Latest News 8 February 2016, The Conversation, In a heatwave, the leafy suburbs are even more advantaged. Summer brings out the heliophobe in many of us. It’s manageable if you live in a house that stays cool when shut up tight. It helps if you’re physically capable of crossing to the shadier side of a hot street. It’s even better if you can work from home or use public transport stops that enjoy the cover of buildings or trees. We have reason to think a lot about shade these days, especially as the heatwaves roll in. At such times, shade is our friend. On top of the existing urban heat island effect, the incidence of extreme heat events is rising. These events are also lasting longer and getting hotter. Coverage for all is a wonderful ideal, and the federal government has announced plans to set “urban canopy” targets. But, in the meantime, some communities and areas need trees more urgently than others. Shade is not only a matter of public health; it is a social equity issue. In a warming city like Melbourne, some of the most socially vulnerable people are in areas that are most exposed to extreme heat. Our pilot research in Melbourne suggests that integrated social and ecological data sets should be used to develop programs that reduce socioecological vulnerability. Shade can be a life-saver More than twice as many people perished in Melbourne during the 2009 heatwave leading up to Black Saturday than died in the devastating fires on that day. Extreme heat is a slow-motion disaster. The tendency to respond to heat as an emergency rather than planning for an ongoing chronic stress can have deadly consequences, as Annie Bolitho and Fiona Miller argue in a forthcoming paper. Extreme heat events are increasing in duration and intensity, and some parts of cities are more vulnerable than others. AAP/Bureau of MeteorologySocial and geographic isolation, age, disability and existing health conditions all play a role in vulnerability to heat. Vulnerability to urban heat also has a geography: vulnerability is compounded by where people live and whether trees live there with them. Urban authorities are using vegetation to help fight extreme heat in susceptible areas. In large sprawling cities like Melbourne, local councils are working to increase canopy cover in their jurisdictions. Urban forests can mitigate the urban heat island effect and significantly lower surface and ambient air temperatures.

Queensland’s resources industry has called on the state and federal governments for help to save thousands of jobs after a study showed that a third of the state’s coalmines are running at a loss. The report, commissioned by the Queensland Resources Council (QRC), also found that more than half of the mines producing thermal coal for power stations were losing money. “It’s really time for government to sit down with the industry and see what we can do to hang onto the jobs we’ve got,” the chief executive of QRC, Michael Roche, told ABC radio. Roche said governments must consider what support could be given to the industry, such as tax relief. He said conditions were some of the worst faced in decades. But the anti-mining group Lock the Gate said it was “outrageous” for miners to claim more help from the state government, which he said already gave $3bn a year in various subsidies to the industry. “The industry is inherently cyclical and there is no case for industry relief. The industry should have been prepared for the inevitable downturn,” said spokesman Drew Hutton. “Mining is a long-term business and it obviously did a very poor job in managing its cashflow. The Queensland government must resist subsidising mining and rewarding them for poorly managing their businesses.” Roche estimated that 21,000 jobs had been lost in the industry in Queensland in the past two years as demand from China has slowed and commodity prices have plunged. “We would like government to think about what we need to do to protect the remaining 60,000 jobs in the Queensland resources sector,” Roche said. But Lock The Gate said the industry provided less than 3% of jobs in Queensland and that rehabilitating the landscape from the impact of open-cut coal mining in particular would create far more employment than financial relief for existing operations.

Europe and the United States tried to bridge differences over emissions standards for aircraft on Sunday as global aviation leaders prepared to adopt new rules that could affect Boeing Co and Airbus Group’s production of the largest jetliners and freighters. Proposals being debated in Montreal by the International Civil Aviation Organization (ICAO), the United Nations’ aviation agency, would force makers of the world’s largest passenger jets to upgrade or stop producing certain models as early as 2023, according to sources close to the negotiations and documents seen by Reuters. U.S. and European negotiators are trying to come up with the world’s first carbon dioxide emissions standards for aircraft as part of the industry’s contribution to efforts to combat climate change. Aviation was not included in the global climate deal agreed by a UN conference in Paris in December, but ICAO is trying to nail down the first of its two-part strategy as soon as Monday after six years of talks. It is due to finalize a market-based mechanism for all airlines later this year. Differences remain on where to place the bar on efficiency, with the United States and Canada pushing for more stringent targets than the European Union, while environmental groups have accused Europe of dragging its feet. “The CO2 standard will push industry to be as fuel-efficient as possible in all market conditions to reduce GHG (greenhouse gas) emissions and the impact of aviation on climate change,” stated the Canadian paper presented at ICAO last week.

