A team of international researchers, led by Associate Professor Masaki Eda of the Hokkaido University Museum, have discovered that the oldest type of poultry ever domesticated may have been geese. The study involved interdisciplinary research of bones excavated from Tianluoshan site in the lower Yangtze River valley, Zhejiang Province, China.

Endocrine-disrupting chemicals (EDCs), pharmaceuticals and personal care products (PPCPs) are extensively used in industrial and consumer applications. They are widely recognised as typical contaminants of emerging concern because of their environmentally persistent and bio-accumulative properties. Even in very low concentrations, they can disturb our hormonal balance, leading to reproductive impairment, abnormal development and growth retardation. Water and wastewater treatment systems worldwide face the challenge of effectively removing these contaminants.

The tourism industry’s performance was hampered first by the Easter Sunday bomb explosions in 2019 and then the COVID-19 pandemic. Sri Lanka saw a decline in tourist arrivals from 1,913,702 in 2019 to 194,495 in 2021. It is estimated that revenue declined from USD 3600 million to USD 261 million during 2019-2021, reflecting a staggering 92.75% reduction due to a fall in arrivals.

Despite enhanced trade partnerships in South Asia, intra-regional trade is far from reaching its theoretical potential. Similar production patterns and competitive sectors can be the causes. However, bilateral discussions to further lower trade costs continue. The ongoing Bangladesh-Sri Lanka discussions on a preferential trade agreement (PTA) will benefit from knowing the potential gains from reducing bilateral trade costs. In addition, knowledge of products with a higher potential for export gains will help optimise the economic benefits from a trade deal.

Sovereign debt restructuring can be pre-emptive or post-default. A default is inherently costly as it can result in a sustained loss of access to capital markets. That leaves pre-emptive restructuring when a country deems itself unable to service outstanding debt.

Surveys have revealed an upward trend in the number of brown bears over the past three decades in Hokkaido, Japan's northernmost island. Researchers at Hokkaido University have been investigating the causes and implications of the increase.

Unprecedented declines in merchandise trade, foreign direct investment (FDI) flows, tourism and cross-border migration have all been hallmarks of the economic fallout of COVID-19. As a result, growth expectations for countries worldwide dimmed. Nonetheless, thanks in part to substantial expansionary monetary and fiscal policies being rolled out to achieve pre-COVID economic recovery levels and the development of vaccines, the contraction in global trade and economic output are less than what was anticipated. The Sri Lankan economy too has been impacted by these external developments, witnessing fluctuating fortunes in its external sector performance. This blog discusses the impacts of global economic developments on Sri Lanka’s external sector and suggests ways to cushion them.

On 20 May 2021, Sri Lanka’s worst-ever marine disaster occurred when a fire erupted on the Singapore-registered MV X-Press Pearl container ship just 18 km Northwest of Colombo. While the long-term cost is yet to be determined, the negative impact on industries such as fisheries and tourism, and people who rely on the coastal resources of Sri Lanka is already apparent.

The nutritional status of children under five in Sri Lanka has not shown a significant improvement for the last 20 years. It has also been lagging behind most of the other health and social indicators on children. IPS research shows that household income, inadequate nutrient intake, breastfeeding practices, mothers’ education, etc., play a major role in child undernutrition in Sri Lanka. Moreover, given significant losses in household income experienced at the hands of the COVID-19 pandemic, nutrient intake may have declined further over the past year. As such, it would be a challenging task for health planners to develop effective strategies to minimise undernutrition among children under five years. This article highlights some of the facts contributing to child undernutrition in Sri Lanka and suggests ways to address this critical issue.

Our brain has no lymphatic system; however, it does have fluid flow, which is believed to play a role in removing waste from the brain. However, the fluid's point of origin and fluid flow is still unclear. The “multi-scale stable isotopes imaging” project in Hokkaido University aims to solve this mystery using advanced technology. “We would not have been able to perform this study without Hokkaido University’s MRI technology and the isotope microscope,” said the project’s PI, Professor Kohsuke Kudo of the Department of Radiology, Faculty of Medicine.

Living beings need elements to develop properly. The study of ionomics measures and analyses the element accumulations in living organisms to determine which mineral nutrients are required and not required for growth. Associate Professor Toshihiro Watanabe from Hokkaido University’s Research Faculty of Agriculture applies this approach to learn about mineral accumulation in both plants and soil, in addition to inter-element interactions.

“The earth is suffering from several ‘diseases’: global warming, ocean acidification, habitat loss, etc. If any of these diseases remains uncured, other diseases will accelerate and cause new ones to appear, hence putting humanity’s well-being in danger,” said Associate Professor Masahiko Fujii. For this reason, the research staff of the Faculty of Environmental Earth Science keeps on assessing the current global environmental issues and promoting renewable energy sources as a possible solution.

Susanne Klien is an associate professor at Hokkaido University’s Modern Japanese Studies Program (MJSP). Having explored intangible cultural heritage across Japan, Klien has been expanding her research in area studies and anthropology on rural Japan. During her previous work for a research institute in Tokyo, she observed a unique migration pattern that has been taking place in Japan: more young people are relocating from big cities to rural areas, for example to the Tohoku area, the northeastern portion of Japan’s main island of Honshu.
