<jats:p>Non‐rainfall water inputs (<jats:styled-content style="fixed-case">NRWIs</jats:styled-content>) are the least studied hydrological components in most ecosystems. These <jats:styled-content style="fixed-case">NRWI</jats:styled-content> components potentially play an important role in ecosystem dynamics and are particularly important for water‐limited systems. In this review, we summarized recent advances investigating the effects of <jats:styled-content style="fixed-case">NRWIs</jats:styled-content> on various ecosystem functions, including vegetation‐water relations, biogeochemical cycling, groundwater recharge, as well as reptile and invertebrate adaptations. We also identified key knowledge gaps such as the mechanisms of <jats:styled-content style="fixed-case">NRWIs</jats:styled-content> alleviating vegetation water stress, sources of the <jats:styled-content style="fixed-case">NRWI</jats:styled-content> components and their quantitative contributions to ecosystem functions. To better predict the ecosystem responses to climate change especially in drylands, a better understanding and quantification of <jats:styled-content style="fixed-case">NRWI</jats:styled-content> contributions is essential. <jats:italic>WIREs Water</jats:italic> 2017, 4:e1179. doi: 10.1002/wat2.1179</jats:p><jats:p>This article is categorized under:
