Although groundwater is a strategic source in volcanic islands, most hydrogeochemical research on this topic has been focused on volcanic activity monitoring, overlooking general hydrogeological aspects. The same applies to one of the most studied volcanoes in the world, Stromboli Island (Italy). Here, we provide a hydrogeological scheme of its coastal aquifer, retrieving inferences about its potential use as a water supply source and for optimizing monitoring protocols for volcanic surveillance. Starting from the hydrogeochemical literature background, we analyzed new data, acquired both for volcano monitoring purposes and during specific surveys. Among these, there were saturated hydraulic conductivity measurements of selected rock samples and precise determinations of water table elevations based on GNSS surveys of wells. We identified a ubiquitous thin lens of brackish water floating on seawater and composed of a variable mixing of marine and meteoric components; inlets of hydrothermal fluids to the aquifer are basically gases, mainly CO2. Based on its hydrogeochemical character, the coastal aquifer of Stromboli could be used as a water supply source after desalinization by reverse osmosis, while the wells located far from the seashore are the most interesting for volcano monitoring, because they are less disturbed by the shallow geochemical noise.

Desalination Plants

Since the world's first land-based desalination plant was established in Australia in 1903, brackish groundwater and seawater desalination became a common water supply technology in many countries around the world. Desalination has proven as a reliable technology in times of drought and/or water scarcity, while in some countries it is an indispensable water supply source on a regular basis. This paper compares and evaluates major desalination leaders in the world (USA, Saudi Arabia, Israel, Australia, and China) with the aim of pointing out similarities and differences that made each of them successful. It also depicts a comprehensive picture of developments, trends and experiences in desalination at the global scale. Establishing desalination plants and ensuring their successful operation is a complex and multifaceted process dependent on capital and operational costs, production capacity, water salinity, geographical location, socio-economic and environmental conditions, and many other factors. The country specific comparison presented in this paper emphasizes the importance of regional planning for successful and sustainable desalination processes in the long term.

Water shortage problems are increasing in many water-deficient areas. Most of the current research on multi-source combined water supplies depends on an overall generalization of regional water supply systems, which are seldom broken down into the detail required to address specific research objectives. This paper proposes the concept of a water treatment and distribution station (water station), and generalizes the water supply system into three modules: water supply source, water station, and water user. Based on a topological diagram of the water network (supply source–station–user), a refined water resource allocation model was established. The model results can display, in detail, the water supply source, water supply quantity, water distribution engineering, and other information of all users in each water distribution area. This makes it possible to carry out a detailed analysis of the supply and demand of users, and to provide suggestions and theoretical guidance for regional water distribution implementation. Tianjin’s water resource allocation was selected as a case study, and a water resource allocation scheme for a multi-source, combined water supply, was simulated and discussed.

Oriented Approach

Iran, like many parts of the world, suffers from water scarcity and is located in one of the most arid regions. This is not only due to the low rates of precipitation received, but also due to the increase in demand on water resources for municipal, agricultural, and industrial uses. Wastewater reuse has proven to be effective and successful in creating a new and reliable water supply. Also, it can meet environmental needs, sustainable development, and a viable economy. There are two strategies for reuse implementation: (1) a future oriented approach allows structured planning within a broader wastewater management master plan and gives the greatest flexibility for reuse; (2) the available effluent quality from existing treatment plants defines the possible reuse option. According to the present situation in Iran, the second strategy is more reliable in preserving the country from absolute scarcity in future. Thus, the objective of this article is to understand the hidden comprehensive potential of reuse in three major categories: agricultural, industrial, and municipal uses, according to the improvement in the Falkenmark indicator.

This chapter explores social movements as a new lens through which to approach grand strategy. Although grand strategists and social movement strategists often view each other as opposites, they have more to learn from each other—and more in common—than either group might think. Within the realm of strategic thought, there has long been significant intellectual overlap between military, political, and social-movement approaches. Far from standing apart from questions of war and peace, stability and instability, conflict and diplomacy, nearly every significant movement for social change has actively engaged these questions, including the real or potential use of violence. Around the world, still more radical movements, many of them at least nominally Marxist in orientation, produced vast literatures on the virtues and vices of revolutionary strategy, as well as the complex task of transforming members and leaders, after victory, from revolutionaries into statesmen. In modern Western democratic societies, social-change strategists tend to favor non-violent methods, but debates rage nonetheless.

I first heard of Bel Prasad Shrestha five years before I met him. An article in the Nepali Times lauded his efforts to establish a water system in the town of Dhulikhel while he was its mayor. I clipped it and set it aside. Fifteen miles from Kathmandu was a municipal utility that put Kathmandu’s to shame. I wanted to know more. Perhaps I saved Bel Prasad for last, expecting the visit to Dhulikhel to be a pleasant excursion—a hopeful encounter that would show me that the break down of urban management I saw every day in Kathmandu was not an inevitable part of development in Nepal. After all those discouraging discussions about Melamchi and about Kathmandu sewage and water supply problems, perhaps I was going to meet a Newar who had a gift for water like his ancient forebears. I went to Dhulikhel the day before May Day, 2010, when Nepal’s Maoists were planning to outdo their usual May Day celebrations with protests all over the city. They were massing their cadres in Kathmandu, ostensibly to pressure the prime minister of another party to resign. On a Friday morning I set out with my friend Ram, a Kathmandu taxi driver who was always available when I needed to venture out on a longer excursion. The shocks on his little white Maruti Suzuki were shot, as they were on most taxis in Kathmandu, but Ram was a good driver who knew all the roads and backroads. Aside from worries about being able to return to the city in the face of demonstrations and roadblocks—or perhaps the complete countrywide shutdown that the Maoists were threatening—Dhulikhel was a green and quiet escape, a fine place to wait out urban riots if any were to materialize. And I found a charming host in Bel Prasad, a unique and now elderly gentleman who had straddled the wide gulf between the rural Nepal of his childhood and the world he had seen in visits to Europe, America, and Japan.

Cerebrovascular and neurodegenerative disorders affect one billion people around the world and result from a combination of genomic, epigenomic, metabolic, and environmental factors. Diagnosis at late stages of disease progression, limited knowledge of gene biomarkers and molecular mechanisms of the pathology, and conventional compounds based on symptomatic rather than mechanistic features, determine the lack of success of current treatments, including current FDA-approved conventional drugs. The epigenetic approach opens new avenues for the detection of early presymptomatic pathological events that would allow the implementation of novel strategies in order to stop or delay the pathological process. The reversibility and potential restoring of epigenetic aberrations along with their potential use as targets for pharmacological and dietary interventions sited the use of epidrugs as potential novel candidates for successful treatments of multifactorial disorders involving neurodegeneration. This manuscript includes a description of the most relevant epigenetic mechanisms involved in the most prevalent neurodegenerative disorders worldwide, as well as the main potential epigenetic-based compounds under investigation for treatment of those disorders and their limitations.
