The Black sea protection initiative: What should we remember?



Authors:Dr. Dmytro Cheberkus and Sophia Zherebchuk

In XXI century everyone in our planet become to understand how fragile the ecosystem is. The key words in every ecosystem description tie with equilibrium and stable balance. This equilibrium or stable balance could be destroyed due to the invasion of new species, the death of existing species, natural disasters or man-made causes. Advocates of an environmental ethic consider that the best way for protect ecosystem is to leave it alone, not interfere, and let nature follow its own course. Certainly, there are many cases of appropriate human interference. But the qualified assessment should be the obligatory component in every case, especially within the EU instruments or projects.

The Black sea basin is most contradicting regarding political and security issues and the most polluted sea basin in EU. Today, the Black sea has serious problems with eutrophication, pollution and colossal impact of the biota invaders of rapana, mnemiopsis and other species. Besides the Black sea suffers from exosystemic harm caused by human interference. In this regards, the Ukrainian authorities should take all necessary protection measures. 

But without deep scientific assessment any activity could become a disaster for the Black sea, like many years ago the human impact caused the death of Aral Sea.

If we are talking about case study, we need to put the stress on several projects that implement without any social and ecological assessment and in the same time could cause ecological disaster.

In the end of 2020, near Mykolaiv on the Kinburn spit on top of the allegedly existing natural mussel field “artificial reef” was created. Shells of imported oysters from the garbage heap of a restaurant selling live imported oysters in plastic bags have become one of the materials for this reef. But such a “unique” solution is extremely dangerous for the Black Sea ecosystem. Organisms, larvae and their eggs, as well as infectious diseases that live in the overgrowth of shells and oyster meat are alien to the local fauna and may become new harmful invaders – aliens for the Black Sea.

Besides 2.5 tons of oyster shells the project participants also dropped into sea the plastic bags and other garbage like rusty metal, which during decomposition will also pollute the Black Sea with extremely dangerous microplastics.

Thousands of Black sea mussels caused by this experiment are just died under the garbage bags that were placed over them. Thus, part of mussels that could cleanse the sea by filtering the water were blocked and became victims of rapana. 100 bags of garbage lay on the “carpet” of mussels and a pyramid on top of each other around the rusty pipes, blocking the possibility of filtering water on the mussels and leading to their partial death.

Also the plastic bags with a fine mesh were used for reef’s construction. No need to remind what is the ecologists opinion about the fact that abandoned (forgotten, lost) in water plastic fishing nets for years (until they collapse) continue to catch and destroy fish, crabs and other inhabitants of the sea, who become entangled in them and perish. Thousands aquatic organisms like crabs, shrimps, fish may be, and will be in this trap and die when will not be able to leave. This is not about biodiversity increasing of the Kinburn Spit.

At the same time, many unsuccessful construction attempts of reefs from unnatural materials are known: car tires, plastic waste etc. These reefs were destroyed and polluted the coast and sea-ocean. The material for sprouting (the plastic bag) is on the surface, the oyster’s shells are inside and they not sprout.

Also, we should remember that there is currently no oyster nursery in Ukraine; landing material (spat or grown juvenile oysters) is imported either from Europe (France, Spain, Ireland, England, etc.), or from the Far East (Sakhalin). Import to Black Sea associated with the risks of bringing dangerous infections into this region. It is known that state and industrial control over dangerous diseases of oysters is ineffective.

Oysters, like many other bivalve molluscs, are susceptible to various diseases. The causative agents of oyster diseases can be viruses, bacteria, fungi and protozoa, and also various types of worms and crustaceans. The degree of knowledge of diseases of different the types of oysters are significantly different. Usually oyster diseases are most commonfound in places of their mass concentration (oyster banks) and areas cultivation of molluscs. Mycoses are a serious danger to oysters, caused by parasitic fungi. The most dangerous and widespread disease of oysters of fungal etiology is shell disease, caused by the fungus (Ostracoblaba implexa).

