Africa particularly has been experiencing the world’s most rapid rate of urbanization and cities are faced with the resulting pressure on natural resources. Water is one of the resources under pressure and the provision thereof is complicated by the deteriorating quality and quantity thereof. This study takes a brief look at the water situation in a water scarce region in Africa and concentrates on the urban water supply sector. It takes an in depth look at the measures used to secure water supply to a city in this very dry part of the world. The area under study is Windhoek, the capital of Namibia, situated in the southwestern corner of Africa. Namibia is the driest country in Sub-Saharan Africa and is characterised by a semi-arid nature, which results in a very hot and dry climate with erratic rainfall patterns. Windhoek has a low average rainfall associated with very high evaporation rates. No permanent water bodies exist near the city and the bulk of Windhoek’s water supply comes from storage dams quite a distance from the capital. Most of these sources of supply have been developed and are nearing the limit of their potential. A desperate need therefore exists to develop reliable additional water resources to secure the water supply especially during periods of prolonged drought. The case study gives examples of the initiatives taken by water authorities to improve the security of supply and keep up with the growing demand in the city. These initiatives include a dual pipe system for the distribution of semi-purified sewage for irrigation, reclamation of domestic sewerage, aquifer recharge and the implementation of Water Demand Management principles. An analysis of the most efficient and cost-effective means of supply augmentation namely aquifer recharge, have been balanced against the potential water savings of Water Demand Management in the city. The study also takes a brief look at the principles of Integrated Water Resource Management and how it is incorporated in the strategies used to augment supply to the city. The research found aquifer recharge as the most efficient and cost-effective means to augment supply to the city and together with Water Demand Management creates an approach complying with the goals of Integrated Water Resource management. The study concludes by identifying gaps in demand management in the city. It also suggests relevant recommendations on how to increase the effectiveness of Water Demand management.
AFRIKAANSE OPSOMMING: Verstedeliking is ‘n komplekse verskynsel en ‘n tendens wat regoor die wêreld voorkom. Die hoogste voorkoms van verstedeliking vind in Afrika plaas wat groot druk plaas op die natuurlike hulpbronne van stede. Water is een van die hulpbronne onder druk en die voorsiening daarvan word bemoeilik deur die verswakking van die kwaliteit en die beskikbaarheid daarvan. Hierdie studie konsentreer op die watersituasie in ‘n waterskaars streek in Afrika en die stedelike watervoorsieningssektor. Dit behels ‘n in diepte ondersoek na metodes wat gebruik word om die watervoorraad van die stad te verseker in hierdie droogte gesteisterd deel van die wêreld. Die gebied onder bespreking is Windhoek, die hoofstad van Namibië, wat geleë is in die Suidwestelike deel van Afrika. Namibië is die droogste land in die Sub-Saharastreek en word gekenmerk deur gereelde droogtes met ‘n gepaardgaande warm droë klimaat en onreëlmatige reënvalpatrone. Windhoek word gekenmerk deur ‘n lae gemiddelde reënval met ‘n baie hoë verdampingstempo. Geen permanente waterbronne kom in die nabyheid van die stad voor nie en die watervoorraad word gestoor in opgaardamme wat redelik ver van die hoofstad geleë is. Hierdie voorsieningsbronne is voortdurend in gebruik en die voorraad is beperk. Daar onstaan dus ‘n dringende behoefte aan betroubare bykomende waterbronne om voortdurende voorsiening aan die stad te verseker veral gedurende aanhoudende droogtes. Die gevallestudie konsentreer op voorbeelde en inisiatiewe wat deur die Water Owerhede geneem word om die voorsiening van water, aan die immergroeiende behoeftes van die stad te verbeter en te verseker. Hierdie pogings sluit in,‘n dubbele pyplynsisteem vir die verspreiding van halfgesuiwerde rioolwater vir besproeiingsdoeleindes, herwinning van huishoudelike rioolwater, herlaai van ondergrondse watervoorraad en die implimentering van wateraanvraag bestuursmaatreëls. Die geskiktste en mees koste-effektiewe metode van verhoogde watervoorsiening naamlik die herlaai van ondergrondse waterbronne, is ontleed, en die voordele opgeweeg teen die potensiële waterbesparing deur die Bestuur van Wateraanvraag in die stad. Daar is ook kortliks gekyk na die beginsels van Geintigreerde Water Bronne Bestuur en hoe dit by bestaande strategieë ingelyf is om uitbreiding van voorsiening aan die stad te verseker. Die navorsing het bevind dat die herlaai van ondergrondse waterbronne as die geskikste en mees koste-effektiewe metode beskou kan word om die verhoogde aanvraag van die stad die hoof te bied. Die studie word afgesluit deur die tekortkominge in die Water Aanvraagbestuur van die stad te identifiseer. Relevante aanbevelings word gemaak van hoe om die effektiwiteit van hierdie betrokke strategie te verbeter.

