Abstract
ABSTRACT
A preliminary study on water resources for livestock rearing in SW Spain is presented. The
objectives of this work were to assess the availability of water for domestic animals in farms
and to explain whether water shortages are controlled by environmental factors or are also
related with land management. The study was carried out in 54 private farms of wooded and
treeless rangelands in Extremadura. Field work, digital topographic maps and aerial
photographs were used to assess the potential hydrological resources of each farm. The
water needs of livestock were estimated considering the number and species of animals per
farm, as well as other factors influencing their water consumption. Furthermore, semistructured
interviews were carried out in order to gather information about water
management. Results indicate that almost 20% of the farms suffer problems of water
availability in summer and almost 50% during droughts. Different solutions are adopted by
the farmers, including construction of infrastructure, bringing water from outside or moving
the animals to other areas. Data indicate a positive relationship between problems of water
supply and the degree of aridity. Data also point to a relationship with water consumption by
livestock and the availability of water by artificial ponds.
