July 11 marked World Population Day. As of July 2026, the global population is estimated to have reached approximately 8.3 billion, and the long-term trend of population growth continues. However, a closer look at the data reveals that the world is entering a period of profound demographic transition.

The Copernicus Climate Change Service (C3S), Europe’s climate monitoring agency, has released its latest assessment of global temperature, oceanic, polar, and hydrological conditions for June 2026. According to the report, June 2026 was the second-warmest June ever recorded globally and the warmest June on record in Western Europe. In addition, sea surface temperatures reached a new June record, highlighting the continued accumulation of heat throughout the Earth's climate system.

The foods we consume every day are developed through a process that relies far more on experience and trial-and-error than many people realize. Creating new food products involves numerous stages—from ingredient selection and formulation design to fermentation, manufacturing, and sensory evaluation—each requiring significant experimentation, time, and resources. At the same time, global food systems are major contributors to greenhouse gas emissions and biodiversity loss, highlighting the urgent need for more sustainable approaches to food production. A recent review article published in Nature Food explores how artificial intelligence (AI) could serve as a powerful catalyst for transforming food development from an experience-driven practice into a predictive, design-oriented science.

The FAO Food Price Index (FFPI) averaged 130.3 points in June 2026, down 0.3 percent month-on-month. Higher vegetable oil and meat prices were more than offset by declines in sugar, cereals and dairy prices. Compared with historical levels, the index was 1.7 percent above its value a year earlier, but still 18.7 percent below the all-time high recorded in March 2022.

Cassava, the raw material for tapioca, is not cultivated from seeds, but rather by planting a portion of the stem in the soil. Because it does not require seeds, many currently cultivated cassava varieties do not flower, which poses a challenge in breeding. This time, we visited the Rayong Field Crop Research Center to observe efforts to address this challenge.

In recent years, anomalously high ocean temperatures—commonly referred to as marine heatwaves—have shown clear trends of expanding spatial extent, increasing intensity, and longer duration. These changes are already having significant impacts on marine ecosystems and the societies that depend on them. A recent study published in One Earth examines the record-breaking warm period from 2023 to 2024 and demonstrates that these impacts are occurring throughout the year rather than being confined to specific seasons.

June 29 is observed as the “International Day of the Tropics,” established by the United Nations.
Located in Ishigaki City, Okinawa Prefecture, the JIRCAS Tropical Agriculture Research Front (TARF) conducts advanced research leveraging its unique climatic and geographic characteristics, functioning as a frontline hub aimed at addressing global food and environmental challenges. Specifically, in addition to contributing technologies to developing regions, the center also supports domestic efforts such as breeding rice and sugarcane varieties, conserving and managing genetic resources of tropical crops, and developing varieties of beans, vegetables, tropical fruits, and forage crops suited to the southwestern islands—thereby contributing to the promotion of regional agriculture.
An open house at TARF is scheduled for Saturday, July 4, 2026. Those in the area are warmly encouraged to visit.
 

A study by Teber et al. (2026), published in Nature Communications, analyzed the relationship between human development and disaster impacts using more than 7,000 climate-related disasters recorded across 154 countries between 1990 and 2020. The study found that disaster impacts are associated not only with hazard intensity but also with regional socioeconomic conditions. Even under comparable hazard conditions, regions with lower levels of human development tended to experience greater human losses.

In June 2026, the Food and Agriculture Organization of the United Nations (FAO) released The State of World Fisheries and Aquaculture 2026. According to the report, global fisheries and aquaculture production reached a record 235 million tonnes in 2024. Aquaculture has become the primary driver of growth in aquatic animal production, accounting for 53 percent of total output. At the same time, the report highlights continuing challenges related to the sustainability of marine fishery resources and disparities in food availability across regions. In response, FAO emphasizes the importance of the Blue Transformation initiative to promote sustainable fisheries and aquaculture systems.
