Climate and political effects on agriculture: Empirical evidence from SSA
International Studies of Economics, EarlyView.Abstract The most of Sub‐Saharan African (SSA) countries have been affected by climate change and food insecurity problems due to the reduction of production and productivity of cereal crops in the continent. The purpose of this research was to examine the short‐run and long‐run effects of climate change on agricultural productivity in 24 selected SSA ...

Continental hydrosystem modelling: the concept of nested stream–aquifer interfaces
, 2014 Coupled hydrological-hydrogeological models, emphasising the importance of the stream–aquifer interface, are more and more used in hydrological sciences for pluri-disciplinary studies aiming at investigating environmental is-sues.

Retardation of arsenic transport through a Pleistocene aquifer
Nature, 2013 Groundwater drawn daily from shallow alluvial sands by millions of wells over large areas of south and southeast Asia exposes an estimated population of over a hundred million people to toxic levels of arsenic.

Mixing in confined stratified aquifers
Journal of Contaminant Hydrology, 2011 Spatial variability in a flow field leads to spreading of a tracer plume. The effect of microdispersion is to smooth concentration gradients that exist in the system. The combined effect of these two phenomena leads to an 'effective' enhanced mixing that can be asymptotically quantified by an effective dispersion coefficient (i.e.

Modelling and optimisation of water management in sloping coastal aquifers with seepage, extraction and recharge [PDF]
arXiv, 2019 We consider the management of sloping, long and thin, coastal aquifers. We first develop a simple mathematical model, based on Darcy flow for porous media, which gives the water table height, and the flow velocity as a function of the underground seepage rate, the recharge rates and the extraction rates, neglecting sea water intrusion. We then validate

High quality InSAR data linked to seasonal change in hydraulic head for an agricultural area in the San Luis Valley, Colorado [PDF]
, 2011 In the San Luis Valley (SLV), Colorado legislation passed in 2004 requires that hydraulic head levels in the confined aquifer system stay within the range experienced in the years 1978–2000.
