This report examines water supply planning issues in San Antonio, Texas. San Antonio is unique among large cities in the United States in that it relies almost exclusively on a single source, the Edwards Aquifer, for its water supply. Because San Antonio’s water demand is projected to outgrow the Aquifer’s capacity, the city must consider other options to extend and augment its current water supply. After describing the hydrogeology and water supply history of San Antonio, this report explains the multitiered water planning structure and current and future water needs for the city. It then studies and evaluates three short-to-mid term water supply options. By continuing to develop its already successful water conservation programs and water reclamation system, San Antonio can delay the need for more costly and environmentally impactful water supply options down the road, and wisely manage the resources it already draws from. / text

The construction of large dams has become a contentious issue throughout the world. Environmentalists, human rights activists, NGOs, academics and local communities have all contributed to the debate. On the one hand, proponents have highlighted the role of dams in alleviating poverty, improving the quality of life of communities, and their positive impact on local and national economies. Opponents of large dams have argued that the negative impacts on the environment and local communities outweigh any perceived benefits. Methods for assessing the environmental impact of large projects have been used since the 1970's. By 1988 most of Europe had adopted methods such as environmental impact assessment for evaluating the impact of proposed projects. These procedures aim to inform decision makers and authorities of the potential impact that a proposed project may have. World financial institutions, such as the World Bank, have also adopted the use of these assessment methods as part of their evaluation of projects that are seeking funding. This research establishes the environmental standards and requirements that were in place internationally, nationally and regionally, during the planning, design and implementation of Phase 1A and Phase 1B of the Lesotho Highlands Water Project. The products of the environmental investigations during successive phases of the project (1986-1999) are assessed to establish whether the parties involved conform to these standards. In addition, the research highlights affected communities' experience of the project implementation, as well as the impact of the project on their lives. The research suggests that in the early phases of the Lesotho Highlands Water Project (feasibility and Phase 1A), studies failed to meet environmental assessment standards and requirements, Studies undertaken during Phase 1B represent a considerable improvement and conform more closely to World Bank standards. Although the participation of interested and affected parties has improved, there still appear to be areas of major concern to affected communities. The study highlights the need for greater transparency during the assessment phase of projects, and in particular, more effective involvement of the local communities. Future environmental assessments of this nature are likely to be subject to more stringent requirements including the systematic assessment and quantification of downstream impacts and the incorporation of the costs of all impacts in the project costs. Further phases of the Lesotho Highlands Water Project, will therefore need to demonstrate environmental sustainability in the long term. / Thesis (M.Sc.)-University of Natal, Pietermaritzburg, 2000.

