Towards Sustainable Biomass Energy

biomass-balesBiomass is one of the oldest and simplest ways of getting heat and energy, and it’s starting to make a comeback due to its status as renewable resource. Some, however, aren’t so sure that using more of it would be good for our environment. So, how sustainable is biomass energy really?

What is Biomass?

Biomass is organic material from plants and animals. It naturally contains energy because plants absorb it from the sun through photosynthesis. When you burn biomass, it releases that energy. It’s also sometimes converted into a liquid or gas form before it is burned.

Biomass includes a wide variety of materials but includes:

  • Wood and wood processing waste
  • Agricultural crops
  • Garbage made up of food, yard and wood waste
  • Animal manure and human sewage

About five percent of the United States’ energy comes from biomass. Biomass fuel products such as ethanol make up about 48 percent of that five percent while wood makes up about 41 percent and municipal waste accounts for around 11 percent.

The Benefits of Biomass

Biomass is a renewable resource because the plants that store the energy released when it is burned can be regrown continuously. In theory, if you planted the same amount of vegetation that you burned, it would be carbon neutral because the plants would absorb all of the carbon released. Doing this is, however, much easier said than done.

Another potential is that it serves as a use for waste materials that have are already been created. It adds value to what otherwise would be purely waste.

Additionally, many forms of biomass are also relatively low-tech energy sources, so they may be useful, or even required for older buildings that need an electrical renovation.

Drawbacks of Biomass

A major drawback of using biomass fuel is that it is not an efficient process. In fact, burning it can release even more carbon dioxide than burning the same amount of a fossil fuel.

While you can replenish the organic matter you burn, doing so requires complex crop or forest management and the use of a large amount of land.  Also, some biomass, such as wood, takes a long time to grow back. This amounts to a delay in carbon absorption. Additionally, the harvesting of biomass will likely involve some sort of emissions.

 Is it Sustainable?

So, is biomass energy sustainable? Measuring the environmental impacts of biomass fuel use has proven to be complex due to the high number of variables, which has led to a lot of disagreement about this question.

Some assert that biomass use cannot be carbon neutral, because even if you burned and planted the same amount of organic matter, harvesting it would still result in some emissions. This could perhaps be avoided if you used renewable energy to harvest it. A continuous supply of biomass would likely require it to be transported long distances, worsening the challenge of going carbon neutral.

With careful planning, responsible land management and environmentally friendly harvesting and distribution, biomass could be close to, if not entirely, carbon neutral and sustainable. Given our reliance on fossil fuels, high energy consumption levels and the limited availability of land and other resources, this would be an immense challenge to undertake and require a complete overhaul of our energy use.

How to Improve the Biomass Industry

Biomass could emerge as a major solution to our energy and sustainability issues, but it isn’t likely to be a comprehensive solution. There are some things we can do, though, to make biomass use more sustainable when we do use it.

  • Source locally: Using biomass that comes from the local area reduces the impact of distributing it.
  • Clean distribution: If you do transport biofuel long distances, using an electric or hybrid vehicles powered largely by clean energy would be the most eco-friendly way to do it. This also applies to transporting it short distances.

Measuring the environmental impacts of biomass fuel use is complex due to high number of variables

  • Clean harvesting: Using environmentally friendly, non-emitting means of harvesting can greatly reduce the impact of using biomass. This might also involve electric vehicles.
  • Manage land sustainably: For biomass to be healthy for the ecosystem, you must manage land used to grow it with responsible farming practices.
  • Focus on waste: Waste is likely the most environmentally friendly form of biomass because it uses materials that would otherwise simply decompose and doesn’t require you to grow any new resources for your fuel or energy needs.

Is biomass energy sustainable? It has the potential to be, but doing so would be quite complex and require quite a bit of resources. Any easier way to address the problem is to look at small areas of land and portions of energy use first. First, make that sustainable and then we may be able to expand that model on to a broader scale.

Ingredients of Environmental Sustainability

Global interest in environmental sustainability is on the rise. Businesses and individuals are making efforts to engage in more environmentally conscious practices, thanks in part to a growing worldwide population and dwindling natural resources. Ultimately, sustainability is the practice of finding long-lasting methods of maintaining our existing quality of life while still preserving the environment and natural resources.

