Private R&D is a major source of innovation and productivity growth in agriculture worldwide. This paper examines trends and determinants of agricultural R&D in China. Results show that while the public sector monopolized agricultural research until recently, private agricultural R&D has grown rapidly since 2000, driven largely by agribusiness privatization. Public-sector R&D investments in bas...

This paper sets out to develop a framework for characterizing agricultural growth orientations. We identify four main components in the global food system (technology, institutions, people, and natural resources). Based on the extent to which any two of these components are important in driving the growth of agriculture, we distinguish four main orientations of agricultural growth: local food, ...

This paper focuses on the AGRIS Application Profile (AGRIS AP), a standard created specifically to enhance description, exchange and subsequent retrieval of agricultural Document-Like Information Objects (DLIOs). The AGRIS AP provides a minimum interoperability layer through which agricultural information can be described and exchanged. The standard, developed in light of the new AGRIS vision, ...
To effectively manage water resources in agricultural production, it is necessary to understand the spatiotemporal variation of the water footprint (WF) and the influences of agricultural inputs. Employing spatial autocorrelation analysis and a geographically weighted regression (GWR) model, we explored the spatial variations of the WF and their relationships with agricultural inputs from 1998 ...
China is at a critical stage of transformation from traditional to modern agriculture and its agriculture and rural economic sector faces severe challenges of shortage of natural resources, environmental degradation, agricultural disasters, sluggish income growth of farmers and widening disparity between urban and rural areas. The fundamental solution to these problems lies with the advancement...
In order to effectively implement sharing and integrated application of agricultural remote monitoring data, which is of distributed areas, various types, different systems and a large amount of data, across different areas, departments and systems, new networked framework is needed to be introduced to promote sharing of resources. In this paper, based on grid, considering the current situation...
With rapid development of computer science, the means of the agricultural park planning are renewed continuously. Based on the long-term practice in the agricultural park planning, we put forward innovatively the integrated information processing technology in three dimensions in the paper, that is, information, time and spatial dimensions, On the basis of the coupling relation of multi-dimensi...
