¿Cómo convivir con la escasez de agua? El caso de las Islas Canarias

Escasez de agua no necesariamente significa pobreza, como se dedcice de un análisis de áreas geográficas. Hay países relativamente ricos con escasos recursos hidricos y paises pobres con abundancia de agua dulce. La sociedad humana desarrollada dispone de recursos científicos, tecnicos, económicos, institucionales \; politicos para aáecuar la disponibilidad de agua a la demanda y viceversa, de un modo tendente a la sustentabilidad, siempre y cuando las actividades econornicas se modifiquen convenientemente y esa sustentabilidad sea un objetivo social deseado y participadc. El Archioiélago de Canarias esta en la región érida sahariana, aunque con ireas de pluviosidad relativamente elevada en sus vecientes septentrionales afectadas por la circulación de los vientos alisios y masas atlánticas de aire húmedo. La escasez de agua es algo bien asumido e internalizado en muchas de las áreas insulares canarias, en especial :ras la explosión demográfica del siglo XX. No por ello deja de ser una región europea ae economía aceptable y notablemente rica relativa al entorno geográfico próximo. La consecución de agua dulce es el resultado acumulado de un gran esfuerzo económico e imaginativo secular, con matices diferentes en cada isla y en cada parte de una misma isla. Sin embargo subsisten o han aparecido graves disfunciones a causa de la rapida evolución, arraigo de actividades agricolas no sustentables, debilidad insritucional y escasa participación ciudadana en la ~oliticad el agua a largo plazo, en un ambiente científico y técnico aiin por consolidar. No obstante. los logros en captaciór, de aguas subterraneas sor. espectaculares y el avance en desalinización y reutilización son m ~nyoto rios. ABSTRACT: relatively rich with scarce water resources and poor countries that have plenty of freshwater. A developed human society has scientific, technical, economic, institutional and policy resources to adapt water availability to demand, and vice versa, in a way that tends to sustainabílity. This needs modifying conveniently economic activities and making sustainability a wanted and participated social goal. The Archipelago of the Canaries is placed in the Sanaran dry belt, although there are some areas of relatively high rainfall in the north-facing slopes of the isiands, which intersect the circulation of trade winds and atlantic humid air masses. Water scarciTy is something well assumed and internalised in many of the areas of the Canaries, especially afier the demographic explosion of the XX century. But this does not imply poverty; actually it is an Eu8-opeanr egion wlth acceptable economic leve1 and notably rich respect the nearby geographical area. Freshwater wining is tne accumulated result of secular economic and imaginative efforts, which present differences from island to island and even incide the same island. Nowever some serious malfuncrions remain oí have appeared o'ue 10 the fast evolution, persistence of unsustainable agricultura1 activities 2nd still scarce public participation ir) long-term water policies. This happens in a scientific and iechnical environment which is stil! to be consolidated. However there are spectacular achievements in groundw~ter wining, and there are notorious progress in desalination and water reuse.

Le società pubbliche a partecipazione regionale e locale operanti nei settori dei servizi pubblici locali e dei servizi “strumentali” e quelle con scopo lucrativo: la recente evoluzione legislativa, gli ambiti di attività ed i relativi limiti, le prospettive future.