Proponents must consider all aspects of environmental sustainability for it be successful. Additionally, eco-conscious thought must be applied to multiple professions to achieve deep-rooted results. Here are three ingredients to ensure the continued success of environmental sustainability.

Economic Incentives

Everyone knows change can be difficult. Making the shift toward more eco-friendly practices is no different. One way to initiate this change is through financial incentives. Money is an essential factor for families and companies. If sustainable options and practices are too expensive the majority of the population can’t afford to implement them, the environmentally-conscious movement will come grinding to a halt.

Environmentally-friendly technology often carries higher upfront costs but pays off through long-term benefits, both to the environment and to individuals. Additionally, companies that invest in environmentally conscious technology can potentially market to a broader range of consumers with similar interests and values.

When considering options to follow more sustainable practices, consumers need to set specific goals they would like to achieve and define their plan of action. This will also help maintain perspective and keep the focus on the long-term incentives, which will keep everyone motivated to continue down the road to sustainability.

Environmental Protection

Another key factor in environmental sustainability is protecting and preserving the environment. Part of this practice includes sustainable use and management procedures. While specific materials may be renewable over time, overuse can deplete these resources and lead to shortages. Industry professionals must give careful consideration to planning how, when and in what quantity resources will be used.

Surprisingly, several sustainable methods exist to renew depleted environmental resources in a fast and environmentally conscious manner. Agricultural practices often strip fields of necessary minerals and nutrients while leaving behind harmful inorganic residuals from fertilizers.

Naturally occurring microorganisms will eventually restore the soil’s nutrients and neutralize noxious compounds, though this process takes a long time. Bioremediation can expedite this process. Industry professionals can introduce higher numbers of the naturally occurring microbes and then create their optimal living conditions by varying the amount of water and food they have available.

Once the harmful pollutants are neutralized, farmers can resume planting operations. In addition to bioremediation, sustainable agricultural practices include rotating crops and using cover crops. Rotating crops and using cover crops can help reduce the occurrence of weeds and the impact of pests. In turn, farmers can use less fertilizer and maintain soil health for more extended periods.

Fostering interest in sustainability at a young age will encourage future leaders

Education

Without proper education, the general public won’t understand the importance of sustainability. This may lead to a decreased demand for sustainable products and procedures, which will foster growth in non-sustainable markets and practices. Future generations will then be left with the task of preserving and repairing the environment.

Fostering interest in sustainability at a young age will encourage future leaders to create innovative solutions to meet the current demands of society through unconventional and eco-conscious means. The future youth will also need the proper educational background to develop the tools they need to cultivate these solutions.

Environmental education also helps adults understand the impact their choices have on themselves and society. Uneducated adults may not recognize their choices to pollute or use toxic chemicals are degrading the local water supply for their neighbors or are harmful to their health. Once they understand the full weight of their decisions, they will be able to make the most informed choices.

With proper management and forethought, environmental sustainability can be fully achievable in our society today.

Home Renovation Can Improve Energy Efficiency

There is almost nothing more satisfying than a clean, fresh, and sustainable home. You may think that renovating your home is a hassle, not to mention expensive, but there are plenty of small changes that can make a home really feel like it’s yours. Something as simple as a new garage door, or a small solar panel can bring personality and life to your home while saving energy and giving you a boost of pride for your house.

Doors and Windows

When thinking about renovating your house, you probably think, new basement, new roofing, and much more expensive and time consuming projects. But do not write off home improvement just yet! There are plenty of small changes that can make a huge difference to the style of your home and even boost its overall value.

Keeping your home well insulated is a wonderful option.

Doors and windows play a huge part in energy efficiency as air enters and escapes your home. This makes these options a great place to start as they add a personal flair to your home’s look as well as being environmentally friendly. Below is a short list of these renovations you may not have thought about.

Garage Doors

When thinking about the outdoor curb appeal of your home, an often overlooked detail is the garage. This may seem silly but just think about how much visual space your garage door or doors take up.

A new or refurbished garage door can not only up the style and personality of your home, but can make your home more energy efficient and secure. And with companies like CSSGarageDoors there are so many styles to choose from.

Front Door

A unique front door also helps your house stand out and adds your own personal touch to your home. Keep in mind the style of your garage doors and make sure your other doors do not clash. Replacing old front doors can also save you money and energy, as air often escapes from unseen cracks in old doors and windows.

