Mobile pastoralism on communal grazing land in arid and semi-arid regions strategically exploits spatial and temporal variability of pasture resources. Since decades, Borana pastoralists in southern Ethiopia employ seasonal mobility to match livestock nutritional requirements with available grazing resources at any given time, and have developed sophisticated short and long term grazing itineraries. In recent times, however, seasonal mobility is decreasing drastically due to population growth, land privatisation, and governmental regulation. Livestock is the only asset under the pastoralists' full managerial control. The herd is an autopoietic system, renewing itself within the production cycle. At the same time, it is the pastoralists' capital asset, which transforms grazing into surplus and potential offtake, generating return on capital investment often as high as 20%. The generated products, goods, and services are traded (monetary income), bartered, and serve home consumption. Livestock reproductive performance being at the base of this, the present study aimed at analysing Borana cattle reproductive performance and demography under different restrictions of mobility.
