Water Management Plan for the Town of Perenjori

The Rural Towns – Liquid Assets (RT–LA) project was established with the aim of integrating salinity, waterlogging and flooding control with development of new water supplies in wheatbelt towns, and where possible, finding ways of putting the excess water to commercial use. Following the identification of effective integrated water management strategies, these have been applied to the 15 Shires participating in the DAFWA led RT–LA project. This report summarises the outcomes from all scientific investigations undertaken for Perenjori. In addition it presents the water management options, a preliminary analysis of those options and the priority recommended ones. Due to the decline in rainfall over the past 10 years, Perenjori groundwater levels have shown a declining trend below the townsite since 2000, when groundwater monitoring by DAFWA in the townsite commenced. Hydrogeological studies identified groundwater pumping was not an effective solution for Perenjori to control watertable levels in the high salinity risk areas of the townsite. The studies demonstrated that only limited volumes of groundwater could be abstracted by pumping because the drawdown affects would be constrained by the geological properties. It is concluded that salinity control or water production from under the townsite via groundwater pumping is not a technically viable option. Instead, the RT–LA project has focused on surface water management options that will enable new water supplies to be developed which will also alleviate salinity, watertable, waterlogging and flooding problems. An integrated scheme such as this will provide cost effective solutions to the annual problem of irrigation water shortages. Over time, the proposed surface water diversion and harvesting schemes will reduce salinity risk by diverting and utilising runoff water which would otherwise have contributed to local recharge. Option 1, construction of a new 30ML dam in the paddock east of town belonging to Mr Jim Gilmour, is recommended as the first priority action. Along with the other options outlined in this Water Management Plan, Option 1 offers a combination of surface water engineering solutions to capture the town’s runoff and provide up to an additional 31 ML/yr, or 155 per cent of the total existing demand

Merredin townsite groundwater pumping and desalination pilot project

Townsite salinity affects more than 40 towns in the WA wheatbelt. Waterlogging and salinity are responsible for damamge to townsite infrastructure. Through groundwater pumping and desalination, the State Salinity Council (now the Natural Resource Management Council) granted Merredin the the chance to prevent further damage to the townsite by funding this project

Political strategies of external support for democratization

Political strategies of external support to democratization are contrasted and critically examined in respect of the United States and European Union. The analysis begins by defining its terms of reference and addresses the question of what it means to have a strategy. The account briefly notes the goals lying behind democratization support and their relationship with the wider foreign policy process, before considering what a successful strategy would look like and how that relates to the selection of candidates. The literature's attempts to identify strategy and its recommendations for better strategies are compared and assessed. Overall, the article argues that the question of political strategies of external support for democratization raises several distinct but related issues including the who?, what?, why?, and how? On one level, strategic choices can be expected to echo the comparative advantage of the "supporter." On a different level, the strategies cannot be divorced from the larger foreign policy framework. While it is correct to say that any sound strategy for support should be grounded in a theoretical understanding of democratization, the literature on strategies reveals something even more fundamental: divergent views about the nature of politics itself. The recommendations there certainly pinpoint weaknesses in the actual strategies of the United States and Europe but they have their own limitations too. In particular, in a world of increasing multi-level governance strategies for supporting democratization should go beyond preoccupation with just an "outside-in" approach

Prevalence and architecture of de novo mutations in developmental disorders.

The genomes of individuals with severe, undiagnosed developmental disorders are enriched in damaging de novo mutations (DNMs) in developmentally important genes. Here we have sequenced the exomes of 4,293 families containing individuals with developmental disorders, and meta-analysed these data with data from another 3,287 individuals with similar disorders. We show that the most important factors influencing the diagnostic yield of DNMs are the sex of the affected individual, the relatedness of their parents, whether close relatives are affected and the parental ages. We identified 94 genes enriched in damaging DNMs, including 14 that previously lacked compelling evidence of involvement in developmental disorders. We have also characterized the phenotypic diversity among these disorders. We estimate that 42% of our cohort carry pathogenic DNMs in coding sequences; approximately half of these DNMs disrupt gene function and the remainder result in altered protein function. We estimate that developmental disorders caused by DNMs have an average prevalence of 1 in 213 to 1 in 448 births, depending on parental age. Given current global demographics, this equates to almost 400,000 children born per year
