    Summary:
    Changing agricultural practices and ending food waste around the world are among recommendations made by scientists charged with looking at ways to mitigate global climate change. “Agriculture globally contributes about 10 to 12 percent to greenhouse gas emissions,” the author said. “If you add in forestry it moves it up to around 25 percent. Agriculture is significant but not the major contributor and has declined slightly, percentage-wise, since the last report in 2007, not so much because agriculture has changed that much but because the energy sector is contributing more.”

    The latest assessment of global climate change is out and scientists from around the world have recommended changes including some in agriculture, forestry and other land use designed to mitigate their effects on climate change.

    As a lead author of a chapter in the Intergovernmental Panel on Climate Change assessment report released this month, Kansas State University Distinguished Professor and soil microbiologist Chuck Rice gave a presentation at the World Bank on April 16. Rice was part of a group of 18 authors from around the world who wrote the chapter pertaining to agriculture, forestry, and other land use. In an interview, he discussed some of the recommendations made by the authors.

    Most greenhouse gases come from burning fossil fuels to produce energy, although deforestation, industrial processes, and some agricultural practices also emit gases into the atmosphere, according to the Environmental Protection Agency. Greenhouse gases act like a blanket around Earth, trapping energy in the atmosphere and causing it to warm. This is called the greenhouse effect and is natural and necessary to support life on Earth. However, a buildup of greenhouse gases can change Earth’s climate.

    “Agriculture globally contributes about 10 to 12 percent to greenhouse gas emissions,” Rice said. “If you add in forestry it moves it up to around 25 percent. Agriculture is significant but not the major contributor and has declined slightly, percentage-wise, since the last report in 2007, not so much because agriculture has changed that much but because the energy sector is contributing more.”

    IPCC Assessment Reports Background

    “The IPCC was started in the late 1980s when the first President Bush signed with other countries that climate change was an issue for the planet,” said Rice, who added that this latest report is one of a series that has come out every seven years. “Our chapter addresses agriculture’s role in the future of the emission of greenhouse gases.”

    This is the fifth assessment report, said Rice, who also served on the fourth report which received the Nobel Peace Prize. Overall, the panel includes three working groups — one studying the science involved in climate change, one studying the adaptation to climate change and one studying the mitigation of climate change which is the group Rice’s team is part of. About 240 scientists, including specialists in forestry, land use, social science, economics and others, contributed to the third group report’s 16 chapters.

    “It’s important to remember that we’re not creating new science but rather assessing the current state of the science on how agriculture, forestry and land use contribute to and can mitigate greenhouse gas emissions,” Rice said. They conducted literature reviews and summarized key points of the science that’s occurred since the last report in 2007.

    He acknowledged that the words “climate change” can be controversial among some people, but added, “As far as greenhouse gas emissions and concentrations in the atmosphere, I don’t think there’s any controversy. Those are true measurements. The science is really solid on that. What people might question is, what’s the impact of those greenhouse gases?”

    “It is certainly clear by 97 percent of those climate scientists that the increases in greenhouse gases such as CO2, nitrous oxide and methane, have resulted in about a 1.5 degree Fahrenheit increase in global temperatures. That’s an important point, that it’s global,” he said. “There’s a lot of variation around the globe. In time our atmosphere goes through natural cycles and what the scientists are saying is that what we’re doing is enhancing those cycles.”

    Rice said that even the cold weather in the United States this past winter might make sense in relation to climate change because the rest of the globe was warmer. Because of that, weather patterns in the Arctic Circle were affected which impacted the U.S.

    Key Recommendations for Agriculture, Forestry and Other Land Use

    Soil carbon sequestration — One of the recommendations coming out of this and previous reports is that carbon be sequestered through land management changes, Rice said of practices that hold carbon in the soil. Through reduced tillage in farming — no-till being the prime example — and systems using cover crops and residue, those are major ways agriculture can reduce the emission of greenhouse gases because carbon dioxide is being taken up by the plant materials and stored in the soil.