He was the leader of the Coalition government who thought that climate change was crap, dismantled the carbon price, trashed the Climate Council, and tried to dismantle the Climate Change Authority, the Australian Renewable Energy Agency and the Clean Energy Finance Corp. Tony Abbott brought investment in large scale renewable energy to a screeching halt by threatening to kill the renewable energy target, and then cutting it sharply, so encouraging a capital strike by major utilities. He also threatened to decimate the ranks of climate scientists through major cuts to the CSIRO. He said he hated the sight of wind farms, and said he thought coal was good for humanity. Remember Malcolm Turnbull? He was the former Opposition leader who enthusiastically launched the Beyond Zero Emissions Plan for a rapid transition to 100 per cent renewable energy in Australia in 2010, who spoke of the moral and economic importance of acting decisively on climate change, who spoke of Direct Action as “irresponsible” and a “fig leaf” for a climate policy, and who spoke of many fine Liberal policy initiatives in whole sentences. Nearly six months ago, something strange happened. Malcolm Turnbull became prime minister after Tony Abbott was dumped by his own party. But nothing changed. If the swap had been made by deed poll or a cardboard cut-out, the practical impact on climate and clean energy policies would have been no greater. The carbon price is still scrapped, the “fig leaf” remains the centrepiece of the great policy misnomer Direct Action; Australia’s emissions are surging to a record high; the capital strike by utilities continues and large scale renewables investment remains at zero; the legislation to repeal the CCA, ARENA and the CEFC has not been withdrawn; coal is still considered good for humanity, and even a solution to hunger; and 300 or so climate scientists have just been told, in the parlance of modern football, to “do one” by the CSIRO and find another job. Yet, in spite of all this, all Turnbull needs to do to be assured of election victory this year – in the absence of a credible opposition leader – is to make sure he does not actually morph into Tony Abbott. That means woo-ing the “soft centre” who chose to believe – like they did in 2013 – that Tony Abbott would “do the right thing”, despite all the evidence to the contrary. In fact, Malcolm Turnbull doesn’t even need to be Malcolm Turnbull. He certainly doesn’t need to drop Abbott’s policies, and appears to have made a promise not to. A new composite figure, call him Malcolm Abbott or Tony Turnbull, has emerged. How do we know this? Here’s five reasons why: Read More here End Latest News Change in water availability compared with average 1961 – 1990 Interactive: How climate change shapes food insecurity across the world 1 December 2015, Carbon Brief: Rising temperatures and more extreme weather are set to increase the pressure on food supplies around the world, risking shortages in the least-developed and developing countries and potentially pushing millions of people into deeper hunger and malnutrition. This is the message from the Met Office and the United Nations World Food Programme (WFP), who have joined forces to launch a new interactive map at the COP21 conference underway in Paris.

But it’s becoming increasingly necessary––this video digs into some of the ways people have come to accept it. Source: Holly Kaw! Do we drink recycled water in Australia? Depending on where you live, or where you’ve travelled, there’s a chance you’ve already drunk recycled water. Water recycling happens in other regions of Australia but the water is generally directed exclusively for irrigation or industrial use. Recycled water overseas FCA is an alliance of farmers and leaders in agriculture who are working with their peers, the wider sector and decision-makers to make sure Australia takes the actions necessary to address damage to our climate. FCA is determined to see farmers and agriculture get the support and investment it needs to adapt to a changing climate, as well as be part of the solution. Members are spread far and wide across the country: from the tropical north of Queensland to Tasmania, and from the wine growing regions of Western Australia right across to the sheep and cropping farms of New South Wales. Farmers for Climate Action is an associate member of the National Farmers Federation, and a member of the Climate Action Network Australia (CANA). We work closely with stakeholders within the agricultural and climate realms. Learn more about Farmers for Climate Action here 26 December 2016, Climate News Network. An internet tool is now available that helps to quantify and control farms’ greenhouse emissions released during the crop production cycle. It’s called the Cool Farm Tool (CFT) – an easy-to-use online calculator that helps farmers monitor their emissions of greenhouse gases. Agriculture accounts for about 15% of total global greenhouse gas emissions, though when fertiliser manufacture and use and the overall food processing sector are included in calculations, that figure is considerably higher. The land can also act as a vital carbon sink, soaking up or sequestering vast amounts of carbon: when soils are disturbed the carbon is released, adding to greenhouse gases in the atmosphere. The CFT was initially developed by researchers at the University of Aberdeen in the UK in partnership with Unilever and the Sustainable Food Lab. Now managed by a group including academics and food manufacturers called the Cool Farm Alliance, the CFT is free for farmers to download. Various details, including the crops being planted, soil types and pH levels (the relative acidity or alkalinity of the land), are entered into a series of boxes. Moisture levels, amounts and types of fertiliser used and general management details are also entered, along with information on quantities of diesel and electricity used in the cultivation and storage of crops and the fuel needed to transport goods on and off the farm. Read More here The Cool Farm Tool covers virtually all crops and livestock globally. One exception is for crops grown in non-soil media (e.g. greenhouses or hydroponically), but proxies can be used. The Tool is undergoing an update for livestock including new emission factors for feed, and improvements to the user interface. A project is also underway to improve ease of use and applicability of the Cool Farm Tool for many perennial and multi-year crops (coffee, tea, orchard crops, berries). Results from both projects are due in 2017.

