Pick Up1545. 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. -
Pick Up1473. Meeting with IRRI to Strengthen Research Collaboration
On April 3, 2026, we welcomed Dr. Virender Kumar (Research Director), Dr. SAITO Kazuki (Senior Scientist), and Dr. IWANAGA Masa (Board Member) from the International Rice Research Institute (IRRI) for a courtesy visit and technical exchange. During the visit, we introduced our institutional framework and research projects, followed by broad discussions on strengthening future collaboration with IRRI. -
Pick Up1391. 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.

Pick Up1088. Ancient Wild Relatives Hold Key to Climate-Proofing Global Wheat Supply
https://www.cimmyt.org/news/ancient-wild-relatives-hold-key-to-climate-proofing-global-wheat-supply/Crop wild relatives that have survived changing climates for millions of years may provide the solution to adapting wheat, humanity's most widely grown crop, to climate change. Two new studies led by the International Maize and Wheat Improvement Center (CIMMYT) reveal how tapping into this ancient genetic diversity can revolutionize wheat breeding and safeguard global food security.
