This book is the first part of the Proceedings of the 26th congress of SIL
(Societas Internationalis Limnologiae Theoreticae et applicatae) held in Sao
Paolo, Brazil in 1994. It contains the papers of all plenary lectures
given at that congress. The meeting had the theme ``Water as a limiting
resource: Conservation and Management''.
The fifteen papers in this volume cover a wide range of topics,
such as limits on life in lake ecosystems, renewal of floodplain forests along
rivers, saline lake problems, river water quality issues, water resource and
scarcity issues in India, ecosystem theory and biogeochemical cycles of large
rivers, to name a few. Please see the table of contents below for details.
Because of the worldwide impact of the issues discussed in the plenary
lectures, SIL thought it important to make this unique collection of papers
available to the wide audience outside of its organization.
