Short summary
Short summary
This study provides an empirical yet finely documented example highlighting a significant but often overlooked or misunderstood trade-off between land restoration strategies and groundwater sustainability in drylands at a global scale. It emphasizes that interventions to achieve climate change adaptation and land restoration goals may inadvertently compromise fragile water resources when hydrological feedbacks are not sufficiently considered.

In hydrological science, better accounting for regime shift (abrupt and/or irreversible changes) remains a challenge that could lead to a new paradigm for the adaptation to extreme events (flood , drought). In this article, we present a simple model that can account for a hydrological regime shift in Sahelian watersheds. Based on this model, we find that the Gorouol, Dargol, Nakanbé, and Sirba watersheds have shifted during the droughts of the '70s–'80s.

Short summary
Nature-based solutions (NBSs), such as green roofs, have appeared as relevant solutions to mitigate urban heat islands. The evapotranspiration (ET) process allows NBSs to cool the air. To improve our knowledge about ET assessment, this paper presents some experimental measurement campaigns carried out during three consecutive summers. Data are available for three different (large, small, and point-based) spatial scales.

Short summary
Long-term average water and energy cycles are described for two main land cover types in the cultivated Sahel (millet crop and fallow bush). Mean seasonal cycles and annual budgets for all component variables were estimated from detailed field and model analysis. Evapotranspiration totals over 80% of rainfall for both covers, but with different time distribution and soil/plant contributions. The remainder is shared between runoff and deep drainage for the crop, but is only runoff for the fallow.
