Analyse multi-échelles des compromis entre services écosystémiques fournis par la flore adventice
2021
Weeds contribute to the provision of various ecosystem services, negative when linked to their harmfulness (disservices) and positive due to the provision of trophic resources (floral resources, seeds) to pollinators and pest natural enemies (services). In this PhD thesis, we analysed how crop management strategies (coherent crop sequences and associated farming practices) implemented by farmers within a small agricultural landscape modulate the weed contribution to (dis)services provision. We also assessed the relative contribution of field cores and field edges (narrow area between the 1st row of the crop and the boundary) to these services. At the annual scale, we show that crop type hig…
New Decision-making Tools for sustainable Weed Control
2021
En 2017, le Conseil fédéral suisse a adopté le pland’action visant à la réduction des risques et à l’utilisation durable des produits phytosanitaires. L’une desmesures de ce plan est «la renonciation complète oupartielle aux herbicides». Or, celle-ci n’est réalisablequ’au travers d’une stratégie de gestion globale desadventices, à l’échelle de la culture et de la rotation. Eneffet, les adventices sont nuisibles pour la culture enplace l’année en cours, mais aussi de manière pluriannuelle par le biais de leur stock semencier. La mise enœuvre de mesures préventives et curatives basées surles principes de la protection intégrée nécessite denouveaux outils d’aide à la décision. Des indicateursd…
Reflexiones sobre la concurrencia de violencia económica en el contexto de familia : impacto y mecanismos para su neutralización
2021
Through this work we carry out a dissertation on the phenomenon of economic violence, as a manifestation of gender violence, in the family context, and, especially, from the perspective of the divorce framework. We will analyze the harmful effects that it produces, the damage that it triggers on the most basic and essential interests of the family, and its use as a control mechanism by the aggressors. In addition to a vision of the different mechanisms that, enshrined in our legal system, serve to distort it.
