The role of soils in regulation and provision of blue and green water
2021
The United Nations Sustainable Development Goal 6 aims for clean water and sanitation for all by 2030, through eight subgoals dealing with four themes: (i) water quantity and availability, (ii) water quality, (iii) finding sustainable solutions and (iv) policy and governance. In this opinion paper, we assess how soils and associated land and water management can help achieve this goal, considering soils at two scales: local soil health and healthy landscapes. The merging of these two viewpoints shows the interlinked importance of the two scales. Soil health reflects the capacity of a soil to provide ecosystem services at a specific location, taking into account local climate and soil condit…
Energy, water and environmental balance of a complex water supply system
2015
The present paper describes the analysis of water and energy balance in a complex urban water supply system. The analysis was carried out employing Life Cycle Analysis (LCA) methodologies. The LCA approach was integrated with the analysis of the system energy and water balance. For a real size water supply system, based on the results of the individual LCAs, the current baseline was constructed highlighting the water, energy and environmental (in terms of CO2eq emissions in the atmosphere) costs of supplied water. Then, three different mitigation measures have been evaluated: the first is based on energy production by installation of photovoltaic systems; the second is based on energy recov…
Environmental assessment of the Sibiu County, Romania: proposal for sewage sludge and OFMSW management
2017
The aim of the work is to assess current solid waste management (SWM) and wastewater treatment (WWT) in the county of Sibiu, Romania. Sibiu is a region where industrialization and tourism are spreading constantly, while pollution monitoring and the introduction of circular economy (CE) principles are still lacking. The environmental issues are mostly due to the absence of reliable sanitation systems, in particular for what concerns sewage sludge treatment. Moreover, Organic fraction from selective collection of municipal solid waste is still missing, since it is disposed of directly to landfill, increasing environmental pollution and contributing considerably to global warming. As a result,…
Emerging Standards and the Hybrid Model for Organizing Scientific Events During and After The COVID-19 Pandemic
2020
AbstractSince the beginning of 2020, the coronavirus disease (COVID-19) pandemic has dramatically influenced almost every aspect of human life. Activities requiring human gatherings have either been postponed, canceled, or held completely virtually. To supplement lack of in-person contact, people have increasingly turned to virtual settings online, advantages of which include increased inclusivity and accessibility and a reduced carbon footprint. However, emerging online technologies cannot fully replace in-person scientific events. In-person meetings are not susceptible to poor Internet connectivity problems, and they provide novel opportunities for socialization, creating new collaboratio…
Mapping a-priori defined plant associations using remotely sensed vegetation characteristics
2014
Abstract Incorporation of a priori defined plant associations into remote sensing products is a major challenge that has only recently been confronted by the remote sensing community. We present an approach to map the spatial distribution of such associations by using plant indicator values (IVs) for salinity, moisture and nutrients as an intermediate between spectral reflectance and association occurrences. For a 12 km 2 study site in the Netherlands, the relations between observed IVs at local vegetation plots and visible and near-infrared (VNIR) and short-wave infrared (SWIR) airborne reflectance data were modelled using Gaussian Process Regression (GPR) (R 2 0.73, 0.64 and 0.76 for sali…
Chronicles of rice, mosquitoes and malaria in Spain: the case of the province of Valencia (18th-20th centuries)
2010
This study analyzes the situation of the rice fields in the Valencia province (Eastern Spain) during the centuries XVIII-XX. This area, together with the region of Campo Arañuelo (Western Spain), is one of the territories with highest malaria prevalence during the Spain's Modern History. Medical, demographic, social, economic and legal issues related with the problematic of the rice during this epoch are also discussed. Furthermore, this article provides information about the supposed transmission mechanisms of the disease, as well as the fight against it through chemotherapeutic and environmental sanitation techniques.
A technological approach towards integrated solid waste management in developing countries
2017
This research is grounded in the planning concept of Integrated Solid Waste Management (ISWM). ISWM was developed to promote sustainability in the waste management for developing countries. Waste managers and policy makers in developing countries have been adopting the principles of ISWM into their waste strategies for several decades. But despite their many efforts, still important problems remain, as is the case of low collection coverage, lack of proper treatment of the different waste types, high dependency on final disposal sites and even in some cities uncontrolled dumping is still accepted as the only way to handle the waste. For that reason, waste management in developing countries …
Geschlecht und Gender in der Medizin
2005
Gender specific medicine is a part of gender-research, which has been insufficiently considered up to the present in medicine, sanitation and politics. Part of the scientific medicine simply ignores the knowledge that menand women are different in feeling, thinking and social acting without any question. Doctors often incline to treat all their patients as if there was just one gender: i. e. the male one. It is without dispute that men and women vastly suffer from the same diseases, but they often go through them quite differently. The female body seems to work differently from the male one in nearly all respects - starting with the brain, going on with the heart, cardiovascular, lungs, sto…
Physiological and Structural Responses to Prolonged Water Deficit in Young Trees of Two Olive Cultivars
2022
This study aimed to characterize the physiological and structural responses of potted one-year-old olive trees belonging to two olive cultivars—‘Nocellara del Belice’ and ‘Cerasuola’—exposed to prolonged drought under greenhouse conditions. Two irrigation treatments based on evapotranspiration (ET) were imposed for 69 days, i.e., well-watered (WW, 100% ET) and drought-stressed (DS, 10–30% ET). Leaf stomatal conductance (gs), stem water potential (Ψstem), transpiration (E), photosynthetic capacity (Amax), water use efficiency (WUE), stem (Kstem) and root (Kroot) hydraulic conductance, trunk diameter variations (TDV), and leaf patch attenuated pre…
Current status and development of sanitation and wastewater treatment in the national and international context
2012
El acceso al saneamiento y depuración de aguas residuales es un aspecto de suma importancia tanto desde el punto de vista ambiental como sanitario. Por ello, desde el Imperio Mesopotámico hasta la actualidad se han producido importantes avances en esta materia. Sin embargo, en la actualidad, en la mayoría de los países en vías de desarrollo el acceso al saneamiento continua siendo deficitario. Por otra parte, los países desarrollados, que sí disponen de sistemas adecuados de depuración de aguas residuales, se enfrentan al reto de mejorar la sostenibilidad de estos sistemas. En este trabajo se describe en profundidad el estado actual y evolución en el tiempo del saneamiento y depuración de a…
