The concept of biodiversity loss is absolutely integral to conservation, and I have never met anyone who has seriously challenged the idea that too many species are going extinct, nor that their extinction is a result of human pressures. So, what do we make of multiple studies telling us that we shouldn’t be focusing so much on biodiversity loss? These studies say that, on average in samples across the world, roughly equal numbers of sites are increasing in species richness and decreasing.

Maria Dornelas is the ecologist, from the University of Lisbon and the University of St Andrews, at the centre of this research and she joins me to elaborate. It should be mentioned right at the start that Maria is not suggesting that biodiversity loss is not a problem, but she explains why she thinks we are doing conservation a disservice by focusing on it the way we do. Maria emphasized the importance of nuance in conversations about conservation, and this discussion is an illustration of the importance of avoiding too much generalization and simplification.

Although we all have our problems, war is usually not among them. But if you do live in a war-torn country like Ukraine, war is everyones’s problem. And yet, in Ukraine at least, somehow life goes on including activities like conservation of the environment. The question is how, and why, given the many, more urgent, priorities.

Marine Elbakidze is an Associate Professor at Lviv University, who focuses on sustainable landscape management, forest governance, and the social-ecological systems approach to environmental conservation. A year and a half ago she left a comfortable job in Sweden to return to Ukraine and practice her profession in her home country despite its ongoing war.

Conservation competes with a variety of other societal priorities and interests for funding and for attention. As a result, conservation projects, programmes and even broader concepts are frequently “packaged” in ways that prioritize grabbing attention. But promoting or marketing conservation initiatives in this way carries certain risks. Among them is the risk of being short-lived and without a real basis in the substance of the actual initiative – in other words a fad. Another is the risk of losing what has already been learned, when initiatives are “re-packaged” under a new buzzword.

Kent Redford is the principal at Archipelago Consulting, and previously Director of the Wildlife Conservation Society Institute in New York. In 2013 Kent published a paper in the journal, Conservation Biology to flag his concerns about conservation fads. I called him up to revisit this topic, because it relates quite closely to my increasing concern about conservation buzzwords.
