The poorest and most vulnerable people tend to be the most affected by extreme weather events, even though they have the least to do with causing climate change. A World Bank study that discusses the relationship between climate change and global patterns of inequality.

According to the EU's Copernicus Climate Change Service, March 2025 was the second warmest March on record globally, with temperatures 1.60°C above pre-industrial levels. Arctic sea ice also recorded its lowest monthly March extent in 47 years of satellite records, standing 6% below average.

The paper "The futures of climate modeling" published in npj Climate and Atmospheric Science examines the current state of climate modeling and proposes future divergent paths for incremental change using various tools.

Changes in biodiversity pose significant threats to human societies at local and global scales, highlighting the urgent need to understand the impacts of anthropogenic activities on ecosystems. The paper published in Nature comprehensively analyzed published papers and quantified anthropogenic impacts on biodiversity across several spatial scales, from local to global, evaluating whether anthropogenically impacted sites are more similar to each other (homogenization) or different (differentiation) than reference sites, and examining changes in species composition.

How global warming will affect the global water cycle (the continuous movement of water between the Earth and the atmosphere) is also an important issue for water resource management and weather forecasting. A paper published in Science magazine presented evidence of a permanent decrease in terrestrial water storage under current climate change by integrating multiple global geophysical datasets. The evidence suggests that the decrease in soil moisture may be irreversible due to prolonged drought conditions and reduced precipitation in certain regions.

JIRCAS is a research organisation responsible for a series of research and development activities ranging from technological development to demonstration and social application in developing countries and other regions facing difficulties in the agriculture, forestry and fisheries industries. In each of these regions, production problems specific to each region arise, and it is necessary to find a way to solve these problems with flexible and innovative research ideas. Such ideas can actually be inspired by past practices at actual production sites. In this report, the importance of learning from historical documents, which contain a collection of local knowledge from the Edo era, is highlighted through a literature survey on sugarcane production in the Shikoku region.

In Africa, technical cooperation is being carried out in various fields, and while much of this has been successful in increasing the productivity and income of specific agricultural products, research has revealed that they have not necessarily increased total farm income and livelihoods. We decided to develop a new “farm management diagnostic tool” for Africa and tested it in Mozambique, resulting in successfully increasing the income of many farmers.

While nutrient-rich soil is best for plants, harmful bacteria might be lurking in the soil. That’s why it’s important to bring soil back to a lab, analyze it using various machines and chemicals, and find out its "health" and "personality." However, if you don’t have the right equipment, analyzing soil can be very difficult. That’s why I’ve been working on developing a simple soil analysis method that anyone can easily perform. Today, I’d like to share the story behind that development.

Conflicts and adverse weather conditions continue to cause food insecurity in many countries, and food price inflation has outpaced overall inflation in many countries, according to a World Bank blog.