    “It turns out that (carbon sequestration) has multiple benefits. If you increase the carbon content, you improve the quality of the soil. It makes it more productive, less prone to erosion and the organic matter helps hold water so it provides some adaptation to the droughts and heat we have in Kansas,” Rice said.

    Although the practice of not tilling the soil (no-till) started in the United States, two other countries, Brazil and Argentina, are the world leaders in no-till, said Rice, adding that 80 percent or more of agricultural land in Brazil and Argentina are farmed using no-till systems.

    “In the U.S., some estimates are 25-30 percent (in no-till) but that’s not continuous no-till,” he said. “We’re probably at about 10 to 15 percent continuous no-till, so there’s a huge opportunity in the U.S. for our role to manage our own emissions, but there’s also opportunity around the world where no-till has been less well received, to take action in this way.”

    Promoting product use with low emissions — This recommendation pertains mostly to the forestry sector, Rice said. Cement is a major emitter of carbon dioxide (CO2) greenhouse gas, so the authors suggested that wood products or others with lower emissions than cement be considered where cement has traditionally been used.

    In addition, however, agriculture’s use of fossil energy could be reduced as a mitigation step, Rice said: “When we make agriculture more efficient and use less tillage, we’re also using less energy. We can make agriculture more efficient and more profitable in this way because energy is a significant cost. So it has the benefit of reducing emissions, direct and indirect, and therefore increasing profitability.

    “That’s one of the unusual aspects for our sector, is that land is used for multiple things — agriculture, forestry, and ecosystem services, including water quality and wildlife. So this sector has some opportunities to help improve the quality of land resources as well as mitigating climate change.”

    Increasing crop yields and livestock feeding efficiency. Rice described this proposal as reducing inputs while maintaining or increasing outputs, which makes production more efficient.

    For U.S. farmers, he said, nitrogen makes up about 40 percent of their inputs: “That’s not true around the world but we can improve that. In livestock emissions, U.S. and Europe have made strides to make livestock production more efficient but in some other parts of the world, lower quality of animal plus poor forage quality leaves much room for improvement in livestock efficiency.”

    Pursuing changing human diets away from food animal products — Rice acknowledged that this recommendation may be controversial, but the authors determined that changing human diets away from food animal products could help in mitigating greenhouse gasses.

    “Methane emissions from livestock is a major contributor to agriculture’s footprint,” Rice said. “Approximately 40 percent of agriculture’s emissions are due to livestock and if we could reduce livestock that would reduce emissions. The report acknowledges that there are social and political barriers to all of these options. Certainly the consumption of meat would be a social barrier. Traditionally as countries increase their personal income, meat or protein consumption goes up.”

    Because livestock production is a contributor to greenhouse gases, he said, it had to be put on the table.

    Reducing food waste — “Another thing that’s easier to accomplish is cutting back on food waste,” he said, adding that 30 to 40 percent of food that’s produced is not used.

    “Agriculture’s in a unique position,” Rice said. “If you look at the mitigation options in the next 20 to 30 years, if agriculture implemented all of those mitigation practices around the world, it would come close to mitigating all of agriculture’s contributions to greenhouse gasses so it would have a net zero effect, plus a lot of these things would make agriculture more efficient.”

    He said the report will be shared with policy makers who next meet in Paris in 2015. Those individuals will come up with policies for countries to implement aimed at reducing greenhouse gases.

    “Kansas has always had drought, heat trends and cold events. A lot of these mitigation options are things we should be doing anyway — improving soil quality, reducing erosion — so this effort is going to help Kansas agriculture whether you agree that humans are having an effect on climate change,” Rice said. “A lot of the things we’re talking about are things that you should be doing for the environment as well as things that are profitable for the farmer, including increasing efficiency and reducing tillage.”

  • The world’s newest environmental watchdog is a satellite

    The world’s newest environmental watchdog is a satellite

    The new Sentinel-1a will monitor oil spills, sea beds, natural disasters, and aid in humanitarian crises

    , GlobalPost

    The world's newest environmental watchdog is a satellite (Credit: AP)
    This article originally appeared on GlobalPost.

