The purpose of this paper is to consider implementation of Artificial Intelligence as a part of Precision Dairy Farming, as a way of processing, analyzing and managing Big data, in order to enable sustainable dairy cattle farm. Increasing the volume of livestock production in the future and measuring the level of environmental impact becomes one of the most pressing concerns. The aim is to evaluate the impact of animal's production level on the ammonium pollution from dairy cattle farm using precision dairy farming technologies. The results indicate significant variability in estimated ammonium pollution from dairy cattle farms due to the animal's production indicating positive correlation between daily milk production and ammonium pollution. The test day records, as Artificial Intelligence application in precision dairy farming could be used both for assessing the ammonium pollution from farms and timely prevention and correction of inadequate management towards sustainable dairy production systems.

In this paper we analyze and evaluate the impact of the new technologies of the Fourth Industrial Revolution (4IR) on tourism of protected areas and the future of ecotourism and tourism of protected areas. The transformational role of the 4IR technologies has huge potential effect on managing protected areas. Using new technologies in ecotourism and tourism in protected areas will greatly improve management of protected areas. In this paper we analyzed dominant technological trends and key concepts in tourism industry. We also presented case study of the applying new technologies in SNR Zasavica in Serbia. In future, the new concepts and the Smart Tourism paradigm will transform the ecotourism and tourism of protected areas in the way of creating fully automated technological ecosystem intended for managing sustainability of the protected areas environment. There are several emerging concepts that have a capacity to completely and radically change the way of the business as we know it and will surely have great impact on tourism and ecotourism in the future.
