Evidentiary

Evidentiary Informing, empowering and engaging through evidence We work in environmental research.

We systematically search for evidence relevant to a topic and summarise or synthesise this to assist in decision making. Often this evidence is from around the world and may be from peer reviewed journals, Master or PhD student theses, conference papers, government reports, unpublished literature or expert interviews. We use evidence based approaches to search for this information and distil the

findings into a comprehensive, user friendly report with clear findings and recommendations to act upon. It’s likely that most issues facing natural resource workers today have been encountered and described by other workers all over this country and the world. Instead of re-inventing the wheel, why not use existing evidence to understand what approaches have been successful and why and which have not and why? Using a large number of evidence sources of high quality to inform natural resource decision making can often lead to better decisions, lower risk and more effective outcomes. This is because comprehensive, better quality information builds a more complete picture of our understanding of an issue. It’s easier to make a good decision about something when you are well informed and understand the many contextual issues at play. Consequently, using evidence to guide decision making is also good risk management.

Irrigation - can it be both water and energy efficient? While the water efficiency of irrigation systems has improved significantly, water efficient irrigation systems often consume a lot more energy. Evidentiary, along with NSW Farmers and Jason Alexandra of Alexandra & Associates undertook a scoping study that set out to identify critical issues and opportunities for promoting the adoption of energy efficiency in irrigation. Read a summary of the review findings here: https://evidentiary101.wordpress.com/2015/03/06/irrigation-can-it-be-both-water-and-energy-efficient/

Over recent decades there has been major public and industry funded research and development in irrigation water efficiency, partly driven by the millennium drought.While most irrigators that have ...

What's your risk profile - if you were one of the three little pigs, would you build your house out of straw, sticks or bricks? It's easy in retrospect to say 'bricks of course!' but the foresight required to consider the evidence around a project or intervention is not always present. Decision making and policy formation in environmental management is no exception, as we discuss in the article below: https://evidentiary101.wordpress.com/2015/02/17/the-lazy-mind-straw-sticks-and-bricks-whats-your-risk-profile/

Are you a system 1 or a system 2 thinker?
In his international best seller 'Thinking fast and slow', Daniel Kahneman provides a fascinating insight into how we think and make decisions. Could it be that our brains' preference for system 1 thinking (suppression of doubt, confirmation of existing beliefs, intuitive judgement and impulsive likes and dislikes) can explain the resistance to actually undertaking evidence based decision making?

What do wind farms and Miss America have in common? Find out in our final edition of this series which considers a case study from the health sector. The case study examines wind farms and human health and highlights that correlation between two variables does not necessarily imply that one causes the other. https://evidentiary101.wordpress.com/2015/01/13/correlation-does-not-imply-causation-wind-farms-and-human-health/

What's the evidence that smaller class sizes are better for learning? given the substantial funds invested in decreasing class sizes over the years, the answer to this question is an important one. Click on the link below for a summary of a recent systematic review on the topic, which had some novel findings. ttp://bit.ly/1DydyZZ

We investigate microfinance in Part 2 of our series of case studies which investigate the utility of evidence in policy and practice. A popular intervention to alleviate poverty in the international development sector, what is the evidence that microfinance actually works?

In part two of this series, we’ll examine a case study from international development which highlights that popular interventions may not be the most effective. By undertaking evidence based review...

Proponents of evidence based practice often laud the many benefits of the use of evidence, but what exactly are they? Can using evidence really make a difference to policy formation and practice outcomes? We investigated many case studies where evidence has been used in different fields.

The case study below examines the effectiveness of a popular criminal prevention policy called 'Scared Straight.' Despite being a key crime prevention program in numerous states of the USA and implemented in Australia, Germany and Norway - does it really deter at risk youth from a life of crime? The results are sure to surprise!

Does evidence influence practitioner management decisions in the environmental sector?A recent study undertaken by Walsh et al., 2014 looked at the influence of providing summarised scientific evidence on interventions to reduce bird predation to conservation managers around the world. Over 90% of the 112 participants indicated that they would change at least one intervention in light of the new evidence.Click on this link http://bit.ly/1vlohT0 for a summary of the study.

A key reason given to justify the time and funding invested into scientific research is that the findings of the research will benefit society. In the environmental sector, one of the main vehicles...
