Access to safe water: Is the green revolution around the corner?

Published

on

Nature-based solutions can play an important role in improving the supply and quality of water and reducing the impact of natural disasters, according to the 2018 edition of the United Nations World Water Development Report. The study, which will be presented by Audrey Azoulay, Director-General of UNESCO, Gilbert Houngbo, Chair of UN-Water, at the 8th World Water Forum in Brasilia (Brazil), argues that reservoirs, irrigation canals and water treatment plants are not the only water management instruments at our disposal.

In 1986, the State of Rajasthan (India) experienced one of the worst droughts in its history. Over the following years, an NGO worked alongside local communities to set up water harvesting structures and regenerate soils and forests in the region. This led to a 30% increase in forest cover, groundwater levels rose by several metres and cropland productivity improved.

These measures are good examples of the nature-based solutions (NBS) advocated by the latest edition of the report, Nature-based Solutions for Water. It recognizes water not as an isolated element, but as an integral part of a complex natural process that involves evaporation, precipitation and the absorption of water through the soil. The presence and extent of vegetation cover across grasslands, wetlands and forests influences the water cycle and can be the focus for actions to improve the quantity and quality of available water.

“We need new solutions in managing water resources so as to meet emerging challenges to water security caused by population growth and climate change. If we do nothing, some five billion people will be living in areas with poor access to water by 2050. This Report proposes solutions that are based on nature to manage water better. This is a major task all of us need to accomplish together responsibly so as to avoid water related conflicts,” declared the Director-General of UNESCO.

“For too long, the world has turned first to human-built, or “grey”, infrastructure to improve water management. In so doing, it has often brushed aside traditional and Indigenous knowledge that embraces greener approaches. Three years into the 2030 Agenda for Sustainable Development, it is time for us to re-examine nature-based solutions (NBS) to help achieve water management objectives”, writes Gilbert Houngbo, Chair of UN-Water and President of the International Fund for Agricultural Development in the foreword of the report.

Focusing on ‘environmental engineering’

So-called ‘green’ infrastructure, as opposed to traditional ‘grey’ infrastructure, focuses on preserving the functions of ecosystems, both natural and built, and environmental engineering rather than civil engineering to improve the management of water resources. This has multiple applications in agriculture, the greatest consumer of water by far. Green infrastructure can help reduce pressures on land use while limiting pollution, soil erosion and water requirements by contributing to the development of more effective and economic irrigation systems, for example.

Thus, the System of Rice Intensification, originally introduced in Madagascar, helps restore the hydrological and ecological functioning of soils rather than using new crop varieties or chemical products. It enables savings of 25 to 50% in water requirements and 80 to 90% in seeds while raising paddy output by 25 to 50%, depending on the region in which it is implemented.

It is estimated that agricultural production could be increased by about 20% worldwide if greener water management practices were used. One study cited by the Report reviewed agricultural development projects in 57 low-income countries and found that using water more efficiently combined with reductions in the use of pesticides and improvements in soil cover, increased average crop yields by 79%.

Green solutions have also shown great potential in urban areas. While vegetated walls and roof gardens are perhaps the most recognizable examples, others include measures to recycle and harvest water, water retention hollows to recharge groundwater and the protection of watersheds that supply urban areas. New York City has been protecting its three largest watersheds since the late 1990s.  Disposing of the largest unfiltered water supply in the USA, the city now saves more than US$ 300 million yearly on water treatment and maintenance costs.

Faced with an ever-increasing demand for water, countries and municipalities are showing a growing interest in green solutions. China, for example, recently initiated a project entitled “Sponge City” to improve water availability in urban settlements. By 2020, it will build 16 pilot Sponge Cities across the country. Their goal is to recycle 70% of rainwater through greater soil permeation, retention and storage, water purification and the restoration of adjacent wetlands.

The importance of wetlands

Wetlands only cover about 2.6 % of the planet but play a disproportionately large role in hydrology. They directly impact water quality by filtering toxic substances from pesticides, industrial and mining discharges.

There is evidence that wetlands alone can remove 20 to 60% of metals in water and trap 80 to 90% of sediment from runoff. Some countries have even created wetlands to treat industrial wastewater, at least partially. Over recent years, Ukraine, for example, has been experimenting artificial wetlands to filter some pharmaceutical products from wastewater.