Conselho Nacional de Desenvolvimento Científico e Tecnológico / O alto crescimento populacional tem desencadeado uma elevada ocupação das áreas urbanas com a expansão de edificações e estradas causando alterações no meio ambiente com a consequente minimização das áreas verdes e da infiltração de água no solo. Estes fenômenos acarretam problemas como enxurradas, inundações, aumento da temperatura local e diminuição da biodiversidade com inúmeros efeitos adversos, tanto econômicos quanto ambientais e sociais. Uma das alternativas para minimizar estes problemas é a construção de telhados verdes, que tem como uma das principais funções retardar o escoamento devido ao aumento da infiltração e retenção da água das chuvas atenuando o efeito avassalador das enchentes e das zonas de calor, principalmente em climas muito quentes, além de colaborar para recuperação de ecossistemas, através do replantio de mudas. Este projeto faz parte de um conjunto de ações integradas de cidadania e inclusão social na região hidrográfica da baixada de Jacarepaguá, especificamente envolvendo a Comunidade da Vila Cascatinha, em Vargem Grande, a fim de gerar subsídios para políticas públicas em áreas de assentamentos informais, integrado ao projeto HIDROCIDADES (CNPq, FAPERJ, FINEP), que visa a conservação da água em meios urbanos e periurbanos associado à cidadania, inclusão social e melhoria da qualidade de vida nas grandes cidades. Este trabalho utiliza uma tecnologia adaptada dos telhados verdes para edificação popular (telhado de fibrocimento) muito comum no Brasil, com o objetivo de verificar uma espécie com potencial de geração de renda (visando o social) de ecossistema regionais como restinga, em edificação; analisar o crescimento e biomassa da espécie de restinga cultivada em telhados; e avaliar qualidades das mídias em função do plantio em análise de armazenamento (retenção) de água no solo. A partir da metodologia empregada na implantação dos telhados verdes em habitações populares, os resultados obtidos são desenvolvimento da espécie Ipomoea pes caprae Brasiliensis, em três tipos de mídias de crescimento e também eficiência dessas mídias no escoamento superficial. Observou-se retenção de 69,24L de água para o bagaço de cana de açúcar e 64,7L para a fibra de coco. E foi observado também um retardo da ocorrência do pico de até 14 minutos no telhado vegetado em relação ao telhado controle (convencional). / The high rates of population growth has led to a dense occupancy of periferic urban areas with buildings and roads. This has caused changes in the environment with the consequent minimization of green areas and water infiltration into the soil. These phenomena have been favoring problems such as landslides, floods, temperature increase and local biodiversity decreasing with numerous adverse effects, both social-economic, and environmental. One alternative to minimize these problems is the construction of green roofs, which has as one of its main functions increase infiltration and retention of rainwater, alleviating the effects of floods and heat zones, especially in very hot climates, and contribute to ecosystem restoration. This research is part of a set of integrated actions of citizenship and social inclusion in the lowland of Jacarepaguá river basin, specifically involving the Community Vila Cascatinha in Vargem Grande, in order to generate support for public policy in areas of informal settlements, integrated HIDROCIDADES Project (CNPq / FAPERJ / FINEP), which aims to conserve water in urban and peri-urban areas associated with citizenship, social inclusion and the improvement of quality of life in big cities. This work uses an adapted technology for planting on roof tops of social interest habitations (fibercement tiles), very common in Brazil, aiming to verify a restinga local ecosystem species with potential for income generation increase (foccus on the social), as well as environmental compensation. It was analyzed the growth and biomass generation of the Ipomoea pes caprae Brasiliensis cultivated on roof top and assessed qualities of the growth media and its retention capacities. Retention of 69.24 liters of water on sugar cane bagasse and 64.7 L on coconut fiber applied as growth medias were observed. It was also observed a delay in the occurrence of the peak-flow of up to 14 minutes on the planted roof in comparison to the convetional roof top of fibercement tiles (non-planted).

Uppsatsens syfte är att undersöka om kommuner i Mälarregionen drabbades av låga yt- och grundvattennivåer under sommaren 2017, hur situationen hanterades, deras dagliga arbete med vattenfrågor och om handlingsplaner fanns för låga nivåer före 2017. Vi vill även se hur kommunerna ställer sig till klimatförändringar samt sammanställa vilka roller och ansvar som olika myndigheter har när det kommer till vattenförsörjning. Arbetets undersökningsområde begränsades till 39 kommuner i fyra län: Södermanlands, Upplands, Västmanlands och Örebro län. För att besvara syftet skickades en enkät ut till kommunerna och intervjuer genomfördes med två av kommunerna. En litteraturstudie genomfördes för att kunna besvara ansvarsfördelningen mellan olika myndigheter. Enkäten besvarades av 26 kommuner. Det viktigaste resultat var att kommunerna, trots vattennivåer under det normala, inte upplevde vattenbrist i den omfattningen som vi trott. Fem kommuner angav att de drabbades av vattenbrist. Den huvudsakliga åtgärden som infördes var bevattningsförbud. Från enkäten framkom att det i stor utsträckning saknats handlingsplaner för att hantera en situation med vattenbrist innan 2017. Majoriteten av kommunerna tror att deras vattenförsörjning kan påverkas av klimatförändringar, men bara 14 angav att de har en handlingsplan för det. Resultatet som framkom från intervjuerna gällde främst processen för införandet av skyddsområden. Även i litteraturstudien framkom det att arbetet med vattenskyddsområden inte går i den takt som är nödvändig för att nå målen förhållbar och långsiktig dricksvattenförsörjning. / The aim of this paper is to examine how municipalities in the Mälar region of Sweden were affected by the low surface and groundwater levels in the summer of 2017, how municipalities handled the situation, how they work with water related questions in their daily work and whether they had an action plan for dealing with shortage of water prior to 2017. Lastly, we also aim to compile the roles and responsibilities for different authorities when it comes to water supply. The area of study was limited to 39 municipalities in four counties: Södermanlands, Upplands, Västmanlands and Örebro county. To answer the aim, a survey was sent out to all municipalities and interviews were done with two of the municipalities. A literature study was done in order to answer the division of responsibilities between different authorities. The survey was answered by 26 municipalities. The main result we got from the survey was that even though the water levels were below normal, the municipalities didn’t experience water shortages in the extent we had expected. Five municipalities indicated that they had been affected by the water shortages. The main measure that were done was the irrigation ban. From the survey it was found that most of the municipalities were lacking action plans to deal with a water shortage situation before2017. The majority of the municipalities believe that their water supply can be affected by climate change, but only 14 indicated that they have an action plan for it. The results obtained from our interviews primarily marks the division of responsibilities for water conservation areas. As conducted from the literature study, the processes to constitute water conservation areas does not seem to be smooth and quick enough to meet the goals of sustainable and long-term water supply.

