Book (series)Manual / guideA guide to forest–water management 2021Many people worldwide lack adequate access to clean water to meet basic needs, and many important economic activities, such as energy production and agriculture, also require water. Climate change is likely to aggravate water stress. As temperatures rise, ecosystems and the human, plant, and animal communities that depend on them will need more water to maintain their health and to thrive. Forests and trees are integral to the global water cycle and therefore vital for water security – they regulate water quantity, quality, and timing and provide protective functions against (for example) soil and coastal erosion, flooding, and avalanches. Forested watersheds provide 75 percent of our freshwater, delivering water to over half the world’s population. The purpose of A Guide to Forest–Water Management is to improve the global information base on the protective functions of forests for soil and water. It reviews emerging techniques and methodologies, provides guidance and recommendations on how to manage forests for their water ecosystem services, and offers insights into the business and economic cases for managing forests for water ecosystem services. Intact native forests and well-managed planted forests can be a relatively cheap approach to water management while generating multiple co-benefits. Water security is a significant global challenge, but this paper argues that water-centered forests can provide nature-based solutions to ensuring global water resilience.

Book (stand-alone)Technical bookRattan: current research issues and prospects for conservation and sustainable development 2002
Also available in:
No results found.According to an estimate made by the International Network for Bamboo and Rattan (INBAR), the global local usage of rattan is worth US$ 2.5 billion and external trade of rattan is estimated to generate US$ 4 billion. Seven hundred million people worldwide use rattan. Most of the raw material for local processing and for supplying the rattan industry is still obtained by harvesting of unmanaged, wild rattan resources in natural tropical forests. Only a very small share is obtained from rattan pla ntations. The huge economic and social importance of the rattan sector is based on a fast dwindling stock of wild rattan resources available in the forests, particularly of tropical Asia, and therefore compromising its future outlook.