Повний текст джерелаA quantidade, a disponibilidade e, em particular, a qualidade da água doce está em degradação progressiva devido às mudanças ambientais no Antropoceno. Estratégias de adaptação baseadas em ecossistemas (EbA) são essenciais para reduzir estes impactos. Propõe-se um novo modelo de gerenciamento de recursos hídricos que integre a pegada hídrica cinza e processos ecohidrológicos para avaliação dos serviços hidrológicos em bacias hidrográficas sob mudanças. As etapas da pesquisa são: Capítulo 2 – análise dos projetos de pagamentos por serviços ambientais de proteção às bacias hidrográficas na Mata Atlântica brasileira e, no contexto de EbA, indicação de variáveis ecohidrológicas úteis na quantificação e futura valoração dos serviços hidrológicos; Capítulo 3 – desenvolvimento de plano de monitoramento ecohidrológico que integra aspectos qualitativos e quantitativos dos recursos hídricos para projetos de EbA; Capítulo 4 – provisão de dados experimentais de qualidade e quantidade da água, além de observações in-situ, para investigação das influências das mudanças de uso e ocupação do solo nas cabeceiras de mananciais, estratégicos para o abastecimento público e a conservação ambiental; Capítulo 5 – estimativas da pegada hídrica cinza para nitrato, fósforo total e sedimentos a partir do monitoramento de variáveis quali-quantitativas em bacias com diferentes condições de uso e ocupação de solo. Foi realizada a instalação de três Plataformas de Coleta de Dados, por meio de parceria entre EESC, ANA, CPRM, CEMADEN, SMA, TNC e WWF, visando aumentar a resiliência do sistema, decorrente de futuro aprimoramento da gestão, para a segurança hídrica. A metodologia incluiu coletas em seis diferentes períodos, durante dois anos, e análises das variáveis condutividade elétrica, cor, DQO, DBO5,20, nitrato, nitrito, nitrogênio amoniacal, fosfato, pH, turbidez, sólidos totais, coliformes termotolerantes, Escherichia coli, medidas de vazões e velocidades médias em seções transversais. O método foi aplicado em microbacias participantes dos projetos Produtor de Água/PCJ e Conservador das Águas, dentre outras, com áreas de drenagem entre 7 e 1.000 km2, que contribuem para a bacia do rio Piracicaba (12.530 km2). Dados primários, medidos em recente período de severa estiagem no Sistema Cantareira (2013-14), foram integrados aos bancos de dados de órgãos gestores federais e estaduais. A produção de água foi maior em sub-bacias menos florestadas. Foi possível aprimorar a regionalização de cargas poluidoras por área de drenagem na região do Cantareira. A pegada hídrica cinza (WF) foi estimada a partir de simulações no modelo ecohidrológico Soil and Water Assessment Tool (SWAT). Curvas de permanência de vazões e carga poluidora por área de drenagem foram elaboradas. Supondo-se a continuidade dos projetos \"Produtor de Água/PCJ\" e \"Conservador das Águas\", foram investigados os impactos de cenário futuro de uso do solo. Finalmente, foi desenvolvido novo índice ecohidrológico para quantificação dos serviços hidrológicos e avaliação a sustentabilidade das sub-bacias, a partir da pegada hídrica cinza composta. Assim, usando ferramentas de vanguarda tecnológica (SWAT e WF), a tese fornece subsídios para uma melhor compreensão dos impactos antropogênicos sobre os recursos hídricos e novas estratégias de adaptação baseada em ecossistemas, frente às progressivas taxas de perda de serviços ambientais.

