Strategic Master Plans
2013
The MEDIWAT Project (Sustainable management of environmental issues related to water stress in Mediterranean Islands) aims to provide innovative and sustainable technical, operational and managerial solutions for tackling problems caused by water resources-quality worsening and shortage in the Mediterranean insular context. The project brings together partners from six Mediterranean islands: Sicily, Cyprus, Corsica were considered large islands because of their area and hydrological behavior. Conversely Crete, Malta and Balearic Islands were considered small islands. A detailed analysis of current and future conditions relating to freshwater availability, quality and use has been carried ou…
Essays in applied microeconomics on water resources management
2017
En el contexto actual de creciente escasez de recursos hídricos, el principal objetivo de esta tesis doctoral es contribuir a la mejora de las políticas urbanas de gestión del agua. En un sentido amplio, las conclusiones centrales derivadas de los ensayos incluidos en la misma se pueden agrupar en torno a cuatro aspectos. En concreto, implicaciones para las políticas de demanda, implicaciones para la gobernanza en la gestión urbana del agua, contribuciones metodológicas, y, finalmente, lecciones de política pública para la gestión del agua en España. Resultados sobre políticas de demanda: Como se ha desarrollado de forma más detallada en la introducción, las políticas de demanda, tanto tari…
River Contracts for Innovation in Territorial Governance
2016
Emerged in France in 1980s as agreements oriented to the requalification of rivers and lakes, river contracts represent an important outcome of the decentralization process, developed in Europe in reply to the growing institutional fragmentation. In this scenario, rivers have become a dialectic arena in which the exploitation and management of water resources came to terms with environmental instances, and offered the breeding ground for concerted efforts between policy makers, stakeholders and communities. In this chapter, the analysis is focused on the river contract model and the related set of instruments capable of supporting concerted and participatory management processes both with r…
Resource recovery from sulphate-rich sewage through an innovative anaerobic-based water resource recovery facility (WRRF)
2018
[EN] This research work proposes an innovative water resource recovery facility (WRRF) for the recovery of energy, nutrients and reclaimed water from sewage, which represents a promising approach towards enhanced circular economy scenarios. To this aim, anaerobic technology, microalgae cultivation, and membrane technology were combined in a dedicated platform. The proposed platform produces a high-quality solid- and coliform-free effluent that can be directly discharged to receiving water bodies identified as sensitive areas. Specifically, the content of organic matter, nitrogen and phosphorus in the effluent was 45 mg COD.L-1 , 14.9 mg N.L-1 and 0.5 mg P.L-1 , respectively. Harvested solar…
Analysis of drought and vulnerability in the North Darfur region of Sudan
2018
North Darfur of Sudan is located on the edge of the Sahara Desert and endures frequent droughts due to water shortages and high summer temperatures. Monitoring and understanding drought characteristics are essential for integrated drought risk mitigation and prevetion of land degradation. This study evaluates drought conditions in North Darfur by analyzing the spatiotemporal distribution of drought using three drought indices (Standardized Precipitation Index, Vegetation Condition Index, and Soil Moisture Content Index) and their combined drought index (CDI) from 2004 to 2013. Biophysical and socioeconomic indicators are further used to measure vulnerability to drought risk and its three co…
Business Models and Economic Approaches for Recovering Energy from Wastewater and Fecal Sludge
2015
Universal access to water, sanitation and energy services are key challenges in low income countries. The conventional model of providing water, sanitation and waste disposal as a social service is no longer viable because national authorities lack financial and human resources for operation and maintenance and for addressing the sanitation needs locally. Human excreta and wastewater represent resources that can be used to generate new income and support livelihoods through use as a source of energy. The reduction, removal and reuse of wastes must become financially feasible and economically profitable and yield high returns. This requires innovative and sustainable business models and fina…
Mass and surface energy balance approaches for monitoring water stress in vineyards
2013
Abstract Tree crops are representing one of most widespread agricultural systems in Mediterranean regions, thus contributing in a substantial way to the economy and productivity of primary sectors of the countries interested. Besides the aspects concerning their economical relevance, tree crops like vineyards, olive and orange orchards are also typical elements of the Mediterranean landscape, and their ecological role has been recently revitalised in consideration of their function as carbon sinks for the Kyoto agreement. The environmental and economical sustainability of these agricultural systems in arid and semi-arid zones has to cope with the availability and management of water resourc…
Citizens AND HYdrology (CANDHY) : conceptualizing a transdisciplinary framework for citizen science addressing hydrological challenges
2021
Widely available digital technologies are empowering citizens who are increasingly well informed and involved in numerous water, climate, and environmental challenges. Citizen science can serve many different purposes, from the "pleasure of doing science" to complementing observations, increasing scientific literacy, and supporting collaborative behaviour to solve specific water management problems. Still, procedures on how to incorporate citizens' knowledge effectively to inform policy and decision-making are lagging behind. Moreover, general conceptual frameworks are unavailable, preventing the widespread uptake of citizen science approaches for more participatory cross-sectorial water go…
The Use of Non-Conventional Water Resources as a Means of Adaptation to Drought and Climate Change in Semi-Arid Regions: South-Eastern Spain
2019
Drought is a climatic risk with notable repercussions on water supply systems. The aim of this study is to analyze the principal measures for management and planning implemented during recent decades in south-eastern Spain (Segura River Basin) to respond to drought situations, focusing on the role played by non-conventional water resources (desalination and treated water). The results demonstrate that the study area (despite being one of the driest places of Spain) is less vulnerable to drought than regions with an Atlantic climate and greater availability of water. This has been possible thanks to the integration of non-conventional water resources as a means of adaptation to confront this…
Theoretics and Methodology
2016
Since 2000 in Europe an integrated management framework has been developed to innovate exploitation and safeguard of water resources. In this context the EU Water Framework Directive has identified the hydrographic basin as the optimal territorial unit for promoting new participatory policies, based both on the interaction of stakeholders and the coordination of sectorial instruments. In this scenario, river contracts assumed a strategic role both in addressing these purposes and supporting the dialogue and integration between interests of public and private stakeholders. This chapter illustrates the theoretical and methodological framework, and the comparative approach on which the researc…
