Integrated and adaptive governance of water resources: the case of South Africa

Climate change and its impact on water resources have become a reality in many parts of the world. Uncertainties in water supply as well as the gradual and abrupt change in water availability are increasing. To maintain the sustainability of the water sector, its ability to adapt to unforeseen events needs to increase. Making adaptation an integral part of the governance of water resources will thus be one of the major future challenges for the water sector. This paper focuses on how far Integrated Water Resource Management (IWRM), the guiding concept of water management and governance, is able to address these challenges and which additional features would be required for increasing the adaptability of water governance and management. In the empirical part of the paper, South African water legislation and its adaptability to the challenges of climate change is scrutinised. The paper finds that IWRM offers a number of entry points for increased adaptability. However, the IWRM concept should be complemented with features of adaptive governance such as polycentric, redundant and flexible governance structures to be better prepared for unforeseen events. It is concluded that the features of IWRM and adaptive water governance comprise a number of synergies and trade-offs, which play out differently in different combinations and contexts. The paper outlines the need for further empirical research on these trade-offs as well as on the appropriate degree of features such as participation, flexible institutions and redundancy.     

Green procurement in South Africa: perspectives on legislative provisions in metropolitan municipalities

This paper sets an objective to analyse legislative provisions for green procurement in South Africa’s metropolitan municipalities in the context of climate change and sustainable development. The main methods for data generation were interviews and document analysis. There were 30 interviews granted by among others, procurement officers, town planners and economic development specialists. In addition, 51 policy documents were retrieved, followed by a keyword search. The keywords were carefully selected and limited to those commonly used in green procurement terminology to include climate change, green procurement, renewable energy, energy efficiency, mitigation, clean technology, carbon footprint, sustainable development and green economy. The findings are that although all the metropolitan municipalities have procurement policies in place, only the City of Cape Town and eThekwini metropolitan have incorporated green procurement strategies into their supply chain management. The City of Cape Town and Nelson Mandela Bay metropolitan municipalities also emerged as the only ones with stand-alone green procurement strategies. To this end, the research concludes that legislative provisions mandating green procurement in South African metropolitan municipalities are not entirely lacking, although more work needs to be done to roll this out to cover all the existing metropolitan municipalities.     

A study on the dilemmas of resource utilization and tourism in Africa

This paper explores,explains and discusses issues around the dilemma between local conservation of natural resources(often,endangered species and habitats)and tourism needs in Africa.Often and in constitutional terms,local people have a right to exploit and use resources endowed in their local area.However,tourists often are interested in viewing the vegetation and animal resources undisturbed.Inevitably,there is an undeclared animosity of values and interests between local communities and tourists and state agencies.As a result,the dilemma is thus of governance.The purpose of this paper is to demonstrate the governance dilemma of resource utilization and tourism in Africa in a bid to create an informed stewardship framework for sustainability.This is achieved by way of case studies and narratives from Africa.As such,this paper will be a review literature on how different communities perceive tourism and derive livelihoods from their immediate environment.It also explains how the external factors influence local needs and interests.A more sustainable and operational framework that reduces friction among stakeholders is suggested.

Understanding vulnerability in southern Africa: comparative findings using a multiple-stressor approach in South Africa and Malawi

Within southern Africa, many households are facing increasing pressures as they deal with multiple challenges such as low employment, high levels of disease, environmental resources under pressure and changing political landscapes. To respond to the needs of different individuals and households, it is important to define the nature of their vulnerability. An increasing amount of theoretical and empirical work on the concept of ‘vulnerability’ has led to a range of definitions, indicators and measurement tools, which have come to characterise this field of study. As a result, there is no one general consensus. This paper presents the results from the latest in a series of applied studies conducted since 2004 by a network of scientists working in southern Africa, aimed at refining the definition and application of the concept of vulnerability. The study employed a recently developed multiple-stressor model to guide the collection and analysis of data from three sites in South Africa and Malawi. In this paper, we identify and explore five key ‘symptoms’ of vulnerability emerging from our multi-country data and reflect on the usefulness of the model employed.     

