Sustainable land management refers to the activities of humans and implies that activity will continue in perpetuity. It is a term that attempts to balance the often conflicting ideals of economic growth and maintaining environmental quality and viability....

  • Failure to adequately define [sample] support has long been a source of confusion in site characterization and remediation because risk due to long-term exposure may involve areal supports of hundreds or thousands of square meters; removal by backhoe or front-end loader may involve minimum remediation units of 5 or 10 m2; and sample measurements may be taken on soil cores only a few centimeters in diameter. (Englund and Heravi, 1994) The importance of this observation cannot be overstated.

  • An environmental impact statement (EIS), under United States environmental law, is a document required by the National Environmental Policy Act (NEPA) for certain actions "significantly affecting the quality of the human environment".[1] An EIS is a tool for decision making. It describes the positive and negative environmental effects of a proposed action, and it usually also lists one or more alternative actions that may be chosen instead of the action described in the EIS. Several US state governments require that a document similar to an EIS be submitted to the state for certain actions.

  • Water quality is one of the key factors affecting the environmental health of the Mekong river system. As the livelihoods of most of the 60 million people who live in the Lower Mekong Basin (LMB) wholly or partly depend on aquatic resources, the environmental health of the river is a major concern to the governments of the countries in the basin. In 1985, the Mekong River Commission (MRC) established the Water Quality Monitoring Network (WQMN) to provide an ongoing record of the water quality of the river, its major tributaries, and the Mekong Delta.

  • 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....

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.
