Sustainable management

There is a further complication in shallow lakes containing macrophytes (aquatic flowering plants, pteridophytes, and macroalgae). These take up and accumulate nutrients from the water and from the aquatic soil in which they are rooted (sediment). Although these plants are sometimes classed as nuisance weeds, they nevertheless act as an important alternative sink for nutrients which are denied to the plankton. In recent times, a key role of macrophytes in the successful and sustained management of water quality has been identified and explained. ... 

Need of sustainable management (ecological, economical, and social). There is a need for sustainable water resources management, but this can also be the most difficult to recognize. Management should be respectful with the environment, but not at any economical and social prize economically affordable, but not at any environmental and social cost and finally, must seek for social equity (personal and territorial), but not at any environmental and economical cost. Besides there is an interrelation among the different problems related to IWRM, each problem can have different causes and each solution may affect to different problems.

For all future activities, and in order to achieve sustainable management of water resources, including related soil and sediment compartments, the strategy to be followed should involve (i) the precautionary principle, (ii) polluter pays principle and (iii) application of the best available techniques (BATs) and best environmental practices, including where appropriate, clean technologies. 

The European Union (EU) environmental policy has put water protection and its sustainable management high on its agenda, reflected by the European Water Framework Directive (WFD), which is now in its implementation phase. 

The sustainable management of sediments, in addition to water, soil and sludge environmental matrices, in relation to surfactant regulations, is also an important and relevant issue. The US EPA has recently shown concern regarding the levels of surfactants in sediments and has thus released a Draft Contaminated Sediment Science Plan. In this draft, recommendations for the development of analytical methods and evaluations of the toxicity and risk assessment of Emerging endocrine disrupters like APEOs and their metabolites in sediment samples are outlined. 

Strengthening Science-Based Decision Making for Sustainable Management of Ground Water in Mexico was a joint workshop between the U.S. National Academies and the Mexican Academy of Sciences. It was held February 8-10, 2004, in Merida, Mexico. 

Lumber is potentially the most environmentally friendly of all building materials, and can be used for surfaces, fences, screens, and supports. In an organic garden it is important to use lumber from sustainably managed forests, whatever the type of wood and the country it comes from. Look for the Forest Stewardship Council (FSC) label, which guarantees that the wood comes from a well-managed, sustainable forest. Coppice wood (see p.l58) is also a sustainable resource, cut from mixed woodlands that in themselves are a valuable wildlife habitat. 

After the law passed, the political debate about the sustainable management of hydropower came to a standstill. The law could only be applied in the context of a renewal of the water use licenses. In Switzerland these licenses typically run over 80 years and therefore no major changes in operation could be expected before the year 2020. Furthermore, the deregulation of electricity markets begun to shape expectations in Switzerland. This new market order put pressure on hydropower operators to reduce cost and to act as competitive firms. Environmental requirements were considered as a direct threat to economic survival of the plants.

The Chemical Leasing (ChL) approach is a new and innovative instrument to promote sustainable management of chemicals and close the material cycles between suppliers and users of chemicals ("closing the loops"). Chemical Leasing is applicable to large companies as well as small and medium size enterprises of different sectors. Experience shows that these new models reduce ineffective use and over-consumption of chemicals and help companies to enhance their economic performance.
