Land uses
Brief description
1
Cultivated land
This includes the area utilized for crop production under rain-fed conditions. Mixed cropping, in which khat is intercropped with sorghum, is the most common cropping system. Only a few quantities of OM are reimbursed to the soil, and residue of crop is practically never changed to the soil since it is used for other reasons such as fuel wood, feed of animal, and construction material (e.g., sorghum). The farmers use mostly chemical fertilizers (DAP, urea) for crop production rather than organic fertilizers
2
Grazing land
Land utilized for community cattle grazing and achieved through a controlled system in which livestock is restricted in stalls and fed with a carry and cut system
3
Fallow land
This comprises land that was formerly heavily cultivated but is now uncultivated and in need of rehabilitation
