In 1997, New York City adopted a mammoth watershed agreement to protect its drinking water and avoid filtration of its large upstate surface water supply. Shortly thereafter, the NRC began an analysis of the agreement's scientific validity. The resulting book finds New York City's watershed agreement to be a good template for proactive watershed management that, if properly implemented, will maintain high water quality. However, it cautions that the agreement is not a guarantee of permanent filtration avoidance because of changing regulations, uncertainties regarding pollution sources, advances in treatment technologies, and natural variations in watershed conditions. The book recommends that New York City place its highest priority on pathogenic microorganisms in the watershed and direct its resources toward improving methods for detecting pathogens, understanding pathogen transport and fate, and demonstrating that best management practices will remove pathogens. Other recommendations, which are broadly applicable to surface water supplies across the country, target buffer zones, stormwater management, water quality monitoring, and effluent trading.
The purpose of this report is to review and summarise published research on the efficiency and management of riparian buffer zones (RBZ) with respect to the attenuation of sediment and nutrients, and biodiversity enhancement. While there have been numerous studies on the efficiency of RBZ with respect to sediment and nutrients, many of these studies have been small-scale and site-specific. Therefore, a review of these studies needs to consider an assessment of the catchment scale factors that influence the effectiveness of RBZ in attenuating catchment loads.
Management planning guidelines represent the second major step in the process for planning protected areas, following implementation of the Establishment Guidelines. This publication was developed as a part of the Conservation and Sustainable Management of Turkeys’ Steppe Ecosystem Project. It is the one of seven sets of guidelines designed for the development of recommendations and strategies for the management of the country’s natural assets. This guidelines are based on international and national standards and are divided into 15 steps for successful management. A fundamental pre-condition for any form of management planning is clear definition of the overall management objectives to be achieved. These management objectives are linked to the IUCN protected area categories, which form the basis for the guidelines. Important recommendations for successful management include the creation of thematic preparatory maps on topography, habitats, borders and zones, and habitat-based planning. The guidelines provide basic recommendations for the integration of global trends and requirements connected with nature conservation and protected areas into the protected area management process. A central element of this process is the management plan, which sets out the management approach and goals, together with a framework for decision-making to be applied in the protected area over a given period of time. The management plan is usually valid for a period of 10 years but may include a mid-term review. Changes can only be made to the plan on the basis of ecological or natural reasons.
Provides guidance to States on how to ensure effective application of water quality standards to wetlands. The basic requirements include: wetlands in the definition of 3State Waters2; designate uses for all wetlands; adopt aesthetic narrative criteria for wetlands; adopt narrative biological criteria for wetlands; and apply the State1s antidegradtion policy and implementation methods to wetlands.
