AbstractGujarat has made important strides to ensure that most parts of the state become water secure. In 2005, Gujarat was one of the few states that recognized that its urban areas were its ‘engines of growth’ and made significant investments in urban infrastructure. A state-wide water supply grid was constructed to transfer inter-basin water from perennial surface water sources to water-scarce areas. While these schemes have improved household-level access to municipal water supply, service levels have not improved. In this paper, we argue that along with infrastructure creation, there is a need to focus on monitoring, operation and maintenance of existing system and improving efficiency. We analyze information available from the performance assessment system (PAS) setup by the CEPT University for monitoring of urban services in India. It has annual information of water service delivery in all the urban areas of Gujarat from 2010. We assess urban drinking water supply on three key aspects: equity, service quality and financial sustainability. We also identify a few key intervention areas related to increased accountability, efficiency and equity in delivery of water supply services.

This study aimed to examine the influence of agricultural development under urbanization on agriculture water supply internalization. Water supply internalization is the process of measuring water security to estimate the degree of water supply sustainably by region inside. According to water users, Water supply internalization could be divided into Agriculture and urban water supply internalization. Agriculture and urban water supply internalization are calculated in this study. This study employed a spatial model to analyze agricultural water supply internalization and its influencing factors. The results showed that the agriculture development associated with agricultural population and crop typology impacts agricultural water supply internalization. Urban water supply internalization increases lead to an increase in agricultural water supply internalization. The agricultural population’s spatial agglomerations lead to increased agricultural water supply internalization. Agricultural population’s spatial agglomerations mean neighborhood city agriculture population share similar trend. Agricultural and urban water supply internalization have spatial autoconnection. The study area consisted of 30 cities in four provinces in North China: Beijing, Tianjin, Hebei, and Shandong.

<p>The Segura Hydrographic Demarcation (DHS), in Southeastern Spain, is an area of hydric deficit caused by low and irregular rainfall and a dense population. In this region water scarcity is a burning issue that polarizes society for or against different models of ensuring water supply. Given the current demand for water throughout Spain, desalination has been used to increase water supply, and as insurance against drought. Ten seawater desalination plants and hundreds of brackish aquifer desalination plants treat water in the Southeast of the Iberian Peninsula, both for human consumption and for irrigation, contributing to economic, energetic, processual and economic aspects of territorial organization in the Southeast of Spain. This article reviews debates over desalination, water transfers, and the best way to meet water demands in that region. While desalination allows an increase in water supply, dependence on that source increases energy costs and may lead to mistaken assumptions among users about water scarcity and availability.</p><p><strong>Keywords: </strong>seawater desalination, brackish aquifer desalination, human water supply, social debate, irrigation, Southeast of Spain</p>

This article highlights various features of risk and resilience standard developed by the ASME-ITI and American Water Works Association. The American Water Works Association and ASME Innovative Technologies Institute have jointly developed an American National Standard to enhance the security and resilience of drinking water and wastewater systems. The ASME-ITI, under the Department of Homeland Security’s sponsorship, initiated discussions with the water sector to consider the development of sector-level guidance based on RAMCAP Plus. The RAMCAP Plus process is composed of seven interrelated analytic steps, which provides a foundation for data collection and interpretation, analysis, and decision making valuable for understanding and managing risk and resilience. The process is designed to guide the selection of options that reduce risk and increase resilience, including informing funding decisions. The joint standard fulfils the need identified in the water sector-specific plan. It facilitates the reduction of risk and the enhancement of resilience at water and wastewater systems across America.

