TL;DR: The surface hydrology of a semi-arid area of patterned vegetation in south-west Niger is described in this article, where four types of vegetation classes are recognized, each tending to occupy a constant position relative to the others and to the regional slope.

TL;DR: In this article, the effects of crust development, micro topography, rill distribution, and soil nutrients on crop yield variability within and between years (1994-1996) in a farmer's field in semi-arid Niger were investigated.

TL;DR: In this paper, an estimate of direct groundwater recharge below a region of natural woodland (tiger bush) has been made in south-west Niger using the solute profile technique, which has been collected from a 77 m deep well drug within the study area covered by HAPEX-Sahel (Hydrological and Atmospheric Pilot Experiment), an international large-scale energy, water and carbon balance experiment carried out during the summer of 1992.

TL;DR: In this paper, the importance of spatial redistribution of water in the dynamics and functioning of tiger bush bands is discussed, where the authors define the minimum common characteristics necessary for the existence of banded vegetation spatial structure, including a semiarid climate, high-intensity rainfall, and a gentle slope.

TL;DR: In this paper, the authors measured the spatial variability in infiltration and crop growth in a millet field at the southern supersite of the HAPEX-Sahel experiment in Niger.
