Recent Developments

Fresh water resources are depleting rapidly as the water demand around the world continues to increase. Fresh water resources are also not equally distributed geographically worldwide. The best way to tackle this situation is to use solar energy for desalination to not only cater for the water needs of humanity, but also to offset some detrimental environmental effects of desalination. A comprehensive review of the latest literature on various desalination technologies utilizing solar energy is presented here. This paper also highlights the environmental impacts of desalination technologies along with an economic analysis and cost comparison of conventional desalination methods with different solar energy based technologies. This review is part of an investigation into integration of solar thermal desalination into existing grid infrastructure in the Australian context.

Wastewater Samples

Water recycling is a sustainable way of managing water resources because of the large consumption of fresh water in the world caused by population growth, urbanization, and industrial development. However, the reuse of freshwater requires serious care due to the appearance of contaminants after its use, such as active chemicals, micropollutants, and pharmaceutical products. This study presents a systematic review of articles that includes terms of techniques used to assess metals and organic compounds in wastewater samples (a combination of effluents and water originated from bathrooms, showers, and kitchen sinks, and rainwater between the years 2000 and 2020).

Spain throughout history has hosted many civilizations. With its climate,geography, fresh water resources and vegetation, it is one of the most favorableplaces to live in the world. Therefore, many communities lived here. Especially, theestablishment of the Umayyad Caliphate was a very big chance for Spain. In theperiods when the Islamic world was the most advanced civilization, the biggestphilosophers and scientists of Europe raised in this geography. Scholars such as IbnRüşt and Ibn Meymun taught European students. While, the Kings in Europe areproud of the several thousand volumes of books in their libraries bragged, 400thousand volumes of books existed in the library of the Andalusian Caliphate. Thedestroyed Muslim and Jews with the Reconquista took also the richness and thecivilization of Spain. By contrast, Spain has found something new: Geographicaldiscoveries and gold. After these events, Spain became one of the world's largestcolonial empire, but in XIX and XX. Century, Spain lost power and withdraws to theIberian peninsula Over time, Spain has become one of Europe's most powerlesscountries sicne their economy was based on primitive agriculture. In this process,the Kingdom, dictatorships, military coups and republics were established. In theseprocesses Spain has seen continuous coups and coup attempts. In 1936, the armyhad rebelled once more against the legitimate Government. However this time therebels were supported by the foreign powers. Imperialist States were the financiersof the bloody civil war occurred between 1936-1939.

Energy Dependent

The world population is expected to increase up to 8 billion by 2015. Most of the cities in the world are scattered around the fresh water resources. These cities and villages have their own interests and they constitute a power order. Therefore, we have been trying to harmonize these cities and villages in the usage of fresh water resources and the discharging of wastewater as well, by using an engineering means of water treatment. However, fresh water resources, which are essential to our lives, have a constant amount of circulation with a period of one week to ten days. The science and technology of the water environment should recognize the limit of fresh water resources for the sustainable development of society, because the water service industries are the essential infrastructure of the community. In order to implement an appropriate risk management it is necessary to identify the goal of environmental management considering the social, natural and economical conditions. The energy-dependent technologies should be reconsidered to consume less energy and undertake more resource conservation engineering. Water science and technology cannot supply all the answers, therefore more comprehensive water management systems should be developed by other sectors, such as the food production industry.

The rapid growth in world population and limitation of soil and water resources have caused major problem for human nutrition security in the world. only 3% of water resources are fresh water.  Accoding to the FAO report, if in the  any  country  Amount  of  fresh  water  is  less  than 1700m3   per capita, this country is faced to serous water shortage. At the present, in the 22 countries share of fresh water per capita is less than 100m3and in the 18 countries is more than 2000m3. Therefore, Azerbaijan is one of the countries which have faced serous water shortage.

Global Water

The article provides an analytical overview of the state of global water resources and their use in the world. The focus is on the most important component of water resources – freshwater, which on the planet is only 2.5 % of the total. The most accessible renewable water resources are river runoff, which is distributed unevenly on the surface of the planet: Asia (32 %), South America (28 %), North America (18 %), Africa (9 %), Europe (7%), Australia and Oceania (6 %). Along with the characteristics of the known components of freshwater resources (river runoff, groundwater, glaciers), attention is also focused on trends in attracting unconventional sources (recovered wastewater or gray water, desalinated, specially collected rainwater). The total use of fresh water in the world is only 9 % of the total river flow of the planet. At the same time, the problem of water scarcity was included in the list of the World Economic Forum 2015, as one of the global risks in terms of the potential impact on human society in the next decade. Among the causes of global water, scarcity are geographical and socio-economic. Geographical reasons are the spatial and temporal (seasonal) mismatch of the demand for fresh water and its availability. Socio-economic reasons are the growth of the world’s population, urbanization, improving living standards, changes in consumption patterns, and an increase in irrigated land. The latter has become key to the growth of global water demand. Experts forecast that the limited access to fresh water in 2050 can be felt by 3.3 billion more people than in 2000. The article gives examples of a methodology for the hydrological assessment of water scarcity (calculation of the ratio of the volume of annual renewable water resources to the population) and the methodology of economic and geographical assessment. Other approaches to assessing water resources by creating new paradigms (water – blue, green, virtual, water footprint) have been characterized. Throughout the history of mankind, there have been many conflicts related to water. Active water cooperation between countries today reduces the risk of military conflicts. This conclusion was made after studying transboundary water relations in more than 200joint river basins, covering 148 countries. The right to safe water and sanitation is a fundamental right of everyone (UN, 2010). Therefore, among the 17 sustainable development goals adopted by the UN for implementation for the period 2015-2030, Global Goal 6 “Clean Water and Good Sanitary Conditions” is aimed at ensuring sustainable management of water resources and sanitation for all. This will save people from diseases, and society will be given the opportunity to be more productive in economic terms.

The article examines the problem of fresh water, since in terms of water supply from its own resources per capita and per 1 km2, the republic is 8 times behind Georgia, 2 times behind Armenia. Significant water consumption in Azerbaijan is caused by its arid territory with a predominance of active temperature and a lack of precipitation, which leads to intensive irrigation of crops. At the same time, artificial irrigation is used on 70% of the cultivated land.

Collaboration Platforms

In many parts of the world, management of water resources and infrastructures is fragmented between agencies at multiple levels – state, provincial, and local – and sometimes between functions within individual agencies. Consequently it is often impossible to take a holistic view of the issues at hand to enable effective management of the resource or infrastructure – either because of the overhead of managing the coordination required, and/or because of politics between the different stakeholders. In their work for IBM, the authors created a concept of an information technology (IT)-enabled “collaboration platform” that integrates different water data sources with IT tools to enable multiple entities to maintain and share a “common operating picture.” This greatly assists with coordination and reduces politics to manageable levels. In this paper, the authors describe the collaboration platform and its benefits by reference to examples of such platforms in use, and propose a reference technical architecture for creating collaboration platforms.
