Availability of observed climatic data is limited because of inadequate weather stations. Rainfall simulation models are important tools for simulation of rainfall in areas with limited or no observed data. Various weather generators have been developed that can produce time series of synthetic climate data. Verification of the applicability of the synthetic data is essential in order to determine their accuracy and reliability for use in areas different from those that were used during models development. The Marksim and Giovanni weather generators were compared against 10 years of observed data (1998-2007) for their performance in simulating rainfall in four stations within the northern bimodal areas of Tanzania. The observed and synthetic data were analyzed using climatic dialog of the INSTAT program. Results indicated that during the long rain season (masika) Giovanni predicted well the rainfall amounts, rainy days, and maximum dry spells compared to Marksim model. The Marksim model estimated seasonal lengths much better than the Giovanni model during masika. During short rain season (vuli), Giovanni was much better than Marksim. All the two models had better predictions during masika compared to vuli. The Giovanni model estimated probabilities of occurrence of rainfall much better (RMSE = 0.23, MAE = 0.18, and d =0.75) than Marksim (RMSE = 0.28, MAE = 0.23, R2 = 0.30 and d =0.63). The Marksim model over-predicted the probabilities of occurrence of dry spells greater than seven days (MBE = 0.17) compared to the Giovanni model (MBE = 0.01). In general the Giovanni model was more accurate than the Marksim model in most of the observed weather variables. The web based Giovanni model is best suited to the bimodal areas provided the web and remote sensing data representing the area are available. The Marksim model gives more accurate synthetic data if climate normals are used as input variables. Even without the climate normals the Marksim model can still be used to generate synthetic data in bimodal climatic areas where there are no observed data.Item Adaptation : Adaptation aux changements climatiques en Afrique (brochure)(CRDI, Ottawa, ON, CA, 2008) Centre de recherches pour le développement international (CRDI)Item Adaptation : Adaptation aux changements climatiques en Afrique; rapport annuel 2006-2007(CRDI, Ottawa, ON, CA, 2007) Centre de recherches pour le développement international (CRDI)Item Adaptation : Climate Change Adaptation in Africa (brochure)(IDRC, Ottawa, ON, CA, 2008) International Development Research Centre (IDRC)Item Adaptation : Climate Change Adaptation in Africa (CCAA) Research and Capacity Development Program; program strategy overview(2007) Kaeré, Alioune Badara; O'Neil, MaryThe document provides an overview of the programming strategy of the Climate Change Adaptation in Africa (CCAA) research and capacity development program. It describes: the vision, mission, goal, objectives, anticipated partners, priority themes and guiding principles; the program's expected outcomes related to the program objectives; the operational modalities, activities, program structure and work plan; and an outline of CCAA's monitoring and evaluation plan. Given the existing levels of greenhouse gasses in the atmosphere, African countries must adapt to the impacts of climate change.Item Adaptation : Climate Change Adaptation in Africa; annual report 2006-2007(IDRC, Ottawa, ON, CA, 2007) International Development Research Centre (IDRC)Item Adaptation : histoires vécues(CRDI, Ottawa, ON, CA, 2010) Denton, Fatima; Badara Kaéré, Alioune; Lo, Henri Matthieu; Thiao, Ibrahima Paul; CRDI; DFIDÀ propos du programme ACCA -- Le programme de recherche et de renforcement des capacités Adaptation aux changements climatiques en Afrique (ACCA) a été lancé en 2006 et est financé conjointement par le Centre de recherches pour le développement international (CRDI) du Canada et le Department for International Development (DFID) du Royaume-Uni. Il est hébergé et géré par le CRDI depuis son siège à Ottawa et trois bureaux régionaux en Afrique. Notre mandat initial prévoit cinq années d’activités de programmation, avec transfert graduel des responsabilités aux institutions africaines. Le financement initial fourni par le CRDI est de 15 millions CAD et celui du DFID de 24 millions GBP. Nous avons pour but de renforcer la capacité des pays d’Afrique à s’adapter aux changements climatiques au profit des communautés vulnérables. Le programme a pour objectif la création d’un bassin d’experts chevronnés et autonomes qui sauront répondre aux besoins définis par les collectivités, les décideurs et les institutions du continent africain.Item Adaptation : le programme Adaptation aux changements climatiques en Afrique (ACCA) par la recherche et le renforcement des capacités; aperçu de la stratégie(CRDI, Dakar, SN, 2007) Kaeré, Alioune Badara; O'Neil, MaryItem Adaptation : stories(IDRC, Ottawa, ON, CA, 2010) Denton, Fatima; Badara Kaéré, Alioune; Lo, Henri Matthieu; Thiao, Ibrahima Paul; IDRC; DFIDThis lovely book is a collection of stories of individual or community adaptations to climate change from various regions of the Sahel. Successful adaptation models come from the people who are living on the front lines, facing the many problems caused by climate change and climate variation. For instance, “An Experience in Perpetual Adaptation” recounts a story of nomadic herders where drought has made it impossible to follow their traditional long routes. Climate Change Adaptation in Africa (CCAA) works to establish a self-sustaining African body of expertise on adaptation that responds to needs defined by African communities, decisionmakers, and institutions.Item Adaptation Africa : CCAA news and events; February 2008(IDRC, Ottawa, ON, CA, 2008-02) International Development Research Centre (IDRC)This news and events bulletin is a quarterly publication providing ongoing listings for Climate Change Adaptation in Africa (CCAA), such as the CCAA at COP13 talks, project profiles of interest, conference announcements, networking, and program initiatives.Item Adaptation Africa : CCAA news and events; July 2007(IDRC, Ottawa, ON, CA, 2007-07) International Development Research Centre (IDRC)Item Adaptation Africa : CCAA news and events; June 2008(IDRC, Ottawa, ON, CA, 2008-06) International Development Research Centre (IDRC)Item Adaptation Africa : CCAA news and events; November 2007(IDRC, Ottawa, ON, CA, 2007-11) International Development Research Centre (IDRC)Item Adaptation Afrique : nouvelles et activités ACCA; février 2008(CRDI, Ottawa, ON, CA, 2008-02) Centre de recherches pour le développement international (CRDI)Item Adaptation Afrique : nouvelles et activités ACCA; juin 2008(CRDI, Ottawa, ON, CA, 2008-06) Centre de recherches pour le développement international (CRDI)Item Adaptation Afrique : nouvelles et activités ACCA; novembre 2007(CRDI, Ottawa, ON, CA, 2007-11) Centre de recherches pour le développement international (CRDI)
