Suitability of slightly saline irrigation for alleviating drought stress in taro and yam in Tonga: Implications for climate‐resilient Pacific cropping systems

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
There is an increasing risk of drought and salinisation of soil and groundwater globally, including in Pacific Island countries such as Tonga. Irrigating crops with slightly saline water, such as that produced by emerging desalination technologies, could help to alleviate droughts.

A national crop wild relative checklist for Zimbabwe reveals edible crop wild relative diversity of regional and global importance

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Crop wild relatives (CWR) in Zimbabwe are reservoirs of beneficial agronomic traits, yet they remain under‐documented and poorly conserved. This study developed Zimbabwe's first national CWR checklist based on a conceptual framework combining floristic, ecological and ethnobotanical data, revealing over 2700 taxa, with nearly 1000 edible species ...