There are hundreds of style choices to choose from, and many energy efficient sustainable options too. Not only will this give your home an instant personality boost, it will raise the value of your home significantly.

Windows

While this one may be a little more on the pricey side of renovations, it is yet another example of boosting your homes personality, value, and efficiency. Not only can you choose from styles of windows, you can choose how you want the glass and frames to make them custom just for you and your home.

New windows will save you money on heating and air and some even keep out the noises of busy streets or noisy neighbors. Depending on the climate and place you live, these replacements could be a life saver. Lowes has an excellent selection of beautiful window and door replacements.

Energy Efficiency and Sustainability

While improving the overall look of your home can give you a sense of personal pride in your home, less visible but sustainable options can give you comfort and help the planet. If you want to live more sustainably but do not have the funds to build a whole new eco-friendly home, there are small changes that can boost your home’s energy efficiency and sustainability. Below is a short list of options to improve your home from the inside out.

Tankless Water Heaters

Water heaters are probably something you do not often think about. However, that tank that sits in your garage or basement is constantly using energy. Even when you are not using your hot water, the tank is busy working away using energy and costing you money. Switching to a tankless or on-demand water heater means that it will only be using energy when you need it.

Solar Panels

Solar panels are becoming better and better, and adding one to your homes exterior no longer seems like a dream. While there is a lot to consider before installing solar panels, they can be an amazing way to reduce energy and a great investment.

Although solar panels can last for up to 30 years, you do not need to be afraid of wasting money when you move as they can increase the value of your home significantly. You can also get a sizeable tax return for installing solar panels, so it is a great option to look at for sustainable living.

Biogas in Agriculture Sector in India: Key Challenges

Although the conversion of agriculture waste – cattle dung and crop residues –  to biogas and digested slurry is an established and well-proven technology, it has been under-used, probably because until recently, firewood was easily available and chemical fertilizer was relatively affordable to most of the farmers in India.

The National Biogas and Manure Management Programme (NBMMP) was put in place to lower the environmental degradation and prevent greenhouse gas emissions, like carbon dioxide and methane, into the atmosphere. However, this objective of the program is less likely to motivate the farmers and their families to install biogas plants.

This program rolled out by Ministry of Non-Conventional Energy Sources (now Ministry of New and Renewable Energy), New Delhi, with heavy subsidies for family-type biogas plants to increase adoption, was successful with lakhs of biogas plants being installed across the country till now.

It was realised that due to poor dissemination of information and unsatisfactory communication about the plant operation & application of the digested biogas slurry, and unable to perceive the return in terms of value resulted in discontinuation of lakhs of biogas plants across the country.

The entire biogas technology marketing efforts failed to highlight major advantage – an increased revenue from agriculture with the use of high quality and a low-cost homegrown digested biogas slurry as fertiliser. Another advantage was to help farmers’ understand that their land quality and output per acre will increase over the years by the use of digested biogas slurry which has been degraded from the rampant use of chemical fertiliser and pesticides.

Challenges to be addressed

The farmer’s communities today are required to made to understand that their revenue from agriculture is decreasing year on year due to increasing deforestation, degradation of land quality, rampant use of chemical fertiliser and pesticides, lack of farm cattle, injudicious use of water for irrigation, and use heavy vehicles for ploughing.

These ill-advised decisions have made the farmers poorer, impacted the health of their families and the rural environment of villages. The years ahead are crucial if this trend is not reversed.

Unending benefits of biogas technology

Most of the rural and semi-urban areas have a poor perception of the Anaerobic Digestion (or biogas or biomethanation) technology. This technology offers benefits to all spheres of society but have a particular emphasis on the needs of the farmers in rural areas.

Farmers with dairy animals generally have free access to animal waste (dung), which provide input feed for the biogas digesters. Normally, these farmers stock-pile the dung obtained from their cattle as a plant fertilizer, but this has lower nitrogen content than the digested biogas slurry created by the biogas digestion process, which is odorless and makes a better fertilizer to substitute chemical fertilizers. They can use the gas for cooking or heating, for running power generators. The biogas technology helps farmers reduce their burden to buy LPG and harmful chemical fertilizers and pesticides.

