Characterization of Coleus x hybridus Voss. 'Goldbound' water requirements
Plant water deficit is the major factor limiting global crop productivity. Yield loss caused by water stress is estimated to exceed total loss from all other causes. Moreover, availability of agricultural water is declining worldwide because of increasing demand and decreasing quality. …

Irrigation Water Requirements under Climate Change and Drought Events in Saskatchewan,
… models (GCMs) on irrigated agriculture and water supply in Saskatchewan using 27 different combinations of GCMs, special reports on emissions scenarios (SRES), and time periods (2020s, 2050s, 2080s). Future drought events are extracted from the scenarios using the Standardized …

Assessing maize water requirements in the context of climate change uncertainties over southern Africa
Climate change studies are subject to high uncertainties partly resulting from data reliability. This study investigates the challenges of using statistical downscaled climate data to examine the likely impacts of climate change on maize growth in southern Africa in the context of these …

Development of a land use-based spatial water requirements model for the Berg Water Management Area
This study was conducted to investigate the requirements for the spatial modelling of current and future water demand in the Berg River Water Management Area in the Western Cape of South Africa in order to produce a prototype model from which annual water requirements could be computed and …

Physiological studies of in vivo and in vitro water requirements and water relations of Chrysanthemum morifolium Ramat
… Ramat. showed a significant reduction in plant water status under both sunny and cloudy conditions in response to depriving them of water. Water potential, osmotic potential, and pressure potential proved appropriate parameters for indicating plant water status. Diurnal changes in water status …

Balancescapes: an investigation into the effectiveness of site-scale water harvesting in St. Louis, Missouri
… irrigation is a prodigious consumer of potable water and accounts for more than 50% of urban water use in the United States. It is therefore imperative to reserve potable water for essential uses. The variability of recent drought trends coupled with the prediction of more intense, less frequent …
