Mitigation cost of greenhouse gas emissions from fertilization in agriculture
Description
In this thesis, we assess the mitigation cost of greenhouse gas (GHG) from fertilization which represents 38% and 44% of agricultural GHG emissions in Europe and in France. This assessment is conducted for two key measures in climate mitigation which are the implementation of legumes crops and the reduction of fertilization per hectare. The abatement potential of legume crops is computed by simulating their increase in French croplands and also by a switch of crop rotations on several years (up to 6 years) in five European regions. Results show that significant mitigation amounts can be obtained by increasing farms revenues. The role of risk aversion is studied through the reduction of fertilisation per hectare. We analytically shows the conditions leading to nitrogen over-applications on crops which allows farmers to minimize their risk of loss on crop yields. The simulations lead on risk averse farmers show that an insurance covering yield variability could be foreseen as an interesting tool to mitigate emissions. (author)
Abstract (French)
L'objectif de cette these est d'estimer le cout de mesures d'attenuation des emissions de gaz a effet de serre (GES) liee a la fertilisation des cultures qui represente en Europe et en France respectivement 38% et 44% des emissions de GES de l'agriculture. L'etude du cout et du potentiel d'abattement est effectuee sur deux mesures cles dans l'attenuation des emissions a savoir la mise en place de plantes fixatrices d'azote (i.e. legumineuses) et la reduction de la fertilisation par hectare. Le potentiel d'attenuation des legumineuses est etudie en simulant leur augmentation dans les assolements agricoles francais et dans un deuxieme temps a l'echelle de rotations de cultures pouvant durer jusqu'a six ans dans cinq regions europeennes. Les resultats obtenus revelent que des reductions importantes d'emissions sont possibles, tout en augmentant le profit des agriculteurs. Le role de l'aversion pour le risque est aussi etudie concernant la reduction de la fertilisation des cultures par hectare. Nous montrons analytiquement les conditions conduisant a une sur-application d'engrais par hectare permettant aux agriculteurs averses au risque de minimiser le risque de perte de rendement. Les simulations numeriques effectuees specifiquement sur les agriculteurs averses au risque demontrent qu'une assurance d'attenuation des emissions peut potentiellement declencher des reductions importantes d'emissions de gaz a effet de serre.
