This share varies markedly, however, and can reach up to 80% in parts of southern Europe, where irrigation of crops accounts for virtually all agricultural water use. Wastewater agriculture is used in countries where water purification isn't available or isn't cost-effective. The rest evaporates or is used by plants. Much of the land currently used for grazing animals will probably not have a valuable productive economic use if animals are removed from agriculture. The largest volume of irrigation water was applied to cotton, which used 26 per cent of the national irrigation total for the year, according to the Australian Bureau of Statistics. 0000001955 00000 n %PDF-1.5 %���� Issues facing Australian agriculture Political values. In industrialized nations, however, industries consume more than half of the water available for human use. According to the latest research from the Australian Bureau of Statistics, total water use on Australian farms decreased 3 per cent in 2015-16 to a total of 9.2 million mega litres, down 238,900 mega litres … `�i0��*F�tuL0e0?�X���V@�V&��Ǒ!����q�e��L��X,�0o�;P}p&c {���ljIn�Bs�^�&j20�d��m�`.

There are so many different kinds of farming, and different rainfalls …” At the same time, farms are learning how to exist using water more efficiently, and sparingly. Glossary 60 5 References 63 Appendix A. Estimates are presented at Australia, state & territories levels. There are no impacts in the 2018-19 estimates from more recent events including the COVID-19 pandemic, and from bushfire activity in New South Wales, Victoria and the Australian Capital Territory in late 2019 and early 2020. 0000074367 00000 n The gap between water supplies and water demand is increasing in many areas of the world: in those areas already suffering water lacking, increasing drought will be the major constraint to agricultural growth and development. 0000007285 00000 n As much as 50% of all food produced in the world ends up as waste every year according to figures from the Institution of Mechanical Engineers. Agricultural activities accounted for 6996 GL (about 50%) of total Australian water consumption in 2008–09. How much water do we use? 0000002633 00000 n In AQUASTAT, three types of water withdrawals are distinguished: self-abstracted agricultural, self-abstracted industrial and municipal (including domestic) water withdrawal. In 2018-19: In 2018-19: Average area rainfall across Australia was 352mm, down 20% year on year. That leaves us with only 1% of all the water on our Earth to use to grow crops, raise animals, cool coal fired power plants, power industry and home use. This is a decrease from 2004–05 (12 191 GL; 65%), reflecting restricted supplies during southern Australia’s extended drought. This land, in the extensive zone, is not suitable for any of the more economic uses listed above. Many farming areas across Australia experienced drought throughout 2019, with New South Wales and Queensland particularly impacted. “In most high-income countries and many emerging economies, agricultural pollution has overtaken contamination from settlements and industries as the main factor in the degradation of inland and coastal waters,” said Eduardo Mansur, Director of FAO’s Land and Water Division. 0000002071 00000 n The reality is that Australia’s support for farmers is among the most meagre in the world, second only to New Zealand in the OECD. Of the additional irrigation water purchased during 2018-19: Australian farms used a total of 8 million megalitres of water taken from various sources including: Impacts of drought are evident in agricultural activity estimates for the 2018-19 reference year across a number of the ABS' agricultural collections, including Water Use on Australian Farms. 0000016912 00000 n Worldwide, agriculture accounts for 70% of all water consumption, compared to 20% for industry and 10% for domestic use. The estimated total volume of water abstractions across Australia was 16 870 GL in 2017–18. Of that, 8% (242,800 GL) runs off as surface water and 2% (49,200 GL) recharges groundwater. Only 5% of all water is fresh water and more than 70% of this is frozen (mostly as ice in Antarctica). Air and water pollution, deforestation, and the depletion of natural resources, to name just a few types of harm. 0000074288 00000 n Learn about wastewater agriculture.
