It’s taken time, but finally, people start to realize that they need to change the way they interact with the world, and more especially with the environment. Indeed, creating environmentally-friendly approaches has become a priority for all, not only in an attempt to keep the grass in our front yards green but to ensure that the grass everywhere stays green and healthy. The Chaos theory has been part of the meteorology school of thoughts since Henri Poincaré suggested during the late 19th Century that a small change could have immeasurable effects onto the climate. The idea of the butterfly effect that has a far-reaching ripple effect on events was first used by Ray Bradbury in a short story in 1952. However, the butterfly has long left Bradbury’s story to make its destructive ripple journey through our climate and civilization. Climate change is not a new concept. But in the recent years, the climatic ripples of constant levels of pollution and lack of environmental measures have created the most unnatural disasters around the world.
Did we just cause a hurricane?
Scientists all around the world have been quick to agree that climate change didn’t cause Hurricane Harvey. But they suggested that the horrifying levels of destruction it generated might have been the result of global warming. Indeed, while climate changes are not perceived as the direct causes of a hurricane, meteorologists believe that the ripple effects of global warming have turned hurricanes into destructive forces. Poised to become the most expensive disaster in American history, with $190 billion in damage to the infrastructure, it’s impossible not to feel a pan of guilt when one thinks that human lifestyle habits have potentially turned Harvey into an unnatural disaster of mass destruction. Donating to help is one solution, but it will not stop the next Harvey or Irma to hit us even worse.
The risk of megafire increases
Global warming is, to put it simply, caused by rising temperatures, which in return are the result of polluting practices. A recent study by Nature Ecology & Evolution indicates that the risk of megafires is increasing proportionally to the temperatures. In fact, the study predicts a 35% increase in the days with a danger of fire around the world. However, some regions are more likely to be touched, namely western US states, southeastern Australia, the Mediterranean regions and southern Africa. Between 2002 and 2013, the study identified 144 unnatural fire disasters caused by global warming. How many more to come before we act?
Plants in Europe equal drought in India
The sulphate emission from power plants in Europe have been linked to one of India’s most devastating unnatural drought in 2000, that has affected more than 130 million people. Indeed, scientists estimate that European emissions have caused a drop by 40% in rainfall. As the monsoon delivers over 70% of regional annual rainfall, the effects of a sudden precipitation drop were terrible for the population. This study convinced the European Union to reduce sulphur dioxide emissions actively.
How many more unnatural disasters do we need to endure as a civilization before we finally understand the damaging force of climate change? The answer is: Too many already. For now, only local petitions and actions can help to swing around the world governments and introduce protective measures
You can’t fight nature, but you can be ready for whatever she throws at you
The human race has got used to being in control of its surroundings, and yet we will never be able to truly prevent some of the most devastating catastrophes that our planet can throw our way. Yet we still strive to protect all the things we have built and worked hard for, and technology is helping us to do that on a day to day basis.
Tsunamis are a reality and we need to be prepared for them
Despite all the advances in our technology, we have not yet found ourselves able to avert the most fatal of natural disasters. The fact remains that our planet is far larger than we can possibly control and despite being considerably safer than several million years ago in the early days of the Earth’s life, it still has the capacity to be volatile and terrifying.
Some of the most devastating tsunamis in recent history have taken place in the last 60 years, with catastrophic loss of life and billions needed in humanitarian aid and reconstruction. The effects will last a lifetime for many areas as they try to recover and rebuild.
It is impossible to forget the Tohoku earthquake and subsequent tsunami in 2011. The consequences were absolutely devastating.
Striking Japan on the 11th March the earthquake reached an eye watering 9.0 magnitude, and generated a 33 feet high wall of water travelling as far as 6 miles inland. Some reports even record waves as high as 133 feet, with a 97-foot wave smashing into the city of Ofunato.
