545. Heavy Rains, Storm Surges and Hurricanes
Along with climate change, the possibility of catastrophic disasters due to heavy rainfall as well as heat waves and droughts is predicted to increase. The Japan Meteorological Agency (JMA) and the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) have announced that they will change the way they communicate disaster prevention information, such as the threat of linear precipitation zones and storm surge warnings for inland areas. Across the ocean in the Atlantic, hurricanes are given alphabetical names, and Ida, which caused extensive damage last year, has been placed on the "retired" list. With the frequency and intensity of extreme weather events expected to increase under global warming, agriculture, forestry, and fisheries will be severely impacted and food security may be affected. Averting catastrophic events will require the development of early warning systems as well as the creation of resilient socioeconomic and food systems through both climate change mitigation and adaptation measures.

544. Impact of Simultaneous and Sequential Extreme Weather Events
The saying "Troubles never come singly" is becoming a reality when it comes to climate disasters in a warming world. A new NASA study, published in Environmental Research Letters, points to an increased probability of floods and heat waves occurring simultaneously in time and space, potentially resulting to crop failures, forest fires, and other disasters.

543. The Need for Proactive Management of Drought Risks
According to a report (DROUGHT IN NUMBERS 2022) published by the United Nations Convention to Combat Desertification (UNCCD) in May 2022, the increasing frequency and intensity of droughts in recent years are affecting not only human societies but the entire ecosystem on which all life depends. A proactive management approach to drought risk, rather than ad hoc response measures to crises, is required, and coordination and cooperation based on adequate financial measures and political will are needed to achieve this.

542. Symbiotic Microorganisms Contribute to the Promotion of Yam Growth― Aiming to Develop New Technology to Improve Productivity
Yam, a staple food and cash crop produced in West Africa, has been in increasing demand in recent years, and there is a need to improve its productivity. Recent studies have revealed that yams, like legume crops, symbiotically harbor nitrogen-fixing bacteria, which promote plant growth and tuber production. The results of these studies are expected to contribute to the development of yam varieties that can be cultivated in low-fertility soils, and fertilization technology that uses the power of microorganisms to reduce the cost of applying expensive chemical fertilizers.

541. Elucidating the Relationship Between Flowering Sex and Yield of White Guinea Yam― Towards the Development of Efficient Cultivation Methods―
White Guinea yam is widely grown in the West African coastal region (Guinea Savanna) and is an important crop that supports food supply and demand in this region. However, the labor-intensive cultivation of white Guinea yams is a major burden on farmers. In collaboration with the International Institute of Tropical Agriculture (IITA) in Nigeria, JIRCAS has now clarified the effect of flowering sex on tuber yield of white Guinea yam, which has not been well understood for a long time. This achievement reveals the possibility of yield improvement through flowering control in yams.

540. Climate Change, Food Crisis and the International Day for Biological Diversity
On May 18, the World Meteorological Organization (WMO) released the State of the Global Climate 2021, announcing that all four key indicators of climate change - greenhouse gas concentrations, sea level rise, ocean heat, and ocean acidification - reached new records in 2021. On the same day, UN Secretary-General Guterres also addressed the already critical global food crisis in climate change and COVID-19, sounding the alarm over the rapid deterioration of food security due to Russia's invasion of Ukraine and calling for urgent international collaboration to address the food crisis. May 22 is the International Day for Biological Diversity. In a globalized world, the issues of climate change, food crisis and biological diversity are closely interrelated and must be resolved through international collaboration.

539. Prospects and Potential of Amaranths and Underutilized Crops for Health Promotion
Global environmental change is one of the most serious threats to global food security. In addition, more than 2 billion people worldwide suffer from some form of micronutrient deficiency, known as ‘hidden hunger’. In this situation, over-dependence on a limited number of crop species, such as rice, wheat, maize, and soybean, can lead to loss of genetic diversity, vulnerability of crop breeding to environmental adaptation, and unbalanced nutrition. Effective utilization of underutilized crops and genetic resources, known as orphan crops, may be one of the solutions to these problems. We are pleased to present a review article on the potential of orphan crops, particularly amaranths, for addressing environmental and nutritional issues.

538. Genetic and Molecular Mechanisms Conferring Heat Stress Tolerance in Tomato
Climate change is a major threat to global food security, with the potential to affect the current food system not only by reducing crop production, but also by reducing the genetic diversity of its wild relatives, limiting options for future variety breeding and reducing the ability to adapt to more severe challenges in the future. In addition, the projected temperature rise in the future will increase the likelihood of extreme weather events, including heat waves, and heat stress will become a major contributor to abiotic stress in many crops. Heat stress can have adverse effects on plant morphology and physiology during all stages of vegetative and reproductive development. Especially in fruiting vegetables such as tomatoes, even moderate heat stress can dramatically reduce fruit set and yield, resulting in poor fruit quality. We are pleased to present a review article describing the genetic and molecular mechanisms for conferring heat stress tolerance in tomatoes.

532. Changes in Virulence of Asian Soybean Rust Pathogen in Bangladesh
Asian soybean rust is a serious problem in soybean production in tropical and subtropical regions. This disease is also a problem in Bangladesh along with the expansion of domestic production. In this study, we investigated the virulence of the Asian soybean rust against known resistance genes in order to control this disease through the introduction of resistant varieties. The results showed that while the virulence of the pathogenic samples in 2016 was weak and many of the known resistance genes were effective, the virulence of 2018 and 2019 samples changed strongly. They included a strongly virulent rust samples for which seven known resistance genes were completely ineffective. While the introduction of resistant varieties is effective from a cost and environmental impact perspective, the development of resistant varieties using gene-pyramiding to deal with highly virulent rusts is needed to achieve a stable effect of control.
