    1571. IRRI: Supporting Rice Research Worldwide—Working with Japan to Address Rice Production under Climate Change

    Rice, an essential part of the Japanese diet, is not immune to the effects of climate change. Rice production worldwide must simultaneously address multiple challenges, including high temperatures, water scarcity, pests and diseases, and the need to reduce environmental impacts and greenhouse gas emissions. One institution that has long tackled these issues internationally is the International Rice Research Institute (IRRI), headquartered in the Philippines. Japan and IRRI have worked together for more than 60 years through rice research and exchanges among researchers.

    In October 2026, IRRI, the Japan International Research Center for Agricultural Sciences (JIRCAS), and the National Agriculture and Food Research Organization (NARO) will jointly hold the International Strategy Forum and Technical Workshop on Heat-Resilient Rice Production Systems in Tokyo. This article introduces IRRI’s role and the history of its cooperation with Japan, while considering the research partnerships that will be important for rice production under a changing climate.

    1570. Protecting Rice from Heat: Understanding Heat-Induced Sterility and Building Heat-Resilient Rice Production Systems

    Japan’s annual mean temperature has risen over the long term, and the Japan Meteorological Agency reports that unusually warm years have occurred frequently since the 1990s. How do rising temperatures and heat waves associated with climate change affect rice yield and quality? This article explains how heat-induced sterility occurs and why it is important to combine heat-tolerant varieties, crop management, climate-impact assessment, and future projections. On October 13 and 14, the International Rice Research Institute (IRRI), JIRCAS, and the National Agriculture and Food Research Organization (NARO) will jointly hold an international forum and technical workshop to discuss research priorities and directions for international collaboration toward heat-resilient rice production systems.

    1545. The Future of Sustainable Mangrove Management on the International Day of Mangroves — New Opportunities for International Collaboration Emerging from MMM7 and the JIRCAS Workshop

    Every year on July 26, UNESCO observes the International Day for the Conservation of the Mangrove Ecosystem. The day serves as an opportunity to raise awareness of the value of mangrove ecosystems, which play vital roles in climate change mitigation, biodiversity conservation, coastal protection, and the sustainable development of local communities. This article highlights discussions from the 7th Mangrove Macrobenthos and Management Conference (MMM7) and a workshop organized by the Japan International Research Center for Agricultural Sciences (JIRCAS), exploring future prospects for international collaboration toward sustainable mangrove management.

    1391. Carbon is a Wonderful Partner for Nitrogen in Protecting the Earth

    Now that we can use more fertilizer, we no longer have to worry about food. But it's not all good. If too much fertilizer is added to fields, the reactive nitrogen that plants don't use can pollute rivers and the air, causing various environmental problems. This is becoming more common, so we need to take action quickly. We will introduce a study that investigates whether adding charcoal to soil can keep the nitrogen in fertilizer in the soil for longer, allowing nitrogen to be used without waste.
