Twenty-five rice research priorities for sustainable rice systems by 2050

Abstract

Abstract Non-technical Summary Agricultural research is vital for sustainable food production, amid changing challenges. To address these challenges effectively and achieve sustainable food systems, researchers and funding bodies have to prioritize research efforts. We conducted horizon scanning to determine how rice systems might change by 2050 and to identify key research gaps. The study involved 101 rice experts from 31 countries who rated the research gaps based on novelty and relevance. The top 25 research gaps encompass sustainability, agricultural development, rice crop science (including genetics, breeding, and physiology), and policies. Addressing these research gaps will contribute toward the sustainability of rice systems. Technical Summary Agricultural research and development (AgR&D) is crucial for increasing productivity while preserving natural capital and ensuring sustainable food security. Traditional AgR&D approaches along monodisciplinary lines often have unintended consequences and trade-offs, which can be avoided through integrated and interdisciplinary approaches. One such approach is horizon scanning. We conducted a horizon-scanning activity to identify research gaps to be prioritized for sustainable rice systems by 2050. The horizon scan involved a global and diverse panel of rice experts (101 from 31 countries). The panel responded to questionnaires on the drivers, projections, and research needs for rice AgR&D. Afterward, research gaps were rated on their relevance and novelty to sustainable rice systems. We identified the top 25 research gaps under four themes: sustainability interactions, agricultural development, genetics, breeding and crop physiology, and governance and policies. These gaps highlight research that needs to be prioritized to achieve sustainable rice systems that enhance resilience, conserve biodiversity, and promote socio-economic well-being. Social media summary Rice experts select top rice research gaps for achieving sustainable rice systems by 2050.
