What thrives in poor soil, can tolerate rising temperatures and is brimming with calories?
The cassava – sometimes referred to as "the Rambo root." This plant could potentially help alleviate world hunger, provide economically viable agriculture and even put an end to soil erosion, according to research published in the journal Conservation Science and Practice.
Also known as yuca (but distinct from the ornamental yucca plant) the root of the cassava is a staple of many Caribbean and South American meals – and it will thrive in conditions too difficult for many other plants.
A Gateway Crop
"Evidence suggests (cassava) could potentially revive degraded land and make it productive anew, generating numerous positive socioeconomic and environmental impacts with proper crop management," said Maria Eliza Villarino, the report's lead author and a researcher at the Alliance of Bioversity International and the International Centre for Tropical Agriculture (CIAT), in the science publication, PhysOrg.
An estimated 40% of land in Colombia suffers from degradation, according to the alliance. It, therefore, "serves as a good testing ground for exploring the different possibilities that farming cassava could lead to."
The cassava could become a gateway crop, helping farmers bring once unproductive land back into use. Soil that has been revived could then be used to grow commercial crops like coffee or chocolate, corn or soy.
But Cassava Mustn't Tread the Same Path as Soy
The global market for soy is estimated at around $150 billion, and around 80% of all soy production comes from the U.S., Brazil and Argentina. Making space for soy farms has resulted in significant deforestation in parts of the Amazon rainforest, with the WWF estimating that "an area roughly the size of California" was lost to deforestation around the world between 2004 and 2017.
"We acknowledge that scaling up production of any commodity risks an increase in deforestation and biodiversity loss, and we need to do more research," Augusto Castro Nunez, a land-use and climate specialist at the alliance, said in the PhysOrg article. "But what we know is that we need something new; what has been done to prevent deforestation is not working, and this is something new."

'Regenerative Agriculture and the Soil Carbon Solution': New Paper Outlines Vision for Climate Action
By Andrea Germanos
A white paper out Friday declares that "there is hope right beneath our feet" to address the climate crisis as it touts regenerative agriculture as a "win-win-win" solution to tackling runaway carbon emissions.
Graph from Rodale Institute's new white paper "Regenerative Agriculture and the Soil Carbon Solution."<p>The claim made in the new paper is bold: "Data from farming and grazing studies show the power of exemplary regenerative systems that, if achieved globally, would drawdown more than 100% of current annual CO2 emissions.</p><p>"Regenerative agriculture, as the researchers describe, represents "a system of farming principles that rehabilitates the entire ecosystem and enhances natural resources, rather than depleting them."</p><p>In contrast to industrial practices dependent upon monocultures, extensive tillage, pesticides, and synthetic fertilizers, a regenerative approach uses, at minimum, seven practices which aim to boost biodiversity both above and underground and make possible carbon sequestration in soil.</p><ul><li>Diversifying crop rotations</li><li>Planting cover crops, green manures, and perennials</li><li>Retaining crop residues</li><li>Using natural sources of fertilizer, such as compost</li><li>Employing highly managed grazing and/or integrating crops and livestock</li><li>Reducing tillage frequency and depth</li><li>Eliminating synthetic chemicals</li></ul>
Climate Crisis Could Change Permafrost Soil Microbes, With ‘Unknown Consequences’ for Arctic Ecosystems, Scientists Say
Can the past predict the future?
In the case of communities of microbes living in the Arctic permafrost, researchers at the University of Alberta think it might. The scientists discovered that the microbes and chemistry of Arctic soil changed dramatically following the end of the last Ice Age, and the same thing could happen again due to the climate crisis.

From raising livestock to growing vegetables, farmers help put food on our plates. But agriculture also creates emissions that warm the climate. And the most warming is caused by nitrous oxide, an especially potent global warming gas.

"Forests are the lungs of our land, purifying the air and giving fresh strength to our people," said former U.S. president, Franklin Roosevelt.
So the FAO is using Twitter to remind the world of these five hidden benefits of forests.
One of the concerns about a warming planet is the feedback loop that will emerge. That is, as the planet warms, it will melt permafrost, which will release trapped carbon and lead to more warming and more melting. Now, a new study has shown that the feedback loop won't only happen in the nether regions of the north and south, but in the tropics as well, according to a new paper in Nature.

Farmers are the stewards of our planet's precious soil, one of the least understood and untapped defenses against climate change. Because of its massive potential to store carbon and foundational role in growing our food supply, soil makes farming a solution for both climate change and food security.

Lebanese Prime Minister Hassan Diab says he believes Tuesday's explosion in Beirut could have been caused by large quantities of ammonium nitrate stored in the port.
What Is Ammonium Nitrate?<p>Ammonium nitrate is a white crystalline salt that can be fairly cheaply produced from ammonia and nitric acid. It is soluble and often used as fertilizer, as nitrogen is needed for healthy plant development.</p><p>Ammonium nitrate in its pure form is not dangerous. It is, however, heat sensitive. At 32.2 degrees Celsius (89.96 degrees Fahrenheit), ammonium nitrate changes its atomic structure, which in turn changes its chemical properties.</p><p>When large quantities of ammonium nitrate are stored in one place, heat is generated. If the amount is sufficiently vast, it can cause the chemical to ignite. Once a temperature of 170 C is reached, ammonium nitrate starts breaking down, emitting nitrous oxide, better known as laughing gas. Any sudden ignition causes ammonium nitrate to decompose directly into water, nitrogen and oxygen, which explains the enormous explosive power of the salt.</p>
Deadly Disasters<p>As ammonium nitrate is a highly explosive chemical, many countries strictly regulate its use. Over the past 100 years, there have been several disasters involving the chemical.</p><p>In 1921, for example, a massive blast occurred at a BASF chemical plant in Ludwigshafen in the German state of Rhineland-Palatinate. About 400 metric tons of a mixture of ammonium sulfate and ammonium nitrate exploded, killing 559 people and injuring 1,977. The plant was largely destroyed in the blast, which could be heard as far away as Munich, some 300 kilometers (186 miles) distant.</p><p>In 2015, explosions caused by ammonium nitrate ripped through the <a href="https://www.dw.com/en/china-convicts-dozens-for-last-years-giant-explosions-in-tianjin/a-36324321" target="_blank">Chinese port city of Tianjin</a>. Eight hundred metric tons of the chemical were said to have been stored along with other substances in a warehouse for hazardous materials. The blasts killed 173 people and destroyed an entire city district.</p><p>Two years earlier, in 2013, an ammonium nitrate explosion occurred at the West Fertilizer Company site in Texas, killing 14 people. And in 2001, 31 people died in Toulouse, France, in an explosion caused by the chemical.</p>
Terrorist Favorite<p>In Germany, the purchase and use of ammonium nitrate is regulated by the explosives act. This is because the cheap, highly explosive and relatively easily obtainable material has in the past been used by terrorists to carry out attacks.</p><p>For example, in 1995, U.S. conspiracy theorist and gun enthusiast Timothy McVeigh used a mixture of ammonium nitrate and other substances to bomb the Alfred P. Murrah Federal Building in Oklahoma City. Norwegian far-right extremist Anders Behring Breivik also used ammonium nitrate in a car bomb attack in Oslo in 2011.</p>