Protected areas as vehicles in population development: lessons from rural South Africa

Protected areas in developing countries are increasingly expected to move beyond biodiversity protection so as also to contribute to poverty reduction and the economic development of their surrounding communities. The purpose of this article is to report on the key findings that emerged from the assessment of a poverty alleviation programme at the Golden Gate Highlands National Park in South Africa and the lessons learned from that particular programme. Designed around outcomes analysis as an analytical framework for programme evaluation, a mixed-method approach of semi-structured interviews and focus-group sessions was used to collect data from amongst programme beneficiaries, the park management and members of the park’s advisory board. The findings indicate that although programmes of this kind can indeed impact positively on poverty levels, their direct impacts do however remain limited to a relatively small proportion of households in neighbouring communities. The article concludes that by conceptualising poverty as a multidimensional state of well-being, this allows for the exploration of a much broader range of potential social, cultural and economic benefits available from protected areas.     

Multi-stakeholder process of co-designing small-scale fisheries policy in South Africa

In 2005, a group of researchers, community-based organizations and lawyers got together with small-scale fishers to launch a class action law suit against the government of South Africa in its allocation system of Individual Transferable Quotas, on the ground that the system was unfair to small-scale fishing communities and threatened their right to practise their livelihoods. This effort resulted in the cabinet adoption of a new small-scale fisheries policy in 2014, with amendments being made to fisheries law (the Marine Living Resource Act 18 of 1998) to accommodate the issues and concerns of small-scale fisheries. Draft regulations and an implementation plan have recently been released, paving the way for the implementation of small-scale fisheries allocations in 2016. These legal and policy shifts are of great significance for small-scale fisheries, both in South Africa and elsewhere, and deserve careful examination. This paper discusses the processes leading to the development of a new small-scale fisheries policy and what has followed since. Specifically, the analysis focuses on a variety of collaborations between scholars from different disciplines; researchers from multiple fields; community practitioners representing diverse professional and community perspectives; and community organizations across local, state, national and international levels. The paper uses a model of change that crosses research and practitioner boundaries based on three key strategies: getting noticed; organizing at scale; and getting a seat at the negotiation table. It also considers the “transdisciplinary” process of involving all relevant actors in strategic, collective, reflection–action–reflection–action “from below”, which was crucial in the co-designing of this small-scale policy formulation in South Africa.     

Conservation, commercialisation and confusion: harvesting of Ischyrolepis in a coastal forest, South Africa

Harvesting of non-timber forest products is an integral component of rural livelihoods throughout the developing world. At times this is at odds with conservation objectives. Reconciliation of the two requires examination of local level contexts and needs. This paper reports on the harvesting needs for Ischyrolepis by a rural community in South Africa, against the setting that they had recently been prohibited from harvesting by the local conservation officials. Interviews were conducted with conservation officials to understand the reasoning for the prohibition. Local demand for Ischyrolepis was assessed by household surveys, as well as in-depth interviews with traders. The density and size class distribution of Ischyrolepis was determined using transects. The total annual demand for Ischyrolepis was determined to be approximately only 2.7% of the standing crop. The bulk of the annual demand was for small-scale trade, the income from which was a primary source of income for the few harvesters. Very little evidence could be found indicating that harvesting was damaging the resource or its habitat, and local knowledge suggested that the abundance of the species was stimulated by harvesting. Even if market demand were to increase, the size of the shoots required means that less than 20% of the standing crop could be harvested annually. Current regulations around harvesting are in a state of revision, and hence confusion prevails regarding if harvesting is permissible, and if so, under what conditions, which is detrimental to both conservation and livelihoods.

