Abstract： Rural revitalization is a major task in realizing the great rejuvenation of the Chinese nation. Agriculture is the foundation of rural areas, and developing smart agriculture is an important means to realize rural revitalization. The southern hilly and mountainous areas are the concentrated distribution areas of land desertification in China, with obvious disadvantages in agricultural infrastructure, large poverty areas, and deep poverty levels. They are the “hard bones” that are difficult to tackle in rural revitalization in China. In the important period of consolidating and expanding the achievements of poverty alleviation and continuously promoting rural revitalization, under the background of the vigorous development of high technologies such as the Internet of Things, artificial intelligence, and big data, the issues that urgently need to be thought about and solved include: how to realize informatization in the southern hills and mountains, how to find a reasonable path of modern agricultural and rural development, and how to drive rural peace and prosperity with agricultural development. Based on the basic status quo of population, cultivated land, and landforms in the southern hills and mountains, this study analyzes thoroughly the pain points that limit the development of agriculture in the southern hills and mountains. Focusing on the whole process of intelligent perception, intelligent communication, intelligent decision-making and intelligent operation of smart agriculture, it proposes ideas and steps for developing smart agriculture in the southern hills and mountains of China with the help of information and intelligent means. With the aim to form a set of smart agriculture development model to help rural revitalization in southern China, it will take Shuicheng County in Guizhou Province as an example to demonstrate before promoting it in an all-round way on a large scale. Finally, focusing on the shortcomings and challenges of the development of smart agriculture in the southern hills and mountains, four development suggestions are put forward.

Abstract： Food security is a top priority in national governance. Since 1949, high-standard farmland construction, agricultural mechanization development, and agricultural technology promotion have all contributed to the grain production. To ensure grain security, China has drawn a “red line” of 1.8 billion mu (about 120 million hectares) as the official minimum of arable land. At the same time, increasing the investment of capital goods such as fertilizer and pesticides can no longer produce more food. Due to the extensive farming method in the past, the continuous increase in total grain output becomes difficult in the future. With the rapid development of advanced technologies such as informatization, intelligence, Internet of Things, big data and artificial intelligence, fine management of agricultural production can be achieved. Through the integration of digital economy and traditional agricultural industries, developing smart agriculture will provide possibilities for increasing food production. Focusing on the three stages of grain production (including pre-, during- and after-production), this study puts forward the Nine-Step Approach of smart agriculture, namely two refinements, three changes, three reductions, and one use. For each step, the connotation, the existing technical bottleneck, and the potential of future improvement are discussed. In addition, suggestions for further development of smart agriculture are made from four perspectives, namely, data collection, data standardization, data applications, and data security.

Abstract： Poverty alleviation or mitigation through science and technology is one of the strategies implemented in China. Grassbased Livestock Husbandry aims to develop sustainable and profitable ruminant farming systems and is an attractive and effective countermeasure for poverty alleviation in grasslands of China. Our survey indicated that 152 counties in the grassland region are in poverty, representing 56.7% of the total 268 counties. Hence, grasslands are the regions where the “hard core” poverty populations reside. As a pilot initiative, Chinese Academy of Sciences has launched projects in the grasslands in the north and the moutain meadows in the south to couple forage cultivation and processing with husbandry of elite local livestock breeds by improving the efficiency of converters of feed to products, and the projects have substantially helped local people increase their household incomes. Nationwidely, the grassland occupies more than 40% of the total national land area, hence the sustainable development of grass-based livestock farming systems could play a central role and have great potential in poverty alleviation.

Abstract： China enters into a new era with high demand for nutritional and healthy food, and hence needs to adjust the agricultural production system to balance cereal production and livestock farming. Between the years 2010-2019 the production of red meat and milk has fallen far behind the consumption demand, resulting in sourcing and import of large quantity of red meat and milk products from the international market. In comparison to the average consumption levels in Asia and global, China’s consumption will continue to grow in the future, presenting a great challenge to the goals of 85% self-sufficiency rate for beef and mutton and more than 70% for milk. The farming-pastoral ecotone (FPE) of northern China covers 655 thousand km2 and plays an essential role in livestock farming and enviromental protection. How to implement Grass-based Livestock Husbandry and achieve high quality sustainable development of this region is discussed. Four suggestions are proposed, namely, to take a top-down approach and make a national plan the development of Grass-based Livestock Husbandry in the region; to introduce genome-based breeding of forage crops by molecular modules; to strengthen the innovation in forage product processing technologies to improve the usage efficiency of forage raw materials; and to integrate livestock farming into the rural revitalization initiative for the establishment of featured towns and villages dominated by livestock industries.

Abstract： With increasing awareness of balanced and healthy diet, the demand for ruminant products has been drastically increasing in China over the past decades. Grass-based Livestock Husbandry (GLiH), a new paradigm for agricultural restructuring and sustainable development, is highly encouraged to meet such demand. Yet, the country’s own production cannot self-support the demand, as envisaged by the soaring import of both red meats and forage products, albeit half of the nation’s cereal production is devoted to animal feed and forage crop production area amounts to 12 million ha. With the affluent population and limited arable land, China is facing challenge to explore possible land areas for GLiH development. We argue that one of the effective ways is to transform the lowand middle-yield fields, which account for over 70% of the cultivated lands, into forage crop production. Our analysis indicated that cultivation of forage crops could avoid the risks of low yield and low economic returns frequently occurring for cereal production on such lands. Furthermore, a forage-cereal rotation cropping system can significantly increase dry mass production, reduce the incidence of pest and disease damage, and ameliorate soil physical and chemical properties by improving soil organic matter, soil fertility and reducing salt and alkaline constraints. Three scenarios have been projected for the potential of the exploitation of low- and middleyielding land for livestock production, and the amount of the red meat production is estimated to be 17.98, 21.58, and 26.98 million tons, respectively, which are 1.6, 1.9, and 2.4 times of the current production nationwide. A case study for Shandong Province is further presented, demonstrating that exploring the saline-alkali land at the Yellow River Delta for forage crop production could substantially alleviate the shortage of forage supplies and optimize the agricultural infrastructure of the province.