Shell disease in the Black Sea for the first time registered in 1975, was found on all the largest oysters in the northwestern part of the Black Sea. Given the high degree of oyster infestation (up to 99 %) it, apparently, was one of the reasons for the mass degradation of natural populations of this species in the northwestern part of the Black Sea. Currently European oyster in the Black Sea is on the verge of extinction, listed in the Red book of Ukraine.

Other possible reasons for the decline in the number of European oysters in Black the sea is considered to be cumulative toxicosis caused by pollution of marine areas, deterioration of hydrochemical (oxygen) and hydrobiological (feed) conditions habitats due to the eutrophication of offshore areas, as well as a wide distribution in the Black Sea of ​​a predatory introduced species – the gastropod mollusk rapana (Rapana venosa).

Despite the extensive list of infectious diseases known in oysters we have a few experts in Ukraine regarding oysters’ diseases. Experience in oyster farming in the Black Sea has shown that some local diseases of molluscs, such as shell disease, clionosis, hexamitosis and others can also infect oysters imported into this region.

Accommodation in the water area of ​​the nature reserve fund of various types of adult oysters grown in areas remote from the Black Sea should be strictly prohibited due to the high risks of infectious diseases and harmful invaders.

Another example of harmful actions is the decision of Mykolaiv regional authority about lend sales in the Sviatoslav National Nature Park that included in the Emerald Network of Europe. In the case of the implementation of these plans the orchid field will be finally lost, millions of rare plants and animals listed in the Red Book of Ukraine will be under threat.

In this regard, the approach to the projects’ implementation should be changed on national and international level. United Nations Convention on the Law of the Sea of 10 December 1982 already has the provisions regarding the protection and preservation of the marine environment as far as marine scientific research. Ukrainian authorities should apply these provision and guarantee that every interference into Back sea ecosystem should accompany with deep scientific assessment.

The in EMBLAS project in Ukraine. With the aim of strengthen the capacities of Georgia, Russia and Ukraine for biological and chemical monitoring of water quality in the Black Sea in line with EU water-related legislation EU and UNDP established the improving Environmental Monitoring in the Black Sea (EMBLAS) project.

The international initiatives (within EMBLAS, UNDP, World Bank, CMA etc.) are really important and could be the powerful tool for ecological monitoring and capacity building I the Black sea.

A Treaty to Preserve Oceans – And Our World

Avatar photo



There is cause for celebration in our climatically distressed world for a treaty of historic proportions has been signed by the UN member states.  It is the culmination of 15 years of talks and discussions.

Vital to the preservation of 30 percent of our earth, i.e. land and ocean, the oceans treaty broke many political barriers.  The EU environment commissioner Virginijus Sinkevicius applauded the event saying it was a crucial step towards preserving marine life and its essential biodiversity for generations to come. 

The UN Secretary General commended the delegates, his spokesperson calling the agreement a “victory for multilateralism and for global efforts to counter the destructive trends facing oceanhealth, now and for generations to come.”

The real problem is the oceans belong to no one — and thus available to everyone — because the exclusive economic zones of countries end beyond 200 nautical miles (370 kms) from their coastlines.

These high seas are threatened by overfishing, man-made pollution including damaging plastics, and also climate change.  People are unaware that oceans create half the oxygen we breathe, and help in containing global warming by absorbing the carbon dioxide released by human activities — one can think of all the coal and wood fires, particularly in developing countries, and the coal-fired power stations everywhere among other uses of fossil fuels.     

The fact is we have to value the environment that nurtures us for the consequences of our disregard can in the final analysis destroy life itself.  As it stands, the World Wildlife Fund (WWF) reports in its 2022 Living Planet Index a 69 percent decrease in monitored populations since 1970, a mere half century.  Their data analyzed 32,000 species.

As the apex species, such a loss forces humans to assume responsibility.  It rests on each and everyone of us from individuals to governments to corporate entities, and across the spectrum of human activity.

The treaty furnishes legal tools to assist in creating protected areas for marine life; it also requires environmental assessments for intended commercial activity … like deep sea mining for example.  The nearly 200 countries involved also signed a pledge to share ocean resources.  All in all, it has been a triumph of common sense over the individual greed of people and nations.