社会选择理论在流域跨界水资源配置冲突决策问题中的应用

本文将社会选择理论引入到流域跨界水资源配置冲突的解决研究中,从群决策的角度寻找到流域内各区域一致同意的、满足水量分配公平的流域水资源配置方案。流域水资源配置冲突问题从表面上看是资源问题,实质上却是一个典型的决策问题。作为一种具有混合特性和稀缺性的自然资源,流域稀缺水资源的分配实质上是多主体参与的涉水利益分配,而分配的核心问题是如何通过合理的群决策机制协调水资源配置冲突中不同行政区域之间的利益关系进而实现公平。本文提出基于社会选择理论的流域跨界水资源配置冲突解决框架,首先从公平性角度将流域水资源配置冲突看成一个短缺资源的配置问题,利用P、AP、CEA和CEL四种破产准则获取可行的水量分配方案集合;其次运用社会选择理论中的PV、BC、HQ、PCM和FB五种偏好聚合方法进行流域内各行政区域个体偏好聚合的群决策分析;通过破产准则与偏好聚合的结合能够实现流域水资源配置冲突群决策结果的公平,所得流域水量分配方案易于被冲突主体所接受。最后,以华北缺水地区的漳河流域跨界水资源配置冲突问题为例进行研究,并比较不同破产准则及偏好聚合方法在解决流域跨界水资源配置冲突中的应用。研究结果表明,社会选择理论与破产准则的结合在解决流域跨界水资源配置冲突问题中具有较高的实用价值。     

The development and unraveling of marine resource co-management in the Pemba Channel,Zanzibar: institutions,governance, and the politics of scale

Marine resource management programs face conflicting mandates: to scale-up marine conservation efforts to cover larger areas and meet national and international conservation targets, while simultaneously to downscale and decentralize management authority to resource users and local communities. These conflicting goals create tensions in marine resource management. This paper explores these tensions by presenting and evaluating the outcomes of a fisheries co-management program on the island of Pemba, Tanzania, where institutions and scale were configured and reconfigured under externally funded programs to improve marine conservation through co-management. The initial institutional arrangements for co-management supported a functioning system to protect marine resources, ensure fishermen’s access, and distribute tourism revenues. However, a subsequent push to scale-up marine management reconfigured institutional arrangements and power in a more hierarchical and potentially weaker system. With the expansion of the co-management program, protected area coverage, financial resources, and the number of community organizations created for fisheries co-management expanded tremendously; however, community participation in marine management decreased, and the fishermen’s association previously involved in co-management dissolved. Several factors contributed to this outcome: inadequate time to solidify co-management institutions and arrangements, diverse resource users inexperienced with local management, a sudden and substantial new source of funding, and political pressures to restructure marine management. Rather than focusing primarily on expanding coverage and devolving authority, it is important to adapt co-management arrangements to the local contexts in which they operate.     

The Economic Consequences of Alien Plant Invasions: Examples of Impacts and Approaches to Sustainable Management in South Africa

The invasion of natural ecosystems by alien plants is a serious environmental problem that threatens the sustainable use of benefits derived from such ecosytems. Most past studies in this field have focussed on the history, ecology and management of invasive alien species, and little work has been done on the economic aspects and consequences of invasions. This paper reviews what is known of the economic consequences of alien plant invasions in South Africa. These economic arguments have been used to successfully launch the largest environmental management programme in Africa.Ten million hectares of South Africa has been invaded by 180 alien species, but their impacts are not fully understood, although they are undoubtedly significant. The indications are that the total costs of these impacts are substantial. Selected studies show that invasions have reduced the value of fynbos ecosystems by over US$ 11.75 billion; that the total cost of invasion would be about US$ 3.2 billion on the Agulhas Plain alone; that the net present cost of invasion by black wattles amounts to US$ 1.4 billion; that invasions by red water fern have cost US$ 58 million; and that the cost to clear the alien plant invasions in South Africa is around US$ 1.2 billion. These few examples indicate that the economic consequences of invasions are huge.One of the unique aspects of invasive plant control programmes in South Africa has been the ability to leverage further benefits (mainly through employment) for the expensive control programmes from the government's poverty relief budget. This has made it possible to allocate substantial funding to a programme that would otherwise have struggled to obtain significant support. Biological control of invasive species also offers considerable benefits, but is often the subject of debate. We believe that, at least in the case of many invasive alien plant species in South Africa, biological control offers one of the best, and most cost-effective, interventions for addressing the problem.     

