Drought and drought mitigation in Yobe State, Nigeria
Drought is regarded as a natural phenomenon and its impacts accumulate slowly over a long period. It is considered to be insufficient precipitation that leads to water scarcity, as triggered by meteorological parameters, such as temperature, precipitation and humidity. However, drought mitigation …

Goal Drought
<p><em>Goal Drought </em>is a collection of free verse and prose poetry that focuses on the sport of soccer. The collection explores the roles of fans and players within the sport as well as the strategy, concepts, and controversies that make up much of soccer. Beyond just the game, the collection …

Understanding drought propagation and its implications for drought management
Droughts have been recognized as one of the most complex natural disasters, especially because they involve interactions between numerous climatological, hydrological and human processes. During a drought event, deficits in precipitation gradually translate into deficits in soil moisture, …

Drought assessment and forecasting using a nonlinear aggregated drought index
This study developed an objective drought assessment tool through a Drought Index (DI), and then developed a drought forecasting tool using the developed DI to forecast future drought conditions. These tools can be used to assist water managers to assess droughts effectively and forecast future …

Propagation from meteorological drought to agricultural drought under climate change
… precipitation deficits, or meteorological droughts, often but not necessarily lead to persistent soil moisture deficits, also known as agricultural droughts. For the same amount of accumulated precipitation deficit, an agricultural drought may or may not be triggered depending on a number …

Characterization of palmer drought index as a precursor for drought mitigation
Coping with droughts involves two phases. In the first phase drought susceptibility of a region should be assessed for developing proper additional sources of supply which will be exploited during the course of a drought. The second phase focuses on the issuance of drought warnings and exercising …

Identification of Drought-Responsive Genes and Validation for Drought Resistance in Rice
Drought stress was studied in rice (Oryza sativa) and maize (Zea mays) to identify drought-responsive genes and associated biological processes. One experiment with rice examined drought responses in vegetative and reproductive tissues and identified drought-responsive genes in each tissue type. …

Cyprus drought water bank
… idea in the area. We propose that an emergency drought water bank encourages farmers to become part of the solution to the water problems on the island. The Cypriot government is currently turning to desalination of seawater to meet its water supply needs. This process offers a reliable but very …

Drought predictions: applications in Australia.
Drought is a global and recurrent natural phenomenon, the inevitable consequence of meteorological variability. This natural hazard brings about devastating effects because water is one of the most fundamental commodities for human survival, and a lack of water can result in varying consequences, …

Hydrological Drought - a Study across Europe
Aiming at a better understanding of drought causes and processes, the present study investigated hydrological drought characteristics in space and time and their large-scale atmospheric driving forces in Europe. On the basis of daily streamflow data of more than 600 European rivers for 1962-1990, …

Dissection of Drought Responses in Arabidopsis
… to many environmental stresses such as drought, and salinity. They have therefore evolved mechanisms to acclimate and tolerate environmental stresses. Knowledge of the molecular aspects of abiotic stress gleaned from extensive studies in Arabidopsis has provided much information on the …

Assessing Drought Flows For Yield Estimation
… the withdrawal is constrained by the worst drought flow in the river. There is no flexibility for operational adjustments other than implementing conservation measures. Where there is a storage reservoir, yields higher than the flow in the source stream can be maintained for a period of time …

Subalpine Forest Tree Seedling Response to Drought
<p>Knowledge of tree species’ ability to tolerate drought is necessary to anticipate future forest dynamics with climate change, especially at the seedling stage given their role in shaping forest structure. We used precipitation reduction shelters to mimic drought for subalpine conifer seedlings …

Systems Analysis of Plant Responses to Drought
… and RNA-sequencing to study their responses to drought stress. (2) Natural perturbations can be used to understand complex traits. In wild species, limited resources drive allocation strategies that balance trade-offs between survival risks and fitness benefits, which is central to their …
