  • This report is ostensibly about land quality indicators (LQIs). However, anyone who reads it will find a useful compilation of advice, experience and opinion on why land quality information is important for sustainable development and how it can be used more effectively for planning and decision making. But the report also poses as many questions as it answers, which in itself reflects the diversity of viewpoints on indicators.

  • The new century has begun with some of the lowest grain prices in recent memory. From an economist’s vantage point, this is a sure sign of excess production capacity. However, there may be more here than meets the economist’s eye. Natural scientists, many of whom have contributed to this volume, see something very different. They see reason to be concerned about such issues as the overplowing of land and the overpumping of aquifers. They look at sustainable production and see a worrisome fraction of world food output being produced with the unsustainable use of land and water....

  • Landfills are excavated or engineered sites where non-liquid hazardous waste is deposited for final disposal and covered. These units are selected and designed to minimize the chance of release of hazardous waste into the environment. Design standards for hazardous waste landfills require a double liner; double leachate collection and removal systems (LCRS); leak detection system; run on, runoff, and wind dispersal controls; construction quality assurance (CQA) program. Liquid wastes may not be placed in a hazardous waste landfill.

  • A context-sensitive approach to sustainable planning and development helps to protect public health, safety, andwelfare. By avoiding inherent site problems, or constraints, and by capitalizing on inherent site assets, or opportunities, site planners can limit long-term maintenance costs and, more important, reduce the risks to life and property from natural hazards. The careful analysis of sites—and the site’s context—can lead to better development proposals and, ultimately, to higher-quality built environments. Qualified site planners and designers are vital to this process.
