A trial conducted to examine the effects of watering Boran cattle once daily, once every two days and once every three days on birth and weaning weights, post-weaning growth and cow performance under extensive grazing conditions.

Limited awareness of environmental remote sensing’s potential ability to support environmental policy development constrains the technology’s utilization. This paper reviews the potential of earth observation from the perspective of environmental policy. A literature review of “remote sensing and policy” revealed that while the number of publications in this field increased almost twice as rapidly as that of remote sensing literature as a whole (15.3 versus 8.8% yr?1), there is apparently little academic interest in the societal contribution of environmental remote sensing.

The global livestock sector is diverse, undergoing rapid change and frequently

misunderstood. Livestock impact issues of major global concern, including food security,

poverty alleviation and environmental and human health. But these impacts differ greatly

across the globe, depending on factors such as the levels of wealth or poverty in a

country/region, the livestock commodity, consumer demands, the policy environment and

the livestock production system. This paper explores global trends in the livestock sector in

Research was done in the upper part of the Genale River basin in the Sidama Zone, Ethiopia. The research focussed on answering the question whether coffee-based agroforestry could ve an impact on the local hydrology. Discharge data, land use data and soil data was collected in the field and from literature and together put into a SWAT model to investigate the hydrological cycle of the basin. Several scenarios were created in which the amount of coffee in the area was altered.
