A guide to forest–water management by Food and Agriculture Organization of the United Nations,International Union of Forest Research Organizations,U.S. Department of Agriculture Pdf
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.

Advancing the forest and water nexus by Food and Agriculture Organization of the United Nations Pdf
Forests are intrinsically linked to water – forested watersheds provide 75 percent of our accessible freshwater resources (Millennium Ecosystem Assessment, 2005) – and both forest and water resources are relevant to the achievement of all 17 Sustainable Development Goals. Despite the important interlinkages, the forest-water nexus is often unaccounted for in policy and planning. For example, three quarters of forests are not managed for soil and water conservation, which poses a fundamental challenge to achieving sustainable and resilient communities and ecosystems. It is paramount to employ an integrated approach to forest and water resources in management and policy that takes into account the complexity and contextual nature of forest-water relationships. To achieve this, we must improve our understanding of forest-water relationships within local contexts and at different scales, as well as our ability to design, implement, and learn from landscape approaches that both rely on these forest-water relationships, and impact them. In this context, FAO’s Forest and Water Programme has developed a module-based capacity development facilitation guide for project and community stakeholders involved in forest, water and natural resource management to ensure we apply our knowledge to better manage forests and trees for their multiple benefits, including water quantity, quality and the associated socio-economic benefits that people within and outside forests so heavily depend on.
Technical Guide to Managing Ground Water Resources by U.s. Department of Agriculture Forest Service,U.S. Geological Survey,U.s. Bureau of Land Management Pdf
Ground water is the Nation's principal reserve of fresh water and represents much of its potential future water supply. Ground water on National Forest System (NFS) lands is a major contributor to flow in many streams and rivers and has a strong influence on the health and diversity of plant and animal species in forests, grasslands, riparian areas, lakes, wetlands, and cave systems. It also provides drinking water to hundreds of communities. Demands for safe drinking water and requirements to maintain healthy ecosystems are increasing, and complex social and scientific questions have arisen about how to assess and manage the water resources on NFS lands. This technical guide was developed to help address these issues. Today, many of the concerns about ground water resources on or adjacent to public land involve questions about depletion of ground water storage, reductions in streamflow, potential loss of ground water-dependent ecosystems, land subsidence, saltwater intrusion, and changes in ground water quality. The effects of many human activities on ground water resources and on the broader environment need to be clearly understood in order to properly manage these systems. Throughout this technical guide, we emphasize that development, disruption, or contamination of ground water resources has consequences for hydrological systems and related environmental systems. Ground water and surface water are interconnected and interdependent in almost all ecosystems. Ground water plays significant roles in sustaining the flow, chemistry, and temperature of streams, lakes, springs, wetlands, and cave systems in many settings, while surface waters provide recharge to ground water in other settings. Ground water has a major influence on rock weathering, streambank erosion, and the headward progression of stream channels. Pumping of ground water can reduce river flows, lower lake levels, and reduce or eliminate discharges to wetlands and springs. It also can influence the sustainability of drinking-water supplies and maintenance of critical ground water-dependent habitats. Increasingly, attention is being placed on how to manage ground water (and surface-water) resources on public lands in a sustainable manner. The potential for ground water resources to become contaminated from anthropogenic as well as natural sources is being scientifically assessed. Each ground water system and development situation is unique and requires a specific analysis to draw appropriate conclusions. This technical guide begins by reviewing the legislative and policy framework, and the issues related to ground water inventory, monitoring, contamination, and development. Individual sections then focus on key concepts, principles and methods for managing ground water resources. Relevant special topics, case studies, and field examples are highlighted throughout the text. Additional information on some topics can be found in the appendixes. This technical guide provides guidance for implementing the U.S. Department of Agriculture (USDA) Forest Service national ground water policy. It describes hydrological, geological, and ecological concepts, as well as the managerial responsibilities that must be considered to ensure the wise and sustainable use of ground water resources on NFS lands. This document is one part of a four-part information system on ground water management on the national forests and grasslands. The other three parts are (1) Forest Service policy on ground water (Forest Service Manuals [FSM] 2543 and 2880); (2) a Forest Service sourcebook on State ground water laws, regulations, and case law for all 43 States with NFS land; and (3) a ground water inventory and monitoring technical guide. When complete, the four parts will provide line officers and technical specialists at all field levels with the science, policy, and legal framework for Forest Service ground water-resource management.