Повний текст джерелаA avaliação da segurança hídrica pode incorporar vários conceitos relacionados à água, desde aspectos da política de recursos hídricos até questões hidrológicas específicas e suas interações com a sociedade e ecossistemas. Esta tese de doutorado busca estabelecer uma base conceitual e propor esquemas metodológicos com base determinística e estocástica para avaliação da segurança hídrica de bacias hidrográficas. Objetivos específicos são definidos em cada capítulo e relacionam-se à gestão do \'Sistema Cantareira de abastecimento de água\' (localizado no Sudeste do Brasil), com foco em diferentes escalas, bem como aspectos políticos e hidrológicos. O primeiro capítulo é apresentado como baseline conceitual, examinando aspectos gerais da política de recursos hídricos e sistemas alocação de água. Este estudo compara sistemas de gestão aplicados a projetos de transposição de água inter/intra-bacias no Brasil e Estados Unidos, discutindo experiências do Sistema Cantareira e da bacia do rio Colorado. O segundo capítulo, por sua vez, propõe e analisa um esquema metodológico determinístico baseado na gestão das águas azul e verde (definidas de acordo com processos hidrológicos e unidades de armazenamento). Este estudo demonstra como uma análise quantitativa da provisão e utilização de ambos os tipos de água pode ser conduzida, propondo indicadores de escassez e vulnerabilidade hídrica. Esta abordagem foi aplicada em uma bacia agrícola (291 km²), localizada a montante do reservatório Cachoeira, que é integrante do Sistema Cantareira. O terceiro capítulo quantifica e analisa os impactos das incertezas sobre os indicadores de segurança hídrica propostos no capítulo 2, utilizando um esquema metodológico estocástico baseado em múltiplos modelos e reamostragem, que incorpora variadas fontes de incerteza, tais como: i) dados observados de vazão; ii) estrutura do modelo hidrológico; iii) análise de resíduos do modelo hidrológico; iv) estimativa de vazão ambiental; v) definição de condições críticas de provisão e vi) demanda hídrica. Em seguida, as incertezas são propagadas através de diferentes arranjos metodológicos aplicados na mesma bacia estudo do capítulo 2. Em conclusão, o primeiro capítulo sugere uma potencial troca de contribuições provenientes de ambos os sistemas de gestão brasileiro e americano. O segundo capítulo revela padrões espaciais e temporais dos resultados dos indicadores de escassez e vulnerabilidade, melhorando assim a compreensão de como e onde ameaças à segurança hídrica podem surgir. Por sua vez, a análise de incertezas desenvolvida no terceiro capítulo é capaz de gerar suporte a gestores de recursos hídricos e processo de tomada de decisões robustas. Recomendações específicas são geradas em cada capítulo da presente tese de doutorado.

Повний текст джерелаThe São João stream is the strategic source for supplying the municipal headquarters of Porto Nacional. This dissertation aimed to identify the main risks and vulnerabilities to the public supply of Porto Nacional / TO, associated to the quantity and quality of raw water of the Córrego São João basin, and to analyze the level of current and future water security of the municipality. We adopted the model developed by members of the Research Group "Water, Water Management and Safety in times of Global Environmental Change".Thus, it was possible to develop a methodology of analysis of water security of urban supplies, specific to the São João Stream basin in Porto Nacional / TO, considering four stress factors considered as the most determinant for current vulnerability: i) pressure On environmental conditions; Ii) demand for water; (Iii) pollutant load and (iv) extreme hydrological events. The results showed that the greatest stressor to the water security of the supply of Porto Nacional, related to the problems of quantity and quality of raw water, is the demand for water. On the other hand, the pressure on the environmental conditions of the Basin was evidenced by the preparation and analysis of maps of land use and occupation in 2006, 2011 and 2016; The evolution (in time and space) of the anthropic occupation with implantation of temporary crops and of pastures, besides the notorious urban expansion, was verified. We did not identify any records of total paralysis of ETA 02. The main result shows that, currently, there is still compatibility between the quali-quantitative availability of the raw water of the São João Stream and the subsystems of capture and treatment of ETA 02.

