    The Integrated Rapid Public Transport Network interventions in 13 cities in South Africa came about as a result of a forward thinking public transport strategy being presented by Government in 2007. Since then, costs of both implementation and operation have been shown to be higher than expected. The future budgeted capital funding required to roll out the proposed public transport investments are in excess of the level of grant funding likely to be available from the national fiscus. Third party funding options need to be actively investigated and developed to augment the capital investment allocations provided through the national fiscus. One such third party funding option is Public Private Partnerships in the development and operation of selected public transport infrastructure. This paper aims to reduce the mystique attached to Private Public Partnership (PPP) initiatives and seeks to link the use of PPP principles to the funding difficulties in IRPTNs. The paper concludes that PPP?s may well be a viable source of funding for selected elements or components of the IRPTNs. This will however require interventions at a National level in order to reduce the administrative burden on each of the 13 involved cities.Paper presented at the 34th Annual Southern African Transport Conference 6-9 July 2015 "Working Together to Deliver - Sakha Sonke", CSIR International Convention Centre, Pretoria, South Africa.The Minister of Transport, South AfricaTransportation Research Board of the US

    Paper presented at the 33rd Annual Southern African Transport Conference 7-10 July 2014 "Leading Transport into the Future", CSIR International Convention Centre, Pretoria, South Africa.The concept of compensating existing public transport operators for the detrimental impact of the roll-out of large-scale, publicly funded IPTNs on their businesses is valid. However, the general approach to compensation adopted by South Africa to date is not financially viable and has serious implications for future developments. Different compensation models that look to align operators’ success, financial and otherwise, with that of the new system they are incorporated into, must be considered and adopted going forward to ensure the sustainability of the country’s public transport transformation programme.This paper was transferred from the original CD ROM created for this conference.

    Paper presented at the 33rd Annual Southern African Transport Conference 7-10 July 2014 "Leading Transport into the Future", CSIR International Convention Centre, Pretoria, South Africa.The rollout of Integrated Rapid Public Transport Networks (IRPTNs) in 13 cities across South Africa has been a significant step forward in the provision of safe, affordable and reliable public transport services to the communities of our cities and towns. The incorporation of the existing minibus taxi operators into these systems has fundamentally changed the role of local government and the existing operators in the provision of public transport services and these changes have not come without their risks. This paper explores some of the risks experienced by the current approach to the design of our IRPTNs and suggests an alternative approach to the transformation of public transport services in South Africa. This alternative approach attempts to build on the capacity that already exists within the public transport sector whilst still being able to deliver regular, reliable and affordable transport services without some of the institutional and financial strains currently being experienced.This paper was transferred from the original CD ROM created for this conference.

    Towards a provincial public transport institutional framework for public and non-motorised transport transformation and improvement in the Western Cape

    Get PDF
    The Western Cape Government is currently developing a Provincial Public Transport Institutional Framework (PPTIF) to guide public and non-motorised transport improvement in the non-Metro areas of the Province. The framework aims to address the critical barriers to improving the current unacceptable state of affairs. The framework incorporates innovative approaches to tackling the challenges faced by the sector. Once the framework has been completed, it will be implemented. The PPTIF differs from the Provincial Land Transport Framework (PLTF). The primary reason for the PLTF is to serve as a strategic management tool for the provincial transport department and includes the vision, objectives and policies of the department; current public transport strategies and sector strategies as well as associated financial, monitoring and institutional arrangements. The PPTIF develops aspects of the PLTF in more detail, developing an institutional framework for achieving the improvement to public and non-motorised transport envisioned by the Department. The PPTIF also introduces innovative mechanisms for reducing cost and enhancing capacity to implement, which will inform future versions of the Provincial Land Transport Framework (PLTF).Paper presented at the 34th Annual Southern African Transport Conference 6-9 July 2015 "Working Together to Deliver - Sakha Sonke", CSIR International Convention Centre, Pretoria, South Africa.The Minister of Transport, South AfricaTransportation Research Board of the US

    Financing IRPTN operations : considerations for cities implementing I(R)PTNs in South Africa

    Get PDF
    The case for investment in road-based public transport in South Africa is provided in the Public Transport Strategy for South Africa (2007) and subsequent policy positions by the national Department of Transport (DOT). This gave rise to the Integrated (Rapid) Public Transport Networks (I(R)PTNs) to be implemented in then 12 (now 13) priority cities. To support this implementation, the national Department of Transport created a conditional grant to the priority municipalities, first called the Public Transport Infrastructure Fund (PTIF), then the Public Transport Infrastructure and Systems Grant (PTISG) and now the Public Transport Infrastructure Grant (PTIG) and the Public Transport Network Operations Grant (PTNOG). Planning, establishment and rollout of the I(R)PTNs in the 13 cities, over the seven years to 2014, has highlighted the real costs of these systems. There is an emerging recognition of the extent of the I(R)PTN operational costs. Initial expectations were that fare income from passengers would cover the operating costs (at least the direct operating costs) of the system. However, implementation in a number of cities to date has shown that the fare box is not sufficient to cover the direct operating costs of the I(R)PTNs, unless the fares in the new system are increased significantly above the current costs of existing public transport. Such an increase would not be economically feasible for passengers and consequently introduce unacceptable affordability issues and open the way for competition with the I(R)PTN. As a result, cities have to consider alternative avenues to finance the direct operating costs of their I(R)PTNs. Some income sources are directly related to the new transport system (including advertising on the I(R)PTNs and congestion charges), some are commercial revenue options, and some are funding options from Municipal resources (eg increases in the rates bill, equitable share, services income). This paper explores the range of income options available to cities and the potential contribution to offsetting the shortfall. Based on the evidence to date, the operational shortfalls of I(R)PTNs in South Africa are greater than anticipated and, despite the opportunities for additional funding explored here, it is likely that significant shortfalls will remain. This presents a financial risk for city treasuries with whom rests the ultimate responsibility for covering the I(R)PTN costs. A continued conversation about funding for I(R)PTNs is therefore urgently required.Paper presented at the 34th Annual Southern African Transport Conference 6-9 July 2015 "Working Together to Deliver - Sakha Sonke", CSIR International Convention Centre, Pretoria, South Africa.The Minister of Transport, South AfricaTransportation Research Board of the US

