Smart Farming is the new term in the agriculture sector, aiming to transform the traditional techniques to innovative solutions based on Information Communication Technologies (ICT). Concretely, technologies like Unmanned Aerial Vehicles (UAVs), Unmanned Ground Vehicles (UGVs), Image Processing, Machine Learning, Big Data, Cloud Computing, and Wireless Sensor Networks (WSNs), are expected to bring significant changes in this area. Expected benefits are the increase in production, the decrease in cost by reducing the inputs needed such as fuel, fertilizer and pesticides, the reduction in labor efforts, and finally improvement in the quality of the final products. Such innovative methods are crucial in recent days, due to the exponential increase of the global population, the importance of producing healthier products grown with as much fewer pesticides, where public opinion of European citizens is sensitized. Moreover, due to the globalization of the world economy, European countries face the low cost of production of other low-income countries. In this vein, Europe tries to evolve its agriculture domain using technology, aiming at the sustainability of its agricultural sector. Although many surveys exist, most of them tackle in a specific scientific area of Smart Farming. An overview of Smart Farming covering all the involved technologies and providing an extensive reference of good practices around Europe is essential. Our expectation from our work is to become a good reference for researchers and help them with their future work. This paper aims to provide a comprehensive reference for European research efforts in Smart Farming and is two-fold. First, we present the research efforts from researchers in Smart Farming, who apply innovative technology trends in various crops around Europe. Second, we provide and analyze the most significant projects in Europe in the area of Smart Farming.

智能农业是农业领域的新名词，旨在将传统技术转变为基于信息通信技术（ICT）的创新解决方案。具体而言，无人驾驶飞机（UAV），无人地面飞行器（UGV），图像处理，机器学习，大数据，云计算和无线传感器网络（WSN）等技术有望在这一领域带来重大变化。预期的好处是产量增加，通过减少所需的投入（例如燃料，肥料和杀虫剂）减少成本，减少劳动强度以及最终提高最终产品的质量。由于全球人口呈指数增长，这种创新方法在最近几天至关重要。生产含农药少得多的健康产品的重要性，这引起了欧洲公民的舆论关注。此外，由于世界经济的全球化，欧洲国家面临着其他低收入国家的低生产成本。因此，欧洲试图利用技术来发展其农业领域，以实现其农业部门的可持续性。尽管存在许多调查，但大多数调查都针对智能农业的特定科学领域。对智能农业的概述涵盖所有涉及的技术，并为欧洲的良好实践提供广泛的参考至关重要。我们对工作的期望是成为研究人员的良好参考，并为他们的未来工作提供帮助。本文旨在为欧洲在智能农业方面的研究工作提供全面的参考，有两个方面。首先，我们介绍了智能农业研究人员的研究成果，他们将创新技术趋势应用于欧洲各地的各种农作物。其次，我们提供并分析欧洲在智能农业领域中最重要的项目。
