Abstract: In this thesis, composed of three essays, we use viability theory (VT) to address soil restoration problems subject to some environmental and socio-economic constraints such as reaching an environmentally acceptable quality of the soil and ensuring acceptable incomes for the farmers.

Our objective is to study these problems in different frameworks that take into account some of the most important factors that influence them such as uncertainties (climatic uncertainties) and farm practices (parcellation) in order to gain insight into how the agronomic systems react to these factors and to what extent they are sensitive to them and thus have a more precise idea of the strategies that can be put in place to achieve the objectives of soil restoration and preservation.

More specifically, we use viability theory to study the problem of soil restoration of a parcel subject to climatic uncertainty (hurricanes) as well as the effects of parceling in a deterministic context. Our empirical study concerns the archipelago of Guadeloupe, located in the French West Indies.