Australia is extremely vulnerable to disruptions in food supply through extreme weather events. Climate change is the most challenging threat to food and water security between now and 2050 Water risks like stress and variable supply threaten everything from agriculture to industry to energy production. Already, 69 countries and one-quarter of the world’s cropland face high water stress. These challenges will likely become more severe as competition for water increases and climate change shifts precipitation patterns. The World Economic Forum identified global water crises as one of the top five global risks for businesses. Without tools to evaluate these risks and inform management plans, businesses’ bottom lines will suffer. Read More here UNEP: The real concern for the future, in the context of changing patterns of rainfall, is the decrease of run-off water which may put at risk large areas of arable land. The map shows how seriously this issue must be taken, while the forecast indicates that some of the richest arable regions (Europe, United States, parts of Brazil, southern Africa) are threatened with a significant reduction of run-off water, resulting in a lack of water for rain-fed agriculture and thus putting millions at risks. The accelerating changes in our global climate will undoubtedly cause major changes in the patterns of water cycle and geographical distribution, in the near future. Some regions will receive less precipitation, some more, and this will significantly affect agricultural activity. While some regions will see a reduction in arable land, others will have more suitable land for agriculture. It’s likely that certain types of agriculture will migrate and traditional areas for crops will change. In other words, climate change will alter the geography of traditional crop areas, which may impact on the world’s capacity to provide enough food for all. Since the 1990s, the scientific community has been warning about the rapidly changing climate, endeavouring to convince people to take urgent measures to mitigate the changes. These multiple warnings have been ignored until very recently, but the issue is now a priority with many international organizations. However, all reliable climate scenarios run by the IPCC and published in the fourth assessment reports show the following results: In other words, ongoing climate change will mean that the water supply for human communities will become more and more uncertain. The IPCC has stated that between 2000 and 2005 in the northern hemisphere, climate change accelerated faster than predicted, with the consequence that the water cycle could change in an unpredictable way, leading to the possibility of increases in extreme weather. The fear is that with all these changes, even if the quantity of water in the world does not change, the level of accessibility of the theoretically available water may significantly change. Source: UNEP Future Directions International highlights Australia’s challenge BOM water information and update sites 3 August 2015, The Conversation, The role of water in Australia’s uncertain future: If you live in an Australian city, there’s a good chance that your water comes from surface water such as streams, rivers and reservoirs filled by rainfall and runoff. If you live in Perth, much of your water (about 40%) comes from groundwater. But you might be surprised to know that a sizeable proportion of water in Australia came from recycling or desalination in 2013-14. 39% of Perth’s water came from desalination and 41% of Adelaide’s. All cities also used small portions of recycled water: Melbourne (4%), Sydney (7%), southeast Queensland (7%), and Canberra (8%). The Bureau of Meteorology recently released, for the first time, comprehensive national data on these “climate-resilient” water sources, through a new online portal provided as part of the Bureau’s Improving Water Information program. Climate-resilient water sources are those on which climate variability, such as variations in rainfall, temperature and drought, has little or no influence. The data set provides information on two of the most significant such sources: desalination and water recycling. The Climate Resilient Water Sources web portal is an interactive site providing comprehensive mapping and information of desalinated and recycled water sources for over 350 sites across Australia, both publicly and privately owned and operated. Users can access the portal, to search information on capacity, production, location and use of these alternative water sources across Australia. How many desalination and recycled water plants does Australia have? Below you can see the amount of desalinated and recycled water sourced for Australia’s cities in 2013–14 from the National Performance Report released in May 2015. From the Climate Resilient Water Source data we can also see which parts of Australia have the greatest climate resilient capacity compared to their sourced water (including surface, ground, recycled water and desalination). Western Australia has greater climate