However, ecosystems alone cannot perform to totality of water treatment functions. They cannot filter out all types toxic substances discharged into the water and their capacity has limits. There are tipping points beyond which the negative impacts of contaminant loading on an ecosystem becomes irreversible, hence the need to recognize thresholds and manage ecosystems accordingly.

Mitigating risks from natural disasters

Wetlands also act as natural barriers that soak up and capture rainwater limiting soil erosion and the impacts of certain natural disasters such as floods. With climate change, experts predict that there will be an increase in the frequency and intensity of natural disasters.

Some countries have already started taking precautions. For example, Chile announced measures to protect its coastal wetlands after the  tsunami of 2010. The State of Louisiana (USA) created the Coastal Protection and Restoration Authority following Hurricane Katrina (2005), whose devastating impact was magnified by the degradation of wetlands in the Mississippi Delta.

Nevertheless, the use of nature-based solutions remains marginal and almost all investments are still channelled to grey infrastructure projects. Yet, to satisfy the ever-growing demand for water, green infrastructure appears to be a promising solution complementing traditional approaches. The authors of the report therefore call for greater balance between the two, especially given that nature-based solutions are best aligned with the Sustainable Development Goals adopted by the United Nations in 2015.  Coordinated by the UN World Water Assessment Programme of UNESCO, the United Nations World Water Development Report is is the fruit of collaboration between the 31 United Nations entities and 39 international partners that comprise UN-Water. Its publication coincides with World Water Day, celebrated every year on 22 March.

Squid game is a current Netflix’s trend series and no one can escape from its influence. The world has Squid game fever now and there are a lot of people who want to partake and experience being in these games. People are lining up to try the popular games in the show and the Squid game’s challenges are piling up in social media and YouTube. This show is climbing up to the first place and achieving global popularity.

In the Squid game, the people who have debts are trying hard in playing the children’s games to win the billion-prize money but the punishment is death. The struggle and the poverty are focused in this series. Besides, it highlights the greed of the people and how it can awaken the devil’s side of human beings. The friendships, sympathy and care can be destroyed easily because of the greed for surviving and money. Apparently, this show is giving a special taste to the audience by the direct approach about our society and socioeconomic conditions. Therefore, it is no wonder that this gains a lot of popularity and becomes Netflix’s most-watched series in history.

Since Squid game wave is striking hard, people are addicted to the show and their willingness to try out the games of this show are unstoppable. So, this time can these passionate audiences participate in the Squid game competition for the sake of our planet? Nowadays, the state of our planet is serious and encountering a plethora of threats; pollution of air and water, ozone layer depletion, climate change, rising sea levels, land degradation, deforestation, loss of biodiversity and so on. 

Due to these environmental concerns, a lot of groups are rising up to spread awareness within the public. These socially conscious groups around the world try hard to inform how the single action of the people can impact the earth. Not only to protect the environment but also to reduce the existing environmental issues, the people from different backgrounds, societies and places have to work together. Although plenty of people are now concerned for their home planet and searching for the answer to solve these issues, educating the public to increase more awareness and attention still needs more room to develop.

To promote environmental awareness and actions to help our planet, the growth of the Squid game can play a perfect role. The unbeatable amount of Squid games addicted fans who are also concerned for the state of the planet can be used in encouraging the public more for the current issues of the earth. Let them play these trend games that they are dying to play and at the same time, the promotion for the actions to preserve the earth will be done.

Creating the competition which inspire Squid game series for our home planet

Type of games and the Rules

Just like in the Squid game series, in this competition, there will be traditional children’s games which were popular in the past. But this time, the games will be collected from various countries. Therefore, the contestants can experience various cultures, explore new things and as a consequence, they will feel connected to each other. Besides these traditional games, there will be games that can help to reduce the carbon footprints such as planting the trees as much as they can in the given time, creating innovative staffs by recycling or reusing the materials and so on. The prime rule for this competition is that the player cannot quit till the game ends and they will have to agree to take the punishment no matter what. And manipulation to each other is not allowed and all the players will be equally treated while in the games.

