​Connecting Rice Science and Production with Global Sustainability: A 5-Part Webinar Series

Rice is a staple for one-third of the world’s population. Given current concerns about climate change, water and land resource depletion, and the impact of food production on the environment, the dissemination of information on advancements in breeding and sustainable production of this major staple is crucial to the efforts at feeding the world’s growing population with minimal costs to the environment.

The increasingly delicate rice production ecosystems demand bridging sustainable production and processing practices for better end-use functionality of the commodity. This 5-part webinar series from the Rice Milling and Quality Technical Methods Committee will inform advancements in research, including water use for sustainable rice production, investigations of connections between the carbon and water cycles in rice production environments, advances in biotechnology for rice improvement, special development of rice varieties for different markets, and other topics that connect rice science and production with global sustainability.

Webinar Organizer and Moderator

Dr. Griffiths G. Atungulu is Associate Professor of Grain Processing & Post-harvest Systems' Engineering and the Interim Director of The University of Arkansas Rice Processing Program in the Food Science Department at the University Of Arkansas Division Of Agriculture.

    Webinar Overview

    Emerging advances in our understanding of plant genomes and in technological tools have created new opportunities to improve plant performance and food quality.  Specific traits and critical genetic markers can be selected more readily from existing plant materials. Likewise, the continued improvement of transgenic and gene-editing approaches have markedly changed how biotechnologists and plant breeders can alter traits and determine gene function. 

    In addition to the potential for changing food quality or agronomic traits in rice, these technologies also provide powerful tools to understand and ultimately manipulate plant physiology and development. We have pursued specific gene-edited alterations in enzymes thought to be important ​for longevity of brown rice storage. Lipase and lipoxygenase activities lead to oxidation of free fatty acids in the rice bran layer, and concurrent mutation might have a synergistic effect resulting in significant reduction of oxidative products in rice bran. These and other genes thought to contribute to grain quality and storage have been the targets of gene editing by our group and others.

    Consumer acceptance and global regulatory hurdles ultimately impact adoption of many biotech-developed cereals. The ever-changing climate of public perception and knowledge will continue to impact prospects for wider acceptance.​

    Webinar Overview​

    In response to changing production conditions and market forces, farmers continue to seek economically viable methods to produce more rice (Oryza sativa L.) grain with fewer inputs and smaller environmental footprints. To help address these issues, a historical review of irrigated cropland since 1954 to present will open the presentation.  A review of irrigation options for rice production will be described and include pros and cons of the following systems:  a continuous-flood delivered using cascade distribution, to two related levee-based systems (multiple-inlet rice flood distribution (MIRI) and MIRI plus alternate wetting-drying flood management (AWD)), zero-grade rice irrigation, and a non-levee furrow-irrigated system using end-blocking (ROW).  Finally, a look at opportunities for improved water management will highlight automation, in-field water level measurements, and formal initiatives for rice production.  An on-farm study that looked at irrigation management at the farm scale will be highlighted.

    Webinar Overview

    ​Over half of the rice produced in the United States is exported. As a region, Central America is our second largest market. It has been a top market for U.S. rice for many years, however, exports ha​ve fallen significantly over the past several years. The major driver behind this decline is grain quality, primarily grain appearance (chalk) and cooking quality (stickiness). To address these issues, the LSU AgCenter Rice Breeding Program has begun working to breed new rice varieties with the quality parameters desired by the Latin American market. The initial focus of this work has been to collaborate with members of U.S. and Latin American rice industries to create a consensus of the desired grain quality parameters for US rice being exported to Latin America. Upon defining these characteristics, suitable germplasm from the US and Latin America has been identified for use in the short- and long-term solutions. This webinar will highlight the plans of this project, present some of the findings thus far, and discuss future research and timelines. This work has been supported the USA Rice, a nonprofit trade association representing all segments of the U.S. rice industry.

    Webinar Overview

    Our research group works to test and develop climate-smart agricultural practices in U.S. rice production. Rice cultivation has a large water demand and is responsible for 8-10% of the world’s anthropogenic methane emissions. Conservation practices that aim to reduce water and decrease methane emissions are important in generating a climate-friendly food system. A water saving irrigation practice, known as alternate wetting and drying (AWD), introduces deliberate soil aerobic conditions that are known to reduce methane emissions. Our group uses micrometeorological techniques over the rice field landscape to better quantify these dynamics at the production scale. We have demonstrated a 60% reduction in CH4 emissions without harming harvest yield under AWD treatments compared to conventional irrigation treatments. Our research also includes the use of decision support tools that provide guidance to farmers to increase farm sustainability in order to compete in a market that increasingly demands sustainable products. These findings and others will be contextualized in a discussion about sustainability aspects of rice production in the U.S. Mid-South.

    Webinar Overview

    The global demand for staple crop products is expected to grow by 60% between 2010 and 2050 mainly as a result of increased population, per capita income growth and use of biofuels. This is also the case for rice, which provides 20% of the world’s food energy. Global demand for rice will continue to increase from 479 million tons in 2014/15 to 551 million tons in 2029/30. To meet this estimated future demand, agricultural production must be enhanced in an environmentally sustainable manner in the context of increasing competition for water, land and labor, as well as the constantly evolving threat from abiotic and biotic stresses, and under potentially more extreme weather conditions associated with climate change. Agriculture also needs to address problems of poor food and nutrition security for smallholder rice farmers, including women farmers. 

    This presentation reviews recent efforts to benchmark rice yield gaps and/or resource-use efficiency for wide range of rice systems that can serve to prioritize agricultural R&D investments at national level to global scales to increase rice production while reducing associated environmental impact.
