<Lakes and Reservoirs - Similarities, Differences and Importance>

Foreword

We are pleased to present you with this Short Series related to the management of lakes and reservoirs. These water bodies are one of the most important sources of fresh water for agriculture, industry, domestic and drinking purposes while at the same time are the “homes” of a number of different and important species of plants and animals making them sources of fisheries, areas for migratory birds to reproduce or rest, etc..

In general, we are not aware of the efforts required for keeping lakes and reservoirs in good condition so that they can be used for the benefit of society as well as for nature. An enormous amount of money, technical and scientific expertise is required to keep them clean and healthy, which in many occasions is taken for granted.

As the human population grows in the future more demand will be put on lakes and reservoirs. Water levels will become lower as a result of higher consumption from households and industries; an increasing number of people will enjoy them resulting in altering their shores; non-appropriate use of the land, particularly on the hills and mountains, may result in increasing the amount of soil or sediments reaching their basins. Finally, pollution from agricultural lands and domestic sources may produce eutrophication and non-desirable effects such as the presence of toxic algae, reduction of oxygen and generation of foul odour, amongst other negative effects.

With this Short Series UNEP-IETC, ILEC and the Japanese Environment Agency intends to provide information about lakes and reservoirs considering various aspects related to their nature, importance and management. It is not meant to be a comprehensive technical publication but an accessible and amenable source of information for the citizen by the use of clear language and a minimum of technical jargon to encourage greater understanding.

The intrinsic value of lakes and reservoirs and the efforts to preserve them are larger than we think and as citizens we have to join our efforts with that of the authorities and industries to ensure their preservation and appropriate or sustainable use either for us or for future generations. We sincerely hope that you find the information in this publication interesting and stimulating.
