Africa confronts escalating internal migration and displacement crises fueled by intensifying climate hazards—particularly prolonged droughts—and persistent armed conflicts, which compound vulnerabilities across the continent. Previous research clearly links these stressors to heightened population movements, but limited empirical work examines climate adaptation's role, especially agriculture's influence, in moderating these effects at grid and country levels.
On this premise, a study led by Professor Hyun Kim, Associate Professor in the School of Public Administration at Chungnam National University, shows that while drought and armed conflict are strongly associated with increased migration, higher levels of adaptive capacity substantially reduce migration when these stressors are present. The article, which was made available online on November 25, 2025, in the journal Sustainable Development, analyzed country and grid-level data from African nations over a 20-year period (1995–2015).
Rather than serving as a standalone solution, climate adaptation acts as a moderating force. Countries with stronger adaptive capacity experience lower migration levels during drought or armed conflict than less adaptive countries. This capacity is measured through key indicators, including agricultural output, access to water, health systems, infrastructure, and disaster preparedness.
“Agricultural productivity plays a particularly important role,” said Dr. Hyun Kim. “Higher crop yields are consistently associated with lower migration, highlighting how food security and livelihoods help stabilize communities during climate and conflict-related shocks.”
The researchers examined migration data from the United Nations High Commissioner for Refugees, armed conflict records from the Uppsala Conflict Data Project, drought data from the EM-DAT disaster database, and climate adaptation indicators from the Notre Dame Global Adaptation Index. Migration was quantified by annual population movements originating within the countries, including internally displaced persons and asylum seekers.
The study finds that armed conflict and drought independently increase migration risk. However, their combined effects are significantly weakened in countries with stronger adaptive capacity. This moderating effect is most pronounced during crisis conditions, suggesting that climate adaptation policies are especially critical when communities face overlapping environmental and security threats.
“Climate adaptation is often framed as a long-term environmental strategy,” Prof. Kim said. “Our findings show it also has immediate social benefits by reducing migration pressures stemming from both climate hazards and armed conflict.”
Beyond migration outcomes, the results align closely with several United Nations Sustainable Development Goals (SDGs), including Good Health and Well-being (SDG 3), Reduced Inequalities (SDG 10), Climate Action (SDG 13), and Peace, Justice and Strong Institutions (SDG 16). Strengthening adaptive capacity, particularly within the agricultural sector, may help prevent humanitarian crises by addressing climate vulnerability before displacement escalates.
While the study focuses on Africa, the authors note that the findings hold broader implications for global debates on climate finance, climate justice, and migration governance. As climate risks intensify worldwide, the research underscores the importance of prioritizing adaptation as part of integrated strategies to reduce displacement and enhance resilience in vulnerable regions.

A research team led by Professor Yuan Li at Nanjing Medical University published a research paper entitled "A Cigarette Compound-Induced Tumor Microenvironment Promotes Sorafenib Resistance in Hepatocellular Carcinoma via the 14-3-3η-Modified Tumor-Associated Proteome" in the Chinese Medical Journal. This work provides valuable insights into the role of smoking in HCC progression and drug resistance, offering potential therapeutic targets for overcoming sorafenib resistance.
The study began with an analysis of clinical follow-up data from HCC patients, revealing that smokers exhibited significantly poorer ...
Neurodegenerative diseases such as Alzheimer’s, Parkinson’s, Huntington’s, and amyotrophic lateral sclerosis (ALS) affect millions of people worldwide, yet treatments remain largely limited to symptom management. A defining feature shared by these conditions is the buildup of misfolded proteins that damage neurons over time. Cells normally rely on a protein quality-control system to prevent this damage. At the center of this system are molecular chaperones or heat shock proteins, which help proteins fold correctly or direct misfolded proteins to degradation and helps maintain proteostasis. Among them, the Hsp70 family has attracted growing attention for ...
The vision of a fully connected world is rapidly becoming a reality through the Internet of Things (IoT)—a growing network of physical devices that collect and share data over the Internet, including everything from small sensors to autonomous vehicles and industrial equipment. To ensure this data is secure and not tampered with, engineers are increasingly turning to blockchain as a promising solution. While often associated with cryptocurrencies, blockchain is essentially a decentralized digital ledger; instead of one company controlling the data, it is shared and maintained collectively across a network of computers.
Unfortunately, ...
Chemotherapy commonly damages the intestinal lining, a well-known side effect. But this injury does not remain confined to the gut. It reshapes nutrient availability for intestinal bacteria, forcing the microbiota to adapt.
The researchers report that chemotherapy-induced damage to the intestinal lining alters nutrient availability for gut bacteria, reshaping the microbiota and increasing the production of indole-3-propionic acid (IPA), a tryptophan-derived microbial metabolite.
Rather than acting locally, IPA functions as a systemic messenger. It travels from the gut to the ...
Microorganisms live in biofilms - the equivalent of microbial “cities”- everywhere on Earth. These city-like structures protect and house microbial communities and play essential roles in enabling human and plant health on our planet. Now, a new Perspective article published in npj Biofilms and Microbiomes sets out a path to uncover the role of biofilms in health during long-duration spaceflight, and how spaceflight research can reshape our understanding of these microbial communities on Earth.

Organic matter carried in rivers to the Russian part of the Arctic Ocean may be creating more clouds and keeping the region cooler, a new study has found.
In a new paper published in Communications Earth & Environment, an international team of researchers, including atmospheric specialists from the University of Birmingham, examined an understudied region of the Arctic Circle which includes the Siberian region of Russia, to understand how aerosol formation, which is essential for cloud formation, was influenced by conditions in the region.
The researchers investigated the origins of Arctic clouds, finding that organic ...

Smartwatches with both PPG and ECG functionality improve the detection of atrial fibrillation in comparison with standard care. Researchers from Amsterdam UMC analysed the data from 437 patients and detected heart arrythmia four times more often in those who wore an Apple Watch. These results are published today in JACC (Journal of the American College of Cardiology).
"Traditionally, monitoring takes place with other ECG devices, but patients can find them a bit irritating, and most of them can only monitor for two weeks at a time,” says Michiel Winter, ...
