- Description: Abstract: Sustainable development goals (SDGs) 1 and 2 stand for ―No poverty‖ and ―Zero hunger‖ respectively. Achieving these goals cannot be separated from promoting sustainable agriculture and ensuring livelihoods, especially for rural communities. This study sought to determine the suitability of land for the cultivation of maize and sorghum crops in Vhembe District, South Africa. The study applied the Analytical Hierarchy Process (AHP) and the Weighted Linear Combination (WLC), multi-criteria decision-making techniques, for criteria weights calculations and suitability maps calculations respectively within a Geographic Information System (GIS) environment. Six criteria were used; Soil pH, Soil Structure, Rainfall, Maximum Temperature, Minimum Temperature and Elevation. A consistency ratio (CR) of 0.035 was obtained for maize criteria weights and 0.036 for sorghum criteria weights. The results revealed that only limited portions of the whole district is highly suitable for the cultivation of Maize with 15.01% and Sorghum with 19.39 of the land arable for farming. This suggests lower maize and sorghum crops yields in the district and the paper recommends more cultivation of other drought resistant crops other than maize and sorghum.

- Description: Abstract: Globally, integrated urban public transport has been used as a solution to improve public transport services and reduce private cars reliance which assist to reduce traffic congestion on the roads. In South Africa, Gauteng province, is challenged with traffic congestion on roads during certain peak hours daily. In Gauteng province, the government developed innovative urban public transport systems to improve the state of reliability and frequent movement of urban public transport which are the BRT system and the Gautrain system. However, there is still lack of reliability and seamless travelling. Therefore, this paper aims to explore locations where innovative urban public transport systems (BRT system and Gautrain system) can be integrated in the province. The study adopted qualitative research design that facilitated the gathering and analysis of spatial data and qualitative data from the innovative urban public transport officials, commuters and the GIS data (BRT and Gautrain shapefiles). Results revealed that there are numerous locations that can be integrated where commuters can switch from one urban public transport system to the next in order to improve travelling by public transport. The study concluded that this level of integration can create seamless travelling in the province and easy access to different modes of public transport. The study recommends that the identified locations need to receive attention as most commuters of these innovative UPT systems are located around these areas and the use of the created model in the study.

- Description: Abstract: Urban Public Transport (UPT) plays a very imperative role in a society, it allows people to access different locations easily. Good urban public transport services attract more users reducing private vehicle on the roads and creating an environment with less gas emission produced. Key instruments used globally for good public transport service are policies and legislative frameworks. In South Africa, all three spheres of government National, Provincial and Local have implemented good urban public transport systems. However, in all the three spheres of government, there seems to be lack of connectivity of different systems of innovative urban public transport (BRT system and Gautrain system). Therefore, this paper aims to identify policies and legislative frameworks put in place to integrate innovative urban public transport in Gauteng province and what strategies can be implemented from these documents. The study adopted qualitative research approach were literature of previous documented studies, urban public transport drafted policies and legislative framework documents in South Africa, and interviews conducted with urban public transport officials. The results revealed that there are policies and legislative frameworks implemented, however, it is difficult to practice the strategies and ideas documented as these systems are owned by different entities. The study concluded that the provincial government need to identify ways of strengthening the available policies and legislative frameworks to integrate the different innovative public transport systems, by doing so, a common ground could be identified for integration leading to convenient public transport creating seamless travelling in the province. The study recommends that policies and legislative frameworks used in developed countries with good integrated urban public transport should be adopted and practiced in Gauteng province.

- Description: Abstract: In contemporary literature there have been growing concerns regarding preservations of natural ecosystems. Given the global growth in awareness of global warming, the need for natural fire prediction models has grown rapidly. Using South Africa as a case study, we evaluate the potential of integrating several natural fire prediction models and geographical information system (GIS) platforms. Initially, natural fire prone regions in South Africa were spatially demarcated basing on municipal historical data records. Thereafter, the natural fire prediction models were applied/tested in parallel to identify the best prediction models that give optimum results in predicting natural fires. The models were assessed for accuracy using historical data. Preliminary results reveal locations in the North West, Mpumalanga and Limpopo province had the highest recorded potential for natural fires. In conclusion, the work demonstrates huge potential of prediction models in informing the likelihood of natural fire outbreaks. Lastly, the work recommends the adoption of natural fire prediction models and the subsequent formulation and use of relevant future natural fire mitigation policies and techniques to avert disasters in time.

- Description: Abstract: It has been more than twenty-five years since the World Bank published its comprehensive report on “Guidelines for Education and Training in Environmental Information Systems in Sub-Saharan Africa: Some Key Issues”. Since this report was published, there have been considerable improvements in the region on implementing many of the actions proposed in that report relating to education, training and technology transfer. This paper presents an update on some of the activities that have taken place since the report was published and provides details on the current situation in the region. The paper shows how organizations such as the African Association on Remote Sensing of Environment (AARSE), the International Society of Photogrammetry and Remote Sensing (ISPRS), the European Association of Remote Sensing Companies (EARSC), the Group on Earth Observation (GEO), as well as several others have helped to increase the manpower resources in the region and strengthened the institutional capacity in the field of Geoinformatics, by means of capacity building, technology transfer, international cooperation and through the provision of internal African resources. After reviewing what has happened in the field of Geo-Informatics education and training, we focused on current initiatives taken and challenges in five Sub-Saharan countries namely, Ethiopia, Nigeria, South Africa, Tanzania and Zimbabwe. We reviewed GIS education and training in the private sector, government, information communications technology in higher education institutions, GIS application areas and challenges facing GIS education and training. The paper concludes that, change should involve education stakeholders such as students, teachers/instructors in all level of education. Sub-Saharan Africa countries should focus on improving the quality of the curriculum, strengthening international and regional cooperation by the means of exchange programmes to improve education and training in Geoinformatics.

- Description: Abstract: In the age of smart cities and globalisation, smart mobility is not only a vital component in the physical functionality of cities but also an economic and social performance of the modern urban centres. Urban transformations that are taking place in South African cities exhibit a strong shift towards the adoption of smart cities concepts that entail smart governance, mobility, economy, living, environment and people; hence prioritizing the economy and the society’s needs. There have been massive innovative public transport systems developments in the City of Johannesburg since 2010, which are the rapid Gautrain, Gaubus and Rea Vaya bus as a way of complimenting the already existing Putco bus, Metro bus and Metro rail services. Paradoxically, the impact of such innovations particularly on socioeconomic development of the City of Johannesburg has not been highlighted conclusively in existing literature. Consequently, this paper seeks to explore and highlight socio-economic benefits of innovative public transportation systems in communities focusing on the City of Johannesburg. To comprehend this, the study used a mixed approach of qualitative, quantitative and spatial investigation. Questionnaires, key informant interviews, maps from ArcGIS software as well as crowd sourced data from Echo-Echo software were applied. This helped to reveal the socio-economic impact, developmental trends as well as perceptions of commuters using the innovative public transit systems. Research results revealed that innovative public transit systems contribute to socio-economic benefits however, a lot still needs to be done to improve their impacts on ordinary citizens and residents in the City of Johannesburg. Pursuant to that, the paper ends by recommending that there is need for strong linkages between innovative and sustainable public transportation development and socio-economic imperatives within communities and societies.
