Abstract In any basin or basin country, water security is of critical importance. The increase in populations and water demand are placing stress on the available water resources. This is likely to become more complicated within shared water-courses. Issues of equitable water allocation and distribution are important for all countries involved. Fostering cooperation and managing conflict hence become fundamental in transboundary water management. Climate change is likely to add new challenges to pre-existing dynamics in transboundary systems. According to the Southern African Development Community (SADC) Climate Change Strategy and the SADC Shared Watercourses Protocol, there is a need to integrate climate change impacts and associated adaptation measures into water management plans to ensure water security for all countries involved in the future. The Orange-Senqu basin, which spans over Lesotho, South Africa, Namibia and Botswana, will be used as a case study to closely examine and reflect on some hydro-political challenges that may be brought about by climate change-associated impacts within the basin states. Although uncertain, climate projections largely indicate decline in rainfall and increase in temperature, especially within the South Africa part of the basin. This inherently is bound to affect water quantity and, therefore, availability within the riparian states below South Africa.

Since the impacts of climate change will last for many years, adaptation to this phenomenon should be prioritized in urban management plans. Although Tehran, the capital of Iran, has been subject to a variety of climate change impacts in recent years, appropriate adaptation measures to address them are yet to be taken. This study primarily aims to categorize the barriers to climate change adaptation in Tehran and analyze the way they interact with each other. The study was done in three steps: first, the focus group discussion (FGD) method was used to identify the barriers; next, the survey and the structural equation modeling (SEM) were used to validate the barriers, identify their importance, and examine their possible inter-relationships; and finally, the interpretive structural modeling (ISM) was applied to categorize and visualize the relationships between the barriers. Results show that barriers related to the ‘structure and culture of research’, ‘laws and regulations’, and ‘planning’ belong to the cluster of independent barriers and are of greater significance. The ‘social’ barrier and barriers related to ‘resources and resource management’ are identified as dependent barriers and are of lesser importance. Barriers related to ‘governance’, ‘awareness’, ‘education and knowledge’, ‘communication and interaction’, and ‘economy’ are identified at the intermediate cluster. The findings of this study can provide planners and decision makers with invaluable insights as to how to develop strategies for climate change adaptation in Tehran. Despite the scope of the study being confined to Tehran, its implications go far beyond this metropolis.

Abstract Many countries in the world, including South Africa, are water-stressed with increasing pressure on their water resources due to population growth, climate change, and inadequate funding. Post independence in 1994, many policies and programmes were introduced by the government with the aim of promoting water management. While these policies and strategies achieved much in terms of water provision to communities and households, they failed to establish a water-conscious country with sufficient knowledge and expertise in water management. In addition, these policies and programmes are outdated, compartmentalised, complex, and lack robust water governance with resilient stakeholder partnerships that advance the more explicit second phase of the NDP to achieve water security under the threat of climate change. Using data collection tools inspired by the traditional method of participatory research, this paper analyses the structural and systematic factors hindering the implementation of comprehensive policies to achieve water security in South Africa. There is, therefore, an urgent need for South Africa to establish an independent water regulator to ensure coordination between different government departments, including the National Treasury, to strengthen weak governance capacity and to make it independent to attract private equity into the sector and to recover fiscal deficits in the water sector.

This study explored the implications of climate change for rural transport in South Africa. The article was seeking to convert existing rural transport adaptation constraints into rural transport adaptation opportunities. Challenges and constraints to rural transport adaptation transitions were also explored. The research methodology adopted was a review of the literature and references to case study examples. Then a four-stage multi-analytical approach was used to unravel and decode the major rural transport and climate change issues in South Africa. Consequent to the analysis, a framework of analysis for strongly integrating climate change to rural transport interventions was advanced. The findings indicated the existing rural transport adaptation measures and options in South Africa. The article concludes by highlighting the complexity and intricate dynamic nature of interactions, networks and systems that impact rural South Africa. Recommendations revolve around properly situating rural transport and climate change within the wider rural development challenges and matters facing contemporary South Africa.

