Response and resilience of karst subterranean estuary communities to precipitation impacts. [PDF]

Ecol Evol, 2023
Heavy precipitation events caused a halocline shift resulting in a mortality event at a karst subterranean estuary, affecting the fauna inhabiting under the halocline (dotted white line) at the marine groundwater layer (a‐b). Overall, marine species (c‐e) inhabiting the caves were impacted, and cave‐adapted fauna (f‐i) remain resilient to short‐term ...

Farm‐Scale Recharge Pits for Improving Local Groundwater Availability: Insights From a Hardrock Watershed in Rajasthan, India

World Water Policy, Volume 12, Issue 3, August 2026.
ABSTRACT Groundwater depletion is a major challenge in semiarid, hard‐rock regions where irrigation demands often exceed natural recharge. This study evaluates the effectiveness of farm‐scale recharge pits as a local, supplementary, and community‐managed groundwater recharge solution in the Dharta catchment of Rajasthan, India. Alongside check dams and
