Community-based approaches have been a key feature of regional salinity management programs
Community-based approaches have been pivotal to regional salinity management programs in Australia. This is in response to various government initiatives, such as the National Landcare Program (1989), the Natural Heritage Trust (1997), and the National Action Plan for Salinity and Water Quality (2000). These community-driven initiatives have played a crucial role in raising awareness, educating the public, and facilitating the sharing of local knowledge and information, which is essential for developing effective management plans.
One notable example of a community-based program is Saltwatch, established in Victoria in 1987. Saltwatch is a community- and school-based initiative that involves students, teachers, and community members in monitoring salinity levels in local waterways. Participants collect water samples, conduct salinity tests, and record data, fostering partnerships between government agencies and the community. While Saltwatch focuses on education and data collection, it may not be directly linked to implementing salinity management strategies.
The success of community-based approaches lies in their ability to provide a social platform necessary for the successful adoption of salinity management practices. These approaches empower communities to address salinity issues by developing skills and building capacity. However, one challenge faced by community-driven initiatives is the lack of scientific skills and detailed knowledge required to devise viable technical and economic salinity management solutions.
Furthermore, it is important to acknowledge that community-based approaches may inadvertently reinforce existing power structures, potentially marginalizing already disadvantaged groups in decision-making processes related to salinity management. Nevertheless, the involvement of government agencies and the community demonstrates a shared concern about salinity's impact on land and water resources' value. This concern is particularly acute regarding irrigation-induced salinity in the Murray-Darling Basin and dryland salinity associated with shallow groundwater, especially in Western Australia.
In conclusion, community-based approaches have been instrumental in regional salinity management programs in Australia. They have facilitated awareness, education, and local knowledge sharing while empowering communities to address salinity issues. However, addressing the lack of scientific and technical expertise in these initiatives and ensuring inclusive decision-making processes are essential steps for more effective salinity management in the future.

The government is raising awareness and educating communities about dryland salinity
The Australian government is taking several measures to address the issue of salinity, particularly dryland salinity, which is a significant environmental concern in the country. One key aspect of their strategy is raising awareness and educating communities about this issue.
Dryland salinity is a major cause for land degradation in Australia, particularly in Western Australia, affecting over 2 million hectares of broadacre farmland. It is caused by a combination of factors, including irrigation, shallow groundwater, and land clearing for agriculture, which replaces deep-rooted native vegetation with shallow-rooted crops. This change in vegetation allows for more groundwater recharge, raising the water table and bringing salts closer to the surface, resulting in salt concentration through evaporation.
To address this, the government has initiated various programs and plans, such as the National Action Plan for Salinity and Water Quality (NAPSWQ), which aims to prevent, stabilize, and reverse salinity trends, improve water quality, and secure reliable water allocations. The NAPSWQ recognizes the importance of community involvement and aims to build community capacity. Additionally, the Natural Heritage Trust (NHT) has the overarching objectives of biodiversity conservation, sustainable use of natural resources, community capacity building, and institutional change.
At the state level, the Western Australian government has also implemented significant salinity research and management programs. For instance, the Water Resource Recovery Program focuses on scientific investigation, planning, and implementation to reduce salinity in key water resource recovery catchment (WRRC) areas. The Salinity Action Plan, initiated in 1996, identified rivers that required active intervention to prevent deterioration beyond recovery from salinization.
Furthermore, community-based approaches have been crucial in salinity management. Saltwatch, established in Victoria in 1987, is a community- and school-based program that involves students, teachers, and community members in monitoring salinity levels in Australian waterways. This program provides an educational platform and fosters partnerships between government agencies and the community. However, it is important to note that scientific skills and detailed knowledge are often lacking in developing viable technical and economic salinity management options.
The government's initiatives and community involvement are essential steps towards managing and mitigating the impacts of dryland salinity in Australia. By raising awareness, educating communities, and implementing various programs, Australia is actively working towards preserving its natural resources and addressing the challenges posed by salinity.

The National Action Plan for Salinity and Water Quality was introduced in 2000
In November 2000, the Australian government introduced the National Action Plan for Salinity and Water Quality (NAP) to address the growing concerns of salinity in the country. The NAP was a joint initiative between the Australian Government and State and Territory Governments, with a total expenditure of $1.4 billion over seven years. The goal of the NAP was to motivate and enable regional communities to take coordinated and targeted action to prevent, stabilize, and reverse the trends of dryland salinity, which was affecting the sustainability of production, conservation of biodiversity, and the viability of infrastructure.
The NAP focused on 21 priority regions identified by the National Dryland Salinity Program as being at the highest risk of dryland salinity. Most of these regions were in Eastern Australia, with a significant number of areas in New South Wales and Victoria heavily affected by dryland salinity. The projects were carried out by regional Natural Resource Management (NRM) organisations, with funding from both state and federal governments. One notable project involved the plantation of 100,000 trees over two years in the Land Macquarie Landcare area, with a 50% survival rate.
The NAP also aimed to improve water quality and secure reliable allocations for human uses, industry, and the environment. This included addressing the issues of irrigation-induced salinity in the Murray-Darling Basin and dry-land salinity associated with shallow groundwater, particularly in Western Australia. The program recognised the need for coordinated action and the involvement of regional communities in tackling salinity issues.
While the NAP was successful enough to be followed by the National Landcare Program, there were areas that needed improvement. For example, most of the budget went towards paying farmers incentives to adopt new desalination treatments, which was considered inefficient. Additionally, the rollout of funding was slower than anticipated due to the nature of the program and the distribution of funds to various regional groups.
Overall, despite some weaknesses, the NAP represented a significant effort by the Australian government to address the pressing issue of salinity and its impact on the environment, agriculture, and water resources.
