Role of Modeling Uncertainty in the Estimation of Climate and Socioeconomic Impact on River Water Quality
2012
AbstractClimate is one of the most important factors leading to changes in the hydrologic and environmental characteristics of river basins. When considering water quality, the natural factors should be weighed against anthropogenic factors (such as urbanization, increased population, and higher water demand) that may increase or decrease the effect of climatic modifications. Any prediction of future climatic and anthropogenic scenarios is affected by uncertainty and the modelling tools that are used for evaluating their impact on receiving water bodies. The present paper is aimed at investigating the complexity of such analyses and the uncertainty related to future impact predictions based…
The Effect of Hydrology on Soil Erosion
2020
In this Special Issue, we have tried to include manuscripts about soil erosion and degradation processes and the accelerated rates due to hydrological processes and climate change. We considered that the main goal was successfully reached. The new research focused on measurements, modelling, and experiments under field or laboratory conditions developed at different scales (pedon, hillslope, and catchment) were submitted and published. This Special Issue received investigations from different parts of the world such as Ethiopia, Morocco, China, Iran, Italy, Portugal, Greece and Spain, among others. We are happy to see that all papers presented findings characterized as unconventional, provo…
Comparative studies of water governance: a systematic review
2018
[EN] Governance is key to tackling water challenges and transforming water management under the increasing pressures of competing water uses and climate change. Diverse water governance regimes have evolved in different countries and regions to regulate the development and management of water resources and the provision of water services. Scholars and policy analysts have been comparing these water governance regimes to analyze elements and processes, to assess performance, or to draw lessons. Although the number of such studies has increased since the 1980s, no comprehensive synthesis exists. We present such a synthesis by conducting a systematic review of the emerging field of comparative…
Economic and environmental sustainability of submerged anaerobic MBR-based (AnMBR-based) technology as compared to aerobic-based technologies for mod…
2015
[EN] The objective of this study was to assess the economic and environmental sustainability of submerged anaerobic membrane bioreactors (AnMBRs) in comparison with aerobic-based technologies for moderate-/high-loaded urban wastewater (UWW) treatment. To this aim, a combined approach of steady-state performance modelling, life cycle analysis (LCA) and life cycle costing (LCC) was used, in which AnMBR (coupled with an aerobic-based post-treatment) was compared to aerobic membrane bioreactor (AeMBR) and conventional activated sludge (CAS). AnMBR with CAS-based post-treatment for nutrient removal was identified as a sustainable option for moderate-/high-loaded UWW treatment: low energy consump…
Urban sprawl and health outcome associations in sicily
2019
Urban sprawl has several negative impacts on the environment, the economy, and human health. The main objective of this work was to formulate and validate a sprawl/compactness index for Sicilian municipalities and evaluate its association with health outcomes. An ecological study was conducted with 110 municipalities in Sicily, Italy. Principal component analysis was adopted to create the sprawl/compactness Sicilian index, and linear regression analysis was used to evaluate the association between the sprawl index and health outcomes. More variance of the new sprawl index was explained by the working factor, followed by density, surface extension, and land use mix. When validating the index…
Effects of the features of contemporary occidental cities on urban avifauna
2022
Desde los primeros asentamientos humanos permanentes del Holoceno, hace 10 000 años, hasta las ciudades contemporáneas, las aves han cohabitado con los seres humanos. En las últimas décadas la urbanización ha crecido exponencialmente en el planeta y, en 2030, más del 60% de la población mundial vivirá en zonas urbanas. En función de su tolerancia a la urbanización las aves se clasifican en tres categorías: evitadoras, adaptadoras o explotadoras urbanas. Las ciudades occidentales contemporáneas atraen a las aves por la presencia de recursos tróficos abundantes y predecibles, la reducción en la diversidad de depredadores o la provisión de estructuras donde ubicar los nidos, entre otras. Sin e…
Urban Governance in Latvia: Feeling Urban and Thinking Rural
2019
Urbanisation is affecting not only countries with high number of residents but also with small number. The aim of the research is to explore urbanisation and shrinking city tendencies in a country with small number of residents in the context of globalization and urbanisation. The “donut effect” will be explored in the capital city Riga and ten municipalities nearby. The main research question is to what extent can the classical understanding and perception of urbanisation be applied to small societies and countries, and what kind of effects does the urbanisation create in such dynamically developing countries. There are several interdependent problems, such as the new patterns of urban–rur…
The United Citizens Organization: Public-private partnerships in global governance
2020
Abstract Can Public-Private Partnerships be applied to global affairs and governance? This paper reviews the existing relations between public and private global actors. I argue that current international politics is largely an outcome of these relations. Although for the foreseeable future the role of traditional nation-states on the global scene should not be dismissed, they come under the constant pressure of different private actors, particularly of MNCs and NGOs. If this is the case, the question of global responsibility must be raised. It has been the traditional role of governments to stand for such societal values as security and prosperity, and be responsible for their citizens. Wi…
Population Growth and Manufacturing Real Wages in 18th Century England: A Spatial Perspective
2004
We develop a two-region population growth model of economic geography and show that a process of urbanization has a substantial impact on the evolution of manufacturing real wages. Whereas real wages decline as the population increases when the spatial structure of the economy is fixed, they actually rise in the long-run when factors are mobile. Agglomeration may hence be seen as a rational response to declining real wages and provides a new explanation of why manufacturing real wages did not decline prior to the Industrial Revolution in England, despite a historically unprecedented population growth.