Water security is a global concern because of the growing impact of human activities and climate change on water resources. Studies had been performed at global, country, and city level to assess the water security issues. However, assessment of water security at a domestic scale is lacking. This paper develops a new domestic water security assessment framework accounting for water supply, sanitation, and hygiene through twelve indicators. Water supply, sanitation, and hygiene are central to key water-related sustainable development goals. The framework is subsequently applied to the city of Addis Ababa, Ethiopia. From the domestic water security assessment of Addis Ababa, the water supply dimension was found to be of good level, whereas the sanitation and hygiene dimensions were of poor and fair level, respectively, indicating both a challenge and an opportunity for development. Because the analysis is spatially explicit at the city-branch level (in Addis), variation in domestic water security performance across Addis Ababa can be assessed, allowing efficient targeting of scant resources (financial, technical, personnel). Analysis further shows that a lack of institutional capacity within the utility, existing infrastructure leading to ‘lock-in’ and hindering maintenance and upgrade initiatives, and an unreliable power supply are the main issues leading to poor domestic water security in the study city. These areas should be tackled to improve the current situation and mitigate future problems. The developed framework is generic enough to be applied to other urban and peri-urban areas, yet provides planners and policy makers with specific information on domestic water security considering water supply, sanitation and hygiene, and accounting for within-city variability. This work could therefore have practical applicability for water service providers.

ENGLISH ABSTRACT: Urbanisation is a complex phenomenon and is a trend witnessed across the globe. 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.

Water quantity, availability and, particularly, quality of Brazilian freshwater is under progessive degradation due to Anthropocene\'s environmental changing conditions. Strategies of Ecosystem-based Adaptation (EbA) are essential to mitigate these impacts. This Ph.D. thesis proposes a new model of water resources management, thereby integrating selfpurification and ecohydrologic processes to evaluate ecosystem services from watershed under change. In Chapter 2, this thesis examinates the payment for hydrologic cosystem services (Water-PES) in Brazilian Atlantic Forest and points ecohydrologic variables useful for assessing and further valuing hydrologic services. In Chapter 3, this thesis discusses proposals for freshwater monitoring plan which integrate quali-quantitative aspects for EbA and Water-PES projects. Therefore, in Chapter 4 experimental quali-quantative freshwater data from in-situ field observations are investigated according land-use/land-cover (LULC) in headwaters of water supply systems. In Chapter 5, through simulated impacts on freshwater yield from scenarios of LULC change, the grey water footprint (greyWF) is assessed, as well as environmental sustainability of sub-basins is depicted from a new ecohydrologic index for assessing hydrologic services. The methodology is performed using through field sampling and lab-analysing of physico-chemical, biologic and hydraulic variables in nested sub-basins draining to the Cantareira Water Supply System, in Sao Paulo and Minas Gerais states, Brazil. These areas participate in the Water-PES projects Water Producer/PCJ and Water Conservator at headwaters of Piracicaba watershed, during recent severe drought conditions between years 2013-15. The greyWF is estimated from outputs of time series simulated through ecohydrologic model Soil and Water Assessment Tool (SWAT). Under assumption of continuity of Water-PES projects, and using the same series of hydrometorological records for a common period (2008-2014), freshwater quali-quantitative impacts are performed through three LULC scenarios: past situation \"S1\" (year 1990), current situation \"S2\" (year 2010) and future situation \"S2+EbA\" (year 2035). From these scenarios, flow and load duration curves, mean water yields, greyWF and seasonal variabilities, were simulated. Through this research, continuous-monitoring Data Collecting Stations were installed in public-private partnership encompassing EESC/USP, ANA, CPRM, CEMADEN, SMA, TNC, WWF and local mayors. This continuous monitoring is addressed to increase the system resilience, based on better decision-making for water security, in strategic headwaters not only for water supply, but also for environmental conservation. This doctoral thesis brings contributions to a better comprehension of anthropic impacts on water resources and for strategies of EbA in front of progressive rates of losses of ecosystem services. This PhD. thesis was part of three research initiatives which partly granted activities: (1) Thematic Project FAPESP 2008/58161-1 \"Assessment of Impacts and Vulnerability to Climate Change in Brazil and Strategies for Adaptation Options\"; (2) \"INCLINE - INterdisciplinary CLimate INvEstigation Center\" (NapMC/USP Núcleo de Apoio às Pesquisas em Mudanças Climáticas) and (3) \"Água Brasil\" Project, Banco do Brasil Foundation, WWF Brazil, ANA & FIPAI/EESC-USP.
A 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. Esta tese esteve vinculada a três projetos de pesquisa, dos quais obteve apoio financeiro: (1) Projeto Temático FAPESP 2008/58161-1 \"Assessment of Impacts and Vulnerability to Climate Change in Brazil & Strategies for Adaptation Options\"; (2) \"INCLINE - INterdisciplinary CLimate INvEstigation Center\" (NapMC/USP) e (3) Projeto \"Água Brasil\", Fundação Banco do Brasil, WWF Brasil, ANA e FIPAI/EESC-USP.