Around 25,000 people were killed or reported missing, and 125,000 buildings damaged or destroyed. But more worryingly the Fukushima I Nuclear Power Plant was also struck causing a nuclear meltdown. The disaster is recorded at the highest level of International Nuclear Event Scale. The impact of this event is still being fully understood, and radiation from the plant has been detected as much as 200 miles away, with many areas remaining uninhabitable and will be for many years to come.
The loss of human life can be staggering due to a tsunami that hits with no warning. Take for example the Boxing Day Tsunami of 2004 in the Indian Ocean. An unbelievable death toll of 230,000 was recorded across 14 countries including Indonesia, Sri Lanka, India and Thailand. The earthquake under the ocean was recorded at 9.3 magnitude, generating waves up to 93 feet high. Some waves hit land within 15 minutes, but some took as much as 7 hours.
Even those with time to evacuate were hard hit, mostly due to the complete lack of a tsunami warning system which meant very densely populated coastal areas being taken by surprise.
Early warnings save lives
By comparison, although damage to buildings and general destruction was widespread, the 2009 Samoa earthquake and tsunami saw a considerable lower death toll.
With an earthquake of 8.1 magnitude and waves reaching 45 feet high, that travelled up to a mile inland there were 189 casualties recorded. The loss of life would have been far higher if it wasn’t for the Pacific Tsunami Warning Centre which gave people time to evacuate and reach higher ground.
There are several ways in which a tsunami can be detected. From recognition of symptoms, an earthquake can be quite hard to miss, to technological warnings from tsunami detection and forecasting. These are based on a combination of data collected by environmental sensors and using that data for tsunami modelling.
For example monitoring seismic activity and the magnitude of an earthquake can give an excellent warning of tsunami potential. However, it cannot be taken in isolation. For larger earthquakes it is easier to underestimate the size of the quake, and therefore miscalculate the tsunami potential.
Rapid sea level monitoring will give the best warning
When managing the data collected, those carrying out the analysis have a hard decision. Declare a tsunami imminent, and risk a costly unnecessary evacuation, or make the decision to issue the warning to the public so that emergency plans can be activated.
They also need to be able to indicate clearly from the modelling how large the waves will be and when they will strike. Importantly they need to know when the danger will be over so that people can return safely to the evacuated areas.
The issue is that tsunami detection and forecasting requires near-real-time observations from both coastal sea level instruments and open-ocean sensors. Fundamental gaps in coverage still exist, especially in open-water. This puts at risk the ability to give warning, and the ability to learn more about the behaviour of tsunamis after the fact which will further refine the accuracy of the modelling in the future. More coverage is needed, and the durability of the equipment a key factor.
New technology paramount for the detection of tsunamis
The installation of new tsunami buoys is without doubt the next step for addressing the coverage issue, and these buoys need to be smart with built in Tsunami Early Detection and Warning System. It needs to be able to detect an event and send that information to be centrally analysed.
Pressure sensors deployed in a water depth up to 7,000 meters can detect height variations on the water surface, and in order to resist the effect of the harsh elements and environments must be of the highest quality. It is now possible to obtain floats manufactured with a closed-cell polyethylene foam sheet that prevents water absorption.
In terms of positioning and communication, all can be managed through GPS, and redundancy in place for communications via satellite, with a reaction time of less than one minute and powered by a double solar power system. These buoys are so durable they can provide much better confidence that there will be no failure of service in remote locations.
They are able to transmit a NOAA Tsunami Warning System compatible message and monitor the sea level column changes to within 1mm. This kind of monitoring will be paramount for buying enough time for evacuation and prevent the loss of life seen previously.
Starting Your Green Construction Business: Simple Guide
According to some analysts, the construction industry is booming. If you look beyond the developed world, you can see extraordinary growth rates. Developing countries, however, due to the increased industrialization of recent decades, are now facing environmental challenges, and are looking for greener construction solutions. If you are thinking about starting a company related to building and construction, you will need to think about the future trends, and make sure your company complies with current and future regulations. You will be responsible for training and policies, so it is important that you pay attention to every detail. Below you will find a few tips on starting your green construction business.
