      • harvesting of crops
      • feeding and handling of animals

3. Why is agriculture very important to the economic development of Kenya (5mk)
   • food supply
   • source of employment
   • provision of foreign exchange
   • source of raw materials
   • Provision of market for industrial goods
   • source of money or capital
4. Name and explain three methods of farming (6mks)
   • Mixed farming-growing of crops and rearing of animals on the same farm
   • Nomadic pastralism-moving of animals from one plce to another on searching of fresh pasture and water
   • Shifting cultivation-farming on a piece of land continuously until it is exhausted after which the farmer moves to a more fertile ground
   • Organic farming- growing of crops and rearing of animals without using agricultural chemicals
   • Agroforestry- growing of trees and crops and keeping of animals on the same piece of land.

   2. farming and extensive farming (2mks)
      intensive-system which requires high capital and high labour invest ment per unit area, results into high yields
      extensive-requires large tracts of land, low capital investment low labour and low yields
   3. Pastoralism and aquaculture (2mks)

      ranching- keeping of livestock in marginal range areas
   5. Small scale and large scale farming (2mks)
      small scale-type of farming practised on small arearea piece of land
