N – Warm Gulf Stream (l mark)

(ii) Explain two ways in which the convergence of ocean currents marked M and N inﬂuence ﬁshing. (4 marks)

– It causes upwelling of water which increases supply of oxygen/minerals for Planktons required for growth of ﬁsh hence presence of alot of ﬁsh/ many species of ﬁsh.

– The warm current raises the temperature of the ocean water making it ice-free thereby encouraging ﬁshing throughout the year.

– The cold current carries minerals which encourage growth of Planktons thus food for ﬁsh thus a lot of ﬁsh.

– It causes cool conditions/temperatures thereby favouring the growth of Planktons required by ﬁsh hence presence of a lot of ﬁsh / many species. (Any 2 x 2 = 4 marks)

(d) Give three differences between ﬁshing in Kenya and Japan.

– In Kenya there is low level of technology/mechanization while in Japan there is advance/efﬁcient technology.

– In Kenya ﬁshing is done on small scale while in Japan ﬁshing is down on large scale.

– In Kenya there is a small domestic/external market while in Japan there is large domestic/external market.

– In Kenya few people market their ﬁsh through co-operatives while in Japan marketing is mainly done through co-operatives.

– In Kenya ﬁshing is mainly done near the continental shelf/shallow sea waters / lakes while in Japan ﬁshing it is mainly deep sea ﬁshing.

– In Kenya ﬁshermen face stiff competition from foreigners while in Japan there is little competition from foreigners.

– In Kenya there are few variety of marine species while in Japan the species are many.

– In Kenya the ﬁsh eating culture is limited while in Japan it is widespread.

– In Kenya there is limited research while in Japan it is extensive.

– In Kenya ﬁsh farming is less developed while in Japan it is highly developed.

(b) (i) Explain four negative effects of ﬂoods.

– Flooding leads to loss of life/destruction of property therebv causing human suffering/misery.

– It causes destruction of vegetation on slopes thereby enhancing soil erosion.

– It creates pools of water on the land surface forming breeding grounds for pests which causes diseases to people/animals.

– It leads to water logging/leaching hence causing soil infertility.

– It leads to destruction of acquatic habitats hence reduced ﬁsh production.

– It causes ﬂooding of settlements thereby leading to new temporary homes/ displacement.

– It destroys transport/communication network thereby hindering movement of goods/services.

– Floods pollutes sources of water/land which causes water borne diseasesl eyesore.

– Floods wash away crops resulting in food shortage.

(Any 4 x 2 = 8 marks)

State two measures being taken to combat lightning.
