Agricultural development was often accompanied by a diminishing rural population and the disintegration of communities, while exogenous factors such as warfare, epidemics, and market conditions also played a role. The affinity of conditions in rural areas was probably one of the reasons the Organization of American States entered into agreements for technical assistance from these countries in the early sixties, hoping to learn from the accumulated experience. The appearance of Jewish settlements in the traditional rural landscape has accelerated the process of modernization and brought about profound socioeconomic changes. The social organization of the Collective Moshav is a synthesis of the cooperative Moshav and the collective Kibbutz. Work is organized on a communal basis as in the Kibbutz; however, each family lives in its own house as in the Moshav and is free to dispose of its monthly budget according to its own preferences.
