Land landslides are processes of degradation of damaging agricultural land and difficult to anticipate. In general, the degradation of agricultural lands by landslides involves changing the use category of the affected area, always from one upper to the lower one; most of the time goes to set-aside, ie to unproductive land. The production of landslides determines, first of all, the change of the slope configuration on which, the conditions of agricultural exploitation are worsening. The smoothing and landscaping of sloping lands involve high costs, the use of special equipment and the adoption of solutions - in some cases - of great technical difficulty. The natural conditions in Iasi county are favorable to slope processes. Exploitation of agricultural land without respecting soil fertility conservation requirements has favored the intensification of the soil erosion process and the reactivation of some landslides. All of this has negative repercussions on the agro-production potential of agricultural lands on the slopes. The paper presents the evolution of agricultural trains affected by landslides after 1990. The analysis was carried out on the basis of the data provided by the Office for Pedological and Agrochemical Studies of Iasi, the National Agency for Land Improvement, North Moldova subsidiary and the National Institute for Research and Development for Land Improvement, Iasi branch. Case studies are also presented for the situation in representative communal territories. The analysis was carried out on the basis of the data provided by the Office for Pedological and Agrochemical Studies of Iasi, the National Agency for Land Improvement, North Moldova subsidiary and the National Institute for Research and Development for Land Improvement, Iasi branch. Case studies are also presented for the situation in representative communal territories. In order to achieve the proposed objective, the data obtained from the survey of topographical maps (sc 1: 50 000 and 1: 100 000) and soils (sc 1: 200 000). Avoiding the degradation of soil degradation on some slopes in Iasi county requires the immediate finding of solutions to reduce the water erosion within tolerable limits and to contribute to the stabilization of the sliding masses on the surfaces with potential conditions.
