What are the new technologies for desalination and purification of seawater without the consumption of electricity that can already be applied in areas with freshwater scarcity?
But the scarcity of drinking water occurring in an increasing number of countries in Europe and also on other continents is caused not only by the progressive process of global warming, but also by unsustainable agriculture carried out in ignorance of the planet's climate and biosphere. But the scarcity of drinking water occurring in an increasing number of countries in Europe and also on other continents is caused not only by the progressive process of global warming, but also by unsustainable agriculture carried out in ignorance of the planet's climate and biosphere. The over-intensive, production-intensive cultivation of agricultural crops, mainly for the production of fodder for livestock rather than food for humans, and the production of exotic fruit sold mainly in supermarkets and hypermarkets in other countries, is also a significant factor in the excessive consumption of surface water and rainwater and the decline in drinking water levels over ever larger areas.
In view of the above, I address the following question to the esteemed community of scientists and researchers:
What are the new technologies for desalination and purification of seawater without the consumption of electricity that can already be applied in areas characterised by freshwater scarcity?
What do you think about this topic?
What is your opinion on this subject?
I invite you all to discuss,
Thank you very much,
There is considerable unclearness about efficiency terms in water related literature pertaining to agriculture - irrigation efficiency (E), (crop) water use efficiency (WUE), and agricultural water productivity (WP).
The "usefulness of these terms for planning and decision making depends on consideration of the scale and local conditions under which these values are obtained. For example from the WUE aspect, releasing cold resistant crop varieties could improve crop yield and hence crop WUE, because of a production increase (increase of the numerator), without any linkage with the denominator." (from Heydari, 2014)
Can someone explain this example? Are there other examples for other efficiency terms? More detailed explanations are welcome! Thanks in advance!
I am looking forward to receiving scientific documents demonstrating successful villages which overcome water crisis issues through public participatory approaches.
What’s a best method of water management in case of an agricultural drought? Which bill provides details for regulation and control of groundwater?
I am actually in Mozambique working on a rural development project. My department is actually involved as partner to do assessment and design activities, but we would love to insert some hot research topic in the thing.
I am interested in:
- Understand possible research topics and open hydrological/water management/water harvesting problems (mainly in Zambezia province)
- Ask if you know possible data available online
Thanks to whoever will contribute!
For example: Iran falls within the Middle East arid zone, with some 13% of the country receiving less than 100 mm mean annual rainfall, an additional 61% receiving less than 250 mm and only 9% receiving more than 500 mm.

