Author:Davis, Claire L; Vincent, KDate:Oct 2017The handbook (Climate Risk and Vulnerability: A Handbook for Southern Africa) was conceived and designed with the intent to provide decision-makers with up-to-date information, appropriate for country planning, on the impacts and risks of ...Read more
Author:Badou, DF; Kapangaziwiri, Evison; Diekkrüger, B; Hounkpè, J; Afouda, ADate:Oct 2017West Africa experienced severe drought during the 1970s and 1980s, posing a threat to water resources. A wetter climate more recently suggests recovery from the drought. The Mann-Kendall trend and Theil-Sen’s slope estimator were applied to ...Read more
Author:Kgaphola, Motsoko J; Ramoelo, A; Odindi, J; Mwenge Kahinda, Jean-Marc; Seetal, Ashwin RDate:Oct 2021Interaction between biophysical variables and socioeconomic conditions are far more complex and affect land cover and quality. These are aggravated by global climate change and climate variability in semi-arid regions. Therefore, the study ...Read more
Author:Davis-Reddy, Claire LDate:Oct 2017The body of work on historical climate trends has been steadily increasing during the last decade. Global mean annual temperatures have increased by 0.85°C since 1880 and are projected to increase by 0.3 to 2.5 °C by 2050, relative to the ...Read more
Author:Malherbe, Johan; Engelbrecht, FA; Landman, WADate:Mar 2014Synoptic weather data and rainfall records are used to support previous suggestions that the decadal-scale cycle in certain climate records may be attributed to the modulation in tidal forcing related to the 18.6 year lunar nodal cycle. The ...Read more
Author:Beraki, Asmerom F; Landman, WADate:Sep 2013The interannual and decadal variability of the Southern Annual Mode (SAM) was examined in the ECHAM 4.5-MOM3-SA ocean-atmosphere coupled general circulation model (OAGCM). The analysis placed emphasis on the behavior of the SAM when its ...Read more
Author:Ojoyia, M; Mutanga, O; Mwenge Kahinda, Jean-Marc; Odindi, J; Abdel-Rahman, EMDate:Jan 2017Climate variability and change continue to be a threat to Africa’s agro-ecosystems. This is anticipated to have a multitude of immediate and long-term impacts on sub-Saharan Africa’s natural resources of the present study attempts to establish ...Read more
Author:Beraki, Asmerom F; Landman, WA; DeWitt, DDate:Sep 2012Southern Hemisphere (SH) climate variability has been the focus of several researchers (e.g., Wallace and Hsu, 1983). According to these early studies, the SH is characterized by quasistationary oscillations and zonally propagating waves in ...Read more
