1437. Research Challenges for Stable Cacao Production
Cacao (Theobroma cacao L.), the raw material for chocolate, is native to South America and cultivated primarily on small farms in West Africa, Southeast Asia, and Latin America. It is an important cash crop for tropical countries in these regions. In recent years, poor cacao harvests in West Africa have caused international cacao prices to soar, reaching an all-time high in January 2025. However, by January 2026, the price had fallen by nearly half compared to the same month last year. This article introduces literature on challenges in cacao breeding and cultivation, as well as knowledge on pest and disease control. -

1436. Copernicus: 2026 Begins With Extreme Weather Events in Both Hemispheres, Was the Fifth-Warmest January on Record
According to the Copernicus Climate Change Service (C3S), January 2026 was the fifth-warmest month on record, while contrasting temperature extremes were recorded in the Northern and Southern Hemispheres, reminding us that climate systems can sometimes simultaneously bring extreme cold in some regions and extreme heat in others. -

1435. World Pulses Day 2026
Pulses offer exceptional nutritional value and immeasurable environmental benefits. However, the persistent perception of pulses as a "humble" or traditional food has contributed to declining consumption in many countries. The 2026 theme ("Pulses of the World: From Modesty to Excellence") aims to dispel these misconceptions and celebrate the true value of pulses, from their contributions to promoting human health to strengthening soil ecosystems. -

1434. January 2026 World Food Price Trends
The Food and Agriculture Organization of the United Nations (FAO) released its world food price trend report on February 6th. The average for January 2026 was 123.9 points, down 0.4% from the previous month. Declines in the price indexes for dairy products, meat, and sugar outweighed increases in the price indexes for cereals and vegetable oils, marking the fifth consecutive month of declines. The food index fell 0.6% from the same month last year and was 22.7% lower than its peak in March 2022. -

1432. Elucidating the Pathways of Change in Agricultural Greenhouse Gas Emissions
Discussions regarding the reduction of agricultural greenhouse gas (GHG) emissions have primarily focused on the "decoupling" pathway, which aims to reduce emissions while maintaining production growth. A paper published in Science Advances revealed that from 1961 to 2021, increases in total factor productivity (TFP) have consistently served as one of the primary drivers of GHG emissions reductions on farms, and that improvements in land productivity have also played a key role in reducing emissions intensity. -

1431. Who Will Train Researchers? (Takaragawa’s Newsletter Vol. 11)
I reflected on the role of academic societies and how researchers at national research institutes engage with them and contribute to talent development. The environment surrounding education and research in Japan now faces challenges that differ significantly from the era that once underpinned science and technology advancement, such as financial constraints and compliance requirements. I believe that JIRCAS, as a national research institution, may now be socially expected to adopt a more proactive stance. Rather than taking a passive approach of accepting talent educated at universities, it should actively collaborate with educational institutions to directly engage in human resource development. -

1430. JIRCAS Research Highlights Presented at Kaset Fair 2026, Kasetsart University, Thailand
Kaset Fair 2026, an agricultural exhibition, is being held at Kasetsart University in Thailand from January 30 to February 7, 2026. Kaset Fair, Thailand's largest agricultural and food trade fair, is hosted annually by Kasetsart University. During the event, the university campus is hosting a wide variety of exhibits, from research highlights related to the agriculture and food industry to sales of agricultural and food products, attracting many visitors. -

1428. The Role of Farms by Size in Transboundary Food Supply Chains
A paper published in Nature Food combined country-specific agricultural production patterns and agricultural trade data to assess the global contribution of farms of various sizes to national food consumption. The analysis found that in high-income countries, the role of smallholders in contributing to national food consumption was significantly underestimated, while in regions where smallholder agriculture is widespread, agricultural imports are sourced from countries and sectors dominated by large-scale agriculture. -

1427. The Need to Combat Overshoot
In 2015, 195 countries committed to limiting global warming to "well below 2°C" and "pursuing efforts to limit it to 1.5°C" in order to reduce human impacts on the climate system. While the United States has reportedly officially withdrawn from the Paris Agreement, a Nature commentary/opinion piece discusses the need for the world to confront "overshoot," or the loss and damage that would result if global warming were to exceed the 1.5°C limit, as well as the need for adaptation. -

A Nature Food article, based on an analysis by the IFPRI, considered six potential policy pathways for reducing greenhouse gas emissions, taking into account the unique characteristics of the agri-food sector. It found that green innovation, such as intermittent irrigation for rice and improved livestock feeding techniques, is the most promising and attractive pathway. -
