Drought Assessment Using SPEI and NDVI : Case of Lesotho
While drought conditions are generally a common and recurring phenomenon of the climate in Southern Africa especially Lesotho, the frequency of droughts in Lesotho has increased significantly over the past few years. Lesotho has suffered the devastating impacts of drought during the past several decades resulting in poor harvests and large livestock losses to rural farmers. The majority of the population in Lesotho engages with rain- fed agriculture and is dependent to some degree on own production for household food supply and/or cash income (Dejene, Midgley, & Marake, 2011). Any negative cha ...
Handbook of Drought Indicators and Indices
The purpose of this handbook is to cover some of the most commonly used drought indicators/indices that are being applied across drought-prone regions, with the goal of advancing monitoring, early warning and information delivery systems in support of risk-based drought management policies and preparedness plans. These concepts and indicators/indices are outlined below in what is considered to be a living document that will evolve and integrate new indicators and indices as they come to light and are applied in the future. The handbook is aimed at those who want to generate indicators and indi ...
Diagnosis Of Extreme Rainfall And Temperature Event Over Rwanda (1961-2010)
This study attempted to investigate the variability of extreme rainfall and temperature over Rwanda and the associated circulation anomalies forecasting on wet and dry rainfall events between 1961 and 2010. The datasets used to achieve the objectives includes Temperature, the rainfall dataset, wind vector, pressure vertical velocity (omega) and the Indian Ocean sea surface temperature (SST). The methods used include correlation analysis, Standardized anomaly, composite analysis, and Empirical Orthogonal Functions (EOF) analysis. The results show that the mean annual cycle depict two rainy Seas ...
The Sahel Drought Mechanism: insights from two contrasting extreme events
The Sahel drought mechanism: insights from two contrasting extreme events during boreal summer July-August-September (JAS) is investigated in this study using the standardized precipitation index (SPI). Empirical orthogonal function (EOF) and composite analyses were deployed in this study, where the global precipitation climatology center (GPCC) rainfall data is used. The SPI shows large widespread decreasing rainfall trend in the Sahel in the mid-1980s; thereafter, Sahel rainfall have recovered somewhat through the late 1990s, even though the drought conditions have not ended in the region. A ...
Projection of Future Streamflow Changes in the Pearl River Basin
Global climate change is remarkably changing the climatic patterns of the Pearl River basin and are significantly impacting the hydrological processes. Projection of future climate change impacts on steamflow variation is potential to provide scientific guidelines for sustainable water resources management and effective prevention and control for flood and drought disasters. In this study, a hydrological modeling system for assessing climate change impacts on runoffin the Pearl River basin was established and were used to simulate historical hydrological process and to project future streamflo ...
Spatial-temporal analysis and variability of meteorological drought during pre and south west monsoon period in Myanmar
The current study is an attempt to assess meteorological drought in Myanmar during the South west pre monsoon and monsoon period using observed rainfall data from 34 stations in Myanmar spanning from 1971 to 2010. The components of drought that were analyzed in this study were severity, persistence, frequency and probability of occurrence. Additional, trends in drought occurrence were analyzed using the Mann-Kendall (MK) method while the wavelet analysis was applied to PI value to identify various periodic processes.