    Global Post With great power comes great responsibility and the Sentinel-1a definitely fits the bill.

    The Sentinel-1a satellite was launched two weeks ago as part of the Copernicus project jointly funded by the European Union and European Space Agency (ESA). Its mission? To use its high-tech capabilities to monitor oil spills, sea beds, natural disasters and aid in humanitarian crises.

    It’s the first of six satellites Copernicus plans to launch and the program “will be the most efficient and fullest Earth-observation programme in the world,” according to Jose Manuel Barroso, the president of the European Commission.

    On Thursday, the satellite sent its first images of Earth down from space. This is what the 8.4 billion euro ($11.6 billion) project has produced so far:

    Sentinel-1a uses radar data which is useful for mapping natural disasters such as floods and earthquakes. It managed to produce this image of flooding in the Caprivi plain in Namibia on Thursday in just three hours — a task that used to take Europe’s previous Earth observation satellite much longer. And, the Sentinel can work in the dark or under cloud cover, as it did with this Namibia image.

    Such data would not only help policy makers respond to emergencies, but could also help develop environmental legislation.

    Additionally, the Sentinel-1a is able to distinguish among the several infrastructural elements of a city. In the image it captured of Brussels, Sentinel-1a showed green in places with vegetation, “red-blue to urban areas, white to high-density urban areas and black to waterways and low-reflective areas such as airport runways,” according to the ESA.

    Still in its initial launch and orbit phase (orbiting at 693 km above the Earth), the mission is expected to begin its operations in three months.

    All of the Sentinel’s data can be downloaded free-of-charge for members of the public and private sectors. This service can benefit businesses who can use these images “to help deliver data to farmers on soil moisture or pest infestation, help oil companies decide where to drill new wells or make it easier for insurers to assess the risk of costly floods and fires,” according to Reuters.

    However, many people are already skeptical of Sentinel-1a’s operations as its other uses include military and civilian surveillance. As the Telegraph noted, its imaging capabilities would be used for “common security and defense missions and operations.”

    For now, the EU and ESA have other matters to worry about — its rivals (like the American Global Positioning System, or GPS, Russia’s GLONASS and China’s new Beidou system) and falling space debris.

    “Maybe once or twice a year, you have to give yourself a little nudge to get out of the way of something,” explained Ian Shurmer, Sentinel-1a’s operational team leader. “We just pushed Sentinel-1a down by about 50m to make sure nothing happened.”

  • Retirement is not for bludgers

    Coming of Age

    Retirement is not for bludgers

    April 21, 2014
    older volunteer

    Life starts at 60. That’s the topic I was asked to address in a recent talk. But I insisted on putting a question mark at the end. Does it? It’s fashionable to think we’ll be reborn in our sixties into a world of pleasure and leisure. But really, it’s nonsense. By the time you reach 60 to a large extent you’ve made your life. Through good and bad luck, hard work and temperament you’ve got the structures in place – or you don’t. You’ve arrived at your sixth decade single and happily independent, or with a partner you still like. You’ve got there with money or with debt, with a network of reliable friends, with a home; or you maybe none of these things. If through bad luck, bad decisions, or a bad marriage you’ve arrived at 60 lacking secure foundations, it’s tough to build a new life. Ask men who’ve let friendships lapse about finding a network of buddies post-60; ask older women on the Newstart Allowance. “Life starts at 60” can sound pretty glib to the significant minority of older people who’ve fallen on hard times.

    Fortunately most of us do have the basics in place. We’ve to a large extent made our life. Phew, we’ve got here. We’re the advantaged ones. We’ve reached our 60s with options and opportunities. I’m among you, enormously privileged. I had great parents, good state education, good men who loved me. I’ve had a happy career in journalism. I was there in the golden era. So the question for us is how do we live our lives now? For those of us on secure foundations, who’ve bit by bit pieced a good life together, how do we continue to contribute? Retirement need not mark the point where our contribution is no longer expected or necessary. Retirement should not mark the start of the Me decades.