Abstract. The Nile Basin is one of the most important shared basins in Africa. Managing and developing the water resources within the basin must not only address different water uses but also the trade-off between developments upstream and water use downstream, often between different countries. Furthermore, decision-makers in the region need to evaluate and implement climate adaptation measures. Previous work has shown that the Nile flows can be highly sensitive to climate change and that there is considerable uncertainty in climate projections in the region with no clear consensus as to the direction of change. Modelling current and future changes in river runoff must address a number of challenges; including the large size of the basin, the relative scarcity of data, and the corresponding dramatic variety of climatic conditions and diversity in hydrological characteristics. In this paper, we present a methodology, to support climate adaptation on a regional scale, for assessing climate change impacts and adaptation potential for floods, droughts and water scarcity within the basin.

The Impact

Many variables influence visitors’ destination choices, for example, affordability, attractions, health and safety, and expectancies. Amongst the indirect influences in destination choice by tourists, climate change is perhaps the greatest factor because of its negative impact on the ecological landscape of tourist destinations. Using the Central Drakensberg Region (CDR) as a case study, this article seeks to investigate the influence of climate change on visitors’ destination choices. A quantitative descriptive survey was conducted on a sample of n347 participants who were selected using purposive and convenience sampling procedures under the auspices of non-probability. The statistical analyses were performed using the latest edition of the Statistical Package for the Social Sciences (Version 25.0). Based on the study’s results, climate change was found to be a key influence on tourists’ decision-making, behaviour and spending habits at tourist destination like the Central Drakensberg Area. The most significant climatic parameter for tourists was determined to be pleasant and warm temperatures, as well as the summer season. Furthermore, owing to the current climate change circumstances, visitors were found to be less likely to return or recommend future visits to the region. To that end, tourism officials in the CDR should swiftly implement adaptation measures to counter the effects, and explore alternatives such as soft tourism and non-climate-dependent activities to accommodate visitors year-around. Further research is recommended to establish the extent to which socio-demographic characteristics influence destination choice in the area, as well as to ascertain the current state of climate change impacts.

Climate Action

Attention is coalescing around water and climate change, and the agendas for water security and climate action are converging. There is growing appreciation of water as a crosscutting mechanism for improving the effectiveness of global and national climate change policies (Smith et al., 2019). Water has long been recognised as a central component of climate change impacts as well as being an important consideration in mitigation and effective adaptation – where it can be both an enabling factor and a limiting factor (UN-Water, 2019). However, the connections go beyond just recognising the importance of water for climate change or simply making the “water sector” climate resilient; there is a need for system-wide coherence on water across different national and international agendas and transformational change of water management (UNESCO, UN-Water, 2020). The water crisis and the climate crisis require urgent action, and call for sustained and integrated support, leveraging complementary resources, with enhanced coordination in the context of growing uncertainties. As countries review and implement their Nationally Determined Contributions (NDCs) as part of the Paris Agreement, there is a unique opportunity to improve and enhance water management practices to increase climate resilience, improve ecosystems and reduce the risk of water-related disasters (UN-Water, 2019).

Impacts Of Climate Change

We used CMIP6 GCMs to quantify climate change impacts on precipitation and potential evapotranspiration (PET) across water management zones (WMZs) in Uganda. Future changes are assessed based on four Shared Socioeconomic Pathways (SSP) scenarios including SSP1-2.6, SSP2-4.5, SSP3-7.0, and SSP5-8.5 over the periods 2021–2040, 2041–2060, 2061–2080, and 2081–2100. Both precipitation and PET are generally projected to increase across all the WMZs. Annual PET in the 2030s, 2050s, 2070s, 2090s will increase in the ranges 1.1–4.0%, 4.8–7.9%, 5.1–11.8%, and 5.3–17.1%, respectively. For the respective periods, annual precipitation will increase in the ranges 4.0–7.8%, 7.8–12.5%, 7.9–19.9%, and 6.9–26.3%. The lower and upper limits of these change ranges for both precipitation and PET are, respectively, derived under SSP1-2.6 and SSP5-8.5 scenarios. Climate change will impact on PET or precipitation disproportionately across the WMZs. While the eastern WMZ (Kyoga) will experience the largest projected precipitation increase especially towards the end of the century, the southern WMZ (Victoria) exhibited the largest PET increase. Our findings are relevant for understanding hydrological impacts of climate change across Uganda, in the background of global warming. Thus, the water sector should devise and implement adaptation measures to impede future socioeconomic and environmental crises in the country.