In short, biogas technology is an integrated solution for sustainable agriculture, improving health and lowering environment degradation.

The promise of biogas technology

Biogas technology can help in the following manner:

  • Enhance bio-security for dairy animals – being fully fermented, bio-slurry is odorless and does not attract flies, repels termites and pests that are attracted to raw dung.
  • Provides high quality and low-cost homegrown fertiliser for sustainable agriculture.
  • Reduce energy poverty and ensure energy security.
  • Digested biogas slurry is an excellent soil conditioner with humic acid.
  • Save time for women for education and livelihood activities.
  • Increase forest cover as less firewood would be needed on a daily basis.
  • Reduce weed growth

Importance of Government Efforts

The agriculture sector is playing a major role in India economy and it comprises a huge vote bank. Our government has launched various initiatives like GOBAR-DHAN (Galvanizing Organic Bio-Agro Resources Dhan), Sustainable Alternative towards Affordable Transportation (SATAT), and New National Biogas and Organic Manure Programme (NNBOMP) in attempt to revive interest in biogas technology for farmers and entrepreneurs.

rice-straw-biogas

Agricultural residues, such as rice straw, are an important carbon source for anaerobic digestion

These initiatives are aimed at developmental efforts that would benefit the farmers, vehicle-users, and entrepreneurs. These initiatives also hold a great promise for efficient solid waste management and tackling problems of indoor air pollution caused by use of firewood, deforestation and methane gas release in the atmosphere due to open piling of cattle dung.

These initiatives aren’t marketing the value which solves a major challenge – degradation of agriculture land for farming in rural India. The initiative and efforts are majorly focused on waste management, environment and towards behavioral change. These changes are of global importance and can be managed effortlessly by generating tangible results for farmers.

India has an aspiring young workforce which is moving to urban settlements in hope for better opportunities, therefore, productivity and revenue from agriculture needs to grow. The biogas technology can restore agriculture productivity and strengthen revenue to make it attractive.

Green Financing as a Tool for Sustainable Development

Climate change and environmental damage due to human activity is now an accepted fact. Thankfully, investors and financial organizations are finally recognizing the importance of changing our ways and investing in sustainable technologies. This type of green financing is allowing them to recognize the environmental and financial benefits of these new technologies.

Green SMEs

Today we’ll cover how green financing can be used to encourage sustainable development on the company and individual scale.

What is Green Financing?

Green financing at its most basic is the use of public money, private loans, and micro-lending to support sustainability. The goal of green financing is to encourage change in favor of environmentally friendly actions.

It can be everything from large scale investment into tools to fight climate change all the way down to small personal online loans next day for consumers. This allows everyone to do their part to help promote sustainability.

Most green loans are tied to specific metrics. They can cover everything from large companies to the type of washing machine you purchase.

How Green Financing Works

Like any financial product there’s a huge range of green financing options. One of the most prominent examples is sustainability-focused venture capital firms.

These VC firms search for early-stage startups with a focus on the environment. They combine their financial goals together with their vision of what the planet should be.

By far the largest subset of their focus is on reducing our dependence on fossil fuels and fighting emissions. On the individual scale there’s lots of focus on lowering your carbon footprint.

Lots of loans are specifically put in place for people to buy green friendly products.

What Qualifies as Sustainable Projects

There are tons of early to middle stage startups with a sustainability focus. These are all key examples of large scale green financing.

Many of the projects are receiving the most funding focus on clean power and the use of renewables. Think electric vehicles, charging stations, battery enhancements, solar and wind energy, etc.

Another major sector is advancements in water purification, desalination, and ocean cleanup. These also include interesting projects like advanced agriculture and reducing the overall reliance on irrigation.

For individuals most green financing is related to their home or vehicle. There are lots of online loans same day available for things like energy efficient appliances or vehicles. These often combine with tax credits as a way to encourage people to reduce their overall energy consumption habits.

One of the biggest uses of green financing by individuals is to buy an electric or hybrid car. This reduces the often high price of these advanced vehicles and makes it more attractive to drive one.

Another big one is to finance green renovations to your home. If you want to improve your home’s insulation or add on a solar power system there’s ample funding available. These often combine with tax breaks and utility buyback programs to make it an even more attractive option.

