Eating meat leads to several environmental threats, hence reducing one’s consumption can be a direct way to avoid environmental degradation. While sustainability scientists know about the environmental degradation due to meat consumption, many of them still choose to eat meat. It is questionable whether a broader societal transformation towards sustainable consumption is likely if people with the necessary knowledge and values already struggle and fail to implement a sustainable behavior. How can they expect others to change if they do not change themselves? This paper addresses the knowledge-action gap that is prevalent among sustainability scientists regarding their meat consumption and how they deal with it. Qualitative semi-structured interviews and thematic content analysis are applied to analyze the main internal barriers to pro environmental behavior sustainability scientists face as well as what narratives and rationalizations they use to overcome the dissonance between their knowledge and actions. The internal barriers they demonstrated were emotional non-involvement and a perceived lack of power of the individual. The strategies used to overcome the dissonance were conscious consumption narratives and rationalizing the value of meat consumption, specifically its perceived sustainable dimensions. This paper also highlights that sustainability scientists do feel responsible to lead by example in the context of societal transformation, but do not always follow through with behavior change. This study concludes it is necessary that sustainability scientists do so more consequently to embrace their role as trendsetters and change agents for a sustainable transformation.

In Senegal, West Africa, soils are a vital resource for livelihoods and food security in smallholder farming communities. Low nitrogen (N) soils pose obvious challenges for crop production but may also, counterintuitively, promote the abundance of agricultural pests like the Senegalese locust, Oedaleus senegalensis. In this study I investigated how the abundance of locusts and grasshoppers are impacted by soil fertility through plant nutrients and how these variables change across land use types. We worked in two rural farming villages in the Kaffrine region of Senegal. Overall, there was little variation in soil properties and an agricultural landscape low in soil organic matter (SOM) and inorganic soil nitrogen. I corroborated that SOM is a significant driver of soil inorganic N, which had a positive relationship to plant N content. Of the management practices we surveyed, fallowing fields was important for soil nutrient restoration and years spent fallow was significantly correlated to inorganic soil N and SOM. O. senegalensis was least abundant in groundnut areas where plant N was highest. Additionally, I found a significant negative correlation between O. senegalensis abundance and plant N, suggesting that plant nutrients are an important driver of their populations. Grasshoppers, excluding O. senegalensis, were more numerous in grazing areas and fallow areas, perhaps due to a higher diversity of ecological niches and host plants. These results connect land use, soil, and vegetation to herbivores and suggest that improving soil fertility could be used as an alternative to pesticides to keep locusts at bay and improve crop yields.

Globally we are struggling to match the need for development with the available resources. Kate Raworth’s (2012) developed the idea of a “safe and just space” as a balance between the planetary boundary approach and ensuring a level of basic needs satisfaction for everyone. O’Neill et al. (2018) argue that countries are currently not able to provide their populations with basic needs without concurrently exceeding planetary boundary measures. While attempts have been made to get people to change their habits through moral self-sacrifice, this has not been successful. Kate Soper (2008) argues that a change towards sustainability will only be possible if an alternative to high consumption is offered, without trade-offs in well-being. Technological improvements are often thought to end up providing solutions to the problem of overconsumption, but as Jackson (2005) shows convincingly, this is highly unlikely due to the overwhelming scale of changes required.

‘Alternative hedonism’ (Soper 2008) is a philosophical approach that has been proposed to solve this dilemma. By changing what humanity pursues to be less focused on consumption and more linked to community interaction and living healthy, fulfilling lives, we would simultaneously reduce stress on the globally limited resources and sinks. By developing and understanding satiation points – the point beyond which well-being no longer increases because of increased consumption - affluence that wastes resources without improving well-being could be reduced. This paper explores how ‘alternative hedonism’ and the development of ‘satiation points’ could be helpful in getting humanity closer to the ‘safe and just space’. The paper concludes with a discussion of some of the challenges that taking up of ‘alternative hedonism’ would entail.
