- New Study Suggests Melting Arctic Permafrost Poses Big Climate
- Threat
- VOA News
- 21 July 2020
- A new study indicates that the accelerated melting of Arctic
- permafrost could release as much as 40 billion tons of carbon
- into the atmosphere not previously accounted for in global
- emissions estimates.
- Permafrost is the thick layer of soil in the world's Arctic and
- Antarctic regions that, for centuries in some cases, has remained
- frozen throughout the year. It is vital to the world's climate
- because it stores twice as much carbon as there is in the
- atmosphere.
- The study, published Monday in the science journal Nature
- Geoscience, examines how under usual circumstances, the top layer
- of this frozen soil thaws during summer w8hgde tã
- microorganisms spring to life. The microbes eat plant roots and
- respirate like all living organisms and inevitably emit
- greenhouse gases, mostly carbon dioxidEa This process is knrnrhizosphere priming.
- The researchers sa tmore and more of the prior frozen soil
- thawing, more plant roots are exposed to microorganisms, which in
- turn emit more carbon dioxide. The researchers determined the
- phenomenon could add as much as 40 billion tons of carbon to the
- atmosphere by the year 2100.
- Prior to this study, scientists estimated that global emissions
- mu r1xlat 7.6% every year over the next 10 years to meet the
- 1.5°C temperature goal of the Paris Agreement. But the authors of
- the study note that their new estimates of emissions from
- permafrost melting are currently "unaccounted for in global
- emission scenarios and implies that the remaining anthropogenic
- carbon budget to keep warming below 1.5 or 2?°C ... may need to
- be even more constrained."
- While Earth is heating up, warming is significantly worse in the
- Arctic. Analysis from NASA and the U.S. National Oceanic and
- Atmospheric Administration suggest that the past decade was the
- hottest on record overall. In the Arctic, air temperatures are
- rising twice as fast as the global average.
- This new study shows that permafrost melt can, in turn, prompt
- further melt. More carbon in the atmosphere means worsened
- atmospheric warming and more melting.

- From Deutsche Welle:
- Farming in the desert: Are vertical farms the solution to saving
- water?
- 22 July 2020
- Isabelluelsen
- With high temperaturo drd water scarcity, the Emirates
- might seem an unlikely place for a farm. Yet as coronavirus
- and climate change heighten the desire for food security,
- could vertical farms be the solution?
- "When I told people I was going to grow tomatoes in the desert,
- they qMì¾as craza," Scarvest
- Smart Farms, told DW.
- With just an average 12 days of rain a year, less than 1% arable
- land, a desert location and an 80% import rate for food, the
- United Arab Emirates (UAE) seems an unfa w3nS Ee one of several entrepreneurs using high-tech
- farming
- techniques to bheleaehl
- built the first climate-controlled greenhouse in Abu Dhabi in
- 2017.
- Prompted by arid conditions and a desire for greater food
- security, the country is investing millions in technologies —
- such as vertical farming — that could make it an unlikely
- agricultural pioneer.
- Vertical farms can grow a rich variety of different crops by
- stacking them in layers under LED lighting in climate-controlled
- greenhouses and watering them with mist or drip systems. The
- process is tailored to each crop's specific needs, resulting in
- high-yield, year-round harvests.
- "It takes 30 to 40 days to grow leafy greens out in the field. We
- can grow that exact same crop in 10 to 12 days," says Marc
- Oshima, co-founder of Aerofarms. The company received funding
- from the Abu Dhabi Investment Office to build the capital's
- largest indoor vertical farm, with 800 different crops, by 2021.
- Water scarcity and fossil-fuel reliance
- The technology uses minimal land and up to 95% less water than
- conventional agriculture.
- The hydroponics system places the plants' roots directly into a
- water-based and nutrient-rich solution instead of soil. This
- "closed loop" system captures and recirculates all the water,
- rather than allowing it to drain away — useful for a country like
- the UAE suffering from extremely high water stress.
- Globally, agriculture accounts for 70% of freshwater withdrawals,
- and UAE is extracting groundwater faster than it can be
- replenished, according to the International Center for Biosaline
- Agriculture (ICBA).
- "Water is very expensive over in the UAE, but energy is cheap as
- it is subsidized," says Jan Westra, a strategic business
- developer at Pr, a company providing technology to vertical
- farms.
- The artificially controlled environment is energy intensive
- because the air conditioning and LED lights need a constant
- source of electricity.
- This is bringing forth life in the desert could come at a high
- environmental cost. Most of that energy comes from
- carbon-emitting fossil fuels, even as the Middle Eastern country
- feel the effects of climate change.
- By 2050 Abu Dhabi's average temperature is predicted to increase
- by around 2.5°C in a business-as-usual scenario. Over the next
- 70 years patterns of rainfall are also expected to change.
- Integrating renewable energy
- Althoughv·,d \ zest is building a solar-powered farm in
- neighboring Saudi Arabia, its UAE operations get electricity from
- the carbon-intensive national grid.
- Investing more in renewables "is a goal of ours," Kurtz told DW.
- He said the company has not set a clean energy target but is
- working on various green power projects, including a plan to
- integrate solar power generated in UAE into its operations.
- However, Willem van der Schans, a researcher specializing in
- short supply chains at Wageningen University in the Netherlands,
- says sustainability and clean energy should be "inherent in the
- technology and included in plans when starting a vertical farm."
- He argues that many vertical farming companies are not
- sustainable in terms of energy as they still view clean power as
- an optional "add-on."
- smahane Elouafi, director general of the government funded ICBA
- in Abu Dhabi, acknowledges that vertical farming has some way to
- go before acitsving "real sustainability," but she believes the
- innovations are "promising."
- Improved battery storage, increasingly efficient LED lights and
- cheaper solar panels will help, she adds.
- Local solutions
- By 2050, the UAE government wants to generate almost half its
- energy from renewable sources.
- Fred Ruijgt, a vertical farming specialist at Priva, argues that
- it's important to factor transport and refrigeration into the
- energy equation. Vertical farming uses more energy to grow crops
- than tradpnH e Ni ,locally, they do not havok ï ïhPr ed by air, sea or truck
- over long distances.
- "The energy saving is difficult to calculate exactly, but the
- advantages of locally grown crops are huge," he says, adding that
- those grown in vertical farms not only use less water and
- pesticides, but that they also have a longer shelf life due to
- minimal transportation time.
- Food security and coronavirus
- In 2018, the UAE set out its vision to become a hub for h etEttQ
- local food production.
- Companies and investors have flocked to the region, attracted by
- the 0% corporate tax rate, low labor costs and cheap energy. With
- their help, UAE aims to reduce its reliance on imports and make
- its foÉlf iobhocks like climate change and
- pandemics.
- Oshima from Aerofarms says the coronavirus pandemic has brought
- "greater appreciation of how fragile the supply chain is and
- raised questions about food safety and security."
- When the UAE went into lockdown in April, imported supplies of
- perishable goods like vegetables fell and business boomed for
- local suppliers.
- ICBA's Elouafi said they have helped keep the UAE well-stocked
- during the pandemic.
- "With the help of local food production and adequate imports,
- there has been absolutely no shortage of food in the UAE,"
- Elouafi told DW.
- Climate change, however, poses an altogether more complex threat
- to the country in the long-term. Given climate change's likely
- impact on food production, she says vertical farming has shown it
- is "an economically viable proposition even with harsh climatic
- conditions."