Turnaround Time for Financing Decisions

With venture capital the around time for high-quality opportunities is often very rapid. If you have a great model for your business and can show a clear return potential they’ll often respond within just a few days.

For green financing other factors come into play. Most green venture capital funds have very specific requirements on what they’re looking for. Do your research before contacting them and make sure you represent what they’re looking for.

How much you should reasonably expect to receive depends on how far along in the process you are. Seed stage companies generally receive less than $1 million. Series A and Series B can receive more but still much less than more mature companies with proven revenue and a customer base.

For personal green loans the turnaround is often much faster. Many companies offer instant or at least same day approval for well qualified borrowers. This gives you the freedom to begin making your plans immediately after receiving funds.

Make Changes Today

The clock is running down on our ability to head off the effects of climate change. Green financing is one of the best ways to make changes in the world and your life. It funds the technology that may save humanity and allows individuals to make changes to their home and car to reduce their own carbon footprint.

An Easy Guide to Make Your Business Sustainable

The adoption of sustainable practices is an opportunity for growth, but it also presents a challenge. Though you’ll eventually enjoy the economic and environmental benefits of your changes, implementing them takes commitment. You need to approach the transition with subtlety.

So what are the main points to keep in mind as you continue? What are practical strategies to reduce carbon emissions and excessive commercial waste? We’ll answer those questions and others like them, providing an easy guide for professionals who want to improve their standard of sustainability.

1. Assign a Sustainability Team Lead

One of the key factors in your success is communication. You need every employee to understand and accept your proposed changes, and that coordination is no small responsibility. If you’re going to increase sustainability in your workplace, you’ll need the assistance of a sustainability team lead.

Their role is to share your objectives with other employees and encourage them to adapt their behavior. They serve as an advocate for your new policies, putting them into action and helping others do the same. In short, your sustainability team lead will facilitate cooperation.

2. Invest in Practical Adjustments

When you’re operating a business, your bottom line is your top priority. You can’t afford to make changes if they compromise your profitability. Fortunately, you don’t need to make that kind of sacrifice, as certain practices are beneficial for both the environment and your expenses.

As an example, you can digitize documents to limit paper waste and lower the costs of printing and ink. You can also connect a group of devices to a single power strip, then turn it off when you leave the office. It’s a simple adjustment which will increase the lifespan of your devices and reduce e-waste.

3. Maintain Careful Record-Keeping

Over the past two years, many companies have engaged in the practice of sustainability reporting. Investors are starting to ask for this type of report, and if business owners are unable to provide it, they may encounter issues. Naturally, you need to give thought to record-keeping.

Are you documenting your changes? Do you have the necessary information from project and property managers? Investors need more than a promise to feel secure in your company’s improvements, and you can instill confidence when you offer reports with the relevant data.

4. Work With Similar Companies

Many companies have made it their goal to “go green,” and you should seek their support. Check for a list of green vendors in your area, and when you find one that meets your needs, reach out. You’ll come across sustainable alternatives for many products and services you currently depend on.

You may benefit from an eco-friendly cleaning service if your present service isn’t adequate. On a smaller scale, you can purchase business cards from a company that uses recycled materials. The point remains the same: You have options, and you should explore them.

5. Keep Convenience in Mind

As you modify your office, consider the convenience of your changes. An employee is far more likely to recycle paper and plastic products when they can easily access a recycling bin. If you’ve placed the bin in a location that doesn’t see much foot traffic, you’re not going to get the results you want.

Naturally, the ideal place for a recycling bin is the lunchroom or a similar area where your employees tend to congregate. The choice to recycle shouldn’t take more effort than the choice to use a conventional bin. Make both bins available to employees and trust them to make the correct decision.

6. Start Planning Today

Sustainability isn’t as simple as it first seems. A business owner may have good intentions, but unless they take time to prepare, their initiative won’t yield the desired results. With that in mind, review the steps in this guide and start planning your sustainability program today.

Tackling China’s Smog Problem with Renewable Energy

smog-chinaChina is currently facing serious environmental problems, with potentially few solutions. Currently, this is mostly taking the form of serious smog issues plaguing North China, with more than 24 cities on red alert. However, with airports being shut down due to lacking visibility and the economy of China being heavily disrupted, action needs to be taken to solve this serious smog problem.

While limited action has been taken, perhaps renewable energy is the key to cutting down China’s smog.

