Water Works Design and Supervision Enterprise b) Land Use and Vegetation Land use / cover types of the Dire Dawa Administrative Council is grouped into four major classes. They are designated as urban built up, cultivated land, physiognomic vegetation types and Bare land. These major classes have been subdivided in Twelve (12) mapping units. The extent in hectare and the percentage coverage from the total study area of each of the identified mapping units are shown in Table 8.

Water Works Design and Supervision Enterprise 2.4 AGRICULTURE, LIVESTOCK AND ENERGY 2.4.1 Agro-Climatic Zones Combining seven major moisture and three thermal zone units resulted in the identification of eighteen major agro-ecological zones for the whole country. Sub agroecological zones were determined by combining the 18 major zones with the seven physiographic regions. Then by superimposing the seven physiographic regions map with the 18 major agro-ecological zones map, 49 sub-zones are recognized in the country. Of these five major and six sub-agro-ecological zones were identified in the Dire Dawa Administrative Council (Table 9 and Fig.8).

In semiarid to arid condition where rainfall is less, pastoral livestock farming system becomes predominant. There fore, there are two distinct farming systems in the Administrative Council. These farming systems are Transhumant in the lowland and mixed farming in the mid-altitude. The mid altitude production system is cereal and livestock production system, while the low land is dominantly Transhumance/pastoral. The pastoral production system covers ones 10 peasant association (PAs). Out of the total livestock production in the Administrative Council, 51.3% 48.62% and 4.20% are found in the mid altitude, lowland and urban Kebeles respectively.