Forest management and the impact on water resources by García Chevesich, Pablo,Neary, Daniel G.,Scott, David F.,Benyon, Richard G.,Reyna, Teresa Pdf
Trees have been around for more than 370 million years, and today there are about 80 thousand species of them, occupying 3.5 billion hectares worldwide, including 250 million ha of commercial plantations. While forests can provide tremendous environmental, social, and economic benefits to nations, they also affect the hydrologic cycle in different ways. As the demand for water grows and local precipitation patterns change due to global warming, plantation forestry has encountered an increasing number of water-related conflicts worldwide. This document provides a country-by-country summary of the current state of knowledge on the relationship between forest management and water resources. Based on available research publications, the Editor-in-Chief of this document contacted local scientists from countries where the impact of forest management on water resources is an issue, inviting them to submit a chapter.
A guide to multiple-use forest management planning for small and medium forest enterprises by Food and Agriculture Organization of the United Nations Pdf
This publication discusses the concept, evolution, and requirements of forest management planning, focusing on multiple-use forest management and small and medium forest enterprises (SMFEs). Forest management planning is a document that translates forest policies into a coordinated programme for managing forests over a set period of time, integrating environmental, economic, and social dimensions. It serves various purposes, such as legal documents, concession agreements, and tools for sustainable forest management. Multiple-use forest management recognizes the diverse values and benefits that forests provide beyond timber, such as water regulation, climate change mitigation, biodiversity conservation, and cultural values. Despite its challenges, forest management planning can contribute to sustainability and optimize the value derived from forests. SMFEs play a crucial role in supporting livelihoods and forest-based economies. However, barriers such as policy environments, lack of support tools, and management challenges need to be addressed. Forest management planning can help overcome these barriers by ensuring legal compliance, mitigating risks, promoting sustainability, and supporting marketing and value chain development. It is also a valuable tool for empowering local forest users, involving stakeholders, and negotiating benefit-sharing arrangements.The process of forest management planning involves gathering information, defining objectives, developing silvicultural and ecosystem services plans, creating a business plan, planning for unusual events, and establishing a monitoring system. It is an adaptive learning process that continuously evaluates and adapts plans based on the results of forest management activities. Stakeholder engagement is key to developing a socially acceptable forest management plan, starting with identifying stakeholders, creating awareness, informed discussions, and monitoring to keep stakeholders accountable for their agreed responsibilities. Negotiating expectations and building consensus helps identify conflicts and integrate qualitative data to improve decision-making in multiple-use forest management.In conclusion, forest management planning is essential for sustainable forest management, contributing to the well-being of communities, the environment, and the economy. This guide provides a framework for forest management planning, guiding forest managers through the planning process stepwise and providing advice on information sources needed during the planning process. The framework can be adapted to national and local contexts in line with relevant regulatory requirements.
Climate Change Adaptation and Mitigation Management Options by James M. Vose,Kier D. Klepzig Pdf
Forest land managers face the challenges of preparing their forests for the impacts of climate change. However, climate change adds a new dimension to the task of developing and testing science-based management options to deal with the effects of stressors on forest ecosystems in the southern United States. The large spatial scale and complex interactions make traditional experimental approaches difficult. Yet, the current progression of climate change science offers new insights from recent syntheses, models, and experiments, providing enough information to start planning now for a future that will likely include an increase in disturbances and rapid changes in forest conditions. Climate Change Adaptation and Mitigation Management Options: A Guide for Natural Resource Managers in Southern Forest Ecosystems provides a comprehensive analysis of forest management options to guide natural resource management in the face of future climate change. Topics include potential climate change impacts on wildfire, insects, diseases, and invasives, and how these in turn might affect the values of southern forests that include timber, fiber, and carbon; water quality and quantity; species and habitats; and recreation. The book also considers southern forest carbon sequestration, vulnerability to biological threats, and migration of native tree populations due to climate change. This book utilizes the most relevant science and brings together science experts and land managers from various disciplines and regions throughout the south to combine science, models, and on-the-ground experience to develop management options. Providing a link between current management actions and future management options that would anticipate a changing climate, the authors hope to ensure a broader range of options for managing southern forests and protecting their values in the future.
Forest Hydrology by Devendra Amatya,Thomas Williams,Leon Bren,Carmen de Jong Pdf
Forests cover approximately 26% of the world's land surface area and represent a distinct biotic community. They interact with water and soil in a variety of ways, providing canopy surfaces which trap precipitation and allow evaporation back into the atmosphere, thus regulating how much water reaches the forest floor as through fall, as well as pull water from the soil for transpiration. The discipline "forest hydrology" has been developed throughout the 20th century. During that time human intervention in natural landscapes has increased, and land use and management practices have intensified. The book will be useful for graduate students, professionals, land managers, practitioners, and researchers with a good understanding of the basic principles of hydrology and hydrologic processes.