    Australians’ view of retirement has changed over the years. In the 1950s, retirement was a time of rest. Men broken by blue-collar jobs they’d started at 15 needed to recover. In the 1970s retirement was a reward: in return for years of labour and taxes society owed you the Age Pension and a few years of leisure before you died. By the 1990s retirement was seen as a right. It was a time of R&R – rest and recreation – cruises and grey nomading. The super industry cranked up expectations of retirement to include overseas holidays, air conditioning, restaurant meals, wine, and top rate private health insurance.

    But just because we’re retired and no longer paying taxes, doesn’t mean society owes us 20 or 25 years of leisure. Just because we’re retired doesn’t mean we’re tired, as the Boston writer Ellen Goodman has said. Most of us are not physically broken by our desk jobs. A new mindset is needed for these years. We’re healthier, better educated than past generations of retirees. We don’t think old age starts at 65 as our grandparents did. Here’s a new R&R approach to retirement – it’s about renewal and responsibility.

    Retirement is definitely an opportunity for personal renewal. Freed of the pressure to strive and compete, we can finally tap the nicer person lurking within – the more relaxed, well-rested, unhurried one. Surveys show people in their mid-60s are happy – possibly the happiest we’ll ever be. In our youth many of us were anxious and self-conscious. As we near the end of our lives, our sense of well-being dips again. But this is the sweet spot. If our retirement’s been voluntary not forced, if we’ve got those foundations in place, this can be a golden time to try new things, to get into shape, to travel, to spend more time doing what we love. Some people do find “encore” careers, and late-life divorcees do find “encore” loves. As a UK survey showed, people at this age can feel more vital than at any time since their thirties.

    But it’s also a time to give back, to be responsible citizens. I think many people in their 60s and older have already adopted this new R&R approach to retirement. They’re giving back or looking for opportunities to give back. Some care for grandchildren or elderly parents, or help out financially. In total older Australians give $22 billion a year to help their adult children. Many volunteer – though the main age bracket for volunteering is 45-54, not retirees. Some older people are concerned about the environment, climate change, housing affordability, the legacy being left the next generations. They’re involved in organisations that are trying to make Australia a fairer place. In the US they have a term, “selfish geezers,” to describe well-off older people who get roused only when their own financial interests are threatened. But that’s far from a representative picture.

    So in this new retirement era, this period of personal renewal and social responsibility, some of us find it’s all about balance again. Just as we tried in midlife to strike the right balance between work and family, so we’re juggling again. This time the balance we seek is between nurturing our relationships, and contributing to the wider society. It’s between being more relaxed, and being bored. It’s between having leisure and having purpose. In 15 years it might be time to grab a Me Decade, a period to reflect on the life we’ve made. But right now we’re busy living it.

    Labor and Liberals both struck down with NSW disease

    Structural impediments in both parties mean the medicine prescribed – democratisation – is a bitter pill to swallow

    Friday 18 April 2014 18.52 EST

    Barry O’Farrell’s fall, Joe Bullock’s victory, Arthur Sinodinos’s woes, John Faulkner’s call for reform – so many of the dramas dominating the political debate have a common thread: the power structures of the major parties.

    Both big political parties in Australia are built in a way that allows enormous influence to be wielded by a few factional powerbrokers.

    Those powerbrokers often value loyalty over quality in the selecting of parliamentary candidates, their backroom influence disenfranchises most party members who – not surprisingly – leave, and this structure opens the real risk of corruption, because influence peddlers thrive best when power is concentrated in the hands of a few. In both parties the problem appears to be at its worst in the state of NSW.

    It’s an organisational weakness most prevalent, acknowledged and analysed in the Labor party.

    Veteran senator and reform-supporter John Faulkner recently wrote to NSW party members, pointing out that it was their party’s own culture that made possible the kind of corruption being exposed by the Independent Commission against Corruption (Icac).

