Land Degradation: Meaning, Causes and Prevention of Land Degradation

b471

The change in the characteristic and quality of soil which adversely affect its fertility is called as Degradation.

Land degradation means:

1. Loss of natural fertility of soil because of loss of nutrients

2. Less vegetation cover

3. Changes in the characteristic of soil

4. Pollution of water resources from the contamination of soil through which water sweeps into ground or runoff to the water bodies

5. Changes in climatic conditions because of unbalanced created in the environment

Finished Projects by Arid Zone Afforestation

tree0001

Arid Zone Afforestation (AZA) is a non-profit organization that acts to combat desertification on a local and global level, in arid, semi-arid, and deserted regions, where rainfall is limited or non-existent, by the use of innovative, environmentally friendly planting technologies, such as the Safe Tree planting system.

Our mission is to make the world green. So, visit our website to learn more about us. Let’s all fight for a better future!!

Scientists just accidentally discovered a process that turns CO2 directly into ethanol

pollution-smoke_1024

If scientists can figure out how to convert atmospheric carbon dioxide into fuel, and do it at an industrial scale – it would, quite literally, change the world. Last month, we hit the highest levels of atmospheric CO2 in 4 million years, and it’s now permanent, meaning we’ll never be able to drop to ‘safe’ levels again.

But if we can turn CO2 into a fuel source, we can at least slow things down a bit, and now researchers have developed a process that can achieve this with a single catalyst.

High court rules UK government plans to tackle air pollution are illegal

3903

Court rules for second time in 18 months that the government is not doing enough to combat the national air pollution crisis. The government’s plan for tackling the UK’s air pollution crisis has been judged illegally poor at the high court, marking the second time in 18 months that ministers have lost in court on the issue.

The defeat is a humiliation for ministers who by law must cut the illegal levels of nitrogen dioxide suffered by dozens of towns and cities in the “shortest possible time”.

How urban trees can save lives?

tree0003

Heatwaves are one of the world’s most underestimated threats, killing more than 12,000 people every year around the world, more than any other weather-related event. And heat is especially dangerous in cities, which tend to be much warmer than surrounding less-developed areas. On top of that, cities tend to have higher levels of air pollution, which contribute to more than 3 million deaths every year. With 70 percent of the world’s population predicted to live in cities by 2050, heat and air pollution constitute a major public health concern.

One relatively simple solution to this problem? Plant more trees in cities. Trees cool the air by casting shade and releasing water vapor, and their leaves can filter out fine particulate matter (PM)—one of the most dangerous forms of air pollution, generated from burning biomass and fossil fuels.

So, take action by planting a tree. It is so simple, but very important.

We just entered an alarming ‘new era’ of global warming

https-_blueprint-api-production-s3-amazonaws-com_uploads_card_image_257747_co2_wearehere

The Earth permanently passed a global warming threshold last year that alarms climate scientists and has profound consequences for everyone alive today, particularly young people looking forward to the future.

According to the World Meteorological Organization (WMO), observatories around the world found that in 2015 and 2016, the amount of carbon dioxide in the atmosphere crossed the symbolic threshold of 400 parts per million (ppm), and that this is likely to remain the case for the foreseeable future.

This is the highest level ever seen in all of human history and is 144 percent higher than the pre-industrial average. Such a high level is also very likely the highest on record going back to between 800,000 and 15 million years ago, based on various studies.

Antarctica’s Ice Sheets Are Melting Faster And From Beneath

antarctic_custom-c054aaacc042163d09a0694b26f5822e4a35714c-s800-c85

Antarctica’s ice has been melting, most likely because of a warming climate. Now, newly published research shows the rate of melting appears to be accelerating.

Antarctica is bigger than the U.S. and Mexico combined, and it’s covered in deep ice, more than a mile deep in some places. Most of the ice sits on bedrock, but it slowly flows off the continent’s edges. Along the western edge, giant glaciers creep down toward the sea. Where they meet the ocean, they form ice shelves.

We are talking about a very important problem, for which, however, many people are unaware. Learn more about it and take action:

Turbo fuel to fight climate change?

15840379_403

American scientists have stumbled upon a cheap and easy way to convert CO2 into ethanol. Yes, the stuff that can also be used to fuel your car.

“We discovered somewhat by accident that this material worked,” says Adam Rondinone. Together with his colleagues, the scientist made a discovery that could put the greenhouse gas carbon dioxide to good use. What the scientists did, in principle, is reverse the combustion process that produces carbon dioxide. The end product of the experiment at the US Department of Energy’s Oak Ridge National Laboratory they produced ethanol. And this fuel, in turn, could not only power cars but also help to store energy.

Young Greens Welcome Clean Air Ruling

bg

The Young Greens of England and Wales welcomes the ruling that Theresa May’s government is not taking action on air pollution.  Toxic air is one of the greatest environmental threats to young people in the UK.  Not only will the youth of today pay the price for climate change partly caused by pollution, but suffer the consequences of air pollution every day.

An estimated 40,000 premature deaths each year are caused by air pollution.  Additionally, air pollution is one of the main triggers of breathing disorders such as asthma.  A study found that two-thirds of people found traffic fumes to make their asthma worse, and a shocking 42% of asthma suffers actively avoid areas of high traffic to protect their health. A study has even shown that air pollution impacts our mental health.

Wealthy countries doing ‘nowhere near enough’ to help poorest cope with climate change

somalilanddrough

Wealthy nations are doing “nowhere near enough” to help the world’s poorest people cope with the effects of climate change. As part of the Paris Agreement of Climate Change, rich states promised to raise $100bn (about £81bn) a year by 2020 to help the poorest ones, either by providing money directly or persuading private companies to contribute. However, instead of giving money, most countries were lending it, while others were rebranding ordinary aid as climate finance.