Con la prima parte, si intende fornire un quadro pressoché esaustivo delle principali disposizioni in materia di società a partecipazione pubblica regionale e locale operanti nel campo dei servizi pubblici locali e della loro interpretazione giurisprudenziale e dottrinale, prendendo le mosse dagli ultimi interventi legislativo. Nella seconda parte, si affronta, invece, il tema dei limiti legislativi alla capacità di azione delle società a partecipazione pubblica e dei connessi dubbi interpretativi, anche alla luce degli orientamenti giurisprudenziali e dottrinali. In particolare, l’analisi riguarda l’art. 13 del decreto”Bersani” e il comma 9 dell’art. 23 bis (ora pedissequamente trasfuso nel comma 33 dell’art. 4 del d.l. n. 138/2011), ossia le principali disposizioni che definiscono, rispettivamente, la capacità di azione delle società (a partecipazione pubblica) strumentali e di quelle operanti nel campo dei servizi pubblici locali titolari di affidamenti diretti (assentiti con modalità diverse dall’evidenza pubblica). Vengono forniti cenni di inquadramento in relazione al cd. procedimento di riordino delle partecipazioni societarie pubbliche previsto dalla legge finanziaria del 2008 (art. 3, commi 27 – 32). Dal combinato disposto delle suddette norme, così come interpretate dalla giurisprudenza costituzionale ed amministrativa, si ricavano, poi, utili indicazioni in ordine alla possibilità, per gli enti pubblici territoriali, di costituire società con scopo meramente lucrativo (ossia, soggetti societari privi del rapporto di strumentalità con gli enti costituenti o partecipanti, chiamati ad operare, in regime di concorrenza, in settori completamente liberalizzati) e società cd. multiutilities (aventi oggetto sociale complesso, la cui attività si estrinseca tanto nel campo dei servizi strumentali, quanto in quello dei servizi pubblici locali), nonché in relazione alla disciplina applicabile all’attività di detti soggetti societari. La finalità ultima del contributo consiste nell'individuazione delle linee guida finalizzate alla classificazione delle società pubbliche in funzione della loro attività.

Internet based health promotion campaign against skin cancer - Results of www.skincheck.ch in Switzerland

Conventional skin cancer prevention programs appeal to limited populations, and the middle aged male population responds less frequently. Our objective was to establish a complementary health promotion campaign tool for skin cancer prevention. Internet-based education, instruction for self assessment and teledermatological evaluation of skin lesions by an expert commission of dermatologists was used. Compliance and clinical diagnosis was assessed in a subgroup. 12,000 users visited the educational website. There was strong interest among the middle aged male population (53% (N = 262): male; mean age: 42). 28.5% of examined lesions (N = 494) were considered suspicious. Email requests, sent to the group whose lesions where considered suspicious, were answered by 46.0% of females (N = 29) and 59.7% of males (N = 46) with a female distribution predominantly in younger ages (52.6% of females with known age: < 30 years). Males were predominantly represented over 30 years (86.2% of all males). According to user's declarations, at least 8 (8.5%) malignant lesions (1 melanoma in situ, 1 squamous cell carcinoma, 4 basal cell carcinomas, 2 malignant lesions without declared diagnosis) were finally diagnosed by physicians. We conclude that internet-based, interactive, educational programs, in addition to existing health promotion campaigns, can enhance public participation in the middle aged male population in skin cancer prevention.

Fostering sustainable urban development in Nakuru, Kenya Rift Valley

The town of Nakuru—Kenya's fourth largest town—lies in a unique setting in the Great Rift Valley. Recent developments on the Menengai Crater, the Mau Escarpment, and the Bahati Highlands exemplify the impacts of poorly planned urban growth on mountain ecosystems. The Nakuru Local Urban Observatory (LUO) project was initiated by the Municipal Council of Nakuru in January 2003, in collaboration with the Centre for Development and Environment (CDE) of the University of Berne and the Intermediate Technology Development Group (ITDG), and with funding from the Swiss Agency for Development and Cooperation (SDC). The project aims to provide a framework for sustainable urban development practices by building technical skills and improving participation by local stakeholders in decision-making processes. The potentials of information technology (IT) are being tapped to provide up-to-date information to decision-makers and democratize access to information, in order to improve public participation. The overall objective is to find ways of achieving better urban management in order to mitigate non-sustainable development trends in the town and its surroundings.

