[前沿资讯] UMD researcher highlights trends in consolidation of US agriculture with 35 years of data 进入全文
The current COVID-19 pandemic has more and more people asking about our food supply, how agriculture is moving forward, and where agriculture is going in this country. Based on the long term work of James MacDonald, a new research professor in Agricultural & Resource Economics at the University of Maryland, he is a firm believer in the Maya Angelou quote, "You can't really know where you are going until you know where you have been." In MacDonald's latest publication in Applied Economics Perspectives and Policies, he presents a detailed history of the consolidation of agriculture in the U.S. based on 35 years of data from the U.S. Census of Agriculture and surveys from the United States Department of Agriculture Economic Research Service (USDA-ERS), where MacDonald was employed for nearly four decades. As branch chief in the Structure, Technology, and Productivity Branch at USDA-ERS focused on agriculture, MacDonald was able to build out a program to analyze these trends in agriculture, characterizing the steady shift to fewer and larger farming operations across the country in all sectors of agriculture.

[学术文献] Smart Sustainable Farming Management Using Integrated Approach of IoT, Blockchain & Geospatial Technologies 进入全文
Advanced Intelligent Systems for Sustainable Development (AI2SD’2019)
Agriculture is now a trillion-dollar industry, making significant contributions to the growth of several developing as well as developed countries. The huge rise in the growing demand of food and making it sustainable for people is encouraging the need for smart farming. There is a great potential to transform traditional farming profoundly by integrating Internet of things (IoT), Blockchain, and Geospatial technologies to emerge as Smart Farming. Blockchain based farming provides farmers various instant agricultural data at one secured platform, represents a unique opportunity to bring greater efficiency, sustainable crop production, tackle food scarcity, and adds transparency and traceability to the exchange of data related to farming management. Uses of Blockchain in farming management is not only improving the food traceability but also making farming safer for farmers as well as consumers involved, less uncertain and more profitable to the farmers. This paper describes the use of Blockchain technology in farming to manage the practices in a smarter as well as sustainable way, by presenting the decentralized infrastructure with added immutable geospatial technology and IoT sensors capabilities. Our proposed system architecture will explain how Blockchain technology with GIS & IoT will revolutionize the traditional farming practices. Moreover, Blockchain preserves the stakeholders privacy by enhancing IoT framework with more reliable and secure data. Likewise, geospatial technologies create the greater impact by providing visualization and decision making through analytics by transforming traditional farming into sustainable farming.
Advanced Applications of Blockchain Technology
Blockchains play a vital role in FARMAR to track and trace the origin of food products in food supply chain. Supply Chain Management (SCM) is an essential business process in all spheres of the economy. SCM uses specific processes to connect from producer to consumer requirement through a chain. In a BCT(Blockchain Technology) based system, “records are immutable and trusted, eliminating the need for third parties to be involved. Potential farmer-facing impacts include ensuring that farmers receive timely and complete payments through the use of smart contracts and helping farmers to capture real-time data to more effectively manage their crops and harvests (source: nextbillion.net)”. Another benefit of using BCT in FARMAR is security where hacking or tampering the existing data is impossible by any intermediary. As an add-on to this process, IoT devices (Mobile phone-based Android app) are used to update the real-time quality and transit time of the product in FARMAR. It is integrated for improved traceability and usability of the products in the supply chain. The FARMAR aims to achieve these goals by developing a web application where FARMAR creates a value chain of integrity from farm to fork by using BCT.

In recent years, information technologies have attained remarkable advantages in promoting the development of sustainability in agriculture. However, challenges still exist in technology implementation, which mainly involves biased points of view, initially higher costs, uncertainty, lack of transparency, and trust. To tackle these challenges, recent research attempts to introduce blockchain technology, combined with ICT, to promote sustainable e-agriculture. Blockchain technology, due to its distributed network system, is believed to enable a more transparent supply chain and rebuild trust between members. Therefore, blockchain-enabled e-agriculture is widely considered as the next step towards sustainable agriculture. Realistically, implementing blockchain technology still offers some key issues, and a new perspective about sustainable data management systems is needed. In this paper, data demands from all related parties who care about sustainability achievements in the agricultural sector are taken into consideration. The paper proposes an overall system approach to insert blockchain technology into the current agri-food supply chain. It provides interesting insights about how to achieve sustainability, by creating a new value mechanism among blockchain network members.
