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),

An integrated forest‐to‐market approach to promote lesser‐known timber species (LKTS) in a domestic timber market in the Congo Basin

PLANTS, PEOPLE, PLANET, EarlyView.
In the Congo Basin, domestic timber markets account for ~40% of timber consumption, yet demand is concentrated on a few high‐value species also sought after on international markets, raising concerns about their long‐term availability. We combine market, wood, and forest data to assess the potential of lesser‐known timber species (LKTS) to support a ...

Multi‐scale flow analysis for scale‐aware urban canopy models

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We found that scale‐aware models are necessary when numerical weather prediction models approach hectometric resolution, which is associated with a characteristic length‐scale of morphological heterogeneity. This morphology‐dependent length‐scale indicates that resolved and unresolved heterogeneity are equally important.
