This publication brings together the findings from the National River Contaminants Program and includes: * Understanding Salinity thresholds in freshwater biodiversity * Nutrients as contaminants * Managing algal blooms in Australia

This report arises from a scoping brief presented to the author on 19th May 1995. The brief r required an overview of the R&D Program currently being conducted under the management of Dr Nick Schofield of the Land & Water Resources R&D Corporation and jointly established by that body, the Cotton R&D Corporation and the Murray Darling Basin Commission. The R&D program is entitled -Minimising the Impact of Pesticides on the Riverine Environment Using the Cotton Industry as a Model- .

This review is part of the standard procedures of the Land & Water Resources Research and Development Corporation (LWRRDC) to ensure that Research and Development (R&D) programs are accountable and responsive to the needs of investors, providers and users. The National Climate Variability R&D Program (NCVP) has been operational for five years, through two lots of three year phases, which al lows an effective assessment of its achievements. In addition, the review is timely in that it can contribute to the planning of a possible third phase of the program.

Native pastures are a valuable resource for woolgrowers. Maintaining the perennial components in a native pasture can contribute to improved tensile strength of wool and assist in the control of acidity and dryland salinity. * Strategic grazing and the careful use of fertiliser can significantly improve the profitability of these pasture systems. High rates of fertiliser or inappropriate grazing can reduce the contribution from valuable native grasses. * Woolgrowers need to be aware of their legal responsibilities when modifying management on their native pastures and grasslands

The National Program for Sustainable Irrigation is a collaboration between 16 investment partners including irrigator groups, water authorities, state government agencies, Research and Development Corporations and the Australian Government. This is their strategic plan for the period indicated which provides an overview of the vision, mission, objectives and values of NPSI.

An occasional magazine from Land & Water Australia's Native Vegetation Program that is full of new ways of thinking about, planning and managing the Australian Bush. This issue

Knowledge is one of our most valuable and intangible assets. A research project in the cotton and grains industries has been asking the question: how is irrigation information accessed and knowledge managed to make better decisionsΓ

Implications for local provenance seed selection and landscape restoration

The rivers, floodplains, wetlands and estuaries of northern Australia are key resources. In this issue, Rip Rap looks at new research projects funded by Land & Water Australia that are focused on the 'Top End' of Australia, its rivers, people
