Book excerpt: Preliminary experiments in 1968 indicated that water hyacinths and possibly other aquatic plants could be controlled by 10.6 micron laser radiation. Two effects were noted: an immediate plasmolysis directly proportional to laser energy and a secondary effect at lower levels of irradiation that resulted in death of the plant after a period of time. Studies made in 1969 indicated that split applications of laser energy were not more effective than continuous treatment. Plant count evaluations were significant at a minimum level of 0.5 joules per sqcm(J/sgcm). Histological examination of irradiated leaf tissue did not show extensive cell damage due to laser treatment. Studies made in 1970 indicated that twice-irradiated plants were affected at a level of about 70J/sqcm. (Author).

Download or read book Water Hyacinth written by Brij Gopal and published by Elsevier Publishing Company. This book was released on 1987 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is almost impossible for an individual to keep pace with the huge bulk of, not always readily accessible, literature on waterhyacinth which has amassed in recent years. This book provides for the first time a comprehensive bibliography of over 2700 references and a critical review of the current knowledge on all aspects of the plant. Important data on all these aspects have been compiled and presented in numerous tables and figures making the book the most important reference work to date on waterhyacinth. Areas requiring the extra attention of researchers are also indicated. In recent years aquatic weeds such as waterhyacinth have received great attention, not only for the magnitude of problems caused by them in the management of water resources, but also for the promise they hold as a new resource for such diverse uses as animal feed, compost, paper, energy (biogas) and above all the control of water pollution (wastewater treatment). Waterhyacinth outclasses all other aquatic weeds in its rate of growth, multiplication and dry matter production, and its potential ability in respect to energy and pollution control.

Available in PDF, EPUB and Kindle. Book excerpt: The 2020 edition of the WWDR, titled Water and Climate Change illustrates the critical linkages between water and climate change in the context of the broader sustainable development agenda. Supported by examples from across the world, it describes both the challenges and opportunities created by climate change, and provides potential responses – in terms of adaptation, mitigation and improved resilience – that can be undertaken by enhancing water resources management, attenuating water-related risks, and improving access to water supply and sanitation services for all in a sustainable manner. It addresses the interrelations between water, people, environment and economics in a changing climate, demonstrating how climate change can be a positive catalyst for improved water management, governance and financing to achieve a sustainable and prosperous world for all. The report provides a fact-based, water-focused contribution to the knowledge base on climate change. It is complementary to existing scientific assessments and designed to support international political frameworks, with the goals of helping the water community tackle the challenges of climate change, and informing the climate change community about the opportunities that improved water management offers in terms of adaptation and mitigation.
