What do you think about the current energy transition? Are all the countries ready to forgo the fossil fuels and shift to renewable energy? Will this energy transition help to fulfill the goals of sustainable development from its different sides (economically, socially, environmentally, technologically)?
Relevant answer
Answer
We now know that due to the progressing global warming process, the process of pro-environmental transformation of the economy, including the energy sector, through the development of renewable, zero-emission energy sources is a necessity. Since the average annual increase in the temperature of the atmosphere in the long-term perspective is faster than it was thought until recently, what part of the biosphere can be saved from degradation in the present 21st century depends on the extent to which the pro-environmental transformation of the classic growth, brown, linear economy of excess on a sustainable, green, zero-emission, zero-growth economy and a circular economy in the next several to several years. Unfortunately, the pace and level of effectiveness of the rapid implementation of the pro-environmental transformation of the economy is determined, inter alia, by from the level of economic development of the country, from the equipment with modern technologies, from the potential of financing pro-environmental economic ventures and also from the level of pro-environmental awareness of citizens, including politicians and entrepreneurs. Countries characterized by a lower level of economic development, less equipped with particular categories of capital, achieving lower incomes, have fewer opportunities to finance the pro-environmental transformation of the economy. In addition, due to different conditions resulting from different climatic zones, differences in the equipment with certain categories of raw materials in the earth's crust, different natural and geographical conditions, there are differences in the possibilities of developing individual, different types of renewable and zero-emission energy sources. As far as possible and in connection with the need to diversify energy sources, develop the energy mix, increase energy security in individual countries, various renewable and emission-free energy sources should be developed, including those based on wind, solar, geothermal, nuclear, nuclear and hydrogen fusion, and temporarily possibly also other sources of energy recognized as partially renewable, such as e.g. biomass combustion. Temporarily, natural gas can be used as a replacement for energy based on the combustion of hard coal, lignite and fuel oil as highly emission sources of energy. In addition, in parallel to the pro-environmental transformation of the energy sector, electromobility, sustainable organic farming of only plant crops and other pro-ecological economic projects should be developed in order to achieve zero-emission economy as quickly as possible. Therefore, it is necessary to increase international cooperation in order to develop cooperation and assistance in the efficient and rapid implementation of the pro-environmental transformation of the economy. Developed countries should help less developed countries in this matter. As climate change and the ongoing process of global warming is a global problem, the process of achieving zero emissions in individual countries should also be coordinated and activated at the level of international cooperation. The annual UN climate conferences COP play an important role in this matter. However, the goals set for each stage of achieving zero emissions should be defined, analyzed, verified and corrected on an annual basis, and not in the perspective defined for the next decades.

Due to the current civilization progress in recent decades, acceleration of the development of industry, automotive, urban agglomerations, intensification of agricultural production, etc. and related greenhouse gas emissions, global warming, ozone layer depletion in the atecologicalecologicalmosphere, increase of environmental pollution, growing problem of smog in urban agglomerations, the increase in pollution of the seas and oceans to which unsorted waste is thrown away is cut out as part of the predatory economy of tropical forests in the Amazon and other largest natural forest ecosystems.
In addition, the secondary effect of global warming of the Earth's climate is the increasing, more frequent weather anomalies, including drought, leading to steppe and desertification of areas that were previously natural forest ecosystems or areas exploited by agriculture.
As a result of the above-mentioned processes, every year many species of flora and fauna disappear forever.
As a result, natural biodiversity diminishes, which for millions of years evolved evolutionally on Earth.
In this way the natural resources of the planet Earth are irretrievably in decline.
In view of the above, the issue of environmental protection and biodiversity is one of the most important challenges of humanity in the 21st century.
Classical economics must change towards a green economy based on the strategy of sustainable pro-ecological development.
Therefore, I am asking you for the following query:
How can environmental protection and biodiversity be improved by using current ecological technologies?
Please, answer, comments.
I invite you to the discussion.
Best wishes

These may be "predatory" conferences that send spam to try to increase the number of speakers (who have to pay to participate, but only find out later). If you are reading French, this article may be of interest to you: https://theconversation.com/enquete-les-conferences-predatrices-parodies-lucratives-de-rencontres-scientifiques-86957
Unfortunately, there is not much to do. And answering them by asking them to remove you from their list has no impact whatsoever (according to my own experience). It is best to ignore such messages.

Could anyone tell me where I can find the Canada soil data base which based by HWSD. My research basin located in Quebec, so Quebec soil base is also available.
The format of soil data base should be shapfiles.
Thanks a lot in advance.
Relevant answer
Answer
You can find a coarse resolution soil data-set for the entire country at http://sis.agr.gc.ca/cansis/nsdb/slc/v3.2/index.html
For a more finer resolution data-set, you may go to http://sis.agr.gc.ca/cansis/publications/surveys/pq/index.html#DSS. However, they have the shape files for only few areas in Quebec. I am not sure if your study area lays in there. If it does, it is your lucky day! Otherwise you may need to use both sources.

