Comparing Apples and Oranges

In real-life situations, it is far more common for decisions to be based on a comparison between things that can’t be judged on the same standards. Whether you’re choosing a dish or a house or an area to prioritise for conservation you need to weigh up completely different things like cost, size, feasibility, acceptability, and desirability.

Those three examples of decisions differ in terms of complexity – you’d need specific expert knowledge and/or the involvement of other key stakeholders to choose conservation prioritisation areas, but probably not to pick a dish. The bottom line is they all require evaluating different alternatives to achieve the desired goal. This is the essence of multi-criteria decision analysis (MCDA). In MCDA the pros and cons of different alternatives are assessed against a number of diverse, yet clearly defined, criteria. Interestingly, the criteria can be expressed in different units, including monetary, biophysical, or simply qualitative terms. Continue reading

New Studies Aim to Boost Social Science Methods in Conservation Research

Below is a press release about the Methods Special Feature ‘Qualitative Methods for Eliciting Judgements for Decision Making‘ taken from the University of Exeter.

Scientists have produced a series of papers designed to improve research on conservation and the environment.

A group of researchers have contributed to a Special Feature of the journal Methods in Ecology and Evolution to examine commonly used social science techniques and provide a checklist for scientists to follow.

Traditional conservation biology has been dominated by quantitative data (measured in numbers) but today it frequently relies on qualitative methods such as interviews and focus group discussions. The aim of the special issue is to help researchers decide which techniques are most appropriate for their study, and improve the “methodological rigour” of these techniques. Continue reading
