A study was conducted to track a group of grazing cows by GPS-GPRS technology. GPS devices were placed in the neck of 3 non-gestating and non-lactating Morucha cows (averaged 8 years old). The GPS units emitted data regarding animal position every 10 minutes for a period of 28 days in which the animals could range freely in the experimental farm. Data were processed using the appropriate software to generate parameters related to animals’ activity, such as velocity of movement or estimated grazing area.

Despite their ecological, economic and social importance, Mediterranean grasslands continue to receive limited scientific, political and media attention. Grasslands are typically viewed as underutilized space, able to be transformed into more “valuable” land by placing it under cultivation, transforming it into forest land and/or privatizing it. This paper synthesizes a number of pertinent issues in relation to social and economic systems on grasslands within the southern Mediterranean region.

The potential of remote sensing for the recommendation and monitoring of irrigation practices is irrefutable. GIS have enabled the development of operational spatio-temporal tools for monitoring agricultural activity which can overcome the uncertainty brought about by problems related to water scarcity and increasing drought events. This paper presents an operational methodology for estimating actual evapotranspiration from Landsat images, and its application in the Region of Murcia (Spain).
