-Communal land is not transferable whereas individual land is transferable
-permanent crops are not usually planted on communal land while permanent crops can be planted on individual land.

(ii) Harnessing power in Biogas: Animal dung is mixed with water. It is then stored in airtight device/digester/dome. Anaerobic decomposition by microbes occurs. A colourless and odourless gas (methane) produced. The gas is then stored for use in cooking
