The growth of trees is a key ecological parameter of forests and thus of high importance as an indicator of forest condition in long-term forest monitoring. Forest growth can be easily and fairly inexpensively assessed on both intensive monitoring plots and large-scale plots. For intensive monitoring plots, we propose a hierarchical system of stem diameter measurements with simple manual growth assessments in regular multiannual intervals on all trees (periodic measurements), annual to weekly readings of permanently installed girth bands (permanent measurements) on a subset of trees, and electronically recorded dendrometer measurements with high-time resolution on a few selected trees (continuous measurements) for physiological measurements. For this, we describe possible plot layouts, sampling protocols for the trees, and measuring methods and instruments used, and give suggestions for data Quality Assurance, forest growth calculations, and data evaluations.

Provides an assessment of the international forest regime, in reponse to calls from many quarters, including the UN Intergovernmental Forum on Forests (IFF) and the World Commission on Forests and Sustainable Development, as well as several NGOs. The focus is mainly on action taken by countries at the global level, in the framework of legally binding instruments and institutions. It builds on previous analyses of the international forest regime by looking beyond the legal mandates to begin exploring the actual performance of the components against their mandates. With the Intergovernmental Panel on Forests (IPF) Proposals for Action as the point for departure, the effectiveness and impact of individual legal instruments and global instutions are analyzed, as is the potential for synergy between them.

Covering recent developments in satellite observation data undertaken for monitoring forest areas from global to national levels, this book highlights operational tools and systems for monitoring forest ecosystems. It also tackles the technical issues surrounding the ability to produce accurate and consistent estimates of forest area changes, which are needed to report greenhouse gas emissions and removals from land use changes. Written by leading global experts in the field, this book offers a launch point for future advances in satellite-based monitoring of global forest resources. It gives readers a deeper understanding of monitoring methods and shows how state-of-art technologies may soon provide key data for creating more balanced policies.

Maintaining forest biodiversity by combining protection, management and restoration of forest and woodland landscapes is a central component of sustainable development. Evidence that there are threshold levels for how much habitat loss may be tolerated for viable populations of specialised species to be maintained. Policy-makers, businesses and managers pose questions about how to balance use of renewable forest resources and conserve biodiversity. Examples are presented on how biodiversity assessments can be made. Proposes how the critical gaps in our knowledge identified throughout the book could be filled through macroecological research and international co-operation.

Deforestation is frequently a topic of discussion in the environmental arena, but it is not just the number of trees that matters; the quality of the forest is also important. Even where the forest area is stable or increasing, there are often rapid changes in its character. Natural forests are being replaced by plantations or by intensively managed forests. Around the world, forests are becoming younger and less diverse, in both species and structure; this has important impacts for biodiversity and also affects many human values. In this groundbreaking text, forest quality is discussed as a useful new concept in forest conservation and management. Three main assessment criteria are used: authenticity; environmental benefits; and social and economic benefits. The book describes a methodology and protocol for collecting and analysing data, and outlines in detail the approach required with each indicator. The authors advocate a landscape approach to assessment and demonstrate how assessment works through a series of case studies that show how this approach can be used in many ways to help forest conservation management. This hands-on manual is for professionals involved in forestry, conservation and resource management worldwide, and contains case study material from Europe, Asia, Africa and Latin America that demonstrates practical uses of the new 'landscape' approach to forest conservation.

Lakes of Africa: Microbial Diversity and Sustainability examines microbial ecosystems in African lakes, including the history and formation of African lakes. The book describes how environmental stressors—including seasonal variations, climate change, and anthropogenic activities—affect microbial ecosystem dynamics in African lakes and the microbial responses to these stressors. The book explores and evaluates extremophiles in African lakes, including industrial biotechnology applications. The book highlights challenges facing microbial ecology in African lakes, as well as the design of models for solving these problems and predicting the future of lake microbial ecosystem sustainability. - Includes unique case studies on both African lakes and brine lakes, providing real life examples of the topics discussed - Provides a foundational background to the topic - Presents definitions throughout, whenever a new term is introduced, for a seamless reading experience and background information

First Published in 1998. In this seventh annual edition of VITAL SIGNS the team at the Worldwatch Institute bring together an eclectic selection of disparate trends to offer a unique, multifaceted view of our rapidly changing world. This vital resource and reference guide traces the scientific, social, economic and environmental trends that have and continue to shape our world. Among the trends covered for the first time in VITAL SIGNS 1998-99, are frontier forests, plantation forestry, satellite launches, minerals exploration, small arms proliferation and female education. This year's edition points out that global emissions of carbon, the leading contributor to global climate change, hit another new high, while wind power has grown an amazing 26 per cent per year, and sales of solar cells jumped a phenomenal 43 per cent in 1997. VITAL SIGNS is the most comprehensive source of environmental and social information available.
