    603. Technology Showcase for Asia and Africa

    Focusing on the results of collaborative research conducted by JIRCAS in recent years, we have compiled technologies that can contribute to the development of sustainable food systems, which are expected to be utilized in the Asia-Monsoon region and Sub-Saharan Africa. We hope that the technologies presented in this showcase will serve as a reference for a wide range of stakeholders and help to transform sustainable food systems.

    577. Year-round Alternate Wetting and Drying (AWD) Improves Farmers' Profits and Reduces Greenhouse Gas Emissions ― Promising mitigation and adaptation measures for climate change to be deployed in the Asia-Monsoon region―

    The Mekong Delta, located in southern Vietnam, is the country's largest paddy rice cropping region, with fertile lowlands and abundant rainfall. In recent years, the area planted with rice has been expanding, and measures to cope with greenhouse gas (GHG) emissions, including methane, and water demand are required. Using farmer survey data, JIRCAS evaluated the effects of year-round implementation of alternate wetting and drying (AWD) technology on farmers’ profits and GHG emissions reduction, and showed that it is an agricultural system with co-benefit that both increases farmers' profits and reduces environmental impacts from agriculture.

    568. International Day of the Tropics: Initiatives to Utilize Genetic Resources and the Island Environment of TARF

    June 29th is designated by the United Nations as the “International Day of the Tropics” to celebrate the extraordinary diversity and highlight the challenges of the tropics. The tropical regions account for 40% of the world's total surface area, approximately 80% of the world's biodiversity, and the majority of the world's diverse languages and cultures. The tropics have experienced significant economic development in recent years, but with the accompanying population growth and urbanization, coupled with climate change, the region faces challenges such as the degradation of the natural environment and ecosystems and a rapid decline in biodiversity. The rich natural environment and diverse biological resources of tropical regions need to be protected as common assets of the Earth.

    560. Desertification and Drought Day ー Rising up from drought together

    The World Day to Combat Desertification and Drought is held annually on June 17th to promote public awareness of international efforts to combat desertification. Desertification is the deterioration of land in arid areas, which occupy more than one-third of the world's land area and are home to nearly 40% of the world's population, primarily due to human activity and climate change. In fact, this desertification is not the expansion of existing deserts. Desertification is the decline in land productivity due to poverty and political instability, as well as excessive cultivation and grazing, improper irrigation and deforestation.

    557. Development of Enzyme-Free Microbial Saccharification Technology to Efficiently and Inexpensively Obtain Glucose from Biomass for the Production of Biofuels and Biochemicals

    A joint research group of JIRCAS and King Mongkut's University of Technology Thonburi (KMUTT) has been developing a saccharification technology to efficiently and inexpensively obtain glucose, which is necessary for the production of biofuels and biochemicals, from cellulose-based biomass, including stems, leaves, peels, and lees from harvesting and processing agricultural crops, and food residues, fiber and paper waste from everyday life. The newly developed “microbial saccharification” is a revolutionary technology that converts cellulose to glucose using only microbial culture, without the need for any enzyme addition, and is expected to be applied to materials such as waste cotton fiber that have not been recycled before, since it is expected to reduce costs.
