Pastoral farming has been a feature of the Greek scene since antiquity. The geomorphology of the area, climatic conditions and the prevailing systems of agricultural production in lowland regions at any given time have all been conducive to the development and preservation of this productive system, principally of small ruminants, until the present day.In the present paper, a brief review is presented of the pastoralism system in the area of Greece through the millennia, highlighting the variety of driving forces on pastoralism. Importance is stressed on this human activity to the formation of present-day biodiversity.Over the last decades, the pastoralist system has been subjected to pressures for 'modernization' and intensification like the rest of the agricultural sector in Greece and has been influenced by the social demands and constraints imposed on individuals in the farming community by these same modernising processes. Adaptation to modern conditions has been accompanied by rapid contraction of the pastoral system, despite the noteworthy economic role it purportedly has to play in the national economy, not to mention its social role in keeping alive the steadily decaying mountainous and disadvantaged regions, which constitute a considerable proportion of the rural land area of Greece. An attempt is made to foresee the future of this system by examining the dynamics of each component.
