IRRI in South Korea

Overview

Once heavily reliant on rice imports, South Korea has transformed into a rice self-sufficient country by cultivating high-yielding varieties and adopting innovative technologies during the Green Revolution. Its collaborations with IRRI began in the 1960s, laying the groundwork for the historic development of Tongil rice, a high-yielding and blast-resistant variety, which played a crucial role in self-sufficiency.

By 2024, the production of milled rice reached 3.5 million metric tons, reflecting a 3.2 percent decline from the previous year due to climatic pressures, as well as increased pests and diseases. Additionally, the area of land dedicated to rice cultivation decreased to 698,000 hectares (USDA, 2024). While rice continues to be a staple in the Korean diet, domestic consumption fell to nearly 4 million metric tons. However, the increasing popularity of manufactured rice products has partially mitigated this decline, indicating a shift in consumer preferences regarding rice consumption.

Currently, IRRI and South Korea are collaborating to breed high-quality and climate-smart Indica rice varieties that meet changing market demands. IRRI also partners with South Korea to enhance rice research networks across temperate regions, promoting knowledge exchange about production challenges and solutions, particularly for temperate or Japonica rice.

With the contributions of the Government of Korea, IRRI also extends the impact of rice research by disseminating relevant information, advancing agricultural technology transfer systems, and building local capacity to support innovation in the agro-industry in developing counties.

China and IRRI

Overview

China stands as the largest rice-producing country in the world and accounts for approximately 26% of the global rice production. According to FAO, it produced 208 million metric tons of paddy rice in 2023, with an average yield of 7.1 metric tons per hectare.

As China’s most important crop, rice is central to ensuring food security for the country’s growing 1.4 billion population. Yet, the effects of climate change, such as spring droughts, autumn flooding, and rising temperatures, continue to threaten its cultivation. Additionally, the diminishing arable land for rice farming, with about 29 million hectares, and soil degradation caused by heavy pesticide use pose further risks to its long-term productivity. At the same time, China’s diverse genetic resources remain largely untapped, offering valuable opportunities for developing improved rice varieties.

With over four decades of collaboration, IRRI served as a hub for building expertise in rice science for its scientists and students. This partnership has led to the widescale adoption of improved hybrid varieties, resulting in increased yields and reduced disease incidence, particularly rice blast disease. It has also generated new technologies that reduce pesticide use while enhancing productivity, bringing economic, social, and ecological benefits across the country.

Together, IRRI and China are working to develop adaptive solutions to climate change by breeding high-yielding and stress-resistant varieties and advancing rice farming technologies. IRRI also supports initiatives to strengthen cooperation, knowledge-sharing, and technological exchange among countries and institutions to drive sustainable rice production.
