China's Plan To Cut Meat Consumption By 50% Cheered By Climate Campaigners

The Chinese government has outlined a plan to reduce its citizens' meat consumption by 50%, in a move that climate campaigners hope will provide major heft in the effort to avoid runaway global warming.
New dietary guidelines drawn up by China's health ministry recommend that the nation's 1.3 billion population should consume between 40g to 75g of meat per person each day. The measures, released once every 10 years, are designed to improve public health but could also provide a significant cut to greenhouse gas emissions.
The Chinese Communist party has found unusual allies among Hollywood celebrities, with actor Arnold Schwarzenegger and director James Cameron involved in a series of new public information adverts encouraging Chinese people to consume less animal flesh to help the environment.
Should the new guidelines be followed, carbon dioxide equivalent emissions from China's livestock industry would be reduced by 1bn tonnes by 2030, from a projected 1.8bn tonnes in that year.
Globally, 14.5% of planet-warming emissions emanate from the keeping and eating of cows, chickens, pigs and other animals – more than the emissions from the entire transport sector. Livestock emit methane, a highly potent greenhouse gas, while land clearing and fertilizers release large quantities of carbon.
"Through this kind of lifestyle change, it is expected that the livestock industry will transform and carbon emissions will be reduced," said Li Junfeng, director general of China's National Center on Climate Change Strategy and International Cooperation.
"Tackling climate change involves scientific judgement, political decisions, entrepreneurial support, but at last, it still relies on involvement of the general public to change the consumption behavior in China. Every single one of us has to believe in the low-carbon concept and slowly adapt to it."
Meat has gone from rare treat to a regular staple for many Chinese people. In 1982, the average Chinese person ate just 13kg of meat a year and beef was nicknamed "millionaire's meat" due to its scarcity.
The emergence of China as a global economic power has radically altered the diets of a newly wealthy population. The average Chinese person now eats 63kg of meat a year, with a further 30kg of meat per person expected to be added by 2030 if nothing is done to disrupt this trend. The new guidelines would reduce this to 14kg to 27kg a year.
China now consumes 28% of the world's meat, including half of its pork. However, China still lags behind more than a dozen other countries in per capita meat consumption, with the average American or Australian consuming twice as much meat per person compared to China.
According to a new report by WildAid, the predicted increase in China's meat consumption would add an extra 233m tonnes of greenhouse gases to the atmosphere each year, as well as put increased strain on the country's water supply, which is already blighted by polluted and denuded rivers and groundwater.
The report warns that unchecked Chinese meat consumption will also degrade its arable land and worsen the country's problems with obesity and diabetes. An estimated 100 million Chinese people have diabetes, more than any other country.
Research released by the thinktank Chatham House in 2014 forecast that China alone is expected to eat 20m tonnes more of meat and dairy a year by 2020 and warned that "dietary change is essential" if global warming is to not exceed the 2C limit eventually imposed at the climate accord in Paris last year.
A separate report by scientists at the Oxford Martin School this year found that the widespread adoption of vegetarianism around the world could bring down greenhouse gas emissions by nearly two-thirds.
"China's move to cut meat consumption in half would not only have a huge impact on public health, it is a massive leadership step towards drastically reducing carbon emissions and reaching the goals set out in the Paris agreement," said James Cameron.
"Animal agriculture emits more than all transportation combined. Reducing demand for animal-based foods is essential if we are to limit global warming to 2C as agreed at COP21."

New Crop Varieties 'Can't Keep Up With Global Warming'

Crops yields around the world could fall within a decade unless action is taken to speed up the introduction of new varieties.
A study says temperatures are rising faster than the development of crop varieties that can cope with a warmer world.
In Africa, researchers found that it can take 10-30 years before farmers can grow a new breed of maize.
By the time these new crops are planted, they face a warmer environment than they were developed in.
The scientists behind the study, published in the journal Nature Climate Change, looked closely at the impact of temperature rises on crop duration - that's the length of time between planting and harvesting.
They found that in a warmer world durations will be shorter meaning these varieties will have less time to accumulate biomass and yields could be affected.

Out of date
In their paper, the researchers write that crop duration will become significantly shorter as early as 2018 in some regions but by 2031, the majority of maize-growing areas of Africa will be affected.
"The actual changes in yield may be different but this effect is there, the impact of this change in duration will occur unless breeding changes," said lead author Prof Andy Challinor from the University of Leeds.
"The durations will be shorter than what they were bred for - by the time they are in the field they are, in terms of temperature, out of date."
New varieties of maize need between 10-30 years of development before they are ready to be grown by farmers.
The scientists say the lag is down to a combination of factors including the limited number of crops you can grow in a season, the need for government approved testing and there are also a number of problems of access to markets that can increase the time it takes before the farmers have the new seeds to plant.
Increasing the speed of development is important but according to Prof Challinor, so is making smarter assumptions about future conditions.

"We can use the climate models to tell us what the temperatures are going to be," he told BBC News,
"We can then put those temperature elevations into the greenhouses and then we can breed the crops at those temperatures. People are beginning to do this, but this paper provides the hard evidence of the necessity of it."
Researchers are also working on the impact of heat stress on crops at sites in Zimbabwe, Kenya and Ethiopia. Data from these trials is being used to identify species that could cope with warmer conditions.
But would the use of genetic modification (GM) help speed up this type of work?
"GM does some things faster, so you would get a new variety of crop faster," said Prof Challinor.
"But it doesn't get you out of the testing requirement in fact the testing may in fact be greater and it doesn't help it all with farmers accessing seeds and markets - the problem will remain even for a magic GM crop."
Better techniques and more money for research are the keys according to others in this field, familiar with the study.
"Investment in agricultural research to develop and disseminate new seed technologies is one of the best investments we can make for climate adaptation," said Dr Andy Jarvis, from the International Centre for Tropical Agriculture,
"Climate funds could be used to help the world's farmers stay several steps ahead of climate change, with major benefits for global food security."
The researchers believe that the study also has implications beyond Africa, especially in the maize growing regions of the tropics.