So it is that the treaty has made possible the 30×30 target, namely, to  protect 30 percent of oceans by 2030.  Now comes the hard work of organizing the protection.  Who will police the areas?  Who will pay for it?

Environmental Crisis in South Asian Countries

Avatar photo



During thetwenty-first century, South Asian countries have been facing and dealing with enormous problems. But the environmental crisis is one of the major and most emerging issues. South Asia is the southern part of the continent Asia, which is also known as the Asian societies. Mainly consist of eight countries India, Pakistan, Afghanistan, Bhutan, Maldives, Nepal, Sir Lanka, and Bangladesh. Most of the environmental problem has been started after the 1960s due to high economic activities, population growth, industrialization, urbanization, and poverty. The combined effects of all these factors caused the situation more complex because of less management of negative and deviant behavior in economic activities. South Asian countries are the developing region that mainly constitutes middle-income countries struggling to flourish their economies and to cope with challenges of political and environmental sustainability, although they are still yet facing many environmental crises which are highly interactive, interlinked with human activities and also human life which it is the need of the hour to be addressed.

Population Density and Population Pressure

Population growth is one of the major elements which play an important role in environmental crises. As all the South Asian developing countries have an extensive density of populations such as India which considers the world second most populated country after China, because the growing population in all South Asian countries, it’s put tremendous population strain on natural and environmental resources such as increase the extraction of resources from the environment influence negatively in our environment.  The   Intergovernmental Panel Discussion (IPCC) on climate change says that most of the environmental crises are attributed to human activities. The population of Pakistan is also increasing at the rate of 1.9 % annual changes and the population of other South Asian countries is also not up to the mark, but increasing day by day which adversely affects the economy and the natural setting of the environment.

Climate Change

Climate change is also a major problem. South Asian developing counties are vulnerable to climate change-related disasters. The history of Pakistan, and Bangladesh showed how much they suffered due to climate flood disasters. Pakistan and India are facing the brunt of extreme weather almost every year. Being affected by environmental problems severely influence economic activities in the summer of 2022 due to “Heat Waves” in India and Pakistan, “Flood Crisis” in Pakistan last year affected the largest region about one–third of the whole country. Melting glaciers in Pakistan, almost twenty glacier bodies in Nepal, and twenty-five in Bhutan are so unsafe glacial water bodies. Land erosion in India, and Nepal land erosion, and land sliding. With rising sea levels in Bangladesh, Maldives, and Pakistan it is expected that by 2050 most of them swallowed by the sea. This climate condition is not new for this region, according to the World Bank Report 750 million people across South Asian societies are impacted by the last almost 20 years. In Afghanistan, farmers face climate-induced drought, and nearly 19 million Afghans are unable to feed themselves and almost 5 million people across India and Bangladesh. According to the climate change risk index Bangladesh and Pakistan ranked sixth and seventh while India ranked fourth among them respectively. A recent report of intergovernmental on climate change called “Code Red for Humanity” by UN Secretary-General Antonio Guterres, it is predicted that in the next two decades, global warming will increase up to 1.5 degrees Celsius.


Almost all Asian societies adversely face the problem of pollution associated with indoor and outdoor elements which may be the source of pollution. With the increase of demographic pressure and urbanization, pollution is also considered a vital concern in South Asian countries. Due to industrialization, transportation, burning of coal, and biomass, excessive use of metals, and soil depletion of natural resources and minerals merely falls under the category of pollution. According to the report of the Air Quality Life Index Pakistan is the fourth most pollution-causing country in the world and India is the second most polluted country in the world and number one in Bangladesh. Excess methane, carbon dioxide, nitrogen, sulfur, and insoluble and soluble materials emitted by vehicles and industries are harmful effects on humans such as lung cancer, asthma, and water-borne diseases. It badly influences plants and animals.

