Book excerpt: In recent years water quality issues have become apparent in coastal areas of the Lower Burdekin. Longer term, steadily rising groundwater salinity levels have been reported in bores in the Airdmillan Road area of the North Burdekin Water Board (NBWB). The Airdmillan Road area is close to the coast and the environment surrounding the area is a complex mix of hydrological features. Groundwater and surface water are used for irrigation of sugarcane. Lack of pumping volumes is a severe impediment to allow both whole-of scheme and on-farm water management. The current level of available data on groundwater & surface water pumping and crop water requirements is not sufficient to show how each of these factors contribute to the overall hydrology and salinity in the area. This report briefly describes the extent and cause of the problem to help support development of a management plan for sustainable groundwater resources in the area. Despite the lack of data it is believed that the main cause of increasing groundwater salinity is the volume of water extracted from bores in the area resulting in upwelling / upconig (i.e. movement of saline water from deeper in the aquifer to shallower depths). A fine balance between pump location, pumping volume, and pump depth must exist to ensure water quality is not degraded. We strongly recommend that further work be undertaken to measure the amount of groundwater pumped and surface water applied for irrigation. This work could then be used to identify the major drivers of water quality deterioration in the area and ultimately support development of a regional management plan built on more robust knowledge of the local hydrology.

Book excerpt: As part of the National Action Plan for Salinity and Water Quality project Intitiation of a Lower Burdekin Water Quality and Salinity Management Program, CSIRO Mathematical and Information Sciences were engaged to analyse the groundwater database data maintained by the Queensland Government Department of Natural Resources and Mines (QNRM) for trends in groundwater salinity and nitrate concentration. This report details the analyses performed and reports some of the overall trends from the Lower Burdekin groundwater database data. This work looks at whether salinity and nitrate levels are changing and the rate at which they are rising or falling. Electrical conductivity (EC) was used as a surrogate for salinity" --P. 5.

This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Australia is currently the second largest exporter of raw sugar after Brazil, and one of the world's top five sugar exporters. This book tells the story of how the Australian cane sugar industry grew into a major global supplier of sugar, how it became a significant innovator in the technology associated with the growing and harvesting of sugar cane as well as the production and transport of sugar. It describes the spread of sugar cane growing along the north-eastern coast of Australia during the late nineteenth century, and how subsequent twentieth-century expansions were tightly regulated in order to avoid overproduction. It examines changes in agricultural techniques, efforts to combat pests and diseases, breeding new cane varieties and the significance of improvements in the sugar milling and refining processes. Special attention is also devoted to documenting how sugar production changed the landscape of north-eastern coastal Australia. Topics considered include deforestation, soil erosion, loss of wetlands associated with drainage improvements, the introduction of fauna to control insect pests affecting the crops of sugar cane and mining the coral of the Great Barrier Reef to produce agricultural lime. It is the first comprehensive account of the history of the Australian cane sugar industry.