How Bad Is the Problem?

The smog problem in China has become increasing worse from 2015 to 2017, with more than 90 micrograms of pollution per meter squared. These levels of air pollution are similar to the levels recorded previous to 2014, when the Chinese premier declared a war on pollution due to the health dangers posed by rising air pollution levels.

However, since 2015, levels of air pollution have risen once again. This pollution has had hard hitting effects on urban areas, especially the Chinese capital Beijing, and has caused widespread disruption to the lives of Chinese citizens and economy of the country.

The air pollution leads to the cities becoming hotter than ever. Urban Heat Island effect, which refers to buildings absorbing the sun’s heat well, is exacerbated by the smog. In fact, a car in the heat can reach temperatures of 114 degrees Fahrenheit after just 20 minutes, making travelling on hot days nearly unbearable for any living creature. In order to decrease the heated condition of China, it is essential to decrease the amount of smog covering the cities.

What Has the Chinese Government Done?

The Chinese government has taken limited action in an attempt to minimize the air pollution being created in the country. This includes the Atmospheric Pollution Prevention Plan, which acknowledged the danger posed by air pollution levels and aimed to reduce coal usage in urban areas like Beijing.

However, this is not representative of the main action the government has taken. Primarily, the Chinese government has focused on individual areas and attempting to reduce local pollution levels through efficient coal burning and banning the burning of waste materials, especially on farms. These solutions, while effective on a short-term basis, are not all that is needed, though.

Investment in renewables can reduce China's dependence on coal for power generation

Investment in renewables can reduce China’s dependence on coal for power generation

China needs to reduce its overall usage of coal produced energy, which currently stands at 64 percent of total energy consumption. While this has already been happening in China, the further introduction of renewable energy could be of great help to China’s pollution levels.

How Could Renewable Energy Help?

Many people believe renewable energy to be a small affair, something undertaken by the Western world in a vain attempt to reduce our collective guilt concerning climate change and wastage levels. This is simply not the case. Renewable energy is a $120 billion industry that receives investment and application across the world. This includes solar energy, waste-to-energy technology, wind energy, hydroelectric energy and many more attempts to reduce overall energy usage.

Through investment in renewable energy, China could reduce its dependence on coal and increase the efficiency of its energy production and economy. Smog is directly created by China’s use of coal for its energy production, and by investing in other renewable means, China can simultaneously improve its health situation.

In fact, the obviously positive nature of investment in renewable energy can be clearly seen through the Chinese government’s already existing plans to further incorporate it into the economy. In the five-year plan announced in 2016, the Chinese government explicitly stated it would decrease air pollution levels through investment in wind, solar and biomass energy production technologies.

While the plans additionally included investment in making the coal industry more efficient and reducing emissions on an industrial and commercial level, clearly renewable energy is believed to be a valid alternative energy source.

Overall, it is clear that renewable energy can certainly help with China’s serious smog problem. Whether this should be in tangent with further investment in the coal industry or necessitate the end of widespread coal usage in China is still a question for debate.

Why We Need to Take Climate Change Seriously

Climate change involves and impacts every system within the planet, from ecosystems to fresh water distribution. It’s infinitely complex. But while many causes are still unknown, we do know that the earth’s temperature is rising and that human activity is contributing to the temperature spike noted since with the Industrial Revolution.

While common climate change culprits include increased use of fossil fuels and rising levels of CO2, other causes are lesser known. For example, methane gas from biodegradable waste is a major greenhouse gas. Scientists now say biodegradable waste in dumpsites is contributing more methane to the atmosphere than they thought. Identifying contributors like this helps us make smart choices when it comes to things like waste management.

With that in mind, here are some other causes and implications of climate change that make it something we should take seriously.

Overpopulation is a Bigger Cause Than You Think

It’s been found that human overpopulation and climate change are scientifically linked. As the influential political economist Robert Malthus noted, “The power of population is indefinitely greater than the power in the earth to produce subsistence for man.” In other words, it’s much easier to make new humans than it is to support them. The increase in population brings more demand for natural resources, more land dedicated to farming, more deforestation, and elevated carbon emissions. Population growth and climate change are a perfect feedback loop.