Drinking water supply insecurity is globally on the rise, and prevalent in most low and middle-income urban areas. Multiple responses have emerged to cope with the lack of a reliable and equitable supply of safe and sufficient drinking water in cities, which presents a wide range of social-ecological implications. Yet, many of the analyses to date are focused on predominantly technological, ecological, and economic perspectives, overlooking broader cultural and political dimensions. What are the elements and the interrelationship between them that sustain the lack of drinking water supply security at an urban scale? The empirical case study is located in Mexico City, the capital city of one of the most drinking water-insecure countries globally and among the world’s five largest metropolitan areas. Qualitative data is elicited from a literature review and semi-structured interviews with key experts and urban stakeholders. The results provide an integrated understanding of the proposed system structure that created and maintain the water supply problem in the long-term. Hindrances include knowledge lock-ins and critical dynamics that inhibit the political support to transition towards a drinking water security scenario. This study shows that drinking water supply crisis in the study area and other cities with similar conditions need to be understood as multi-dimensional and from a system perspective, by challenging underlying assumptions and embracing interconnectedness. Key feedback mechanisms are presented in causal loop diagrams, allowing the exploration of higher-order leverage points to reduce existing path-dependencies as one increasingly important research area, and potentially relevant for decision-makers.

Conventionally, the question of Egyptian water security focused on state-centric transboundary hydropolitics within the larger context of the Nile basin. The presented research explores 'water security' beyond this 'state-centric epistemology', typically focusing on a singular scale of hydropolitical analysis. This dissertation examines the water (hydro) politics of transnational land-water investments (LWI) within Egypt and the larger context of the Nile river basin. Adopting a multi-site case study methodology, it critically examines the changing role of the state and the engagement of non-state actors in the silent appropriation of land-water resources through investments in farmlands abroad. The research methodology contextualizes how land acquisitions take several shapes and forms within Egypt (Old-New Lands and New Lands/Mega Projects), as well as in other Nile basin countries (e.g. Sudan). They also manifest land-water-food nexus interdependencies for both; profit and larger strategic objectives, through the formation of 'State-Capital alliances'. Deploying a case study of an international Emirati investor in Egypt, it shows how land-water investments are rooted in a larger socio-political project as part of the state's vision of horizontal expansion and land reclamation, to address its ecological-demographic narrative of crisis. The research also draws linkages between Egyptian water security and transnational investments in other Nile basin countries with a particular focus on the case of Sudan as part of its larger vision of the 'breadbasket of the Arab World'. However, while these State-Capital alliances are rooted in narratives of state modernization, security, and profit, they entail various tensions and trade-offs amongst different resources nexi and actors, thus masking larger questions of social justice and equity. These tensions often reflect the manufacture of abundance and translate into water grabs transcending multiple hydropolitical scales. The thesis argues that the changing role of the "entrepreneurial state" and the engagement of non-state actors in transnational land-water investments manifest a transition from the hydraulic mission towards water security mercantilism. I argue that "water security mercantilism" denotes water grabbing, which overrides the conventional understanding of the hydraulic mission (water control by the state); towards a broader understanding of the role of non-state actors and international investors in accessing water, thus creating their own private resources security nexus. Hence, drawing on development studies, hydropolitics, and political economy scholarship, this dissertation broadens out the analysis of Egyptian water security beyond singular-scale state-centric hydropolitical debates; towards a multi-level polycentric analysis of water security, central to which are the farmers, the investors, and the state itself. This implies that transnational land-water investments not only influence small farmers through the reproduction of scarcity on the local level, but also influence the hydraulic mission of the state on the national level, and the larger Nile basin transboundary hydropolitics.