Повний текст джерелаAfter several years of political and economic successes made since 1994, South Africa continues to experience major challenges in water availability, increased poverty, high levels of unemployment and more recently, steep increases in food and fuel prices. The Eastern Cape Province of South Africa is one of the regions that have been negatively affected by changes in climate variability, thereby, increasing the vulnerability and subjecting a significant number of households to increased poverty; water scarcity and food insecurity. The situation continues and there is a need to address this. This study sought to understand how the local households in the Eastern Cape Province in Nqgeleni location adapt to the extreme drought which impacts on their livelihood by exploring the different adaptive measures or systems that are implemented to cope with the climatic conditions in uplifting and providing food and nutrition security for sustainable growth and development. The primary aim of this research was thus to investigate how water scarcity influences food and nutritional security on rural household in Nqgeleni location. To achieve this aim, three secondary objectives were formulated. Firstly, to establish the relationship between water scarcity on food and nutritional security of rural households in Nqgeleni location. Secondly, to identify the drivers of water scarcity in the area. Lastly, to create an inventory of coping mechanism employed by rural households with water scarcity, food and nutritional security. An extensive literature review was undertaken to integrate prior findings and theories on water scarcity, food and nutritional security. The literature study revealed that water scarcity has a significant impact on food security. In addition, several factors such as demographic profile variables (population growth) and structural inefficiencies (infrastructure and management) were identified as potential drivers of water scarcity. In order to address the objectives set for this study, a number of items were sourced from the literature and a structured questionnaire administered to respondents who were selected by means of a simple random sampling technique. Data was collected from 111 usable questionnaires. The mixed method approach was employed as a core research methodology. The responses obtained were subjected to statistical analyses. Cronbach-alpha coefficients were calculated to confirm the internal consistency of the measuring instrument. The findings from this study are thus as follows. There was a significant relationship between water scarcity, food and nutritional security. Food security also has an impact on nutritional security. In addition, the drivers of water scarcity found in this study includes population growth, lack of infrastructure and poor management of water related issues by the municipality; all of which confirm findings in other studies. Furthermore, a number of respondents profile variables were identified as contributing factors to poverty, vulnerability, water scarcity, food and nutritional security in the Nqgeleni location. This includes lack of education, size of the household, and income level of the household. Based on the above findings, an inventory of coping mechanism was recommended to assist the rural households deal with water scarcity, food and nutritional security. This study has added to the empirical body of water scarcity, food and nutritional security in South Africa and the world at large.

Many rural communities of South Africa are living without adequate water supplies mainly due to historical lack of infrastructure and effective water reticulation systems. Day to day challenges of accessing water from distant boreholes and rivers are a reality particularly for women and children in rural Limpopo. This study investigates the nature and extent of water supply problems and how communities are living without adequate water in three rural communities of Greater-Giyani Local Municipality in South Africa. The study area lies in a semi-arid region which regularly experiences climate extremes such as droughts and floods which can reduce the ability of the municipality to supply water. Primary data was collected through questionnaires, key informant interviews and field observations while population, climate and hydrological data are also analyzed. A mixed methods research design was employed using qualitative methods such as content analysis whilst quantitative methods were dominated by time series analysis techniques and online interactive climate platforms such as the Climate Engine. It was found that households, schools and clinics in the study area rely mainly on boreholes for water supply but sometimes rivers supply those living nearby. An incomplete and poor water reticulation system coupled with erratic and shortening summer rainfall seasons are some of the major causes of water shortages in the study area. In order to cope with inadequate water, community members and public institutions in the study area have drilled boreholes and the sustainability of groundwater in the area is not well established. During summer, most households and institutions practise rainwater harvesting while a few resort to purchasing water from vendors. Despite these challenges which are not well documented, it was concluded that most of the rural poor households and institutions in the study area are well adapted to cope with water scarcity in the short term, while being vulnerable in the long term due to population growth and climate change. The study recommends the need for government and municipalities to invest in water reticulation systems in the long term whilst providing water to affected rural communities through water tankers, drilling more boreholes and maintenance of existing ones. Lessons learnt from this study may be useful to other municipalities across South Africa that are grappling with challenges of water access and supply.