Host and sponsors

The international organizations such as WWF, IUCN, UNESCO, UN, ASEAN, ADB, etc can be the host in this game. Since these organizations are helping to identify the environmental problems and supporting the protection, they can be the best candidate to be a host in the competition. Along with them, the big corporations who are embracing sustainability can be the sponsors, in other words, they will take the role of VIPs just like in the Squid game series. As the businesses can make greater profits and create better images by considering the economy, social and environment in operating their businesses. Being the sponsors in this game will help them in implementing the better CSR programs and pursuing sustainability. This is one of the best ways to acquire the public’s attention, also loyal customers and as a result, their brand image and competitive advantage will also be improved.

Players

Who will get the invitation for this game?

A group of socially conscious, young generations and also the people who want to experience the games can be the players in this competition. Most of the youths are worried about the future of the planet and they are concerned about the impacts of the environmental issues. They want to change their lifestyles to be more environmentally friendly compared to the older generations. Due to this competition, the adults can have a chance to remember their nostalgic childhood times and the young can experience these old games while they can make effective things for the planet.

Prize

The prize is one of the incentives to stimulate the people to play in this game. The bitter truth is one of the powerful incentives is money. A group of winners will get the money to invest in the environmental projects. Frankly, to protect our environment and planet, billion dollars is one of the requirements.

Punishment

As the players are competing for the sake of the earth, the punishment will definitely not be death. But instead, the players who will get eliminated from the games will have to spend their times at the special place for several days. That special place is located in one of the biggest landfill sites. Losers of this competition have to work in that place and they will have to help in the disposal services.

To conclude, if this competition actually happens in the future, it will bring certain benefits for the environment, society and businesses. So, why do not we inspire this current most-watched series “Squid game” to spread awareness and encourage the people to save the planet, Earth. Let’s give a chance for the people to play in their favorite childhood’s games, be green and save our home.

Climate change and global challenges

Published

on

The whole world has been severely affected by climate change and the Covid-19 epidemic. The natural character of the whole world has also changed due to the rise in global temperature. Given the current situation, all the people of the world are in a state of panic about the horrors of the coronavirus. The world has been devastated by hundreds of disasters since the 1960s. More than 50 million people have become destitute. Many people have died. And most of the disasters are accompanied by constant climate change.

In 2020, 4 crore people became homeless due to deteriorating weather and climate change. At the same time, the adverse effects of the weather are becoming more extreme due to climate change from this year. This year it will break the record and stand at 5 crore. Many people have to leave their country. This number is double the current refugee population in the world. Not just any particular country or people, people all over the world are facing the harmful effects of climate change. Especially in the last 20 years, this effect has spread from Asia, Europe, Africa to the Americas.

Increasing use of fossil fuels is warming the weather, forcing more people to flee their homes due to unexpected floods or storms. Besides, factors like crop damage and drought are also making this trend more evident. Politicians in rich countries are fearful of increasing pressure on their country’s infrastructure due to the influx of environmental refugees from other countries.

Carbon emissions play the biggest role in climate change. Low-income countries are also deprived of 100 billion a year in promised compensation for carbon emissions. Asia has the highest number of people displaced due to environmental reasons. In countries such as China, India, Bangladesh, Vietnam, the Philippines and Indonesia, millions of people live in low-lying coastal areas or in delta-adjacent areas. More and more people are at risk of flooding due to population growth and urbanization, and the rapid rise in sea level is being added to this.

People have already witnessed extreme weather, drought or heavy rains, cyclones.  That is to say, the destructive form of climate and nature is gradually becoming manifest. Mankind is being blamed for this hostile behavior of nature. People are taking care of nature in many ways. Rivers are being occupied and the mountains are being cut indiscriminately. Houses are being built on agricultural land. In this way, oppression on nature is going on in various ways, due to which nature is becoming hostile. We are ruining all our own achievements. As a result, there has been severe inflammation.