    “Our present system rewards intrigue, trading favours and doing deals. Eddie Obeid, Ian Macdonald or their ilk would not be able to win preselection in a genuinely democratic process where all party members cast a vote. Their success depended on nothing but factional anointment, they required no support beyond the leadership of a faction,” he said.

    Union-based factional power blocs also did the self-serving deal that elevated Joe Bullock to the number one spot on the WA Senate ticket, a man who has publicly declared he thinks many of the ALP members he is supposed to be representing are “mad”.

    Faulkner proposes grassroots pre-selections for upper house candidates at state and federal level as part of a solution.

    But his diagnosis of what ails the party to which he has devoted his working life does not sound all that different from what Liberal reformer John Ruddick says is wrong with his side of the political divide.

    “We have a preselection system which has been manipulated so that all the real power has ended up in the hands of three or four people, with maybe a dozen others who do their bidding, and those people become very attractive to the commercial world and to lobbyists because they have power within the party and over many of the sitting politicians,” says Ruddick of the NSW Liberal party.

    In fact, as Icac is revealing, lobbyist Nick Di Girolamo, who drew both Arthur Sinodinos and Barry O’Farrell into Icac’s orbit, and Labor powerbroker Eddie Obeid, were often working together. And despite neither Sinodinos nor O’Farrell having been accused of corruption, they have each now paid the price for the system they worked within.

    And, like Faulkner, Ruddick sees democratisation as the remedy – he wants electorate plebiscites for lower house preselections and statewide plebiscites for the upper house.

    Former Liberal MP Ross Cameron is also calling for an end to the delegate-based voting systems in the NSW Liberal party in order to get rid of “the incentives for factionalism, branch stacking and lobbyist control”.

    But Liberal and Labor would-be reformers face the same dilemma – the powerbrokers who benefit from the current system also control the structures that might change it.

    On the Labor side, reform is incremental because the union-based power blocks control the state and national conferences which have to implement any changes to the system. Once those forces had had their way, the groundswell for reform that built before Labor’s last national conference in 2011 petered out into yet another committee, which appears to have done nothing much at all.

    Labor leader Bill Shorten will give a delayed speech about his plans for reform next Tuesday, but will face similar opposition in the lead-up to Labor’s national conference next year.

    On the Liberal side, Tony Abbott also supports change and last year announced an “eminent person’s committee” to look at reforming the NSW party – led by former prime minister John Howard. It is likely to present a reform plan next month ahead of the state council meeting in September.

    But, according to Ruddick, the state council is a “gerrymander”, with factional leaders creating new “on-paper” branches that meet at most once a year in order to elect a delegate to state council and keep hold of “the numbers” – presenting Liberal reformers with exactly the same structural impediment to change as is faced by Labor.

    But after the shock of O’Farrell’s sudden demise and new premier Mike Baird promising to “return confidence” to the political system, reformers like Ruddick are feeling more confident than they have for a while. (Until Wednesday, Ruddick was facing expulsion from the Liberal party for publicly speaking his mind.)

    The new NSW premier is also vowing to “take action” on lobbyists. Ruddick thinks this should include banning “in-house” lobbyists from holding party executive positions, on top of the ban of “third-party” lobbyists, which Abbott instituted after the federal election.

    A ban like that would have an immediate impact. NSW Liberal party president, Chris Downy, is the chief executive of the Australian Wagering Council, which lobbies on behalf of the online gambling industry. The treasurer, Peter McGauran, is the chief executive of the Australian Racing Board.

    But, according to the reformers, without “democratisation” of party processes, any crackdown on lobbyists would not end the root cause of the problem.

    Meanwhile, as my colleague Gabrielle Chan has reported, independents like Cathy McGowan, Tony Windsor and Andrew Wilkie are facing a surge of interest from people wanting to run community campaigns to challenge major party politics.

    Turns out voters respond to candidates and parties who listen, engage them, give them a say and don’t appear to be mostly interested in shoring up their own interests and power. Who knew?

    Actually, both major parties know it. They just can’t quite work out how to change.

