Critiquing the ‘Double food production’ narrative

There is little doubt that 9-10 billion people will need to be fed during the next few decades. How we do it is open for debate. The research in our group focusses on the food-biodiversity nexus (Fischer et al 2017), i.e. the challenge of attaining food security for all while conserving global biodiversity. In this field a couple of arguments on how to achieve these goals dominate the discourse. If you want to read more about them then see here, here, here and here for some examples.

Typically, papers addressing these two challenges begin with statements about how agriculture is a major driver of biodiversity loss, something like “Land use change is the biggest threat to biodiversity”, and then the attention turns to food security. Here is where you will more often than not read about the need to increase food production by 70-100 % to feed 9-10 billion people. These two statements are very convenient, and compelling, arguments with which to frame a paper and convince policy-makers. The first statement is uncontroversial. The second statement however uses statistics which are the focus of an excellent critique in the Journal of Rural Studies (Tomlinson 2013).

Tomlinson presents a very good analysis of the origin of this statistic and how it is being used to support academic and policy discourses. I think it is important to note that I have used this statement (with some hesitation) because of its sheer simplicity and the perception that it’s nearly beyond reproach. The paper demonstrates that these data can be used out of context and lack nuance, with the effect of presenting a ‘cut-through’ message for academics and policy-makers. The analysis is far more comprehensive than this so I strongly encourage you to read this paper because it reveals how statistics can be used to influence very important discussions about how we deal with issues of public policy.

What is the role of place-based ecology in conservation biology?

At the Sustainable Landscapes Group we want to improve our understanding of the importance of place-based ecological research in conservation biology. Place-based research in natural and social science is concerned with understanding processes and systems, usually at the ‘local’ scale, sometimes referred to as the ‘landscape’. Many place-based studies are defined by geographic, biophysical, or human constructed boundaries such as administrative units (e.g. local government areas, counties) and many – if not all – are particularly concerned with issues specific to the defined area. However, place-based research can also inform general theory and applications of local knowledge to problems outside the focal place.

We would like to know what type of ecological research ecologists engage in; whether they engage in place-based research; where they do that research, and where they publish their work relative to their careers. We have designed a survey to collect data on this subject and we ask that you help us by clicking here and completing the survey. The survey needs about 10-20 minutes of your time. Please spread the word to all the ecologists you know! We will keep you updated with progress and the results.