The world’s population is constantly growing. There is no end to the discussion and criticism about population growth. It is time to take stock of what new steps can be taken or how human suffering can be reduced. With the increase in population, new problems have been added. It may seem unbelievable but it is true that every day around 25,000 people in the world die due to eating habits and malnutrition. In addition, the world is facing many adverse reactions including shortage of potable water, air toxicity, depletion of resources, housing problems and the destruction of the Ozone layer.

At the root of this is population growth. The temperature in the capital Dhaka has risen due to rapid population growth. A study has identified 25 high-risk areas in Dhaka as a result of rising temperatures. These areas have been named ‘Hit Island’. The performance of the people of this area is decreasing day by day with the increase of various diseases.

Assistance is needed to increase the capacity of CVF countries to deal with the dual threat of epidemics and disasters, especially those affected by the increased frequency of climate-related disasters. Climate-risk countries contribute the least to global greenhouse gas emissions, but they suffer the most. 2021 is a very important year for climate issues as the United States returns to the Paris Agreement. The COP-26 conference on climate change in Scotland next November is expected to yield some good results on climate change. The main goal of COP-26 is to address the impact of climate change and to educate the world about its harmful effects. Bangladesh has also participated in this climate change prevention project.

In ancient times there was a close relationship between man and nature. Ever since man came in contact with civilization, he has learned to strike at nature. Over time, man began to wreak havoc on nature. The problem of environmental pollution is increasing day by day. The trees were not spared from the victims of cruelty. As a result, fear is constantly concentrated in our habitable world. We look for different ways to get rid of it. But if we let nature be like that, we would not have to suffer this consequence in our lifetime.

Blinded by the fascination of speed, people have cut down the forest and set up houses, sometimes they have driven away the animals there. In recent times, mountains are being cut down and forests are being cleared somewhere. Deforestation is endangering the lives of many people. Even though the seasons are changing, these incidents add to our anxiety. But trees can be very resistant to prevent global warming. If the environment does not survive, the problems of the world will intensify. Animals, human beings will face loss of everything. The main reason is the indifference of the people.

 A closer look reveals that this apathy has a significant effect on the depraved market economy. Rivers, hills, soils, forests are all instruments of income growth in the eyes of that market. In order to earn income from these sources, natural resources are being destroyed, centuries-old trees are losing their lives or the source of the boundless beauty of nature is being endangered. In the past, there was a connection between man and nature, which is why in many places forests have survived because those who grew up in contact with plants can realize the contact with nature by finding ways to do the necessary work without harming the plants.

Climate change is responsible for recent disasters. We have to fight hard to save the world from increasing global warming. World leaders must take strong action, including global initiatives, to leave a sustainable future for the next generation. The international community has a special responsibility to assist countries at risk of climate change in their adaptation and mitigation efforts.

It’s not fair to single out the five countries in the Greta Thunberg UN children-climate case

Published

on

The Greta Thunberg UN case decision just came out today. You might remember that back in 2019, Greta and other children brought a headline case before the UN to prove that climate change affects children’s rights, and it’s a hard issue of law and rights — something that has been long resisted in the area of human rights law when it comes to the environment. The environment has always been one of those peripheral issues for human rights law and that’s why today’s decision is groundbreaking. In a historic ruling that came out today, the UN Child Rights Committee has found that a State party can be held responsible for the negative impact of its carbon emissions on the rights of children both within and outside its territory.

The countries that are bearing the international public slap in the face in this case, however, (Argentina, Brazil, France, Germany, and Turkey) are not the biggest emitters and polluters. They were selected as a target of the case not for the worst climate impacts, but simply because they have ratified the additional Protocol of the UN Child Rights Convention, so a case against them can be brought; the biggest emitters haven’t. So it’s a bit like a “catch whoever you can”, and that should be born in mind in the discussion.

The countries in the UN Greta case are the classical international law countries (Europe and Latin America) who have agreed that their human rights practices can be reviewed and challenged. The biggest carbon emitters, on the other hand, haven’t agreed to accept cases.The US hasn’t even ratified the Child Rights Convention, as the only country in the world, let alone the Additional Protocol for direct cases.

The case is very important as a test case and one which develops the nexus between human rights law and climate. It develops the principles of the reasoning and the legal parameters — that’s the take-away. We should remember that the five singled out countries are not the bad guys when it comes to climate change.
