Atmospheric Inputs

Abstract. This contribution to the Spot-On volume considers the magnitude and composition of atmospheric nitrogen inputs to the oceans and then goes on to consider the impacts of these inputs. Effects in open ocean and coastal areas are probably different. Offshore atmospheric inputs may produce a small enhancement of overall ocean productivity and hence CO2 drawdown. In coastal waters atmospheric inputs contribute significantly to overall eutrophication pressure, but evidence that they trigger algal blooms is limited. Management of atmospheric inputs to coastal waters to mitigate eutrophication pressures requires that emissions be managed over a wide area reflecting the efficient long range transport of atmospheric nitrogen. Strategies for management of oxidised and reduced nitrogen deposition will be different reflecting their different rates of deposition.

The Military

This article explains why the Chosŏn government and the military in particular expanded state control over forests in the seventeenth century and analyzes the implications of forest administration in a preindustrial polity. From 1592 to 1598, the Chosŏn dynasty suffered invasions from Japan that displaced much of the Korean population and devastated the economy and environment. The crucial role of the navy during the war, along with a dire postwar situation, heightened government anxieties about deforestation and timber scarcity. Thus, in the seventeenth century, the Chosŏn government expanded administration over forests, particularly pine forests, across the coasts and islands of southwestern Korea. The key vehicle for the expansion was the military. Due to wartime and postwar exigencies, the military became the late Chosŏn state's primary organ for management of wood resources for state purposes. Furthermore, the growth of pine-centric state forests and shifts in military priorities would significantly reshape Korean ecologies.