Study the Current Policies and Regulations
When starting a green construction business, you will need to thoroughly study the regulations that apply to your industry, your state, and your company structure. Different local governments might already have green policies and initiatives that will give you an advantage. On the other hand, you want to make sure that your new business will be able to meet the industry requirements when it comes to training, health and safety. Check out the requirements of the American Safety Council OSHA card to find out which qualifications your workers will need before you would create your company structure.
Invest in Technology
Green technology is constantly developing, and chances are that there are several companies on the market offering different solutions. If you would like to beat the competition, you might need to develop your own materials and work processes. If you are able to team up with engineers who are familiar with the latest trends and can spot opportunities, you can offer something unique for your business partners.
Recruit the Right People
It is also important that you find the right people for each job. Look for individuals who have similar values and visions, and embrace green ideas in the construction business. There is no way you can change the mindset of people, so it might be a good idea to provide your own training and recruit newly qualified talent, instead of workers who are already used to using traditional materials, approaches, and technologies. Your main assets will be your people, so you need to design your talent pool to meet the expectations of your customers and the needs of your company.
Develop Research Partnerships
If you don’t have the right people to research future technologies and new materials, you might decide to enter a partnership with your local college or university. If you invest in their research projects and work with them, you can take advantage of groundbreaking inventions that will help your business prosper while providing students with an opportunity to explore different opportunities to make future buildings more efficient and greener. No matter if you would like to develop your own materials or reduce the carbon footprint of your operations, you can find partners if you contact local educational institutions.
Create a Strategic Plan
No business can survive without a sound strategy. As a green construction business, you will need to integrate efficiency and carbon footprint reduction in every part of your strategic business plan. Consult with a professional advisor, and study various national and local policies that can give you ideas on creating your own competitive plan to turn future buildings greener. Check out the European green initiatives that are leading the way for the rest of the world.
When building a green organization, it is important that you adopt green policies in your company. From providing your staff with training on how to save energy and look after the environment, reduce waste, dispose of toxic materials, to targets and process manuals, there are several ways you can get your workers to jump on board and embrace your ideas.
With every business strategy, you need to develop measurable goals. You cannot simply say that you would like to reduce your company’s use of water and other natural resources: you must state by when and by how much. This will help you create targets for each worker and team, and meet the expectations of your market and your industry.
Design a Green Supply Chain
In the construction industry, it is important that you make your supply chain efficient. When you want to make your supply chain greener, it is even more important. From choosing the right suppliers to make sure that your materials are not traveling more than necessary, and you are focusing on waste reduction, to educating your workers on green and efficient practices, there are several ways you can design a supply chain that is not only good for the environment, but also for your financial budget.
When experimenting with new materials and production methods, it is important that you build strong links with government organizations, so you can be aware of the future policies and trends that will shape your industry. You can join an industry organization, and find out about the new policies and government targets as soon as possible, so you can tailor your strategy to the future policy developments.
Create a Shared Vision
When creating an innovative green construction business model, it is important that you effectively communicate your vision and mission with all stakeholders. Make sure that you are on the same page, and your suppliers, business partners, and customers are fully aware of your company’s policies and initiatives. Engage with your stakeholders by communicating your company’s plans and strategies to create more efficient buildings that serve communities better.
Some experts say that green supply chains and construction models are the future, and innovation can help organizations achieve their goals while reducing their cost and carbon footprint. If you are committed to environmental goals and would like your business model to reflect your values, you will need to build positive relationships with government organizations, employees, customers, and research facilities, so you can achieve your goals faster. An efficient business and a green supply chain can also provide you with a competitive advantage on the market.
