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.