Balancing water demand and supply in South Africa involves high levels of uncertainty. The Department of Water and Sanitation (DWS) is responsible for making decisions to either increase water supply or decrease water demand so as to ensure that sufficient water is available, when and where it is needed. However, no retrospective analyses of such decisions have been found. One way to assess such decisions is to evaluate the associated costs and benefits thereof. Therefore the primary aim of this study is to evaluate the costs and benefits of selected water supply options, and of the decision-making associated with those options. In order to achieve this purpose, four case studies were analysed within a mixed-methods research paradigm, which used both quantitative and qualitative methods, including unit reference value (URV) analysis, inter- and intra-case analysis and content analysis to examine the success of the decisions made. The four case studies were conducted on the Inyaka, Nandoni, Berg and De Hoop dams and their catchments. Firstly, estimated and actual project costs were compared using unit reference analysis and inter-case analyses. Secondly, the reduction of mean annual runoff (MAR) caused by invasive alien plants (IAPs) and the cost of clearing them in the dam catchments were evaluated using inter-case analyses. Information thus gathered was used together with data from DWS documentation and the results of interviews with ten key specialists, to analyse the decision-making process that led to the decision to build De Hoop Dam (the most recent case study). The rational decision-making model (RDMM) was used as a framework within which to analyse and evaluate this decision-making process. This study has also demonstrated how the RDMM can be used to assess decision-making associated with water supply development. The results of this study show that there is considerable variation of estimated costs (at the time that the decision to build the dam was taken) in relation to the actual costs of building the dams and that Ministers were not put in a position to understand the full long-term costs or the opportunity costs of the proposed dams. Furthermore, the most recent IAP data (2008) shows that the impact on water security by IAPs could not offset the water security resulting from building each of the four dams. However, if IAP management is not continued in these catchments, the projected reduction of MAR by IAPs will compromise water security within 45 years. Given the almost exponential spread and densification of IAPs, together with their long-term impact on MAR and increased costs of controlling them, it is clear that IAP management should have been factored into water supply decision-making from the outset. In the analysis of the decision to build the De Hoop Dam, the results show that while the decision-making process that culminated in the decision to build the dam did not follow the steps of the RDMM, DWS appears to have followed a somewhat similar approach. It was found that while there was a need for the provision of additional water in the Olifants catchment, this need was overstated and the resulting overestimation caused the scale and size of the dam to be larger than it could and probably should have been. Additionally, it appears that DWS‘s decision to build the De Hoop Dam themselves, rather than having it built by the private sector, may have been less than optimal. It is recommended that, in future decision-making, DWS needs to incorporate multiple alternative options into the same solution, and to ensure that decision-makers are put into a position to make informed decisions, including adequate consideration of externalities. Furthermore, DWS needs to employ decision-making models such as the RDMM to facilitate retrospective analyses to improve their institutional knowledge. Keywords: water resources management, dams, invasive alien plants, decision-making, unit reference values, rational decision-making model.

Sanitation is an essential human right for quality of life and health guarantee for every citizen, regardless of their socioeconomic condition. Everyone has the right to have access to an adequate supply of safe and drinking water. Safe water cannot be sustained only by monitoring its quality, it is necessary to guarantee the supply of water on a continuous basis. The Water Safety Plan carries out a systematic assessment that identifies and characterizes the hazards and risks of water supply systems for human consumption, from the source to the point of delivery, aiming at a preventive risk approach to help guarantee the security of water served to the population, establishing control measures and thereby reducing the burden of diseases related to water supply. The Water Safety Plan is an important instrument for identifying possible deficiencies in the water supply system, organizing and structuring it to minimize the chance of incidents. The Environmental Health Technical Chamber (CT-SAM) of the Piracicaba, Capivari and Jundiaí River Basin Committee (PCJ) has been a pioneer in water security, carrying out actions in the municipalities in order to encourage the implementation of Water Safety Plans to ensure the implementation of the Environmental Health Policy, approved within the scope of the PCJ Committee's area of ??activity.