  • Australian Politics and the Neoliberal Experiment

    Australian Politics and the Neoliberal Experiment

    The Neoliberal Economic experiment has failed.

    The Global Financial Collapse is really the only evidence we need.

    But why are we failing to move on politically?

    Unfortunately the political parties formed around conducting this experiment are extremely large and well financed.
    We have allowed them to take up a position in the public narrative as ‘good economic managers’.

    This must end.

    Parties such as the Liberals in Australia, the Republicans in America and the Tories in the UK have been playing economics by a rulebook – Capitalism and Freedom – written by the economist Milton Friedman at the Chicago School of Economics in 1962.

    This vision of a shrinking government with ever-diminishing controls on ‘the market’ (corporations) extolled two benchmark policies;

    • deregulation (cutting red tape) and;
    • privatisation (sale of public assets and services).

    Its main justifications were that government-run institutions are inherently inefficient and wasteful, that government employees are not motivated to provide the best service for their clients, and that corporations are inherently driven to compete, thereby ‘the market’ will penalise them for being inefficient.

    There are two main problems with this…
    1. Corporations that are allowed to run government inherently act in their own best interest – to increase profits, not in the interest of people.
    2. Corporations with this power also act against corporations that don’t have ‘the ear of government’ – this results in an increase in anti-competitive monopolies that have no competition.

    The results are clear to see.
    Removal of regulations in the US led to monopolistic financial institutions lending vast sums of money in a greedy race for interest. The result has been the biggest public bail-outs the world has ever seen and a global collapse in market confidence unprecedented even by the great depression.

    Australia under Kevin Rudd and Wayne Swan managed to steer away from this plummet in confidence by a swift and targeted government spending package. This action was supported by the antithesis to Friedman’s ‘free-market’ model – the economic model of John Maynard Keynes.

    This action was singular in the world, as most governments were trying to shut the gate after the horse had bolted – dictating ‘austerity’ or a decrease in all government spending. In Europe this has been especially devastating. Greece, Spain, Italy and Ireland have been the worst affected, and Germany has had to take the reins of their economies to avoid a complete collapse of the Euro.

    Somehow the Labor party in Australia has allowed these events to slide out of public view.
    By buying into a media war with Liberals over a concocted soap opera of leadership struggles and a ridiculous racially-fuelled fear that we are about to be swamped with rich queue-jumping ‘boat people’ Labor has allowed the public narrative to slide into a dumb abyss.

    Only the Greens now hold a reasonably unblemished record of supporting a higher public narrative of true leadership. Unfortunately our monopolistic media environment has cast them unfairly in the public mind (over many decades) as a ‘one issue’ party with no policies and leanings towards communism. These perceptions will take a LOT of public discussion on twitter to overcome, but the signs are already apparent…

    We cannot allow the hard work of generations of unionists to disappear overnight.
    The Labor party must join with the Greens to reinstate a rational public narrative; in spite of Rupert Murdoch.

    For this there is one main barrier; Labor is supported financially by corporations with a greater say than it’s own members and unions in how the party platform will be implemented when in government.

    What promises are made publicly before an election are restricted by pandering to these donors. We have even seen a popular elected Prime Minister removed from office for trying to implement a reasonable tax on mining companies.

    These are dangerous times for Labor, and therefore for the Australian people.
    Our own economic collapse is not far away if we do not diversify our economy.
    Pandering to the most vocal, greedy and monopolistic mining corporations (supported by the banks, developers and insurers) can no longer be the role of Labor.
    A great divorce must take place.

    There is a benefit to this taking place.
    The Liberals are standing on one leg.
    The only thing they stand for is protecting the corporate interests of a few.

    The only card they can play is bombarding the public with advertisements.
    Allow them to play that card.

    My advice to the Australian Labor Party;
    Reintroduce the original robust mining tax as the MAIN way of diversifying and saving our economy.
    It is.

    Let them spend every cent they have at their disposal driving the general public up the proverbial wall with negative advertising. And go viral with your own message. We will support you.
