    Modeling Historic Rangeland Management and Grazing Pressures in Landscapes of Settlement

    Defining historic grazing pressures and rangeland management is vital if early landscape threshold crossing and long鈥搕erm trajectories of landscape change are to be properly understood. In this paper we use a new environmental simulation model, B煤model, to assess two contrasting historical grazing landscapes in M媒vatnssveit Iceland for two key periods鈥攖he colonization period (ca. Landn谩m, A.D. 872鈥1000) and the early eighteenth century A.D. Results suggest that there were spatial and temporal variations in productivity and grazing pressure within and between historic grazing areas and indicate that land degradation was not an inevitable consequence of the livestock grazing introduced with settlement. The results also demonstrate the significance of grazing and livestock management strategies in preventing overgrazing, particularly under cooler climatic conditions. The model enables detailed consideration of historic grazing management scenarios and their associated landscape pressures

    Ecological Economics and Human Ecology

    While economic theory has been enormously influential since the eighteenth century, the level of dominance of culture, politics and ethics gained by it in the last few decades is unprecedented. Not only has economic theory taken the place of political philosophy and ethical discourse and imposed its own concepts and image of society on other social sciences, it has redefined the natural sciences through its own categories as nothing but instruments of production, investment in which is to be judged in terms of its profitability. In this chapter I challenge all this, arguing for the primacy of political philosophy inspired by T.H. Green, showing how A.N. Whitehead provided the natural philosophy to defend Green's social liberalism. I then defend ecological economics and human ecology based on assumptions deriving from Whitehead to replace current economic and political doctrines as the basis for formulating public policy

    Ecology and the Common Good: Sustainability and Catholic Social Teaching

    Get PDF
    In recent years official Roman Catholic documents have addressed the ecological crisis from the perspective of Catholic social teaching. This expansion of Catholic social thought addresses the social and ecological question. This paper links environmental and human ecology with the concept of sustainability and proposes an interpretation of the common good and a definition of sustainability within Catholic social teaching. Our treatment of sustainability and Catholic social teaching includes: an analysis of the ecological processes that sustain nature; insights from human ecology, and an examination of models of sustainability as a foundation for re-structuring society to promote the common good. The paper provides a summary of the historical expansion of the common good within modern Catholic social thought, and concludes with an ecological interpretation of the common good and a definition of sustainability within the Catholic understanding of justice