Participatory modeling for sustainable development in water and agrarian systems: potential and limits of stakeholder involvement

Public participation is increasingly advocated as a necessary feature of natural resources management. The EU Water Framework Directive (WFD) is such an example, as it prescribes participatory processes as necessary features in basin management plans (EC 2000). The rationale behind this mandate is that involving interest groups ideally yields higher-quality decisions, which are arguably more likely to meet public acceptance (Pahl-Wostl, 2006). Furthermore, failing to involve stakeholders in policy-making might hamper the implementation of management initiatives, as controversial decisions can lead pressure lobbies to generate public opposition (Giordano et al. 2005, Mouratiadou and Moran 2007).

Indicadores de sostenibilidad de la gestión integral de las aguas de lluvia en los entornos urbanos : aplicación a la ciudad de Zaragoza

En un contexto de rápido crecimiento de la población urbana y de cambio climático global, la consecución de un modelo de desarrollo sostenible pasa inevitablemente por construir ciudades más sostenibles. Basado en una intensiva impermeabilización de los suelos, el modelo actual de desarrollo urbano modifica profundamente el ciclo natural del agua en las ciudades. La drástica reducción de la capacidad de infiltración del terreno hace que gran parte de la precipitación se transforme en escorrentía superficial, que se concentra rápidamente originando grandes caudales punta. Además, el lavado de las superficies urbanas aporta altas cargas de contaminación a la escorrentía que producen importantes impactos en los medios receptores. Esta realidad motiva la realización de la presente tesis doctoral cuyo objetivo general es contribuir a la consecución de ciudades sostenibles a través de la gestión integral de las aguas de lluvia en los entornos urbanos. Con el objetivo prioritario de minimizar los riesgos de inundación, el enfoque convencional del drenaje urbano desarrolló las primeras soluciones en relación a los caudales punta, centralizando su gestión en el sistema de saneamiento e incorporando la escorrentía al mismo tan rápido como fuera posible. Pero en episodios de lluvias intensas la sobrecarga tanto hidráulica como de contaminación del sistema provoca un incremento de la vulnerabilidad de la población a las inundaciones, una falta de garantía de salud pública y graves impactos sobre los medios receptores. La aprobación en 1987 del CleanWaterAct en Estados Unidos, en el que se reconoció por primera vez el problema de la contaminación aportada por la escorrentía urbana, fue el punto de partida de un nuevo enfoque que promueve un conjunto de técnicas de drenaje que integran aspectos como cantidad de agua, calidad de agua y servicio a la sociedad. Estas técnicas, conocidas como Sistemas de Drenaje Sostenible (SUDS), son consideradas como las técnicas más apropiadas para gestionar los riesgos resultantes de la escorrentía urbana así como para contribuir a la mejora medioambiental de la cuenca y de los ecosistemas receptores. La experiencia internacional apunta a que la efectiva incorporación de los SUDS como sistemas habituales en el desarrollo urbano debe basarse en tres elementos clave: El desarrollo de un marco normativo, la aplicación de instrumentos económicos y la participación ciudadana activa en el proceso. Además se identifica como una de las líneas estratégicas para avanzar en la resolución de la problemática el desarrollo y aplicación de metodologías que apoyen el proceso de toma de decisiones basadas en indicadores cuantificables. Convergiendo con esta línea estratégica la presente tesis doctoral define unos indicadores de sostenibilidad focalizados en una temática no desarrollada hasta el momento, la gestión integral de las aguas de lluvia. Para ello, se aplica el marco analítico Presión-Estado–Respuesta bajo un enfoque que rebasa el sistema de saneamiento, enmarcando la gestión de las aguas de lluvia en las múltiples y complejas interrelaciones del sistema urbano. Así se determinan indicadores de presión, de estado y de respuesta para cada elemento del sistema urbano (Medio Receptor – Cuenca Urbana – Sistema de Saneamiento), definiendo para cada indicador el objetivo específico, la unidad de medición, la tendencia deseada de evolución y la periodicidad