But the implications of maintaining this system are disastrous for the planet and human civilizations. The demand for natural resources to support 7.5 billion people already exceeds what the planet can provide. Experts estimate that humans currently use the equivalent of 1.7 earths worth of resources. That means it takes 18 months for the planet to regenerate 12 months worth of resources. This situation is untenable.

And the challenges to population control are staggering. Most industrialized nations like the U.S. balk at the idea of implementing population controls. But allowing numbers to grow will only meet an inevitable confrontation with fewer resources. Without addressing overpopulation, climate change will continue. And with it, we will see an increase in migration, war, displacement, crime, poverty, disease, and shorter life expectancy.

Climate Warming is Changing Our Oceans

Oceans are big regulators of the planet’s temperature. They absorb and trap heat from the atmosphere — acting like a giant sponge that protects the planet from overheating. The oceans’ layers heat at different rates, with the top layer being the warmest. But over the last 50 years, climate change has increased the temperature of our oceans by 0.3°F. And the ocean’s top layer is now warming at a rate of .2°F per decade.

But what happens when our oceans get too warm? Well, quite a bit. For one, warming oceans increase the rate of melting glaciers and ice sheets. The runoff contributes to rising sea levels, which is already making the consistent flooding of coastal cities and towns a new normal for residents. Less habitable coastal land will bring massive property losses and increased migration by displaced people.

Warming oceans also threaten critical ecosystems like coral reefs, which provide habitats for millions of the world’s aquatic life. The Great Barrier Reef of Australia is already seeing massive “bleaching” effects from warming oceans. And experts predict coral reefs may become all but extinct by 2050 if current trends continue.

Another climate change threat to our planet’s oceans is from increased “acidification” — the rise in acidity from dissolved carbon dioxide. Like heat, oceans also absorb CO2 from our atmosphere and produce half of the oxygen we breathe. Since the Industrial Revolution, increased CO2 emissions have raised the levels of ocean acidification by 30%. Higher acid levels affect calcified shellfish like clams, oysters, and corals by eating away at their protective layers. Any threat to these aquatic species could destroy the entire ecosystem — a system that supplies 15% of the protein intake for 4.3 billion people.

Climate Change is Affecting Your Health

Climate change brings an increase in the severity and frequency of climate events. More flooding, stronger hurricanes, longer heat waves, and rising pollution are a few consequences of a warming planet. These heightened weather phenomena also raise the risks to public health in the following ways:

Less freshwater supplies

A warmer climate means melting glaciers. The roughly 150,000 glaciers around the world store about three-quarters of our freshwater supply. As more glaciers near the earth’s poles retreat, their abundance of fresh water runs into the oceans, becoming undrinkable salt water.

Less freshwater will lead to contaminated water supplies and waterborne diseases like cholera and dysentery (already responsible for 3.4 million deaths each year). Rising sea levels will cause sewage backups and water contamination for coastal cities, exacerbating the situation.

A rise in disease-carrying insects

While warming climates will devastate some species like polar bears, it will be a boon for others like mosquitoes, ticks, and crop pests. Stagnant water and growing populations of insects will spread more mosquito-borne illnesses like malaria and the Zika virus. And more insects means hardier diseases that mutate to become resistant to treatment.

More drowning deaths

Larger and more frequent flooding events will lead to higher losses of life via drowning. Floods are the leading cause of death among all weather-related disasters that happen in the U.S. Drowning while driving is a big problem, specifically for flash floods. People desperate to make it home or to safety too often take the chance to cross flooded areas in their cars. But it only takes 18 inches of water to lift a vehicle, roll it over, and trap the victims inside. Flash floods will be a hallmark of climate change, as sudden and violent downpours will inundate populated areas near river valleys and coastlines.

There are many things you can do to help combat and adapt to climate change. Take part in recycling campaigns, use public transportation, turn off your electronics when you’re not using them, and eat less meat. But one of the most effective things you can do is share what you know. Find reputable information and spread the word to your family, friends, and anyone who will listen.

Renewable Energy in Refugee Camps

dabaab-refugee-campAccess to clean and affordable energy is a prerequisite for sustainable development of mankind, and refugees are no exception. Refugee camps across the world house more than 65 million people, and almost all refugee camps are plagued by fuel poverty. Needless to say, urgent measure are required to make camps livable and sustainable.