Essa Tese apresenta um framework para implementação de redesenho urbanístico de assentamentos informais no contexto da corrente atual do planejamento urbano integrado aos dos recursos hídricos, focado na conservação da água e na sustentabilidade ambiental. Entre outros, sugere-se a implantação do desenho urbanístico de forma participativa e colaborativa. Apresenta-se, de forma ilustrativa proposta de redesenho para a comunidade da Vila Cascatinha localizada na Baixada de Jacarepaguá, Rio de Janeiro, região de expansão da cidade, que serviu como objeto de estudo. A área do assentamento é de indefinição fundiária e atualmente é ocupada por aproximadamente 900 famílias. O framework baseia-se na corrente do urbanismo de baixo impacto, sobretudo do Low Impact Urban Design and Devolopment (LIUDD). Os dispositivos são implantados na escala local, de forma descentralizada para a conservação e manejo das águas pluviais no meio urbano. A pesquisa está inserida no Projeto HIDROCIDADES, desenvolvido dentro dos princícpios da metodologia de pesquisa-ação proposta por Thiollent. Foi realizado trabalho de campo e entrevistas guiadas, tendo sido identificado um percentual expressivo de moradores descendentes de antigos pequenos produtores agrícolas. Na pesquisa, moradores elencaram os principais problemas do assentamento. Além disso, foram diagnosticadas potencialidades dos moradores, dentro do conceito de Tecnologia Social. A prospecção entre os moradores também procurou verificar, em um contexto de colaboração, o conhecimento e a aderência dos moradores às estruturas urbanísticas praticadas no contexto da corrente Desenho Urbano de Baixo Impacto. Ao final deste processo foi gerada proposta de reurbanização sustentável do assentamento estudado, bem como proposta de moradias coletivas sustentáveis. Guardando as devidas especificidades, espera-se que a proposta apresentada possa ser aplicada a outros assentamentos de paisagem similar. / This thesis, associated to HIDROCIDADES Project, is also part of the FINEP Maplu-2 network research. It presents a framework for the implementation of the urban redesign of informal settlements, in accordance with present day urban planning tendency that integrates water resources into urban planning, focusing on water conservation, environmental sustainability and environmental education. This framework is based on the principles of Low Impact Urban Design and Devolopment (LIUDD New Zealand), Low Impact Design (LID EUA), Water Sustainable Urban Design (WSUD- Australia) and Sustainable Urban Drainage System (SUDS UK). The LIUDD puts forward the application of local and decentralized devices for urban drainage and superficial outflow, such as harvesting and profiting from rainwater, green roofs, park implantations and rainwater beds infiltration, adoption of permeable areas in the public sidewalks and roads, among others. The Community of Vila Cascatinha, situated in the lowland grounds of Jacarepaguá, in Rio de Janeiro, was adopted as a case study. In 2006 the Community had 900 inhabitants, who through field work and guided interviews were identified as descendants of small agricultural producers. Nowadays, the area, which is part of the expansion of the city, will be developed to locate important sports infrastructure for the 2016 Olympic Games, (therefore the relevance of this urban redesign proposal). During the interviews several problems were mentioned by the locals and among the most serious ones were the presence of rats and the occurrence of recurring floods. It was also possible to identify how familiar and sensitive the dwellers were to the some of the practices presented in the LIUDD context. The ultimate aim of the interviews was to elaborate an action plan, as described by Thiollent, for the sustainable urban redesign of the settlement under study, as well as a proposal for sustainable community dwellings, so as to minimize the effects of floods derived from the excessive waterproofed soil. Despite the specificities of the proposal, it is believed that it can be applied to other settlements in similar conditions.