Повний текст джерелаWater is a key element linked to challenges such as food security, economic development, energy generation and climate change. South Africa experienced its driest year on record in 2015, together with one of the largest cities, Cape Town, almost running out of water in 2018. The likelihood of increased drought in the future coupled to climate risks makes it imperative to attend to water security concerns within the country. The business sector needs to pay more attention to water issues given its reliance on water for operation. This study explores how South African companies that are dependent on water respond to water security concerns linked to increased demand and variability. Focusing on the potential of the CDP Water reporting process to promote improved water stewardship practices. A mixed methods approach is used including a detailed investigation of CDP Water report data and interviews. Companies are unique in their responses, their perception of water risk hence determines their responses to the risk. Many companies showed misalignments between their company strategy, governance and practice in water decision making that further calls into question their water stewardship in addressing water security concerns. Although water stewardship is highlighted as an opportunity for various companies, engagement in practices that promote stewardship is low. In the pursuit of water stewardship practices and improved water management, context becomes key. By companies conducting comprehensive river basin assessments, it assists in addressing and engaging water risks in a local context. Beyond CDP reports and interviews, an underlying outcome has emerged that calls for effective sustainability/ environmental strategic planning in environmental departments within companies. Communication becomes an essential tool even though creating a business case around risk is not unique to water. An emphasis is then needed at Board level on effective leadership within a company to transform the way they view their water related risks and turn them into opportunities. To bring these findings together, archetypes were created based on company ‘water stewardship readiness.’ The archetypes encompassed the likelihood of companies engaging in water stewardship practices as this is seen as one of the best ways forward for business to assist in securing water in the country. The notion of a water champion to tackle water related risks and lead opportunities brings to light the value of education and creating individuals, regardless of their field of interest, with the understanding and knowledge that resources such as water are limited. Environmental issues should be embedded within these individuals for appropriate decision making given the current state and future projections of not only water, but environmental concerns going forward.

Повний текст джерелаNa atualidade, as questões relacionadas com a qualidade da água são cada vez mais uma realidade. Do mesmo modo, existem cada vez mais preocupações relacionadas com o seu impacto na saúde pública. De facto, a junção da escassez deste elemento tão importante para a vida, e a possibilidade de veiculação de doenças transmitidas pelo meio hídrico fazem com que haja, neste momento uma grande preocupação a nível mundial relacionada com estas questões, quer seja o uso que se lhe dá, a quantidade disponível e, a qualidade que esta apresenta. Assim, existe uma forte recomendação por parte da Organização Mundial da Saúde, para a implementação de novas metodologias e políticas neste âmbito. Também a entidade reguladora responsável pelo sector de águas em Portugal, apela de forma ativa à introdução de novas metodologias por parte das Entidades Gestoras, e deste modo garantir que se está no caminho certo e que a água aqui produzida é efetivamente de qualidade e que satisfaz de forma contínua os requisitos dos consumidores. Neste contexto, as duas entidades anteriormente mencionadas, alertam, a nível nacional, as Entidades Gestoras responsáveis pelo abastecimento de água, para a introdução de novas metodologias que tenham por base uma abordagem preventiva, e que assim analisem o sistema, etapa a etapa desde a origem da água até ao consumidor final, antecipando todos os riscos a que o mesmo se encontra sujeito. A metodologia de Plano de Segurança da Água, assenta nos princípios anteriormente mencionados. O presente trabalho apresenta uma descrição das várias etapas do desenvolvimento do Plano de Segurança da Água da Zona de Abastecimento de S. Nicolau, a cargo da Câmara Municipal de Cabeceiras de Basto. Este plano foi realizado com base numa abordagem de identificação e avaliação de possíveis riscos a que o sistema poderá estar sujeito. Assim conseguiu identificar-se um conjunto de Pontos Críticos de Controlo, estabelecer Planos de Monitorização Operacional com as instruções necessárias ao correto funcionamento do sistema e um conjunto de ações corretivas a adotar para um melhor funcionamento do sistema.
Currently, the matters relating to water quality are increasingly becoming a reality. Likewise, there is growing concerns regarding their impact on public health. In fact, the junction of the shortage of this element so important for life, and the possibility of binding diseases transmitted by the water environment contributed to the existence at the moment of a major concern worldwide related to these issues, whether it is its use, its available quantity or the its quality. Thus, there is a strong recommendation by the World Health Organization, to implement new methodologies and policies in this area. Also the regulatory body responsible for the water sector in Portugal, calls actively for the introduction of new methodologies by the Management Entities, and thus ensuring that they are on track and that the water here produced is actually of quality and that it continuously satisfies the consumer requirements. In this context, the two aforementioned entities, alert, at national level, the Managing Authorities responsible for the water supply to the introduction of new methodologies which are based on a precautionary approach and thus analyze the system, step by step from the water source to the final consumer, anticipating all the risks to which it is exposed. This methodology is based on the principles of the Water Safety Plan. The present work presents a description of the various stages of the development of the Water Safety Plan of the Supply Area of S. Nicolau, responsability of the Municipality of Cabeceiras de Basto. This plan was developed based on an approach of identification and evaluation of possible risks to which the system may be exposed. Thereby it was possible to identify a set of critical control points, to establish Operational Monitoring Plans with the needed guidelines for the correct operation of the system and a set of corrective actions to be adopted to improve the functioning of the system.