The importance of water resources is evident, and its management through all levels is
imperative, especially in arid and semi-arid countries where water demand is highly required for irrigation and for the drinking.
what are the best methods of water management in the case of an agricultural drought ?
Our need to create alternative water sources is increasing day by day. However, while providing alternative water resources, can we adequately predict long-term effects on the natural balance? Although the dams built on rivers and streams are useful as an irrigation and energy source, serious damage occurs to the habitat on the natural passage areas of the streams. Similarly, can rainwater harvesting in urban or rural areas (especially covering large areas) cause adverse effects both in terms of feeding aquifers and soil-water balance? I don't have a clear opinion on this subject, but I think that we should question how we affect nature in the long run and that we should take our steps carefully.
I mean, is it possible to deliver water as water vapor to the plant root zone? No matter which irrigation method is used, plants cannot benefit from a significant portion of irrigation water. Because we actually give water to the soil, not to the plant. The plant is able to use the water left over from evaporation and deep percolation. Even if we assume that there is no deep percolation, a significant part of the water evaporates from the gaps in the soil. As a suggestion, I think that water can be applied in the form of water vapor to save water in agriculture. Similar to the subsurface drip irrigation system, when the water vapor reaches the root zone of the plant, it can feed the plant roots. There are several methods for evaporating water, but it is necessary to determine an economical and viable method under field conditions.
Comprehensive ground water management requires suitable tools that consider the groundwater balance as well as the variety of potential risks that might impact groundwater recharge and chemistry. Due to cascading anthropogenic effects, particularly in urban areas this forms a challenge. Which simulation and management tools (both, freeware or licensed software) do already exist?
We need international support to collaborate and finance inter-institutional research, development and innovation projects in the field of smart water management in the current context of climate change.
SWRM is essential for judicious allocation, usage of water resources, thus asists in alleviating the adverse effects in water scarce regions.
Socio-Hydrology, as a relatively new paradigm in resilient water management, has gained increased attention these days in reconciling contrasting issues in the fields of natural and social sciences.
Hence, there need effective and appropriate tools, models, and approaches to conduct researches so as to enrich this multidisciplinary field of study and ensure effective utilization of this vital but scarce resource, especially in areas where human communities are living in close proximity to natural water systems.
It is a general fact that human societies across the world are being challenged with significant water-related problems such as ecosystem degradation, groundwater depletion, natural and anthropogenic drought, and floods, water-borne health issues, and deforestation which are being exacerbated by climate change.
I'm using three different performance criteria for evaluating my model:
2.Percent bias (PBIAS)
3.Root mean square error (RMSE)
You can suppose that I used a regression model to estimate a time series data such as river mean daily discharge or something like that.
But for a single model and a single dataset, we saw difference performances for each criteria.
Is this possible? I expected that all of these three criteria have same results.
You can see the variation's diagram of these criteria in appendix pic.
Dear Researchers: Decent citations have been received to a recently (Mar'21) published paper on one of the traditional water harvesting systems practiced in India (for the last 2,500 years!!!). Quite unexpected to witness the emerging interest of modern researchers in ancient technologies. Is it there at your end?
As we know the problem of floods and water logging are increasing day by day especially in India and other Asian countries, and recently we saw many floods in the Indian subcontinent. Similar conditions took place in Wuhan but the Concept of Sponge City was a game changer. In Maharashtra (India) similar conditions arised this monsoon and I wanted to check that can a similar concept like sponge city be implemented in Maharashtra for sustainable flood management. So, if anyone can guide me on how to approach this project it would be a great help, looking forward to get answers.
We are aware that a shift in monsoon peak discharge may have an adverse impact on several water-based applications such as agriculture, dam operations, etc. E.g.
Urea is the major nitrogen fertilizer in India almost 80% of the nitrogen fertilizer is in the form of urea, so application dynamics of urea with relation to irrigation has a prime importance to increase the NUE and WUE.
Dear Researchers, Water Managers, Climate Experts, and Policymakers,
By understanding the ways in which ancient communities were successful at or failed in attaining sustainable water management, recent studies have attempted to provide important information for modern communities facing climate change impacts which are consequently resulting in water scarcity, security, safety, and sustainability issues. For example:
Conference Paper Study of Vandiyur Tank Cascade System in Madurai: Exploring ...
Can the perspective of re-implementing ancient and indigenous techniques of water management in contemporary conditions be considered as an imperative proposition to drafting modern water management policies? Your opinions, observations from your case studies, and evidence from your published work, if shared, will be gratefully appreciated.

I would like to ask your opinion about
- what do you think are the most relevant research directions?
- what are the key questions of urban water regulation in the African context?
- what analysis methods should I review?
- how would you describe the most important goals of a water regulation analysis?
I would be happy to read your opinions and related literature as well. Thank you very much for your answer and suggestions! Kind regards
Which method is most suitable and recommended as the best water management practice in the world, i.e. Drip Irrigation, Sprinkler Irrigation, Flood, Furrow, Ridges, Center Pivot, or any other method like Hydroponic or multi-story building.
Need your expert decision.