In general, it s possible to verify that they do not attend even the word semantic meaning. The no existence of a coordinated set of action aiming at ampler results makes rainwater plumbing system unconcerned with the surrounding area, not composing harmonically with the urban site in particular, and the environment as a general form. Generally, designers expect only rainwater goes toward out of the site, and that is a good result of a good system. Due the lack of attention to the impact that generates and does harm to society, they ignore its potential as instrument of water building conservation. They do not assess correctly its capacity as a source of supply of so expensive and scarce water, according with its necessities, conveniences or limitations that can exist. Therefore, the goal of this study is to propose a new function for the rainwater plumbing system, in special for Ribeirão Preto municipal school buildings, becoming it from a passive to an active system of environment protection. With a proper and molded conception for this new proposal, the system must contemplate the aspects related to the reduction of the impacts caused by the civil construction activities on urban sites, its preservation and providing environment education for people and also, as an worthy water building management tool. / Os atuais projetos dos sistemas prediais de água pluvial são em sua grande maioria, extremamente simples, apresentando uma única e exclusiva preocupação: a transferência da precipitação do local onde ocorre para o sistema público de drenagem, constituído por sarjetas, galerias e por fim, os córregos e rios. Verifica-se que, em geral, não atendem nem ao sentido semântico da palavra sistema. A inexistência de um conjunto coordenado de ações visando um resultado mais amplo faz com que o sistema predial de água pluvial se dissocie de seu entorno, sem se compor harmônicamente com o meio urbano em particular, e o meio natural de uma forma geral. Na concepção atual de seus projetistas, o simples encaminhamento destas águas para fora da edificação é o resultado esperado de um bom sistema. Alheios ao impacto que gera e que penaliza a socidade, passam ao largo de seu potencial como instrumento de conservação de água nas edificações. Ignoram sua capacidade de suprir as mesmas com tão caro e cada vez mais escasso recurso, de acordo com as necessidades, conveniências ou limitações que possam existir. Portanto, o objetivo deste trabalho consiste na proposição de uma nova função para o sistema predial de água pluvial, em especial nas escolas muncipais de Ribeirão Preto, transformando-o de um sistema passivo de captação e drenagem em um sistema ativo de conservação ambiental. Com uma concepção própria e moldada para esta nova proposta, o sistema deve contemplar os aspectos relacionados à redução dos impactos causados pela ocupação do solo no meio urbano, à preservação e educação ambiental e também, à gestão da oferta de água nas edificações.

Water scarcity and water contamination are persistent problems facing large numbers of people in India. In order to combat scarcity, the Indian Federal government designated 2016 to be the Year of Water Conservation. In order to prepare for the success of this initiative, different management strategies and awareness campaigns began in 2015. Critics have generally responded favourably to these shifts in water management because conservation is considered a benevolent and even environmentally-friendly, or “green” process that can successfully combat water scarcity. However, these initiatives often change the ways in which people access water based upon new governing mentalities. The governing mentality most strongly underpinning these initiatives is based on a neoliberal rationality, which is generally admonished by academics and activists due to the production of uneven socio-economic landscapes under neoliberal economics. Similarly, in an effort to combat water contamination, governing authorities have initiated programs and policies to ensure that safe water is provided for citizens. However, this too has often been influenced by neoliberal governing mentalities. In order to analyze these shifts, this dissertation takes a closer look at the narratives of water conservation, water scarcity, and water contamination using a political ecology framework in three states in North Western India: Punjab, Himachal Pradesh, and Haryana. The following manuscript style thesis consists of five independent papers, plus an introduction and conclusion, linked thematically through the discussion and analyses of the shifting nature of the hydro-social cycle under the pressure of various neoliberal reforms and processes initiated by federal and state governing authorities in North Western India. Having independent papers lends itself to a more nuanced discussion of the ways in which neoliberal water management strategies are lived-out in various communities. Neoliberalism is not an overarching hegemonic project or phenomenon, and as such the discourses of neoliberalism have had different consequences for different communities and populations. As such, this thesis highlights the ways in which the shifting hydro-social cycle has changed gender-related activities of water collection, the ways in which contamination is a form of slow violence, the ways in which defacto public-private partnerships operate in water scarce urban centres, and the ways in which discourses of conservation can be misleading and even manufactured. / Graduate / 2019-05-23

Magister Scientiae (Integrated Water Resource Management) / The water resources management regime has shifted from one focusing almost exclusively on augmenting supply to one where ensuring access, equity and sustainability are an integral part of the process. A growing demand for water and the fact that the amount of fresh water is constant raises the impression of water scarcity will occur. Indications are that the notion of access to water for basic needs as well as access to productive water underpins perceptions of scarcity. This thesis interrogated perceptions of scarcity in a small rural community in order to understand the role water can play in developing sustainable livelihoods. / South Africa