Water scarcity

Water scarcity is a major concern in almost every region. South Asian countries have become water-default regions due to population exploitation, and unplanned urbanization. Almost 90- 95 of water is consumed by agriculture and industries, and there is insufficient storage and a wasteful irrigation method. Per capita, water availability is less than the world average and 4.5% of freshwater resources availability. Pakistan, India, and Afghanistan face varying degrees of water scarcity. Groundwater depletion caused by irrigation, agriculture runoff, industries, and the unregulated release of sewage needs a major concern. Along with scarcity of water quality and quantity, both are also affected by the reduction in the quantity of water because of the recession of glaciers and disruption in the monsoon.

Global warming

Furthermore, global warming is also a main issue that is observed globally it is specifically due to human activities primarily the burning of fossil fuels such as coal, and petroleum, fire burning, and along with the emission of harmful gases. South Asian countries are the major source of carbon dioxide, so it is a crucial component in global warming. However many South Asian countries implement a tax on the use of carbon-related components, a form of small fiscal policy to reduce the concentration of carbon in the atmosphere.

Energy Crisis

In addition to all these South Asia approximately uses only 5.9 % of global energy resources excluding the non- commercial energy resources. South Asian counties have increased the demand for energy in the last few decades, increasing demand by up to 50% since 2000. The rising energy demand is induced by population growth and the manufacturing sector. All the south Asian countries have increased the demand for electricity on average by more than five percent annually over the past two decades and are expected for the future that requires more than double by 2050. More than two third of the energy is imported. So it put pressure to increase cost recovery if the demand increase. In South Asia, disruptions due to conflict among other countries adversely impact fuel imports and put greater pressure on the government to ensure the security of their energy supply.


South Asian countries are major part and contributors to the world economy. Due to the crisis, economic activities were destroyed and diminished in many regions, because of damage to productivity and infrastructure, security threats, and mass migration, as the results growth rate declined and the world economy gets affected. Globally, all the economies of the world somehow depend upon each other for trade. To facilitate this connection it is necessary to maintain a balance. There are many organizations are working in South Asian countries to control the environmental crisis, such as the intergovernmental organization of South Asia Co-operative Environment Program (SACEP). Climate Action Network of South Asia, South Asian form for the environment. So the main purpose of all these organizations is to provide support, protection, and management in context to contribute in terms of sustainable development, along with issues of economic and social development. In addition to all these, urgent action is needed to curb all the challenges. The most immediate and pragmatic step to cope with the challenges is to make a collective UN committee for collaboration among the countries, reduce the global emission of harmful gases, decarbonize the energy sector, educate people to spread awareness among people start campaigns related to the protection of environmental at county level, uses of renewable resources, new policy initiation, formulation, and Implementation.

The Old Earth and Earthquakes in 2023: Accounting the Damage

Avatar photo

Gaiya’s hypothesis points to the earth as a living. The elements that support human life on earth, starting with the lithosphere and ending with hydrogen, argue that the earth is also like a living being, it’s just that this hypothesis cannot be scientifically proven. But to say that the earth is old is not only to brag. Just as the human body is aging and experiencing a functional decline, it is most often affected by the disease. The same goes for the earth on which humans live.

It is undeniable that since the beginning of 2023, earthquakes have affected many regions of the earth. In Indonesia, throughout 2023, there have been at least 11 large-scale earthquakes, the last of which occurred in Jayapura with a magnitude of 5.4 on the Richter scale. Meanwhile, at the global level, Turkey and Syria are still struggling to recover from the earthquake that killed as many as 36,000 people on February 14, with estimates of physical damage not yet calculated. Natural disasters like earthquakes, which have become more and more massive in recent times, have, of course, increased self-consciousness in society. Aside from this fear, earthquakes also cause a lot of damage and loss, both on goods and lives. Natural earthquakes are never caused by man. Yet humans can still learn this. In 2023, seismic registers will be completed with the results of the earth’s natural activity.

The reason that the land is old may always be a valid argument today. This old earth makes the tectonic forces that exist below the Earth’s surface stronger. These tectonic forces can set off earthquakes when the plates of the earth cooled.