For a semi-arid region with water shortage, how much yield reduction (with the implementation of deficit irrigation strategy) is acceptable for farmers?
The explosive multiplication of human has exerted a huge pressure on the natural resources on earth including the water, forest and wildlife. In return, he pushed all these natural resources on verge of extinction. But the human life is completely depending on these natural resource in many ways and without these resources, the human life could not be even imagine. Now the question arise here. What will vanish out first from the earth either Water or Human...???
Please contribute your views and relevant literature. Regards Dr. Shankhwar
The water crisis is a situation that affects us all, however:
Is there a principal responsible for water management?
I am well aware that all infrastructure and water management planning functions are to some extent political in nature. Apologies for a very broad question, I am interested in other researchers opinions and experiences.
I am interested in (a) how damaging can 3/4 year election cycles be on water sector outcomes? (b) have any attempts been made anywhere to protect public water sector from political cycles? (c) sometimes I'm sure political champions are a great benefit to water sector outcomes, what are some good examples of this?
I welcome both links to research, and also personal opinion and experiences.
I have carried out research on Characterization of soil Arsenic contamination & mitigation options through water management and varietal selection of Rice for my masters dissertation & am currently associated with research project for PhD in observing the efficiency of Yellow Gypsum, an industrial waste turned soil conditioner,in increasing Plant available Sulphur and micronutrient content as well as changes in different soil physico-chemical and microbial parameters, in different soil-systems, under different cropping system.
So, I will be grateful to know about any opportunity related to this line of work to fortify parts of my PhD Thesis.
It seems to me that this gap becomes larger and larger despite the fact of very intensive involvement of new concepts, methods, organisations, institutions and technologies. For example the most of new methods, concepts, approaches, initiatives and organisations dealing with flood and drought attenuation and river restoration or revitalization despite their good intention did not considerably improve flood and water management in critical situations. Their costs are very high and the success is questionable.
“How can hydrology be more efficient and effective?”
As I know, there are two ways of controling the moisture level in MEA of UR - PEMFC:
- Active water management - with the use of pumps for water transportation
- Passive water management - achieved by the structure of materials, such as hydrophilic and/or hydrophobic configuration.
Please give your examples and detailed explanation.
Thank you very much!
Why, historically, several peoples have been able to manage and control water with wisdom and rationality, like Faggara and other traditional methods, while we find the problem of water now despite scientific development.
Can someone help me understand why cellulose acetate butyrate is more hydrophobic than cellulose acetate?
I prepared nanofibers by electospinning of both polymers and both have initially the same contact angle, but after some time (10 mins) the water manages to enter the cellulose acetate nanofiber mat and contact angle changes from 130 to 90 but for CAB no such contact angle decrease is observed?
I know hydrophobicity of CA is dependant on the degree of acetylation and because obtaining DS of 3 is practically impossible, there will always be some hydroxyl groups which can be the reason water gets into it over time. I am not completely sure about CAB, its chemical nature, why is it so hydrophobic, strangely there is not much scientific lit on CAB? Is there a reason for this?
And what are the steps for sustainable water management?
Due to environmental impacts of dams such as:
- problems for the surrounding area, for plant life,
- dams block up flowing bodies of water, such as rivers, any animals that depend on the flow to reproduce or as part of their life cycle are put in danger.
- Harm water quality and temperature.
- Block fish migration
Which are related to technical knowledge as well as to knowledge about the environment

Grey water is one of non-conventional water resources in many countries as Saudi Arabia, Norway , Jordan and other countries. This due to grey water can be treated easily in comparison to Black water.
I have searched the following sources and attributions:
1) Based off a 2007 Green Peace report, the total dissolved solids for Marilao river is 1765-3285 mg/L. However it did not mention the mineral composition of the said river, namely (from Chao Pan's and colleagues' article):
b) Nitrate (as N)*
c) Alkalinity as mg/L calcium carbonate
d) Water hardness as mg/L calcium carbonate
f) silicate (as silicon dioxide)
2) From the Philippine Journal of Science, there were no mentions on the composition of the Marilao river.
3) Water Quality assessments based on water management authorities have no report on the Marilao River or the Meycauayan River. However, they do have those from Laguna rivers or Rizal rivers (e.g.: Morong-Teresa river system). However, I doubt that the proportion of the minerals will be the same given that the geological composition of the two river systems (Morong-Teresa vs. Marilao-Meycauayan-Obando river systems) differ.
*What would be a good substitute if not the Marilao river?
Some single or multi-jet water meters (like this one: https://www.heatingandprocess.com/wp-content/uploads/2016/03/Elster-M170-Water-Meter-Product-Data-Sheet.pdf) having an inbuild Magnet Protection against tampering with magnets. My questión is: How effective is this protection or is it necessary to take additional measures to avoid (magnet-) tampering? Especially: How it depends on strength and distance of the magnet from the meter?
I am working on a project regarding water intensive sectors. An objective of this project is to analyze which countries are the frontrunners when it comes to having a circular/sustainable agriculture sector.

Thanks in advance!
I am an undergraduate student and I have to conduct a research in Ecuador soon. My goal is to investigate whether community-based water management (vs. other types of water management) can help reduce inequalities/discrimination of ethnic minorities.
I believe that the best way to see if inequalities have dropped since the installation of this new system is to research the level of inequalities (economical, gender-related...) in a specific town:
-before the system was installed (through interviews and other data)
-after the system has been installed (through interviews)
This would show me how inequalities changed but I guess I would need to compare it to a "best case scenario" where there are no inequalities. I do not know whether I should compare my results to:
-the average values in Ecuador
-a town with similar characteristics but with a different water management system
I do not know whether my research methodology makes sense, I feel a little stuck and would appreciate any help. Thank you!
