Could we refill the Great Artesian Basin with floodwater? › Ask an Expert (ABC Science) If we can tap the Artesian Basin to take water out, why can't we pump water back into it in times of flood ? It's a temptingly simple idea that in times of flood we can inject surplus water back into the Great Artesian Basin. But while reinjection is technically feasible, the trick is to collect that water and inject it into the right locations, and the sheer size of the artesian basin makes that difficult, says Dr Vincent Post, from the National Centre for Groundwater Research and Training. The Great Artesian Basin underlies 22 per cent of the continent stretching across Queensland to the south east corner of the Northern Territory, north east corner of South Australia and northern New South Wales. But it is not just one big underground lake. The water is confined and pressurised within a massive geological formation of porous sandstone, known as an aquifer, where it flows and is stored in different ways. ^ to top Pressure problems "In principle we could," says Post.
Great Artesian Basin. Great Artesian Basin in Australia Hot water bore hole into the Great Artesian Basin in Thargomindah The Great Artesian Basin, located within Australia, is the largest and deepest artesian basin in the world, stretching over 1,700,000 square kilometres (660,000 sq mi), with measured temperatures ranging from 30–100 °C (86–212 °F). The basin provides the only reliable source of fresh water through much of inland Australia. The Basin underlies 23% of the continent, including the states and territories of Queensland (most of), the Northern Territory (the south-east corner of), South Australia (the north-east part of), and New South Wales (northern part of). The basin is 3,000 metres (9,800 ft) deep in places and is estimated to contain 64,900 cubic kilometres (15,600 cu mi) of groundwater. The Great Artesian Basin Coordinating Committee (GABCC) coordinates activity between the various levels of government and community organisations.
Physiography Geology Water source Water in, water out: assessing the future of the Great Artesian Basin. The Great Artesian Basin is huge and ancient underground “water tank” big enough to fill Sydney Harbour 130,000 times. It streches from Cape York down to Dubbo and further west than Coober Pedy and has been providing the only reliable source of fresh water for rural communities in Queensland, New South Wales, South Australia and the Northern Territory since the first bore holes were sunk in the 19th century. But new interactions between industries such as agriculture, mining and the water itself has prompted the big question: how does the Great Artesian Basin really work? Great Artesian Basin Water Resource Assessment was released this week.
It’s the most comprehensive assessment to date of the Basin’s water flows and physical structure (its hydrology and geology). This was a challenging project. In fact, the complexity of the geological structures and their role in governing groundwater conditions was one of the big surprises of this assessment. Click to enlarge.

On the afternoon of September 15th, in the small northern California town of Weed, a fire began burning in the dry grass near the Boles Creek Apartments.
By day’s end, it had consumed about a quarter of the town, moving so quickly that many residents fled empty-handed from their homes, some of them half dressed. Though Weed is famous for its wind—the town’s much lampooned name is the legacy of Abner Weed, a sawmill operator who was looking for a place to dry his lumber—never before had that wind combined with heat and drought to such destructive ends. As much of the American West gets warmer and drier, wildfire season is getting longer, busier, and more frightening.
But fire, unlike other natural hazards, is still widely considered an enemy to be defeated, rather than a fact of life that must be accepted. There have been attempts, especially in the past two decades, to change this tendency. “We don’t just have a forest-fire problem,” Moritz told me. Dairy industry australia.

With its system of applied education, research and citizen- led design permaculture has grown a popular web of global networks and developed into a global social movement. The term permaculture was developed and coined by David Holmgren, then a graduate student at the Tasmanian College of Advanced Education's Department of Environmental Design, and Bill Mollison, senior lecturer in Environmental Psychology at University of Tasmania, in 1978.  The word permaculture originally referred to "permanent agriculture", but was expanded to stand also for "permanent culture", as it was understood that social aspects were integral to a truly sustainable system as inspired by Masanobu Fukuoka’s natural farming philosophy.
It has many branches that include, but are not limited to, ecological design, ecological engineering, regenerative design, environmental design, and construction. History Several individuals revolutionized the branch of permaculture. In Australian P.A. Department of Agriculture (Australia) The Australian Department of Agriculture is a department of the Government of Australia charged with the responsibility to develop and implement policies and programs that ensure Australia's agricultural, fisheries, food and forestry industries remain competitive, profitable and sustainable. DAFF policies and programs: encourage and support sustainable natural resource use and managementprotect the health and safety of plant and animal industriesenable industries to adapt to compete in a fast-changing international and economic environmenthelp improve market access and market performance for the agricultural and food sectorencourage and assist industries to adopt new technology and practicesassist primary producers and the food industry to develop business and marketing skills, and to be financially self-reliant.
The department facilitates the development of self-reliant, profitable, competitive and sustainable Australian farm businesses and industries. Barnaby Joyce wants cheap loans for farmers, but will it help small business? The outcome of Agriculture Minister Barnaby Joyce’s calls for the federal government to offer an extra $280 million in cheap loans to embattled farmers could have flow-on effects to rural small businesses, the National Farmers Federation suggests. Joyce wants the loans to be given at highly discounted interest rates to farmers having trouble paying off commercial bank debts, in addition to the $420 million Farm Finance loan package which was released in 2013. Last week Joyce said he was in favour of a Rural Reconstruction and Development Bank within the Reserve Bank, which could take on poor rural loans from the private sector at a discounted price. Yesterday he was touring drought-stricken regional communities, accompanied by Prime Minister Tony Abbott. Joyce told wool and meat producers in Broken Hill that the farmers were “doing a decent thing for our nation”, The Australian reports.
The government is yet to confirm the size of the relief package it will offer farmers. Victorian State Government's Department of Primary Industries. Ech2o consultants ltd: Articles by ech2o. Stephen Choi (Adapted with generous permission from: Mary Casey, Simone Concha, Jonathon Dalton, Lella Durante, and Joe Karten) Having only moved to Australia, a year and a half ago, I feel somewhat over-whelmed and under-qualified to be sharing my views on Australia’s ‘water issues’. So where do I begin?
Well, I decided that it would be easy to write about a country where flooding and drought can happen in the same day, or to recall the latest facts about yet another nation that is facing major challenges due to climate change, climate variability and reduced water availability1. But, I decided, you can look that up for yourselves! The Big Dry and the Water Police In the world’s driest inhabited continent, water quality and availability is under enormous pressure2. A lot of people thought that The Big Dry was quite fun at first – it was something to joke about over the barbie, or an excuse to shower with someone you liked.
So what did the people do? Different folks, different attitudes.