A New Normal?: What We Need To Take Away From the Cape Town Water Crisis
The Cape Town water crisis is still very much in the news and there is a lot that needs to be learnt from what has been happening in the city where 4 million people are actively struggling to push backward Day Zero: the day when the city runs out of its water resources and water supply is shut all across the city. If you have been keeping up with the story, you’d probably know that Day Zero was set by the city’s authorities to occur early in April. With a combination of supervised action and good fortune, recent estimates have pushed the date by nearly two months, with Day Zero now set to occur some time in early June. However, it is still too early to celebrate for the citizens of Cape Town since the dams that account for the availability of water to the city are still at alarmingly low levels, with analysts wondering whether the increased scarcity of the essential natural resource should be treated as a new normal for the region or not. The mere thought of the same spells an apocalyptic warning for mankind, for it has been known for quite some time that the crisis being faced by Capetonians is not unique and soon the citizens of many major cities across the globe could be facing the same, albeit with differing levels of severity.
A Game of Numbers: What the Future Holds
We are made to learn in the earlier years of our schooling that water makes up nearly 70% of the earth’s surface but only 3% of it is freshwater, that is, water that we can drink. Couple that with the population boom witnessed over decades in developed and developing countries all over the world and you have statistics which suggest that a quarter of the largest 500 cities in the world are dealing with issues related to scarcity of water. Moreover, a warning has been issued by the United Nations World Water Development Report that by the year 2030 the global demand for drinking water would exceed the global supply by roughly 40% due to a combination of climate change, growth in population, and actions of humans: a daunting figure at the very least. Even today, more than one eighth of the human population lack access to safe drinking water, and on top of that another 2.7 billion people find water to be scarce at least one month of the year. Where this puts us 12 years down the line is by all standards a circumstance not pretty, and what this means for the cities touted to be next in line after Cape Town is pretty clear: save water as if your life depends on it, because it does, as put forth by former mayor of Cape Town Helen Zille on tackling the issue in her city.
The Next Cape Town: An Inevitability?
11 major cities have been identified as being the most likely to be affected by water crises, if any in the near future. The list also includes the south Indian city of Bangalore. Bangalore, known as technological hub or the silicon plateau of India, has often been touted as the country’s IT capital, and that is precisely why it is now so high up in the list of cities struggling to manage its water supply. Rapid property developments in the city along with the huge influx of people to fill up these spaces have put up immense pressure on the city’s antiquated plumbing and sewer systems. The whole system is so ineffective that it has been estimated through a national report itself that the city loses half of its water meant for drinking as waste. Rampant pollution over the years has just added to the huge challenge. Of all the lakes in the city, none are clean enough to be used for drinking or even bathing, and water from most of the lakes can be at best only used for industrial cooling and irrigation.
The list contains a total of 4 Asian cities out of 11 including Bangalore. The remaining three are also the capital cities of three of the largest Asian countries in terms of population: Beijing; the capital of China, Tokyo; the Japanese capital, and Jakarta; capital of Indonesia. While China is inhabited by nearly 20% of the world’s population, it is home to only 7% of the world’s reserves of fresh water. Like Bangalore, Beijing also suffers from high levels of water pollution which has attracted the attention of the Chinese government over the past few years. The remainder of the list includes the cities of Sao Paulo in Brazil, the Egyptian capital Cairo, the Russian capital of Moscow, Istanbul in Turkey, Mexico City, Miami: the only city from the US to make the list, and surprisingly even London, the capital of the United Kingdom. London receives an annual rainfall of only about 600mm and is dependent for most of its supply of water on the rivers Thames and Lea. It is estimated to face supply problems by the year 2025, and by the year 2040, London is on track to face serious supply shortages.
You Don’t Have to Wait, You Have to Start
The threats of water shortages are not new when you consider for how long the warnings have been in place, in the same places for all this while. Even if this is all new to you right now, there are lessons that have to be learnt from what is happening around us and it is the need of the hour to be aware and to be responsible for your actions and for those of others around you. We shouldn’t have to wait till the going gets as bad as it did in Cape Town when we can do better. The power to control/minimise the effects of water shortages is within you, and through your example and your actions it is extended to others around you. Take it upon yourself to be the person to lead the change, attaching all the more power to yourself as well.