Abstract As an important part of the world energy system, nuclear energy plays an important role in ensuring the security of energy supply in all countries. After decades of development, the use of nuclear energy has been greatly enriched, not only limited to power supply, but also gradually played a role in the fields of Cogeneration, hydropower cogeneration and so on. The increasingly rich application scenarios of nuclear energy also put forward new requirements for the water production process of nuclear power plants. Based on the actual situation of a nuclear project, this paper introduces the water making process of demineralized water for nuclear engineering units and the water making process of boiler make-up water for heating boiler room, points out the problems existing in the original water making process scheme, analyzes the causes of unqualified steam quality of heating boiler, and puts forward practical solutions, The coupling methods of two product water production processes are discussed, and the influence of raw water quality change on the coupling process is analyzed. The coupling scheme of water production process proposed in this paper can realize the simultaneous production of product water with two kinds of water quality in one production line, effectively reduce the engineering cost of water supply facilities, reduce the floor area, ensure the safety of water supply quality, and provide new ideas and references for the multi-purpose utilization of nuclear energy.

The overarching goals for the UK in relation to global water security are to; tackle and reverse growing water insecurity and its consequences caused by depletion and degradation of natural water sources; and address poor water management and increasing demand. To do this, the UK has a well-developed water ‘offer’ that together can help reach the goal of global water security. This note details some of that water offer: UK water leadership: The UK developed the concept of modern sanitation and water supply, with an early example being the Victorian Bazalgette London sewer; Ownership and regulation: The UK has four models of ownership: government department in Northern Ireland, GoCo in Scotland, Mutual in Wales, and private companies in England. But the common thread is strong and clear, regulation to deliver the right outcomes for society; Competition and markets: The UK set up the world’s first water retail markets for business customers, delivering savings and environmental benefits. Similar market mechanisms are being developed for sewage sludge, which will help drive circular economy solutions; Innovation: The UK has a huge number of water tech start-ups and most water companies have labs and pilot schemes to support these fledgling companies. At the same time, the English regulator, Ofwat, has established a huge innovation fund, which along with the Scottish Hydro Nation initiative has made the UK the best place in the world for water innovation and tech.

Serious disruptions and exceptional circumstances for society, that the society tries to prepare for and act in them are at the center of security of supply. Current examples are the COVID pandemic and the ongoing energy crisis for which Finland's security of supply has also been strongly highlighted. Disturbances can also be caused by weather phenomena: in Finland, such examples are windstorms, severe thunderstorms, floods, and droughts, which can, at least in principle, paralyze the society. It is possible to prepare for the impacts of weather phenomena, but the ongoing rapid climate change makes it more complicated. Some of the weather phenomena that cause impacts are fast and violent (e.g. intense thunderstorms) and some occur more slowly (e.g. long heat waves), and climate change affects the phenomena in different ways. In this work, the estimated impacts of climate change on Finland's security of supply were investigated. The starting point was to gain an understanding of which weather phenomena and weather situations are central to security of supply and which sectors of security of supply are the most vulnerable. The work constituted of workshops and expert interviews organized with the National Emergency Supply Agency. In addition to the interviews, the work covered past significant weather situations in Finland that are known to have had significant societal impacts. Information was also extracted from recent literature, especially regarding the vulnerabilities and adaptability of different sectors in Finland. Estimates of the climate change impacts on the identified phenomena were combined with the collected information, resulting in a first understanding of how climate change affects Finland's security of supply. Based on the results, it can be concluded that the impacts of climate change on security of supply are quite complex, especially due to the wide spectrum of weather phenomena and their different impact mechanisms. In addition, the matter becomes more complicated by the fact that there is no clear distinction of what weather phenomenon actually is critical to security of supply and what is not. For example, could the increasing adverse impacts on health care due to the increasingly common heat conditions reach a serious societal disturbance situation at some point, if it is not sufficiently prepared in advance? Another key result is that in terms of security of supply, the direct effects of climate change are very small in Finland compared to many other countries. Although the climate in Finland has already changed considerably and will continue to change in the future, the biggest impacts to security of supply seem to be reflected from elsewhere: the experts of the National Emergency Supply Agency consider the worst situation to be a lack of food, water and habitable living environment in the world, which would also be reflected to Finland. Among the sectors, food/water and energy supply and logistics are perceived as the most vulnerable. The work mainly focused on the direct effects of climate change, i.e. the effects of climate change on the occurrence of various weather phenomena. However, the work also considers to some extent indirect effects, i.e. those reflected from other parts of the world, and transitional effects that result from climate change mitigation measures, especially from the rapid energy transition.
