Traditional agricultural extension services intended to serve agro-pastoralists in Tanzania and Sub-Saharan Africa at large have failed to make significant impacts, due partly to the lack of knowledge-sharing practices to disseminate timely agricultural and livestock-keeping information. A key problem has been inadequate access to information due to weak linkages and interactions between agricultural and livestock research institutions; including, the lack of knowledge and information articulating best practices; and deficiency of relevant research information presented in easy to understand ways and localized to the needs of agro-pastoralists. However, in recent years, there has been growing attention devoted to the implementation of information and communication technologies (ICTs) in agriculture and livestock-keeping development. The growing ubiquity of mobile phones presents an excellent opportunity to put timely agricultural and livestock-keeping information into the hands of agro-pastoralists through direct linkages with the telecentres services in rural areas. The evidence has linked ICTs to an increase in gross domestic product; it has prompted dedication to the research of the socio-economic benefits and policy implications of ICTs consumption in Africa. Consisting of field case studies and implementation frameworks for telecentres, this paper provides a Tanzanian rural perspective and understanding of the developments in ICTs services for sustainable agro-pastoral livelihood. Therefore, the field results indicates that, the extent of the interaction between the telecentre services and agro-pastoralists in terms of ICTs access as a learning tool shows that more than half, 43.7% (178) and 23.6% (96) out of 407 respondents were interacting; whereby agro-pastoralists access the services provided by the telecentres to improve agro-pastoral livelihood. We conclude that the interaction between the telecentre services and agro-pastoralists has to be transformed; since the potential of ICTs services in rural areas as yet remains untapped and urgent measures are required to derive maximum benefits for sustainable agro-pastoral livelihood.

The unmatched world population growth with production has increased human demand causing starvation consequent to food shortage. Climate-smart agroforestry (CSAF) among other options can enhance productivity, improve income and food security, and stabilize the environment. This study investigates the land suitability for CSAF in the Bugesera and Rulindo regions of Rwanda. After searching the literature and the local expert knowledge and opinions, nine variables were considered for investigation in the study viz. elevation, slope, soil type, rainfall, temperature, LU/LC, distance from roads and trade centers, and landslide risks. The analysis used two commonly known techniques (AHP and GIS) integrated to classify and sort out the suitable land for CSAF practices and development. Results identified three CSAF suitability zones, ranging from 1,662.82ha (1.60%) as most suitable and 90,123.78ha (86.62%) suitable to 12,262.50ha (11.78%) unsuitable zones in Bugesera. In Rulindo, suitability zones range from 709.92ha (9.69%) as most suitable and 6,514.56ha (88.92%) suitable to 102.24ha (1.39%) unsuitable land for CSAF. Results further showed that the available means suitable land for CSAF are 34,683.03ha in Bugesera (34,683.03 ± 48,304.71) and 2,442.24ha in Rulindo (2,442.24 ± 3,539.79). Land suitability scores for CSAF largely varied across sites (F = 1.33, p = 0.31). Cross-validation using ground-truthing information (field visit and collection of GPS-based ground coordinates of random locations of actual CSAF) and evidence from literature about existing CSAF mostly supported the generated CSAF suitability maps (nearly 91% of ground-based locations supported the model output). These results reveal the extent of implementation of CSAF practices in the targeted areas. In areas such as Bugesera and Rulindo where investigations on CSAF are scanty, suitability maps in this study would allow identifying sites with high potential for CSAF. The cross-site suitability mapping and analysis for CSAF would provide an opportunity to policy-makers for location-specific land use planning for expanding and implementing CSAF-based models. Those would assist in addressing ecosystem restoration, optimum farm production, increased income, and enhanced food security. This study will pave the way for further studies on the potential CSAF and possibly required interventions for the assessed areas.

The study aimed to create a historical geographic information system (HGIS), including a geodatabase and simple web application for Dodoma Capital City (DCC) in Tanzania. A web GIS application based is an outcome of the study that can improves research on, and knowledge of, the rare artifacts of cultural and historical heritage in Dodoma Capital City (DCC) for historians and the wider academic community. Likewise, spatial data incorporated allows for visualization of the relationship between people, and their geographic and cultural surroundings. Therefore, the cultural geo-history in this paper describes the specific connection of the cultural artifacts and historical site in a given area to their environment and geographic space. For that purpose, the Dodoma Capital City (DCC) historical artifacts as a case study were cataloged based on GIS techniques, geocoding protocols, and describing the artifacts to create an intuitive and familiar tool for historical researchers and archivists to better understand the cultural geo-history of Dodoma Capital City (DCC). The resulting tool, the Dodoma Capital City Historical Geographical Information System (DCCHGIS), combines a geodatabase and a web application to provide access to a small portion of the geospatial cultural history of Dodoma Capital City (DCC). The DCCHGIS demonstrates that archiving are useful in creating an accurate, informative, and usable Historical Geographic Information System (HGIS) tool that increase the knowledge of and access to cultural geo-history.

The current fast growth of the city of Dodoma in central Tanzania threatens cultural heritage materials scattered on the landscape. However, natural processes such as weathering and erosion also add to this threat. Earlier, we reported on the existence of two cultural traditions on this landscape, the Middle Stone Age artefacts and the much younger Wambambali tradition based on pottery, grinding stones and remains of collapsed buildings. This paper presents qualitative data about the latter tradition from the perception of elders. Although our main focus was on the Wambambali tradition, elders broadened our scope and so we discuss the Wambambali on the wider perspective that includes succeeding communities, the Wagogo. Interview and focus group discussion techniques were used to collect data. The current whereabout of the Wambambali people is not known but there are two suggestions: The majority went south while a small group may have gone to the north. On the other hand, the Wagogo communities are formed by founders from different ethnic groups and regions and elders involved in our research predominantly trace their origins to the Hehe and Bena communities in today's Iringa/Njombe regions. The collective name for these incoming groups came to be known as Wagogo.