Climate Change To Affect How And Where Fruit Is Grown

Fairfax

Red apples could be a bit less red as temperatures rise due to climate change, Royal Galas are likely to suffer more sun damage, and some fruit growers are likely to rip out trees and opt for different varieties.
The looming impact of climate change on the fruit growing industry is detailed in a new report out of the University of Melbourne, which says climate change could affect what is grown and where in some Australian apple growing regions.
The report concentrates on science, but as climate change affects farmers and the fruit that they grow, a changing climate is likely to have some impact on the apples displayed on the shelves of Australian supermarkets in future years.
Northern Victoria's Goulburn Valley, one of the biggest apple-growing districts in Australia, faces a real threat from a rise in the number of hot days in January that could lead to "sun damage" on Royal Gala apples, the report warns.

Royal Gala is a popular variety picked from about January onwards in the Goulburn Valley. Its maturity and the early weeks of harvest coincide with the hottest weather of the Victorian summer, which comes in February and January.
The report author Rebecca Darbyshire said Goulburn Valley growers got a blast of hot weather in early 2009 that illustrated the severe potential consequences of sun damage.
"(For) early season varieties it is a significant risk and they've already experienced it, this is happening. Some of the growers lost huge amounts of their crop, somewhere between 30 and 70 per cent," she said.
"What we found is that that risk of damage is likely to definitely increase into the future. By 2030 on average about nine days in January will be crossing the threshold for damage for Royal Gala, that's nearly a third of the whole month," she said.
But Dr Darbyshire said strategies could be implemented to address the threat posed by higher temperatures, such as netting and "overhead sprinklers" to cool the apples.

The report said that growing regions in WA and one in south-east Queensland could face warmer winters beyond 2030 that would not deliver the chill needed for growing Golden Delicious apples.
But the researchers said other regions where Golden Delicious is grown such as the Yarra Valley east of Melbourne, Batlow in New South Wales and Huonville in Tasmania "face little risk and cropping of Golden Delicious is not expected to be limited in relation to winter chill".

Dr Darbyshire and fellow researcher Sigfredo Fuentes also investigated the possible impact of climate change on flowering times for Pink Lady apples (also known as Cripps Pink apple).

The investigators found that "flowering will likely be delayed as climate change progresses".
"This means that flowering will occur in warmer temperatures which may have positive (increased final yields) and negative (lower firmness values and greater yellow background colour) impacts on production."

Climate Change: Poll Finds Support For Strong Action At Highest Level Since 2008

Support for strong action on climate change is at its highest level since 2008, with much sought after uncommitted voters showing the strongest support, according to Galaxy polling commissioned by the Climate Institute.
Despite that, voters were dissatisfied with both Labor and Coalition policies, with only 17% saying the Coalition had a credible climate plan and only 20% saying Labor did.
Those findings fitted with an assessment of the main parties' policies conducted by the Climate Institute, which concluded the Coalition plan was "currently inadequate" and Labor's merely had "pathways to credibility".
They found the Greens' and Glenn Lazarus Team's policies on climate change were the strongest and most credible.
Concern about climate change rose significantly since the last federal election, from 53% in 2013 to 72% in 2016.
Concern among Coalition voters jumped the most, from 41% in 2013 to 62% now.
But uncommitted voters were the most likely to be concerned about climate change, with 76% of them either "fairly" or "very" concerned, according to the national polling of 1,100 people.
Almost two-thirds of respondents agreed Australia should be a world leader in finding solutions to climate change, up from 52% in 2012.
Only 23% thought Australia should wait for other countries before strengthening its post-2020 emissions targets.
And 60% of voters thought delaying action would cause shocks to jobs and energy supplies.
The Climate Institute also assessed what they described as the "credibility" of the parties contesting government or they thought were likely to be re-elected to the Senate.
Each of the six parties was assessed on the basis of their 2030 emissions reduction targets and their timeframe for achieving net zero emissions.
The Climate Institute also looked at the implications for global warming if all countries matched that party's targets and how Australia would rank on per capita emissions among the G20 if that party's policies were adopted.
The Greens and the Glenn Lazarus Team came out as being ranked equally among G20 nations, with their policies putting Australia eighth among G20 nations and causing a temperature rise of between 1.5C and 2C.
The Coalition was at the bottom of parties that had a climate policy, putting Australia at 18th spot among G20 nations and resulting in temperature rises of between 3C and 4C.
Labor performed better but wasn't consistent with keeping warming under 2C and left Australia at 15th among G20 nations.
The Nick Xenophon Team came out in the middle, doing better than Labor but not as well as the Greens.
The Jacqui Lambie Network was the worst, unable to be properly assessed since they don't have any targets.
John Connor, the chief executive of the Climate Institute, said the polling and assessments showed there was a clear opportunity for government develop constructive climate change and energy policies.
"Our research shows that all our political parties need to do more to develop policies that not only build credibility but also build community and investor confidence," he said.
"This is a critical finding, given that both major parties are promising key reviews next year amid greater domestic and international scrutiny."
The Climate Institute called for three policy steps:
Pre 2050 net zero emission objectives, with credible emission reduction pathways and regular independent processes of review.
Economic and community strategies to manage the transition to decarbonisation.
Integration of climate risks and opportunity assessments into core decision making.
"After 10 turbulent years, Australian business and the voting public have tapped into international trends about the economic and environmental benefits of climate action," Connor said.
"Our main political parties urgently need to catch up."