resilient capacity than its total water sourced in 2013–14, as you can see in the chart below: We can also see that more than 50% of reported production of recycled or desalinated water in 2012-13 (410,491 ML) was for urban use (residential, domestic, commercial, industrial, municipal). Read More here Improving Water Information: data, status and forecasts Australia’s variable climate drivers Weather and climate drivers: Floods, drought, and climate change are all driven by a number of processes in the atmosphere and oceans but the changes are driven at different timescales. The drivers shown in the map interact with each other and influence different parts of the continent to bring local weather and climate. The drivers include circulation patterns in the Pacific Ocean that bring El Niño conditions associated with drought in eastern Australia and La Niña conditions that are associated with floods. The Indian Ocean Dipole is a similar pattern in the Indian Ocean that can bring drought to south-west and south-east Australia, and the Southern Annular Mode are the major influences on rainfall (and thus runoff) in Australia. For more detail visit BOM here. Relatively small changes in rainfall are amplified to much larger changes in runoff and groundwater recharge, which make Australia’s water resources the most variable in the world. Water management is highly adapted to this variability, but the millennium drought in south-east Australia and the sharp drop in runoff in the South West of Western Australia since 1975 have tested the effectiveness of these adaptations. New measures are being introduced such as urban water supplies that are less dependent on runoff and the return of water to the environment to make it more sustainable. Climate change is occurring on top of that variability and in southern Australia it is likely to further reduce water resources. For the moderate climate change predicted to occur by 2030, the adaptation to droughts and floods can be effective, because the worst consequences are likely to be more intense droughts and less frequent but more intense floods. For further climate change, projected to occur by 2050 or 2070, the conditions of the millennium drought might become the average future water availability, which would have profound consequences for the way water is used and for ecosystems. The understanding of how climate influences water can help make water management more adaptable, such as through improved seasonal forecasts, and it can help communities plan how they will respond to reduced water availability in future. Source: CSIRO Water 7 climate chapter 3 from Water – Science & Solutions Report Understanding the ENSO Influence Source: BOM ENSO Wrap-up Groundwater use is increasing across Australia but the total use is difficult to estimate. Most groundwater is extracted by individual users and is rarely metered, and only a small fraction is managed through distribution networks. In 2004–05, licences for groundwater use were about 4700 GL/year, or 25% of the total amount of water consumed in Australia.2,3 Unlicensed use of groundwater – mainly for stock and domestic uses – is estimated to consume an additional 1100 GL/year.4 The amount of groundwater used is estimated to have almost doubled since the mid 1980s. Increased use of groundwater has been facilitated by recent drilling technologies and cheap submersible pumps that can lift water from considerable depths. In the drier parts of Australia, groundwater is the predominant water source because surface water resources are so scarce. Perth and Alice Springs, for example, rely on groundwater for about 80 and 100% of their water supply, respectively. When surface water resources become scarce, users turn to groundwater to meet their needs. Declines in surface water availability during the millennium drought in the southern Murray–Darling Basin led to a modest rise in groundwater use (1240 GL in 2000–01 to 1531 GL in 2007–08), but a sharp rise in the proportion of water supplied from groundwater (11% to 37%).5 Given the reliability of supply and convenience of self supply, the use of groundwater may not return to previous levels, even when surface water availability does. Many aquifers with high historical rates of use are showing symptoms of over-use, such as falling water tables and lower aquifer pressures and subsequent impacts on future use, groundwater salinity, river flows, and ecosystems. The level of over-use was not recognised for decades because of the lags inherent in large, flat, and slow moving groundwater systems. Remediation of these systems is expensive and difficult because salinity and ecological damage are hard to reverse, and because of the historical expectation of reliable water supplies. Inadvertent impacts of recent strong growth in groundwater use have not been felt yet and, given that the consequences of present use are in many cases still to be felt, some caution should be exercised around future groundwater development, by putting effective risk assessment and management processes in place.

