SHEPPARTON IRRIGATION REGION (AGRICULTURAL FLOODPLAINS) LAND AND WATER MANAGEMENT PLAN 2016-2020 THE FINAL UPDATE OF THE 1990-2020 PLAN GROWING THE NATURAL ADVANTAGE - PART A
FOREWORD For 25 years community and agencies have worked together to tackle issues that threaten the natural resources underpinning agricultural production across the Shepparton Irrigation Region (SIR). Considerable progress has been made over this time. Implementing, reviewing and renewing our SIR Land and Water Management Plan have been essential steps. This process has ensured we set actions and targets, report on progress and reflect regional priorities. We are now implementing the last 5 years of a 30-year plan, a significant achievement for catchment management. Our success is built on strong and enduring partnerships, an approach that is reflected in the development of this plan, the fifth and final iteration. A community led Taskforce was established under the guidance of the Sustainable Irrigation Program Advisory Group to look at the previous plan and identify emerging issues and actions to make the SIR a world-leader in the sustainable production of milk, fruit, vegetables, grains and meat. The Taskforce directed a way forward for this sustainable production that also protects and enhances our natural resources. The Taskforce recognised the need to advocate for increased funding for the continuation of drainage, whole farm planning, and biodiversity and revegetation programs across the SIR. Community see the continued improvement in on-farm water use efficiency through the Farm Water Program as critical for the future prosperity of the region. Community also wanted more emphasis placed on projects that support water availability and farm viability, waste management, water and land stewardship and renewable energy use. The Taskforce revised the structure for overseeing the plan implementation, forming the Shepparton Irrigation Region People and Planning Integration Committee (SIRPPIC). This Committee builds on existing partnerships and encourages innovation and community leadership development. Together we can achieve effective land and water management and a thriving SIR.

Residents, tourists, kangaroos, cows and others enjoy a great climate in an iconic Australian setting: agricultural woodland landscapes between vast areas of riverine forests and wetlands, including the world’s largest river red gum forest, the Ramsar-listed Barmah wetlands. The SIR has significant brand strengths in quality produce, integrated governance, and cutting-edge irrigated food production and food processing technologies. The region also enjoys an international reputation for environmental leadership. Visitors from all over the globe visit the region to better understand how the state-of-the-art irrigation delivery system and farm technologies are integrated with management of natural resources and how genuine partnerships are fostered between government, industry and the community. Maintaining this reputation and overcoming challenges falls within the domain of the SIRLWMP, as described in the next chapter. 7