Assessing agricultural land-use change in the Midlands region of KwaZulu-Natal,South Africa: application of mixed multinomial logit

On-farm tree cultivation is considered an important strategy to mitigate detrimental environmental impacts of agricultural land-use change (ALUC). In South Africa, however, little is known about farm-level incentives and constraints that govern ALUC decisions among small-scale farmers. To address this knowledge gap, this study employs a mixed multinomial logit model by using a combination of revealed and stated preference data. After correcting for endogeneity, the estimated results show that decisions about ALUC are rationally derived and driven by clear but heterogeneous preferences and trade-offs between crop productivity, food security and labour saving. The results further show that the decision to plant sugarcane is constrained by landholding, whilst farmland afforestation is negatively influenced by household size. Decisions to convert land use are also driven by the behaviour of peer groups and agro-ecological conditions. Based on these findings, important policy implications for sustainable land use are outlined.     

Regional consequences of the way land users respond to future water availability in Murcia, Spain

Agricultural development in the Murcia autonomous region, Spain, has led to overexploitation of groundwater resources, and climate change will further increase pressures. Policy options to tackle the current unsustainable situation include the development of inter-basin water transfer (IBWT) schemes from wetter regions in the north and the introduction of taxation to further control groundwater abstraction. Under these scenarios, farmers with current access to water could face higher water cost, whereas farmers in areas where water was previously not available could see first time availability of water resources. In this paper, we combine discrete choice-based interviews with farmers in the Torrealvilla catchment, in which they indicate how they would adapt their land use under different scenarios, with an input–output model to assess the aggregate effects of individual land use decisions on the economy and water consumption of the Murcia region. The paper presents steps taken in the development of an input–output table for Murcia, including disaggregation of the agricultural sector, accounting for sector water use and consideration of back- and forward linkages. We conclude that appropriate taxation can lead to better water use efficiency, but that this is delicate as relatively small changes in prices of agricultural products can have significant impacts on land use and water consumption. Although new IBWT schemes would enable water to be used more efficiently, they would considerably increase regional water consumption and the regional economy’s dependence on water. As this is not sustainable under future climate change, water saving development pathways need to be explored.     

Evaluation of 38 years of radiological environmental data for the nuclear research facility in South Africa

Environmental monitoring has been conducted at the South African National Nuclear Research Facility (Necsa site) for the past 38 years. Included in this monitoring programme was the assessment of water, fish and sediment samples. The objective of this project was to review the data of these assessments to establish if the Necsa activities had any impact on the environment. An assessment of the management of discharge limits was included in the review. Fluctuations in the data reviewed can partly be ascribed to errors in sampling techniques and analysis methods, but mostly to external factors. Two main external factors identified during the review were: dilution effects based on the flowrate in the Crocodile River and the percentage of full capacity of the Hartbeespoort Dam, and the atmospheric fallout from nuclear weapons testing. In this project, the impact of these factors were investigated with the help of correlation coefficient calculations and graphs. It was concluded that the flowrate of the Crocodile River and percentage full capacity of the Hartbeespoort Dam did have an impact on the beta activity measured in water and fish samples, and the (nat)U activities measured in water samples. The measured fallout from nuclear weapons testing in the southern hemisphere also had an impact on the beta activity in water. The assessment of the environmental monitoring data also showed that accidental releases were measurable in the environment. The added routine impact to a member of the public downstream from Necsa was on average an annual dose of 0.54 microSv more than that to a person living upstream from Necsa, which is considered insignificant in international radiation protection norms. The conclusion can be made that the monitoring programme is successful in satisfying its main objective, which is to determine the effects of the discharges on the environment and the immediate population.