I am going to start work on biofertilizer, please suggest me which is best biofertilizer for detailed study. Please suggest me a good bio-fertilizer for detailed study? 
Relevant answer
Answer
Dear Neha,
Three types of Bio-Fertilizers,
1.       Rhizobium,
2.       Phosphate Solubilising Bacteria (PSB) and
3.        Azetobactor.
 In the carrier-based (solid) bio-fertilizers, the microorganisms have a shelf life of only six months. They are not tolerant to UV rays and temperatures more than 30 degrees. The population density of these microbes is only 108 (10 crores) c.f.u/ml at the time of production. This count reduces day by day. In the fourth month it reduces to 106 (10 lakhs) c.f.u/ml and at the end of 6 months the count is almost nil.
 Other advantages of Liquid Bio-fertilizers: 
1. contains special cell protectants or substances that encourage formation of resting spores or cysts. 
2. Contains special nutrients that ensure longer shelf life, Better survival on seeds and soil and tolerance to adverse conditions. 
3. Liquid formation ensures that the product is easy to handle and apply. 
4. Since the organisms are stabilized during production, distribution and storage, the activity is enhanced after the contact and interaction with the target crops. 
5. No loss of properties due to storage up to 55 degrees. 
6. Greater potentials to fight with native population. 
7. Dosages are 10 times lesser than the carrier-based bio-fertilizers. 
8. Very high enzymatic activity since contamination is nil.

I'm planning to work on solid waste and its impact on environment. Is understanding of Microflora in dumpsites/landfills help me in understanding any aspect of bioremediation? If yes biochemical test more reliable method or NGS for characterisation?
Relevant answer
Answer
Dear Chandra, in Europe for solid waste there is a specific regulation and in particular if there is a  possible risk for the environmental (H14). In Italy a battery of ecotoxicological tests is provided (Daphnia, algae and fish) only for the water toxicity.
But I think that a characterisation of microflora is necessary in your  study in order to better understand the process involved in the bioremediation, infact microorganisms already present in soil may allow the biodegradation.

BIOWASTE : 23750 TONS/ANNUM
DRY MATTER : 30 PERCENT i.e 7125 T/A
ORGANIC DRY MATTER(VOLATILE) : 70 PERCENT i.e 4987.5 T/A
Digestate(40% DM)
ODM/DAY = 4987.5/365 = 13.66 T/A
Is this the feedstock for my process ? In dranco feed is added in the ratio 1 part fresh feedstock : 6 parts of digestate. Then, What will be total feedstock for my system ? Also, Considering HRT =20 days then what will be the volume of my digester/reactor and Organic Loading rate ? PLEASE CLEAR THIS DOUBT
Relevant answer
Answer
just follow the textbooks, Pratim
as stated by Sunil, OLR descripts the amount or organics (as COD or, in your case as VS, [T] or [KG]) loaded to a system volume [m3] per time ([A] or [D]). In a AD system with recycling, the recicling should be included into the system boundaries. So your OLR only depends on the raw input material and the volume of your digester.
With a raw flow of 23750 T/A = 65 T/D and a HRT of 20 D you'll end up with a volume of 1301 M3. The resulting OLR will be 13.66 T VS / 1301 M3*D = 0.0105 T*M*/d = 10.5 KG/M3*D, which is in the usual range for high solids digesrets as Dranco.

Among my options I'm considering using polylactate, fumarate, acetate, glucose, yeast extract or molasses. ¿at what concentration could work well?
Relevant answer
Answer
As you can see from the above replies, bioremediation is not a silver bullet for chlorinated solvents.
The real thing used in industry (at least in china!) is reduction with zero valent iron: simple iron shavings (wastes from machining metal objects) will tranform into iron chloride and decompose de halocarbons.
This can be done in situ using a reactive permeable barrier, in particular, a ditch filled with iron and other reducing substances (wood branches, organic matter, etc.) When the contaminated water flows through, the decontamination progresses, but this all depends on slope,, water table, etc. and probably needs engineering....
good luck!

Any suggestions of role of sulfates (Na2SO4.10H20) as trace elements in anaerobic synthetic wastewater treatment (glycerol, NaNO3, KH2PO4) in batch reactor (increasing of sulfates in wastewater favorise removal of COD)?
Relevant answer
Answer
sulfur is needed as growth nutrient (approx 1% of dry weight biomass), so in high rate bioreactors it is not a trace element, it must be present at concentrations >> 1 mg/l while trace elements like copper, zinc etc are mostly less than 1 mg/l.except perhaps for iron. Sulfate is a good sulfur source for many anaerobes, sulfate will be reduced to sulfide under anaeobic conditions and that also may act as sulfur source.
For many wastewater sulfur limitation is not a concerns because ist is present already. Even in drinking water usually there is sufficient sulfate.
Sulfate which is added above the nutrient requirements ends up as sulfide. This consumes COD so this does not end up in methane (biogas).So it decreases biogas yield, and sulfide will distribute among liquid and gas and thereby deteriorates biogas quality. On the other hand, this may be used benficially to remove sulafte from wastewaters
