Enhancing systematic literature review adapting 'double diamond approach'.

Current literature review frameworks often lack quantification of literature volume, guidance on keyword inclusion, confidence in identifying knowledge gaps, and the formulation of research questions, which can lead to potential bias in research. This undermines the validity and reliability of reviews. In this paper, we aim to enhance the systematic literature review (SLR) methods-starting with a review of review literature followed by a review of empirical literature-to address these challenges.

Geographic information system based manure application plan.

A geographic information system (GIS) based manure application plan has been developed for the site-specific application of animal waste to agricultural fields in the Westbrook sub-catchment of the Murray-Darling Basin, south-east Queensland, Australia. Sites suitable for animal waste application were identified using a GIS based weighted linear combination (WLC) model. The degree of land suitability for animal waste application was determined using a range of social, economic, environmental, and agricultural factors.
