Book Description
Many 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 Description
The United Nations World Water Assessment Programme (WWAP) is hosted and led by UNESCO. WWAP brings together the work of 31 UN-Water Members as well as 37 Partners to publish the United Nations World Water Development Report (WWDR) series. Under the theme Water for Sustainable Development, the WWDR 2015 has been prepared as a contribution from UN-Water to the discussions surrounding the post-2015 framework for global sustainable development. Highlighting water's unique and often complex role in achieving various sustainable development objectives, the WWDR 2015 is addressed to policy- and decision-makers inside and outside the water community, as well as to anyone with an interest in freshwater and its many life-giving benefits. The report sets an aspirational yet achievable vision for the future of water towards 2050 by describing how water supports healthy and prosperous human communities, maintains well functioning ecosystems and ecological services, and provides a cornerstone for short and long-term economic development. It provides an overview of the challenges, issues and trends in terms of water resources, their use and water-related services like water supply and sanitation. The report also offers, in a rigorous yet accessible manner, guidance about how to address these challenges and to seize the opportunities that sound water management provides in order to achieve and maintain economic, social and environmental sustainability.

Book Description
The State of the World's Land and Water Resources for Food and Agriculture is FAO's first flagship publication on the global status of land and water resources. It is an 'advocacy' report, to be published every three to five years, and targeted at senior level decision makers in agriculture as well as in other sectors. SOLAW is aimed at sensitizing its target audience on the status of land resources at global and regional levels and FAO's viewpoint on appropriate recommendations for policy formulation. SOLAW focuses on these key dimensions of analysis: (i) quantity, quality of land and water resources, (ii) the rate of use and sustainable management of these resources in the context of relevant socio-economic driving factors and concerns, including food security and poverty, and climate change. This is the first time that a global, baseline status report on land and water resources has been made. It is based on several global spatial databases (e.g. land suitability for agriculture, land use and management, land and water degradation and depletion) for which FAO is the world-recognized data source. Topical and emerging issues on land and water are dealt with in an integrated rather than sectoral manner. The implications of the status and trends are used to advocate remedial interventions which are tailored to major farming systems within different geographic regions.