The causes and effects of the earthquake

Small-scale earthquakes are not always innocuous, but large-scale earthquakes are certainly more dangerous. The structure of the soil and the area of a site influence how earthquakes may damage the site.

Earthquakes are vibrations or shocks which come from inside the earth. The natural cause is the movement of the terrestrial crust. The Earth consists of many different layers, which consist of the heart of the Earth (liquid or solid), the mantle, the Earth’s crust, and the lithosphere. Each layer has different properties and features. The lithosphere is the outermost layer and is made up of tectonic plates that come and go. When tectonic plaques move, they cause earthquakes. Earthquakes can also happen due to volcanic activity, where magma from inside the earth enters the surface.

An earthquake is a natural phenomenon that may cause serious environmental damage. Earthquakes have the potential to cause a variety of impacts, not only damage to physical structures, but also damage to the environment. Earthquakes can cause a variety of negative environmental effects, including pollution and damage to ecosystems.

First, earthquakes have the potential to contaminate the environment. Earthquakes will cause the breakdown of physical structures such as buildings, roads, and bridges, which will cause hazardous materials such as asbestos, chemicals, and waste to spread into the environment and cause environmental pollution. In addition, earthquakes can also lead to dangerous gas leaks, such as poisonous and irritating gases. It can irritate the respiratory tract, nervous system and skin and cause poisoning.

Second, earthquakes can wreak havoc on the ecosystem. Earthquakes can cause turbulence in sea water, which can lead to loss of habitat and even death of marine animals. This can result in the loss of valuable habitats that contain many organisms. What’s more, earthquakes can also cause damage to forests, especially on mountain slopes. Earthquakes have the potential to destroy trees in forests, resulting in the loss of habitat for many wildlife.

Third, earthquakes may cause environmental damage as a result of tsunamis. Tsunamis are large oceanic waves due to earthquakes. Tsunamis can wreak havoc on the environment. Tsunamis can destroy buildings, bridges and roads, resulting in environmental damage. In addition, tsunamis may also cause damage to the ecosystem, such as loss of habitat for birds, fish and other animals.

Fourth, earthquakes can harm the environment because of landslides. A landslide is a natural process in which the ground, rock and other materials are washed away by water or wind. Earthquakes have the potential to cause avalanches and environmental damage. Landslides may flood areas adjacent to the landslide site, resulting in the death of plants and animals in the area. Landslides can also result in the release of hazardous waste into the environment, which can cause further damage to the environment.

Fifth, earthquakes can wreak havoc on the environment. Lahars is a blend of water, rock, earth and other materials from volcanic eruptions. Lahars can cause great environmental damage. Lahars can cause flooding of surrounding areas, which can make the soil infertile and cause habitat loss for wild animals. In addition, lava can also cause the release of hazardous materials into the environment, which can cause greater environmental damage.

The impact of environmental damage due to earthquakes is very dangerous and can cause irreplaceable losses. Environmental damage due to earthquakes can cause habitat losses for animals, infertility in the soil, and environmental pollution. Therefore, it is important to make efforts to prevent and control the impact of environmental damage due to earthquakes. These efforts include raising awareness of the impact of earthquakes, installing earthquake information delivery systems, and developing technology to minimize the impact of environmental damage. This is important to do to reduce the impact of environmental damage due to earthquakes that may occur in the future.

Can Human Manage the Earthquake?

At least very strong earthquakes occurred between the years 1900 and 2000. The largest earthquake of the 20th century, measuring 9.5 on the Richter scale, struck Chile in 1860. Earthquakes increased in frequency after that. Even though earthquakes are more frequent now than they were a century ago, nobody can stop them or come up with any strategies to stop them from happening. All that people can do to reduce losses is make an effort to adjust to earthquake conditions and keep researching earthquake incidents. And the dangers. Seismological experts have frequently offered predictions about earthquakes based on research. It’s only the human habit that’s human nature to reflect and become more watchful after the bad things happened.