de seguimiento recomendada. La validez de la metodología propuesta se comprueba en el estudio de caso de la ciudad de Zaragoza. La determinación de los indicadores permite realizar un diagnóstico y definir unas líneas estratégicas de actuación que contemplan mejoras no sólo en el sistema de saneamiento y drenaje urbano, sino también en el marco normativo, urbanístico, económico, social y ambiental. Finalmente, se concluye que la integración de la gestión de las aguas de lluvia en las políticas de ordenación del territorio, el desarrollo de mecanismos de coordinación institucional, la mejora del marco normativo y la aplicación de instrumentos económicos son elementos clave para la gestión integral de las aguas de lluvia y el consecuente desarrollo de ciudades más sostenibles en España. In a context of rapid urbanization and global climate change, coping with sustainable development challenges requires the development of sustainable cities. Based on an intensive soil permeability reduction, the current development model deeply modifies the natural water cycle in the urban environment. Reduction of soil infiltration capacity turns most of the rainwater into surface runoff, rapidly leading to heavy peak flows which are highly contaminated due to the flushing of the urban surface. This is the central motivation for this thesis, which aspires to contribute to the attainment of more sustainable cities through an integrated management of rainwater in urban environments. With the main objective of minimizing floods, the conventional approach of drainage systems focused on peak flows, centralizing their management on the sewage system and incorporating flows as fast as possible. But during heavy rains the hydraulic and contamination overcharge of the sewage system leads to an increase in the vulnerability of the population, in regards to floods and lack of public health, as well as to severe impacts in receiving waters. In 1987, the United States’Clean Water Act Declaration, which firstly recognized the problem of runoff contamination, was the starting point of a new approach that promotes a set of techniques known as Sustainable Drainage Systems (SUDS)that integrates issues such as quantity of water, quality of water and service to society. SUDS are considered the most suitable set of techniques to manage the risks resulting from urban runoff, as well as to contribute to the environmental enhancement of urban basins and of the aquatic ecosystems. International experience points out that the effective adoption of SUDS as usual systems in urban development must be based on three key elements: The enhancement of the legal frame, the application of economic tools and the active public participation throughout the process. Additionally, one of the strategic actions to advance in the resolution of the problem is the development and application of methodologies based in measurable indicators that support the decision making process. In that line, this thesis defines a set of sustainability indicators focused in integrated management of rainwater. To that end, the present document applies the analytical frame Pressure – State – Response under an approach that goes beyond the sewage system and considers the multiple and complex interrelations within urban systems. Thus, for the three basic elements that interact in the issue (Receiving Water Bodies – Urban Basin – Sewage System) a set of Pressure – State – Response indicators are proposed, and the specific aim, the measurement unit, the desired evolution trend and the regularity of monitoring are defined for each of the indicators. The application of the proposed indicators to the case study of the city of Zaragoza acknowledged their suitability for the definition of lines of action that encompass not only the enhancement of the performance of sewage and drainage systems during rain events, but also the legal, urban, economic, social and environmental framework. Finally, this thesis concludes that the inclusion of urban rainwater management issues in the definition of regional planning policies, the development of mechanisms to attain an effective institutional coordination, the enhancement of the legal framework and the application of economic tools are key elements in order to achieve an integrated rainwater management and the subsequent sustainability of urban development in Spain.