    IRPTN vehicle financing options and considerations

    Get PDF
    The roll-out of comprehensive public transport networks in our major cities is requiring considerable up-front investment by government. The acquisition of the bus fleet presents the second largest component of capital expenditure by the implementing municipalities. Various fleet financing models have been adopted including the use of national grant funding and debt. This paper sets out to describe the various financing models that have been used to date and highlight their implications with respect to various criteria including cost, risk and complexity. The paper then moves on to discuss the concern of municipal treasuries surrounding the potential consolidation of the buses onto the books of the municipalities and evaluates the effectiveness of the move to finance the buses ?off-balance sheet?. The rationale for the National Department of Transport?s (?NDOT?) preference for the use of Export Credit Agency financing (?ECAs?) as the financing route of choice is also discussed. The paper then addresses the outcomes of an on- versus off-balance sheet financing structure, and the implications on both the financing model and the underlying institutional structure. An alternate model is then introduced which proposes a hybrid between the debt financing options used thus far in an attempt to mitigate the short comings present in the existing models.Paper presented at the 34th Annual Southern African Transport Conference 6-9 July 2015 "Working Together to Deliver - Sakha Sonke", CSIR International Convention Centre, Pretoria, South Africa.The Minister of Transport, South AfricaTransportation Research Board of the US

    Urban eddy covariance measurements reveal significant missing NOx emissions in Central Europe

    Get PDF
    Nitrogen oxide (NOx) pollution is emerging as a primary environmental concern across Europe. While some large European metropolitan areas are already in breach of EU safety limits for NO2, this phenomenon does not seem to be only restricted to large industrialized areas anymore. Many smaller scale populated agglomerations including their surrounding rural areas are seeing frequent NO2 concentration violations. The question of a quantitative understanding of different NOx emission sources is therefore of immanent relevance for climate and air chemistry models as well as air pollution management and health. Here we report simultaneous eddy covariance flux measurements of NOx, CO2, CO and non methane volatile organic compound tracers in a city that might be considered representative for Central Europe and the greater Alpine region. Our data show that NOx fluxes are largely at variance with modelled emission projections, suggesting an appreciable underestimation of the traffic related atmospheric NOx input in Europe, comparable to the weekend-weekday effect, which locally changes ozone production rates by 40%

    Reviewing evidence of marine ecosystem change off South Africa

    Get PDF
    Recent changes have been observed in South African marine ecosystems. The main pressures on these ecosystems are fishing, climate change, pollution, ocean acidification and mining. The best long-term datasets are for trends in fishing pressures but there are many gaps, especially for non-commercial species. Fishing pressures have varied over time, depending on the species being caught. Little information exists for trends in other anthropogenic pressures. Field observations of environmental variables are limited in time and space. Remotely sensed satellite data have improved spatial and temporal coverage but the time-series are still too short to distinguish long-term trends from interannual and decadal variability. There are indications of recent cooling on the West and South coasts and warming on the East Coast over a period of 20 - 30 years. Oxygen concentrations on the West Coast have decreased over this period. Observed changes in offshore marine communities include southward and eastward changes in species distributions, changes in abundance of species, and probable alterations in foodweb dynamics. Causes of observed changes are difficult to attribute. Full understanding of marine ecosystem change requires ongoing and effective data collection, management and archiving, and coordination in carrying out ecosystem research.DHE

    Environmental DNA sequencing primers for eutardigrades and bdelloid rotifers

    <p>Abstract</p> <p>Background</p> <p>The time it takes to isolate individuals from environmental samples and then extract DNA from each individual is one of the problems with generating molecular data from meiofauna such as eutardigrades and bdelloid rotifers. The lack of consistent morphological information and the extreme abundance of these classes makes morphological identification of rare, or even common cryptic taxa a large and unwieldy task. This limits the ability to perform large-scale surveys of the diversity of these organisms.</p> <p>Here we demonstrate a culture-independent molecular survey approach that enables the generation of large amounts of eutardigrade and bdelloid rotifer sequence data directly from soil. Our PCR primers, specific to the 18s small-subunit rRNA gene, were developed for both eutardigrades and bdelloid rotifers.</p> <p>Results</p> <p>The developed primers successfully amplified DNA of their target organism from various soil DNA extracts. This was confirmed by both the BLAST similarity searches and phylogenetic analyses. Tardigrades showed much better phylogenetic resolution than bdelloids. Both groups of organisms exhibited varying levels of endemism.</p> <p>Conclusion</p> <p>The development of clade-specific primers for characterizing eutardigrades and bdelloid rotifers from environmental samples should greatly increase our ability to characterize the composition of these taxa in environmental samples. Environmental sequencing as shown here differs from other molecular survey methods in that there is no need to pre-isolate the organisms of interest from soil in order to amplify their DNA. The DNA sequences obtained from methods that do not require culturing can be identified post-hoc and placed phylogenetically as additional closely related sequences are obtained from morphologically identified conspecifics. Our non-cultured environmental sequence based approach will be able to provide a rapid and large-scale screening of the presence, absence and diversity of Bdelloidea and Eutardigrada in a variety of soils.</p
