Book Description
There is a growing need for appropriate management of aquatic plants in rivers and canals, lakes and reservoirs, and drainage channels and urban waterways. This management must be based on a sound knowledge of the ecology of freshwater plants, their distribution and the different forms of control available including chemical, physical, biological and biomanipulation. This series of papers from over 20 different countries was generated from the highly successful European Weed Research Society symposia on aquatic plant management, this being the ninth. The contributions provide a valuable insight into the complexities involved in managing aquatic systems, discuss state-of-the-art control techniques such as biomanipulation using fish and waterfowl and the use of straw, and deal with patterns of regrowth and recovery post-management. Careful consideration is given to the use of chemicals, a practice which has come under scrutiny in recent years. Underpinning the development of such control techniques is a growing body of knowledge relating to the biology and ecology of water plants, including growth responses under different trophic conditions, the impact of pollution, and aspects of photosynthesis. The authorship of the papers represents the collective wisdom of leading scientists and experts from fisheries agencies, river authorities, nature conservation agencies, the agrochemical industry and both governmental and non-governmental organisations.

Book Description
This book tells the story of development studies in practice over the last fifty years through the work of one remarkable individual, Robert Chambers. His work has taken him from being a colonial officer in Kenya through training and managing large rural development projects to a fundamental critique of top-down development and the championing of participatory approaches. The contributors eloquently demonstrate how he has been at the centre of major shifts in development thinking and practice over this period, popularising terms that are now at the centre of the development lexicon such as vulnerability, multi-dimensional poverty, sustainable livelihoods and 'farmer first'. Robert Chambers played a major role in the massive growth in participatory approaches to development, and particularly the application of participatory methods in development research and appraisal. This has led to fundamental challenges to development practice, ranging from approaches to monitoring and evaluation to institutional learning and professional training. There is probably no-one who has had more influence on approaches to development in the past decades. Revolutionizing Development offers a unique overview of these contributions in thirty-two concise chapters from authors who have been intimately involved as collaborators, critics and colleagues of Robert Chambers.

Book Description
The lack of sufficient access to clean water is a common problem faced by communities, efforts to alleviate poverty and gender inequality and improve economic growth in developing countries. While reforms have been implemented to manage water resources, these have taken little notice of how people use and manage their water and have had limited effect at the ground level. On the other hand, regulations developed within communities are livelihood-oriented and provide incentives for collective action but they can also be hierarchal, enforcing power and gender inequalities. This book shows how bringing together the strengths of community-based laws rooted in user participation and the formalized legal systems of the public sector, water management regimes will be more able to reach their goals.
