Research topics in crop diversification at the landscape level
No full textCrop diversification has many benefits both at the cropping system and the food system levels and has
been addressed in agricultural research (Hufnagel et al., 2020). Landscape design and management in
agricultural regions can support crop diversification by building bridges with scientific domains like
ecology and geography (Benoit et al., 2012). Though, little is known on how the research community has
addressed crop diversification from a landscape perspective. In this paper we investigated a
bibliographic corpus retrieved from the Scopus database papers coupling crop diversification and
landscape (in title, abstract and keywords), retrieving 461 papers for the period 1990 to 2020. The
corpus was analysed using the CorText platform (e.g., Ruiz-Martinez et al., 2015). First, natural language
processing was used to extract multi-terms from title, abstract and keywords. Then, we mined the
temporal dynamics and co-occurrence of the 100 most frequent terms. Our findings showed that
species richness emerges as the main topic in this corpus and that natural enemies, crop types and
natural control increased in importance. In the last years, genetic diversity, climate change and
agricultural production also gained attention. On the contrary, land use and some of the terms related
to diversity (landscape, plant and farmland) were marginal or decreasing. By analysing the terms cooccurrence on the three decades, we observed that the papers addressing crop varieties and
agroforestry system split into two streams: one about agricultural production in relation to climate
change and the other about farm size and land use. Instead, the functional diversity and field margin
disappeared from recent literature. Land use patterns and landscape diversity converged mainly on
studies about biological pest control. Altogether, the corpus highlighted that the spatial configuration
lost importance when addressing crop diversification. In addition, the species diversity gained attention
finally catching a large part of the literature in the corpus. From a landscape approach perspective, we
might point out the apparent lack of a major topic: the involvement of local communities and
stakeholders. Our simple and rapid text mining approach yielded early evidence of knowledge gaps
about the landscape level in crop diversification literature. The expected contribution of approaching
the crop diversification at the landscape level would be to provide a relevant framework for the
characterisation of the baseline system to be diversified. In particular, the landscape agronomy
perspective stressed the need to define the scale and target area for crop diversification consistently
with (natural and cultivated) species diversity embedded in a local socio-technical system

No full textNapoleon Schmidt is Dead: A Hystopian Novel
No full textThis dissertation consists of two sections: a novel, Napoleon Schmidt is Dead, and a critical commentary. The novel is set against the backdrop of East Berlin in the 1980s and tells the story of fifteen-year-old Anna, who starts to question the world she lives in. Strange notes and potatoes form a mysterious trail that Anna hopes will lead her to the truth. The price she pays is her freedom. Although the historical context is real, the novel draws on tropes of dystopian fiction to engender an atmosphere of paranoia. The novel is aimed at a teen audience and is a story of female friendship, rebellion and coming-of-age at a time when the status quo demands uniformity and punishes individuality. It articulates the sense of powerlessness experienced by teenagers within family structures, which is amplified through the restrictions of growing up under an oppressive regime.
The critical commentary is divided into five sections, each of which takes as its focus a specific author of dystopian fiction, tracing the ways in which these writers respond to each other’s work. The commentary further investigates the origins and evolution of dystopian fiction, and considers its generic next-of-kin in that context.
The original contribution to knowledge lies in the development of the ‘Feindt Principle’, a proposal of a new sub-genre, ‘hystopia’, a new piece of hystopian fiction and the induction of Anna Burns’ novel Milkman (2018) into the canon of hystopian fiction
Evaluation of the sustainability of minor crops in Normandy region, France
No full textCrop production in Normandy is highly specialized and based on a few crops (e.g. soft wheat, flax,
rapeseed, sugar beet,..) which raises the question of agricultural sustainability. This issue is of great concerns when we consider protein autonomy issue at French and European levels. Thus, the development of alternative crops could help in the diversification of crop rotations andcontribute in the increase of the proportion of plant-based proteins. Because of their protein content, grain legumes, cereals and oilseeds would offer benefits for human health (Becerra-Tomás et al., 2017), the environment (Springmann et al., 2016), and global food security (Erb et al., 2016). Increasing the proportion of grain legumes in cultivated areas could reduce the current protein deficit and contribute to sustainable farming systems.
PROVEG project aims to evaluate the potential of protein-rich crops that are absent or poorly established in Normandy region. The consortium includes two reserach partners (UniLaSalle and Normandy University) and three agricultural stakeholders (Natup, CerFrance and lycée agricole Yvetot) that
represent key player in the local and regional scale. In this context, the project will focus on the potential of five minor crops including four grain legumes (pea, faba bean, lupin, lentil), and a pseudo-cereal crop (quinoa) will be evaluated in the pedoclimatic context of Normandy. The challenges consist in the
identification of crop management adapted to these five crops based on a systemic approach to optimize cropping practices and maximize the potential benefits of these crops. This approach involves the consideration of climatic conditions, soil biological state, crop vulnerability and socio-economic
obstacles related to their introduction and sustainability in Normandy region.
The expected findings will include i) the identification of suitable crop managements and the causes of yield losses for production and, ii) the assessment of crops vulnerability under climate change by taking into account the nature, the magnitude and the rate of climate change as well as the agro-ecological
and socio-economic aspects of crops. The results of the project will allow us to make propositions to farmers and agricultural advisers to support the introduction of protein crops during transitional pathways on a broader spectrum of farms.
Therefore, the findings will contribute to the territorial dynamic by offering to decision-makers information about potential crop suitability and geographical distributions to make strategic investments in infrastructure, and market protein-rich crops produced in Normandy area