Rapid advancements in renewable energy technologies have made it possible to deploy such systems on various scales.  The scalability potential of renewable energy systems makes them well-suited for refugee camps, especially in conflict-afflicted areas of the Middle East, Asia and Africa.

Renewable energy in refugee camps can be made available in the form of solar energy, biomass energy and wind energy. Solar panels, solar cooking units, solar lanterns, biomass cookstoves and biogas plants are some of the popular renewable energy technologies that can improve living standards in refugee camps. It is important to focus on specific needs of refugees and customization of technology towards local conditions. For example, solar technologies are better understood than biogas systems in Jordan.

Solar Energy

Solar energy can provide long-term resilience to people living in refugee camps. With many camps effectively transformed into full-fledged towns and cities, it is essential to harness the power of sun to run these camps smoothly. Solar cookers, solar lanterns and solar water heaters are already being used in several refugee camps, and focus has now shifted to grid-connected solar power projects.

The 5MW Azraq solar project is the world’s first grid-connected renewable energy project to be established in a refugee camp. The project is being funded entirely by Ikea through the Brighter Lives for Refugees campaign. The program, now in its third year, seeks to improve the lives of refugees around the world by providing access to sustainable energy supplies.

Biomass Energy

Due to lack of land and resources, refugee camps puts tremendous pressure on natural vegetation, especially supply of fuel wood to camp-dwellers. Replacement of traditional stoves with efficient biomass-fired cook stoves can save as much as 80% of cooking fuel.

Instead of wood, it would be also be a good option to use agricultural wastes, like husk and straw. Another interesting proposition for refugee camps is to set up small-scale DIY biogas plants, based on human wastes and food residuals. The biogas produced can be used as a cooking medium as well as for power/heat generation.

Wind Energy

Small wind turbines can also play a key role in providing energy to dwellers of refugee camps. Such turbines are used for micro-generation and can provide power from 1kW to 300kW. Majority of small wind turbines are traditional horizontal axis wind turbines but vertical axis wind turbines are a growing type of wind turbine in the small wind market. Small wind turbines are usually mounted on a tower to raise them above any nearby obstacles, and can sited in refugee camps experiencing wind speeds of 4m/s or more.

Conclusions

Renewable energy systems have the potential to improve living standards in refugee camps and ease the sufferings of displaced and impoverished communities. Solar panels, biogas system, biomass stoves and micro wind turbines are some of the renewable energy systems that can be customized for refugee camps and transform them into a less harsh place for displaced people.

Waste Management Challenges in Developing Nations

Waste is the result of collective failure from public, legislative rules, lack of funds and technical support. Public awareness and proper knowledge of waste management and end use of different types of waste, health effects, environmental problems and economic issues that are related to waste management is very important for successful execution of any waste management related practices. Everyone needs to get better knowledge, proper understanding of waste management issues and their practices to curb it. Basic training needs to be initiated from governments in this regard, which can be very effective. Poor knowledge can make the best planned technique questionable.

The increasing cost of waste disposal is a cause of major concern in developing nations

In developing countries, participation level of most citizens in waste management is very low, with residents in urban areas are not actively involved in the process of waste management. Even though it’s low, but very beneficial for future prospect and for more meaningful involvement of majority of public in waste management practices.

People should be educated about sorting out waste based on their type e.g. recyclable waste, hazardous waste, green waste etc. Majority of people across the world are not aware of waste as recycling material, amazingly most of them think plastic is recyclable waste. Involving people who are unaware of waste management practice is extremely difficult.

In developing countries, practices of waste management are usually carried by poor, for their survival. It has been estimated that 2% of population in Asia, Latin America and Africa are dependent on waste for their livelihood. Family organized, or individual manual scavengers are often involved with waste management practices with very limited supportive network and facilities with increased risk of health effects. Also, this practice prevents their children from further education.

Despite the bad consequences, it should be kept in mind that this practice keeps them employed and provide livelihood in countries with high unemployed population. But measure need to be taken to provide their better lifestyles, social behaviour towards people involved in waste management practices, provide them with facilities to reduce their health-related risk and increase their working efficiency.

In developing countries, where government support for waste management is scarce, people need to come strongly against their local municipal office or government if they see things are not changing and stacks of waste are piling up. They should protest to protect their environment, health and keep living secure and healthy for their children.
