Farm Gate Nutrient Balances In South West Western Australia – An Overview, Rebecca Ovens, David Weaver, Nardia Keipert, Simon Neville, Robert Summers, Martin Clarke
Farm Gate Nutrient Balances In South West Western Australia – An Overview, Rebecca Ovens, David Weaver, Nardia Keipert, Simon Neville, Robert Summers, Martin Clarke
Conference papers and presentations
Farm-gate nutrient budgets can be used to identify the efficiency of nutrient use within and between individual enterprises and catchments, and may be used to represent a component of the risk that particular landuses represent to water quality. Over the past 5 years, more than 400 farm-gate nutrient balance audits have been conducted across a range of catchments and landuses in southwest Western Australia (WA). Values for nutrient use efficiency and surpluses across landuses and catchments are reported. Patterns of nitrogen and phosphorus signatures closely reflect one another across landuses, though nitrogen input, output and surplus values are consistently higher …

Algal blooms in rivers and estuarine waters in south west Western Australia are a symptomatic response to excess nutrient input. Whilst a range of Best Management Practices (BMPs) are available to reduce the causes of phosphorus (P) and nitrogen (N) pollution, most investment has been directed towards symptoms. In order to treat nutrient pollution causes effectively, possible nutrient reductions and the likely adoption costs of a range of BMPs require evaluation. Catchment-scale evaluation of implementation scenarios offers insights not possible through long term on-ground implementation and performance monitoring, and assists community groups and government to respond to pollution issues through …
Traditional Natural Resource Use And Development In Northeast Thailand, Christie Moulton
Traditional Natural Resource Use And Development In Northeast Thailand, Christie Moulton
Senior Honors Projects
This paper explores the effects of development projects on traditional natural resource use in three communities in Northeast Thailand, a region known as Isan. I interviewed villagers in each community and asked them to describe their environmental perceptions, management practices and livelihood strategies. Participants described several subsistence livelihoods that have traditionally been present in Isan. These include rice farming, fishing, community forestry, and wetland use. Residents from the three communities all described various cultural activities, knowledge systems, and religious ceremonies that are closely tied to their local resources. Raising silk worms, making clay pots, and performing rituals for a spirit …

A Comparison Of Agricultural And Urban Influences On Water Quality In South West Wa, Nardia Keipert, David Weaver, Robert Summers, Christian Zammit, Artemis Kitsios, Simon Neville, Martin Clarke
Conference papers and presentations
In Western Australia, a number of coastal rivers and estuaries have suffered from eutrophication since the 1960’s. Often the focus of the threat to water quality in these areas has been agriculture because of its extensive nature and widespread use of highly soluble fertilisers. Over recent years a focus on nutrient inputs, outputs and nutrient balance in a number of projects provides an opportunity to compare the relative nutrient threats from the agricultural and urban sectors, placed in the context of increasing urbanisation and development. These disparate data sets also allow a comparison of nutrient inputs in each sector in …

The Balancing Act, David Weaver
Conference papers and presentations
Nutrient management is as much a global issue as a local one with a balance required between economics and environment, inherent biological limitations and expectations of nutrient use efficiency, and traditional fertiliser practices and actual enterprise nutrient requirements. The concept of nutrient balance depends on context and scale. Nutrient balance can be considered at a global scale, where issues of nutrient stocks, cycles, depletion and transfer of a particular element are important. For a single farm enterprise, nutrient balance might be considered in terms of phosphorus (P) inputs into and outputs from the enterprise. This is commonly known as a …