Government, industry and the general public can use these products to inform decision-making and research about groundwater resources. Groundwater information products: A third of the world’s biggest groundwater basins are in distress 16 June 2015, Two new studies led by UC Irvine using data from NASA Gravity Recovery and Climate Experiment satellites show that civilization is rapidly draining some of its largest groundwater basins, yet there is little to no accurate data about how much water remains in them. The result is that significant segments of Earth’s population are consuming groundwater quickly without knowing when it might run out, the researchers conclude. The findings appear today in Water Resources Research. “Available physical and chemical measurements are simply insufficient,” said UCI professor and principal investigator Jay Famiglietti, who is also the senior water scientist at NASA’s Jet Propulsion Laboratory. “Given how quickly we are consuming the world’s groundwater reserves, we need a coordinated global effort to determine how much is left.” The studies are the first to characterize groundwater losses via data from space, using readings generated by NASA’s twin GRACE satellites that measure dips and bumps in Earth’s gravity, which is affected by the weight of water. For the first paper, researchers examined the planet’s 37 largest aquifers between 2003 and 2013. The eight worst off were classified as overstressed, with nearly no natural replenishment to offset usage. Another five aquifers were found, in descending order, to be extremely or highly stressed, depending upon the level of replenishment in each — still in trouble but with some water flowing back into them. The most overburdened are in the world’s driest areas, which draw heavily on underground water. Climate change and population growth are expected to intensify the problem.

Source: Virtual Water, University of British Columbia Australia and the Global Food and Water Crisis Source: Water Scarcity and Future Challenges for Food Production Future Directions International preamble from their webpage regarding “Australia’s role in solving future global food and water crises”: Food and water insecurity are among the most formidable challenges facing the world. The potential for food or water crises to manifest between now and 2050 is high. If such events were to occur, they would lead to rising poverty levels, slowing growth and development, and widespread instability and conflict. Australia’s greatest responsibility and opportunity in the 21st century is to help feed a hungry world. Mobilisation of political will and an overhaul of the existing global food systems are critical to avert crises. To access Future Directions Reports: “Food and Water Security: Our Global Challenge”; The Forgotten Resource: Groundwater in Australia 28 May 2015, Future Directions International: Urban agriculture is becoming an increasingly prominent topic in discussions on food security in Australia. More than 90 per cent of Australia’s population lives in urban centres and depends on a decreasing agricultural workforce to meet increasing food demand. Long food supply chains, although economically efficient, lead to poor nutritional and environmental outcomes for society. The re-localisation of food production will support and enhance Australia’s food system and has the potential to increase access to nutritious, affordable food for the most vulnerable. Australia produces enough food to feed 60 million people, yet economic barriers leave an estimated 2 million Australians dependent on food relief annually. Foodbank Australia is reportedly struggling to meet demand; it turns away as many as 60,000 people each month due to a shortage of food. To enhance food security, efforts need to be focussed on overcoming the increasingly volatile food prices that are expected to occur as a result of increased production and energy costs and the effects of climate change. There is a strong consensus amongst academics and policy makers that urban agriculture is a viable means of increasing domestic food security. Urban agriculture has assisted communities in both developed and developing nations to cope with food insecurity, by ensuring local availability of nutritional and affordable food. Greater support, however, is required from the Federal, State and Local governments, to ensure that benefits can be realised within Australian cities. Read More here
Complexity of food distribution The ZCA Land Use Report outlines a range of measures that can substantially reduce emissions and provide opportunities for farmers in building resilience to the impacts of climate change. These measures encompass both agriculture and forestry and address emissions at the scale required to prevent catastrophic climate change. The Land Use Report analyses the suite of land use practices in Australia for their function as a source of greenhouse emissions, the potential of the landscape to draw down atmospheric CO2, and the likely impact of changes to land use patterns on local economies. The report provides a comprehensive assessment of how Australia can manage its productive capacity, ecological heritage and ecosystems services for the future.

Zero Carbon Australia Discussion Paper: Land Use: Agriculture and Forestry: Emissions in the agriculture and forestry sectors in Australia are high and growing. The UNFCCC National Inventory Report suggests that sources of land use emissions, such as land clearing for agriculture and enteric (intestinal) fermentation from digestive processes in livestock, contribute 15% of national emissions. Australia’s land use sector is in a unique position to mitigate (reduce) climate impacts and take a leading role in addressing climate change. Agriculture and forestry are the only sectors of the Australian economy that can draw carbon dioxide out of the atmosphere by sequestering it in growing plants and in the soil. The agriculture and forestry sectors can mitigate climate impacts on the land, bringing prosperity to rural areas in the process. The Zero Carbon Australia Land Use report explores how this can be done.
