World Water Policy, Volume 12, Issue 3, August 2026.ABSTRACT In Ghana, the government has initiated a reform in rural water management to shift away from community‐based management (CBM) to state management, but research assessing the reform is still insufficient. This study aims to critically evaluate the impact of the reform in addressing rural water challenges.

Assessing differences among elasmobranch nurseries to aid conservation based on a genomics framework
Conservation Biology, Volume 40, Issue 4, August 2026.Abstract Elasmobranch nurseries often differ in environmental conditions, demographics, and use patterns. These differences affect the distribution of genetic variation among nurseries. However, conservation and management strategies often fail to account for such differences because they are difficult to characterize.

Exploring legal‐ and health‐risk messaging to reduce demand for elephant skin
Conservation Biology, Volume 40, Issue 4, August 2026.Abstract Asian elephants (Elephas maximus) are poached for an illegal trade in their skins, which are used in traditional medicine in Africa and Asia. We explored whether messages about the legal and health risks of using elephant skin for medicinal purposes (stomach illness) could reduce such consumption.