EIA-RIMA insuficiente como avaliação de impactos ambientais enquanto busca de sustentabilidade urbana: o caso de São Sebastião

O presente trabalho comprova que o atual instrumento EIA-RIMA - Estudo de Impacto Ambiental e seu respectivo Relatório de Impacto Ambiental, é insuficiente enquanto busca de sustentabilidade urbana no Litoral Norte do Estado de São Paulo, especificamente no município de São Sebastião. O método de analise dos EIA-RIMA sempre enfatizam os ganhos econômicos e atenuam os impactos negativos, apesar das fragilidades naturais, estruturais e restrições legais incidentes. A tese comprova que os instrumentos utilizados no âmbito do processo de licenciamento ambiental dos empreendimentos, como a ampliação do porto comercial de São Sebastião, estão pouco comprometidos com o real desenvolvimento sustentável da cidade e região. As especificidades geográficas, sobretudo as facilidades de interface do território terrestre com o marítimo, proporcionadas pelas características naturais do Canal de São Sebastião, sempre ofereceram condições privilegiadas para o abrigo de embarcações, característica decisiva na escolha do lugar como cidade portuária, vinculada aos mais importantes ciclos econômicos do país. Agora, em 2015, está prestes a entrar em um novo ciclo, principalmente com a ampliação do porto comercial, duplicação da rodovia dos Tamoios e da SP-055 e a exploração da camada pré-sal na Bacia de Santos. A região já apresenta todos os problemas de uma ocupação acelerada em um território ambientalmente frágil, localizado em estreita faixa litorânea, composta de um lado pela Serra do Mar e do outro pelo Oceano Atlântico. Se não houver um planejamento urbano e regional que considere as características e capacidade de suporte deste território, a zona costeira entrará em colapso. Saber dosar o uso de suas potencialidades sem esgotá-las será o desafio de nossa geração. Os Estudos de Impactos Ambientais precisam ser aperfeiçoados para que ações mitigadoras alcancem muito mais do que o mínimo, alinhadas a investimentos, tecnologias inovadoras, infraestruturas necessárias e obrigatórias que sejam pensadas de maneira conjunta e cumulativa nas diversas esferas do poder, com efetiva participação pública, caso contrário, o crescente interesse econômico e político tenderá à destruição irreversível do patrimônio histórico e natural deste território. O EIA está se transformando em um poderoso instrumento político de ordenamento territorial que acaba por definir critérios e parâmetros de uso e ocupação, desempenhando uma função que não lhe compete, além de aprofundar o desencontro entre uma vida urbana de qualidade e um ambiente equilibrado em nome do desenvolvimento econômico e a serviço dos interesses privados.

CERCLA: A Case Study of Local Government Involvement in the Decision-Making Process in Colorado

The Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) of 1980, and the Superfund Amendments and Reauthorization Act (SARA) of 1986 strengthen roles of the community in the CERCLA process. Many layers of bureaucracy and the complexity of regulations make the implementation and enforcement of environmental policy a burdensome process. Local government, the public and private corporations have a critical role in the CERCLA decision-making process by implementing a comprehensive public participation process. This paper examines a case study in which a local Colorado health department implemented a successful public participation process in order to positively affect the remediation decision-making process.

Utilization of ADR Concepts to Bridge the Gap Between the Extractive Industry and Environmental Interests: An Anticipatory Cooperative Effort (ACE)

The extractive industry, more than any other sector of the economy, often finds itself mired in conflicts with various environmental and community interests. As traditional legal avenues of resolution gave way to the collaborative ideas of alternative dispute resolution, the outcomes, especially the relational outcomes, were less than desirable. This capstone project proposes that an Anticipatory Cooperative Effort (ACE) can help to bridge the gap between industry and environmental interests by encouraging a pro-active and pre-emptive engagement. The point of the ACE concept is not that it defines a new set of principles so much as it repositions where established ADR principles are entertained.

Reverse Vending Machines: A Potential Solution for the Florida Plastic Waste Management Challenge

The waste of plastic beverage bottles creates environmental problems and takes up a large volume of landfill space. The high rate of consumption of plastics in the State of Florida is challenging the disposal capacity of waste authorities. The lack of the reverse vending machines in the State of Florida, including applicable scientific or technical literature represented an opportunity for this research to discuss the applicability of this equipment as a potential solution for the management of the plastic waste in Florida. With this research document, I will propose a recycling system for plastic bottles made with PET based on the implementation of reverse vending machines, stressing the importance of the creation of policies that promote recycling and public participation.
