Past, present and future of local crop evolution

PLANTS, PEOPLE, PLANET, EarlyView.
Promoting agrobiodiversity is a promising strategy for mitigating the negative effects of climate change on global food security. We highlight the central role evolutionary processes play in harnessing the potential of local crops by integrating genomics, archaeology, ethnobotany and traditional ecological knowledge (TEK).

Fonio (Digitaria exilis and Digitaria iburua) in Nigeria: Regional cultivation patterns, landrace diversity, and farmer knowledge for conserving a climate‐resilient indigenous cereal

PLANTS, PEOPLE, PLANET, EarlyView.
Fonio (Digitaria exilis and Digitaria iburua) cereals are valued for their drought resilience, adaptability to poor soils, and cultural importance. In Nigeria, where both species are cultivated, fonio has declined due to labor‐intensive processing, lower yields, and changing livelihood choices. By documenting 21 landraces (15 D. exilis and 6 D. iburua),

Carbonized polymer dots with aqueous‐stable room‐temperature phosphorescence: Mechanism, matrix engineering, and application

Responsive Materials, EarlyView.
This review focuses on inorganic and organic matrices that enable aqueous‐stable room‐temperature phosphorescence (RTP) in carbonized polymer dots (CPDs). It explains the underlying RTP mechanisms, highlights how matrix engineering provides spatial confinement and bonding interactions to stabilize triplet excitons in water, and demonstrates key ...

Operationalising Circular Economy Through Social Innovation: A Systems Thinking‐Based Model for Sustainability Transitions

Sustainable Development, EarlyView.
ABSTRACT Social innovation (SI) is increasingly recognised as an important enabler of circular economy (CE) transitions. However, existing research offers limited explanation of the processes through which SI operationalises CE principles, as SI and CE have largely evolved in parallel and existing conceptualisations remain predominantly descriptive ...

Sequential Reduction of Chromite Pellets Using Hydrogen and Silicon Carbide for Carbon Emission Abatement During Ferrochrome Production

steel research international, EarlyView.
H2 prereduction selectively metallizes Fe in UG2 chromite pellets at 1100°C, while silicon carbide becomes active at 1300°C to convert remaining Cr2O3 to carbides and promote Cr metallization. By separating the roles of H2 and SiC, the sequential route reaches up to 65.7% Cr metallization and suppresses in‐furnace CO generation by ≈75% versus ...

Advances in Unconventional and Sustainable Synthetic Approaches to Benzopyran Scaffolds

The Chemical Record, EarlyView.
This review provides a comprehensive and critical analysis of low‐impact synthetic methodologies reported in the last 8 years (2018–2026) for the construction of benzopyran‐derived scaffolds, such as coumarins, flavones, chromones, chromenes, and chromanes. The benzopyran scaffold is a versatile family of heterocycles found in a wide range of bioactive

Economic Analysis of Infrastructure Investment and Break‐Even Carbon Prices for Low‐Water, Low‐Emission Farming Techniques in Vietnam

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT Excessive water use in rice production is a major source of methane emissions, the dominant greenhouse gas from Vietnam's agricultural sector. Improving water‐use efficiency can enhance water security and reduce emissions, but achieving these gains requires substantial changes in farming practices and significant investment in supporting ...

Uses Of Lime -Rice Husk Ash And Plastic Fibers As Mixtures-Material In High-Plasticity Clayey Subgrade: A Preliminary Study

Semesta Teknika, 2016
Silica produced from rice husk ashes have investigated successfully as a pozzolanic material in soil stabilization. However, rice husk ash cannot be used solely since the materials lack in calcium element.

The Late Agricultural Development of Central Arabian Oases—Archaeobotanical and Archaeozoological Studies of the al‐Kharj Oasis

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT While oasis settlements emerged during the Bronze Age in Eastern and Northern Arabia, the settlement process in Central Arabia was different. Excavations at al‐Yamāma—main ancient settlement of the al‐Kharj oasis (Riyadh Province, KSA)—suggest that the latter did not emerge before the second half of the first millennium BCE.
