Future rice systems must produce more grain while minimizing the negative environmental impacts. A key question is how to orient agricultural research & development (R&D) programs at national to global scales to maximize the return on investment. Here we assess yield gap and resource-use efficiency (including water, pesticides, nitrogen, labor, energy, and associated global warming potential) across 32 rice cropping systems covering half of global rice harvested area. We show that achieving high yields and high resource-use efficiencies are not conflicting goals. Most cropping systems have room for increasing yield, resource-use efficiency, or both. In aggregate, current total rice production could be increased by 32%, and excess nitrogen almost eliminated, by focusing on a relatively small number of cropping systems with either large yield gaps or poor resource-use efficiencies. This study provides essential strategic insight on yield gap and resource-use efficiency for prioritizing national and global agricultural R&D investments to ensure adequate rice supply while minimizing negative environmental impact in coming decades.

Closing yield gaps for rice self-sufficiency in China

Haishun Yang

China produces 28% of global rice supply and is currently self-sufficient despite a massive rural-to-urban demographic transition that drives intense competition for land and water resources. At issue is whether it will remain self-sufficient, which depends on the potential to raise yields on existing rice land. Here we report a detailed spatial analysis of rice production potential in China and evaluate scenarios to 2030. We find that China is likely to remain self-sufficient in rice assuming current yield and consumption trajectories and no reduction in production area. A focus on increasing yields of double-rice systems on general, and in three single-rice provinces where yield gaps are relatively large, would provide greatest return on investments in research and development to remain self-sufficient. Discrepancies between results from our detailed bottom-up yield-gap analysis and those derived following a top-down methodology show that the two approaches would result in very different research and development priorities.

Can ratoon cropping improve resource use efficiencies and profitability of rice in central China?

Kenneth G. Cassman

• We collected farmer data from middle (MR), double (DR), and ratoon rice (RR) in China. • We assessed energy balance, carbon footprint, and economic benefit of MR, DR, and RR. • RR achieved higher annual grain yield, net energy yield, and net economic return than MR. • RR is an environment-friendly and economically viable alternative for both MR and DR.

Abscisic Acid Negatively Modulates Heat Tolerance in Rolled Leaf Rice by Increasing Leaf Temperature and Regulating Energy Homeostasis

Background: Abscisic acid (ABA) acts as a signaling hormone in plants against abiotic stress, but its function in energy homeostasis under heat stress is unclear. Results: Two rice genotypes, Nipponbare (wild-type, WT) with flat leaves and its mutant high temperature susceptibility (hts) plant with semi-rolled leaves, were subjected to heat stress. We found significantly higher tissue temperature, respiration rate, and ABA and H₂O₂ contents in leaves as well as a lower transpiration rate and stomatal conductance in hts than WT plants. Additionally, increased expression of HSP71.1 and HSP24.1 as well as greater increases in carbohydrate content, ATP, NAD (H), and dry matter weight, were detected in WT than hts plants under heat stress. More importantly, exogenous ABA significantly decreased heat tolerance of hts plants, but clearly enhanced heat resistance of WT plants. The increases in carbohydrates, ATP, NAD (H), and heat shock proteins in WT plants were enhanced by ABA under heat stress, whereas these increases were reduced in hts plants. Conclusion: It was concluded that ABA is a negative regulator of heat tolerance in hts plants with semi-rolled leaves by modulating energy homeostasis.

Intensifying rice production to reduce imports and land conversion in Africa

Africa produces around 60% of the rice the continent consumes, relying heavily on rice imports to fulfill the rest of the domestic demand. Over the past 10 years, the rice-agricultural area increased nearly 40%, while average yield remained stagnant. Here we used a process-based crop simulation modelling approach combined with local weather, soil, and management datasets to evaluate the potential to increase rice production on existing cropland area in Africa and assess cropland expansion and rice imports by year 2050 for different scenarios of yield intensification. We find that Africa can avoid further increases in rice imports, and even reduce them, through a combination of cropland expansion following the historical trend together with closure of the current exploitable yield gap by half or more. Without substantial increase in rice yields, meeting future rice demand will require larger rice imports and/or land conversion than now.

About Me

Prof. Shaobing Peng studied agriculture at Huazhong Agricultural College and received a bachelor’s degree in agriculture from 1979 to 1983. Then, he stayed at the school to teach. From 1985 to 1991, he received master’s and doctorate degrees and engaged in postdoctoral research at the University of California, Davis, Texas Tech University, and the University of Florida. Since October 1991, he has worked at the International Rice Research Institute in the Philippines as a senior crop physiologist. He returned to China in December 2010 and was employed as a full-time professor at Huazhong Agricultural University. Currently, he is the director of the Crop Physiology and Production Center (CPPC) of the College of Plant Science and Technology of Huazhong Agricultural University, deputy director of the State Key Laboratory of Crop Genetic Improvement, and director of the Key Laboratory of Crop Physiology, Ecology and Farming in the Middle Reaches of the Yangtze River of Agriculture. He engages in research in the fields of crop high-yield physiology and cultivation management, crop nutritional physiology and nutrient management, rice photosynthesis and water physiology, global climate change, and stress physiology. He has published more than 220 papers in some influential academic journals at home and abroad. He is on the editorial board of Field Crops Research, Plant Production Science, Journal of Integrative Agriculture, Chinese Agricultural Sciences, and Acta Crop Science.
