Introduction

A combined approach to assess groundwater resources depletion in data-scarce areas: a case study in Wadi Zabid, Yemen

“…inadequate in the face of worsening groundwater depletion (Nanni et al, 2006). Moreover, inadequate institutional and political arrangements have played a role in depletion (Nanni et al, 2006;Leal Filho and Sümer, 2015;Foster and Custodio, 2019).…”
