Resource- and eco-effectiveness as a new paradigm of development to prevent resource depletion and environmental imbalance

SUMMARY

The increase in the number of golf courses around the world has been phenomenal, particularly since the 1990s where an estimated 350 new courses were added annually to the more than 25 000 existing ones. In terms of recreational sports spaces, golf arguably uses the greatest amount of land. Using the case study of Singapore, it is argued that the continual expansion of golf courses runs counter to the broad ideal of urban sustainability. The arguments that support golf course expansion viz. reducing the issue to a matter of supply and demand and extolling golfs economic benefits pay scant attention to principles of equity and sustainability. Although existing green spaces risk being converted into golf courses, golf course maintenance itself can be ecologically benign. However, the elitist nature of golf in Singapore ultimately imposes greater and unnecessary demands on resources in general. Given Singapore's land scarcity, golf course expansion is opposed not so much because of its ecological impacts but because of how it compromises spatial equity.     

Initial results from a multi-institutional collaboration to monitor harmful algal blooms in South Carolina

The rapid rate of development in the South Carolina (SC) coastal zone has heightened public concern for the condition of the state's estuaries, and alerted scientists to the potential that novel and adverse effects on estuarine ecosystems may result. Although well-developed databases from long-term monitoring programs exist for many variables valuable in predicting and following system responses, information on phytoplankton distributions in SC estuaries has lagged. Knowledge of the dynamical relationship between environmental (e.g., nutrient quantity and quality) and biological (e.g., grazing) regulation, and phytoplankton biomass and composition is critical to understanding estuarine susceptibility to eutrophication or harmful algal blooms (HABs). Recently, SC scientists from federal, state, and academic institutions established a collaborative monitoring program to assess HAB distribution and ecology statewide. The South Carolina Harmful Algal Bloom Program includes: a) intensive temporal monitoring at areas of known HAB occurrence or those exhibiting symptoms potentially related to HABs (e.g., prevalent fish lesions), b) extensive spatial monitoring in coordination with existing statewide efforts, c) a citizen volunteer monitoring network, d) nutrient response bioassays, and e) laboratory-based physiological experiments on HAB isolates. By combining trip-wire surveillance and rapid response systems, routine monitoring of environmental parameters and HAB distribution, and process-oriented studies examining the physiological functioning of HAB species, an enhanced understanding of the impact and environmental control of HABs in SC estuaries will be achieved. The application of this approach to studies on the distribution and physiological ecology of a new widespread SC red tide, and to the discovery of several potentially toxic blooms (including Pfiesteria) in SC holding ponds, are described.
