Agricultural information is an important part of modern agricultural construction, and the development of a- gricultural industry is becoming more and more deeply with the application of infor- mation technology. This paper reviewed the concept and characteristic of big data, development history of big data at home and abroad, and emphatically expounded the connotation of agricultural big data, development status of agricultural big data at home and abroad, as well as the applications of agricultural big data technology, agriculture big data resources and agricultural big data in various fields.展开更多

In the re-search, agricultural irrigation technologies at home and abroad were summarized in order to provide references for agricultural production.展开更多

Although the Chinese government has been actively promoting the agricultural water-saving technology adoption, it is ill-informed of the adoption degree of the current agricultural watersaving technologies as well as the function of the governmental policies, Therefore, this paper＂ analyzes the aforesaid problems based on investigative data of 10 provinces in China. The results demonstrate that although there is a rapid increase of adopted agricultural water-saving technologies, the actual adoption area is rather limited. Moreover, the governmental policies and scarcity of water resources are the deierminants of agricultural water-saving technology adoption. Ultimately, the paper proposes some policy suggestions.展开更多

A longitudinal multiple data collection technique employed involved various primary and secondary sources including site visits, literature review, observation, interviews with key personnel and group discussions. General findings of this study indicate： （1） the available coping mechanisms in smallholder farming in a climate change context and （2） the challenges faced in the actual delivery of water in terms of design, management, physical and institutional factors. The study provides pragmatic recommendations for overall improvement and performance in a local, technical and socio-economic context through evaluation of the current situation, practices and processes. An integrated approach to addressing climate change impacts should include water management, rehabilitation, complete overhaul and introduction of other relevant water systems and water saving farming techniques. Yet, ownership of these technologies by communities remains instrumental. Rural development and agricultural policies that ensure maximum and full capacity utilisation of water systems to improve rural livelihoods, mitigation and adaptation to climate change are recommended.展开更多

文摘Based on status quo of Chinese water resources, it is necessary to im-prove comprehensive agricultural productivity, establish water-saving, highly-efficient and pol ution-control modern agriculture, and to enhance irrigation efficiency and profits with the precondition of unchanged agricultural water amount. In the re-search, agricultural irrigation technologies at home and abroad were summarized in order to provide references for agricultural production.
