Climate requirements for cultivated Liberica coffee (Coffea liberica) and consequences for its use and development as a crop species

PLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1890-1903, September 2026.
The global coffee industry, supporting 25 million smallholder farmers, is vulnerable to climate change. Diversifying the coffee species portfolio beyond Arabica and robusta is a promising intervention. Liberica coffee could provide adaptive capacity, although its climate parameters for cultivation are poorly known.

Waste, Value and Colonial Capitalism: The Historical Production of Climate Vulnerability in Sri Lanka's Dry Zone

The Geographical Journal, Volume 192, Issue 3, September 2026.
ABSTRACT Tracing the historical roots of climate vulnerability in Sri Lanka's dry zone, this paper contributes new insights into how the legacies of colonialism continue to shape who is vulnerable to climate change and why. Drawing on Gidwani's (2008) conceptualisation of colonial capitalism's waste/value dialectic, the analysis illustrates how ...

Limits of Symptom‐Based Inference in Fungal Plant Disease: Latency, Quiescence and Dormancy

Plant Pathology, Volume 75, Issue 5, September‐October 2026.
Symptomless fungal infections are not biologically uniform. Latency, quiescence and dormancy represent distinct biological states with different implications for interpreting infection, symptom development and epidemic emergence. Recognising these distinctions reduces reliance on symptom‐based inference in fungal plant disease. ABSTRACT In fungal plant
